Portable device for time measurement that counts with the basic functions of time and date, alarm, Timer, Stopwatch, Fixed Interval Timer function, as well as a Variable Interval Timer function. The receiving unit is for receiving an RF signal to generate a set of discrete signals. A first processor provides an output indicating a desired level of force to be applied to the seat-belt determined from the steering angle and the velocity of the vehicle. When the back-end server processes the request, the requested content may include one or more protocol specific resource identifiers. In some embodiments, the opening is configured to allow a biological sample to be introduced into the semiconductor device.
