  • Patent number: 10935455
    Abstract: A method and system for detecting small leaks in a plumbing system is disclosed. A temperature sensor coupled to the water in the plumbing system is used to determine if there is a leak. During times of inactivity for fixtures in the plumbing systems, a flow sensor might measure usage of water that would indicate a leak. For very small leaks, the flow is below a minimum measurable flow of the flow sensor. Embodiments of the invention measure temperature of water within a pipe coupled to the plumbing system. Temperature will generally decay in a particular predicable way when there is flow as the temperature of water upon entry to the building is lower than the air temperature within the building. Signal processing, machine learning and/or statistical approaches are used to analyze the temperature and optionally flow and/or pressure over time to determine when a leak is likely.

  • Patent number: 10704546
    Abstract: A service module for troubleshooting a pumping unit, particularly that used in the oil/gas industry, is operatively coupled between a motor of the pumping unit and a high pressure shutoff sensor which acts to kill the motor of the pumping unit in the event a pressure of the pipeline exceeds a prescribed threshold. The service module is operable in a first normal operating mode in which the shutoff sensor acts as it normally would to shut off the motor when the prescribed threshold is exceeded, and in a second troubleshooting mode where the normal operation of the shutoff sensor is bypassed for a predetermined period of time. After the predetermined period of time of the second troubleshooting mode has elapsed, the service module automatically returns to the normal operating mode. The shutoff sensor thus remains operatively coupled to the motor during troubleshooting of the motor.

One of the compartment body and cap retainer can have internal threads to be screwed onto external threads of the other one of the compartment body and cap retainer. The cap retainer can also have a stopping feature to keep the sealing cap in its sealed position. The watertight electrical compartment can be used in a wireless flow sensor assembly, a battery operated irrigation controller, and/or a battery-operated central controller device, to provide irrigation control, and/or sensor information, without the need for AC power.

  • Patent number: 10190587
    Abstract: A motor-driven compressor includes an electric motor including a rotor, a housing, a compression unit, a drive circuit, and a controller. The controller includes a deceleration controller that performs a deceleration control, which decelerates the rotor, during a first period in response to the rotor being rotating in a direction opposite to the forward direction, and a continuation controller that performs a continuation control, which continues the rotation of the rotor, during a second period that is longer than the first period after the deceleration control is performed. A fluctuation difference of a rotational frequency of the rotor during the continuation control is less than a deceleration rotational frequency difference.

  • Patent number: 9964325
    Abstract: An air conditioning system includes an outdoor unit, indoor units, a controller that controls the outdoor unit, and an equipment controller. The equipment controller stores a set lower limit value that is set to maintain a pressure difference between the high pressure and the low pressure in the outdoor unit at a predetermined value or greater. The lower limit value is set to be smaller as a minimum cooling capacity increases. The minimum cooling capacity is the minimum value of a cooling capacity of an indoor unit arrangement formed by the indoor units. When starting a cooling operation, the equipment controller determines whether or not to perform pressure difference control for limiting decreases in the pressure difference of the outdoor unit based on whether or not the temperature of water flowing into the outdoor unit is less than the set lower limit value.

  • Patent number: 9810212
    Abstract: A pump apparatus has a downhole pump disposed in a wellbore and has motor at a surface of the wellbore, and the downhole pump is reciprocated in the wellbore by a rod string operatively moved by the motor. A card indicative of load and position of the downhole pump is generated using surface measurements and a wave equation model having a damping factor or two damping factors. Actual fluid load lines are determined from the downhole card for upstroke and downstroke of the downhole pump, and calculated fluid load lines from the load distribution of the downhole data. The actual fluid load lines are compared to the calculated fluid load lines so that at least one parameter of the pump apparatus can be modified based on the comparison. For example, the damping of the wave equation model can be adjusted so that another downhole card can be generated.

  • Patent number: 9797394
    Abstract: An improved air compressor includes a cylinder fitted with a piston body and an air storage container. The cylinder and the air storage container are detachably assembled to define an air chamber. A metal seat with a through hole is provided on top of the cylinder. A valve plug is spring-biased against the metal seat. The air storage container is provided with a pressure indicator, which includes a tube defining therein a first bore and a second bore, between which a tapered annular surface is formed. When the air pressure within the air storage container exceeds a predetermined pressure set for the air compressor, the pressure indicator allows excess air to flow into the first bore of the tube and sequentially pass through the tapered annular surface and an elongated opening to be released to the ambient environment, so that objects can be prevented from damages due to excessive inflations.
