Abstract: An electronic pointing device for a computer comprising a housing and an electronic module to detect the relative displacement over an external surface and transmit it to the computer wherein the housing comprises means to adjust the total weight of the device. According to the invention, the user can freely (within certain limits) adjust the weight depending on his wishes. In one embodiment, the pointing device is a mouse.

Abstract: A mouse having an adjustable body size includes a mouse body having a first side and a second side; and a palm rest coupled to the mouse body, wherein the palm rest has a first size and the palm rest is configured to be removed from the mouse body to fit another palm rest to the mouse body having a second size that is different from the first size. The palm rest includes a first arm, a second arm, and a body portion that couples the first arm and the second arm. The first arm and the second arm are respectively coupled to the first side and second side of the mouse body.

Abstract: A control device for use on a working surface includes a bottom housing configured to be placed on the working surface; a top housing coupled with the bottom housing, the top housing including at least one key; an actuator disposed between the bottom housing and the top housing and coupled with the key; a switch disposed between the bottom housing and the top housing, wherein the switch is activated via application of an actuation force to the key; and an adjustment means configured to enable a user to adjust the actuation force required to activate the key.

Abstract: An optical displacement system for an input device of a host device includes a substrate; an aperture; a light source and a sensor chip attached to the substrate, an illumination optics to direct the light emitted by the light source to a surface of an object. The sensor chip is configured to receive at least part of the light emitted by the light source after the light has been scattered/reflected on the surface of the object.
