Abstract: A control device includes a processor and a control button. The control button includes a key and an analog sensor coupled to the processor. The key is configured to be moved in a first direction and a second direction, which is substantially opposite from the first direction. The analog sensor is configured to detect an amount of movement of the key in the first direction and the second direction and send a control signal to the processor to indicate the amount of movement. Based on the control signal, the processor is configured to control zoom of a graphical object displayed on a computer monitor at a rate that is based on the amount of movement.

Abstract: An input device for inputting commands to a host computer includes a base. An upper housing defines a plurality of control buttons for inputting commands to the computer. The base and upper housing are movably coupled to each other to enable the mouse to be placed in a collapsed position and a raised position. A release button is configured to actuate and facilitate raising of the mouse from the collapsed position to the raised position, the raised position placing the mouse a suitable state for inputting commands to the computer using the control buttons.

Abstract: A super-capacitor-powered device is quickly recharged from an energy buffer incorporated in a USB cradle or USB dongle. That USB energy buffer itself is slowly refilled while it is connected to a USB port. The super-capacitor can be in parallel to a battery. In one embodiment, a facilitated battery changer is provided. A battery swap is performed with a recharged battery in a charger having two battery slots.

Abstract: Embodiments of the present invention provide a presentation device that is simple to control for managing time and providing presentation instruction to a host device to make a presentation. In one embodiment, a presentation device is controlled by a user for providing presentation instruction to a host device to make a presentation. The presentation device comprises a timer button configured to be activated by a user to select an end time for a presentation, wherein each time the timer button is activated, a time interval between a current time and the end time is increased by a preset time increment. A timer module is configured to determine the time interval between the current time and the end time for the presentation as time passes; and a display configured to display the time interval between the current time and the end time for the presentation as time passes.

Abstract: A peripheral device station couples two or more peripheral devices with a host computer system. The station includes two or more peripheral device interfaces, a power unit, a communication intermediary, and a host interface. At least one peripheral device interface includes a communication connection and a power connection. The power unit couples with the power connection and provides an electrical charge for charging a power source of a peripheral device. The communication intermediary couples with the communication connection and provides a communication coupling between a peripheral device and the host computer system. The host interface couples with and communicates with the host computer system.
