Patent CA-2281027-A1 (CA)
Inventor: LACONTE PETER KEITH
IPC: H04B1/707
Filed: 1999-08-30
Abstract: A wideband code division multiple mess (CDMA) communication system overlayed on an IS-95 network generates two car more digital bit streams from a group of wideband digital data streams, each digital bit stream spread to foam a CDMA component signal. Each CDMA component signal is combined with a corresponding IS-95 digital bit stream to form a composite CDMA signal, allowing a base station to share transmitter subsystems between the wideband and IS-95 systems. For up to three carrier frequencies, up to three composite CDMA  signals are employed. A digital bit stream for a group of summed user conversations in the IS-95 system modulates a respective RF carrier frequency to generate a low-power RF signal.  The CDMA component signals of the wideband CDMA system are generated so each has a chip rate identical to the chip rate of the digital bit streams of the IS-95 system. The baseband digital data streams for all wideband user conversations are summed digitally for each targeted RF  carrier frequency to produce the composite wideband digital signal for each targeted frequency.  In one application, each composite wideband digital signal, each at the IS-95 chip rate, is then used to modulate a carrier frequency which is either the same, or has approximately the same frequency and phase as the carrier frequency used in the IS-95 system. Three low-power RF signals are produced in the wideband system, each having the same spectral characteristics as the corresponding low-power RF signals generated in the IS-95 system. These low-power RF signals at the same frequency are combined into a single signal provided to the amplifier and antenna subsystem of a base station transmitter. In another application, each composite digital signal is digitally combined with a respective IS-95 digital bit stream. prior to modulation by respective RF  carrier. Therefore, signal combining between the IS-95 and wideband CDMA portions of a base station system is accomplished either digitally or with RF signals prior to amplification, thereby allowing the IS-95 system and wideband CDMA system portions of the base station to share RF  filters, amplifiers and antennas of the base station transmitters.

Title: System and method for efficient manufacturing of liquid crystal displays
Inventor: DRABIK TIMOTHY J
IPC: G02F1/1345
Filed: 1998-04-03
Abstract: The present invention enables efficient microfabrication of a fully integrated liquid crystal display device (20). Initially, a sacrificial layer is patterned, and portions of the sacrificial layer are removed to expose portions of the underlying layer supporting the sacrificial layer (37). Then, a permeable layer is formed on the sacrificial layer (35), thereby filling in the space vacated by the removed portions of the sacrificial layer (37). The structure is heated and the material of the sacrificial layer is allowed to dissolve into and dissipate through the permeable layer in order to leave a cavity (37). Once the sacrificial layer is removed, the permeable layer (35) is supported by the portion of the permeable layer filling in the space vacated by the removed portions of the sacrificial layer. Accordingly, a monolithic liquid crystal display (20) is easily and reliably formed without having to etch an opening in the structure to allow the sacrificial material to egress from the structure and without having to separately attach mechanical components to each liquid crystal display manufactured.

Abstract: The high pressure system (10) is provided for outputting pressurized fluid to a source, such as a blasting gun (26). The system includes mechanical transmission (14) interconnecting a diesel engine (12) with a positive displacement pump (20). A programmable controller (30) is provided for receiving signals from a pressure transducer (34) and for controlling operation of an engine controller (44), a clutch controller (42), and a transmission shifter (46) to obtain the desired fluid pressure level output from the pump. The controller preferably communicates by wireless transmission technology, so that the controller (30) may be exterior of a sound abatement enclosure (28) surrounding the engine (12) and the transmission (14).  Controller (30) may be operated to automatically shift the transmission in response to fluid pressure output from the pump. Alternatively, controller (30) may receive input instructions from the operator to shift the transmission to a desired gear. In either case, the controller (30) automatically regulates engine speed (rpm) and engages and disengages the clutch for automatically shifting the transmission.

Filed: 2000-07-05
Abstract: At the time of vehicle start-up from the state of engine stopping, a hydraulic oil pressure (PSC) in a starting clutch (7) sometimes overshoots beyond a creeping pressure as a result of a rise in the hydraulic oil pressure in the hydraulic circuit, resulting in shocks. A hydraulic oil pressure command value (PSCCMD) to a linear solenoid valve (15 3) which controls the starting clutch pressure (PSC) is made smaller than the creeping pressure until the point of time at which the rise in the hydraulic oil pressure in the hydraulic circuit (= the point of time at which a condition of F2 = 1 is satisfied). Once a discrimination of a rise in the hydraulic oil pressure has been made, the command value is made higher than the creeping pressure for a predetermined period of time (i.e., for the period of YTM3 - YTM3B1), and is thereafter made to the creeping pressure.

Title: System and method for reverse link overload control
Inventor: KIM KYOUNG II
IPC: H04B7/155
Filed: 2000-09-22
Abstract: A system and method for controlling call admission in a wireless communications network recursively estimates reverse link load levels as a function of changes in base station receive power and/or the number of mobiles served in the cell/sector. In one implementation, a call admission controller utilizes multiple load level estimating methods, whereby a first method estimates load as a function of changes in base station receive power and changes in the number of served mobiles. The call admission controller uses a second method to recursively update load level estimates as proportionally changing with number of users. The call admission controller may utilize a third estimate method as an accuracy check based on a changes in base station receive power measurements.      The call admission controller outputs a call blocking command when load level estimates exceed a threshold to avoid cell/sector overload conditions and network instability.
