Abstract: Recording indicators for devices with cameras that provide protection from tampering so that the recording indicators cannot be easily disabled or masked. Recording indicators that are external to the camera lens and that emit visible light in an encrypted pattern are described. The device may process captured frames to detect the encrypted pattern; if the encrypted pattern cannot be detected, recording is disabled. In addition, modular accessories are described that the user has to attach to the device to enable recording; the presence of the modular attachment indicates to persons in the environment that they may be being recorded.

Abstract: Motion-based handoff control techniques are disclosed. For example, an apparatus may include a signal strength determination module, a motion determination module, and a handoff controller. The signal strength determination module generates signal strength information corresponding to the strength of a wireless signal received from a first wireless link. From this information, the motion determination module determines a motion characteristic of the apparatus. Based on the motion characteristic, the handoff controller performs handoff operations for a second wireless link. In this manner, handoff operations may be tailored to the operational characteristics of the apparatus. For instance, certain handoff operations may be halted when the motion characteristic indicates the apparatus having a substantially stationary position. Other embodiments are described and claimed.

Abstract: During a telephony session, a determination is made on a mobile computing device that one or more designated conditions exist by which radio interference generated from the mobile computing device is to be reduced. In response, a power state of a set of one or more components of the mobile computing device is lowered. This reduces radio interference from those components. The set of components are ancillary to the mobile computing device's ability to maintain the telephony session, so that the telephony session is not affected by the reduction of power to the components.
