  • Publication number: 20200198481
    Abstract: A system for a charging a vehicle is provided. The system includes a power generating device and one or more controllers. The power generating device is configured to generate a first energy signal corresponding to a requested amount of voltage for one of a vehicle and a base pad during a vehicle charging operation. The controller is configured to receive a request indicative of the requested amount of voltage to provide to the vehicle during the vehicle charging operation and to control the power generating device to generate the first energy signal based on the request. The controller is further configured to determine a resonant frequency of the first energy signal and to adjust a capacitance of a tuning capacitor network based on the determined resonant frequency to compensate for a distance variation between a vehicle pad and the base pad during the vehicle charging operation.

  • Patent number: 10594157
    Abstract: A wireless charger output protection system and method is provided for protecting a battery in an electric vehicle during wireless charging. A wireless power transfer system includes a wireless charger on the electric vehicle side that receives power wirelessly from a charging base. The wireless charger output protection system and method shuts down the wireless charger output and dumps energy in a receive antenna (e.g., a vehicle pad) when a charging error is detected before the charging base can be shut down. The system and method employs a zero-voltage switching (ZVS) scheme to shut down the wireless charger output, in response to the charging error, to protect the switching devices and enhance overall reliability.

  • Patent number: 10585108
    Abstract: Systems and methods are described to determine whether a sample transmitted through a transfer line from a remote sampling system contains a suitable sample to analyze by an analysis system. A system embodiment includes, but is not limited to, a sample receiving line configured to receive a liquid segment a first detector configured to detect the liquid segment at a first location in the sample receiving line; a second detector configured to detect the liquid segment at a second location in the sample receiving line downstream from the first location; and a controller configured to register a continuous liquid segment in the sample receiving line when the first detector and the second detector match detection states prior to the controller registering a change of state of the first detector.

  • Patent number: 10483772
    Abstract: A wireless charger output protection system and method is provided for protecting a battery in an electric vehicle during wireless charging from both a desired power source and a stray power source. A wireless power transfer system includes a wireless charger on the electric vehicle side that receives power wirelessly from a charging base. The wireless charger output protection system and method shuts down the wireless charger output and dumps energy in a receive antenna (e.g., a vehicle pad) when a low-voltage battery connected to the wireless charger is lost. The wireless charger output protection system and method also shuts down the wireless charger output and dumps unwanted energy in the receive antenna (e.g., a vehicle pad) when power is transferred from a stray power source coupled to the receive antenna.

  • Patent number: 10307930
    Abstract: A guide bar for a saw chain includes an elongate, flat base body made of a basic material. The base body extends along a longitudinal center axis and, in order to guide a saw chain, has a running surface formed on an outer periphery thereof and a guide groove formed in the outer periphery of the base body. The guide groove has a groove base. A direction-reversing section for the saw chain is provided at one end of the base body. The direction-reversing section includes at least one add-on component having a running surface made of more wear-resistant material than the basic material of the base body. The add-on component is secured to the base body of the guide bar by at least one weld seam. The weld seam extends between the add-on component and the base body and is located spatially beneath the groove base.
