Abstract: An apparatus for attenuation of fluid pressure pulses in a hydraulic system of an automatic transmission is provided. In one embodiment of the invention, a wave tuner is disposed within a fluid conduit between the transmission and a transmission fluid cooler. In another embodiment of the invention, a stand pipe is teed into the conduit with an open end of the stand pipe communicating with the conduit and an opposite closed end reflecting pressure pulses.

Abstract: A method and system using correlator circuitry in a GPS baseband circuit for despreading both GPS data and local wireless data. In one embodiment, an RF signal (local wireless) is received at a first frequency and a digital baseband signal is produced therefrom at a second frequency. A GPS signal is also received at the second frequency and a digital baseband signal is produced therefrom. Both baseband signals are provided to a single GPS baseband circuit for data recovery. In a GPS mode, GPS data is recovered from the baseband signal by despreading and demodulation. In a local wireless mode, the GPS baseband circuit is programmed to despread and recover local wireless data. The GPS data and the local wireless data can be stored in a data buffer for downstream processing. By sharing the correlator circuits in the GPS baseband circuit for both GPS data recovery and local wireless data recovery, a low cost receiver unit is provided.

Abstract: A remote control device is adapted to control a plurality of appliances such as televisions, VCRs, stereos, etc. The remote controller includes a first connector for mating with a plurality of transducer modules, so that the remote control device can be used to emit infrared, radio, or other signals. (In another embodiment, the remote control device includes a plurality of different transducers for providing a plurality of different types of control signals.) The remote control device includes a second connector for mating with a cradle. The cradle can receive signals from external source such as a telephone line. Thus, one can access the remote control device from a remote location and cause the remote control device to control selected appliances. The remote control device also includes a programmable timer so that various appliances can be turned on and off at selected times.
