face recognition cameras to stop children buying alcohol and cigarettes.

The supermarket chain Budgens has installed face recognition cameras in one of its stores to stop children buying alcohol and cigarettes.

It is thought to be the first time a UK retailer has used the technology to identify underage customers.

The scheme is being piloted at an unnamed branch of Budgens in London.

If the system recognises someone who has previously been unable to prove they are 18, a signal alerts the cashier who will refuse to serve them.

Facial recognition software makes a unique template of an individual’s features by taking measurements between key points on the face.

Magellan …Its time to just say NO to CCTV

More enhancemens for CCTV that  technology companies want councils and police to  buy. The question is do you want swimming pools, hospitals,  books in  schools,  or smart CCTV tracking our children.

Its time to just say NO  to  CCTV
The kit is already sold to sports marketing companies to measure a brand’s exposure on TV.

This system - called Magellan - automatically tells firms how many times their logo appeared during coverage of a particular event, its size, prominence and the length of time on screen.

“Previously there would have been people to do that, but it took five hours to analyse a 90-minute football game,” says Mr McIntosh.

Each unit costs about £100,000, with an additional fee for the marketing firms cover maintenance and support services.

DCI Neville has said he wants criminals to “fear” CCTV more, but the challenge for the police is getting the systems - and the budgets - in place to make the most of the images caught on camera.

visualization using rfid 2005

http://www.urban-atmospheres.net/Experiments/Testing/

The visualization was comprised of people (horizontal) and time (vertical).  Each individual was represented in a whole column.  The four regions were each color coded.  Each time an individual was detected in a specific region there ID number was flashed on the screen and the corresponding color denoted in their color for the current time.  A horizontal line indicated current time and was advanced downward ever minute.  Individuals that were not detected faded in color until they turned black.  Enter a new region generated a new color for the current time user’s column. 

Since the ID tags were handed out in numeric order you can see people first arriving at the party.  Later you can see them change color as they move around and eventually turn black when they leave.  The image represents a unique view of the social dynamics at play at this event.

The ASTRA project

The ASTRA project investigated the use of mobile ad hoc networks, and more specifically, ‘Smartdust’ for transport applications. The project examined the current state-of-the-art with Smartdust, using MOTES as the technology to be tested. It also looked at the likely market and technological advances of the Smartdust technology over the coming decade.

A trial using MOTES technology was hosted in Newcastle with a pervasive intelligent corridor established by a network of fixed MOTES on roads near Newcastle Central Station. Mobile MOTES were also placed in several buses. Communication between a static node and a moving node on-board a vehicle was achieved, showing that communication can take place between road side and vehicles using a network of MOTES. Evaluation of the system revealed that the main limitation of the technology at the present time is battery life.

gainspan…another wireless kit

Easy-to-use Wi-Fi Sensor Networks

http://www.gainspan.com/Software.htm

Managing a battery-powered sensor in a Wi-Fi sensor network presents unique needs for today’s Wi-Fi networks. Wireless sensor nodes spend most of their time with their radios off to conserve battery life, but today’s enterprise networks expect an “always available” interface from the wireless sensor networks and its individual sensor nodes.

To address this need, GainSpan developed GainSpan Management System (GMS), software that logically sits in the network as an “always on” interface using standard network protocols for management systems, including enterprise network management systems (NMS), as well as existing SCADA industrial and building automation systems.

GMS intelligently aggregates management and control requests and responses from the enterprise management systems and communicates with the sensor nodes to actively listen for configuration messages or firmware updates whenever they come on. This allows Wi-Fi based sensors to be seamlessly deployed in current enterprise networks, without degrading battery life.

Wireless sensors to midi

Eric Singer, creator of musical robots and maestro of LEMUR, the League of Electronic Musical Urban Robots, has unveiled a new wireless sensor-to-MIDI interface. It’s quite a bit pricier than the non-wireless MIDI models at US$495, but the payoff is a complete kit for wireless performance that promises to be resistant to both latency and interference. The receiver can be connected via either USB or MIDI, and the sensor unit has 20 inputs which you can mix and match as up to 10 analog ins and 20 digital ins. Put the sensor/transmitter unit wherever you like, then transmit data wirelessly to the receiver — so the sensors could be strapped to a dancer while a computer or synth receives the data elsewhere.

From the Times. by Alexi Mostrous and David Brown

Microsoft is developing Big Brother-style software capable of remotely monitoring a worker’s productivity, physical wellbeing and competence.

The Times has seen a patent application filed by the company for a computer system that links workers to their computers via wireless sensors that measure their metabolism. The system would allow managers to monitor employees’ performance by measuring their heart rate, body temperature, movement, facial expression and blood pressure. Unions said they fear that employees could be dismissed on the basis of a computer’s assessment of their physiological state.

Microsoft submitted a patent application in the US for a “unique monitoring system” that could link workers to their computers. Wireless sensors could read “heart rate, galvanic skin response, EMG, brain signals, respiration rate, body temperature, movement facial movements, facial expressions and blood pressure”, the application states.

The system could also “automatically detect frustration or stress in the user” and “offer and provide assistance accordingly”. Physical changes to an employee would be matched to an individual psychological profile based on a worker’s weight, age and health. If the system picked up an increase in heart rate or facial expressions suggestive of stress or frustration, it would tell management that he needed help.

The temperatare sensors in moteview on four of my motes show -273.15.

The temperatare sensors in moteview on four of my motes show -273.15.

The rest of the board ie light and sound is working.

How do I get the temp working or reset it.

Response:

—————————————————————

Did you “Reboot” into the new image (slot) that you OTAP’d?

This is required in order for the nodes to start executing new image.

You may choose any of the available slots where you want to store the

new image.

Please refer to the MoteConfig manual for details on OTAP.

The temperature sensors in moteview on four of my motes show -273.15. The rest of the board ie light and sound is working. How do I get the temp working or reset it.

Response:

—————————————————————

It looks like you are able to query the nodes (i.e. they are running OTAPImage).

Which Motes are you trying to reprogram with the new code?

Which slot have you selected to OTAP?

Please check and make sure that you have at least 2.7V battery voltage on these nodes.

Response:

—————————————————————

Unless you had previously enabled the nodes to be OTAP’d you won’t be able to OTAP with new application.

What I would suggest is to bring the nodes and attach them to the MIB board and then program them using MoteConfig’s Local program tab. You need to chek OTAP enable box if you wish to OTAP them in the future.

—————————————————————

Response

May be I wasn’t clear earlier. You can use both CA and CB boards in the same network. The main difference is that they use different power

control lines for temperature sensor. To get accurate temperature readings, you should Program the Mote attached to the CA sensor board (without jumper wire) with “XMTS300CA__.exe and program the Mote attached to the CB sensor board (with jumper wire) with “XMTS300CB__.exe

Response:

—————————————————————

It is quite likely that you have an MTS310CB board (look for a jumper

wire on the bottom-side of the sensor board).

The MTS310CA uses INT2 for temperature power control where as the CB version uses PW0. It sounds like you are using CA code on CB hardware (or vice versa) and hence the Temp sensor never gets turned on and returns 0.

If you have CB board, then you need to use CB version of the app.

Question:

—————————————————————

We want the batteries to last longer.

How do we do this?

How long should batteries last without a change….

If they are in low power mode how long will they last…

I know know this is difficult to answer) but how do I get them to last longer.

Also do you have solar panel one can plus in to the motes for power?

Response:

—————————————————————

The high power (HP) version of the apps don’t duty cycle the radio and hence would deplete the battery in few days. The low power (LP) version of the apps draw an average of 330 uA current with MICA2 platform and when used with alkaline AA batteries can easily deliver over 6 months of battery life.

In order to make the batteries in the Kits last long time, you need to use them in XMesh-LP mode.

We do have solar panel implementation in our next generation eKo Pro series products that can deliver battery life of over 5 years.

MTS420CC GPS driver issues

How does one get the GPS to work …?   MTS420CC GPS

Should the GPS data just show in moteview  once the board is connected…if its  working

ALL the other data is there but the GPS  is invalid  and showing long  and lat of 0

MTS420CC GPS driver issues. The GPS drivers distributed with MoteView and MoteWorks 2.0.F version have issues related to maintaining the GPS lock.

—————————————————————
For the GPS to work correctly and provide location data, you need to attach the GPS antenna to the MTS420CC board and have it located outdoors with optimal sky visibility.

If you are using MTS420CC, then there are updated GPS drivers that you should use,

1. Download the patch file and save it to /MoteWorks folder
2. Unzip from Cygwin using “tar -xzvf MTS420CCPatch.tgz”
3. This will extract the updated files into appropriate folders.
4. Now you should be able to compile and use the new drivers from /apps/xmesh/XMTS420CC directory

The pre-compiled apps (XMTS420CC_freq_hp.exe) to be used with MoteConfig are also included in the archive under the respective platform build folders.

Hi can this board with gps be programmed in LP low power mode. If so where is XMTS420 CC  lp ?

Response:
—————————————————————
The GPS receiver draws over 100 mA current and hence 2 AA batteries would last less than 20 hours.

Unless you use large solar panels, you won’t be able to recharge the batteries that fast. I am not aware of any such solar panels.

Question:
—————————————————————
Can this board with GPS be programmed in LP low power mode. If so where is XMTS420 CC  lp ?

Response:
—————————————————————
Te GPS receiver is a power hungry device and requires long time for warm-up/fix.
Hence there is no low power (LP) app available for MTS420CC.

———————————————————

- There is no GPS receiver that is currently available in the market
that can operate in a truly low power mode. The active current is ~100mA
and it takes over a minute for it to find satellite fix.
- That being the case, you can’t really operate the board in the lower
power mode from XMesh stand-point (i.e. if you have to wait for > 1
minute from the time you turn it on before you can get data why turn it
off, unless your read that data very infrequently?).
- We never tell any customers that they can operate MTS420 sensor boards
in low power mode nor have LP enabled apps for this. Who at Crossbow did
you talk to about LP operation of the MTS420?
- The product/technology has been used outdoors and for several months
operation (eg. eKo), but not with MTS420 or any GPS receiver.
-  In most applications, GPS data is used only during initial deployment
to identify the location of the nodes and their position is fixed from
then on. If you must need GPS location from the outdoor nodes, one
strategy I can propose is to turn on the GPS very occasionally (eg. once
a day) and at other times send only the sensor data (in LP mode). This
would require you to modify the existing MTS420 app and compile it under
LP mode.

Unreal City. Urban Experience in Modern European Literature and Art.

Unreal City. Urban Experience in Modern European Literature and Art.

Edited by Edward Tims and David Kelley. 

Manchester University Press. 1985ISBN 0 7190 1748 3

Page 1 Forward.

 Around the 1900 century the city became the focal point for an intense debate about the dynamics of technological civilization and its effects on the quality of human life. The Futurist manifesto of 909 identified the city as the pre eminent theme of modern poetry and painting.

 ….page 2 …”the Futurists picture the city as unstable and insecure”

page 3….as Ezra Pound pointed out in his comments on Eliot’s The Waste Land: “ the life of the village is narrative…..In a city the visual impressions succeed one another, overlap, overcross, they are cinematographic”.

 Page 4…The city ceases to be pictured as a social environment and it is transposed on to an existential plane. The metropolis ultimately becomes a metaphor – a dynamic configuration of the confiding hopes and fears of the twentieth century.

 Page 47 by Fank Whitford. “It was he constantly shifting experience of the city which concerned him (Monet), not the experience of living in it.”

 In 1914 Ludwig Meidner published and essay about painting urban subjects asserting that painting modern cities needs a different approach from Monet and the impressionists.

From Medneir.

“Let us paint what is close to us, our city world.! The wild streets , the elegance of iron suspension bridges, gas tanks in which hang in white – cloud mountains, the roaring colour of buses and express locomotives, the rushing telephone wires  aren’t they like music?), the harlequinade of advertising pillars, and then night….big city night”.

From Frank Whitford page 49…”for Meidner his conception of the city….had to be thoroughly subjective and could only be depicted in a fragmentary and metaphorical way.

Page 52….The visual aspects of the city is so complex, Kirchner argues, so different from one second to the next, that the painter must resort to exaggeration and other kinds of distortion in order to convey the authentic impression of it.


1912. The Street Enters The House” by Umberto Boccioni.  He included elements on the periphery of our vision and attempts to  evoke the sensation of  noise and colour by distorting forms and exaggerating colours. The city is growing before ours eyes.

Page 57…”Nature now seems finally to have been mastered. The City, in which nature was most obviously tamed, confined to parks, tubs and pots, seemed to be a symbol of that mastery”

Marinettis’s manifesto makes it clear that Futurism was an urban movement.

…page 58 “The city is a living thing, a restless superhuman creature in whose presence puny man can only stand and wonder”

In 1912 Robert Delauney painted “The City Of Paris modified after influence from the Futurists. Delauney describes this paintings as a “living and simultaneous”surface an “ensemble of rythms”. Quoted in Virginia Spate, Orphism (Oxford,1979), p.205 where The City of Paris is reproduced.

Stanza:
Writing played a huge part in the metaphorical and poetic interpretation of world cities. But it is through cinema that we can appreciate the scale, pace movement and patterns that where emerging in the modernist city. The imagined city is constructed in Fritz  Lang’s Metropolis (1926). It is an imagined city, a city of the future a city that is seen time and time again in modern science fiction films like The Fifth Element. Lang referred to The Tower of Babel, the massive control tower in Metropolis is called “The New Tower Of Babel. The comparison to
Babylon within the city has become common in metaphorical language of the city ever since cities really became too large for easy assimilation. Lang’s city thus becomes a city of “idea”.

Amorphoscapes: Net art and the audiovisual experience

Amorphoscapes: Net art and the audiovisual experience.

“A new aesthetic is emerging in which depth, narrative and meaning are being replaced with the pleasures of sensuous experience and spectacular effects.” (Lister et al. 2003)

Amorphoscapes

“An audio visual synthesis, a new kind of painting.” (Stanza)

Essential to the aesthetics that Stanza is trying to achieve is the importance of the aural experience alongside the visual experience. The audio and visuals must work together as a unit; therefore neither one is compromised for the benefit of the other.

Definitions

“amorphous”

to be without definite shape or structure

“scape”

a type of view or scene

Stanza’s definition:

“Audio visual relationships between art and science…maybe.”

Algorithm art

John Landsdown: “…devise an algorithm and see what sort of art it produces.” (Mealing 1997 p.15)

Cultural interface

“Cultural interfaces try to accommodate both the demand for consistency and the demand for originality.” (Manovich 2001, pp.90-91)

User is content

A.I. Richards stated that “…the meaning of a text resided not in its author’s intentions but in its reader’s legitimate…interpretations.”
(Levinson 1999, p.39)

McLuhan developed this theory further “…[from] the user interpreting the text to determining the text to being the text…The user is the content.” (Levinson 1999, p.39)

McLuhan describes this process of interaction as: “…the human being as an active master of media - not just sent through the media, but calling their shots, literally creating their content, and having unprecedented choice over what the content will be when it has already been created by someone else.” (Levinson 1999, pp.40-41)
