  • Patent number: 10577834
    Abstract: The disclosed computer-implemented method may include a magnetic insertable lock component with a magnet-sensing lock housing. By using a magnet within a pin and a magnetic field sensor within the lock housing, the apparatus may accurately detect the state of the lock. In some embodiments, the apparatus may determine the pin is inserted fully into the lock, the pin is inserted partially into the lock, the pin is not inserted in the lock, and/or that a foreign object that is not the pin is inserted into the lock. By using a magnet within the pin to track the state of the lock, the apparatus may improve both the user experience and the security of the lock. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 10504672
    Abstract: A knob switch device includes a knob portion and a control circuit portion. The control circuit portion is electrically connected to an encoder and at least one switching component. The knob portion includes a knob configured to control the encoder, and further includes a trigger mechanism configured to trigger the switching component. The knob drives the trigger mechanism to trigger the switching component by an axial movement. The knob transforms a change in a mechanical rotation angle into an electrical signal, and the functional mode of the intelligent closestool is switched by pressing or pulling the knob in the axial direction. In this way, the multiple functions of the intelligent closestool are flexibly controlled by using a single knob, and the knob switch device has a compact and small structure, thereby shortening the distance between a person and the intelligent closestool.

  • Patent number: 8847715
    Abstract: A permanent magnet is pivotally mounted in a top spacer layer of a switching device and rests on a flex arm created in an underlying flex circuit layer. The underside of the flex arm rests on a thin bar formed in a lower spacer layer beneath which lies a base layer including an electromagnet. Activation of the electromagnet causes rotation of the flex arm to thereby close and open electrical contacts formed respectively on the underside of the flex arm and on the top surface of the base layer.

  • Patent number: 8766751
    Abstract: Proximity switches are disclosed that preferably are provided in a hermetically sealed unit that can be used in harsh environments and under significant pressures, such as underwater and in nuclear power facilities, without having any parts that would require replacement or periodic maintenance. The proximity switches are preferably switches actuated by physical movement of a contact in response to changing magnetic forces. The switches are preferably disposed in a body tube optionally including a hermetic seal assembly to seal an open end of the body tube and/or a ferrule that prevents electrical wires attached to the switch inside the body tube from being pulled away from the switch. Further, the switches preferably maintain a contact pressure between electrical contacts sufficient to withstand acceleration seismic testing of 10 g with no contact discontinuity.

  • Patent number: 8760251
    Abstract: A stacked field emission system having an outer surface includes at least three field emission structure layers having a stacked relationship that defines a field characteristic of the outer surface. The mechanisms holds the at least three field emission structure layers such that a plurality of interface surfaces of the at least three field emission structure layers correspond to a plurality of interface boundaries between adjacent field emission structure layers. Each of the at least three field emission structure layers includes a plurality of field emission sources having positions, polarities, and field strengths in accordance with a spatial force function that corresponds to a relative alignment of the at least three field emission structures layers in the stacked relationship. A movement of at least one of the at least three field emission structures varies the field characteristics of the outer surface.
