Abstract: A first input to a mobile device indicates a first navigation destination at a first level of specificity. The mobile device initiates navigation towards a first location corresponding to the first navigation destination. While navigation towards the first location corresponding to the first navigation destination is ongoing and before reaching the first location, in accordance with a determination that one or more first criteria are satisfied, the mobile device prompts for an input for determination a second location corresponding to a second navigation destination with a second level of specificity, the second level of specificity more specific than the first level of specificity. The mobile device receives a second input in response to the prompt. In accordance with a determination that the second input satisfies one or more second criteria, the mobile device initiates navigation towards the second location corresponding to the second navigation destination.

Abstract: Button functionalities for user interfaces, e.g., for use with a portable multifunction device, are disclosed. Exemplary button functionalities are described for an electronic device with a display, a rotatable and depressible input mechanism, and/or a button. Different device features may be accessed, depending on whether the rotatable and depressible input mechanism or the button is activated, and further depending on whether the activation represents a single press, a double press, or an extended press on the rotatable and depressible input mechanism or the button.

Abstract: A front independent suspension assembly for outdoor power equipment includes a first joint, a first wheel coupled to the joint, a first longitudinal arm pivotably coupled to the joint, a first lateral arm pivotably coupled to the joint, and a second lateral arm pivotably coupled to the joint. The second lateral suspension arranged substantially parallel to the first lateral suspension arm.

Abstract: A self-latching piezocomposite actuator includes a plurality of shape memory ceramic fibers. The actuator can be latched by applying an electrical field to the shape memory ceramic fibers. The actuator remains in a latched state/shape after the electrical field is no longer present. A reverse polarity electric field may be applied to reset the actuator to its unlatched state/shape. Applied electric fields may be utilized to provide a plurality of latch states between the latched and unlatched states of the actuator. The self-latching piezocomposite actuator can be used for active/adaptive airfoils having variable camber, trim tabs, active/deformable engine inlets, adaptive or adjustable vortex generators, active optical components such as mirrors that change shapes, and other morphing structures.

Abstract: Devices and methods for controlling magnetic anisotropy and orientation of magnetic single domain structures between stable states are provided based on piezoelectric thin films and patterned electrodes. By using patterned electrodes, piezoelectric strain is manipulated to achieve a highly localized biaxial strain in a piezoelectric substrate and rotate the magnetic anisotropy of magnetic materials. Reorientation of a magnetic single domain between different stable states is accomplished by pulsing voltage across pairs of electrodes. Since only a small region surrounding the electrodes is strained, the methods can be applied to arrays of indexed magnetic elements and to piezoelectric thin films clamped to silicon base substrates.

Abstract: A transducer for generating electrical energy from an expected force includes a single crystal ferroelectric material having a phase transition stress level. Mechanical stress is provided to this crystal at a level approaching the phase transition stress level, such that the expected external force will cause the phase transition. At least two electrodes are joined to the single crystal for receiving electrical energy created by the phase transition. The electrodes can be joined to conditioning and storage circuitry. In further embodiments, the phase transition is induced by an expected temperature change.

Abstract: A tethered flying toy includes a ring-like frame rotatable about an axis substantially perpendicular to the plane of the toy. The frame extends outwardly and upwardly from the plane of the toy away from the axis and has a downwardly extending skirt around the periphery thereof. The frame includes an inner circumferential edge defining an opening and the skirt includes an outer circumferential edge defining a border. The outer circumferential edge of the skirt extends in a plane parallel to but in upwardly offset relation from the plane of the inner circumferential edge. The frame also includes an S-shaped cross member interconnecting diametrically opposed portions of the frame. A tether line extends through an aperture formed in the cross member to a wrist strap which can be located around the arm of the thrower. An elastic band portion interconnects the wrist strap and the tether to provide elasticity for the tether during the flight of the toy.
