Patent CA-2495346-A1 (CA)
Title: Maximizing allowable flexible slot-to-cell allocation by using adaptive antennas in a tdd system
Inventor: MARINIER PAUL
IPC: H04L5/22
Filed: 2003-08-11
Abstract: The present invention establishes a system on how to best use adaptive antennas at a base stations and optionally at wireless transmit receive units (WTRUs) to mitigate the interference due to conflicting slot assignments between two neighboring cells. This system will allow for a greater flexibility in slot-to-cell assignments, especially when conflicting slot assignments are for two cells or mobiles in the same vicinity, more specifically, one cell uses a slot assignment for an uplink while the other cell uses the same slot assignment for downlink.

Title: Easy-open moisture resistant packages
Inventor: FORMAN JOSEPHINE A
IPC: B65D65/34
Filed: 2005-05-25
Abstract: Novel package wrappers made of humidity resistant plastic, utilizing a teartape disposed proximate to, but spaced inward from, one edge of the package, extending substantially linearly continuously about three adjacent sides. The teartape in one form of the invention is a separate tape adhered to the package wrapper, and in another form of the invention is integral with and formed from the package wrapper itself. The package is completely sealed but does not require the use of any tool to open it. After the teartape has been removed, fingers or a thumb may be inserted beneath the revealed torn edge of the wrapper and the wrapper torn downward through slits in the then exposed portions of the ends of the package wrapper which had been previously overlaid by the teartape ends, such slits being concealingly disposed and sealed beneath the overlying ends of the intact wrapper before removal of the teartape. By locating the teartape fairly closely to one edge of the package and providing the underlying tear down slits in the package wrapper ends, the intact upper corners of the opened package are able to slide smoothly over and down around the corners of the contained product without exerting any substantial pressure thereon, so that no corner curling force is exerted on the sheets sufficient to cause corner distortion. The wrapper is quickly and easily removable from the contents, so that the dry undistorted paper may be quickly loaded into a copy machine.

Inventor: FUX VADIM
IPC: G06F17/27
Filed: 2005-06-02
Abstract: A handheld electronic device includes a reduced QWERTY keyboard and is enabled with disambiguation software. The device provides output in the form of a default output and a number of variants. The output is based largely upon the frequency, i.e., the likelihood that a user intended a particular output, but various features of the device provide additional variants that are not based solely on frequency and rather are provided by various logic structures resident on the device. The device enables editing during text entry and also provides a learning function that allows the disambiguation function to adapt to provide a customized experience for the user. The disambiguation function can be selectively disabled and an alternate keystroke interpretation system provided. Additionally, the device can facilitate the selection of variants by displaying a graphic of a special <NEXT> key of the keypad that enables a user to progressively select variants generally without changing the position of the user's hands on the device.

Patent CA-2516220-A1 (CA)
Inventor: MITANI TAKUO
IPC: H01M50/437
Filed: 2004-02-03
Abstract: A separator for storage batteries is mainly composed of fine glass fibers.  Each fine glass fiber contains expanded microcapsules. The expanded shape of each microcapsule is maintained, and water permeability is imparted to the case of each expanded microcapsule by the expansion. An electrolyte is held in the interstices between the glass fibers and in the expanded microcapsules.  Therefore, the separator has a high electrolyte holding capability and a strong restoring force for pressing thanks to the action of the expanded microcapsules serving as a cushioning member. As a result, the close contact of the separator with the electrode plate can be maintained over a long period of time, a higher capacity of the battery and a longer service life are achieved. When the battery is assembled, the electrode group can be incorporated in its case only with a weak press force.

Title: Slope, drift and offset compensation in zero-if receivers
Inventor: DENT PAUL W
IPC: H03M13/41
Filed: 1996-03-01
Abstract: A method for processing a signal modulated with information symbols to account for an additive offset and slope is disclosed. First, an initial estimate of offset and slope is made and hypotheses of all possible values of a sequence of one or more information symbols are then made.      For each of said hypotheses, the associated data symbol sequence is used to make an improved estimate of offset and slope and the improved estimate of offset and slope are stored against each of the hypotheses. For each hypothesis, the improved estimate of offset and slope is used in calculating an expected signal value and a mismatch between a sample of the modulated signal and the expected value is computed. The hypotheses are then sequentially extended by one symbol, the slope and offset estimates are updated and the mismatches are accumulated to form a path metric value for each extended hypothesis, and resolving between said hypotheses based on said path metric values using a Viterbi Sequential Maximum Likelihood Sequence Estimation process to produce a most likely hypothesis of said modulated information symbols substantially unimpaired by said additive slope and offset.
