Abstract: PURPOSE: A location recognition apparatus capable of performing pan tilt is provided to detect the location of a user from two or more landmarks which are controlled by the pan/tile of an image photographing sensor. CONSTITUTION: A location recognition apparatus capable of performing pan tilt includes an image photographing sensor(10), a servo motor and a controller. The image photographing sensor takes a picture of the image. The servo motor tilts the image photographing sensor with the fan. The controller receives two landmarks from the image photographing sensor and operates the servo motor. The controller is fitted with the mobile unit in which it determines the current magnetism position on a real time.

Abstract: A device for controlling an induction motor is provided to operate a control device through a communication such as an Internet even in a remote location. In a device for controlling an induction motor, an encoder(700) is constructed to sense an operation of the induction motor. A DSP processor(100) and a memory unit(400) calculate a speed and a position of the induction motor and compare/process the calculated value with a predetermined reference value. A connector unit(200) is electrically connected to the DSP processor(100) to transmit the inner parameter of the induction motor. A pulse width converter is electrically connected to the DSP processor(100) to control the speed and the position of the induction motor through an inverter. And, a digital-analog converter(500) is electrically connected to the DSP processor(100) and the pulse width converter to transmit a digital calculation signal of the DSP processor(100) with an analog calculation signal.
