Patent number: 11961403Abstract: A system for generating virtual lane markers of an intersection so that the virtual lane markers are visible to an operator of a vehicle at the intersection. The system includes a remote station having a transceiver, a remote memory module configured to store map data and baseline static paths of vehicles moving through the intersection, and a remote control module configured to broadcast via the transceiver a map message indicating the baseline static paths. A vehicle transceiver is configured to receive the map message.

Patent number: 9945373Abstract: A pump may have a first chamber and a solenoid coil to control movement of a first valve member. A second chamber may have a second valve member to control fluid moving into a third chamber. A first fluid passageway may link the first and second chambers, a second passageway may link second and third chambers and a third passageway may link third and fourth chambers. After pressurizing the third chamber causing fluid to flow into and leave a fourth chamber, the third chamber depressurizes due to downward movement of a plunger. Upon depressurization with a solenoid coil energized, second valve member floats and then moves against a valve seat. While the second valve member is moving toward the valve seat, the solenoid coil is de-energized causing the first valve member to move and strike the second valve member when the second valve member is moving at maximum velocity.Type: GrantFiled: June 21, 2016Date of Patent: April 17, 2018Assignees: DENSO International America, Inc., DENSO CORPORATIONInventors: Tsutomu Furuhashi, Rebecca Spence, Joseph Lubinski, Dhyana Ramamurthy, Kaoru Oda
