Title: Method for treating pathological conditions of tissues with non-coherent radiation and device therefor
Inventor: KLYACHKIN LEONID EFIMOVICH
IPC: H01L33/00
Filed: 1996-04-11
Granted: 2004-01-20
Abstract: The invention relates to medicine and is designed to treat diseases accompanied by metabolic disorder, weakening of enzymatic processes, regenerative function disorder of affected tissues. The method of treating pathological tissues with a noncoherent emission implies a periodic irradiation during 1-20 minutes with IR emission having the emission power density of 50-300 mW/cm2. The irradiation is repeated in one or two days depending on the time needed to stop the pain syndrome in the process of healing of pathological tissues. Th e proposed method implies that the irradiation is directed at the skin site directly over the organ responsible for the course of a disease caused by metabolic, enzymatic and regeneration process disorders in tissues, said irradiation being performed by an emission in the 1-56 .mu.m waveband in combination with line ar polarization and time modulation. The method uses a package of different wavelengths within a preset range with a linear polarization and time modulation introduced depending on the nature of disease. The emission power density is also selected depending on the nature of the disease. When an electric control signal is fed from additional power supplies of t he control system (2), the suggested device provides such parameters of the emission that permitto obtain the maximum curing effect. The emission source is pre-calibrated to provide a required emission power density. A broad band 28 semiconductor silicon light emitting diode (LED) based on a supershallow "p- n" transition with the waveband of noncoherent IR emission ranging from 1 to 56 .mu.m as the emitter. The power supply (1) is connected along the plane (a) of "p+n" or "n+p" transition to provide electric current inside the doped "p+n" or "n+p" region. The control system (2) is equipped with leads (c, d, e) for additional sources of electric field that are connected to the LED in such a way that the electric field is applied along the plane (a) of "p+n" transition providing a reverse and direct shift at the "p+n" transition. The control system (2) controls the spectrum range of the emitted light wavelengths, the degree of linear polarization and the frequency of time modulation. The control system (2) controls the LED by the electric field fed from the additional power supplie s through leads (c, d, e). The value of the electric field is selected dependi ng on the nature of the disease.

Title: Interference detection for spread spectrum systems
Inventor: CHEN GUANGZHI MICHAEL
IPC: H04B1/707
Filed: 1998-12-23
Granted: 2002-04-02
Abstract: In spread spectrum systems, such as CDMA-based systems, the presence of even narrow-band interference, such as that caused by jamming at a particular frequency, can adversely affect all of the current users in the system. According to the present invention, interference is detected and characterized by accumulating statistics for each energy spectrum in the system (e.g., for both the forward link band and the reverse link band in a telecommunication system). In particular, since a spread spectrum is ideally flat across the entire frequency band, narrow-band interference can be detected based on a significant deviation between the signal strength at any one frequency and the average signal level across the entire band. Similarly, wide-band interference can be detected based on the variance level over the entire frequency band. In a preferred embodiment, a pair of receivers are designed to perform background interference-detection processing for both the forward and reverse link.

Abstract: A system (10) for tightening a threaded fastener with a hydraulic wrench (14) has a pumping unit (12) which measures parameters representative of the torque applied to the fas-tener and the angle of advance of the fastener, remote from the wrench (14). The pump (12) measures pressure as a parameter representative of torque and measures pump speed as a param-eter representative of the angle of advance of the fastener. A ratchet-type hydraulic wrench is used, and the pressure versus angle data pro-duced in tightening a fastener is manipulated to discard irrelevant portions and smooth rele-vant portions to provide data representative of torque and angle during the tightening process from which to determine a final stopping parameter for terminating tightening. The system also has a calibration fixture (19) for determin-ing the volumetric rate of angle advance for a given wrench (14). Any tightening method-ology dependent upon angle may be used to practice the invention, or the invention may be applied to monitor the tightening process.

Granted: 2003-05-20
Abstract: An electrosurgical blade (100) is provided having a ceramic (104) coating which is conductive, flexible and provides a surface which inhibits the buil d up of charred tissue. These properties enable the electrosurgical blade to deliver controlled amounts of radio-frequency energy to tissue. The manufacturing process produces a coating of titanium nitride on a stainless steel blade which is amorphous, enabling the electrosurgical blade to bend with the blade in order to perform a wide variety of surgical procedures without damaging the coating. The electrosurgical blade can therefore be use d to efficiently cut, coagulate, fulgurate and desiccate tissue. While the bla de is primarily used in the monopolar mode, the present invention also encompasses at least two electrosurgical electrodes having the same ceramic coating as the electrosurgical blade, and used in the bipolar mode for coagulation.

Abstract: A system and method for dynamic priority conflict resolution in a multi-processor computer system having shared memory resources wherein a predetermined priority level for each input port (62) is maintained by each output port (64). When a conflict for a particular output port (64) occurs, the priority levels of the conflicting inputs are evaluated and access is initially granted to the highest priority input. Once this initial access is granted, the priority level of the "winning" input is then changed to the lowest priority level and the priority of all of the other inputs is increased by one. Inputs not requiring access to a particular output port (64) over a relatively long period of time will resultantly have their priority incremented to the highest level and remain there. If multiple inputs have been incremented to the highest priority, or another form of priority conflict occurs, the input may then default back to its original predetermined priority. In this instance, no input will be blocked indefinitely and the longest wait will then be equal to the time duration for which access is granted, multiplied by the total number of inputs.
