Abstract: A mobile station (110) that includes a first network adapter (210) configured to communicate over a first communications network (120) and a second network adapter (220) configured to communicate over a second communications network (130). The mobile station also includes a multimodal processing module (250) that generates a busy notification in response to receiving a call via the second network adapter while the mobile station is engaged in a first call via the first network adapter. The busy notification can be automatically generated by the multimodal processing module in response to the second call being received, or generated in response to receiving a user input entered in response to the second call has been received.

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 electronic controller apparatus (30) having an input device (36) coupled to a display (34) can include a motion detector (40) and a means (42, 44, 46, 48, and 50) for maintaining the display in a predetermined orientation relative to a user of the electronic device and regardless of the movement of the input device. The movement of the input device causes a signal to vary in the electronic controller apparatus. The electronic controller can be a hand held device such as a game controller, a personal digital assistant, a cellular phone, a remote control device, or a gaming adaptor for a personal digital assistant or for a cellular phone. The means for maintaining the display in the predetermined orientation can use gravity to maintain the predetermined orientation or alternatively use electronic sensors (104 and 105) and motors (108 and 110) to maintain the predetermined orientation of the display.
