Abstract: PURPOSE: A specific area extraction method is provided to enhance a success rate of extracting a feature pattern of a target object, which can be variously expressed according to the image process method, by applying one extraction scheme in a case that other extraction scheme fails in the feature pattern extraction. CONSTITUTION: The method comprises several steps. A system sets various feature patterns expressed in a binary image according to an image process of a target object(S110). If an image of a target object is taken by a camera and input, the system performs a preprocess on the input image(S120). The preprocessed input image is converted into a binary image(S130). Then, the system checks whether the preset feature patterns exist at the converted binary image(S140), and if they exist, the system determines a specific area of the target object at the input image(S150).

Title: Method and apparatus for predictably switching diversity antennas on signal dropout
IPC: H04B7/08
Filed: 2000-05-01
Abstract: A low-cost diversity antenna switching system and method is realized by controlling bias voltages on PIN diodes. By increasing the reverse bias voltage impressed upon a PIN diode, an RF signal impressed upon the diode is increasingly attenuated. As the PIN diode is forward biased to conduct in the forward direction, RF attenuation decreases. Two or more PIN diodes are used to increasingly attenuate signals from one antenna as attenuation of signals from another antenna is gradually decreased. The progression of the bias voltages is accomplished using a microprocessor that monitors a received signal strength indicator (RSSI) signal from a radio receiver. The RSSI is used to control which of two antennas are coupled into the receiver by predicting a signal fade.
