摘要:
Disclosed herein is a technology for controlling speed of a car. More specifically, the invention relates to a speed controller for a car using telematics, the controller comprising a sensor unit to detect the speed of the car, the distance from the car to an object in front, and the operating status of a brake pedal and an accelerator pedal, a telematics system to output a signal to control the travel speed of the car and a gear shifting signal, when the speed of the car and the distance from the car to the object in front exceeds a preset range of an approaching distance, a speed regulation system to maintain the travel speed of the car within a speed limit by controlling an accelerator pedal and a brake pedal control unit, and an automatic transmission system to set a gear shifting level by controlling a gear shifting lever control unit.

A mode conversion method for performing an input/output of the control data in a multifunctional programmable remote controller having multi-band remote function and learning functions, including the steps of checking for which key is selected among a mode key, a set key, and normal keys, converting to a waiting mode when the setting is not in progress if a key signal is not input, and displaying the selected mode within a certain time and converting to a using mode when the setting is in progress, then, inspecting the setting condition if the mode key is selected so that if the setting is not in progress, each mode display is toggled to indicate that the mode is converted, and if the setting is in progress, the current step returns to a key scanning step for determining whether the current mode is a using mode or a setting mode so that if it is the using mode, data is output and displayed by modes and if it is the setting mode, the mode is selected.

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.

A key scan circuit and the method thereof in a microcomputer is disclosed which requires no diode for preventing circuit short and performs key check or automatic operations with a simplified circuit structure. The key scan method includes a step of designating the input/output mode of a bilateral port by a data direction register in a microcomputer which includes an input/output bilateral port and an input only unilateral port, so as to prevent circuit shorts when more than one key are pushed. Further, by using first and second memories, the key scan method includes a step of determining whether the number of logic low states in the first memory is greater than one, and determining whether the number of logic high states stored in the second memory is greater than one, thus indicating the pressing of multiple keys. Then, the pushed key's value is determined by a predetermined formula by obtaining the value m when the mth bit value of the first memory is logic low, and the value n when the nth bit value of the second memory is logic high.

Disclosed is a touch screen panel including a plurality of separate sensing electrodes, and a plurality of separate driving electrodes. Each of the sensing electrodes includes a main electrode and a plurality of expanded parts. Each of the expanded parts includes a sub-electrode extending from the main electrode and at least one expanded electrode extending from the sub-electrode. Each of the driving electrodes surrounds at least part of a corresponding one of the expanded parts.
