Noise Induced Hearing Loss (NIHL)

Sensear Pty Ltd, an Australian company that owns innovative technology enabling speech communication to be heard in high noise environments, without the need to remove hearing protection. This is a significant advance on present day technologies as Sensear's technology remains effective in environments above 85 dB(A).
Significantly, this innovation is the latest and most effective technological advance in the fight to eliminate Noise Induced Hearing Loss (NIHL), recently identified as the world's most common occupational health and safety issue.
In addition to the technology's preventative attributes, it also improves quality of life for those people already afflicted with NIHL, through its ability to variably enhance the speech signal they receive in noisy work or social environments.
Sensear technology has a number of applications including industrial, commercial and social.
"Anyone wanting to hear speech safely and clearly in a high noise environment needs Sensear"

The Emotional-Social Intelligence Prosthesis

Technology does not naturally sense nonverbal cues such as facial expressions and tone of voice, and does not easily acquire common-sense knowledge about people. These "mind-reading" functions also do not come naturally for some people, such as those diagnosed with autism. ESP is an affective wearable system that explores ways to augment and enhance the wearer's emotional-social intelligence. ESP's computational model of mind-reading infers affective-cognitive mental states from head and facial displays of people in real time, and communicates these inferences to the wearer via visual, sound, and tactile feedback. Our work leverages the advances in affect sensing and perception to (1) develop technologies that are sensitive to people's affective-cognitive states; (2) advance autism research; and (3) create new technologies that enable people to enhance their social-emotional intelligence.

Eyeglasses HMD

Japan's Scalar Corp. has been developing a lightweight, practical HMD for some time now and with the recently introduced Teleglass T3-F Video Eyeglasses, they have hit the bullseye - pardon the painful pun. Weighing just 35 grams (or just over an ounce), the T3-F dispenses with the Cyborg look that has graced - maybe dis-graced is a better term - previous HMDs and prevented users from doing anything other than watching the video display. Users enjoy the feeling of watching a 28" video screen from a distance of about 6 feet away. Teleglass T3-F Video Eyeglasses solve that issue by only displaying the video to only one eye, leaving the other free to look out for your mother-in-law at the airport arrival lounge, scan for oncoming traffic or watch for the right subway stop.
It's the latter attribute that Scalar's ad people have been focusing on. According to Taizo Kiyohara, General Manager of Scalar's Technical Development Division, "Many Japanese workers spend a long time in 'commuting hell' on a crowded train every day. Our HMD can change the hell into heaven." Suggested uses for the T3-F are watching movies, taking foreign language lessons or boning up on technical manuals. Students will be able to put formerly wasted time to use studying, provided they can find the right video content for their studies.
Products like the Teleglass T3-F Video Eyeglasses will likely find growing appeal in the US as carpooling, public transit and business air travel becomes more prevalent - and time consuming. As for the still somewhat robotic appearance of a device sprouting from an eyeglass lens, if we got used to Bluetooth receivers, we can get used to anything. Teleglass T3-F Video Eyeglasses have been available in Japan since late May of 2007 direct from Scalar Corp. or online at the Tsukumo Co. Ltd. website for approximately 98,000 Yen (about $825).

Arduino - queimar chip atmega


Queimar chip atmega e testar a arduino automatizada e no PD (programa)

























Arduino - verificar circuitos

Após retirar, com bom bril, a tinta da caneta, que protege o circuito, verificar se há curto e se a corrente passa por ele sem interrupção, marcar possíveis falhas para corrigir posteriormente. Na hora de desenhar o circuito, deve ser bem traçado, para evitar problemas impossíveis de consertar depois.

Arduino - retirar a tinta que protegeu o circuito de cobre






Usar bom bril para retirar a tinta que protege o circuito na placa, durante a retirada do cobre, com sulfato ferroso.

Arduino - imprimir o circuito na placa






Na placa imprime-se o circuito, silkscreen. Depois, sobre toda a impressão, traça-se com caneta o desenho de novo, antes de fazer o banho com sulfato ferroso, que retira todo o cobre sem proteção.que não está coberto pela tinta.

Arduino - retirar o cobre da placa


Usar luvas, mergulhar a placa, com o circuito impresso por silkscreen, em sulfato ferroso, agitando sem parar, durante aproximadamente 15 minutos. Verificar a reação química, o cobre da placa se dissolve, exceto onde está impresso o circuito, que foi protegido com caneta própria, resistente ao produto; retirar a placa com luvas, quando não houver mais cobre, lavar em água corrente. Esse processo deve ser feito ao ar livre ou lugar bem ventilado.

What is Arduino?
Arduino is an open-source physical computing platform based on a simple i/o board, and a development environment for writing Arduino software. The Arduino programming language is an implementation of the language used by http://wiring.org.co/, while the Arduino environment is based on http://www.processing.org/.


Arduino can be used to develop interactive objects, taking inputs from a variety of switches or sensors, and controlling a variety of lights, motors, and other outputs. Arduino projects can be stand-alone, or they can be communicate with software running on your computer (e.g. Flash, Processing, MaxMSP.) The boards can be assembled by hand http://www.arduino.cc/en/Main/USBAssembly or purchased http://www.arduino.cc/en/Main/Buy preassembled; the open-source IDE can be downloaded http://www.arduino.cc/en/Main/Software for free.


Arduino received an Honory Mention in the Digital Communities section of the 2006 Ars Electronica Prix. Credits http://www.arduino.cc/en/Main/Credits
