  • Patent number: 8633893
    Abstract: A solid-state roller on a pointing device with enhanced features. The solid-state design described herein allows the sensor to be placed on any shape of surface, such as one that has curvature in two directions. In one embodiment, a trench or downward curve contains sensors for detecting finger movement. The user's finger can thus bend about a knuckle in a curved motion to activate the sensor, requiring little or no movement of the finger up and down. The solid-state sensors can be of one of a number of designs. In one embodiment, multiple electrodes are contacted by a finger as it moves. Each electrode is coupled to a capacitive detection circuit, for detecting the change in capacitance as the electrode is contacted by the finger.

  • Patent number: 7916120
    Abstract: An input device having a housing; a pointing device coupled with the housing having a plurality of buttons; a scrolling element coupled with the housing; and a module for detecting user input for operating the input device in at least a first mode and a second mode, where in the first mode, the input device operates as a tabletop computer pointing device, and where in the second mode, the input device operates as a hand-held presentation device used to control a computer-based presentation.

  • Patent number: 6879316
    Abstract: An input device with a pressure-sensitive element using a pressure sensing resistor. A solid elastomeric material is mounted over the pressure sensing resistor to transfer a force from the user's finger to the pressure sensitive resistor without visible deformation of the elastomeric material. This provides a comfortable button for a user which does not require the compression of a domed cap to provide pressure-sensing input. In another aspect of the invention, a pressure-sensing input element utilizes both the amount of pressure and the amount of time to determine the type of signal provided to the electronic system. In another aspect of the present invention, an input device contains a first scrolling element (e.g. a wheel) and includes a switch button mounted close to the scrolling element to activate continuous scrolling.

  • Patent number: 6859196
    Abstract: An input device having a housing and electronic circuitry for detecting user inputs, and transmitting signals corresponding to those inputs to an electronic device, such as a computer. A sleep mode is provided for the electronic circuitry to conserve power. A hand detection circuit is provided for detecting the proximity of a user's hand to the housing and producing a hand detect signal in response. The hand detect signal will awaken the input device from its sleep mode.

  • Publication number: 20020126094
    Abstract: An input device having a housing and electronic circuitry for detecting user inputs, and transmitting signals corresponding to those inputs to an electronic device, such as a computer. An antenna is provided for transmitting or receiving signals. A hand detection circuit is provided, which uses said antenna for detecting the proximity of a user's hand to the housing and producing a hand detect signal in response. In one embodiment, the antenna is a capacitive antenna. A capacitor is switched in parallel with the antenna when it is used in antenna mode, so that the impact on the antenna signaling of the capacitance of a user's hand is minimized. In one embodiment, a sleep mode is provided for the electronic circuitry to conserve power. The hand detect signal will awaken the input device from its sleep mode.
