Abstract: Aspects of the disclosure relate to a handheld device equipped with arrays of force sensors located along both sides of the device that can provide a novel user interface for operating the device. The sensors can be configured to recognize various grip patterns, gestures, and biometric information of a user operating the device. Using the arrays of force sensors in addition to a touchscreen, a new paradigm for operating a handheld device is provided.

Abstract: Handheld devices using an array of stainless steel electrodes located on an edge and/or back of the handheld devices for acquiring electrodermal activity are provided. The stainless steel electrode array may allow for the skin conductance level (SCL) or skin conductance response (SCR) on an individual to be measured and collected. The skin conductance signal may be related to sympathetic nervous system activity which is a major component of human emotion, known as arousal, or emotional intensity such as anxiety, stress, fear, or excited, etc.

Abstract: A wireless communication device receives audio data from a base station via a radio frequency (RF) communication link (i.e., a forward link) and transmits audio data to the base station via the RF communication link (i.e., a reverse link). The wireless communication device uses the inherent functionality of the reverse link, including an audio input device (120) to determine whether the wireless communication device is operating in a high noise environment. A signal analyzer (124) analyzes the audio signal on the reverse link and determines whether the ambient noise level exceeds predetermined threshold. If so, the signal analyzer (124) activates a filter (126) to filter the audio signal being provided to an audio output transducer (122). Band limiting the audio signal provided to the audio output transducer (122) improves intelligibility of the audio signal in the presence of noise.
