  • Patent number: 10726073
    Abstract: Disclosed are systems and methods for a compiler, which can receive a computation workload, and a description of the computation graph of the workload and compile a circuit layout of the workload. In one embodiment, an RTL generator assigns the node operations of the computation graph to a first or second type. In the first type, the workload is loaded and processed in tiles equal to a compute filter width. In the second type, the workload is loaded in tiles larger in size than the width of the compute filter, allowing the compute filter to process more operations in parallel and reach the data needed for the underlying operations more efficiently.

  • Publication number: 20200128892
    Abstract: A perspiration diverting headband is provided having a flexible tubing having a first and second end, an elastic band, wherein the band is disposed within the tubing, a first connector coupled to a first end of the tubing, and a second connector coupled to a second end of the tubing, wherein the first and second connector secure the elastic band and tubing, and a slidable tension fastener configured to secure the elastic band. In addition, the tubing can be flexible tubing that is cylindrical in cross-section. Further, the flexible tubing can be configured to divert perspiration fluids away from a forehead region to a temple region of a user's head. Further, the headband can be simple to use and adjust, simple to manufacture, made of light weight moisture resistant and anti-microbial material, hygienic, and can be customized and configured to any shape, color, or design.

  • Publication number: 20200101859
    Abstract: Electric vehicle charging stations are coupled with a circuit sharing controller. Multiple electric vehicle charging stations are wired on the same electrical circuit. The circuit sharing controller implements a circuit sharing process that dynamically allocates electric current to charging stations on the same electrical circuit such that the capacity of the electrical circuit is not exceeded while permitting each of those charging stations to draw electric current through that electrical circuit for at least some amount of time.

  • Publication number: 20190381904
    Abstract: A network-controlled charge transfer device for transferring charge between a local power grid and an electric vehicle is mounted to a street light. The charge transfer device includes the following: an electrical receptacle to receive an electrical connector for connection to the electric vehicle; an electric power line that couples the power grid to the electrical receptacle through a wiring box; a control device to switch the receptacle on and off; a current measuring device to measure current flowing through the electric power line; and a controller to operate the control device and to monitor output from the current measuring device.

  • Publication number: 20190375308
    Abstract: Dynamic allocation of power modules for charging electric vehicles is described herein. A power cabinet includes multiple power modules that each are capable of supplying an amount of power to a dispenser. Multiple dispensers are coupled with the same power cabinet. A first power bus couples a first dispenser and switchably connects the power modules to the first dispenser; and a second power bus couples a second dispenser and switchably connects the power modules to the second dispenser. The power cabinet includes a control unit that is configured to cause the power modules to switchably connect and disconnect from the first power bus and the second power bus to dynamically allocate the power modules between the first dispenser and the second dispenser.

  • Publication number: 20190341661
    Abstract: An external electric vehicle battery thermal management system is described. An electric vehicle thermal system provides external coolant to an internal battery thermal system of an electric vehicle. The internal battery thermal system includes a liquid-to-liquid heat exchanger to cool or warm the set of batteries of the electric vehicle. The external coolant is pumped through a first side of the heat exchanger and serves as the source to cool or heat internal coolant pumped through a second side of the heat exchanger. The external coolant and the internal coolant do not mix.

  • Publication number: 20190296560
    Abstract: Networked electric vehicle charging stations for charging electric vehicles are coupled with an electric vehicle charging station network server that performs authorization for charging session requests while the communication connection between the charging stations and the server are operating correctly. When the communication connection is not operating correctly, the networked electric vehicle charging stations enter into a local authorization mode to perform a local authorization process for incoming charging session requests.

  • Publication number: 20190152339
    Abstract: An electric vehicle charging station network server that manages a plurality of charging stations receives subscriber notification message preferences for a subscriber (e.g., electric vehicle operator) that indicate one or more events of interest for which the subscriber wishes to receive notification messages. A set of one or more contact points associated with the subscriber is also received. The server receives data associated with the subscriber that indicates that a charging session at one of the charging stations has been established for an electric vehicle associated with the subscriber. The server detects an event of interest for the subscriber and transmits a notification message for that event to at least one of the set of contact points associated with the subscriber.

  • Patent number: 10252633
    Abstract: A first and second charging equipment for charging electric vehicles share a current capacity. A controller coupled with the first and second charging equipment limits a total amount of current drawn through the first charging equipment and the second charging equipment to not exceed the current capacity. A first and second current limit is communicated to a first and second electric vehicle respectively to limit the current draw of first and second electric vehicle to the first and second current limit respectively. A sum of the current drawn at the first and second current limit does not exceed the current capacity.
