Patent number: 9744877Abstract: A cooling system for a vehicular fuel cell utilizes packet pumps to electrically isolate the fuel from a grounded radiator. Fluid in a packet pump is transported from an inlet port to an outlet port in discrete packets. Because these packets are physically separated from one another, electricity does not flow through the fluid from the inlet port to the outlet port. Packet pumps include peristaltic pumps and external gear pumps.Type: GrantFiled: August 11, 2014Date of Patent: August 29, 2017Assignee: Ford Global Technologies, LLCInventors: Allan Roy Gale, John Peter Bilezikjian, Richard William Kautz

Patent number: 9656552Abstract: Systems, apparatus and methods for cancelling a noise voltage at a vehicle are presented. An noise cancellation system (NCS) can be configured to null an earth-to-body voltage at the vehicle to prevent its interference with a receiver system. An (NCS) can include a noise sensor (NSSR) configured to sense a noise voltage, and a noise-nulling device (NNDV) configured to provide an anti-noise output. An anti-noise injector (ANI) can be configured to drive the anti-noise output at an anti-noise injection site In an example embodiment, an anti-noise output can be provided directly to the receiver system by cable. Alternatively, an anti-noise signal can be inductively or capacitively coupled to a vehicle structure or component that is not part of the receiver system. A noise cancellation system can be arranged in a feedback or feed-forward arrangement. Radio frequency noise and non-radio frequency noise can be cancelled.Type: GrantFiled: November 5, 2014Date of Patent: May 23, 2017Assignee: Ford Global Technologies, LLCInventor: Richard William Kautz
