摘要： A lamp having a candle-like appearance and using one or more light-emitting diodes (LEDs) as its light source is presented. The candle-like appearance arises because light is emitted from only a small volume at or near the center of the bulb. The heat sink and control electronics are located outside the bulb of the lamp. Inside the bulb is a set of secondary optics that guide the light from one or more LEDs to an emission point at a prescribed location in the interior of the bulb. The secondary optics include a light pipe that guides light away from the LED chip, and a volume scattering element that receives the light from the light pipe and scatters it into various directions. The volume scattering element is made from a transparent base material, and includes transparent particles of a predetermined size and refractive index. Because the lamp is typically used in an overhead position, such as in a hanging chandelier, the density of particles in the volume scattering element, the particle size and the particle refractive index are chosen to produce a scattering pattern that directs more light downward (toward the base of the bulb) than upward, while maintaining a reasonable efficiency (fraction of produced light that successfully exits the lamp). Simulation results are presented.

摘要： A chain of boundary scan registers is configured to use a two-phase clock signal to avoid data timing race conditions. The two-phase clock signal is generated according to a two-phase clock generator, which includes two self-timed clock pulse generators for each boundary scan register. The two-phase clock generator locally generates a self-timed clock pulse at the rising edge of a clock signal, which triggers a first stage of the boundary scan register. The two-phase clock generator also generates a self-timed clock pulse at the falling edge of the input clock signal, which triggers a second stage of the boundary scan register. The two-phase clock controlled boundary scan register includes two latches, each latch is triggered by one of the self-timed clock pulse generated locally from the rising and falling edge of the input clock signal.

摘要： Methods, systems and apparatuses pertaining to pertaining to precise localization and vehicle-to-everything (V2X) communication for autonomous driving vehicles are described. A processor associated with a vehicle wirelessly obtains a respective location of each of one or more traffic control devices. Each of the one or more traffic control devices is installed near or next to a road, an intersection or an area open to vehicular traffic. The processor then determines a location of the vehicle based at least in part on the respective location of each of one or more traffic control devices.
