Abstract: A first mobile station (102) can be wirelessly linked to a second mobile station (104). A physical location of the second mobile station with respect to a physical location of the first mobile station can be determined. A first player (112) using the first mobile station can be presented an icon (402) representing a second player using the second mobile station. The icon can be presented from a perspective of an eye level view. At least one targeting icon (410) can be presented to the first player to facilitate targeting of the second player. A physical stimuli can be generated from the first mobile station and/or the second mobile station in response to a simulated weapon activation on the first mobile station. The physical stimuli can be a narrowly focused ultrasound beam (302) modulated to generate an audible sound when a propagation of the ultrasound beam is disrupted by a physical object.

Abstract: An RF power fairness method (26) receives a request for supplemental channel resources (160). If sufficient supplemental channel resources (time slots and data rates) are not available, the original request is modified (166). If there is multiple call activity on the supplemental channel, RF power is calculated for each of the simultaneous calls on the shared channel (202, 208). If successful time slots and data rates are found, a grant message is returned from the time slot manager (26) to the base station (164, 170, 180). If insufficient time slots and data rate power are determined, a deny request message is transmitted to the base station (184).

Abstract: A wireless communications device detects a change in its residual energy status, and transmits the residual energy status across a wireless communications network to a remote device that coordinates communications in the wireless communications network. For example, the remote device may be a piconet coordinator (PNC) in an IEEE 802.15.3 network, or a master device in a Bluetooth network. A wireless communications device that coordinates communications in a wireless communications network (the coordinator) transmits one or more first handover commands to one or more remote devices upon the occurrence of a triggering event. Based on responses to these first commands, the coordinator selects a remote device for coordinating future communications in the wireless communications network.

Abstract: A mobile communication terminal includes at least one function key which demonstrates improved resistance to vibration. This is achieved by positioning a spacer between the function key and an associated switch, which in the case of a mobile terminal may be a tact switch. The spacer may be made from an elastic material which compresses when inserted between the switch and function key. Alternatively, the spacer may be made from a rigid material. Also, the spacer may extend from one or more layers of a keypad and may be made to bend into proper orientation adjacent a side button on the terminal. By eliminating the clearance gap between the function key and switch, undesirable noise is prevented and improved stability to vibration is demonstrated. Also, a better feel to as user is achieved as a result of the reduction or elimination of this clearance gap.
