Title: Single and multiple channel block adaptive methods and apparatus for active sound and vibration control
Inventor: SHEN QUN
IPC: H04B1/12
Filed: 1994-04-28
Granted: 2000-02-01
Abstract: A method and apparatus is described for actively canceling a primary noise source to produce a desired noise level at at least one location. The apparatus comprises a signal processor which drives at least one actuator (H'), et least one error sensor (e(k)) and a primary noise reference signal (x(k)). The error sensors are positioned proximate to each of the locations. The output of the error sensors and primary noise reference signal are sent to the signal processor (312). The relationship between the driving output of the processor and the output of the error sensors is modeled by a block of filter coefficients (314). Based upon the model and the primary noise reference signal, the processor drives the actuator to generate a canceling noise at the location. The processor calculates differences between the desired noise level and the output of the sensors. A variable convergence factor and a gradient block are derived from the residual noise and are used to adapt the filter coefficients.

Granted: 1999-02-23
Abstract: A light system includes a laser light generator and an array of motor-driven mirrors aligned to deflect a beam of laser light in various directions to create a light show.   The motors are operated in a controlled sequence by a motor controller.   The motors are small d.c. permanent magnet motors which are driven from a d.c.  source whose voltage  is  adjustable  to vary the frequency of oscillation of the motors and, hence the mirrors.          Connected to each motor is a small coil spring whose coil is carried on the motor shaft and which has two extended arms, one of which is secured to a nearby stationary member and one which is secured to the mirror shaft.   The mirror shaft is movable between two stops.   The spring acts to oppose the direction of motion of the motor such that the motor is normally stalled out and driven back to one of the stops before it can be moved  far enough to impact the other stop.

Abstract: A control arrangement for minimizing optical leakage in a time-division, multi-stage electro-optical switch by the periodic adjustment of switching voltage levels.  An optical detector connected to an idle port of the switch transmits a leakage signal which represents optical leakage in the switch in various configurations of the switch.  The leakage signal is filtered by a low pass filter and sampled at a low rate. A processor stores the sampled data and periodically analyzes the data to determine the appropriate changes in the switching voltage levels for each of the stages of the switch to minimize optical leakage.  An output circuit connected to the processor and the switch modifies a previously determined base voltage signal for each of the stages to incorporate the voltage level changes and applies the modified signals to the switch in the appropriate time slots.

Filed: 1997-06-27
Granted: 2006-02-07
Abstract: The present invention provides a directory service system for accessing a plurality of directory services in a uniform manner. Each directory service manages information relating to objects of that directory service. The type of information that a directory service manages for an object is defined by the object class of the object. An object class defines the properties (i.e., information) that a directory service manages for objects of that object class. Each property has a property name and property type. A directory service has a property value for each property defined by the object class of each object. The directory service system comprises a schema browsing component, a name resolving component, a binding component, and an extending component. The schema browsing component controls the retrieving of the property name and property type of each property of each object class of each directory service. A client of the directory service system uses the schema browsing component to retrieve property names and property types of the object classes. The name resolving component controls the receiving of a unique identifier of an object within a directory service and the locating of the object within the directory service. The binding component controls the binding to an in-memory object representing a located object within a directory service. The extending component controls the defining of new object classes and new properties for each directory service. A client of the directory service system uses the extending component to define new object classes and new properties.

Granted: 2003-11-18
Abstract: A threaded pipe connection is disclosed for connecting two joints of pipe having externally threaded pin members, one pin member having external right-hand threads and the other pin member having left-hand threads.  An internally threaded coupling having right and left-hand threads that mates with the threads on the pin members.  An internal pressure seal ring is positioned to provide a seal between the ends of the pin members.  A plurality of mating lugs and grooves on the ends of the pin members hold the pins from relative rotation when the connection is being made up.  A metal-to-metal seal located between each pin member and the coupling adjacent each end of the coupling isolates the threads of the connection from the ambient environment thus sealing off the pipe annulus from external pressure due to hydrostatic head.  Indicia such as engaging surfaces or aligned scribe lines on the pin members ensure that the sealing surfaces on the coupling and the pin members that form the external seals are positioned to properly engage and form seals when the connection is made up.

Title: Solid-state relay
Inventor: HAYASAKI YOSHIKI
IPC: H01L27/12
Filed: 1998-06-26
Granted: 2001-08-28
Abstract: A solid state relay composed of a series connected pair of LDMOSFETs has a minimized output capacitance. Each LDMOSFET is configured to have a silicon layer of a first conductive type, a drain region of the first conductive type diffused in the top surface of the silicon layer, a well region of a second conductive type diffused in the silicon layer in a laterally spaced relation from the drain region, and a source region of the first conductive type diffused within the well region to define a channel extending between the source region and a confronting edge of the well region along the top surface of the silicon layer. Each LDMOSFET is of an SOI (Silicon-On-Insulator) structure composed of a silicon substrate placed on a supporting plate, a buried oxide layer on the silicon substrate, and the silicon layer on the buried oxide layer. The well region is diffused over the full depth of the silicon layer to have its bottom in contact with the buried oxide layer, so that the well region forms with the silicon layer a P-N interface only at a small area adjacent the channel. Because of this reduced P-N interface and also because of the buried oxide layer exhibiting a much lower capacitance than the silicon layer, it is possible to greatly reduce a drain-source capacitance for minimizing the output capacitance of the relay in the non-conductive condition.
