  • Patent number: 7233313
    Abstract: The present invention provides a control knob on a device that allows a user to control functions of the device. In one embodiment, the knob is rotatable in a rotary degree of freedom and moveable in at least one transverse direction approximately perpendicular to the axis. An actuator is coupled to the knob to output a force in the rotary degree of freedom about the axis, thus providing force feedback. In a different embodiment, the knob is provided with force feedback in a rotary degree of freedom about an axis and is also moveable in a linear degree of freedom approximately parallel to the axis, allowing the knob to be pushed and/or pulled by the user. The device controlled by the knob can be a variety of types of devices, such as an audio device, video device, etc. The device can also include a display providing an image updated in response to manipulation of the knob.

  • Patent number: 7079127
    Abstract: A reference voltage generation circuit outputs multi-valued reference voltages by a ladder resistance circuit connected between a first power supply line to which a power supply voltage on the high potential side is supplied and a second power supply line to which a power supply voltage on the low potential side is supplied. The ladder resistance circuit is formed by connecting a plurality of resistance circuits in series. A first impedance variable circuit of the reference voltage generation circuit changes a first impedance value (resistance value) between the first power supply line and a jth (j is an integer) divided node. A second impedance variable circuit in the reference voltage generation circuit changes a second impedance value (resistance value) between the kth (1?j<k?i, k is an integer) divided node and the second power supply line.

  • Patent number: 7046221
    Abstract: A display system includes a display panel having an array of pixels, the pixels having ON states and OFF states. The pixels form images by modulating light in a temporal sequence during an image frame in response to drive signals generated from incoming video data. A light source arrangement that emits at least two colors of light illuminates the display panel. The image frame is divided into color segments with only one color of light being emitted from the light source during each segment. The color segments are further divided into grayscale periods. Transition segments are provided for the transitions between colors. The state of each pixel during these transition segments is a function of the desired brightness level for each pixel, as derived from incoming video data.

Another embodiment provides an actuator that includes a shaft that is coaxial with the axis of rotation and which can be moved linearly along the axis of rotation with respect to actuator housing to accommodate linear motion of the knob. In another embodiment, a gear assembly including two interlocked gears is provided to transmit rotational motion from the knob to the sensor, and the interlocked gears translate with respect to each other when the knob is translated along the rotational axis.

  • Patent number: 6982695
    Abstract: The invention provides a method for software contrast control and a portable computer implementing software contrast control. The contrast control is initiated by a single interaction with an input mechanism, for example a pressing of a dedicated contrast control button. The method can be applied more generally to viewing parameters other than contrast such as brightness, color bit depth, color versus monochrome, and screen resolution. The method includes a processor disposed in the portable computer receiving an activation signal from a button or other input mechanism, and displaying viewing parameter adjustment graphics on the image screen. The method continues with the processor receiving a viewing parameter adjustment signal and responding to the adjustment signal by adjusting the viewing parameter levels for the image screen to levels based on the adjustment graphics.
