Patent number: 9217690Abstract: An automotive battery module with one or more battery cells and a coolant loss detection and remediation system cooperative with coolant that is configured to provide thermal management of the battery module. Coolant levels in or around the battery module may be detected, while cooperation with a controller permits corrective action in the event that a leakage of coolant is detected. The controller senses a coolant level sensor which is located in a coolant reservoir to determine when the coolant level drops below a predetermined level. When the coolant level is determined to be low, the controller reports the low level condition and takes remedial action. The controller also has a set of enablement conditions that must be satisfied before the controller senses the coolant level sensor.Type: GrantFiled: January 23, 2013Date of Patent: December 22, 2015Assignee: GM Global Technology Operations LLCInventors: Scott M. Skelton, Kulwinder Singh, Richard Marsh, Doug Parks

Publication number: 20150283878Abstract: A system and method for providing a user of a hybrid electric vehicle (HEV) more flexibility and control regarding the selection of heating modes, without adversely affecting vehicle engine emissions. According to one embodiment, when the HEV is in a normal heating mode, the user is able to switch to an economy or deferred heating mode, so long as the switch takes place during the following ignition cycle. When the HEV is in an economy heating mode the user is able to switch to a normal heating mode right away, but is only allowed to do so once per ignition cycle. In both instances, the switch between heating modes is initiated by the user through a non-emissions related system, such as a vehicle infotainment module or climate control module.Type: ApplicationFiled: April 4, 2014Publication date: October 8, 2015Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: KATHY D.

Publication number: 20140302681Abstract: The embodiments disclosed herein pertain to improved methods and apparatus for etching a semiconductor substrate. A plasma grid is positioned in a reaction chamber to divide the chamber into upper and lower sub-chambers. The plasma grid may have slots of a particular aspect ratio which allow certain species to pass through from the upper sub-chamber to the lower sub-chamber. In some cases, an electron-ion plasma is generated in the upper sub-chamber. Electrons that make it through the grid to the lower sub-chamber are cooled as they pass through. In some cases, this results in an ion-ion plasma in the lower sub-chamber. The lower sub-chamber plasma has a lower electron density, lower effective electron temperature, and higher negative ion:positive ion ratio as compared to the upper sub-chamber plasma. The disclosed embodiments may result in an etching process having good center to edge uniformity, selectivity, profile angle, and Iso/Dense loading.Type: ApplicationFiled: November 15, 2013Publication date: October 9, 2014Applicant: Lam Research CorporationInventors: Alex Paterson, Harmeet Singh, Richard A.

Patent number: 8253387Abstract: Embodiments include methods for charging a battery of an electrical system. The electrical system includes the battery, a battery charger, and a controller. The battery charger is adapted to produce an output power in response to a control signal from the controller. The controller is adapted to control a battery charging process by determining a temperature of the battery pack, determining a voltage setpoint for the battery charger based on the temperature, and providing the control signal to the battery charger. According to an embodiment, when the temperature of the battery exceeds a first temperature value, the battery charging process is temporarily suspended prior to satisfying a charging termination criterion. Determining the temperature of the battery is repeated, and when the temperature of the battery is less than a second temperature value, the battery charging process is resumed.Type: GrantFiled: April 24, 2009Date of Patent: August 28, 2012Assignee: GM Global Technology Operations LLCInventors: Vernon L.
