| 20110194722 | METHOD AND APPARATUS FOR A LOUDSPEAKER ASSEMBLY - The present invention relates to a loudspeaker assembly and a method of assembling a loudspeaker assembly. In one or more embodiments, the invention comprises forming a front baffle from a first material, the front baffle comprising a first driver mounting portion, an intermediate portion, and an edge mounting portion. A first driver aperture is formed in the first driver mounting portion, and a port aperture is formed in the intermediate portion. A first driver is installed in the first driver mounting portion by mounting the first driver proximate to the first driver aperture. A rear baffle is formed from a second material, which, in one or more embodiments, is less stiff than the first material from which the front baffle is formed. The rear baffle comprises a top portion, sidewalls, a recessed mounting portion, and an edge portion. The edge mounting portion of the front baffle is attached to the recessed mounting portion of the rear baffle. In one or more embodiments, the rear baffle is secured to the back of the first driver, such that the driver acts as a structural member that increases the rigidity of the loudspeaker assembly. In one or more embodiments, a back box is placed over the rear baffle. In one or more embodiments, the back box provides thermal insulation. In one or more embodiments, the back box complies with fire protection requirements, such as fire codes. In one or more embodiments, an electrical assembly is installed in the loudspeaker assembly, for example in an electrical compartment formed in the rear baffle. In one or more embodiments, a mounting plate is provided for securely attaching the first driver to a structural support thereby securely attaching the entire loudspeaker assembly to the structural support. One or more apertures are formed in the rear baffle and in the back box to allow the mounting plate to attach to the first driver via a fastener that passes though the rear baffle and the back box. In one or more embodiments, a perforated grille is crimped to the edge portion of the rear baffle and an edge portion of the back box. | 08-11-2011 |

| 20090139800 | TRANSMISSION PUMP SYSTEM - A pump system for use in a transmission includes a first pump, a second pump, and a sump. A first fluid passage connects an inlet of the first pump to a sump filter connected to the sump. A second fluid passage connects an inlet of the second pump to the sump filter of the sump. A third fluid passage connects the inlet of the first pump with the inlet of the second pump. A bypass outlet is in communication with the third fluid passage. | 06-04-2009 |
| 20090142208 | MOTOR AND PUMP ASSEMBLY HAVING IMPROVED SEALING CHARACTERISTICS - The present invention comprehends a gerotor or gear pump driven by a permanent magnet motor which exhibits cogging torque, i.e., resistance to rotation when de-energized caused by interaction between permanent magnets in the rotor and teeth on the stator. Such interaction causes the rotor to come to rest in one of many defined rotational positions and resist rotation when electrical power to the motor has been terminated. The permanent magnet motor is coupled, preferably directly, to a gerotor pump having meshing rotors or a gear pump having meshing gears. When the motor is de-energized, the pump rotors or gears come to rest and their rotation is resisted by the cogging torque of the motor. The invention finds particular application in automotive transmissions and systems with parallel pumps. | 06-04-2009 |
| 20110084015 | SUMP FILTER RESTRAINING DEVICE - A sump filter assembly for filtering hydraulic fluid supplied by a transmission sump includes a filter housing, a support member, a retainer member, and a biasing member. The filter housing has a top surface and a bottom surface, wherein the bottom surface opposes a bottom surface of the transmission sump. The support member includes a first end portion attached to the filter housing. The retainer member is slideably connected to the support member and includes a first end portion having a retaining surface, wherein the retaining surface opposes the top surface of the filter housing. The biasing member has a first end in contact with the retaining surface of the retainer member and a second end in contact with the top surface of the filter housing. | 04-14-2011 |
| 20110146820 | TRANSMISSION HYDRAULIC CONTROL SYSTEM HAVING AN ACCUMULATOR BYPASS VALVE ASSEMBLY - A system for providing pressurized hydraulic fluid includes a pump. A bypass valve assembly includes an inlet port in communication with the pump and an outlet port in communication with an accumulator. The pump and the accumulator are both in communication with a hydraulic control system that controls, lubricates, and cools a transmission of a motor vehicle. The bypass valve assembly has a valve moveable between at least a two positions. The bypass valve assembly is operable to bypass the accumulator when the vehicle is first started such that the pump charges the hydraulic control system before charging the accumulator. The accumulator provides pressurized hydraulic fluid to the hydraulic control system after vehicle start. | 06-23-2011 |

| 20080230900 | DETERMINING THE PLACEMENT OF SEMICONDUCTOR COMPONENTS ON AN INTEGRATED CIRCUIT - Systems and methods are disclosed herein for determining the placement of a standard cell, representing a semiconductor component in a design stage, on an integrated circuit die. One embodiment of a method, among others, comprises analyzing regions of a semiconductor die with respect to the susceptibility of the region to be exposed to radiation. This method further comprises placing the standard cell in one of the analyzed regions of the semiconductor die, the standard cell being placed based on the sensitivity of the standard cell to radiation. The method may also comprise running an algorithm, e.g. using a component placement engine, for determining the placement of semiconductor components on an integrated circuit die. | 09-25-2008 |
