Patent CA-2180701-A1 (CA)
Inventor: REDDEN GALEN
IPC: H01M2/16
Filed: 1996-07-08
Abstract: Battery plate envelopes include a sheet of porous film material having a folded widthwise bottom edge and overlapped lateral edges to thereby form a pocket for receiving a battery plate therein.  The overlapped lateral edges are joined to one  another by a lengthwise extending  series of discontinuous joining regions with adjacent ones of the discontinuous joining regions being separated by respective unsealed  regions.  These unsealed regions thereby establish respective lateral channels through which fluid (e.g., electrolyte employed in a wet storage battery) may pass to the interior pocket, and hence to the battery plate.  The discontinuous joining regions are most preferably formed by passing the sheet material through the nip between opposed joining rings, each of which is provided with a series of triangularly-shaped teeth with smooth land areas formed between adjacent teeth series.

Abstract: A synchronizing apparatus for a differential OFDN receiver that simultaneously adjust the radio frequency and sample clock frequency using a voltage controlled crystal oscillator to generate a common reference frequency. Timing errors  are found by constellation rotation.  Subcarrier signals are weighted by using complex multiplication to find the phase differentials and then the timing errors. The reference oscillator is  adjusted using the timing errors. Slow frequency drift may be compensated using an integral of the timing error. Frequency offset is found using the time required for the timing offset to drift from one value to another.

Abstract: A cutting jig for collapsible cylindrical product, such as foam insulation tube.  The jig comprises a channel which may have parallel side surfaces for supporting the tube and also inclined tube support surfaces extending downwardly and inwardly  from the  side  surfaces.   The  inclined  support surfaces increase the positions of support contact with the tube around its lower regions to hold the tube firmly towards its cylindrical condition during cutting.   Support of the lower regions of tube tends to stiffen the tube upper regions to hold the whole tube toward or into a cylindrical condition with insignificant collapse during cutting.  The channel may provide a support channel for an insert channel for nesting insertion inside the support channel.  The insert  channel also has side and inclined support surfaces for supporting a tube of smaller diameter during cutting.   A further and smaller  insert  channel  is  also  provided  similar  in construction to the insert channel.   The smaller  insert channel is nestable within the insert channel for supporting a yet smaller diameter tube during cutting.  Alternatively, each channel may have a concave tube support surface which is preferably semicylindrical.

Title: Digital communications on overlapping channels
Inventor: SHALVI OFIR
IPC: H04J1/12
Filed: 1996-05-15
Abstract: A single transducer digital communication receiver is described which is capable of extracting the data bits of at least one desired signal in the presence of interfering signals of similar type. The present invention also seeks to provide a communication system in which overlapping transmissions are tolerated and allowed. The present invention describes a design for a digital communication system, according to a specific frequency plan, which includes an appropriate digital demodulator that extracts the data bits of the desired signal(s) in the presence of closely spaced signals. The present invention enables reduced channel spacing in digital communication systems and thereby increases the system capacity (i.e. the number of users per bandwidth unit) without incurring any significant loss in system performance (e.g. power margins, BER, and channel availability). It also allows a reduced power margin that is required to maintain a pre-specified performance level without sacrificing system capacity. These two factors, power margin and system capacity, play a central role in the design and construction of state-of-the-art digital communication systems which seek to pack more users on the same frequency band without incurring significant power loss. Thus, the present invention also provides a method and apparatus for upgrading existing systems such as a cellular system for mobile wireless communications that is based on the IS-54 or the GSM standard.
