Title: Methods and apparatus for signal searching using correlation
Inventor: WANG RUI R
IPC: H04B1/707
Filed: 1999-12-17
Abstract: A signal searcher for a CDMA communications system has a reference signal generator and a correlator to correlate a reference signal with a received signal in short (signal-coherent) correlation intervals. The code phase of the reference signal is changed through all of N possible code phases in N  successive correlation intervals constituting one signal scan cycle. The correlation results for the same code phase for a plurality of the correlation intervals are accumulated over successive signal scan cycles using a combiner and buffer, and the presence and code phase of one or more desired signals in the received signal are determined by a decision unit in dependence upon the accumulated correlation results. In one embodiment all of the correlation results are accumulated; in other embodiments memory requirements are reduced by accumulating only larger values of the correlation results.

Abstract: A door operator and related method of setting custom limits on movable barrier travel, includes a motor for moving the movable barrier between two travel limit positions, an operator for controlling operation of the motor, and a disconnect system coupled between the motor and the operator. The disconnect system is switchable between a connected position and a disconnected position, wherein the motor can engage the operator only when the disconnect system is in the connected position. The operator is connected to a potentiometer for ascertaining movable barrier position, regardless of the position of the disconnect system, and provides position information to the operator. A travel limit is set by placing the disconnect system in the disconnected position and manually moving the door to a desired position whereupon the disconnect system is moved to the connected position so that the operator can detect a positional location to be designated as one of the travel limits. An installation switch may be connected to the operator, wherein the operator determines a custom lower limit or a custom upper limit from the desired position as detected by the potentiometer, wherein actuation of the installation switch establishes the custom limit. An up/down switch may also be connected to the operator.  Actuation of the up/down switch during setting of the operational profile and after setting of the custom lower limit sets a custom upper limit.

Abstract: A system and method for a communication terminal to manage memory and maintain a current application version for multiple applications are provided. The system and method provide for managing memory in a communication terminal coupled to a server device enabling the communication terminal to provide memory capacity for storing in a memory and executing on the communication terminal a plurality of applications downloaded from the server device. Prior to downloading an application, the communication terminal determines an amount of memory capacity required by an application client to be downloaded from the server device. The communication terminal then attempts to allocate the memory capacity. If memory cannot be allocated from the system heap, the communication terminal purges data contained in the memory according to a dynamic list of priorities to create memory capacity in the memory for the application client. Once sufficient memory capacity has been created, it is allocated to the application client, and the application client is downloaded to the communication terminal.

Title: Therapeutic device and system
Inventor: KNIGHTON DAVID
IPC: A61F13/08
Filed: 2001-06-28
Abstract: Therapeutic devices (30, 40, 50, 60) that provide support or pressure to tissue. Devices (30, 40, 50, 60) contain a material that is capable of being contracted from its relaxed state to an evacuated state. The material applies pressure to the tissue of a patient when the material is in its relaxed state.  Reduction of pressure by application of a vacuum results in a contracted state of the device, so that the device can be applied or delivered to a patient.  Release of vacuum results in a return to the relaxed state, thus providing a maximum desirable pressure to tissue and avoiding the possibility of over-pressure which can result in tissue damage or necrosis.
