International Classification:

H04B 138

US Classification:

455557, 455 111, 455 7, 455 9, 455318, 455416, 370277

Abstract:

A communications interface adapter facilitates both wired and wireless communications between crew members of a vehicle having a wired intercom and has an intercom communications circuit having an input/output port for providing electrical communication between the interface adapter and the wired intercom and also has a fixed radio transceiver. The fixed radio transceiver comprises a receive circuit for receiving radio communications and for communicating the received radio communications via the intercom communications circuit to the wired intercom of the vehicle and a transmit circuit for transmitting communications received via the intercom communication circuit from the wired intercom of the vehicle. A crew member is provided wired communications with the wired intercom when the crew members headset is in electrical communication with the wired intercom and is provided wireless communications with the wired intercom via the fixed radio transceiver and the crew members portable radio transceiver when the crew members headset is not in electrical communication with the wired intercom.

Raytheon Company - Walham MA

International Classification:

H04W 28/02

US Classification:

370236

Abstract:

Methods and apparatus for transmitting, from a radio, over a router-to-radio interface, a first transmission-on signal indicating to a router that data packets can be sent to the radio for transmission in a network, and transmitting, from the radio over the router-to-radio interface, a first transmission-off signal indicating to the router that data packet transmission should be suspended until receipt of a second transmission-on signal, wherein the first transmission-on signal and the first transmission-off signal are generated in a network layer of the seven-layer OSI model.

Assignee:

Raytheon Company - Waltham MA

International Classification:

H04L 12/56

US Classification:

370392

Abstract:

In one aspect, a method Includes receiving a data packet at a routing node that includes a processor. The method also includes determining at least one value for the data packet, selecting a routing table from a plurality of routing tables stored at the routing node in response to the at least one value for the packet and forwarding the data packet in response to the routing table selected. Each routing table is associated with a respective one cost function.

International Classification:

H05K 330
H05K 1302
H05K 1304
H05K 1308

US Classification:

29834

Abstract:

A vertical wafer compact flip chip feeder device includes a loading station for providing a loading location where a flip chip wafer having first and second planar surfaces is received such that the first and second planar surfaces are substantially perpendicular to a first plane. The flip chip feeder device further includes a pick-up station for providing a pick-up location where individual flip chips are retrieved from the flip chip wafer. A wafer translating assembly translates the flip chip wafer between the loading and pick-up stations with the first and second planar surfaces of the flip chip wafer remaining substantially perpendicular to the first plane. A chip pick-up assembly retrieves the individual flip chips from the flip chip wafer at the pick-up station and flips the individual flip chips to a flipped position such that first and second planar surfaces of the individual flip chips are substantially parallel with the first plane.

Appl. No.:

8/618641

Inventors:

Steven Davidson - Boston MA

International Classification:

G03B 2114

US Classification:

353119

Abstract:

A portable video frame system. A projector such as an LCD lightweight projector is removably mounted to a triangular top frame portion. Support brackets are removably mounted to this top frame portion and to a rear frame portion. The rear frame portion is itself supported on a base having sufficient weight to support the entire assembly. Optionally, at least a portion of the weight is provided by necessary ancillary equipment, such as speakers. A conventional snap screen snaps onto the rear frame portion, and is always the same distance from the projector. The entire assembly can be readily disassembled and moved to a different location.
