Title: High-speed voltage sensing flip-flop with low setup time
Inventor: HUANG YI-REN
IPC: H03K19/003
Filed: 2001-02-23
Granted: 2002-03-11
Abstract: One of the embodiments of the high-speed voltage sensing flip-flop with low setup time of the present invention comprises a main latch and a slave latch. The main latch has a data input and a clock input. The slave latch receives two signal lines from the main latch. When the clock input is at a low potential, two input lines to the slave latch are pulled to a high potential, which makes two transistors conduct and pre-charge these inputs to the slave latch. When the clock is proceeded with a high conversion, the pull-up transistor of the main latch turns off, so that the inputs of the slave latch are separated from the outputs of the master latch. At this time, if the data input is at a high potential, the A-input to the slave latch will discharge. If the data input is at a low potential, the B-input to the slave latch will discharge. After the two inputs of the slave latch are separated from the main latch, since both input lines are not pulled high or low, any variation of the data input will make the inputs to the slave latch become a floating low potential. In this way, the inputs to the slave latch will be pre-charged/discharged during each clock cycle, whereby a setup time close to zero can be obtained by pre-charging.

Title: Method of calibrating a camera, method of determining a focal length of a camera, and camera control system
Inventor: TRAJKOVIC MIROSLAV
IPC: H04N5/232
Filed: 2001-04-04
Granted: 2002-10-11
Abstract: The calibration of a pan/tilt/zoom camera uses a template image that is known to correspond to the optical center of a larger image. A first image is captured, at the camera's maximum zoom setting, that contains a scene containing distinguishing details. After capturing this image, the camera is maintained at the same orientation, set to its minimum zoom setting, and a second image is captured. The first image is scaled down to form a template image, using the known ratio of a camera's minimum and maximum zoom capabilities. The location of this template image within the second image defines the optical center, or principal point, of the camera's image plane. Having determined the optical center of the camera's image plane, the focal length of the camera at various zoom settings can be determined by measuring the displacement of a template image at the optical center corresponding to a slight adjustment of the camera through a known angle at each of the various zoom settings. Conventional curve fitting techniques are used for determining an algorithmic mapping between zoom settings and corresponding lens powers. The use of a lens power measure facilitates a linear determination of the coefficients of the mapping equation, and provides an objective function that is less sensitive to inaccurate focal length determinations at low zoom settings.

IPC: B60K6/02
Filed: 2001-06-01
Granted: 2002-06-21
Abstract: The invention provides an engine power distribution apparatus in a parallel hybrid power system, in which the engine power distribution apparatus comprises an engine, an electric motor or an electric power generator, a first belt, a second belt, a third belt, and an electronic control unit. When the load imposed on the engine driving an output shaft is less than the set power created by the engine, the engine will distribute the excess power to the electric motor or the electric power generator for generating the electricity. However, when the load imposed on the engine driving the output shaft is more than the set power created by the engine, the engine can drive the output shaft with the assistance of the electric motor or the electric power generator. Thus, the total loading of the engine can be constant which also means the engine can be operated at a constant revolution speed and a constant torque output.

Title: Manufacturing method of fluoro based composite boards
Inventor: WANG SHIAN-YIH
IPC: C04B28/02
Filed: 2001-08-03
Granted: 2003-06-21
Abstract: In the manufacturing method of fluoro based polymer composite boards of the invention, which provides a fast process and high efficiency, a suitable amount of water soluble organic solvent is added to a fluoro based polymer suspension during the process of mixing ceramic powder and/or glass fiber to the fluoro based polymer suspension in order to improve the coagulation of the fluoro based polymer and ceramic powder, and to reduce the gelling time. During the process of mixing ceramic powder and/or glass fiber, the fluoro based polymer suspension and the organic solvent, a suitable amount of water can be added to control the ratio between the water and the organic solvent obtained from the mixture. The gelling time of the mixture can thus be reduced. By controlling the ratio between the water and the organic solvent obtained from the mixture, there is still enough time to allow homogeneous mixing after the gelling speed is increased.
