摘要:
A connector apparatus which is useful in testing electrical circuits where it is desired to mate test equipment to conventional integrated circuit sockets is disclosed. Spring probes make electrical contact with integrated circuit socket pins. J-shaped members of the apparatus have fingers which engage conventional integrated circuit sockets between the socket and a circuit board to clamp the apparatus to the socket. Fasteners lock the apparatus in this clamped position.

A method and system for communicating header compression layer control messages. Header compression control messages are generated by a header compression layer (302) and are sent through at least one link layer data packet by a link transport communications protocol layer (304) to a remote receiver (104). The link transport communications protocol layer (304) monitors receipt of link layer data packet acknowledgements that are received from the link transport communications protocol layer (304) of the remote receiver (104) for the at least one link layer data packet. The link transport communications protocol layer (304) determines successful transmission of the header compression control message and provides, to the header compression layer (302), an indication of successful header compression control message transmission.

A process for forming a laminate with capacitance and the laminate formed thereby. The process includes the steps of providing a substrate and laminating a conductive foil on the substrate wherein the foil has a dielectric. A conductive layer is formed on the dielectric. The conductive foil is treated to electrically isolate a region of conductive foil containing the conductive layer from additional conductive foil. A cathodic conductive couple is made between the conductive layer and a cathode trace and an anodic conductive couple is made between the conductive foil and an anode trace.

Methods are provided for managing a multitude of objects displayed on a touch screen by selectively associating objects using free-form input gestures. A method comprises displaying a plurality of objects on the touch screen, identifying a first free-form input on the touch screen overlying a first object of the plurality of objects, and identifying a second free-form input gesture on the touch screen overlying a second object of the plurality of objects. The first object and the second object are associated when the first free-form input and the second free-form input each substantially correspond to the same input gesture.

A method (300, 400) for communicating RF signals from a mobile station (100). The method can include detecting whether the mobile station or a first antenna (105) of the mobile station is proximate to an object. Responsive to detecting that the mobile station or the antenna is proximate to the object, RF energy being communicated by the mobile station can be distributed among the first antenna and at least a second antenna (110). Distributing the RF energy can include equally distributing the RF energy among the first antenna, the second antenna and/or any additional antennas. Distributing the RF energy also can include unequally distributing the RF energy among the first antenna, the second antenna and/or any additional antennas.

A communication system provides secure communication between two nodes in a self-organizing network without the need for a centralized security or control device. A first node of the two nodes is provisioned with one or more security profiles, auto-discovers a second node of the two nodes, authenticates the second node based on a security profile of the one or more security profiles, selects a security profile of the one or more security profiles to encrypt a communication session between the two nodes, and encrypts the communication session between the two nodes based on the selected security profile. The second node also is provisioned with the same one or more security profiles, authenticates the first node based on a same security profile as is used to authenticate the second node, and encrypts the communication session based on the same security profile as is used for encryption by the first node.

A method and apparatus for managing common and application specific presence information, wherein the apparatus programs a computer to perform the method, which includes: receiving a publication message comprising presence information from a presentity; partitioning the presence information into common presence information and application specific presence information; storing the common presence information in a common presence information database, wherein authorization for access to the common presence information database is controlled by the presence server; and forwarding the application specific presence information to an external application, wherein the external application controls storage of the application specification presence information and authorization for access to the application specific presence information.
摘要:
Methods for establishing secure point-to-point communications in a trunked radio system include receiving, at a trunking controller, a request from a source endpoint for a traffic channel for confidential communications between the source endpoint and a destination endpoint using a shared unique first symmetric key. The trunking controller provides keying material related to the symmetric key over the secured control channel to at least one of the source or destination endpoints and assigns a traffic channel. Moreover, in response to the request, the controller assigns a traffic channel. The keying material enables the unique first symmetric key to be securely established between the source and destination endpoints.

A method and apparatus for optimizing the mobile media received by a mobile device is disclosed. The apparatus operates with a radio access network, a mobile device operating in the radio access network, and a media server providing mobile media data to the mobile device wherein the mobile device connects to the media server using the radio access network. The apparatus includes a optimization application server coupled to the radio access network. The optimization application server includes positioning indexed performance information based on the positioning information and performance of a plurality of mobile devices operating in the radio access network. The optimization application server triggers adjustments to a parameter at least one of the radio access network, the mobile device and the media server by comparing the location of the mobile device in the radio access network to the optimization application server and sending a message to the radio access network to adjust the parameter.
摘要:
Communication devices and methods for transmitting and receiving a wideband signal using aggregated discontiguous narrowband channels in a band are presented. During transmission, a fold point is determined in which symmetric free channels are sufficient to transmit the signal. The signal is then synthesized by aggregating the data in the channels and transmitted using the fold point as the up-conversion modulation frequency. During reception, information regarding which channels are being used to provide data signals and which channels are occupied by interferers is received. This information is used to determine one or more fold points as the down-conversion modulation frequencies. The fold points are selected such that an image of each interferer falls on an unoccupied channel or a narrowband channel occupied by another interferer.
