20100091670 | METHOD AND APPARATUS TO ALLOW COEIXTENCE BETWEEN WIRELESS DEVICES - The present invention relates generally to wireless transceivers, and more particularly but not exclusively to non 802.11 detection and avoidance methodologies for wireless devices including transceivers. In one or more implementations, a method for detecting non 802.11 operating in the unlicensed 5.25-5.35 and 5.47-10.725 GHz radio bands, using wireless devices, such as AP, are provided. An AP is used to automatically detect the presence of non 802.11 on all channels in these bands, alert all of its clients, and move to another channel that is known to be devoid of non 802.11 using one or more implementations. | 04-15-2010 |
20110182192 | METHOD AND APPARATUS FOR CALIBRATION OF AN IMPLICIT BEAMFORMING WIRELESS SYSTEM - A first embodiment is a method of calibrating an implicit beamforming wireless system wherein the implicit wireless system comprises a beamformer and a beamformee. The method comprises associating the beamformer with the beamformee, sending a sounding packet from the beamformer to the beamformee, receiving a sounding response at the beamformer wherein the sounding response contains explicit channel state information as estimated by beamformee, computing implicit channel state information at the beamformer based on transmissions from the beamformee, passing explicit and implicit channel state information into the beamformer, computing a set of compensation parameters and loading the set of compensation parameters into the beamformer thereby enabling the beamformer to implicitly beamform to a device that does not support explicit beamforming. | 07-28-2011 |

20120153718 | Thermal Management System for Use with an Integrated Motor Assembly - An integrated drive system assembly is provided that combines an electric motor, a power inverter assembly and a gearbox into a single, multi-piece enclosure. Combining these components into a single enclosure reduces weight, reduces drive system complexity, reduces system volume, simplifies assembly integration into an electric vehicle, reduces manufacturing cost, allows the flexible and lengthy electrical cables between the power inverter and the electric motor to be replaced with short, low loss, rigid bus bars, and simplifies component cooling by allowing the use of a common thermal management system. The common thermal management system includes a liquid coolant loop that is thermally coupled to the electric motor, the power inverter assembly and the gearbox. | 06-21-2012 |
20120237803 | Battery Pack Directed Venting System - A thermal management system is provided that minimizes the effects of thermal runaway within a battery pack, the system using an integrated battery venting assembly comprised of an integrated exhaust port, a valve retention plate that covers the exhaust port and includes a plurality of retention plate ports, and a plurality of valves that are configured to seal the retention plate ports under normal conditions and unseal the retention plate ports during thermal runaway. As hot gas passes through the retention plate ports, the plate is configured to melt and be ejected, thereby allowing subsequent hot gas to pass through the larger exhaust port. A perforated cover plate may be used to protect the external surfaces of the retention plate and valves. An internally mounted exhaust guide may be used to direct the flow of hot gas expelled during the thermal runaway event. | 09-20-2012 |
20130284559 | PARK LOCK FOR NARROW TRANSMISSION - A park lock of a transmission, including a park gear; a park pawl rotating about a pawl shaft, the park pawl having a pawl portion locking the park gear, the park pawl including a cam contact portion; a park rod responsive to an operation of a controller, the park rod having a cam portion pressing the cam contact portion to have park pawl engage the park gear; a park sleeve receiving the cam portion and defining a first contact point providing a reactive force to the cam contact portion of the park pawl pressing against the cam portion at a second contact point; a pawl torsional spring biasing the park pawl towards disengagement; and a pawl stopper limiting the rotation of the park pawl wherein motions are constrained within a plane of the transmission and components are rotatingly disposed in parallel axis bores in one half of a transmission case. | 10-31-2013 |
