Abstract: An automated method for modifying a speech signal in a telephone network by applying a gain factor which is a function of the level of backgroundnoise at a given destination, and transmitting the modified speech signal to thedestination. The gain applied may be a function of both the background noise level and the original speech signal. Either a linear or a non-linear (e.g., compressed) amplification of the original speech signal may be performed, where a compressedamplification results in the higher level portions of the speech signal being amplified by a smaller gain factor than lower level portions. The speech signal may be separated into a plurality of subbands, each resultant subband signal being individually modified in accordance with the present invention. In this case, each subband speech signal is amplified by a gain factor based on a corresponding subband noise signal, generated by separating the background noise signal into acorresponding plurality of subbands. The individual modified subband signals maythen be combined to form the resultant modified speech signal.

Title: Elevator brake with shoes actuated by springs
Inventor: GLASER WALTER
IPC: B66D5/26
Filed: 1993-06-22
Granted: 1999-09-07
Abstract: An emergency brake for an elevator car. The problem with car brakes is the uneven braking force applied and un-even wear of the linings. The elevator employs springs which maintain a constant braking force on the shoes. The springs (15, 16) are compressed by a fluid operable piston and cylinder assembly (35). The springs (15, 16) move a cam follower (17) along cam surfaces (20, 21) shaped to cause the cam follower (17) to move one brake shoe (22) toward the other shoe (24). Switches (63, 57) operable by the cam follower (17) control the car (4) so that movement of the car (4) is prevented when the springs (15, 16) are not compressed and when there is excessive shoe wear.

Abstract: delay spread detection and compensation arrangement effectively detects distortion due to multipath delay spread in a digital channel and compensates for this distortion with minimum circuit complexity. An improvement in the bit error rate performance for a differential detector in the receiver is achieved through use of a a detected direct current (DC) component, which is proportional to the amount of multipath delay spread on the digital channel. This DC component is used in the differential detector for compensating for this delay spread. In addition, the differential detector also provides a channel quality measure of the level of delay spread on the digital channel for use by the receiver in selecting either the differential detector or an equalizer for decoding of the data on the digital channel. When the level of delay spread is low, a processor used by the equalizer is freed for other computational tasks or, when the bit error rate permits, is not used at all thereby realizing a reduction in power consumption in the receiver.

Title: Computer operating system providing means for formatting information in accordance with specified cultural preferences
Inventor: MILLER GARY W
IPC: G06F9/40
Filed: 1995-03-30
Granted: 2001-05-08
Abstract: A system is disclosed for presenting information which reflects the users' cultural preference, including language and other conventions, that can manage locale categories without requiring application programs to manage all the overhead of repetitive changes to locale category values. Users merely specify their cultural preferences through the application programs and the operating system assigns a stack from the working memory for each specified category of cultural preference, and pushes onto the stack the location in the working memory of a file for the category of cultural preference specified, the file having been transferred from a locale database of files that contain code formatting according to the cultural preferences. In a second aspect of the operating system, multiple concurrent sets of cultural preferences are handled by determining whether a location in the working memory corresponding to the preference specified is currently in the queue, and if not, by placing a new value in the queue for each memory location corresponding to an additional set of locale category values.

Title: Group call in a cellular radio system
Inventor: YARWOOD ANTHONY CHARLES
IPC: H04W4/90
Filed: 1994-05-23
Granted: 2002-02-26
Abstract: In a cellular radio system the facility is provided for a call to be broadcast from a control centre (Mx), (for example an emergency service controller), or from any of the mobile units (Ma), (Mb), (Mc) etc., to all of the others. Each cell allocates a single channel to the broadcast service, irrespective of the number of mobile units in the cell.  This allows more efficient use of the available channels than the use of a separate channel for each mobile unit. In one embodiment no channel is allocated to a cell unless at least one mobile unit responds to a paging signal in that cell. Paging may continue throughout a broadcast call to allow a channel to be allocated when a mobile unit enters a previously unoccupied cell or to allow please of a channel should all mobiles leave a previously occupied cell. The broadcast facility can be provided on a cellular network which also supports other mobile units which do not receive the broadcast service, and whose operation is not affected by it.

Abstract: The inventive device is a connector for mounting a vertical exhaust pipe to a truck cab. In one embodiment, the connector includes a bracket, a resilient member, a rigid bushing, a rod, and a clamp. The bracket is mountable to the cab in the proximity of the exhaust pipe. The resilient member is coupled to the bracket, and the bushing is coupled to the resilient member. The rod has an upper end and a lower end, and it is positioned through the bushing. The clamp has a brace attached to an end of the rod and a clasp that is attachable to the exhaust pipe. The rod is moveable axially through the bushing to correspond to vertical displacement between the cab and the exhaust pipe, but the rod is substantially prevented from moving laterally with respect to the cab to substantially prevent lateral displacement between the exhaust pipe and the cab. The resilient member is made from a material that dampens vibrations from the exhaust pipe to reduce noise in the cab.

Abstract: An improved method of speech coding for use in conjunction with speech coding methods wherein speech is digitized into a plurality of temporally defined frames, each frame including a plurality of sub-frames, and the digitized speech is partitioned into periodic components and a residual signal. For each of a plurality of sub-frames of the residual signal, the improved method of speech coding selects and applies a time shift T to the sub-frame by applying a matching criterion to (a) the current sub-frame of the residual signal, and (b) a sample-to-sample (sub-frame-to-subframe) pitch delay determined by applying linear interpolation to known pitch delays occurring at or near frame-to-frame boundaries of previous frames. The matching criterion is applied by minimizing .epsilon., where:               .epsilon. = .SIGMA.(r(n-T)-r(n-D(n)))2.     n (r(n-T)) is the residual signal of the current frame shifted by time T, r(n-D(n)) is the delayed residual signal from a previously-occurring frame, n is a positive integer, r is the instantaneous amplitude of the residual signal, and D(n) is the sample-to-sample pitch delay determined by applying linear interpolation to known pitch delay values occurring at or near frame-to-frame boundaries.
