Title: Direct access paging for wireless sets
Inventor: CHAVEZ DAVID LEE JR
IPC: H04W68/00
Filed: 1996-11-06
Granted: 2000-09-05
Abstract: A PCS switching system where a wireless set registers on a base station regardless of whether the base station has capacity to complete a call for the wireless set. When an incoming call is received for the wireless set, a central computer providing overall control of the PCS system directs this call to a paging zone controller of a paging zone in which the wireless set is registered. If the base station does not have capacity to handle that call, the paging zone controller transmits a message via the base station and a paging channel to the wireless set informing the wireless set that a page is pending and that it must find a base station with idle capacity. The wireless set does this by listening to the paging channel until a base station is determined that has idle capacity. The base stations periodically transmit on the paging channel, and each of their messages includes the present capacity of the base station. The wireless set establishes communication with the new base station and ceases to be in communication with the original base station. Since the wireless set is already registered with the paging zone controller, it is not necessary for the paging zone controller to re-register the wireless set with the wirelessswitching network when the wireless set moves from one base station to another base station within the same paging zone.

Abstract: Line voltage and line current signals are sensed on a power line having at least one conducting path. The sensed line voltages and line currents are converted into a digital signal. A phase-to-neutral voltage signal and phase current signal are computed from the digital signal to thereby define a phase of the power line. An interval of orthogonality is determined from the sensed voltage and current signals, coinciding with passage of an integral number of cycles of a fundamental frequency reference signal which is computed from the computed phase-to-neutral voltage signal. A vector metering quantity is computed for the determined interval of orthogonality from the computed phase-to- neutral voltage signal and the computed phase current signal. The vector metering quantities to be computed may be identified and computed based upon an associated detent. The vector metering quantity is also computed based on an identified circuit topology.

Title: Optical communications system employing spectrally sliced optical source
Inventor: KOREN UZIEL
IPC: H04B10/272
Filed: 1997-07-02
Granted: 2001-09-11
Abstract: An apparatus and method provides optical multiple wavelength signals using a single, broadband optical source such, for example, as an LED, to generate many independent optical wavelength channels. An optical transmitter includes a wavelength channel defining assembly which resolves the broad spectrum pulses output by the source into discrete wavelength bands constituting respective pulses (i.e., wavelength channels) and which inserts a delay between the bands to define a sequence of individually addressable channels. In accordance with one embodiment of the invention, spectral splicing is achieved by a multiple channel filter, and insertion of the respective delays is achieved by individual fiber sections, each section having a length selected to introduce a particular delay, coupled to the output ports of the router. The inserted delays can be conveniently selected to separate adjacent wavelength channels and thereby minimize the likelihood of crosstalk. Pulses of the thus-resolved channels arrive at different times to a multiplexer which may be configured, for example, as a passive WDM multiplexer or as a star combiner. The resulting sequence of addressable wavelength channels may be supplied to one or more high-speed, broadband modulators, with each modulator being operable to modulate some or all of the channels.

Title: Frequency-hopping spread-spectrum radio communications
Inventor: JANDRELL LOUIS H M
IPC: H04L12/56
Filed: 1998-08-07
Granted: 2004-02-17
Abstract: A method and apparatus for accessing a communication channel in a communications system having a transmitter and a receiver. Frequency-hopping spread-spectrum techniques are utilized in which the transmitter of the message assigns a message a priority. Once the message is assigned the priority, the transmitter then selects one of the frequencies from a set of pre-determined randomly-ordered set of frequencies utilized by the spread-spectrum system. Once the frequency is selected, a timer is set to a hop interval and started. The transmitter then senses the channel. If the channel is not clear by the time the timer expires, the transmitter returns to the step of selecting a frequency and resetting the timer. Once an available frequency is discovered, the method waits an interval based on the priority of the message. If the channel is still available the message is then transmitted. If the channel is not available, the timer is then checked, if the timer has expired, then the transmitter returns to the step of selecting a frequency and resetting the timer. Otherwise the transmitter continues to sense the channel. The transmitter waits for an acknowledgment after transmitting the message. If an acknowledgment is not received before the timer expires, then the sequence re-starts. Another aspect of the invention is a fast scanning algorithm in which a next frequency is selected from a pre-determined set of frequencies.  The Received Signal Strength Indication (RSSI) at that frequency is then measured. When the measured RSSI is above a threshold, a first timer is started. A second timer is then started when bit synch has been achieved. A data packet is then read and validated. The sequence is repeated continuously. When a frequency is scanned and the RSSI is below a threshold, the method returns to selecting the next frequency. If the first timer expires and bit synch has not been detected, the method stops and returns to select the next frequency. The sequence also aborts and another frequency is selected if the data cannot be validated or there is no more data at the selected frequency. The invention provides apparatus and computer-readable instruction code for carrying out the fast-scanning method, and a system with aspects of both the transmitter and receiver of this invention.
