  • Publication number: 20140261749
    Abstract: A touch-free faucet provides control over flow and/or temperature by detecting object presence in one or more detection zones. In one embodiment, the faucet provides for continuous-flow water flow wherein the spout of the faucet pours water for a period of time regardless of whether an object is detected in a detection zone, such as the sink, during that time. The faucet may initiate continuous-flow based on the detection of an object in another detection zone, and may cause continuous-flow operation for a determined period of time based on the amount of substantially uninterrupted time during which an object is detected in a detection zone associated with initiating continuous-flow mode. Furthermore, the faucet may provide for user-programmable sensitivity affecting the amount of continuous-flow time that is determined based on the amount of time that the faucet detects object in the continuous-flow mode detection zone.

  • Publication number: 20140261694
    Abstract: A power operated valve for controlling fluid flow is provided with a fail-safe device responsive to failure of the power supply to the valve to shut-off fluid flow. A valve member is coupled to linear actuator for movement towards and away from a closed position for controlling fluid flow through the valve. The linear actuator is held in a control position by the fail-safe device for normal operation of the valve with the power supply on. The fail-safe device responds to failure of the power supply to release the linear actuator. When the linear actuator is released, energy stored n a spring while the linear actuator was held in the control position is released and biases the linear actuator away from the control position causing the valve member to move to the closed position to shut-off fluid flow.

  • Publication number: 20140238493
    Abstract: A gas shut-off valve assembly designed to automatically close gas flow in a gas conduit in response to a seismic vibration comprises a trigger mechanism disposed in a trigger mechanism housing, a springless sealing mechanism disposed in a valve housing, a latching mechanism configured to engage the springless sealing mechanism to keep the gas conduit open, and a pressure release valve. Upon sensing a seismic vibration, the trigger mechanism disengages the springless sealing mechanism from the latching mechanism. Simultaneously, the springless sealing mechanism swings down and rotates around an axis by gravitational force to close off gas flow in the conduit. To reopen gas flow, the pressure release valve is actuated to relieve accumulated gas pressure inside the valve housing and the springless sealing mechanism is manually reset to its original open position.

  • Publication number: 20140224350
    Abstract: The present invention detects the presence of occupancy or activity in one or more locations of a building and remotely takes action to shut off the flow of water by keeping the main shutoff valve to the building closed when no activity or occupancy has been detected for a predetermined amount of time and opening this valve when activity has been sensed. Motion sensors are placed throughout the building in areas commonly traveled during occupancy/activity. The system is designed such that motion sensors have a means to communicate with a motorized water valve each time motion is sensed to control the opening and closing of the water valve. The means of communication between the one or more motion sensors and the motorized water valve may be a wireless signal such as a radio signal generator which transmits a radio signal to a receiver integrated with the motorized water valve.

  • Publication number: 20090212165
    Abstract: Passive removal of suction air for producing a laminar flow, and associated systems and methods are disclosed. One such method includes forming a laminar flow region over an external surface of an aircraft by drawing air through the external surface and into a plenum. The method can further include passively directing the air from the plenum overboard the aircraft. For example, the air can be passively directed to a region external to the aircraft having a static pressure lower than a static pressure in the plenum, as a result of the motion of the aircraft. Flows from different sections of the external surface can be combined in a common plenum, and the corresponding massflow rates can be controlled by the local porosity of the external surface.

  • Patent number: 7066192
    Abstract: The invention is a valve shut off device that is easy to install and remove. The valve shut off device has at least one sensor, a receiver a set of interchangeable adapters, and a motor unit. The motor unit is attached to a valve handle by an adapter, and the sensor can communicate to activate the motor. When the sensor detects a leaking substance, the motor unit is activated and turns the valve handle to the “off” position. The adapters allow easy installation and removal of the valve shut off device. Additionally, the adapters accommodate a variety of valves making the system universal. Among other things, the valve shut off device allows a property owner to be absent from his or her property without the risk of a leak causing extensive damage.

  • Patent number: 6997201
    Abstract: A wastewater control system for use with a sewer service line conducting a flow of wastewater from a building to a sewer main. A flow control device is installed in the sewer service line; and an actuator, in electrical communication with the sensor, is connected to the flow control device. The actuator in response to an output signal from a hydrologic sensor causes the flow control device to block the flow of wastewater to the sewer main and detain the wastewater in the sewer service line.

  • Patent number: 6935847
    Abstract: A pump assembly for a penile implant is provided having a mechanism which prevents spontaneous inflation of the cylinders implanted within the user. The preventative mechanism uses overpressure generated by the reservoir during unintentional compression to effectively seal the pump assembly from unintended fluid flow. The prevention mechanism itself creates all necessary forces to prevent the undesired fluid flow to the cylinders. This is accomplished by incorporating appropriate mechanisms within the pump itself.

  • Patent number: 6701951
    Abstract: A device and method to implement the device, to automatically adjust a single valve or a plurality of valves including turning the valve(s) on and off. The device includes a motor drive assembly, a mounting method, and a control method. Each component is discrete. The three components can be combined easily. The motor drive and control components can be mounted and connected to a valve that is currently connected to pipes. Thus one application of this invention is to provide a method to convert a manual valve to an automatic valve. The control method can operate as a means to turn the valve on and off using a manually operated switch or can be automatically controlled in response to an external stimulus. The invention has many applications including protecting real property from loss due to water damage, and against vandalism in cases where valves can be controlled by unauthorized people.

  • Patent number: 6662821
    Abstract: The invention is system and method for detecting a leak and operating an existing valve in response to the detected leak. In this regard, a receiving unit may be installed on an existing shutoff valve. The valve may control the flow of a fluid into a site. A transmitting unit may be installed in the vicinity of an appliance receiving the fluid. The transmitting unit may include a detector capable of detecting the fluid. In response to the detector detecting the fluid, the transmitting unit may transmit a signal including a unique 32 bit code. A receiver within the receiving unit may be capable of receiving the signal. Additionally, a PIC microprocessor within the receiving unit may be configured to receive the signal from the receiver and determine if the signal contains the code. In response to determining the signal contains the code, the PIC may control a motor to operate (e.g., turn off) the valve. The motor may be configured for attachment to the valve via a coupler.

  • Patent number: 6311897
    Abstract: A passive pulse generator can be connected to a line in order to activate a safety fitting in a nuclear power plant. The line can be closed by a closure element. In the event of a temperature change in the vicinity of the pulse generator, the closure element is actuated solely as a result of a thermal volume change of an actuating element, so that the line is released. The pulse generator therefore activates the fitting passively, without additional control pulses. A method for activating a fitting with a passive pulse generator is also provided.
