  • Patent number: 11662018
    Abstract: A method and a system of diagnosing a vehicle oil leak are capable of detecting an oil leak state of transmission oil on the basis of logic. The method includes an operating condition determination step of determining, by a controller, whether a minimum operating condition of a vehicle is satisfied. The minimum operating condition is required to normally generate a target line pressure by operating an EOP. The method includes a counting step of counting, by the controller, an operating time of the EOP when the minimum operating condition is satisfied and includes an oil leak diagnosis step of diagnosing, by the controller, an oil leak when the counted continuous operating time of the EOP is a permissible time or more.

  • Patent number: 11659657
    Abstract: A flexible circuit package. The circuit package includes a termination point on a flexible base substrate. The termination point is connected with an interface by conductive material on the base substrate. The conductive material extends across the surface area of the base substrate in multiple individual connections, which are in communication with each other and separated by voids in the conductive material for mitigating communication failure between the termination point and the interface during or following flexion, stretching, compression or other deformation of the base substrate and the circuit package. The termination point may include an input module such as a sensor, switch or other input. The termination point may include an output module such as a light, vibrator or other output. The interface may include an output interface for receiving data or an input interface for sending a command or other signal.

  • Patent number: 11641974
    Abstract: A method and apparatus for venting a liquid supply of a beverage machine, e.g., by permanently open orifice and/or pressure relief valve. The orifice may always vent a heater tank, even while liquid is delivered to the tank by a liquid pump and/or while the tank is pressurized by an air pump to deliver liquid from the tank. A filter may be positioned between a heater tank and orifice and/or air pump. The pressure relief valve may be positioned between the liquid pump and the inlet side of the heater tank, e.g., so relatively cool water is released by the pressure relief valve when open.
