Bryce Bayer Died

via Image Sensors World by Vladimir Koifman on 11/21/12

Imaging Resource: Bryce Bayer, the Eastman Kodak scientist who invented the almost standard color filter pattern that bears his name, has passed away. Bayer, 83, died on November 13th in Bath, Maine. The Bayer Filter array was patented in 1976, U.S. Patent No. 3,971,065. Bayer is also known for his recursively defined matrix used in ordered dithering.

Update: SR kindly sent me a photo of Bryce Bayer's notebook describing his RGB pattern idea for the first time:

Gmail permette la ricerca negli allegati

via Downloadblog.it by Rosario on 10/2/12

Tra le varie migliorie che Google continua ciclicamente ad apportare a Gmail troviamo oggi un'interessante estensione della ricerca all'interno della webmail, che da ora fornirà anche risultati provenienti dagli allegati ai messaggi ricevuti.

Ai contenuti indicizzabili dal motore di ricerca interno a Gmail sono infatti stati aggiunti diversi formati, come file PDF, documenti Word, presentazioni PowerPoint e altri tipi di allegati diffusi che possano naturalmente essere "ricercabili" con del testo.

Il risultato è che per cercare un documento con allegati è possibile inserire has:attachment nel campo di ricerca, aggiungendo anche qualche keyword nel caso in cui si voglia appunto andare a guardare anche all'interno del contenuto di tali allegati. È inoltre possibile restringere la ricerca a determinati tipi di file, usando insieme a quanto appena mostrato anche l'opzione filename. Se per esempio si vuole cercare nelle email che contengono solo allegati di tipo PDF, sarà necessario inserire has:attachment filename:pdf.

STMicroelectronics details pressure sensor in your Galaxy S III, can tell when you're mountaineering

via Engadget by Jon Fingas on 9/6/12

If you're the sort to tear down your Galaxy S III, you might have noticed a mysterious STMicroelectronics LSP331AP chip lurking on the motherboard. While we've known that it's a pressure sensor, we now know that it's a new generation -- new enough that ST is just getting to explaining the technology to a mainstream audience. The piezoresistor-equipped MEMS chip tracks altitude through atmospheric pressure with an uncanny knack for precision; it can tell when you've crossing between floors, which could be more than handy for future iterations of indoor navigation. Don't worry if you're an extreme sports junkie that might push the limits, either. The sensor can do its job at the kinds of pressure you'd normally see when 32,800 feet high or 5,900 feet below sea level, which should keep it working even if you're checking your phone during a climb up K2 or a HALO skydive. We don't know if anyone beyond Samsung is lined up to use ST's pressure sensor in their devices, but we wouldn't be surprised if it becomes a mainstay for smartphones and outdoor gear in the near future.

MIT's 3D solar cells take cubism to new energy efficient heights

via Engadget by Joseph Volpe on 3/28/12

The promise of free energy is an enticing one -- that's free as in renewable source, not cost. (This is capitalism, after all, someone's got to foot the bill.) Economic gripes aside, research outfits like M.I.T. are getting us one step closer to this cleaner fuel future with the creation of three dimensional photovoltaic cells. The team's findings, recently published in the journal Energy and Environmental Science, demonstrate how these computer-modeled structures, rising upward in an unfolded accordion shape, have been proven to increase their energy yield over contemporary flat panels by up to 20 times in field and theoretical testing. This capacity gain, made possible by an efficient harvesting of sunlight during less optimal hours of the day, could be especially helpful in powering regions prone to overcast or wintry climates. The tech is still far from consumer friendly, though, with the actual price of the associated juice exceeding that of traditional solar tech. With continued improvements to the manufacturing process, however, residential and business customers could very well look forward to a future outfitted with solar towers only a Cubist could love.

Nessuno vuol produrre la caldaia del futuro

via NewsBlog by Gaetano by Gaetano on 3/21/12

Nessuno vuol produrre la caldaia del futuro:
Ieri sera ho visto in funzione una caldaia a pirolisi aperta. Costruirla costa 50 euro.
Il mio vicino di casa, Valerio Marchioni, è un genio costruttivo. E mi ha mostrato una cosa che credevo impossibile.
Prima di spiegare di cosa si tratta devo raccontare cos'è la pirolisi.
Da 150 anni conosciamo questa tecnologia rivoluzionaria, restata quasi inutilizzata (chissà perché).
Il principio scientifico è elementare: se metto della legna dentro un cilindro, aspiro l'aria e poi porto il cilindro a 400 gradi, succede che il legno si scinde in gas e cenere. Questo gas è del tutto simile a quello che usiamo per cucinare e può far andare un'auto, un generatore di corrente o scaldare.
Oggi esistono persino degli scooter che montano questo meccanismo.
La pirolisi, o scissione molecolare, è esattamente quello che abbiamo visto in Ritorno al futuro 2 quando fanno partire l'auto rovesciando in un cilindro un po' di immondizia.
È importante notare che con la pirolisi si può trasformare qualunque sostanza organica secca in gas.
E, per inciso, questo sistema è molto ma molto meno inquinante degli inceneritori (termovalorizzatori) che prima bruciano e poi filtrano i fumi (il che è difficilissimo e ti scappano le nano particelle mortali).

Ralph Baer, l’ideatore di Pong, sui quarant’anni di Magnavox Odyssey

via Downloadblog.it by Federico Moretti on 3/15/12

Magnavox Odyssey, la prima console per l'intrattenimento domestico, festeggerà quarant'anni dalla presentazione il prossimo 24 marzo. Ralph Baer, che la creò, ha compiuto novant'anni lo scorso 8 marzo. David Friedman, un fotografo newyorkese, ha intervistato l'ideatore di Pong, ovvero Table Tennis: il primo videogioco della storia.

Sorprendentemente, se a novant'anni ha ancora voglia d'innovare, Baer non è soddisfatto del ruolo assunto dai videogiochi. I giovani dedicano troppo tempo ai propri smartphone e non leggono più. In un certo senso, Baer riconosce d'aver creato un "mostro". Le sue intenzioni erano diverse: riunire le famiglie davanti alla televisione.

Table Tennis e gli altri undici giochi di Magnavox Odyssey, ad esempio, erano pensati per essere utilizzati in famiglia. Baer – considerato l'inventore dei videogiochi – non ne ha mai concepito un utilizzo individuale. Le modalità a single player di smartphone e console è «una degenerazione» d'un modello ideato per la condivisione.

Hands-on with wireless, ultrasonic stylus and touchless gestures at MWC (video)

via Engadget by Zachary Lutz on 3/1/12

This isn't the first time you've heard of EPOS or XTR, but it's been quite some time since we've checked in with either of the outfits. So, imagine our surprise as we stumbled on new developments from each company as we perused the Texas Instruments booth at MWC. In the case of EPOS, we're shown a stylus that, in addition to offering traditional physical touch input, also allows users to interact with a device via ultrasound. The system is built upon TI's OMAP4 platform and requires that four microphones be placed at the corners of the screen. In this demonstration, we're shown how users can manipulate objects on a 3D plane via the Z-axis by pulling the pen away from the display. Next, we're shown a new application for the touchless gesturing system that XTR first debuted back in 2010. In this scenario, it's demonstrated how tablet owners could use the front-facing camera (at merely QVGA resolution) to flip through pages of a cookbook without worry of getting ingredients on the device. The concept software was developed by a French outfit known as Stonetrip, and also allows users to zoom and pan through the pages. You'll find demonstrations of each technology in a video after the break.

Visualized: Nokia's 41-megapixel PureView sensor

via Engadget by James Trew on 2/29/12

If you thought a bigger pixel count just meant bigger file sizes, then take a look above. That big guy at the bottom is the 41-megapixel sensor responsible for those awesome Nokia 808 PureView shots we saw at MWC on Monday. The two above it are 8- and 5-megapixel sensors respectively, and give you an idea of the real-estate cost of packing a superior snapper. At two and a half times the physical size of the N8's prized optics, we think the PureView system earns its title as the biggest thing in mobile imaging somewhat convincingly.

Five Minutes Time Out Timer Stool From Wisteria

via Freshome.com - Interior Design & Architecture Newsletter by Ada Teicu on 2/8/12

Inspired by children's constant experimenting – when they either learn how to do or how not to do things – the Time Out Timer Stool was designed to help parents add a twist to those five minute time-outs. Every time the child needs to be punished, the hourglass -shaped Time Out Timer Stool can come in handy – just ask the child to sit on the stool until all the sand has poured down. This Wisteria exclusive product is available in navy or white and can be purchased for $69.00. Although an excellent idea, the Time Out Timer Stool can be expected to be delivered by mid-summer. Although this stool is not a toy and should be used only under adult supervision, the Time Out Timer Stool is practically a decorative item with functional features. Made out of mango wood, the hourglass stool has a vintage design and can hold up to 150 lbs. Each stool is filled with white sand to time approximately five minutes and help you in disciplining your child.
