  • Patent number: 8334924
    Abstract: A device that analyzes an image. The device includes a circuit that receives an image that includes a plurality of pixels. The circuit creates a histogram of the image and analyzes the histogram to determine an acceptable exposure of the image. The histogram may include a plurality of bins versus a population of pixels associated with each bin. By way of example, the bins may be associated with an intensity of light. The images and histograms may include data defined by low dynamic range number of bits and/or an extended dynamic range number of bits. Certain features and criteria of the image may be determined and analyzed to determine whether the image has an acceptable exposure. If the image is unacceptable, an exposure characteristic can be changed and the process can be repeated until an acceptable image is obtained.

  • Patent number: 8319433
    Abstract: An LED-based lighting unit for retrofitting a fluorescent light fixture in a transit vehicle has a concave frame or structure conforming to the shape of the fluorescent lighting fixture cavity, connector pins on either end of the frame for secure attachment to sockets of the fluorescent fixture, a plurality of LED modules for illuminating an area of a transit vehicle, a power adapter for receiving and converting an input power supply signal, and a diffusive lens cover. The frame may have rear fins or other features for facilitating dissipation of heat generated by the LEDs. A controller adjusts the intensity of the LEDs based on a reading from a temperature sensor and on a manual brightness setting. The change in light output may be accomplished by reducing a duty cycle of a pulse width modulated (PWM) waveform supplying the LEDs.

  • Patent number: 8297552
    Abstract: A mobile helicopter landing pad comprises a platform with one or more elongate, concave guiding channels for aligning a helicopter on the landing pad by forcing the helicopter's skates into a specific alignment upon landing. The guiding channels may have laterally disposed rollers or else be made of slick material to allow the helicopter to slide towards the base of the guiding channel under the helicopter's own weight. Additional crosswise rollers at the bottom of the guiding channel(s) may be provided to allow the helicopter to be moved forward or backward after landing. A blade locking arm swings upward and secures the top rotor. The pad may include a foldable enclosure that protects the helicopter after landing, and an electronic guidance system that assists the pilot during landing by providing instructions to the pilot or visual indications of the prevailing wind direction and velocity, through illuminated signals on the platform.

  • Patent number: 8264591
    Abstract: An auto focus image system that includes an image sensor coupled to a controller. The image sensor captures an image that has at least one edge with a width. The controller generates a focus signal that is a function of the edge width. A lens receives the focus signal and adjust a focus. The edge width can be determined by various techniques including the use of gradients. A histogram of edge widths can be used to determine whether a particular image is focused or unfocused. A histogram with a large population of thin edge widths is indicative of a focused image.

  • Patent number: 8174593
    Abstract: A method for determining whether a image pixel of an image comprising a plurality of image pixels generated from a pixel array of an image sensor, each having an image pixel value formed from a respective reset level, has suffered a darkening resulting from a drop in its reset level prior to sampling due to a high intensity illumination. Where a first image pixel has its reset level detected to have crossed a threshold and a second image pixel is saturated, a third image pixel between the first and second image pixels is determined to have suffered such darkening if it is not saturated and if no intervening image pixel between the first and the third image pixels either is saturated or is generated from a reset level detected to have crossed a threshold. The crossing of the reset level may be signaled by a reserved codeword.

  • Patent number: 8143143
    Abstract: A process is provided for etching a silicon-containing substrate to form nanowire arrays. In this process, one deposits nanoparticles and a metal film onto the substrate in such a way that the metal is present and touches silicon where etching is desired and is blocked from touching silicon or not present elsewhere. One submerges the metallized substrate into an etchant aqueous solution comprising HF and an oxidizing agent. In this way arrays of nanowires with controlled diameter and length are produced.

  • Patent number: 8145995
    Abstract: Mobile devices enabled to support resolution-independent scalable display of Internet (Web) content to allow Web pages to be scaled (zoomed) and panned for better viewing on smaller screen sizes. The mobile devices employ software-based processing of original Web content, including HTML-based content, XML, cascade style sheets, etc. to enable Web page content to be rapidly rendered, zoomed, and panned. Moreover, the rendered displays provide substantially the same or identical layout as the original Web page, enabling users to easily navigate to selected content and features on literally Billions of Web pages. User input schemes include tap-based context zooming that enables users to selectively zoom in on objects including columns, images, and paragraphs by simply tapping on them. Display lists may also be employed to provide further enhancements in rendering speed. Additionally, hardware-based programmed logic may be employed to facilitate various operations.

  • Patent number: 8138837
    Abstract: A dynamic power supply for N amplifiers includes first and second power boost circuits which temporarily boost the positive or negative power supply rail, respectively. A control circuit monitors amplifier output signal levels and provides power boost control signals to the power boost circuits, which temporarily raise the positive supply voltage above the nominal voltage level in tandem with the highest output signal from the N amplifiers and lower the negative supply voltage below the nominal voltage level in tandem with the lowest output signal level from the N amplifiers. The power boost circuits each may be coupled to a reservoir capacitor from which current is drawn to provide the power boost. When inactive, the reservoir capacitors charge up from the respective power supply rails. The dynamic power supply is well suited for audio amplification systems.

  • Patent number: 8135158
    Abstract: A sound reproduction system includes one or more arrays of drive units, coupled with sound processing allowing improved steerability, directional control, width control, and/or beam overlay. A speaker column may comprise two arrays facing one another, the drive units being perpendicular to the speaker unit front, with the acoustic output of each line array being compressed, turned and output from an elongate slot. The drive units may be staggered with respect to those in the opposing array. The arrays may be arc-shaped else straight. Selective delays to simulate an arced pattern. Differential delays applied to the drive units in a sub-array allow beam steering. Additional drive units, such as high frequency drivers, may be added along the length of the elongate slot or elsewhere to increase the dynamic frequency range of the speaker system. A collocated sound processor and amplifier output stage may be integrated with the speaker unit.

  • Patent number: 8049153
    Abstract: An image sensor pixel that includes a photoelectric conversion unit supported by a substrate and an insulator adjacent to the substrate. The pixel includes a light guide that is located within an opening of the insulator and extends above the insulator such that a portion of the light guide has an air interface. The air interface improves the internal reflection of the light guide. Additionally, the light guide and an adjacent color filter are constructed with a process that optimizes the upper aperture of the light guide. These characteristics of the light guide eliminate the need for a microlens.
