Title: Medical device with morphology discrimination
Inventor: WILLIAMS MICHAEL O
IPC: A61B5/363
Filed: 1992-02-19
Granted: 1995-12-05
Abstract: A medical device is provided for monitoring waveform complexes of intracardiac electrograms.          The   intracardiac   electrogram   is  identified   by determining,  with respect to a waveform peak of the intracardiac  electrogram,  its  amplitude,  width  and polarity.  The identification criteria are averaged and stored  to  provide  a  standard  complex.    Subsequent complexes are compared to the stored standard complex.          Such comparison includes comparing peaks of subsequent complexes with the peaks of a stored standard complex, aligning subsequent complexes with a stored standard complex,  and providing  a  score associated with the comparisons and alignment.

Inventor: NATARAJAN KADATHUR S
IPC: H04L12/28
Filed: 1992-08-27
Granted: 1998-05-05
Abstract: A wireless communications network includes a local area network connected to a plurality of nodes which perform bidirectional wireless communication with mobile stations as controlled by a controller. Each node has a geographic area, termed a cell, within which mobile stations can communicate with the node associated with the cell. A cell interference graph is read into the controller, and a maximal independent set of nodes is determined. Each node in the maximal independent set of nodes are put in a set termed ACTIVE for performing wireless communication with mobile stations in their respective cells. Nodes which are not in the maximal independent set of nodes is put in a set termed WAITING to wait for permission to enter the set ACTIVE. A node in the set ACTIVE which has completed communications sends a completion signal to the controller. The controller then examines which of the nodes in the set WAITING is not adjacent to another node in the set ACTIVE, and such nodes are entered in a set termed CANDIDATES. Nodes in the set CANDIDATES are moved to the set ACTIVE according to predetermined criteria.

Abstract: A connector member for connection to a T-bar is in the form of a plate with a lug extending from one side. The T-bar has an aperture which snugly receives the lug when the plate is applied on the side of a web of the T-bar.  The lug extends through the aperture and defines an opening with the side of the web opposite the side on which the plate is applied.  The opening faces longitudinally of the T-bar.  A keeper member is slidable longitudinally from a locking position in the opening in which it resists lateral withdrawal of the lug from the aperture to an unlocking position in which the keeper member disengages the lug and allows the plate to be separated from the T-bar web.

Title: Polarization pattern diversity antenna
Inventor: JOHNSTON RONALD H
IPC: H01Q13/10
Filed: 1993-04-30
Granted: 1998-06-23
Abstract: A polarization pattern diversity antenna is described that is easy to manufacture, has a compact planar shape and radiates a nearly omnidirectional radiation pattern in the horizontal plane. Two feed points, each one attached toa copper patch, are operated in phase and 180° out of phase to separately receive or transmit two different components of a signal. The copper patches are arranged symmetrically on one side of a dielectric layer in such a way as to reduce the r.f coupling between the two modes of operation and thus increase the radiation efficiency and isolate the overall input/output ports for the different signal components.  The ground plane, situated on the underside of thedielectric layer, allows the antenna to operate like a resonant slot when the feed points are excited in phase. Using diversity, the antenna can reduce the multipath fading effects inherent in mobile communications

The simulcast schedulers (45) provide the selective call message to corresponding transmitters (15') at a time to transmit the selective call message, the time determined by the transmission time and the equalization time. Transmitter settings and code types defining signalling protocol, data bit rate, carrier frequency and transmitter power, for each message are varied in accordance with information received from the system controller (12'). Each simulcast scheduler (45) can also function as a selective call terminal for a local selective call system.
