  • Patent number: 7574920
    Abstract: A pressure gauge is provided for monitoring pressure within a reservoir, such as air within a vehicle tire. The gauge is particularly configured to allow it to remain upon a valve stem of the tire even when the tire is in operation. A receiver of the gauge can be coupled to the valve stem. A valve core is preferably provided through which air can pass from a compressed air source, so that the tire can be filled without removing the gauge. A Bourdon tube is located within a sensor chamber and measures pressure within the reservoir. A shroud or other support surface is located adjacent a central opening of the Bourdon tube so that the Bourdon tube is supported sufficiently to avoid damage from forces including centrifugal forces encountered when the tire is spinning and the gauge is mounted on the valve stem of the tire.

  • Patent number: 7565832
    Abstract: A tire pressure detector includes an electrically conductive housing having a housing body and a protruding annular body; a cover having a sleeve portion connected to the protruding annular body, an airtight chamber defined by the cover and the housing for receiving a battery device, a PCB and a first electrically conductive resilient member, the housing body or the cover being disposed with an air intake mouth; and the PCB having a pressure and temperature detecting device. The air intake mouth guides air inside the tire to flow into the airtight chamber. The pressure and temperature detecting device detects the pressure and temperature of the air inside the tire and transmits data to the microprocessor for processing. The microprocessor controls the transmitter to transmit a signal. A receiver disposed near a driver's seat receives and processes the signal and then displays the tire pressure and temperature value on a display.

  • Patent number: 7488106
    Abstract: An automated apparatus for determining the calorific value of combustible substances employs an integrated, isothermal water reservoir to reduce the complexity of the apparatus and facilitates automation of the calorimeter by providing a convenient source of isothermal water. A moving divider is used to reconfigure the isothermal water reservoir to either provide for temperature equilibration prior to sample analysis or define a fixed volume of water during analysis in which high precision temperature measurements can be recorded. The apparatus includes mechanisms for controlling the moving divider, a sample holding combustion vessel, and loading, cleaning, and unloading the combustion vessel. This eliminates key analysis steps that had previously required manual intervention by an operator.

  • Patent number: 7484427
    Abstract: The apparatus of the present invention comprises a tool having a threaded member which is characterized by a cylindrical shaft or spindle with a surrounding body or handle. The shaft and body are operably engaged by means of a series of magnets in the spindle and the body, and the operable engagement releases once the torque force on the threaded member exceeds the magnetic force between the body and the spindle. In the method of the present invention, the user can calibrate and adjust the torque limit of the assembly by attaching a calibration bar of predetermined length to the threaded member and then rotating the tool over a scale such that the calibration bar contacts the surface of the scale. The user can then adjust a set screw which alters the length of the shaft and alters the magnetic force between the body and the spindle and correspondingly alters the torque limit of the tool to a desired level.

  • Patent number: 7484886
    Abstract: Disclosed are embodiments of an improved on-chip temperature sensing circuit, based on bolometry, which provides self calibration of the on-chip temperature sensors for ideality and an associated method of sensing temperature at a specific on-chip location. The circuit comprises a temperature sensor, an identical reference sensor with a thermally coupled heater and a comparator. The comparator is adapted to receive and compare the outputs from both the temperature and reference sensors and to drive the heater with current until the outputs match. Based on the current forced into the heater, the temperature rise of the reference sensor can be calculated, which in this state, is equal to that of the temperature sensor.
