Electronic components used to make a simple water detector: battery, resistor, transistor, water sensor and piezoelectric buzzer for audible alert A water detector is an electronic device that is designed to detect the presence of water for purposes such as to provide an alert in time to allow the prevention of water leakage.
In 1997, the company was purchased by Goodman Global (now part of Daikin North America), a heating-and-cooling manufacturer which sold it to Maytag (now part of Whirlpool) in 2002. [2] Goodman still owns Amana's air conditioner and furnace division, and Amana home appliances are now owned and manufactured by the Whirlpool Corporation. [3]
In October 2016, operations at the new facility ramped up and the first Goodman air conditioner and gas furnace units came off the line. [12] In 2017, the construction of the huge facility concluded to consolidate Goodman’s HVAC manufacturing, engineering, logistics, and customer support under one, very large 4.1 million square foot roof.

A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.
Powell v. The Home Depot USA, Inc., 663 F.3d 1221 (Fed. Cir. 2011), [1] was a decision by the United States Court of Appeals for the Federal Circuit on the issue of patent infringement on a "safe hands" device that Michael Powell, an independent contractor for Home Depot, created in response to injuries to the hands of associates using in-store radial arm saws.
A flame detector is a sensor designed to detect and respond to the presence of a flame or fire, allowing flame detection.Responses to a detected flame depend on the installation, but can include sounding an alarm, deactivating a fuel line (such as a propane or a natural gas line), and activating a fire suppression system.
The ultrasonic gas leak detector then produces an alarm when there is an ultrasonic deviation from the normal condition of background noise. Ultrasonic gas leak detectors cannot measure gas concentration, but the device is able to determine the leak rate of an escaping gas because the ultrasonic sound level depends on the gas pressure and size ...
In this case, the response speed was enhanced through the use of a very thin layer of Pd (20 nm). Moderate heating was presented as a solution to the response impairment observed in humid conditions. [10] Thin film sensor – A palladium thin film sensor is based on an opposing property that depends on the nanoscale structures within the thin ...
