  • Patent number: 10473925
    Abstract: A self-cleaning lens system disposed adjacent a camera is disposed. The system may incorporate a piezoelectric (PZT) lens system having a first PZT element secured to a first peripheral portion of the lens element, which may be responsive to an alternating current (AC) signal applied to the first PZT element. An AC signal may excite the first PZT element to cause shear displacements in opposite longitudinal directions and to create an oscillating shear motion for the first PZT element. The oscillating shear motion may cause an oscillating rotational movement of the lens element that removes the environmental element from a surface of the lens element.

  • Patent number: 9446681
    Abstract: A battery pack and method of cooling a battery pack. In one form, the battery pack is an assembly made up of numerous battery cells arranged within numerous modules. Cooling channels that receive cooling fluid from a ducted supply are placed between adjacent cells or cooling plates within each of the modules. The ducted supply includes beads or related area-increasing undulations that are designed to improve both the stiffness of the ducting as well as the uniformity of the flow rates of individual cooling channels within each of the modules. In one form, the pressure-enhancing beads are placed in an inlet portion of the ducting that is adjacent a forward portion of one or more of the sequentially-encountered modules in order to promote a more equitable distribution of the cooling fluid between the various cooling channels within each of the modules.

  • Patent number: 8999548
    Abstract: A battery module having a cooling plate assembly made from two non-contiguous cooling plates is provided. Each cooling plate has a side panel contiguous with a base panel, and the cooling plates are disposed opposite one another such that the base panels are coplanar and separated by a gap. An inlet duct runs along an upper edge of each side panel, and a manifold having coolant channels in fluid communication with the inlet duct is located in each side panel. The base panels have an outlet duct in fluid communication with the manifold. The cooling plate is designed to decrease friction loss as coolant flows through the inlet duct, manifold and outlet cut, and coolant channels in the manifold are designed to maintain a uniform flow rate across the manifold. Individual cells are disposed in the assembly such that the cell sides and bottoms are in heat-transfer contact with the plate side and base panels, respectively.

  • Publication number: 20110151868
    Abstract: The present invention aims to provide a technical solution for the caller can call the user equipments in the specific area without knowing the numbers of the user equipments first. A querying device sends a first querying request message to a querying response server to query the user equipments in the specific area. The querying server sends a first querying response message comprising the relevant information of the user equipments in the specific area back to the querying device. The relevant information includes the communication identifier (such as number). The caller then can communicate with the user equipment in the specific area according to the first querying response message. The present invention enhances the existing location services and provides the reversed style location service to users or customers and helps to improve the users' experiences in communication.
