  • Publication number: 20200034507
    Abstract: A putative circuit design is represented as a set of movable blocks of predetermined size which must fit into a bounding box, with a plurality of subsets to be interconnected by wires. A total weighted wire length is determined as a function of coordinates of centers of the movable blocks by summing a half perimeter wire length over the plurality of subsets, and a density penalty is determined as a convolution of an indicator function of the current placement and a convolution kernel, via incremental integer computation without use of floating point arithmetic. Blocks are moved to minimize a penalty function which is the sum of the total weighted wire length and the product of a density penalty weight and the density penalty. The process repeats until a maximum value of the density penalty weight is reached or the density penalty approaches zero.

  • Publication number: 20190241931
    Abstract: The present disclosure relates to an assay that measures the level of factor Xa inhibitors in a sample by detecting residual factor Xa activity. In particular, the assay utilizes a mutant variant of prothrombin that lacks proteolytic activity; a prothrombinase complex mixture; and a thrombin-specific inhibitor and measures the factor Xa activity.

  • Patent number: 8632203
    Abstract: A light producing device, such as a flashlight, may have a clip that is removably attached to a body thereof. The clip may comprise a split ring that substantially encircles the body and has a split therein and may also comprise an elongated portion having a proximal end and a distal end. The elongated portion may be attached to the split ring substantially opposite the split. The clip may be readily removed from the body, such as to better facilitate hand holding of the light producing device, to facilitate maintenance or repair of the light producing device, and/or for storage/transportation of the light producing device.

  • Patent number: 8148912
    Abstract: Various lighting devices and related methods of operation are provided which may be used to adjust brightness levels of a plurality of light sources in a staggered fashion in response to a single user control. In one example, a lighting device includes a plurality of light sources. Each light source is adapted to exhibit an associated current brightness level within a range of brightness levels associated with each light source extending from an associated minimum brightness level to an associated maximum brightness level. The lighting device also includes a user control adapted to selectively adjust the current brightness levels exhibited by the light sources in a staggered fashion such that the light sources exhibit different current brightness levels from each other over at least a range of positions of the user control.

  • Patent number: 8096674
    Abstract: Various techniques are provided for implementing a lighting device with selectable output level switching. In one example, a lighting device includes a light source, a controller adapted to provide one or more signals to control the operation of the light source, a power terminal adapted to receive a power source, and a tailcap assembly. The tailcap assembly includes a tailcap, a push button, and a washer disposed in the tailcap. The washer includes at least one arm adapted to be pushed against a surface to selectively connect the controller to the power terminal in response to a manipulation of the tailcap assembly.

  • Patent number: 7926218
    Abstract: Laser aiming apparatus for accurately and conveniently applying elevation and windage adjustments to a laser beam emanating therefrom. A preferred embodiment includes a housing, which may be adapted to be mounted to a gun; a laser module in the housing and including a sleeve having a laser mounted in the sleeve for emitting a laser beam through a front end thereof along the sleeve's longitudinal axis, the sleeve being pivotally mounted in the housing about a first pivot point on the longitudinal axes of the sleeve and the housing; a rocker pivotally mounted in the housing about a second pivot point on the housing's longitudinal axis and spaced from the first pivot point, the rocker coupled to the sleeve for pivoting the sleeve about the first pivot point; and an adjustment apparatus carried by the housing and engaging the rocker for pivotally adjusting position of the rocker about the second pivot point.
