Patent number: 7232131Abstract: A displacement apparatus is provide for skating footwear such as in-line roller skates. The displacement apparatus has extension triggers, each of which is connected to respective rod members that releasably retain the rollers in a retracted position, and a retraction trigger connected to a slidable rod member that releasably retains the rollers in an extended position. Manual operation of the extension triggers and retraction trigger allows extension or retraction of the in line rollers as required. When retracted, the rollers are conveniently housed within a cavity in the underside of the shoe to thereby allow normal walking.Type: GrantFiled: October 7, 2002Date of Patent: June 19, 2007Assignee: Australian Retractable Blades Pty LtdInventor: Malcolm Paul Hurst

Patent number: 4847868Abstract: The present invention is directed to a digital non-coherent pattern detection scheme in which spectral analysis of phase encoded signals is utilized to provide pattern recognition. The present invention is relatively insensitive to the power level of incoming signals. Since the power level is easily detected and determined, the present invention allows the various algorithms to operate quickly. Further, utilizing the magnitude samples of the incoming signal result in a pattern detection scheme that is independent of modulation technique. The present invention utilizes the concept of spectral analysis to determine spectral lines which are present in phase encoded signals. A phase encoded signal such as a DPSK or QAM having an implicit pattern contained therein, which results in unique spectral lines. By detecting the spectral lines in certain combinations, the phase encoded pattern being sent may be identified.Type: GrantFiled: February 22, 1988Date of Patent: July 11, 1989Assignee: Silicon Systems, Inc.Inventors: Dave Hedberg, Paul Hurst, Steve Levy

Patent number: 4789995Abstract: A synchronous timer anti-alias filter gain stage utilizing switched capacitor circuitry is described. A high frequency sampling clock is used for a switched capacitor anti-alias filter. In the preferred embodiment, a clock of approximately 921.6 kilohertz is utilized. This fast clock is divided down by a programmable timer into a low frequency sampling clock to drive a signal gain stage. The programmable divide values are integers so that the anti-alias filter clock and gain stage clock are in an integer relationship with each other for edge locking. The high frequency clock is divided down by a fixed divider to provide a clocking signal to an input band pass filter. The fixed divide value is also an integer so that the band pass filter clock and anti-alias filter clock are in integer relationship with each other. Switched capacitor anti-alias filters are used in place of continuous time, R-C anti-alias filters.Type: GrantFiled: May 1, 1987Date of Patent: December 6, 1988Assignee: Silicon Systems Inc.Inventor: Paul Hurst

Patent number: 4777453Abstract: A switched capacitor circuit implements a base band, finite impulse response filter (BBF) and balanced modulator with a single operational amplifier. The analog modulator has particular application in voice band modem applications and requires little or no microprocessor code space. Simplified sine and cosine functions are implemented in a pair of base band filters such that the output of only one base band filter is required at any one time. In this manner, a single operational amplifier may be utilized to implement the analog modulator/base band filter of the present invention. The use of switched capacitor technology and a single operational amplifier results in less silicon area dedicated to the analog modulator than for corresponding digital modulators.Type: GrantFiled: May 1, 1987Date of Patent: October 11, 1988Assignee: Silicon Systems Inc.Inventors: Paul Hurst, Kiyoshi Fukahori
