    Abstract: 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.

    Abstract translation: 泵可以具有第一室和电磁线圈，以控制第一阀构件的运动。 第二室可以具有第二阀构件以控制流入第三室的流体。 第一流体通道可以连接第一和第二腔室，第二通道可以连接第二和第三腔室，第三通道可以连接第三和第四腔室。 在加压第三室，使流体流入并离开第四室之后，第三室由于柱塞的向下运动而减压。 在用螺线管线圈通电的情况下进行减压，第二阀构件浮动然后抵靠阀座移动。 当第二阀构件朝向阀座移动时，当第二阀构件以最大速度移动时，螺线管线圈断电，使得第一阀构件移动并撞击第二阀构件。

    Abstract: A pedestrian collision warning system includes a transceiver, a memory and a control module. The transceiver receives a PSM and a map message at a vehicle. The memory stores map data. The control module: based on the messages, determines possible conflict boxes in which the vehicle and a pedestrian are predicted to be in at a same time; based on the map data and the map message, determines a most likely path of the vehicle through the intersection from possible intersection paths; based on the most likely path of the vehicle and the possible conflict boxes, determines whether the vehicle and the pedestrian will be in a possible conflict box at a same time; and in response to determining that the vehicle and the pedestrian will be in a possible conflict box at a same time, alerts an occupant of the vehicle or the pedestrian of a potential collision.

    Abstract: A remote station includes a transceiver, a memory and a control module. The memory is configured to store first path data of vehicles through an intersection. The control module is configured to (i) receive at least one of road obstruction information or current vehicle path information, (ii) update the first path data based on the at least one of the road obstruction information or the current vehicle path information, and (iii) broadcast via the transceiver a first map message including the updated first path data, the map message includes a first plurality of data elements, wherein the first plurality of data elements defining a vehicle path through the intersection.

    Abstract: A path prediction system includes a transceiver, a memory and a control module. The transceiver is configured to receive a map message at a host vehicle, the map message comprising path information of vehicles through an intersection. The memory is configured to store map data including global navigation satellite system information. The control module is configured to (i) determine if the host vehicle is approaching, at or in an intersection based on the map data, (ii) in response to determining that the host vehicle is approaching, at or in the intersection, predict a path of the host vehicle through the intersection based on the path information, and (iii) based on the predicted path of the host vehicle, perform at least one collision warning operation.
