Abstract: A rechargeable battery pack can provide power to a device that also accepts at least one standard non-rechargeable battery. The rechargeable battery pack may include a housing for housing at least one battery cell and recharging circuitry. The at least one battery cell and the recharging circuitry can be housed substantially within the housing. The recharging circuitry can be coupled with the at least one battery cell. The recharging circuitry can be configured to charge the at least one battery cell when the battery pack is inserted into the device that also accepts at least one non-rechargeable battery. The rechargeable battery pack may further include a protection circuit coupled with the recharging circuitry.

Abstract: An apparatus for detecting writing pressure is comprised of a carrier. A mode selection device coupled to the carrier is operable to select writing modes. A switch coupled to the carrier is operable to move between a first state and a second state in response to writing pressure coupled to the switch. An actuator coupled to the carrier is configured to actuate the switch in response to pressure applied to the actuator in response to writing.

Abstract: A user interface device for controlling an audio visual system. In one embodiment, a device for interfacing with an audio/visual system includes a sensor mat including a surface and operable to be disposed on a substantially flat floor. The sensor mat is further operable for generating electrical signals responsive to physical interactions of a user with the surface. The interface device also includes an electronic control unit including circuitry for coupling to the mat, the electronic control unit for detecting the physical interactions of the mat and the electronic control unit operable to be placed on the substantially flat floor. The interface device further includes an elongated shaft having a first end and a second end and physically coupled to the electronic control unit via the first end and extending laterally therefrom. The second end of the elongated shaft is operable to be displaced in various directions by interactions with both hands of the user.

Abstract: A controller, a method of interacting with a computer-implemented program, and a method for modifying controller functionality. In one embodiment of the present invention, a controller includes a first member and a second member movably coupled with the first member, wherein a movement of the second member with respect to the first member is operable to transform the controller from a first configuration to a second configuration. The controller also includes a plurality of input devices coupled with at least one of the first member and the second member. Additionally, a processor is coupled with and operable to change an operation state of the plurality of input devices and available controller functionality upon detecting the transformation from the first to the second configuration.
