Abstract: A light directing apparatus includes an optical substrate having first and second sides, a compound lens outer surface (CLOS) on a first portion of the first side, and first and second protrusions on a second portion of the first side. The CLOS is in optical communication with the second side, the CLOS having mirror image symmetry about a medial plane that contains a centerline of the CLOS. The first protrusion is disposed proximate the CLOS, and in optical communication with the second side. The second protrusion is disposed proximate the first protrusion, and in optical communication with the second side. The first protrusion is disposed between the second protrusion and the CLOS. The first and second protrusions each have a curved apex such that first and second planar section cuts through the optical substrate perpendicular to the medial plane cut twice through each curved apex.

Abstract: A low profile luminaire to be carried by a lighting fixture. The luminaire may include a light source that comprises light-emitting diodes (LEDs), a heat sink thermally coupled to and disposed diametrically outboard of the light source, a reflector in optical communication with and disposed diametrically inboard of the light source, and a light guide in optical communication with at least one of the light source and the reflector and disposed therebetween. Light emitted from the light source may be reflected by the reflector into an edge of the light guide. Light propagating through the light guide may be projected into the environment at a uniform luminance. The luminaire may be dimensioned to cover a nominally sized four-inch can light fixture and/or electrical junction box. A method aspect of the invention details steps for assembling the low profile luminaire with light guide.

Abstract: A method and device generates probability-based recommendations for a fantasy sports game. The method includes receiving first and second rosters for a first and second user, respectively; receiving parameter values for each sport player on the rosters; determining a score value for the sport players based on the parameter values; determining first and second lineups for the first and second users, respectively, the first lineup having a first projected probability distribution and the second lineup having a second projected probability distribution, the first and second projected probability distributions determined as a function of the score values; and determining a win probability value based on the first and second projected probability distributions, the win probability value indicative of a prediction of a comparison between a first actual total score value and a second actual total score value.

Abstract: A luminaire with a prismatic optic permits the nearly uniform distribution of light about the luminaire. The prismatic optic permits the use of directional light sources, such as light emitting diodes, while maintaining the uniform light distribution. Furthermore, a concave shape of the optic further enables uniform light distribution. When light emitting diodes are used, the luminaire further includes a heat sink to maintain a desirable operational temperature without negatively affecting the light distribution properties of the luminaire.

Abstract: A luminaire provides light having a distribution pattern with high center beam candle power and a gradual gradient across a wide area. The luminaire includes a light source having first and second sets of light emitting elements selected and positioned to achieve the desired light distribution pattern. The luminaire further includes an optic configured to refract light emitted from the light source to achieve the desired light distribution pattern.

Abstract: A reflector system for a lighting device. The system uses two reflective surfaces to redirect the light before it is emitted. The light source/sources are disposed at the base of a secondary reflector. The first reflective surface is provided by a primary reflector which is arranged proximate to the source/sources. The primary reflector initially redirects, and in some cases diffuses, light from the sources such that the different wavelengths of light are mixed as they are redirected toward the secondary reflector. The secondary reflector functions primarily to shape the light into a desired output beam. The primary and secondary reflectors may be specular or diffuse and may comprise faceted surfaces. The reflector arrangement allows the source to be placed at the base of the secondary reflector where it may be thermally coupled to a housing or another structure to provide an outlet for heat generated by the sources.

Abstract: A removable pedal positioner to engage a crank arm and a pedal of a bicycle to position the pedal in a generally horizontal position. One embodiment comprises a bridge, at least one prong, and a mounting post. The mounting post engages the crank arm while the at least one prong extends past the crank arm to position the pedal in a generally horizontal position. In other embodiments, the positioner utilizes a flexible clamp to secure the positioner to the crank arm thereby positioning the pedal in a generally horizontal position.

Abstract: A mounting pedestal is designed to hold a DUT in position for both electrical testing and vibration testing. The design is such that the pedestal can remain thermally sealed from an environment created within a confined area so as to impart vibration to a DUT positioned within the environmentally protected area, the vibration coming from a vibrator outside the environmentally sealed area. The pedestal, in one embodiment, extends through the base of a DUT holding tray while still preserving the environment within the sealed area. In one embodiment, the pedestal can position the DUT in any of several selected orientations.

Abstract: The problems inherent with connecting a DUT to a test station have been solved by the use of a tray designed to allow a wide variety of different DUTs to be physically connected individually to a test station using a universal test station connector. The tray allows for the association therewith of a personality module which serves to provide the proper physical connections and to electrically condition the test station to the electrical characteristics of the DUT. The tray allows for sealed environmental testing of the DUT without impacting any physical connections between the DUT and the test station. The tray also allows for the DUT to be vibrated from externally applied motion without interfering with either the sealed environment around the DUT and without imparting motion to the physical connection between the DUT and the test station.

Abstract: A two-part connector can be achieved for high performance situations using blind-mate insertion by using power activation. In one embodiment, the male and female portions of a standard RF connector can be securely mated so as to achieve high performance without the need for a screw type locking mechanism. Power activation is achieved, in one embodiment, by pneumatic actuation of a piston having fingers which engage an outer edge of a housing formed around the female portion of the connector so as to pull the female portion into a tight mating relationship with the male portion.

Abstract: The present invention is directed to a system and method to seal a device under test (DUT) into a portable chamber wherein the magnitude of the temperature, either up or down, is maintained by continuously providing a control signal applied to heating or cooling elements. In one embodiment, voltage polarity is used to select between heat and cold and voltage magnitude is used to control temperature. In one embodiment, several parameters within the chamber are monitored and the resultant signals are then used to define the magnitude and polarity of the control voltage. In one embodiment, a controller is used to receive information pertaining to the DUT. This information, for example, includes the identity of the DUT as well as its stabilization time and set temperature. The set temperature may be adjusted according to historical data pertaining to the DUT to compensate for differences over other test methods.
