  • Publication number: 20210224556
    Abstract: In various examples, sensor data representative of an image of a field of view of a vehicle sensor may be received and the sensor data may be applied to a machine learning model. The machine learning model may compute a segmentation mask representative of portions of the image corresponding to lane markings of the driving surface of the vehicle. Analysis of the segmentation mask may be performed to determine lane marking types, and lane boundaries may be generated by performing curve fitting on the lane markings corresponding to each of the lane marking types. The data representative of the lane boundaries may then be sent to a component of the vehicle for use in navigating the vehicle through the driving surface.

  • Publication number: 20190082185
    Abstract: Systems and methods for efficient lossless compression of captured raw image information are presented. A method can comprise: receiving raw image data from an image capture device, segregating the pixel data into a base layer portion and an enhanced layer portion, reconfiguring the base layer portion expressed in the first color space values from a raw capture format into a pseudo second color space compression mechanism compatible format, and compressing the reconfigured base layer portion of first color space values. The raw image data can include pixel data are expressed in first color space values. The segregation can be based upon various factors, including a compression benefits analysis of a boundary location between the base layer portion and enhanced layer portion. The reconfiguring the base layer portion can include separating the base layer portion based upon multiple components within the raw data; and forming base layer video frames from the multiple components.

  • Patent number: 6853381
    Abstract: In accordance with the present invention, a write behind controller receives control information from a display device controller in order to determine a current location available in a frame buffer for receiving information. Write accesses of the frame buffer by a rendering engine are prohibited if the access is to an area below a currently available location of the frame buffer. Generally, the rendering engine will be stalled when the requested address location has not yet displayed its data. Subsequently, the write access to the frame buffer is allowed when location has been rastered.

  • Publication number: 20020079999
    Abstract: A coil assembly includes a cylindrical ferrite core having a top end, a bottom end, an inner opening extending from the top and to the bottom end, a cylindrical outer surface, and a stepped portion formed at the bottom end, where the stepped portion extends past the outer surface of the cylindrical core. A first high dielectric material is located over at least a substantial portion of the surface of the cylindrical core by use of a coating process. A length of conductive wire is wound around the first high dielectric material located over the outer surface of the cylindrical ferrite core. The winding of the wire around the core forms a coil having a first end and a second end. A second high dielectric material is then located over the coil, not including the first end and second ends. A coil holder is formed including a base portion having a base opening formed substantially at a centered area of the coiled holder.

  • Patent number: 5952790
    Abstract: A ballast circuit for a gas discharge lamp comprises a resonant load circuit incorporating the gas discharge lamp and including a resonant inductance and a resonant capacitance. A d.c.-to-a.c. converter circuit induces an a.c. current in the resonant load circuit. The converter circuit comprises first and second switches serially connected between a bus conductor at a d.c. voltage and a reference conductor, and which are connected together at a common node through which the a.c. load current flows. A voltage-breakover (VBO) device is effectively connected between the common node and a second node. A network is provided for setting the voltage of the second node with respect to the common node at less than the breakover voltage of the VBO device when the lamp is operating at steady state. A polarity-determining impedance is connected between the common node and one of the bus conductor and the reference conductor, to set the initial polarity of pulse to be generated upon the firing of the VBO device.

  • Patent number: 5866991
    Abstract: An electrodeless gas discharge lamp includes a vitreous envelope containing a discharge medium. An excitation coil is positioned in relation to the vitreous envelope so as to excite the discharge medium therein. The excitation coil is adapted to be driven by an RF oscillator. The excitation coil has first and second ends and is effective for exciting the discharge medium to emit light with electromagnetic fields that are generated by the excitation coil. The excitation coil includes a first wire wound generally helically from the first end to the second end in a first helical direction to form first winding turns, and further includes a second wire wound generally helically from the first end to the second end in second helical direction opposite to that of the first helical direction to form second winding turns. Preferably, a generally cylindrical former is provided for holding the first and second wires between the first and second ends of the coil.
