  • Patent number: 11136785
    Abstract: An elevator call box with internal, concealable latching mechanism comprises an internally disposed, cylindrical magnetic pin with a relatively low pull force that is slidably displaceable by an larger, external magnetic force supplied by a service technician. When the access door is closed, magnetic pin penetrates an orifice in a locking tab to lock the call box. The pin magnet is normally attracted to an adjacent, magnetically attractive clip snap-fitted to a latching block. The latch is externally disengaged via a stronger portable magnet carried by service personnel. The larger magnetic pull force of the portable magnet slidably displaces the smaller magnetic latch pin, freeing the locking tab to permit pivotal opening of the access door. Once the stronger magnet is moved away, the smaller magnetic pin, which is attracted magnetically to the clip, will return to it's rest position penetrating the locking tab and locking the control.

  • Patent number: 10210975
    Abstract: This application relates to a case for a portable electronic device. The case includes a magnetic boosting device, carried in a cover of the case. The magnetic boosting device includes a layer of magnetic elements including: (i) a primary magnetic element, and (ii) a secondary magnetic element. The primary magnetic element, characterized by having magnetic poles that are aligned perpendicular to the plane of the cover, provides a first magnetic field. The secondary magnetic element, characterized by having magnetic poles that are aligned parallel to the plane of the cover, provides a second magnetic field. The first magnetic field and the second magnetic field contribute to a resultant magnetic field that is asymmetrically disposed about the plane of the cover. The electronic device can include a sensor and a controller for placing the electronic device in a power saving mode when the cover is in a closed position.

  • Patent number: 9895969
    Abstract: A push-push latch includes a slider slidably disposed on a frame. A resilient element is to urge the slider toward an extended state. The slider or the frame defines a cam-track. A pin member is connected to the frame or the slider. The pin member selectably engages a closed course in the cam-track to cause the slider to alternate between a retracted state and the extended state in response to alternating application and removal of an actuating force on the slider. An interference member is on the frame to selectively prevent the pin member from engaging the closed course thereby locking the slider in the retracted state. A pivotable catch is rotatably on the slider to open in the extended state and to close in the retracted state. A shape memory alloy actuator selectively causes the interference member to selectively prevent the pin member from engaging the closed course.
