  • Patent number: 8760302
    Abstract: A dewatering system includes a selective calibrating sensor circuit configured to receive sensor readings from an electronic sensor, to determine if the electronic sensor is immersed in water, to allow a user to adjust a pump down time in the field, and to generate a control output signal accordingly. The selective calibrating sensor circuit periodically performs a self-calibration when the electronic sensor is not immersed in water to cancel the effect of potential contaminants deposited on the electronic sensor over its operating life. The selective calibrating sensor circuit inhibits calibration when the electronic sensor is immersed in water. In some applications with multiple electronic sensors, the selective calibrating sensor circuit disconnects from one of the electronic sensors before performing the self-calibration. In certain embodiments, a pump control circuit including the selective calibration sensor circuit can be configured to be mounted with a housing of the pump.

  • Patent number: 8410948
    Abstract: A wastewater holding tank sensor probe for use in determining the presence of a conductive liquid held within a wastewater holding tank in a recreational vehicle is disclosed. The probe is less sensitive to the presence of conductive residue as a result of an improved geometry and/or choice of materials that reduce the leakage currents between the probe tip and the sensor probe attachment surface, typically the wall of the tank. This reduction in sensitivity to conductive residue buildup can be measured by a geometrically determined resistivity factor between the probe tip and the mounting surface of the probe. The reduction in sensitivity can also be measured by the length of the path through the conductive residue between the probe tip and the mounting surface of the probe. A variety of geometries and material choices to reduce the sensitivity of electrical conductance based sensor probes to conductive residue are disclosed.

  • Patent number: 7821411
    Abstract: A noninvasive security device for detection of blocked fluid flow within a conduit includes clamping body that may be affixed to the conduit and a safety overflow circuit mounted to the clamping body. The safety overflow circuit includes first and second sensor pads that act as the metal plates of a capacitor. The sensor pads are connected to the clamping body and positioned proximate the conduit to measure the capacitance within the conduit. The capacitance will be low when water is freely flowing through the conduit, since the dielectric constant will be similar to that of air. However, when the water level increases in the conduit, the dielectric constant will increase as will the capacitance, such that a pulse signal is generated to notify the user of the occlusion and to further disable the source of the water to the conduit.

  • Patent number: 7760105
    Abstract: A water detection and alarm system to monitor household plumbing fixtures for leaks. A wick attached to a water activated battery cell connects to a charge accumulator, pulse timer, and audio transducer. The wick draws water from the leak and transports it into the battery cell. A sponge inside the cell absorbs the water and expands, chemically activating the cell, and subsequently providing the electrical energy for the charge accumulator and timer. The timer utilizes the energy stored in the charge accumulator to generate a pulse that drives an audio transducer. No conventional battery is used or required; thus periodic battery replacement is not necessary nor is there a need for a battery monitoring circuit to test for battery depletion.

  • Patent number: 6898499
    Abstract: A control system enables a considerable decrease in electric power consumption of backup power, leading to effective prevention of a dead battery, while data in each control unit which need be maintained even after power is turned off is properly maintained. An ECU has a first transmitter to transmit data which need be maintained to an ECU for storage when a change in position of an IGSW connected to a battery to the off position is detected, and a power supply cutoff circuit to cut off the power supply to the other ECUs after the completion of the transmission of data to the ECU for storage by the first transmitter, wherein the ECU for storage has a first storage controller to store the data transmitted from the other ECUs in RAM, and a power switching circuit to detect the change of the IGSW to the off position and switch the power of the ECU for storage to the backup power.

  • Patent number: 6476723
    Abstract: Insulating oil in electric power transmission devices such as a transformer is filtered for removal of accumulated water and carbon particles. The filter and circulation pump are usually located in a separate cabinet external to the transformer with circulation conduits connecting the filter, the pump and the transformer. To prevent environmental contamination by leaks or ruptures in the oil circulation conduits, secondary or sleeving conduits surround and protect the circulation conduits and additionally provide an independent leak flow conduit back to the filter cabinet dry sump. An accumulation of oil in the dry sump actuates a fluid sensor to transmit an alarm signal.

  • Patent number: 6335690
    Abstract: A fluid sensing system for monitoring a fluid parameter within a fluid container includes a fluid sensor and a fluid receiver. The fluid sensor is positioned at a first location and is operable to sense the fluid parameter. The fluid receiver is positioned at a second location remote from the first location and within proximity to the fluid sensor. The fluid receiver includes an amplifier having a feedback path. The amplifier is in a waiting non-oscillating mode when the fluid sensor is not electromagnetically coupled to the fluid receiver and in an active oscillating mode when the fluid sensor is electromagnetically coupled to the fluid receiver, such that feedback in the feedback path is one of either a substantially zero feedback and a negative feedback when the amplifier is a waiting non-oscillating mode and said feedback path is a positive feedback when said amplifier is in an active oscillating mode.

  • Patent number: 5986597
    Abstract: A fail-safe fluid transfer control apparatus has full redundancy in the response to various inputs such as overfill probe signals, ground detection signals, and the like. Independent microprocessor controllers independently evaluate the inputs and each output control signals to close a respective relay when the inputs indicate that fluid transfer may commence. The relays are arranged in series such that both must be closed for a fluid transfer to commence. The control signals from each controller include a static signal and an alternating signal, both of which must be properly output to close its respective relay. Each controller monitors the state of each relay, and discontinues its control signals if either relay appears to be malfunctioning. Each controller runs an different, independently written firmware program to process the detected inputs to prevent a common firmware error.
