Abstract: Incident light filter or cap assembly adapted to be attached to a mobile device equipped with a camera and software to measure light levels.

Abstract: A mouse with multi button functionality is disclosed. The mouse includes a housing that surrounds the internal components of the mouse. The housing includes at least a first member and a second member, each of which forms a substantial portion of the housing. The first member moves relative to the second member so as to implement at least one of the multiple button functions of the mouse.

Abstract: According to one aspect of the invention, a movable cursor control device is provided for controlling a cursor on a display screen of a digital processing system. One exemplary cursor control device comprises a housing, an electromagnetic emitting device coupled to the housing, and an electromagnetic detector coupled to the housing. The electromagnetic detector detects reflections of signals emitted from the electromagnetic emitting device and determines when the housing has been lifted from a surface. In another aspect of the invention, an exemplary method is provided for controlling a cursor on a display screen of a digital processing system. The exemplary method includes holding the cursor relative to an object on the display screen using a cursor control device activated by a user, detecting that the user no longer activates the cursor control device, and detecting that the user has lifted the cursor control device from a surface when the cursor control device is no longer activated by the user.
