Abstract: A process and apparatus for managing remote devices, for example subscriber mobile devices in a mobile communication network. Apparatus, such as a device management server, transmits a device management initiation message to a managed device such as a mobile device operating within a mobile network. If the message is not received or unsuccessful in establishing a device management communication session, another device management initiation message may be sent. If the device management session may still not begin, the device management server sends a device management client reset message to the managed device. After expiration of a client reset timer, an additional device management initiation message is transmitted.

Abstract: The present disclosure provides devices and techniques for dynamically adjusting the bias voltage (V) levels (e.g., low level gate voltage (VGL) and high level gate voltage (VGH)) for display screens made with thin-film transistor (TFT) technology based on a display run time. Thus, as the positive bias temperature stress for the TFTs increases over the course of the display lifetime, features of the present disclosure adjust the bias voltage levels to maintain operation margin (e.g., the ratio between the high level gate voltage (VGH) value and the voltage value which the display can maintain with normal operation). By dynamically adjusting the bias voltage levels, the TFT displays of the present disclosure consume lower power than their conventional counterparts and improve the lifetime of the display itself.
