  • Loudspeaker
    Publication number: 20130333975
    Abstract: The present invention provides a loudspeaker with a port tube having an acoustic leakage path through a motile part thereof. In this way, excess energy caused by longitudinal resonance at higher frequencies is radiated transversely through the port tube walls rather than contributing to the output of the loudspeaker itself.

  • Loudspeaker
    Publication number: 20130277140
    Abstract: A loudspeaker comprises a reflex port located within the enclosure at a point substantially co-incident with a nodal surface of at least one resonant mode within the enclosure. The amplitude of that resonance at the input to the duct is minimised, hence assisting in filtering out the effect of that resonance without needing absorptive material. Ideally, it is placed at the intersection of two or more nodal surfaces.

  • Molded snowshoe with compound deck
    Patent number: 8474158
    Abstract: A molded or plastic composite snowshoe is formed of two assembled sections, in a way that imparts flexibility to the snowshoe, allowing some degree of torsional twisting or warping flexibility so that the snowshoe adapts to uneven terrain. In a principal embodiment the molded snowshoe is divided into forward and aft sections along a line slightly behind the nose area and near the pivot axis in the case of a pitch-pivoting binding. Joints between sections are in narrow rims at left and right, at opposed sides of a large central opening for the crampon/binding and boot. The joints are designed to securely hold the forward and aft molded sections together but to allow a degree of torsion between them when needed. Steel structural traction rails extend across the joints but are constructed and secured to the snowshoe sections in a manner that preserves the desired flexibility.

  • Loudspeaker and diaphragm therefor
    Publication number: 20130070953
    Abstract: A loudspeaker radiating diaphragm can be stiffened to help increase the breakup frequency to above the working frequency range of the driver concerned, by forming it of a moulded part and an attached formed part. The moulded part is a radiating surface with stiffening ribs. The formed part is a thin surface of high modulus material, attached to the rear of the ribs. The overall structure can have significantly higher stiffness than either of the two parts. This helps in designing a loudspeaker driver that does not breakup within its working frequency range.

  • Power switching for electronic device test equipment
    Patent number: 8401543
    Abstract: An apparatus, system and method are provided for testing a battery-powered electronic device-under-test in a transport frame engaged with a test fixture. A transport frame power supply is arranged to provide power to the DUT in a pre-testing stage. A switching circuit is arranged to switch from the transport frame power supply to a test fixture power supply in response to receiving a power switching signal indicating satisfaction of a pre-testing condition. Power from the test fixture power supply can then be switched back to the first transport frame, or to a second transport frame, to begin testing a second DUT. The ability to start a DUT test without having to wait for the DUT to boot-up in the test fixture reduces test time and increases efficiency of use of test equipment.

  • Snowshoe with flexible tail
    Patent number: 8171658
    Abstract: A snowshoe of molded plastic material has a tail section with greater flexibility than the main body section, thereby allowing the tail to give and deform as the snowshoe tail is engaged against the terrain during the gait of the user. At the same time, the tail is stiff enough to provide flotation needed when the full weight of the user is on one snowshoe fully engaged against terrain, such as soft snow.

  • Primitive program compilation for flat attributes with provoking vertex independence
    Patent number: 8171461
    Abstract: Systems and methods for compiling high-level primitive programs are used to generate primitive program micro-code for execution by a primitive processor. A compiler is configured to produce micro-code for a specific target primitive processor based on the target primitive processor's capabilities. The compiler supports features of the high-level primitive program by providing conversions for different applications programming interface conventions, determining output primitive types, initializing attribute arrays based on primitive input profile modifiers, and determining vertex set lengths from specified primitive input types.

    Abstract: A roadside equipment (RSE) system that can be used for controlling traffic signals and other equipment and corresponding method. A method includes maintaining a traffic signal in a GREEN phase in a first direction, including displaying a GREEN indicator in the first direction. The method includes detecting an event indicating that the phase of the traffic signal in the first direction should be changed and changing the phase of the traffic signal to a pre-YELLOW phase in response to the detected event, including continuing to display the GREEN indicator in the first direction. The method includes wirelessly transmitting a message indicating the pre-YELLOW phase and a phase time, the phase time indicating a next change of phase of the traffic signal, and changing the phase of the traffic signal to a YELLOW phase when the phase time has been reached.
