  • Publication number: 20240133867
    Abstract: A breath capture and analysis system includes a breath inlet for capturing a user's breath. The breath is drawn into the system and retained for analysis. The system includes a membrane that allows volatile organic compounds contained in the breath to pass therethrough. The volatile organic compounds pass into a vacuum chamber that includes a residual gas analyzer that is configured to analyze the volatile organic compounds. The analyzed breath is then vacated from the system.

  • Publication number: 20240052797
    Abstract: A method for operation of a closed-cycle power conversion device includes receiving measured thermal information from one or more sensors that sense thermal characteristics of a hot portion of an absorber heat exchanger of a closed-cycle power conversion device which uses a working medium in its operation. The closed-cycle power conversion device is in thermal connection with a heat source, and absorption of heat from the heat source is proportional to a mass or mass flow rate of the working medium. If the measured thermal information is not in a defined normal range, a message is provided of an abnormality in operation of the closed-cycle power conversion device.

  • Publication number: 20190264765
    Abstract: A brake pad wear measuring system is for use on a vehicle equipped with a tire pressure monitoring (TPM) system including a wheel mounted TPM sensor, and a floating caliper disc brake system including a piston supporting an inner brake pad and a floating caliper supporting an outer brake pad, wherein the piston and floating caliper move toward each other along a braking axis in response to application of the brake system so that the brake pads engage and apply a braking force to a brake rotor. The brake pad wear system includes a permanent magnet attached to the floating caliper. The permanent magnet generates a magnetic field and being positioned on the floating caliper so that the TPM sensor of the wheel passes through the magnetic field as the wheel rotates during vehicle operation. The system also includes a field sensor implemented in the TPM sensor. The field sensor detects the magnetic field as the TPM sensor passes through the magnetic field.

The brake pad wear system includes a sensor mounted on the floating caliper and movable with the floating caliper along the braking axis and an actuator mounted for movement with the piston along the braking axis. The sensor and actuator move toward each other in response to application of the disc brake system. The distance that the sensor and actuator move toward each other in response to application of the disc brake system increases an amount that is equal to the total wear of the inner and outer brake pads. The sensor is responsive to the presence of the actuator to provide a signal indicative of brake pad wear.

  • Patent number: 10337576
    Abstract: A brake pad wear measuring system for measuring brake pad wear for a vehicle disc brake system includes a first coil excitable to create a first magnetic field, and a first target associated with the first coil. The first coil and the first target are configured for movement relative to each other in response to application of the disc brake system. The relative movement causes the first target to move within the first magnetic field and affect the inductance of the first coil. The brake pad wear measuring system also includes a second coil excitable to create a second magnetic field, and a second target associated with the second coil. The second coil and the second target are configured for movement relative to each other in response to application of the disc brake system. The relative movement causes the second target to move within the second magnetic field and affect the inductance of the second coil.
