  • Publication number: 20150129785
    Abstract: An electromagnetic valve includes a pressing member fixed farther towards an electromagnetic movable section side than a valve chamber in a nozzle. The pressing member is fixed to a plunger farther towards the side where the plunger is pressed by the pressing member than a position where the pressing member is fixed to the nozzle. Thus, a magnetic circuit defined by magnetic flux that is generated from a magnet is prevented from being located at a portion not related to an attractive force between a core and the plunger such that it is possible to effectively utilize the magnetic flux as an attractive force between the core and the plunger.

  • Publication number: 20150115183
    Abstract: A system for adjusting water in a domestic water diffuser, in particular for opening and closing water in a shower or bathroom or kitchen sink and for adjusting the flow rate, is described. The system comprises a shutter with at least one metal part slidable inside a cylindrical chamber with a diameter substantially equal to the diameter of the shutter; the system also comprises a pushbutton comprising a magnet; the pushbutton is configured to be operated by means of a finger to mechanically displace the shutter by means of the magnet along an axis of the cylindrical chamber, into two different positions, corresponding to opening of the flow or closing of the flow of water from a diffuser, the pushbutton being also rotatable about the axis, to vary the open position of the shutter along the axis and a corresponding flowrate.

  • Patent number: 8985288
    Abstract: A valve for a magnetorheological fluid is formed with a duct through which the magnetorheological fluid can flow and which can be exposed to a variable magnetic field such that the flow resistance of the duct can be set using the magnetic field in the duct. The magnetic field can be lastingly generated using a magnet device that is made at least in part of magnetically hard material. The magnetization of the magnet device can be lastingly modified by a magnetic pulse of a magnetic field generation device in order to lastingly change the magnetic field in the duct and thus the flow resistance of the duct. A valve of the invention requires energy only to change settings while a specific setting can be lastingly maintained without supplying energy.

  • Publication number: 20150024377
    Abstract: The present invention, in part, relates to an apparatus having a single-use, normally-closed fluidic valve that is initially maintained in the closed position by a valve element bonded to an adhesive coating. The valve is opened using a magnetic force. The valve element includes a magnetic material or metal. In some examples, the valve is opened by bringing a magnet in proximity to the valve element to provide a magnetic force that delaminates the valve element from the adhesive coating. In particular, the apparatus can be useful for on-chip amplification and/or detection of various targets, including biological targets and any amplifiable targets. Such apparatuses and methods are useful for in-field or real-time detection of targets, especially in limited resource settings.

  • Patent number: 8932047
    Abstract: A propellant flow actuated piezoelectric igniter device using one or more hammer balls retained by one or more magnets, or other retaining method, until sufficient fluid pressure is achieved to release and accelerate the hammer ball, such that it impacts a piezoelectric crystal to produce an ignition spark. Certain preferred embodiments provide a means for repetitively capturing and releasing the hammer ball after it impacts one or more piezoelectric crystals, thereby oscillating and producing multiple, repetitive ignition sparks. Furthermore, an embodiment is presented for which oscillation of the hammer ball and repetitive impact to the piezoelectric crystal is maintained without the need for a magnet or other retaining mechanism to achieve this oscillating impact process.
