Abstract: Modules, systems, and methods for monitoring environmental conditions, such as physical, electromagnetic, thermal, and/or chemical parameters within an environment, over extended periods of time with the use of one or more electromechanical sensing devices that include a sensing device and electronic circuitry for processing an output of the sensing device and generating a output of the module. The sensing device includes a microstructure, for example, a cantilevered beam, and at least one set of contacts configured for contact-mode operation with the microstructure in response to the microstructure deflecting toward or away from the contacts when exposed to the parameter of interest. The microstructure has a stack of layers of dissimilar materials, at least one of which has at least one property that changes as a result of curing of or absorption by the first material when exposed to the parameter.

Abstract: A rain sensor for use with an irrigation control system includes a position sensing element. A moisture absorptive element is supported for receiving rainfall. An actuating element is mechanically connected to the moisture absorptive element for movement adjacent the position sensing element as the moisture absorptive element expands and contracts to thereby induce a change in the position sensing element that can be used to generate an interrupt signal without any mechanical connection between the moisture absorptive element and the position sensing element.

Abstract: A valve assembly is operative for automatically shutting off both a water supply line and gas supply line to a gas-fired hot water vessel upon detection of water discharge, leak or overflow, from the water vessel. The valve assembly is connected in the water supply line and generally includes a valve body, a sliding valve member which is spring biased to a normally closed position, and a water softenable latch which maintains the valve member in an open position against the bias of the spring. The valve assembly is preferably positioned in a drip pan located under the water vessel such that water leaking from the water vessel will accumulate in the drip pan and submerge the valve assembly. Upon exposure to water accumulated in the drip pan, the water softenable latch at least partially softens and releases the valve member to move from its open position to its closed position to cut off water supply through the valve body. In connection with shutting off of the gas supply, a formation on the valve member engages a contact assembly as the valve member moves from the open to closed position. The contact assembly is wired into the power circuit of an electromagnetic valve actuator for a gas supply control valve. Engagement with the contact assembly temporarily disrupts the flow of power to the electromagnetic actuator causing the gas valve to be closed.

Abstract: A water-reacting absorbent cartridge for a release mechanism has multiple layers of water-absorbing paper material compressed into a solid, densified mass with a fraction of the original volume of the paper layers. The compacted cartridge may be wrapped in a tube of heat-shrink material with holes along its sides or may have adhesive interspersed between layers in order to keep the expansible paper layers together. Another water-reacting absorbent cartridge has multiple layers of a super absorbent material interspersed with layers of paper material compressed into a densified mass. The super absorbent material may be a powder dispersed in paper sheets, or in sheet form with paper layers interposed between. The expansible material may be contained in a jacket made of a water-permeable tightly-woven cotton fabric. Further, an oil-reacting absorbent cartridge is made of one or more layers of polyethylene molecular sponge compressed into a "hat shape" with a protruding portion on one side so that it can be seated in an oil detector unit with its expansion force concentrated through its central portion. One or more holes may be punched through the central portion to provide pathways for the oil and speed up the reaction time of the cartridge by a factor of ten.

Abstract: A simple, relatively low cost wall mountable humidistat that continuously indicates the water vapor content of gas, most preferably air. The humidistat has a conductivity probe with electrodes extending into two interconnected vials containing lithium chloride solution. Moisture is absorbed by the solution from the humid ambient air whereby a change of the volume of the solution results and the level of humidity can be determined.

Abstract: An alarm device for indicating the optimum humidity conditions for baling of hay is disclosed which comprises a humidity sensing device with its normally closed switch in circuit between an electrical power source and an audible alarm. The device is mounted at a location where it is responsive to the ambient atmospheric, i.e., outside, air humidity and is set to trigger the alarm when the air humidity reaches a value of at least about 55 percent. This indicates an optimum condition for baling since at this outside humidity the hay absorbs sufficient moisture that it is not defoliated when baled.

Abstract: A switch assembly activated by conductive liquids, typically water, and based upon use of a longitudinally slit resilient cylinder, carrying one of a pair of spaced, parallel rod-shaped electrodes at each side of the cylinder wall slit. A bolt passed transversely through the cylinder may be adjusted as to constrict or relax the resilient cylinder to thereby vary the spacing of the parallel electrode rods and the sensitivity characteristics of the switch. Moisture, for example, in the form of sprinkler produced water droplets, or the level of surface irrigation water, may bridge the electrode gap by impinging thereon and spreading longitudinally by surface tension effects. The resulting change in current may be utilized to trip a relay in an irrigation system supplying the activating water droplets, orwhere the switch is used in a level detector system-to provide a precise indicating signal that the monitored liquid level has become accessible to the electrode gap.
