Title: Fuel filter with internal pressure regulator
Inventor: PUCKETT RON
IPC: B01D27/00
Filed: 1999-02-08
Abstract: A fuel filter and pressure regulator assembly includes a housing, an inlet tube, an outlet and return tube each made of stainless steel. An annular filter element is disposed within the housing and abuts at one end a pressure regulator element which is mounted within an O-ring retainer that is fixed within the housing. A resilient device, such as a wave washer or O-ring, is compressed as the assembly is assembled. In operation, fuel flows in through the inlet tube which is radially offset at a first end of the housing and into an annular space around the annular filter element. The fuel then flows through the filter media and the filter element and out of the outlet tube which is aligned with a hollow core of the filter media. If fuel pressure is too high, the fuel then flows through the pressure regulator, out of the return tube and back to the fuel tank.

Title: Method and apparatus for providing error protection for over the air file transfer
Inventor: ZEHAVI EPHRAIM
IPC: H04W28/04
Filed: 1998-05-29
Abstract: In a communication system which conforms to the IS-99 standard, a concatenated code is used to provide for error free file transfer over the air. The concatenated code comprises Reed-Solomon coding (22), CRC  block coding (32), and convolutional coding (36). At the transmitter, the file is partitioned into data frames and Reed-Solomon encoding (22) is performed on the data frames. CRC block encoding is then performed on the Reed-Solomon encoded data. The CRC encoded data is convolutionally encoded (36). The CRC block encoding (32) and convolutional encoding are performed in accordance with the IS-99 standard. The additional Reed-Solomon encoding step provides improved error correction capability while maintaining compatibility with the IS-99 standard. At the receiver, Reed-Solomon decoding (104) is performed if the number of erasures in a code word is less than or equal to (n-k) or the symbol errors in a code word is less than or equal to (n-k)/2. Otherwise, a request for retransmission is sent.
