User interface methods and systems for providing force-sensitive input

Abstract: Methods and systems implement touch sensors or force sensitive materials disposed on the case of a computing device in order to enable user input gestures to be performed on portions of the device case. The force sensitive elements may generate an electrical signal in response to a gesture, such as a tap, squeeze, swipe or twist. The properties of the generated electrical signal may be compared to various reference templates to recognize particular input gestures. The force sensitive elements may operate in conjunction with more traditional input methods, such as touch-screen display and electromechanical buttons. By enabling user input gestures on the case of computing devices, the various aspects permit one hand operation of the devices including intuitive gestures that do not require the users focused attention to accomplish. Thus the various aspects may enable users to utilize their computing devices in situations not suitable to conventional user input technologies.

Method and apparatus for determining location of a base station using a plurality of mobile stations in a wireless mobile network

Abstract: A method and apparatus for determining a position of a base station in a wireless communication network that includes a mobile station in communication with base stations. A BTS calibration server is networked with the base stations. A BTS calibration program is programmed into a group of mobile stations that have position location capabilities. Using the BTS calibration program, calibration information may be requested by the BTS calibration server, or a session may be initiated by the mobile station. The BTS calibration program also provides privacy features that allow user of the mobile station to prevent it from being used for base station location. If authorized, the BTS calibration program determines the position of the mobile station, and provides calibration information, such as position and base station phase measurements, to the server. The calibration information may be used to calibrate the base station almanac.

User interface gestures and methods for providing file sharing functionality

Abstract: Methods and devices provide a gesture activated file sharing functionality enabling users to share files with other nearby computing devices. The file sharing functionality may include establishing wireless links with nearby devices and determine their relative locations. The computing device may detect a file sharing gesture and transmit files to or request files from a nearby device in response to the gesture. Base on gesture parameters, e.g., direction, speed and shape, and computing device attitude parameters, e.g., tilt angle and pointing direction, the computing device may identify a targeted device to which a file may be transmitted. The computing device may request user verification of the identified device and send a request to transmit files to the targeted device. The computing devices may transmit files using networks and addresses provided over the device-to-device communication links.

Methods and devices for interworking of wireless wide area networks and wireless local area networks or wireless personal area networks

Abstract: Embodiments describe registration in a wireless communication system. A method includes wirelessly transmitting over a WWAN a first registration message from a mobile device, wirelessly transmitting through the WWAN a second registration message to a WLAN access point and receiving at the mobile device access through the WLAN access point. According to another embodiment is a method for constructing a self-configuring ad-hoc network. The method can include receiving a GPS coordinate from a WWAN channel node at a management system and creating an initial topography based at least in part on the GPS coordinate to achieve a network connectivity with diverse routes between a plurality of nodes.

Diversity transmission modes for mimo ofdm communication systems

Abstract: Techniques for transmitting data using a number of diversity transmission modes to improve reliability. At a transmitter, for each of one or more data streams, a particular diversity transmission mode is selected for use from among a number of possible transmission modes. These transmission modes may include a frequency diversity transmission mode, a Walsh diversity transmission mode, a space time transmit diversity (STTD) transmission mode, and a Walsh-STTD transmission mode. Each diversity transmission mode redundantly transmits data over time, frequency, space, or a combination thereof. Each data stream is coded and modulated to provide modulation symbols, which are further processed based on the selected diversity transmission mode to provide transmit symbols. For OFDM, the transmit symbols for all data streams are further OFDM modulated to provide a stream of transmission symbols for each transmit antenna used for data transmission.
