    摘要： This invention relates to a device for indicating liquid level in a liquid container by wirelessly communicating the angle of inclination of the device, and by inference the level of liquid in the container relative to a predetermined low level point. The same embodiment can be deployed in shallow or deep liquid containers as free-floating in the former, or tethered to a fixed point in the latter, to facilitate remote monitoring of the liquid level. The device can be easily moved to new locations without the use of tools or fixings with the location of the device updated on the remote user interface via GPS data transmitted with the sensor data.

    摘要： A self-cleaning sensor to determine a level of a liquid includes a tube with an interior coating and a plurality of horizontally aligned, electrically isolated, electrical contacts. The self-cleaning sensor includes the plurality of horizontally aligned, electrically isolated, electrical contacts that each terminate in an outer surface of an interior wall of the tube and are electrically connected to one or more electrical devices in a cap residing on the tube. Additionally, the self-cleaning sensor includes a float that is composed of a low density, low dielectric constant material buoyant in one or more liquids to be measured where each horizontal dimension of the float corresponds to each horizontal dimension of the tube.

    摘要： A pressure bladder comprising a substantially cylindrically shaped interior chamber is formed from a pliable, yet chemically resistant material, for example a fluoropolymer, such as FEP (fluorinated ethylene propylene). The interior chamber of the pressure bladder is hydraulically sealed at a distal end and is hydraulically coupled to a pressure sensor at a proximate end. Both the pressure bladder and pressure sensor are filled with an inert, non-reactive, stable measurement fluid. Optionally, a support mandrel with a second, smaller substantially cylindrically shaped interior chamber is hydraulically coupled between the pressure bladder and the pressure sensor and also filled with the measurement fluid. The pressure sensor is electrically coupled to electrical conductors, as is an optional thermistor. The conductors are received within a conductor protective tubing. The pressure sensor is disposed within a protective isolation tubing which is hydraulically coupled to the conductor protective tubing and to either the pressure bladder or support mandrel.

    摘要： An optical switch having a housing, and two optical fibers, that can be connected to a light source and a light detector. The optical switch includes a moveable member that moves from a first position to a second position. In the first position, an optical path is present through the two fibers guide using a reflection or emission of light from the glowable member. In the second position, there is no optical path present through the switch.

    摘要： A liquid, e.g., water, dispenser is disclosed which includes a programmed processor which controls many dispensing functions, including controlling liquid dispensing, controlling heating and cooling of liquid, monitoring uv sterilization, monitoring liquid in the drip tray, selecting and setting liquid temperature and displaying information relating to dispensing. The dispenser monitors uv sterilization by sensing uv light passing through the liquid to be dispensed. The dispenser prevents dispensing of the sterilized liquid if sterilization is not proceeding satisfactorily, and prevents dispensing of liquid altogether if the drip tray is full.

    摘要： A device for sensing the amount of oil in oil pans of internal combustion engines is disclosed. In the device, a bottom plunger is fixedly mounted onto the inside bottom of an oil pan, with a contact terminal being mounted onto the top surface of the bottom plunger. A top plunger is movably positioned above the bottom plunger, with a contact terminal being mounted onto the bottom surface of the top plunger. The two contact terminals are normally spaced apart from each other in the event of the amount of oil being not less than a preferred amount. However, the two terminals are selectively brought into contact with each other in the event of an oil shortage in the oil pan. The device also has a means for selectively generating an alarm signal under the control of an ECU in the event of the two terminals being brought into contact with each other.

    摘要： A proximity sensing apparatus comprising a capacitor and means for detecting the change in capacitance of the capacitor. The capacitor comprises two capacitive elements that are insulated from each other and are relatively movable. With at least one of the capacitive elements formed from an electrically conducting liquid. The capacitance detecting means operate as a switch in response to the change in capacitance producing a binary output. This output being combined with a series of other outputs from a series of such proximity sensors to form an apparatus to determine position of an object, particularly a liquid level.
