Abstract: A mobile wireless communications device may include a housing, a wireless transceiver carried by the housing, an audio transducer carried by the housing, and a novelty voice alteration processor carried by the housing and coupled to the wireless transceiver and the audio transducer and configured to alter voice communications. For example, the novelty voice alteration processor may comprise a memory and a processor cooperating therewith to alter the voice communications.

Abstract: An optical trackpad module is described herein. The module includes a light source and a trackpad that is optically coupled to the light source such that light from the light source can reach the trackpad. The trackpad is configured to receive an input object. The module also includes a sensor array that receives at least some of the light from the light source that is reflected off the input object. The sensor array is divided into sub-sections, and each sub-section corresponds to a portion of the trackpad. In addition, each sub-section detects at least translational movement of the input object on the corresponding trackpad portions to enable detection of rotational motion of the input object on the trackpad.

Abstract: An identification system includes a mobile communications device and an accessory having a connection plug with a conical tip. An insulating ring extends about the conical tip portion to define a tip detection contact. The device includes a tip detection pin positioned adjacent to an interior end portion of a connection socket on the device. The tip detection pin engages the tip detection contact to enable identification of the accessory by the mobile communications device. An improved accessory is for use with a mobile communications device. A method identifies an accessory which has its connection plug inserted into a socket on a mobile communications device.
