    Abstract: The method of making thin film humidity sensors uses thermal vapor deposition or drop casting techniques to fabricate nickel phthalocyanine-fullerene-based (NiPc-C60) quick response humidity sensors with negligible hysteresis. Prior to the deposition of aluminum electrodes, a glass substrate is cleaned by using acetone in an ultrasonic bath for 10 minutes. After cleaning, the substrate is washed with de-ionized water and then dried. A gap is created between two electrodes by masking the glass substrate with copper wire. This assembly is plasma-cleaned for 5 minutes in a thermal evaporator. Subsequently aluminum (Al) thin films are deposited on the assembly. Next, a mixture of equal parts NiPc-C60 is deposited onto the gap between the Al electrodes by thermal vapor deposition or by drop casting. A method of forming NiPc-graphene oxide (NiPc-GO) humidity sensors without using instrumentation drop casts an NiPc-GO suspension onto aluminum foil electrodes taped to a substrate.

  • Patent number: 9683977
    Abstract: An apparatus including a wireless transceiver of the gas monitoring processor that receives gas readings and a plurality of gas detectors at different locations within the predetermined geographical area that each periodically measure a current gas level at a respective location of the gas detector wherein for each gas reading of the gas detector, a processor of the gas detector compares the current gas level with a previously measured gas level, if the current gas level is different than the previous gas level, then the gas detector wirelessly transmits a message including the current gas level to the wireless transceiver of the gas monitoring processor and if the current gas level is unchanged from the previous gas level, then the gas detector transmits a beacon message to the wireless transceiver of the gas monitoring processor as an indication that the current gas level is unchanged from the previous gas level.

  • Patent number: 9649464
    Abstract: An oxygen concentrator may rely on a pressure swing adsorption process to produce an oxygen enriched gas stream from canisters filled with granules capable of separation of oxygen from an air stream. The adsorption process uses a cyclical pressurization and venting of the canisters to generate an oxygen enriched gas stream. Coupling an oxygen concentration sensor to the generated oxygen enriched gas stream may allow monitoring of the purity of the produced gas.

  • Patent number: 9144992
    Abstract: An object is to directly detect the emptiness of a solvent cartridge being mounted. An emptiness detection unit body includes a light transmissive tube which constitutes part of internal piping of a printer body, a light emitter, and a light receiver. The light transmissive tube is composed of a transparent tube, typically, a glass tube or a fluororesin (PFA) tube. The light emitter and the light receiver are arranged to face the light transmissive tube. The light transmissive tube is filled with a solvent supplied from the solvent cartridge. On the other hand, the light transmissive tube is filled with gas when the solvent cartridge is empty. The emptiness of the solvent cartridge is detected by a change in the amount of light received by the light receiver associated with the change in the light transmissive tube.

A second user located within a predetermined vicinity of the sensor device may be identified. The second user may be identified by the processor. The system may transmit an indication of the alarm data item received from the first user and the location of the sensor device in the work area to the second user. The transmission may be automatic on detection of the second user's location.

  • Patent number: 9035781
    Abstract: A gas appliance monitoring apparatus for automatically detecting and alerting to a “gas-out” condition of a gas appliance during operation, and/or for alerting to the presence of prolonged “gas-on” conditions of an appliance. The apparatus utilizes a highly sensitive low loss and low flow gas flow indicator with multiple flow sensors to monitor the gas flow characteristics of the appliance during use. A gas flow analyzer and alarm timing mechanism analyzes the gas flow characteristics and sounds an alarm at the appliance or wirelessly at a remote location upon detection of either of the above conditions. A biasing attraction magnet is incorporated in the fluid flow indicator to offset either the force of gravity or a return spring in low flow/low pressure applications. The piston is sealed for use in high pressure/low flow applications, and provided with a vent hole for residual gas bleed-off upon a stoppage of gas flow.
