A slide type cellular phone having two separate bodies automatically or manually sliding with respect to each other includes a first main body having a motor with a shaft, an elastic member elastically supporting the motor, and a switch activating the motor, a power transmitting unit coupled to the shaft of the motor to receive a rotation power from the motor, a pinion coupled to the power transmitting unit to be rotated by the rotation power, a second main body slidably coupled to the first main body, having a rack coupled to the pinion, and sliding with respect to the first main body according to movements of the pinion and the rack, and a sliding detecting unit detecting a termination of a sliding operation of the second main body to control the motor. The pinion, the rack, and the power transmitting member to operates by a rotation of the motor to automatically or manually slide the second main body with respect to the first main body, thereby providing a more convenient cellular phone.

A motorized wheel-chair is equipped with one or more sensors for detecting obstacles. The detection method may be either radar or sonar (or both). An on-board computer processes these echoes and presents a visual or auditory display. With the benefit of these displays, the user issues voice commands (or exerts manual pressure) to maneuver appropriately the motorized wheelchair. One or more microphones pick up the sounds of the user's voice and transmit them to a computer. The computer decodes the maneuvering commands by speech-recognition techniques and transmits these commands to the wheelchair to effect the desired motion. In addition to speech recognition for decoding commands, voice (speaker) recognition is employed to determine authorized users.

A trash can include a sensor for detecting the presence of an object near a portion of the trash can. The detection of the object can be used to signal the trash can to open its lid. The trash can include an electronic drive unit for opening and closing the lid.

A braking system for a motor vehicle having braking wheels 16, 18, a service brake pedal, a friction braking system operative upon the braking wheels 16, 18 in response to actuation of the vehicle brake pedal 26, an anti-lock braking system cooperative with the friction braking system to control the friction braking force applied to the braking wheels 16, 18 upon detection of slippage of the braking wheels 16, 18, a regenerative braking system operative upon the braking wheels 16, 18 in response to actuation of the vehicle brake pedal 26 for selectively generating an applied regenerative braking force through the braking wheels 16, 18, and an ambient temperature sensor 52. The regenerative braking system operates at a first effective rate of applied regenerative braking force upon application of the brake pedal 26 at an ambient temperature above a desired temperature, and the regenerative braking system operates at a second, lower effective rate of applied regenerative braking force at an ambient temperature below a desired temperature. Upon activation of the anti-lock braking system, the applied regenerative braking force is reduced at a first predetermined rate when the ambient temperature is above a desired temperature and the regenerative braking force is reduced at a second, faster predetermined rate when the ambient temperature is below a desired temperature.
