  • Publication number: 20190352937
    Abstract: An exemplary exit device includes a pushbar assembly, a remote latching assembly, and a coordination mechanism. The pushbar assembly includes a latch control assembly, and the coordination mechanism biases the latch control assembly toward its actuated state. The remote latching assembly includes first and second latch mechanisms, and the latch control assembly is operable to actuate the latch mechanisms. Each of the latch mechanisms at least selectively urges the latch control assembly toward its deactuated state such that the remote latching assembly exerts a variable deactuating force on the latch control assembly. The coordination mechanism selectively retains the latch control assembly in its actuated state, thereby selectively retaining at least one of the latch mechanisms in a corresponding actuated state. When the deactuating force exceeds a threshold force value, the latch control assembly and the latch mechanisms return to the deactuated states thereof.

  • Publication number: 20150336653
    Abstract: An air pumping device for the buoyancy control of a lighter than air craft is presented. The pumping device integrates within a single housing a centrifugal compressor and an axial gap, ironless core, electric motor. All of the rotating components of the compressor and motor are mounted on a single common shaft. The air pumping device includes a valve arrangement which allows for both forward and reverse airflow though the compressor portion of the device. The motor portion of the device features a stator coil and power, communications and sensor electronics, all integrated on a single common printed circuit board. The air pumping device exhibits exceptionally high operating efficiency and power density, which are highly desirable for lighter than air craft applications.

  • Patent number: 8637771
    Abstract: The disclosed invention describes a motor/generator coil produced using rectangular electric current conductors of any thickness and width. A unique joint between the up and down segments of the coil turn enables an improved conductor packing ratio and geometrical orientation that minimizes the effect of eddy currents. The resulting coil produces higher power than typical wire wound motors but is lighter weight and physically smaller in size. In addition, the coil can be free-standing, and is capable of slotless and/or ironless core device configuration.

  • Publication number: 20040174082
    Abstract: An electromotive induction device such as a motor having a stator that includes multiple cylindrical, concentrically mounted coils. The rotor includes multiple cylindrical, concentrically disposed magnets. The multiple coils of the stator are mounted on a stationary mounting plate. The concentric magnets of the rotor are affixed to a rotatably mounted shaft. The multiple coil stator is applicable to both brushed and brushless motors. The interleaved configuration of the multiple rotor magnets and the multiple coils of the stator increases the area of flux interaction between the rotor and stator and the power output of the motor. The electromotive induction device has a stator assembly and a rotor assembly rotatably attached to the stator assembly. The rotor assembly includes a circular rotor mounting plate having an axial drive shaft affixed thereto.

  • Publication number: 20030080645
    Abstract: An induction coil suitable for use either as a rotor or a stator in electromotive devices such as an electric motor, an alternator or a generator. The induction coil is made by stamping, etching or machining slots in plural metallic sheets. The metal between the slots on each slotted sheet constitute a plurality of substantially parallel electrical conductors. In a preferred embodiment of the induction coil, the individual slotted sheets are stacked to include two or more sheets, with the conductors of the top sheet substantially filling the slots in the bottom sheet, then rolled into a first cylindrical member. The process is repeated with a second stack of slotted sheets to form a second cylindrical member having a different diameter than the first cylindrical member. The first and second cylindrical members are coaxially assembled in axial alignment to form an assembled cylindrical member.

  • Patent number: 6111329
    Abstract: An armature for an electric motor is constructed from a pair of precision machined copper plates cut in a pattern to produce a series of axially extending surface conductive bands with each band separated from the other by an insulated cutout. The precision machined plates are rolled to form two telescoping, hollow cylinders with each cylinder having a pattern of conductive bands representing a half-electric circuit. The outer surface of the inner cylinder is wrapped with several layers of fiberglass strands for structural stability and insulation. The fiberglass wrapped inner cylinder is telescoped inside the outer cylinder. The outer surface of the telescoped structure is also wrapped with several layers of fiberglass strands for structural stability. The conductive bands from the outer cylinder being the near mirror image of the conductive bands of the inner cylinder are helically coupled to form a complete electrical circuit.

  • Patent number: 5953338
    Abstract: A system comprises a system control module and a plurality of interconnected asynchronous transfer mode switches the interconnected asynchronous transfer mode switches are interconnected with one another via at least one physical interface to form a network. The network is used to transfer various types of information. Each asynchronous transfer mode switch has a connection admission control module to determine whether a virtual connection, such a virtual path, virtual channel, or grouping of virtual paths, can be connected through that particular asynchronous transfer mode switch. The virtual connection is formed from one asynchronous transfer mode switch to at least one other asynchronous transfer mode switch via a link of the at least one physical interface. The system control module connects to at least one asynchronous transfer mode switch and determines whether the virtual connection can be created in the network.

  • Patent number: 5698866
    Abstract: A light delivery device including an interchangeable handpiece and a semiconductor light source module adapted to releasably attach to the handpiece. The light source module includes a two-dimensional array of light emitting diodes (LED's) disposed on a surface of a fluid-cooled electrically conductive support plate. The device is adapted for uniformly illuminating a tissue surface with phototherapeutic light. The phototherapeutic light is produced by an array of over-driven LED's mounted on the surface of the heat-sinked support. The semiconductor light source employs a multi-layer construction wherein electrically conductive layers are thermally isolated from each other. The device is rugged, inexpensive and can produce high optical power while operating at a temperature well below the temperature at which device failure occurs. The light source module is adapted to be releasably connected to an interchangeable LED handpiece which provides power to the LED's and conducts a coolant fluid.

  • Patent number: 4571243
    Abstract: System for stereotaxic lateral extradural disc puncture has a frame fitting over the patient which provides for proper location of the cannula of the needle. The frame has a pair of right-angle members. A lower bridge frame extends horizontally and is clipped to the vertical legs of the right angle members by magnetic clips. A bridge clip fits onto the lower bridge frame and is longitudinally slidable thereon. The stem of the cannula guide slides vertically in the bridge clip. A half-channel on the top of the stem comprises the cannula guide and a bead chain fixed near the half-channel insures that the stem is vertical. Forward and rear heading guide supports are magnetically attached to the horizontal legs of the right-angle members. These supports hold magnetic strips by which a transverse disc overlay strip is held in place. A second bead chain depends from the forward end of the disc overlay strip to locate the proper alignment of the point of the cannula.
