  • Patent number: 9622317
    Abstract: The present invention relates to an LED retrofit lamp (700) adapted for operation with an alternating current. The LED lamp comprises an LED unit (740), a mains current line, first and second switching devices (710, 720) (e.g., first and second relays), and a control unit (730). The control unit (730) detects an ignition voltage on the mains current line. In response to detecting the ignition voltage on the mains current line, the control unit (730) sets the first and second switching devices (710, 720) to a conducting state such that the LED unit (740) is connected to power. By using the first and second switching devices (710, 720), safety of the LED lamp (700) is improved, in particular when installing the lamp (700) into a fixture designed for fluorescent lamps.

  • Patent number: 9569942
    Abstract: Systems, devices, and methods are disclosed for securing a theft-susceptible movable object at a selected location. A security system is positioned at a selected location for protection of a theft-susceptible movable object. The security system includes a magnetic field source adapted to generate a magnetic field that is positionally-associated with a movable object. A monitoring device includes a magnetic sensor and is adapted for placement proximate to the selected location. The monitoring device is adapted to take one or more measurements of the magnetic field and to detect alteration in the measurements caused by movement of the magnetic field source relative to the monitoring device when the movable object is moved from the selected location. Upon detecting the alteration in the measurements of the magnetic field, the monitoring device is adapted to output an electronic warning signal indicating that the movable object has moved from the selected location.

    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: 8264308
    Abstract: A magnet is affixed to a shaft or other pivoting or rotating member of a switch mechanism, on the axis of rotation. The radial position of the resulting magnetic field is monitored. A change in the magnetic field radial position, optionally in excess of a threshold, indicates the onset of switch actuation, prior to operative actuation of the switch mechanism. The radial position of the magnetic field is sensed by a magnetic rotary encoder. The detection of switch actuation onset may be used to remove current from a circuit prior to operative switch actuation. Because the magnet is rigidly affixed to the shaft, there is no lost motion. Because the shaft position and encoder are magnetically coupled, the detection mechanism contains no moving parts and no mechanical linkage or coupling, and its performance does not degrade due to shock, thermal effects, vibration, or wear.

  • Patent number: 7999644
    Abstract: A central magnet of a plurality of magnets arranged to be different in polarities is detected by two hall ICs; therefore, reduction in size can be achieved by reducing the number of the magnets; and at the same time, the number of the hall ICs can be maintained and the reliability can be secured, as compared with a configuration in which the magnets and the hall ICs individually respond in one to one correspondence.

  • Patent number: 7948378
    Abstract: A non-defeatable magnetically actuatable switch device is shown and described for restricting access to industrial controls. The non-contact switch device employs one or more non-contact access switches, and an access key removably disposed in close proximity to each access switch. Removal or installation of an access key alters the electrical state of a corresponding access switch. A connected control unit determines a mode of operation, or grants permissions, based on the combination of access keys that are present or absent from the device. A lockable or sealable cover is provided over the access keys to limit unauthorized access. A tamper detection switch is also provided for the sole purpose of identifying foreign magnetic sources in the vicinity of the access switches to ensure that the device is non-defeatable.

  • Patent number: 7932796
    Abstract: A movable contact which is positioned inside a sealing case is moved by a magnetic shunt body which moves outside the sealing case. The movement of the movable contact by the movement of the magnetic shunt body is caused by a change of magnetic force of a magnet through a pair of yokes. The magnetic shunt body is assembled to a moving member, and elastically moves around the moving member resisting a first spring.

  • Patent number: 7924124
    Abstract: Electrical switching device, especially a high-frequency switching device, with at least one oblong electrical switching element, which is arranged with one contact end between two fixed-contact elements spaced a transverse distance from one another and can be moved by two adjustment elements forming a transverse movement drive transversely to a longitudinal direction optionally towards the one or the other fixed-contact element. The adjustment elements are disposed laterally alongside the switching element and can be moved transversely to and from the switching element. In order to improve the transverse movement drive for the switching element, the switching element-comprises magnetic material, wherein the adjustment elements are formed by magnets.

  • Patent number: 7782163
    Abstract: A set is disclosed with a position sensor and an exciter part. The position sensor has three reed contacts which are pointed parallel to one another in a triangle arrangement next to one another, of which the first two are used for doubled detection of the exciter magnetic field. The third reed contact is used to generate an error signal when the sensor is activated by means of an outside magnetic field. The exciter part has three permanent magnets which are arranged in a triangle arrangement which corresponds to the triangle arrangement of the reed contacts, with pole axes aligned parallel to one another. Of them, the first two magnets are pointed in the same direction and are located at a first distance to one another. The third magnet is polarized in the direction opposite the first two. This results in that only the two make contacts can be activated by the two bar magnets which are pointed in the same direction. Conversely, all three reed contacts are activated each by an outside magnetic field.
