Abstract: An apparatus for cooling a compact disc includes an actuator for rotating the compact disc. An air-moving device is driven by the actuator and moves air about the compact disc.

Abstract: A telematics device (10) for an automotive vehicle has an interface capability with a TDD (36) to provide abilities to transmit and receive TDD data only calls, Voice Carry Over calls and Hearing Carry Over calls.

Abstract: A mechanical clock arrangement includes a linkage apparatus rotatingly driving an hour hand and/or a minute hand of a mechanical clock. A sensing device senses a time of day displayed by the mechanical clock. A control device is in communication with both the sensing device and a source of an actual time of day. The control device actuates the linkage apparatus to thereby cause the time of day displayed by the mechanical clock to correspond to the actual time of day.

Abstract: An improved method of detecting the presence of an obstacle in the path of a motor-driven panel by computing the slope of a measured motor speed signal in a way that cancels the effect of periodic undulation of the speed signal, and comparing the computed slope to a slope threshold that is selected as a function of the average motor speed. A position sensor produces a series of pulses corresponding to panel movement, and a microprocessor-based controller stores an array of speed-related samples corresponding to the time periods between successively produced sensor pulses. The average speed is computed at two different points in the array, and the slope of the stored speed samples is determined according to a difference between the computed average speeds.
