International Classification:

F21V 29/00

US Classification:

362294, 362373, 36224902, 362218, 36221711

Abstract:

Light fixtures including at least an enclosure, a heat sink, and a light-emitting diode. In one embodiment the heat sink has a first portion having fins (that protrudes outside of the enclosure) and a second portion to house and mount the LEDs (that is positioned within the enclosure). Certain embodiments also provide for gaskets and other structure to prevent leakage between the heat sink and the enclosure, such that the light fixture is water-resistant.

Abstract:

Light engines for inclusion in luminaires. Some embodiments of the light engine include a heat sink, a reflector, and light emitting diodes. Some embodiments of the heat sink include perforations. The reflector includes a reflective surface that extends around at least a portion of the light emitting diodes. In some embodiments, a portion of the reflector is sandwiched between the light emitting diodes and the heat sink. In some embodiments, an end of the reflector terminates above the light emitting diodes to reduce the concentration of light directly above the light emitting diodes but rather distribute the light outwardly from the luminaire.

International Classification:

H04W 64/00

US Classification:

4554561

Abstract:

Determining levels of geographic redundancy among radios of a wireless radio network is described. The level of geographic redundancy for a radio can affect the determination of location information for a user equipment (UE) on the wireless radio network. The disclosed subject matter can be employed in conjunction with timed fingerprint location (TFL) technologies to facilitate selection of radios employed in determining time values for TFL location determination. Levels of geographic redundancy can be employed to rank or order radios of a wireless radio network so as to reduce the likelihood of using geographically redundant radios in location determination. Further, rules can be selected to adjust threshold values and equations employed in determining the levels of geographic redundancy. Moreover, rules can be selected to apply boundary conditions to reduce the number of determinations formed for a set of radios of the wireless radio network.

International Classification:

H04M 100

US Classification:

379351

Abstract:

A DTMF digit detecting method and apparatus includes signal state identifier (32) for identifying whether the received signal is in a DTMF-digit-detect state, a no-detect high-energy state, or a no-detect low-energy state, digit candidate identification processor (34) for identifying a digit candidate when the presence of a state other than the no-detect low-energy state is detected following a detection of the presence of the no-detect low-energy state for a first predetermined period of time, digit identifier (32) for identifying a DTMF digit corresponding to a sample group in a DTMF-digit-detect state, and valid digit identifier (34) for identifying a valid DTMF digit when at least a first predetermined number of sample groups are all in the DTMF-digit-detect state or in an allowable combination of states. An allowable combination of states exists provided the following conditions are met: (1) at least half of the first predetermined number of sample groups are in the DTMF-digit-detect state and correspond to the same DTMF digit; (2) no two sequential sample groups are in a state other than the DTMF-digit-detect state; and (3) no two sequential sample groups in the DTMF-digit-detect state correspond to one or more DTMF digits other than the DTMF digit corresponding to at least half of the first predetermined number of sample groups.

Abstract:

Silicone-containing light fixture optics. A method for manufacturing an optical component may include mixing two precursors of silicone, opening a first gate of an optic forming device, moving the silicone mixture from the extrusion machine into the optic forming device, cooling the silicone mixture as it enters the optic forming device, filling a mold within the optic forming device with the silicone mixture, closing the first gate, and heating the silicone mixture in the mold to at least partially cure the silicone. Alternatively, a method for manufacturing an optical component may include depositing a layer of heat cured silicone optical material to an optical structure, arranging one or more at least partially cured silicone optics on the layer of heat cured silicone optical material, and heating the heat cured silicone optical material to permanently adhere the one or more at least partially cured silicone optics to the optical structure.

Abstract:

A luminaire includes a housing, a luminous zone coupled with the housing, and one or more transition zones coupled with the housing and disposed adjacent to the luminous zone. The luminous zone provides a first light to an illuminated area, and the one or more transition zones provide a second light to the illuminated area. The first light is harsher than the second light. A method of illuminating an area includes providing a first light to the area from a luminous zone of a luminaire and providing a second light to the area from one or more transition zones disposed adjacent to the luminous zone within the luminaire. The first light is a harsher light than the second light.
