A device for monitoring the function of an engine is powered by heat from the engine or other sources other than a conventional, external direct electrical power supply, which may create sparks and/or be unavailable. The device monitors one or more of heat, vibration, or other parameters and can detect certain problems with engine function. The device is particularly suited for remote engine monitoring, and can store and/or display data concerning monitored engine characteristics, and/or directly or indirectly send such data to a location removed from the engine.

Systems and methods for sensing water device run time, transmitting this data via a network to a database which analyzes, records and reports the individual run times and the aggregate use over any given timeframe. Sensors used to measure device use time do not directly measure flow rate, and may sense device run time by sensing water flow, through electronic signals, vibration, etc. The sensors may be battery powered and transmit discrete data packets via radio frequency to powered node units. A system of node units communicates with a central internet gateway which uploads the data packets to a cloud-based database which organizes, analyzes, stores and reports the information. The system allocates the cost of water flowing through a common water meter to a plurality of individual units within a collection of geographically proximate units. The systems are useful in multi-unit buildings or complexes having stacked plumbing.

A self-charging sensor (SCS) adapted for use in a toilet or the like. The SCS includes a housing having a rechargeable battery; a turbine module having a multilevel impeller having offset wheels that are adapted to be driven by a fluid flow via an inlet port during an event, wherein a rotation of the impeller causes the turbine module to generate electricity that recharges the rechargeable battery; and a processing module that collects count data associated with the rotation during the event; and an attachment component adapted to seat the housing on an overflow tube.

A point of entry water treatment system is connected between a water supply and a plumbing system. The system includes a valve and a network communications module. The system is configured for receiving a signal from a remote sensor via the network communications module. The signal is indicative of a detected flow event. The controller is further configured for closing the valve either automatically in response to the signal from the remote sensor or in response to a signal received from a remote user interface device via the network communications module.

A leak detecting device for a fluid filled vessel including a housing, a solid shaft, an anchoring attachment, and a resilient member. The housing has a continuous perimeter edge sized to extend around an underwater surface, forms a hollow interior, and includes a first aperture formed through a wall of the housing and a second aperture formed through the wall of the housing. The solid shaft extends through the first aperture of the housing and has a first end on an interior side of the housing and a second end on an exterior side of the housing. The anchoring attachment is secured to the first end of the solid shaft. The resilient member is secured to the perimeter edge of the housing.

A gas-detecting apparatus, having a gas inlet and a gas outlet, for detecting a false alarm is disclosed. The gas-detecting apparatus comprises a control module, a sensor module, and an air chamber. In an example embodiment, the sensor module is electrically connected with the control module. The sensor module has a sensor inlet and a sensor outlet. The sensor inlet is fluidly coupled to the gas inlet of the gas-detecting apparatus. The air chamber has an air inlet and an air outlet, wherein the air inlet is fluidly coupled to the gas inlet of the gas-detecting apparatus and the air outlet is fluidly coupled to the gas outlet. The control module is configured to receive a first sensing signal for a first level of gas from the sensor module and determine whether magnitude of the first sensing signal is higher than a first threshold value. In an instance when the magnitude of the first sensing signal is higher than the first threshold value, the control module causes the air chamber to supply ambient air to the sensor module through the sensor inlet of the sensor module.

The present application generally relates to fluid flow detection apparatuses and methods for detecting a water leak in a pipe system of a building. A method may: determine that a low flow is present, if absolute values of temperature differences between ambient and pipe temperatures of respective samples of a first monitoring period are above a difference threshold; and perform a high flow test by estimating a temperature profile of water entering the pipe, based on identifying at least one temperature difference maximum of a second monitoring period, wherein each said difference maxima is a maximum temperature difference between ambient and pipe temperatures of a received sample, and determining that a high flow is present by detecting, based on the received pipe temperatures of the second monitoring period, if the pipe temperature is approaching the estimated water temperature profile.
