bitbloq Patent US6142953 - Respiratory inductive plethysmography band transducer - Google Patents 1. Field of the Invention The present invention relates to a device for measuring of expansion and contraction in general and particularly monitoring for the respiration of patients by moving coils producing a mutual induction for modulating a carrier signal. 2. Description of the Related Art Many devices measure the respiration of patients. Other methods of monitoring breathing include the measurement of thoracic impedance with the use of electrodes placed on the patient. Another method of monitoring a patient's breathing is by measuring the patient's torso to detect expansion and contraction, which is directly proportional to the volume and rate of inhaling and exhaling. The mutual inductance signals can be measured easier if the relative movement between the coiled wires is greater. A problem in the prior art is that the belts attached around the patient frequently slip or shift changing the diameter of the belt and thereby changing the signals received from the belt.
Snap4Arduino beta GNU/Linux You just need to unpack the package. The executable is Snap4Arduino. In case it complains about a missing library, you can sudo run the postinstall.sh script, which will attempt to automatically take care of the issue. If you would like to help us build packages for different distros, please don't hesitate to write to us. MacOS X Unzip the package and run the Snap4Arduino package. Microsoft Windows Just unzip the package and run the installer. Chromebook Extract the experimental Chromebook package, a file called Snap4Arduino-chrome.crx will pop up Point your Chrome to (paste this in your address bar) Drag and drop the Snap4Arduino-chrome.crx file from your file system into your Chrome, into the tab Chrome will tell you the extension needs you ti give it permissions. Other systems The experimental Chrome app will (mostly) work on any other system.
Atlas: The First Fitness Tracker that Actually Tracks Your Workout Thank you to the 3,943 backers who made Atlas Wearables what it is today! Jump to: Overview | Technology | How It Works | Creation Process | Perks | Team Current fitness trackers are just glorified pedometers. Steps are important but they’re only a single metric of your fitness. Atlas is a wearable device that tracks and identifies your different activities, evaluates your form, counts your reps and sets and calculates the calories you burned. With a single on-wrist device, Atlas can track your body on the x-, y- and z-axes. With Atlas, there’s no need to take your phone to the gym anymore. You can use that real-time feedback to instantly see your progress and keep track of how many miles you ran, how many laps you swam and how much weight you benched. Atlas can also learn new exercises you teach it. Jump to: Overview | Technology | How It Works | Creation Process | Perks | Team The technology inside Atlas adds an incredible amount of context to your workout. What is the warranty? U.S.
miniBloq Smart Clothes—A Wearable Air Quality Sensor Caption: The prize winning pollution sensorCredit: Conscious Clothing America is waking up to the importance of a healthy lifestyle. But while what you eat is important, what you breathe in matters, too. To address these questions, NIH, with the Department of Health and Human Services (our parent agency) and the Environmental Protection Agency, issued a challenge: the “My Air, My Health” challenge. Applicants designed wearable, real-time, location-specific air pollution sensors that measure and link to an individual’s physiological data—including how deep your breathing is—and then transmit the info to a central data repository. Caption: Close-up of the sensor. Conscious Clothing, the group that created the sensor you see in the pictures, won the $100,000 grand prize—which was presented to them at the recent Health Datapalooza here in Washington, D.C.

Sin embargo, cada kit de robótica tiene su manera particular de programarse y no permite la comunicación con otros kits. Es por esta razón que se decidió crear Physical Etoys, una extensión argentina de Etoys que facilita la interacción con estos dispositivos. “La computadora es un instrumento cuya música son las ideas” Alan Kay Descripción general del proyecto Physical Etoys es un ambiente de programación visual de robots gratuito, de código abierto y multiplataforma que conecta el mundo virtual de las computadoras con el mundo real en que vivimos. Resultados deseados Facilitar la programación de material concreto así como también su enseñanza.Integrar los kits más populares de robótica educativa en un solo ambiente extensible.Fomentar el pensamiento computacional.

Sensors | 60210-B • Electronic Media Studio 2 A sensor is a device that measures a physical quantity and converts it into an electric signal. They can be analog (working like potentiometers) or digital (working like switches). Some examples of analog sensors. Testing a sensor To see if a sensor works we can read its analog value to control an analog output: an LED in Pulse Width Modulation (PWM) variable brightness. We send the value to serial as well (open the serial monitor). You can connect a piezo speaker to have an audio feedback (+pin to ~9 on the Arduino, -pin to ground). Force sensitive resistor Flex sensor This works in a similar way. Photoresistor Photocell are basically resistors that change its resistive value (in ohms Ω) depending on how much light is shining onto the squiggly face. Stretch Sensor A piece of conductive rubber cord whose resistance chances according to the stretch ratio. It actually looks more like this This code is calibrated for the circuit above, a piece of cord of about 3 inches + a 10Kohm resistor.
