Abstract: The output speed of a hydrostatic unit in a transmission is determined using a pair of variable reluctance sensors, one on a gear driven by the hydrostatic unit output and the other on the carrier of the planetary system. One of the two sensors will always be measuring a relatively high speed from which the hydro output is directly determined or indirectly determined using the current engine speed.  Thus the frequency of the speed sensor used to determine the hydrostatic unit output speed is not decreased at slow hydrostatic unit output speeds.

Abstract: A manhole restraining system used for venting out explosive gases in a manhole caused by an explosion. The manhole restraining system comprises a support frame, a two inch thick plate member positioned on top of the support frame, a plurality of restraining assemblies and a manhole cover for covering the manhole. The support frame and the plate member are embedded into a street and positioned above the manhole, where openings are aligned with the manhole. Three retaining assemblies are positioned on opposite sides of the manhole cover. Each retaining assembly includes a rod, a stop plate, a coil spring, a support plate and a nut. The rod extends downwardly through the dirt and the horizontal concrete base ledge, where the stop plate, the coil spring, the support plate and the nut are positioned and secured to the other end of the rod. A PVC pipe is provided with the rod for allowing the rod to move smoothly up and down without any friction. When an explosion occurs in the manhole, the pressure caused by the explosion lifts the plate member from a seated position on the main support frame above the manhole which in turn upwardly moves the rod, the stop plate, the coil spring, the support plate and the nut, where the explosive gases are vented out between the plate member and the main support frame. The stop plate, coil spring, the support plate and the nut absorb most of the energy caused by the explosion. The spring means soften the impact and assist in bringing the plate member back down to the main support frame in alignment with the manhole.

IPC: A61B5/296
Filed: 2000-07-07
Granted: 2010-04-27
Abstract: In a method and system for producing a higher quality electromyographic signal describing myoelectrical activity of an electrically active region of a subject's muscle, a plurality of EMG  signals representative of the electrical activity of the electrically active region of the subject's muscle are sensed through an array of electrodes. A weighting function is applied to the detected EMG signals to thereby produce weighted signals, this weighting function containing correction features for the relative locations of the center of the electrically active region and the electrodes. Finally, a sum or mean of a feature of the weighted signals is calculated to thereby produce the higher quality electromyographic signal.  Prior to calculating the sum or mean of the weighted signals, electromyographic quality of the weighted signals is evaluated, and the weighted signals or sum or mean of the weighted signals whose evaluated quality is insufficient are replaced. Alternatively, the higher quality electromyographic signal is replaced in response to weighted signals of insufficient quality. The method and system can also be used to determine signal strength or frequency contents of a signal falling outside the array of electrodes.
