  • Patent number: 11951799
    Abstract: A thermal management system for an electrified vehicle and a method for managing such a system, includes a coolant subsystem to cool a battery pack and a refrigerant subsystem. The coolant subsystem includes a battery chiller in fluid communication with a cooling system inlet to the battery pack. The refrigerant subsystem includes a chiller cooling subsystem to cool the battery chiller and a cabin cooling subsystem to cool a passenger cabin, wherein the chiller cooling subsystem and the cabin cooling subsystem are completely separate from each other.

  • Patent number: 9066323
    Abstract: Example disclosed herein relate to an ad hoc network connection. A first mobile device initiates a request for an ad hoc wireless local area network (WLAN) connection with a second mobile device via a cellular network. Location information of the second mobile device is received and a distance of the second mobile device to the first mobile device is determined from the location information. If the distance is within a threshold, the first mobile device and the second mobile device exchange WLAN parameters and the ad hoc WLAN connection is established using the WLAN parameters.

  • Patent number: 4209178
    Abstract: A lubricant seal for an oil lubricated ball bearing journalling a shaft within the cavity of a stationary housing. The lubricant seal comprises an annular rigid oil sling affixed to the shaft within the cavity. The oil slinger is formed of an oil absorbing material adapted at low or nonrotational speed of the shaft to absorb excess oil within the housing cavity and at high speed to centrifuge oil into the bearing.

  • Patent number: 4194119
    Abstract: An assembly for transferring heat at cryogenic temperatures across an interface space between a relatively fixed refrigerated cold finger and a relatively movable Dewar vacuum flask having an infrared detector array mounted therein. The interface assembly is formed of two opposing thermal conducting plates which are spring loaded so as to be in intimate contact with both the end face of the cold finger and a face of the opposite side of the mounting element for the detector array in the Dewar vacuum flask. A flexible thermal conductor element surrounds the spring and is securely connected to the opposing plates to complete the thermal conduction path between the flask and the cold finger. A first preferred embodiment of the assembly utilizes a bellows shaped flexible thermal conductor which allows the plates to make intimate contact with their corresponding faces even though the faces may be oriented in non-parallel configurations.
