Abstract:
In a semiconductor device and a method of manufacturing the semiconductor device, a plug and a channel structure are formed. The plug fills an opening and the channel structure extends upwardly from the plug. The channel structure has a substantially vertical sidewall. The opening is formed through an insulation structure located on a substrate. The plug and the channel structure comprise a material in a single crystalline state that is changed from an amorphous state by an irradiation of a laser beam. The channel structure is doped with impurities such as boron, phosphorus or arsenic.
Abstract:
Semiconductor devices are provided having a selective epitaxial growth layer that exhibits suppressed lateral growth. These semiconductor devices may include a semiconductor substrate having a silicon region, and an epitaxial growth layer formed on the silicon region. The epitaxial growth layer may comprise alternatively stacked silicon and silicon germanium epitaxial layers. The silicon germanium epitaxial layer may be thinner than the silicon epitaxial layers.
Abstract:
Disclosed herein is a backward control system for an automobile using telematics. The system includes: a sensor unit to sense a backward speed, presence of a backward object, and the operating state of the brake pedal and the accelerator pedal of an automobile when backward-travelling; a telematics system unit to output a control signal, when a distance between the automobile and the object is within a pre-set range in response to the signal from the sensor unit, such that the backward-travelling is automatically interrupted to thereby prevent collision with the object; and a accelerator pedal control unit and a brake pedal control unit to automatically control the operation of the accelerator pedal and the brake pedal to thereby interrupt the backward-travelling in response to the control signal outputted from the telematics system unit.
Abstract:
Partial body-weight support systems and methods for human gait training are disclosed. The system may include a motor and a cord coupled to the motor, the cord and the motor providing at least partial body-weight support to a user during human gait training. The system may also include a controller that actively adjusts the operation of the motor based upon measured gait parameters. The method may include coupling a human to a motor and monitoring the gait of the human while the human is walking to produce a signal indicative of the gait of the human. The method may also include varying the operation of the motor based on the signal so as to assist the human in attaining a predetermined gait pattern.
Abstract:
A method, system and apparatus for restricting, within a specific area, the photographing function of a camera mounted in a mobile terminal. A control signal is transmitted to a mobile terminal within a photograph-prohibited area and the mobile terminal disables the camera. Upon leaving the photograph-prohibited area, the camera is enabled.
