Title: Apparatus and method for eliminating mapping jitter
Inventor: BELLAMY JOHN C
IPC: H04L7/00
Filed: 1994-11-28
Abstract: A desynchronizer (10) for eliminating output mapping jitter includes a demapper circuit (12) for reading asynchronous data and clock rate of an embedded signal within a synchronous channel (14). The payload data is buffered in an elastic store circuit (ESC) (17). The demapper circuit (12) outputs bit stuff and pointer justification timing adjustments (PJTAs) to an overhead gapfill circuit (OHGC) (19) and a pointer justification leaky accumulator circuit (PJLAC) (20). The OHGC (19) calculates overhead gaps within the payload data to generate a gapfill value (34). The PJLAC (20) determines the bit stuffs and pointer justifications in the payload data to produce an accumulated value (36). The gapfill and accumulated values (34, 36) are combined with an elastic fill value (EFV) (18) from the ESC (17) to eliminate instantaneous variations and reduce the effects of bit stuffing and PJTAs in the EFV (18). An adjusted fill value goes to a clock recovery PLL circuit (CRPLL) (29). The CRPLL (29) generates a clock for transmitting the data from the ESC (17).

IPC: H04L25/03
Filed: 1995-05-26
Abstract: A digital communications receiver provides joint MLSE equalization and diversity combining.  A plurality of diversity branches are processed to produce complex receive data samples and synchronization information.  Channel estimators then form channel estimates from the data samples and synchronization information.  The data samples and channel estimates are then used by pre-processors to produce metric multipliers.  Finally, the metric multipliers are combined with hypothesized data sequences to generate and accumulate metrics using a sequence estimation algorithm to produce a demodulated data stream.

IPC: H01M4/62
Filed: 1995-08-18
Abstract: A lithium ion battery comprising a negative electrode, a non-aqueous solvent and a positive electrode having LiV2O5 admixed with a conductive material.

IPC: B65B47/08
Filed: 1997-03-26
Abstract: A method for making sterile suture packages employs a frame assembly line, a sterilization line and a blanker/cartoner line. A web of foil is advanced in a series of movements through the frame assembly line to assemble a frame containing needle-suture assemblies in a plurality of cavities in the frame, the frame having top and bottom aluminum foils with heat seal coatings on their facing surfaces. The cavities are formed in the bottom foil of each frame by a combination of pressurized air and mechanical plugs which are forced against the bottom foil and an underlying die having recesses for defining the cavities. A blanking operation following sterilization and sealing separates individual packages, each containing one needle-suture assembly, from the frame. The packages are then conveyed by belts through inspection stations and reoriented for loading into shipping cartons.

Inventor: YEUNG SHU-KI
IPC: E03D5/012
Filed: 1997-08-11
Abstract: To eliminate  the  necessity  of  a water  tank,  this invention converts the traditional toilet bowl with siphonic water trap into a toilet basin with a tilting-bowl. This  invention comprises  a frame,  a  toilet basin, a tilting bowl and a trigger means.  The tilting bowl serves as a movable water/waste container.  In its not  tilted  horizontal  position,  the  tilting  bowl receives and holds water/waste delivered to it through the toilet basin.   When the tilting bowl tilts,  it dischrages  its  content  to  drainage  pipe  through  a bottom   discharge   hole;   simultaneously   allowing water/waste to discharge from basin to drainage.   The tilting bowl  is  normally  retarded  to  stay  in  its horizontal position by forces applied to the tilting bowl  creating  a  resultant  retarding  turning moment about its pivot point larger than the turning moment produced by the tilting bowl with its content.   When triggered, the trigger means helps to remove or reduce the retarding turning moment, allowing the tilting bowl to  tilt  and  discharge  water/waste  to  outside  the toilet.

Patent CA-2214838-A1 (CA)
Inventor: ADAMS JOHN LEONARD
IPC: H04L12/54
Filed: 1996-03-08
Abstract: In a broadband switching system for the switching of asynchronously transferred cells of data, a dynamic bandwidth controller (DBC) controls the application of data cells to an input port of the system, the data cells being supplied by a number of transmitting end-systems. When an end-system begins transmitting data cells, the DBC  detects the presence of incoming cells and requests bandwidth from a connection admission control (CAC) forming part of the system. The switching system stores a table associating a number of signal sources connected to the ingress with respective predetermined transmission bandwidths and, preferably also, maximum delay times. When arrival of cells from one of the sources at the input port is detected, the DBC sends a request signal for the relevant predetermined bandwith to the CAC and delays transmission of the cells until at least the predetermined bandwidth is allocated. This delay is typically effected by sending a cell rate indicator signal back to the input port for placing the source in a halt mode. If no allocation of bandwidth has occurred before the respective maximum delay time, bandwidth is allocated by robbing bandwidth from other signal sources.
