Title: Stabilization ring and seal clearance for a scroll compressor
Inventor: DUMOULIN TERRENCE R
IPC: F04C27/00
Filed: 1998-03-19
Abstract: An axial compliance mechanism for a scroll-type compressor including a fixed scroll member, an orbiting scroll member and a bearing pad spatially fixed in relationship to the fixed scroll member. The axial compliance mechanism biases the orbiting scroll towards the fixed scroll by applying a fluid at high pressure to a radially inner portion of the back surface of the orbiting scroll member and a relatively lower pressure to a radially outer portion of the back surface. An annular stabilization ring is placed between a main bearing pad and the rear surface of the orbiting scroll lifting the orbiting scroll into engagement with the fixed scroll and inhibiting the tilting and wobbling of the orbiting scroll. The annular stabilization ring also maintains a clearance between the rear surface of the orbiting scroll and the main bearing pad thereby improving the performance of a sealing member disposed between the main bearing pad and the rear surface of the orbiting scroll member during start up of the compressor. The annular stabilization ring lifting the scroll member into engagement with the fixed scroll may be located in a shoulder at theouter periphery of the orbiting scroll member or it may form the annular portion of an Oldham ring which controls the orbiting motion of the orbiting scroll member.

Title: Method and apparatus for automatic compensation of first-order polarization mode dispersion (pwd)
Inventor: FISHMAN DANIEL A
IPC: H04B10/18
Filed: 1998-08-19
Abstract: The effect of polarization mode dispersion that an optical signal experiences as it propagates through an optical transmission fiber is compensated for at a receiver using a birefringent compensator, in which the compensator automatically and adaptively generates a level of differential time delay that substantially equals the differential time delay that the optical signal experiences, but of different sign, and, therefore, essentially cancels out the undesired delay.

Title: Track-supported playground shuttle
Inventor: HENRY BRIAN
IPC: A63G21/20
Filed: 1998-10-05
Abstract: A playground shuttle device includes a track having an upper surface and a lower surface and a support structure connected to and supporting the track.  The shuttle device includes a shuttle having a housing defining a chamber through which the track traverses and a transport assembly carried by the housing. The transport assembly includes a plurality of wheels rotatably mounted thereto and positioned so as to ride along the upper surface of the track. The transport assembly includes a brake assembly operably connected thereto by a biasing element. The brake assembly includes at least one brake element that is engagable with the track. The brake assembly is movable relative to the transport assembly between a brake position wherein the brake element engages the track and a free-roll position wherein the brake element is disengaged from the track. When a force is applied to the brake assembly against the biasing element, the brake elements are disengaged from the track to move the shuttle to the free-roll position. Removal of the force from the brake assembly engages the brake element with the track to move the shuttle to the brake position.

Title: Method and apparatus for high-speed block transfer of compressed and word-aligned bitmaps
Inventor: MUNSHI AAFTAB A
IPC: G09G5/393
Filed: 1997-02-27
Abstract: Graphics display is performed by compressing pixel information, by aligning the 8, 16, or 32 bit pixels transferred over a 32-bit Peripheral Component Interface (PCI) bus (609) with the pixels in the display memory (612), and by avoiding moves of pixel data within display memory (612). Compression is achieved by not transferring data for pixels that are not modified by the transfer. Rather, a count of unmodified pixel bytes to skip precedes each set of pixel data for contiguous pixels that are modified. Alignment is achieved by ensuring that the boundaries between words within the pixel set transferred matches those within the corresponding target pixels in the display memory (612). This alignment significantly speeds up modifying pixel data within the display memory (612). The burden of ensuring this alignment is placed on the applications software that initiates the transfer.

Title: Method and apparatus for analyzing international long distance dialing errors and automatically completing a call
Inventor: NEMETH RONALD
IPC: H04M3/493
Filed: 1998-10-26
Abstract: A method for analyzing international long distance dialing errors and automatically completing a call if the error can be determined comprises the steps of receiving a dialed country code, city code and directory number. A potential error is determined by comparing one or pairs of the dialed country code and city code or the city code and dialed directory number or the combination of all three elements with predetermined valid dialing sequences for the dialed digits. For example, an error can be located between the country code and city code when a foreign telephone network has added a digit, for example, to expand the number of directory numbers available within a geographic area. A list of obsolete country codes, city codes or combinations thereof is stored in memory along with updated country codes and city codes. In one embodiment, a corrected dialed number is automatically redialed without further action by the caller. In another embodiment, the existence of a potential error in a dialed number is announced to the caller. The caller can further be prompted to agree with a reasonable correction of the dialed number and permit the automatic readiling of the telephone number intended. Apparatus for performing the analysis may comprise a known long distance network adjunct processor including a voice interactive system and access to a database of obsolete and valid international calling formats. In an alternative embodiment, even the dialed directory number may be corrected via access to a remote directory number database or international operator assistance may be provided.
