  • Patent number: 8850690
    Abstract: A method of manufacturing an armature for an electric motor, includes: placing a commutator and a lamination stack on an armature shaft, winding magnet wire in slots in the lamination stacks to form coils, attaching ends of the magnet wire to the commutator, and molding plastic around the magnet wire and around the shaft of the armature at ends of the lamination stack. A spinning inertia of the armature is adjusted by adjusting at least one of a mass of the plastic molded and a distribution of the plastic molded. Alternatively and/or additionally, at least one of a resonant frequency and critical speed of the armature is adjusted by adjusting at least one of a geometry of the plastic molded, the physical properties of the plastic and the mechanical properties of the plastic.

  • Publication number: 20140100687
    Abstract: A mode selector switch for a power tool that can have a source of a magnetic field and use a magnetoresistive component to produce an output signal that changes when the strength of the magnetic field changes. The power tool can have a microprocessor that changes an operational mode of the power tool based on a change of the output signal from the magnetoresistive component. The magnetoresistive component can be a Hall effect sensor and the power tool can be a nailer. The power tool can have a switching means which changes an operational mode based upon a change in the strength of the magnetic field upon a magnetoresistive component. A method of controlling a power tool, having a step of changing an operational mode of a power tool based upon identifying a change in output from a magnetoresistor.

  • Patent number: 8551545
    Abstract: A food package for segregating ingredients of a multi-component food product, such as the multiple components of a sandwich, the package comprising an outer container to house a first food component and at least one flexible envelope or barrier film layer that encloses at least one intermediate food component allowing for separation of the intermediate food component during extended periods of storage and prior to opening the product. A method for opening the package comprises applying a pulling force to an externally located protruding end portion of the envelope, such that the envelope peels apart and separates into ruptured layers that are pulled out of the food product and out of the outer container by the continual pulling force from the protruding end portion. Another method for opening comprises heating the container such that the barrier film layer ruptures upon heating, thus providing for components of the food product to combine.

  • Patent number: 8430351
    Abstract: Several small diameter short width rolls (124) of plastic film (108) are wound from a larger width and length of plastic web in a continuous manner. The disclosed apparatus slits the larger width plastic web into several narrower width plastic webs, positions the slit webs on a single large diameter winding drum (110) and then winds each narrower width web at a separate winding turret (112, 114). At each turret, the plastic web is rolled around a first mandrel until the roll achieves the desired size. Then, a second mandrel contacts, the plastic web and the plastic web is severed between the first mandrel and second mandrel and attached to a second mandrel to be rolled into a roll of desired length. The process is repeated at each turret such that the several plastic webs are simultaneously wound in a continuous fashion.

  • Patent number: 8406877
    Abstract: Systems and methods for steering one or more stimulation fields to a selected nerve target, thereby optimizing one or a combination of low stimulation thresholds, desired therapy outcomes, or a minimization of adverse stimulation side-effects. An array of electrodes disposed, at least in part, on two or more neural stimulation leads are used for steering the stimulation fields to the selected nerve target and are positioned adjacent the selected target. The stimulation may be titrated based on, among other things, a detected physiologic response to the applied stimulation.

  • Patent number: 8361145
    Abstract: An accommodating intraocular lens includes an optic portion a haptic portion and a backstop. The optic portion of the lens includes an actuator that deflects a lens element to alter the optical power of the lens responsive to forces applied to the haptic portion of the lens by contraction of the ciliary muscles. Forces applied to the haptic portion may result in fluid displacements from or to the haptic portion from the actuator. The backstop provides support to the haptic so that bulk translation of the haptic is prevented in response to the forces applied by the capsular sac.

  • Publication number: 20130015209
    Abstract: A shut-off system for a dispenser includes a pinch member that moves relative to a guide and which is normally biased against a flexible outlet tube that is disposed therebetween. The flexible outlet tube that carries material, such as soap, supplied from a pump to an outlet nozzle. The pump and the pinch member are in operative engagement with an actuator, such that when the actuator is not engaged, the pinch member closes the outlet tube to prevent residual material retained in the outlet tube from flowing or drooling out of the outlet nozzle. Correspondingly, when the actuator is engaged, the pump is compressed, and the pinch member is moved away from the outlet tube, allowing the material to be pumped through the outlet tube and dispensed from the outlet nozzle.
