  • Patent number: 11815722
    Abstract: Reversible optical connectors, and associated devices and methods are provided. In one embodiment, a connector for a communication cable includes a housing comprising a cavity, and a first plug and a second plug coupled to a distal portion of the housing. The first and second plugs are connected to the housing such that the first and second plugs are independently rotatable with respect to the housing. The connector further includes a latch actuator coupled to the housing and configured to disengage one or more latches from an outlet. By rotating the plugs 180 degrees and turning the connector over, the relative arrangement or position of the two plugs can be switched or reversed. The plugs can be rotated or reversed without completely disassembling the connector, in some embodiments. Accordingly, embodiments of the present disclosure can improve workflows for a user or operator that in a high-density networking setting.

  • Patent number: 8996213
    Abstract: A charge control system for charging a battery in an electric motor vehicle includes a travel history database, a route information acquisition unit, a power consumption estimation unit, and a charge control unit. The travel history database stores data of actual travel history from a plurality of electric motor vehicles. The route information acquisition unit determines a planned travel route toward a destination specified by a user, and the power consumption estimation unit calculates an estimated power amount of the battery for the travel of the electric motor vehicle along the planned travel route. The charge control unit controls a charge of the battery based on the estimated power amount. The estimated power amount is based on data in the travel history database from a same-type vehicle as the electric motor vehicle and a same travel route as the planned travel route.

  • Patent number: 7532975
    Abstract: A vehicle is provided with a plurality of imaging cameras for imaging the front left side, front right side, rear left side, rear right side and rear side. Imaging conditions such as a position where the imaging is scheduled, imaging camera used for the imaging, vehicle traveling direction, shift position of a transmission and vehicle speed are registered in an external memory. When the present position of the vehicle detected by a position detector is at or close to the position where the imaging is scheduled and when the imaging conditions are satisfied, the external circumstances of the vehicle are imaged by the specified imaging camera and are displayed on the display unit in the vehicle.
