20090135140 | SYSTEM AND METHOD FOR ACCURATE LIFT-DETECTION OF AN INPUT DEVICE - Various systems and methods are employed for lift-detection. Beam triangulation can be used, and in one embodiment, an optical lift detection module is separate from the optical tracking module. In one embodiment, a capacitive lift detection technique is used. A capacitor is built into the bottom case of the mouse. When the mouse is resting on a surface, the surface material serves as a dielectric for the capacitor, while air serves as the dielectric when the mouse is lifted. This dielectric change leads to a change in the capacitance value, leading to detection of lift. In one embodiment, a capacitor with an easily compressable material inserted between the two electrodes is used. In another embodiment, a mechanical plunger with an elastic membrane is used for lift detection. Lift detection can be tunable and/or customizable. The actual height of the life can be detected, rather than simple on-off notifications. | 05-28-2009 |
20110025311 | MAGNETIC ROTARY SYSTEM FOR INPUT DEVICES - Embodiments of the present invention include a roller for an input device, where the roller's absolute angular position is measured by a magnetic encoder. A magnet is attached to the roller, possibly inside the roller so as to make the embodiment more compact. In one embodiment, the magnetization is simple and low cost. Further, tight tolerances are not required, and such a system is easy to manufacture. In one embodiment, the sensor is covered by any non-ferromagnetic material, to protect it from foreign particles, and to reduce ESD. In one embodiment, the wheel consumes much less power than conventional wheels in input devices. In one embodiment, the tilting of the wheel is measured using the same sensor that is used for measuring the rotation of the wheel. In one embodiment, a ratcheting feel provided to the user when rotating the wheel is synchronized with the rotation signal. | 02-03-2011 |

20130282932 | MULTI-HOST WIRELESS INPUT DEVICE - Embodiments of the invention are directed to input devices configured for use with computing devices. The present invention relates to methods and devices for establishing, maintaining and managing, wireless connections with between an input device and one or more host devices that the input device is paired with. The input device may include sensory feedback indicating the host device actively paired with the input device, and may enable switching between host devices. | 10-24-2013 |
20140267040 | INPUT DEVICE WITH A CUSTOMIZABLE CONTOUR - Certain embodiments of the invention include an input device (e.g., a computer mouse) including a processor, a housing including a top side, the housing configured to support a user's hand, and a detachable cover plate configured to attach to the top side of the housing and support a user's hand. The cover plate can include a shape memory polymer (SMP) disposed thereon, where the SMP is pliable and operable to conform to the user's hand when a temperature of the SMP is at or above a threshold value. Furthermore, the SMP can be firm and non-conforming when the temperature of the SMP falls below the threshold value. A heating unit controlled by the processor can be configured to control the temperature of the shape memory polymer. The detachable cover plate can include the shape memory polymer disposed in areas configured to contact a user's palm and thumb. | 09-18-2014 |
