Patent number: 8515500Abstract: A scheme is provided for conserving power in client terminals and/or reducing latency in wireless systems by using a proxy device. The client terminal may have a primary communication interface for communications with an access node and a secondary communication interface to communicate with the proxy device. The client terminal may indicate to the access node a short cycle rate for monitoring its signaling/control channel(s). The client terminal may the power off its primary communication interface without informing the access node. Prior to powering off its primary communication interface, the client terminal may assign the proxy device to act as its proxy and monitor the signaling/control channel with the access node. The proxy device monitors the signaling/control channel(s) according to the indicated short cycle rate. Upon detection of a message for the client terminal, the proxy device forwards the message to the client terminal via a secondary communication interface.Type: GrantFiled: September 16, 2010Date of Patent: August 20, 2013Assignee: QUALCOMM IncorporatedInventors: Soumya Das, Samir S.

Patent number: 8351342Abstract: A roaming emulator provides a tool for emulating system determination for monitoring the operation of a wireless communication device (WCD) during system determination. A signal monitoring program and service selection protocol are stored, and a signal emulation module provides a signal emulation output in accordance with a predetermined set of data. A processing module performs a simulation of a service selection procedure based on the service selection protocol and performed in accordance with the signal monitoring program and the signal emulation output. A result of the service selection is provided by an output module. The emulator can provide emulated system scanning based on geographical or market location, and can emulate scenarios when channels from neighboring systems or markets “bleed” into the RF environment of the WCD.Type: GrantFiled: June 23, 2006Date of Patent: January 8, 2013Assignee: QUALCOMM IncorporatedInventors: Rajeev D.

Patent number: 8064904Abstract: A general global gateway (GGG) internetworks between a first network and a second network so that a mobile station having a subscription in a first network can roam into a second network and be authenticated to use the second network. The GGG obtains authentication parameters from the mobile station and determines whether the authentication parameters satisfy GGG authentication criteria. If it does, then the GGG accesses the first network and stores authentication information from the first network for subsequent accesses to the first network by the mobile station.Type: GrantFiled: March 18, 2004Date of Patent: November 22, 2011Assignee: Qualcomm IncorporatedInventors: Nikhil Jain, Andrew T.

Patent number: 7923688Abstract: An optical detector pixel element. The novel pixel element includes a metallic substrate having a plurality of resonant apertures, each aperture adapted to resonantly transmit electromagnetic energy in a distinct frequency band, and a plurality of detectors adapted to detect the energy transmitted by the apertures. Each aperture is adapted to collect energy incident on an area larger than the aperture and focus the energy into a smaller, localized region in which one or more of the detectors is placed. The plural apertures are positioned such that they collect energy incident on a substantially common area, but are of different sizes such that they are resonant to different frequencies. Energy in different frequency bands are therefore funneled through different apertures. In an illustrative embodiment, several identical pixel elements are joined together to form an array.Type: GrantFiled: October 31, 2007Date of Patent: April 12, 2011Assignee: Raytheon CompanyInventors: Daniel J.

Patent number: 7800067Abstract: Electronically tunable and reconfigurable hyperspectral IR detectors and methods for making the same are presented. In one embodiment, a reconfigurable hyperspectral sensor (or detector) detects radiation from about 0.4 ?m to about 2 ?m and beyond. This sensor is configured to be compact, and lightweight and offers hyperspectral imaging capability while providing wavelength agility and tunability at the chip-level. That is, the sensor is used to rapidly image across diverse terrain to identify man-made objects and other anomalies in cluttered environments.Type: GrantFiled: December 1, 2009Date of Patent: September 21, 2010Assignee: HRL Laboratories, LLCInventors: Rajesh D.

Patent number: 7795859Abstract: Low cost millimeter wave imagers using two-dimensional focal plane arrays based on backward tunneling diode (BTD) detectors. Two-dimensional focal arrays of BTD detectors are used as focal plane arrays in imagers. High responsivity of BTD detectors near zero bias results in low noise detectors that alleviate the need for expensive and heat generating low noise amplifiers or Dicke switches in the imager. BTD detectors are installed on a printed circuit board using flip chip packaging technology and horn antennas direct the waves toward the flip chip including the BTD detectors. The assembly of the horn antennas, flip chips, printed circuit board substrate, and interconnects together work as an imaging sensor. Corrugated surfaces of the components prevent re-radiation of the incident waves.Type: GrantFiled: July 15, 2009Date of Patent: September 14, 2010Assignee: HRL Laboratories, LLCInventors: Jonathan James Lynch, James H.

Patent number: 7542451Abstract: A network operator identifier is used to uniquely identify each network operator to support international roaming. The network operator identifier includes (1) a Mobile Country Code (MCC) that identifies the country in which a network operator belongs and (2) a Network Operator Code (NOC), which may be a Mobile Network Code (MNC), that distinguishes network operators within a given MCC. Each network operator is assigned a unique combination of MCC and NOC that distinctly identifies the network operator, and the network operator identifier can be stored in a single entry in a preferred roaming list. The base stations of each network operator broadcast the network operator identifier in signaling messages. A mobile station receives a signaling message from a base station, obtains the network operator identifier, searches its preferred roaming list for an entry with the network operator identifier, and determines whether or not the current CDMA network is accessible.Type: GrantFiled: June 27, 2003Date of Patent: June 2, 2009Assignee: QUALCOMM IncorporatedInventors: Rotem Cooper, Alejandro Holcman, Andrew T.
