Title: Liner wiper plug
Inventor: FRASER JAMES M
IPC: E21B33/05
Filed: 1997-07-22
Abstract: An apparatus and method are disclosed for pumping segregated fluids through a tubular member, such as is required when cementing a liner into a wellbore. A liner wiper plug 10 has an internal bore 14 formed therethrough, with a flapper valve 18 mounted in the liner wiper plug 10. A work string 24, or a stinger 30 attached to work string 24, can be positioned within the internal bore 14 of the wiper plug 10, holding the flapper valve 18 in an open position. The wiper plug 10 can be run into the well on a work string, with the flapper valve 18 held open and with flow of a first fluid in progress. The wiper plug 10 can be releasably supported by the liner 22, via shear pins or breakable lugs 20. The work string 24 is withdrawn from the wiper plug 10 to allow the flapper valve 18 to close. Pumping a second fluid through the work string 24 to apply fluid pressure to the wiper plug 10, will release the wiper plug 10 from the liner 22 and force the wiper plug to pass through the liner as desired, segregating the fluids. An alternative embodiment uses a ball type valve instead of the flapper valve.

Title: Audio signal processor
Inventor: EASTTY PETER CHARLES
IPC: H04S1/00
Filed: 1997-10-02
Abstract: In recording for example classical music played by an orchestra (O), a stereo pair (1) is used. To enhance say a quiet instrument such as a flute (F) a spot microphone (2) is used close to the flute. However, the different air-path lengths for the flute to the stereo pair (1) and spot microphone (2) creates undesired effects. The signal from the spot microphone is delayed (4), the delay being automatically controlled by an adaptive filter (5). The filter (5) correlates the spot microphone signal with the signal from the stereo pair to establish the delay time. An alternative arrangement uses an adaptive filter trained by the signal from the spot microphone to extract the flute signal from the stereo pair. In other arrangements, similar techniques are used to cancel undesired noise.

Title: Serial Searcher for a DSSS Receiver
Inventor: MOON HI-CHAN
IPC: H04B1/7085
Filed: 1997-12-03
Abstract: A multiple dwell time searcher for use in a receiver of a direct sequence spread spectrum (DSSS) system is described. A pseudo noise (PN) code generator generates a series of PN codes. A mixer mixes a received signal with the PN code generated by the PN code generator to output a de-spread signal. An accumulator accumulates the de-spread signal from the mixer to produce an accumulated result. A first energy value of the received signal is calculated based on the result accumulated by the accumulator during a first dwell time using a first PN code, the calculation taking place during a subsequent first dwell time during which the accumulator accumulates the de-spread signal from the mixer using a subsequent PN code in the series. A second energy value of the received signal is calculated based on the result accumulated by the accumulator during a second dwell time using the first PN code if the first energy value is higher than a first threshold value.

Title: Detecting capacity of cache memories
Inventor: CHANG YU-CHUAN
IPC: G06F12/08
Filed: 1998-12-24
Abstract: A method of detecting the capacity of caches, including the L1 cache built into the CPU and any second level cache (L2) outside the CPU. The method uses a database with varying sizes of data files, and monitors the reading time of the CPU for each size of data file when reading the data from the L1 cache, the L2 cache or the main memory respectively. Because the reading speeds relating to the L1 cache, L2 cache and main memory are different, the capacity of the L1 and L2 cache can be determined by matching the change in reading speed to corresponding sizes of data files.
