Title: Multi-hop telecommunications systems
Inventor: JAVITT JOEL I
IPC: H04W84/10
Filed: 1998-02-12
Granted: 2002-04-02
Abstract: Free-space, line of-sight, electro-magnetic communication (i.e., via light or microwaves) is employed to provide a wide range of communication services to geographically scattered users. A relay point or end point is typically associated with each user. Each relay point receives and retransmits information via line-of-sight communication. The end points are also receivers and transmitters of information via line-of-sight communication. Although spaced from one another, the relay and end points are close enough to one another to communicate via line-of-sight links. Hard-wired connections to the users are therefore unnecessary. Broadcast radio frequency communication capability may be provided as a backup for maintaining at least some service in the event of line-of-sight communication failure or interruption. This radio capability may additionally be used to provide cellular communication service to small cells associated with the relay and end points.

IPC: H03H21/00
Filed: 1997-06-23
Granted: 2003-01-14
Abstract: An adaptive system and method for reducing interference in a signal received from an array of sensors. Adaptive filters are used to generate cancelling signals that closely approximate the interference present in the received signal. The adaptive filter weights are converted into the frequency domain where the frequency representation values in a selected frequency range are truncated to avoid signal leakage involving narrow band signals. Decolorizing filters are used to produce the cancelling signals having a flat frequency spectrum. Normalized power difference is used to limit the operation of the adaptive filters to the case where there is some directional interference to be eliminated.

Abstract: Coatings of multiaxially oriented Thermotropic Liquid Crystalline Polymer (TLCP) are provided to elongated members. Suitable members include glass rods, glass fibers, pipes, beams, and other oval or polygonal members having an essentially regular cross section. Members of ceramic, plastic, or metal can also be coated. This extrusion is performed using a die having inner and outer mandrels capable of rotating in opposite directions. Concentricity between inner and outer mandrels of the die is maintained to assure uniform coating thickness. In order to produce a high level of multiaxial orientation at lower die rotational speeds, the die design may include spiraling feed zones on one or both facing surfaces of the inner and outer mandrels. The application of the multiaxially oriented coating provides superior impermeability to water vapor and oxygen, and increased strength to the elongated member in the axial direction.

Abstract: A conversion system enables a locomotive equipped with a conventional pneumatic brake control system to control braking on a train whose railcars each have electrically controlled pneumatic (ECP) brake equipment. The conversion system includes a power conversion mechanism, a signal conversion mechanism and two pressure reduction circuits. The power conversion mechanism converts battery voltage received from a power trainline of the locomotive to a predetermined nominal voltage. Made available to an ECP trainline that runs along the railcars, the predetermined nominal voltage is used to power the ECP brake equipment on each railcar in the train.      The signal conversion mechanism converts the pneumatic brake commands carried in the brake pipe of the locomotive into electrical brake commands corresponding thereto. Transmitted along the ECP trainline, the electrical brake commands control the ECP brake equipment on each railcar and the braking effort deliverable thereby. Part of the signal conversion mechanism, the first pressure reduction circuit is used to reduce the railcar brake pipe pressure to an emergency level when the brake pipe in the locomotive carries a pneumatic emergency brake command. The first pressure reduction circuit then pneumatically commands the ECP brake equipment to make an emergency brake application. The second pressure reduction circuit assures that the railcar brake pipe pressure reduces to the emergency level when the locomotive brae pipe pressure drops below a prespecified level.

Title: Displaying and interacting with an informational message based on an information processing system event
Inventor: KREYNIN VADIM
IPC: G06F9/44
Filed: 1998-10-16
Granted: 2002-01-01
Abstract: A method and apparatus that addresses the wait-time between an operator and a processing machine by providing the user information during waiting periods. A method is illustrated by the flow diagram (100) of the figure. A processor (101) renders a message (125) for the processor operator's education during times of processor latency (115) such as dialing onto any network such as the Internet. This wait time (117) is normally non-productive and therefore can be used in such a way as to be non-invasive. It is also understood that this time is short so as to make other actions such as getting up form the desk not attractive. Finally even if the wait-time was or became very short the present invention provides the first message (125) to the process operator, that has been frittered. This filtering is a balance of the message owner's willingness to out bid other messages, the time of the day, the location of the operator, and finally the operator's likes and dislikes.
