  • Patent number: 10359747
    Abstract: A controlling device for indoor apparatus includes a detection module, a human machine interface (HMI) and a wireless transmission module. The controlling device accepts supervisor's setting for an indoor electronic apparatus via the HMI, detects the environment around the controlling device for generating a plurality of detection value via the detective module, and receives another detection value from a plurality of slave detection devices in same controlling system. The controlling device generates a control command based on setting parameter of the supervisor and the plurality of detection value, and transmits the generated control command to the indoor electronic apparatus via the wireless transmission module. The indoor electronic apparatus works based on the received control command, so the environment around the controlling system can satisfy supervisor's demand.

  • Patent number: 7342473
    Abstract: Methods, systems, and apparatuses are disclosed for magnetically-actuated relays/switches that suppress cantilever and/or hinge deformation. A permanent magnet produces a first magnetic field. A movable element is held between a pair of axially-aligned, rotationally flexible hinges. A space is present between the permanent magnet and the movable element. The space allows at least one end portion of the movable element to move toward the permanent magnet. A bar member is positioned in the space. A coil produces a second magnetic field to switch the moveable element between first and second stable states. At least the central portion of the movable element is magnetically attracted toward the permanent magnet. The bar member physically prevents the central portion of the movable element from flexing toward the permanent magnet due to the magnetic attraction.

  • Patent number: 7327211
    Abstract: A micro-machined magnetic latching switch is described. A moveable micro-machined cantilever has a magnetic material and a longitudinal axis. The cantilever has a conducting layer. A permanent magnet produces a first magnetic field, which induces a magnetization in the magnetic material. The magnetization is characterized by a magnetization vector pointing in a direction along the longitudinal axis of the cantilever. The first magnetic field is approximately perpendicular to longitudinal axis. A three-dimensional solenoid coil produces a second magnetic field to switch the cantilever between a first stable state and a second stable state. The temporary current is input to the three-dimensional solenoid coil, producing the second magnetic field such that a component of the second magnetic field parallel to the longitudinal axis changes direction of the magnetization vector. The cantilever is thereby caused to switch between the first stable state and the second stable state.

  • Patent number: 7312623
    Abstract: A method, system, and apparatus for testing one or more micro-magnetic switches on a wafer is described. A magnet is positioned adjacent to a first switch on the wafer. A probe card is positioned adjacent to the first switch. The probe card mounts a first set of probes and a second set of probes. The first set of probes interface with contact areas of a coil associated with the first switch. The second set of probes interface with conductors on the wafer associated with the cantilever of the first switch. A current source is electrically coupled to the first set of probes. The current source activates the coil of the first switch using the first set of probes to switch the cantilever from a first state to a second state. A switch state monitor is electrically coupled to the second set of probes. The switch state monitor determines whether the cantilever of the first switch is in the first state prior to the current source activating the coil of the first switch.

  • Patent number: 7253710
    Abstract: Systems and methods for actuating micro-magnetic latching switches in an array of micro-magnetic latching switches are described. The array of switches is defined by Y rows aligned with a first axis and X columns aligned with a second axis. Each switch in the array of switches is capable of being actuated by a coil. In an aspect, a row of coils is moved along the second axis to be positioned adjacent to a selected one of the Y rows of switches. A sufficient driving current is proved to a selected coil in the row of coils to actuate a selected switch in the selected one of the Y rows of switches. In another aspect, a plurality of first axis drive signals and a plurality of second axis drive signals are generated. These signals drive an array of coils, wherein each coil in the array of coils is positioned adjacent to a corresponding switch in the array of switches. Each first axis drive signal is coupled to coils in a corresponding column of coils in the array of coils.

  • Patent number: 7215229
    Abstract: Methods and systems of assembling and making laminated electro-mechanical system (LEMS) switches are described. A plurality of structural layers are formed that include at least two structural layers that each include a flexible member. The plurality of structural layers are stacked and aligned into a stack, to form at least one switch. Each structural layer in the stack is attached to an adjacent structural layer of the stack. When the formed switch is in an “on” state, the first flexible member is in contact with the second flexible member. When making contact with the second flexible member, the second flexible member flexes in response. In a further aspect, three flexible members may be present. When the switch is in an “on” state, the first flexible member is in contact with the second and third flexible members. When making contact with the second and third flexible members, the second and third flexible members flex in response.

  • Patent number: 7013088
    Abstract: A multichannel fiber optic module has an electromagnetic shield surrounding high frequency electrical components which is electrically and mechanically coupled to one or more guide rails near edges of a printed circuit board. The one or more guide rails of the printed circuit board include a ground trace on the top and/or bottom surfaces of the printed circuit board. The fiber optic module can be hot inserted into a module cage which has guide rail slots for mating with the guide rails of the fiber optic module. Through the guide rail slots, electromagnetic radiation from the fiber optic module is shunted to a ground plane to which the module cage is coupled on a host chassis ground. Standard singular fiber receptacles are used for the parallel data link modules to allow field cable termination.

  • Patent number: 6901221
    Abstract: Fiber optic transmitter and receiver electrical elements are implemented on separate vertical boards in fiber optic modules. An optical block implements lenses and reflecting surfaces to minimize manufacturing costs. The light receiver and light transmitter are mounted to receive and transmit non-orthogonal to the fiber axis to avoid optical cross talk. In one embodiment, receiver and transmitter are mounted at an angle greater than forty-five degrees with a perpendicular line to the reflective surfaces. In another embodiment, receiver and transmitter are mounted at an angle less than forty-five degrees with a perpendicular line to the reflective surfaces. The reflective surface for transmission may be a beam shaper to improve light beam uniformity and optical coupling and to avoid active alignment. The vertical boards have ground planes facing each other to minimize electrical cross talk. An optional shielded housing provides further shielding for reducing EMI.
