Granted: 1997-10-14
Abstract: A drive system comprising an integrated gearhead motor system that produces relatively high torque output with minimal backlash. The present invention uses two axially mounted electric or air motors and gearhead assemblies integrated into a single unit. The two motor and gearhead assemblies are connected to concentric output drive shafts, and each output shaft mates to a respective gear of a split gear assembly. The split gear assembly is coupled to a drive shaft of a device that is to be driven by the system. A tachometer is coupled between the first motor and a position sensor iscoupled to the drive shaft of the device that is to be driven. The tachometer and position sensor are coupled to a controller that is used to control the respective torques provided by the two motors in response to rate and position signals provided thereby. By controlling the relative amount of torque provided by the two motors, the split gear assembly removes the backlash from the gearheads and gear interfaces to the drive shaft of the device that is to be driven. The present invention incorporates the two motors and two gearhead assemblies into a single assembly, reducing weight and space requirements. The design of the present invention also permits retrofitting of the drive system into existing single motor drive systems.

Title: Explicit synchronization for self-clocking glyph codes
Inventor: HECHT DAVID L
IPC: G06K1/12
Filed: 1994-10-27
Granted: 1999-03-16
Abstract: A self-clocking glyph code is composed of data glyphs which encode logically ordered data values, together with one or more multi-glyph synchronization code patterns. Each of the synchronization code patterns is distinguishable from the data glyphs, but the synchronization code pattern or patterns provide an explicit spatial reference for the data glyphs. To this end, the glyphs of the synchronization code pattern or patterns are written on the recording medium in accordance with the same spatial formatting rule as the data glyphs, plus at least one additional formatting rule that establishes a predetermined geometric relationship between the glyphs of the synchronization code pattern or patterns and corresponding ones of the spatially formatted data glyphs, such that the logical order of at least a significant number ( ~ 1) of the data glyphs is inferable from the synchronization code pattern or patterns. Preferably, each of the synchronization code patterns is composed of glyphs that are selected from the same finite symbol set as the data glyphs, so the synchronization code pattern or patterns typically are defined by glyph patterns that have a suitablyhigh statistical probability of being unique with respect to any pattern of dataglyphs.

Title: Current decay control in switched reluctance motor
Inventor: HORST GARY E
IPC: H02P25/08
Filed: 1995-06-06
Granted: 1999-06-08
Abstract: A control circuit (10) for controlling the residual or tail current decay in a single phase or polyphase SRM winding when a phase is switched from active to inactive.  A Hall-effect type sensor (30) senses rotor position of the SRM.  Current flows through a winding (W) of the motor when the motor phase winding is active; and, current flow into the winding decays to zero when the phase becomes inactive. Semiconductor switches (22) direct current flow into the winding when the phase is active and then redirect residual energy in the winding between an energy recovery circuit and an energy dissipation circuit when the phase becomes inactive.          A PWM signal generator (44) provides PWM operating signals to the switches to control current flow first into the winding and then between the recovery and dissipation circuits.  A control module (42), or microprocessor (52) with a PWM output, is responsive to rotor position information for controlling operation of the PWM signal generator.  The signal generator provides PWM signals having one set of signal characteristics when there is current flow to the winding and a different set of characteristics when there is not.          This produces alternate intervals of zero voltage and forced commutation residual current decay while the phase is inactive.          During the decay interval, both the PWM frequency and pulse duty cycle are variable to produce a current decay scheme which eliminates ringing and motor noise

Filed: 1995-07-14
Granted: 2005-10-04
Abstract: An information storage device randomly accesses data items in a sequential access storage medium. A controller, upon loading of the sequential access storage medium, causes the blocks of data items in the sequential access storage medium to be copied to corresponding blocks on the random access storage medium whose correspondence is established by the table. A table establishes the correspondence between blocks of data items in the random access storage medium and blocks of data items in the sequential access storage medium. Upon receiving an instruction from a host computer, the controller further performs a series of read/write operations on the blocks of data items in the random access storage medium. The overwritten blocks of data items on the random access storage medium are updated to the corresponding blocks on the sequential access storage medium.

Abstract: Verifying that a correct program is being received and displayed on a television set of a consumer. In addition, video quality is checked to assure that transmission has not degraded the video quality. When the consumer requests a program by transmission of a message via a controller in a set top box to a system computer controlling a cable television system, the system computer sends the necessary commands to cause the requested program to be communicated to the consumer site and also transmits to the controller in the set top box a start time of the requested program and information defining the initial video content of that program. At the start time, the controller verifies that the initial video content is being received and that the consumer has the set top box correctly tuned. The controller uses aframe grabber circuit at the consumer site to grab the initial portion of the program and then to analyze the stored portion with respect to the initial video content. If the stored portion is not the same as the initial video content, the controller transmits an error message to the system computer. In response to the error message, the system computer corrects the switching or transmission problem so that the correct program is being sent to the consumer site. The system computer then verifies that the correct program is being received.

Title: Attenuator for borehole acoustic waves
Inventor: HSU CHAUR-JIAN
IPC: G01S7/521
Filed: 1996-09-12
Granted: 2007-06-26
Abstract: ABSTRACT An attenuator for use in attenuating tube waves in a borehole includes a body formed from a permeable material having a rigid matrix which can be saturated with fluid. In its simplest form, the attenuator is one or more cylindrical bodies as part of a borehole acoustic logging system. Alternatively, the shape, particularly at the end regions, can be modified to reduce the amount of reflection of tube waves in the borehole. Another attenuator includes a body for placement in a borehole formed from an attenuating material, the shape of the body being selected such that the change in impedance experienced by acoustic waves in the borehole is gradual rather than abrupt. One particularly preferred shape for the body comprises one in which the diameter is greatest towards the center of the body, for example the shape formed by two cones placed base to base, or a cylinder having conically tapered ends. A number of bodies can be used where appropriate.
