20100025125	Method and Apparatus for the Operation of a Vehicle - In a method and apparatus for the operation of a vehicle having a battery with a plurality of series or parallel connected individual cells, a coolant flows through the respective cell housings and/or a battery housing that encloses the entire battery. The coolant is delivered within a coolant circuit by a pump unit, and is thermally coupled with a refrigerant circuit through a heat exchanger. A refrigeration compressor placed in the refrigerant circuit is thermally coupled with the coolant circuit through the heat exchanger, depending on a current ambient temperature and/or a current speed of the vehicle. The speed of the refrigeration compressor may be regulated depending on the current ambient temperature and/or the current speed of the vehicle.	02-04-2010

20090299529	EFFICIENT AC OPERATION USING DEW-POINT TEMPERATURE - A system for controlling air-conditioning in a vehicle includes an input, a sensor, a first offset module, and an evaporator temperature control module. The input receives an input temperature. The first sensor measures a first dewpoint temperature of air adjacent to a windshield of the vehicle. The first offset module generates a second dewpoint temperature based on the input temperature and generates a first offset based on the first and second dewpoint temperatures. The evaporator temperature control module generates a target evaporator temperature based on the first offset.	12-03-2009
20090299533	EFFICIENT AC OPERATION USING DEW-POINT TEMPERATURE - A system for controlling air-conditioning of a vehicle includes an input, an offset generator module, and an evaporator temperature control module. The input receives an input temperature. The offset generator module receives a psychrometric parameter of air inside the vehicle and generates offsets based on the input temperature and the psychrometric parameter. The evaporator temperature control module generates a target evaporator temperature based on the offsets.	12-03-2009

20090272112	TURBOCHARGER WITH VARIABLE NOZZLE HAVING VANE SEALING SURFACES - A variable nozzle for a turbocharger includes a plurality of vanes rotatably mounted on a nozzle ring and disposed in a nozzle flow path defined between the nozzle ring and an opposite nozzle wall. Either or both of the faces of the nozzle ring and nozzle wall include(s) at least one step that defines sealing surfaces positioned to be substantially abutted by airfoil surfaces of the vanes in the closed position of the vanes and to be spaced from the airfoil surfaces in positions other than the closed position. This substantial abutment between the airfoil surfaces and the sealing surfaces serves to substantially prevent exhaust gas from leaking past the ends of the airfoil portions. At the same time, clearances between the nozzle ring face and the end faces of the airfoil portions can be sufficiently large to prevent binding of the vanes under all operating conditions.	11-05-2009
