Abstract: A character recognition system includes, but is not limited to, a touchpad including a touch sensing surface for generating a first signal in response to a touch, the first signal corresponding to a location of the touch on the touch sensing surface, the touchpad further including a topographical feature associated with the touch sensing surface, the topographical feature configured to guide a touching member in a predetermined pattern along the touch sensing surface, the predetermined pattern corresponding with a predetermined set of characters. The system also includes an output device for communicatively coupling with a controlled device. The system further includes a processor communicatively coupled with the touchpad and the output device. The processor receives the first signal, detects a pattern of the touch, generates a second signal corresponding to the pattern, and instructs the output device to output the second signal.

Abstract: Wireless earphone systems provide earphones configured to be supported entirely by the ear canals of the wearer and to provide stereophonic reproduction of sound to the wearer based on a two-channel stereophonic signal from a transceiver that is attachable to a device. Certain systems include earphones configured such that channel reception can be switched between the earphones. Certain systems include an earphone that includes: a housing; a ground plane comprising circuitry; and a multi-segmented antenna configured to receive a signal from a transceiver, wherein the antenna and the ground plane are disposed within the housing, wherein the antenna is substantially parallel to the ground plane, and wherein the antenna and the ground plane are separated by a distance.
