    Abstract: Subdividing a color space is described for vector error diffusion which includes obtaining color coordinates for each primary color in the color space, and comparing the color coordinates to a threshold value for each coordinate plane of the color space. In response to the comparing, each primary color is grouped into a quadrant of the color space, wherein each quadrant is defined by the threshold value for each coordinate plane. In other aspects, a mapping a color to a closet primary color is described in a color space that includes a display determining color coordinates of the color and identifying a matching quadrant of a plurality of quadrants dividing the color space, wherein the determined color coordinates fall within the matching quadrant. A representative display device searches for the closest primary color within the matching quadrant and maps the color to the closest primary color found.

    Abstract: The various embodiments include a near-eye display having a transmissive display and a diffractive micro-lens array. The transmissive display may be positioned relative to the diffractive micro-lens array so that the distance between the transmissive display and the diffractive micro-lens array is be approximately equal to focal length of the diffractive micro-lens array. The transmissive display may also be positioned relative to the diffractive micro-lens array so that a percentage of light emitted from the transmissive display is diffracted by the micro-lens array and collimated into focus on a retina of a human eye. The transmissive display may be further positioned relative to the diffractive micro-lens array so that light from a real world scene passes through transparent portions of the transmissive display and is diffracted by the micro-lens array out of focus of the human eye.

    Abstract: Low power wireless communication techniques may be employed in devices that communicate via a wireless body area network, a wireless personal area network, or some other type of wireless communication link. In some implementations the devices may communicate via one or more impulse-based ultra-wideband channels. Inter-pulse duty cycling may be employed to reduce the power consumption of a device. Power may be provided for the transmissions and receptions of pulses by charging and discharging a capacitive element according to the inter-pulse duty cycling. Sub-packet data may be transmitted and received via a common frequency band. A cell phone may multicast to two or more peripherals via wireless communication links.

    Abstract: Power consumption of an output stage such as a class-D output stage may depend on the amplitude and the activity of the signal being output. Here, control signals may be generated to independently control coupled switches of the output stage and to provide a tri-state control scheme for the output stage. These control signals may be generated based on durations of different levels of an input signal over one or more periods of time.

    Abstract: A multiple access technique for a wireless communication system establishes separate channels by defining different time intervals for different channels. In a transmitted reference system different delay periods may be defined between transmitted reference pulses and associated data pulses for different channels. In addition, a multiple access technique may employ a common reference pulse for multiple channels in a transmitted reference system. Another multiple access technique assigns different pulse repetition periods to different channels. One or more of these techniques may be employed in an ultra-wide band system.

    Abstract: Processing may be performed by a first device on behalf of a second device to offload processing from the second device. In some aspects a device from which processing has been offloaded may be advantageously adapted to consume less power, have a smaller size, and have less complexity. Offloaded processing may be employed to enable a first device to process data for transmission and then send the data to another device for processing. Offloaded processing may be employed to enable a first device to process data on behalf of a second device and then send the processed data to the second device. In some aspects the data may be waveform encoded for wireless transmission between the devices. Offloaded processing may be implemented in a static manner or in a dynamic manner.
