Title: High-speed facility protection in a digital telecommunications system
Inventor: RICHARDSON C DOUGLAS
IPC: H04L69/40
Filed: 1993-05-17
Granted: 1998-07-21
Abstract: A digital communications system with fast facility protection is disclosed.  The system includes at least one digital   cross-connect   which   is   in   bidirectional communication with east and west routes of the network via east and west transmit ports and east and west receive ports.  The cross-connect broadcasts a facility over both the east and west routes, and receives the return facility over one of the routes.   The cross-connect monitors the error  status  of  the  received  facility  for  hard  error conditions  and  excessive  error  rates,  by  way  of  a distributed processor in communication with the port.  In the event of an error, the cross-connect blind switches the facility to the inactive port by way of a receive-end switch,  according to a first embodiment.   According to another embodiment, a head-end switch is performed, thus allowing for improved flexibility for port assignment in the cross-connect.

Granted: 1999-02-23
Abstract: A radio frequency automatic identification system detects targets which include solid resonators (12) resonating at several frequencies, attributing information to the frequencies at which the target resonates. Preferred resonators are quartz crystals, which may be made by a process of heating quartz to soften it and cutting crystals to approximate size and resonant frequency. Resonators produces by such a process are measured to determine their actual resonant frequency, and preferably the crystals are sorted into predetermined frequency windows in accordance with their measured resonant frequency. A set of resonators (12a-12n) having frequencies corresponding to predetermined data is selected from the sorted groups of resonators and incorporated into a target. The preferred target is an ink-like material having a plurality of resonators disposed in a matrix which is radio frequency transparent at the frequency of interest. Targets are preferably detected by repetitively sweeping the frequency of the interrogating signal through a range which includes the information-bearing range of the system.

Title: Engine nox reduction system
Inventor: BERRIMAN LESTER P
IPC: F02B1/04
Filed: 1992-04-20
Granted: 2002-12-24
Abstract: A method and apparatus are provided for reducing pollutants and especially nitrogen oxides, or NOx, in the exhaust gases of an engine. The apparatus includes a device for injecting-ammonia into a conduit that extends between cylinder exhaust valves and a catalytic converter, to mix the ammonia with the exhaust gases. Ammonia injection occurs at a location a plurality of inches downstream of the exhaust valves to avoid burning of the ammonia by flames.  The injection preferably occurs at a location where the exhaust gases are at a temperature of at least about 1200 °F to cause considerable reaction of the ammonia with NOx in the exhaust gases prior to the gases reaching the catalyst, so less NOx must be removed along the catalyst. To minimize ammonia use, it is injected only for a limited period such as a minute after a cold engine is started when the catalyst is too cold to cause signifi-cant reactions, and during operation of the engine at high power levels when the greatest amounts of NOx are produced.

Title: Connections between a toll network and multiple local networks
Inventor: AKINPELU AKINWALE ADEMOLA
IPC: H04Q3/00
Filed: 1994-12-08
Granted: 1999-11-02
Abstract: An arrangement for routing toll calls to a predominant local exchange carrier (LEC) or to a competitive access provider (CAP). An egress switch of an interexchange (toll) carrier translates the called directory number office code to determine whether that code serves a CAP. If so, an exception table is searched to identify the CAP; if the called number is not in the exception table, the call is routed to the predominant LEC. Calls may also be routed to a customer who is served by a, CAP and the predominant LEC via either of these local carriers. The billing record identifies an originating and/or a terminating CAP for the call. Optionally or alternatively, the ingress IXC switch may access a data base to determine the CAP or predominant LEC serving a called customer; the ingress IXC switch then routes the call to an IXC egress switch serving the carrier that serves the called customer. Advantageously, this arrangement efficiently serves calls using a CAP to provide part of the connection.
