  • Patent number: 8284015
    Abstract: A smooth surface of a control device is achieved by positioning the actual control devices within a sealed housing and having the operator touchable knobs proximity connected to the control devices through the surface of the housing. In one embodiment, the proximity connection is a magnetic connection between the handle mechanism detachably positioned on the outside of the housing and traditional slider potentiometers mounted within the housing. In another embodiment, longitudinal proximity sensors within the housing are used to emulate the physical layout of the slider potentiometers and the movement of handle mechanisms outside the housing create the changing proximity under control of the operator. In all embodiments, the outside handle mechanism easily separates from the housing leaving a relatively smooth outer housing surface which can be easily sanitized. The removed handle mechanism allows for easy cleaning and sanitizing as well as for easy substitution.

  • Publication number: 20120242435
    Abstract: A micro-machined magnetic relay has a moveable cantilever comprising a soft magnetic material and having a first end and a second end. The cantilever has a rotational axis which is a flexure supported by a substrate. The cantilever has a first state and a second state. A first permanent magnet is disposed near the first end of the cantilever to force the cantilever in the first state. A second movable magnet causes changes of magnetic forces and torques on the cantilever. Therefore, the direction of a sum of torque on the cantilever is reversed. As a result, the cantilever flips from the first state to the second state. The relay can be used as a proximity sensor to detect the motion of an object associated with the second movable magnet.

  • Patent number: 8264309
    Abstract: A magnetic target is provided for use with a magnetic proximity switch. The magnetic target includes a cylindrical body tube having an open end that partially defines a bore. A stationary magnet is located within the bore opposite the open end, and a movable magnet is disposed within the bore between the stationary magnet and the open end. An adjusting member is received into the bore, and a contact surface of the adjusting member engages the movable magnet. When the adjusting member is axially displaced, the contact surface causes a corresponding displacement of the movable magnet relative to the stationary magnet, eventually causing the magnetic flux field of each magnet to expand in a radial direction away from the longitudinal axis of each magnet. The stationary magnet and the movable magnet may be either axially-magnetized samarium-cobalt magnets or axially-magnetized neodymium magnets.
