摘要： Methods and apparatuses are provided for determining a transmission power cap for one or more devices based at least in part on pathloss measurements to one or more access points received from the one or more devices. A common transmission power cap can also be computed for assigning to devices communicating with an access point, and the transmission power cap for a given device can be adjusted when the transmission power is at or a threshold level from the common power cap to conserve signaling in the wireless network. Adjustment of the transmission power cap can additionally or alternatively be based on a received power at an access point related to signals from the device, an interference report from one or more access points, and/or the like.

摘要： A converter includes a transformer having a primary winding, a secondary winding and an auxiliary winding, a first switching device for connecting an input voltage to the primary winding of the transformer, an output circuit connected to the secondary winding, a controller, and an integrated active clamp and primary bias circuit. The integrated active clamp and primary bias circuit includes the auxiliary winding and a second switch providing a bias voltage to the controller to alternately operate the first and second switches between conductive and non-conductive states. When the first switch is conductive the second switch is nonconducting and power is transferred from the primary winding to the output circuit via the secondary winding and from the auxiliary winding to the controller. When the first switch is nonconducting, the second switch is conducting and the voltage across the primary winding is clamped.

摘要： Antennas are provided for electronic devices such as portable computers. An electronic device may have a housing in which an antenna is mounted. The housing may be formed of conductive materials. A dielectric antenna window may be mounted in the housing to allow radio-frequency signals to be transmitted from the antenna and to allow the antenna to receive radio-frequency signals. Near-field radiation limits may be satisfied by reducing transmit power when an external object is detected in the vicinity of the dielectric antenna window and the antenna. A proximity sensor may be used in detecting external objects. A parasitic antenna resonating element may be interposed between the antenna resonating element and the dielectric antenna window to minimize near-field radiation hotspots. The parasitic antenna resonating element may be formed using a capacitor electrode for the proximity sensor. A ferrite layer may be interposed between the parasitic element and the antenna window.

摘要： A method for reactivating a telematics device configured to make a data call via a roaming partner of a service provider is disclosed. The service provider has an authentication bypass feature which uses an authentication bypass key common to the telematics device and the service provider to allow the telematics device to make a data call without authentication. The method comprises setting the authentication bypass key on a server of the service provider equal to a previous authentication bypass key, wherein the previous authentication bypass key was used by the authentication bypass feature prior to deactivation of the telematics device. The method includes setting the authentication bypass key on the telematics device equal to the previous authentication bypass key. The method further comprises commencing the data call through the roaming partner by sending the authentication bypass key to the service provider from the telematics device via the roaming partner.
