Title: Programmable automatic gain control according to transmission protocols
Inventor: TERRY JOHN DAVID
IPC: H03G3/30
Filed: 2004-11-24
Abstract: An automatic gain control (110, 245) provides for enhanced acquisition and tracking of wireless signals. The wireless signals may include signals using electrostatic fields, magnetic fields, or electromagnetic fields. In an embodiment, wireless signals are provided as radio frequency signals. The automatic gain control design is intended to quickly acquire new incoming information in a wireless signal. A control unit (130, 220) regulates the automatic gain control to manage the acquisition and gain of the wireless signal based on a transmission protocol. The automatic gain control adjusts the gain for the wireless signal to a minimal level required for detection for a preprogrammed amount of time, at the same time minimizing unwanted background noise from interfering with the wireless signal. When the communication session is concluded, the automatic gain control can be released allowing increased sensitivity in preparation of the next transmission.

Title: Information i/o method using dot pattern
Inventor: YOSHIDA KENJI
IPC: G06K7/10
Filed: 2004-12-24
Abstract: There is provided a dot pattern in which an x-direction shift and a y-direction shift are alternately generated for each adjacent information dot on a virtual grating line, so that the x-direction shift and the y-direction shift are alternately generated for each dot. Accordingly, every other information dots are arranged on the same grating line. For this, when reading by an optical read device, the search algorithm for the virtual grating line on the image memory is simplified, which in turn simplifies the search of the grating point on the image memory. As a result, it is possible to increase the dot pattern read speed without using a complicated program.

Title: Electric winding displacement detection method and apparatus
Inventor: JIANG QIAOSHU
IPC: G01M15/00
Filed: 2005-03-23
Abstract: A method and system for obtaining the characteristic impedance of an electrical winding by measuring the input and output voltages and the currents within a winding across a low frequency range, and applying transmission line properties to model the winding. The characteristic impedance (Zc) is directly proportional to the capacitance of the winding, and is independent of external circuits. Thus any changes to Zc will reflect movements of the winding that would affect the capacitance. Because Zc has a smooth and robust monotonical relationship with frequency of the applied signal, the resulting curve is exponential in shape. A relative comparison between Zc curves will provide a clear indication of the overall axial or radial winding movements, or winding faults, which can be used to assess the overall health of the winding.
