Abstract: This disclosure is directed to a repeater (14) of a wireless communication system (6) that includes a positioning unit (4), such as a GPS receiver, in order to calculate the location of the repeater (14). In addition, various techniques are described that exploit the positioning information generated by the repeater (14) in order to improve the wireless communication system (6).

Abstract: A gun safety device for use with a firearm having a barrel and a chamber comprising a first tube with a wedge-shaped outer end and an internally threaded bore extending longitudinally within the first tube, a second tube with a wedge-shaped inner end structured for engagement with the wedge-shaped outer end of the first tube and a bore extending longitudinally within the length of the second tube and a rod translatable within the first and second tubes and including an externally threaded portion structured for mating engagement with the internally threaded bore of the first tube. The first and second tubes are structured for removable insertion into the barrel of the firearm so that the inner end of the first tube extends into the chamber of the firearm, the wedge-shaped outer end of the first tube and the wedge-shaped inner end of the second tube are positioned in the barrel and the flange is seated against the outer edge of the barrel.

Abstract: A process, preferably executed by software in a RAID mass storage system, involves seeking a transducer of an individual disk drive of the mass storage system to a predetermined write pre-seek location at which the next write operation is expected to be performed, and selecting the transducer of that individual disk drive by which to perform the next write operation. By pre-seeking to the write pre-seeking location and by selecting the transducer in advance of receiving the next write command, the time required for seeking to the write location and selecting the transducer becomes less of a restriction on system I/O throughput. Write pre-seeking is achieved by recognizing the execution of a predetermined write algorithm from at least one write operation. Recognition of the write algorithm allows the location for the next write operation to be predicted. Read pre-seeking is also used.
