  • Patent number: 8917175
    Abstract: The present invention relates to devices and methods for tracking movement in a marine environment. At least one tracking device that is adapted to be deployed on a surface of the water, wherein the tracking device is capable of moving along the same trajectory of a desired object. Data from the tracking devices are received by at least one satellite, transmitted to a database, and used to determine the forecasted trajectory of the desired object. All data collected from deployed tracking devices may be integrated into a spatial data repository for analysis and reporting using GIS and associated information technologies, thereby allowing for more accurate decision-making and asset deployment during a fluid spill or similar marine contamination event. The present invention also allows for the collection and modeling of accurate localized sea current data, which may assist with marine and coastal engineering works such as shoreline protection and port dredging.

  • Patent number: 8917576
    Abstract: Utilizing a sonar system to determine if a structural member of an underwater support structure that is supposed to be filled with air is instead flooded with water. The determination that a supposedly air filled structural member is instead flooded with water provides an indication that the structural member is cracked or damaged, making it easier to find damaged members and effect suitable repair. The sonar system is located a distance from the structural member so that it is spaced from the structural member.

    Abstract: A process measurement instrument adapted for wireless communication, comprising a measurement unit (7) arranged to determine a measurement value of a process variable, a memory (21) arranged to store a current measurement value of the process variable, a wireless communication unit (8), arranged to access the current measurement value and communicate the current measurement value over a wireless communication channel according to a protocol with intermittently active communication, and arbitration logic (22), in communication with the measurement unit and the wireless communication unit, and arranged to ensure that active periods of the measurement unit occur when the wireless communication is inactive. The measurement unit and communication unit are thus able to share information via the common memory, e.g. by sequential read/write access. This avoids the need for simultaneous activity.

  • Patent number: 8432291
    Abstract: A diagnostic system and method for a home appliance is provided. When the home appliance outputs product information as a sound signal, a service center remotely performs fault diagnosis of the home appliance by receiving the sound signal, detecting the product information from the sound signal, checking the state of the home appliance using diagnostic data included in the product information to determine whether the home appliance is out of order, diagnosing, when water supply malfunction including a water supply error or a water level sensor error has occurred, a cause of the water supply malfunction, and deriving a solution to the water supply malfunction. Upon deriving a diagnosis result through the fault diagnosis of the home appliance, the service center immediately notifies the user of the diagnosis result and may dispatch a service technician or may provide the user with a solution to allow the user to easily fix the fault without dispatching a service technician.

  • Patent number: 8412473
    Abstract: According to various embodiments disclosed herein, battery power may be conserved by reducing the number of transmissions made by a liquid level monitoring system. The efficiency of a liquid level monitoring system may also be improved by reducing or avoiding fuel outages and unnecessary replenishment. Certain embodiments may be configured according to a schedule for making measurements. The measurement may then be compared against one or more thresholds to determine whether to transmit the measurements. A variety of thresholds may be specified and utilized to determine when it is appropriate to transmit the measurements. Further, various embodiments may be configured to detect a change in a monitored condition. Upon the detection of a change in the monitored condition, a measurement may be made and compared to an established threshold for a tank.

  • 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: 8410944
    Abstract: A radiator detecting device of the present invention includes a radiator cap, a sensing unit, a circuit device, a warning device, and an adjusting means. One end of the sensing unit connects to the radiator cap, and another end extends toward a direction away from the radiator cap. The circuit device has a circuit board. The circuit board includes a control circuit for detecting a state of the sensing unit, and the sensing unit selectively makes the control circuit generate a suggestion signal. Once receiving the suggestion signal generated by the control circuit, the warning device generates a warning signal. The adjusting means is used for adjusting a length of the sensing unit received in the radiator. Said sensing unit can be moved with respect to the radiator between a first position and a second position. Thereby, the sensing unit can fit different depths of different radiators.

  • Patent number: 8395516
    Abstract: An air freshening device is provided for detecting water leaks and protecting surfaces from water damage due to leaks. The device includes: a tray, configured for being placed upon a surface located under a water pipe; a removable and replaceable liner placed upon the tray, the liner comprising a material configured for releasing an air freshening substance into air, and for increasing the release rate of the substance upon contact with water. The increase of the release rate of the substance leads to an intensifying of the scent of the substance in air, and indicates the presence of a leak from the water pipe. The tray prevents water leaking from the water pipe from touching the surface.
