A group of MIT engineering students wants you to get nice and comfy. They've created a thermoelectric bracelet designed to keep its wearer at the optimal thermal level for personal comfort.
Called Wristify, the prototype monitors air and skin temperature and then shoots thermal pulses into the wrist to cool or warm the user according to their needs. Very small, quick changes in temperature on parts of the skin with high blood flow can make the whole body feel several degrees cooler or warmer, the creators say, and their watch-like thermal system can change the body's temperature by up to 0.4 degrees Celsius per second.
The intent is to save energy by controlling the temperature of an individual person, rather than an entire building, a goal that anyone who's ever turned on a personal space heater in a frigid office building in July can get behind. The team just won $10,000 from MIT's Making And Designing Materials Engineering Competition, which the inventors will use to improve the prototype and the algorithms that automate the pulses.
With any luck, this will not put us BAS guys out of business...
- Stand-alone or with multiple units, controls VFDs or across the line fans directly
- LCD display with intuitive set up menu
- Integrated set-point relay and alarm relays
Applications-Ensure adequate air flow in parking lots & garages
-Control VFDs or across the line fans directly
Senva CO Series carbon monoxide sensors maximize energy savings, while ensuring optimal ventilation. These sensors measure and control the amount of CO present in a location. The unit can act as stand alone controller with either relay output for DOL fan operation or 0 to 10VDC or 4 to20mA outputs for directly controlling variable speed fans. Multiple sensors may be used in parallel sequence (0-10V) for cost effective coverage of large areas.
- Integrated display and push-button menus for field selectable scale, calibration, and operational modes
- Dual 4-20mA and 0-5V/0-10V output (jumper selectable) for direct control of variable frequency or as input to other controllers
- Integrated set-point relay is ideal for direct control applications of DOL fans
- 0-10VDC output is internally equipped for parallel connection of multiple sensor voltage outputs for large area coverage. Resulting voltage will be the greater of all connected sensors. Cost-effectively sensing and control of large areas.
