Abstract: The invention relates to an improved retaining and release mechanism for the magazines of automatic and/or semi-automatic firearms. A tooth (52) of lever (54) is designed to engage lateral securing slot (34) of magazine (30). The lever (54) is urged towards a body (16) of the firearm by energy exerted through a plunger (82) from a plunger spring (80) contained within the shaft (36). A base (38) is attached to the spring loaded shaft (36) located transversely in body (16) of the firearm and attached at its opposite end to an operating pushbutton (44). The tooth (52) can be disengaged from the lateral securing slot (34) by depressing either operating pushbutton (44) or slide (62). The invention's ambidextrous function can be engaged or disengaged by extending or retracting, respectively, slide (62) over locking shelves (70a, 70b). The magazine (30) can thus be released from both sides of the rifle.

IPC: H04L12/56
Filed: 1998-02-03
Granted: 2002-03-26
Abstract: Prior scheduling and assignment methods stress equal utilization of each of the processors in a system. These methods tacitly assume that each of the processors of each of these systems are equal in capabilities, an assumption that neglects the fact that as newer processors are added to a system to increase capabilities, the newer processors often are faster and have greater throughput than the system's existing processors. On such a system that has diverse processors, a equal utilization scheduling and assignment method protects the slower processors from overload while under utilizing the increased capabilities of the system's newer processors. Systems with diverse processors can utilize the increased capabilities of the faster processors by a method of calculating and assigning a request for service to the fastest processor that is able to respond.

Abstract: A radiation field analyzer (10) provides means for analyzing the spatial mode spectrum of radiation received from a scene. In a multimode waveguide embodiment, light from a laser (24) is directed towards a scene through an alumina waveguide structure (12). A portion of the laser light is directed towards a mode generator (28) which selectively converts the laser radiation into one of a series of modes. Laser light returning from the scene is mixed with the light from the mode generator to produce interference signals. These signals are measured by a detector (34) and analysed by a programmed computer (36). By sequentially altering the mode generated by the generator (28) and analyzing the resulting signals, a spectrum of the modes returning from the scene is obtained.

Granted: 2005-01-04
Abstract: A winding fault detection system provides classification and identification of winding faults or winding malfunctions. The fault detection system provides signals to individual electronic switches for segmented primary windings each having an electrical phase and grouped into sub-phases which are individually switch into or out of an excitation supply or isolated through the electronic switching in response to signals from the winding fault detection system. Each primary winding forms an electrical member which includes a stator having a poly-phase winding, and there is a secondary electrical member magnetically coupled with the stator. Each primary has magnetic field sensors which detect phase angle and magnitudes of radial components of air gap flux by magnetic measurement probes between each secondary electrical member and each primary electrical member and derives an electrical signal for a component of air gap flux contributing to electromagnetic torque at each position of each stator's periphery. Additionally, the system instantaneously stores data continuously derived from the magnetic sensors and determines a hierarchy of fault detection schemes.
