摘要： An optical mouse images as an array of pixels the spatial features of generally any micro textured or micro detailed work surface below the mouse. The photo detector responses are digitized and stored as a frame into memory. Motion produces successive frames of translated patterns of pixel information, which are compared by autocorrelation to ascertain the direction and amount of movement. A hold feature suspends the production of movement signals to the computer, allowing the mouse to be physically relocated on the work surface without disturbing the position on the screen of the pointer. This may be needed if the operator runs out of room to physically move the mouse further, but the screen pointer still needs to go further. The hold feature may be implemented with an actual button, a separate proximity detector or by detecting the presence of a characteristic condition in the digitized data, such as loss of correlation or velocity in excess of a selected limit. A convenient place for an actual hold button is along the sides of the mouse near the bottom, where the thumb and the opposing ring finger grip the mouse. The gripping force used to lift the mouse engages the hold function. Hold may incorporate a brief delay upon either the release of the hold button, detection of proper proximity or the return of reasonable digitized values. During that delay any illumination control or AGC servo loops stabilize. A new reference frame is taken prior to the resumption of motion detection.

摘要： A circuit for controlling the energy delivered to a heater resistor of a thermal inkjet printhead. The circuit includes a decoder for receiving an address for the heater resistor in a multiplexed environment. When the heater resistor is addressed, the output of the decoder is level shifted through a pair of inverters and transmitted to the gate of a PMOS driver that delivers the energy to the heater resistor. The PMOS driver responds to the voltage level of the adjacent inverter output in setting the level of the driver output voltage that is applied to the resistor. Feedback circuitry in the form of an analog or digital comparator compares the driver output voltage against a reference voltage. The comparator's output signal is fed back through the level shifter as the inverter output that is applied to the gate of the PMOS driver. The inverter output adjusts the driver output voltage so as to maintain the voltage across the heater resistor at a level that delivers a desired amount of energy to the heater resistor.

摘要： Augmented reality light guide display techniques are described. In one or more implementations, an apparatus includes a housing configured in a hand-held form factor, one or more sensors configured to detect a position and orientation of the housing in three dimensions in a physical environment of the housing, a light guide that is at least partially transparent and supported by the housing, a light engine that is optically coupled to the light guide, and one or more modules disposed within the housing and implemented at least partially in hardware. The one or more modules are configured to calculate a position and orientation of an augmentation and cause the light engine to output the augmentation for display using the light guide such that the augmentation is viewable concurrently with at least a portion of the physical environment through the light guide.

摘要： Multiple pixels within a pixel array share a common output line. Each output line from the array is connected to one or more storage elements. Each of the storage elements receives a counter signal corresponding to levels of a reference voltage within each of the pixels. When an output line signal reaches a predetermined value, a storage element receiving that predetermined value latches the current value of the counter signal. Outputs from pixels of multiple columns in the array may be time-multiplexed onto the output lines or may form a serial scan chain connected to a single output line.

摘要： A CMOS digital integrated circuit (IC) chip on which an image is captured, digitized, and then processed on-chip in substantially the digital domain. A preferred embodiment comprises imaging circuitry including a photo cell array for capturing an image and generating a representative analog signal, conversion circuitry including an n-bit successive approximation register (SAR) analog-to-digital converter for converting the analog signal to a corresponding digital signal, filter circuitry including a spatial filter for edge and contrast enhancement of the corresponding image, compression circuitry for reducing the digital signal storage needs, correlation circuitry for processing the digital signal to generate result surface on which a minima resides representing a best fit image displacement between the captured image and previous images, interpolation circuitry for mapping the result surface into x- and y-coordinates, and an interface with a device using the chip, such as a hand-held scanner. The filter circuitry, the compression circuitry, the correlation circuitry and the interpolation circuitry are all advantageously embodied in an on-chip digital signal processor (DSP). The DSP embodiment allows precise algorithmic processing of the digitized signal with almost infinite hold time, depending on storage capability. The corresponding mathematical computations are thus no longer subject to the vagaries of CMOS chip structure processing analog signals. As a result, precise and accurate navigation enables a predictable, reliable and manufacturable design. Parameters may also be programmed into the DSP's “software,” making the chip tunable, as well as flexible and adaptable for different applications.
