Patent ID: 7161578

Claim:
A universal presentation device comprising: an electronic control device configured to communicatively couple with a computer system to provide a control mechanism for the computer system; a radio-frequency transmitter configured to communicatively couple the electronic control device with the computer system; and a coherent light source configured to provide a coherent light beam for pointing the coherent light beam on an object; a user-operable switch having a first state configured to select operation of the electronic control device, a second state configured to select operation of the coherent light source, and a third state configured to select operation of the electronic control device and the coherent light source for substantially simultaneously operating for combined operation of the electronic control device and the coherent light source, which are dimensioned to form a substantially unitary device when at least one of the electronic control device or the coherent light source is operational, a first housing portion including the electronic control device, a first power source, and a first electrical contact for the first power source; and a second housing portion including the coherent light source, a second power source, and a second electrical contact for the second power source, wherein the first housing potion and the second housing portion are separable and combinable, if the first housing portion and the second housing portion are combined, the first and second electrical contacts are configured to contact and the first power source and the second power source are configured to provide a single power source configured to be shared by the electronic control device and the coherent light source.
