  • Patent number: 12339264
    Abstract: Calibration methods for lidar equipment are disclosed. In some embodiments, the lidar equipment is provided with an internal gas reference cell with a known concentration of the gas of interest, such as methane (CH4), which provides known absorptions at wavelengths particular to the gas. The lidar system laser beam passes through the gas reference cell before scanning a scene, and provides a known level of gas absorption at those known absorption wavelengths. This guarantees there is a minimum signal to be detected by the lidar system. In some embodiments, the lidar equipment is provided with an external calibration unit having one or more gas sample cells with predetermined lengths and known concentrations of the gas of interest. By making lidar measurements using an arrangement of these calibrated cells, adjustments to the parameters used in the algorithms relating detected photon counts with gas concentration may be made.

  • Patent number: 12326300
    Abstract: A system includes a heat exchanger that includes a relatively hotter process gas inlet and an exit port, a moisture removing filter coupled to the exit port, the moisture removing filter including a relatively colder gas exit, and a drain valve coupled to the moisture removing filter. The heat exchanger, the moisture removing filter, and the drain valve are all located in a thermally-insulated enclosure. A fan is placed outside the thermally-insulated enclosure and forces ambient air over the heat exchanger. The ambient air is sufficient to maintain a temperature above a water freezing temperature in the thermally-insulated enclosure even if the ambient air is below the water freezing temperature.

  • Patent number: 12301088
    Abstract: A system and method of producing electricity is provided. Fluid is pumped from a feed tank to a steam generator using a pump. The steam generator has a high temperature heater for heating the fluid and increasing pressure before the fluid travels to a steam chamber. The fluid flows from the steam generator to the steam chamber. At least one chemical that creates an exothermic reaction is injected into an ignition chamber and the chemical reaction is initiated using an igniter. The exothermic reaction increases the energy available in the system. Fluid from the steam chamber flows through a steam turbine to generate electricity.

  • 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.
