Abstract: The tactile feedback actuator generally has a stopper, a damper, a hammer path between the stopper and the damper, a coil element fixedly mounted relative to the hammer path, and a magnetic hammer guidingly mounted for movement along the hammer path. The magnetic hammer has two opposite ends. Each end of the magnetic hammer has a corresponding permanent magnet. The two permanent magnets have opposing polarities. The magnetic hammer is electromagnetically engageable by a magnetic field emitted upon activation of the coil element so as to be longitudinally slid along the hammer path in any one of two opposite directions depending on a polarity of activation of the coil element. The stopper has a striking surface adapted for stopping the magnetic hammer, and the damper is adapted for decelerating the magnetic hammer as the magnetic hammer is longitudinally slid towards the damper.

Abstract: An array of ultrasonic transducers can be controlled to produce a steerable beam. Beam steering can be skewed by buffer delays in the distribution of a clock signal. The skew can be at least approximately linearized by distributing the clock signal in a diagonal fashion across an array of buffers corresponding to ultrasonic transducer controllers. Potential error in beam steering that can arise from clock skew can be corrected based on the linear tilt.

Abstract: A system and method for testing the quality of a conductor is disclosed. Specifically, a system of testing a conductor using voltage source generator that is capacitively-coupled through the conductor to voltage detector is disclosed. The voltage source generates a varying voltage signal which induces a voltage signal in the capacitively coupled microwire conductor. The voltage detector that is also capacitively-coupled to the conductor measures the induced voltage. Using the detected voltage signal, the voltage detector determines whether there are any conductive breaks in the conductor.

Abstract: A system and method for creating desired splay patterned microelectrodes is disclosed. A bundle of microwires is arranged into a desired splay pattern. This may be performed mechanically with a rigid frame, electronically by charging the microwires, or with some other technique. The microwires in the desired splay pattern are then heated to release internal tension. Upon completion of heating, the microwires are then slowly cooled such that the splayed microwires will retain the desired splay pattern. Insulation may then be added to the microwires if the microwires are not already insulated.

Abstract: A signal generator generates an electrical signal that is sent to an amplifier, which increases the power of the signal using power from a power source. The amplified signal is fed to a sender transducer to generate ultrasonic waves that can be focused and sent to a receiver. The receiver transducer converts the ultrasonic waves back into electrical energy and stores it in an energy storage device, such as a battery, or uses the electrical energy to power a device. In this way, a device can be remotely charged or powered without having to be tethered to an electrical outlet.

Each of the plurality of second processors can have a number of input lines less than the number of output lines of the first processor. Portions of the control signal can be sent through the output lines of the first processor to the plurality of second processors at substantially the same time.
