摘要:
In one embodiment of an optical pointing device, an illumination system includes a plurality of light sources. Each light source is characterized by a unique set of illumination characteristics. Illumination characteristics include impinging angle, light wavelength, light homogeneity, and the like. A sensor receives electromagnetic energy originating at the light source to scan an imaged area. The sensor measures performance indexes associated with the light sources, which depend on the illumination characteristics. The sensor includes an imaging module, which may include passive filters, and control logic, which includes at least a DSP module and a light sensor selection module. Another embodiment includes additional signaling light sources that do not interfere with the illumination system and are for signaling to the user. A method to select the most adequate light source for any given surface is based on measured performance indices.

A system and method of manufacturing directed to an attachment system for use in an optical device. The attachment system mechanically couples a light source to an illumination lens using an attachment device. The attachment device can be an auto-centering device for reducing positional errors in a light beam emitted from the light source.

A system, method, and method of manufacturing directed to an optical device with increased accuracy in tracking ability. The increased accuracy can be achieved by using a multiple sensor system. A second sensor is added to the optical device. The second sensor increases the probability of obtaining a high quality image. Thus, the tracking ability of the device can be performed with greater accuracy over a single sensor device. The second sensor can also perform additional functions.

A system, method, and method of manufacturing directed to an optical device with an efficient optical illumination. The optical illumination can be provided by tilting a light source and using a refractive lens to direct the light onto a surface. Alternatively, the optical illumination can be provided using total internal reflection with a conical light pipe and a curvatured entrance and exit surface.

A universal charger which can charge multiple electronic devices, such as a keyboard, mouse, remote control, etc. In one embodiment, a user is directed to a website over the internet to a site containing charging profiles for multiple devices. The user selects the particular devices the user will want to charge and downloads the charging profiles. The charging profiles are provided to the universal charger device. A number of mechanisms are provided to identify the device, such as wireless or wired communication with the device or reading an RFID tag in the device. Various embodiments are disclosed, including having smaller devices (remote control, mouse) moved to the charger and the charger move to larger devices (keyboard). Also, various indicators are shown to indicate which device needs charging, and various lighting schemes show the amount of charging.

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.

A 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.
