  • Patent number: 9212619
    Abstract: A method for preventing misdiagnosis of an oil level sensor may include determining whether a driving status of a vehicle satisfies a first diagnosis condition, a second diagnosis condition or both. When the first diagnosis condition is satisfied, the method may include measuring oil levels, calculating a first average of the measured oil levels, and comparing the calculated first average of the measured oil levels with a predetermined reference oil level. When the second diagnosis condition is satisfied, the method may include measuring oil levels, calculating a second average of the measured oil levels, and comparing the calculated second average of the measured oil levels with the predetermined reference oil level. The method may also include warning an excess of oil when the first, the second or both first and second averages of the measured oil levels are higher than the predetermined reference oil level.

  • Patent number: 9163973
    Abstract: A method for identifying an undesired condition in the function of a floating roof of a tank, the method comprising determining a filling level of a product in the tank, detecting a reference distance between a reference position on the roof and the surface using a level gauge mounted on the roof, forming a reference distance deviation as a difference between the reference distance and an expected value, and comparing the reference distance deviation with a specified range. If the reference distance deviation is outside the specified range, a data set including the reference distance deviation and the filling level is stored. These steps are repeated for a plurality of points in time, and the undesired condition is then identified based on stored data sets of reference distance deviations and filling levels. The present invention thus provides an economical method to provide diagnostics of a floating tank roof.

  • Patent number: 7874724
    Abstract: Two vertically offset thermistors for sensing a fluid such as oil and refrigerant in a compressor shell are monitored by a method that takes into account rapidly changing conditions within the shell. The system can determine the fluid's sump temperature, high/low liquid levels, and can determine whether the thermistors are sensing the fluid as a liquid, gas, or a mixture of the two, such as a foam or mist of liquid and gas. For greater accuracy, thermistor readings can be dithered and filtered to provide temperature or voltage values having more significant digits than the readings originally processed through a limited-bit A/D converter. For faster response, limited microprocessor time is conserved by sampling thermistor readings at strategic periods that enable the microprocessor to identify certain conditions and temperatures via simple delta-temperature ratios and undemanding equations rather than resorting to exponential functions or lookup tables to determine time constants.

  • Patent number: 7852201
    Abstract: A vehicle has a transmission, a transmission filter, and a controller having an algorithm or method for predicting the remaining useful life of the filter. The algorithm or method uses a sensor to detect an operating event of the transmission, such as a completed shift event or zero transmission output speed event, and increases a stored value of an accumulated distance and time variable. A shift sensor is operable for comparing a detected speed ratio of the transmission to a stored threshold speed ratio for determining the completed shift event. The remaining useful filter life is predicted using one or more look up tables using the values of the accumulated distance and time variables. The accumulated distance is calculated in part by dividing a prior recorded accumulated distance value by a ratio of an output speed of the transmission to an actual vehicle speed.

  • Patent number: 7721601
    Abstract: A hydrogen storage tank for containing solid-state hydrogen storage media, and method for determining the hydrogen fill level in the tank. The tank has at least one compartment for storing the storage media, passages for transporting hydrogen gas to and from the compartment, and a heat distribution system for establishing a substantially uniform temperature in the storage media. A look-up table is generated for the tank that relates hydrogen pressure changes in the tank versus hydrogen fill levels in the tank as a function of temperature. The tank is filled to full capacity by adsorbing hydrogen on the storage media. Thereafter, hydrogen is released from the storage media for a time period during which there is a substantially constant demand on the tank, the change in pressure of the released hydrogen gas is measured, and the look-up table is applied to determine the hydrogen fill level in the tank.

  • Publication number: 20090288483
    Abstract: A water level and temperature indicating device useful for signaling preset desired water levels in a bath tub and indicating air and bathwater temperature. The device has suction cup means for removably securing the device to the tub ledge. A depending float chamber and temperature probe for projecting into the bathtub, a battery operated audible alarm system and a battery operated digital thermometer device. An interchangeable weighted float of various lengths is housed within a float chamber. The float chamber has a removable screen unit to facilitate float changes which determine desired preset water level. A modified push on switch within the float chamber will complete an electrical circuit and sound an alarm when a desired preset water level is achieved. The thermometer device will indicate air temperature until it makes contact with the water. While in contact with water the thermometer device indicates water temperature.

  • Publication number: 20090093983
    Abstract: It is described a method to measure a fill level of a material by transmitting an ultrasonic or microwave signal towards a surface of the material using a level gauge arranged above the material surface, receiving in said level gauge an ultrasonic or microwave signal portion reflected from said material surface, measuring a temperature at least one measurement point between the level gauge and the material surface and determining in a calculation unit of the level gauge a temperature-corrected value of the fill level based on the time delay of the received signal portion with respect to the emitted signal and the measured temperature. To provide an improved level measuring method and system with increased reactivity and accuracy in compensating temperature variations at least one non-contact infrared thermometer is used to measure the temperature.

  • Patent number: 7487676
    Abstract: A method of and apparatus for measuring a level of a liquid stored under pressure in a reservoir ensure that the level is measured precisely even when a carrier gas is bubbled through the liquid. A tube extends in the reservoir such that a lower end of the tube is immersed in the liquid and that the liquid occupies a portion of the tube, and a first gas that is insoluble in the liquid is sealed in the upper portion of the tube. A detecting unit detects changes in density of the insoluble gas as the level of the liquid changes. The apparatus is employed in a deposition apparatus where the liquid is used to produce a source gas for forming a layer on a substrate. A carrier gas, bubbled through the liquid in the reservoir, transports gas produced from the liquid to a process chamber in which the deposition process takes place.

  • Patent number: 7483795
    Abstract: A method of determining a temperature and a pressure in a tank is provided. The method comprises the steps of obtaining sensor data and calculating coefficients. Then, a bridge resistance is ratiometrically determined from a bridge voltage. A temperature is calculated with the coefficients and the bridge resistance. Thereafter, a transition from a temperature measurement mode to a pressure measurement mode is made. A voltage per resistance is calculated with the coefficients and a differential voltage. Then, a normalized voltage is calculated using the voltage per resistance, the differential voltage, and the bridge resistance to indirectly compensating for temperature. A pressure is calculated with the coefficients and the normalized voltage.
