Abstract: Aspects of the present disclosure provide a system for abating a hydrocarbon compound (HCC) in air using photocatalytic oxidation (PCO). For example, the system can include an air handling unit (AHU), a sensor and a control panel. The AHU can be configured to abate HCC in air using PCO. The sensor can be configured to sense a level of the HCC in the air. The control panel can be configured to control the AHU based on the level of the HCC.

Abstract: A Volatile Organic Compound (VOC) mitigation system employs a combination of technologies coupling VOC laden exhaust with a reciprocating engine and generator system (Combined Heat & Power (CHP) System) with heat recovery to destroy the VOC emissions and generate electric power and useful thermal energy.

Abstract: An LED unit (20) having increased light output. The LED unit (20) includes a submount substrate (22) having a cavity (24). An LED chip (30) is electrically mounted within the cavity (24) and a phosphor layer (34) is deposited in the cavity (24) that converts blue light from the LED chip (30) into white light suitable for a vehicle headlight (10). The walls of the cavity (24) are metalized (40) to increase the light output intensity. In one embodiment, a clear protective layer (46) is deposited in the cavity (24) over the phosphor layer (34).

Abstract: A vehicle headlight (12) that employs a plurality of LED units (38) that emit white light. Each LED unit (38) employs chip-on-board technology where LED semiconductor chips (64) are mounted directly to a submount substrate (56) using solder or stud bumps (60). An elongated lens (28) is molded over the LED unit (38) in contact with a base substrate (48). Light emitted from the semiconductor chip (64) is reflected and directed by the lens (28) to generate a beam of light (58). Some of the light emitted from the LED semiconductor chip (64) is redirected back to the submount substrate (56) to be reflected back into the lens (28) to increase the light intensity of the LED unit (38). Several of the elongated lens (28) and associated LED units (38) are optically glued to a single prism (24) that collects all of the light beams from all of the LED units (38).

Abstract: An LED headlamp assembly (10) for a vehicle. The headlamp assembly (10) includes a plurality of LED units (14) mounted to a common carrier (16), where the LED units (14) include one or more LEDs and generate white light. The headlamp assembly (10) further includes a headlamp housing (28) that is mounted to the vehicle by a mounting frame (52). The carrier (16) is sealed to the housing (28) by a flexible bellows (34). An outer lens (26) is mounted to the housing (28) so that the LED units (14) are positioned within a sealed compartment (42). A backside of the carrier (16) outside of the sealed compartment (42) includes fins (46) or other heat sinking devices to remove heat generated by the LED units (14). The frame (52) allows convective air to flow around the heat sink (46) to remove heat from the LED units (14).

Abstract: A center high mounted stop lamp (12) including a plurality of LEDs (34) mounted on a printed circuit board (30). TIR lenses (40) are employed to focus the light from the LEDs (34) to give an even lighting appearance. The TIR lenses (40) include a prism (44) for directing the light in a desired direction. The circuit board (30) and lenses (40) are mounted in a housing (18) so that each LED (34) includes a separate lens (40) configured relative thereto to provide the desired collection and reflectance of the light. The housing (18) includes a plurality of posts (70) that extend through openings (48, 50) in the circuit board (30) and the lenses (40) to align the LEDs (34) to the lenses (40) relative to the housing (18).

Abstract: RF energy radiated by impacting munition rounds is used to provide an indication to a gunner where the rounds from his gun are striking, or to control a gun servo (158) to automatically correct the aiming of the gun. The RF energy from the rounds is received by several antennas (32, 34, 36) in a known geometry and the angle of arrival computed from the differences in the times of arrival at each antenna. The impact locations can be displayed in the existing gun sight, or in a head up display for the gunner. The angle of arrival information can further be used to control a gun aiming servo (158) to correct the aim of the gun to improve accuracy.
