Multiple Degree of Freedom Portable Rehabilitation System Having DC Motor-Based, Multi-Mode Actuator
Publication number: 20150290071Abstract: The Navigator is multiple degree of freedom neuro rehabilitation system. The Navigator simultaneously exercises both pronation and supination of the wrist (rotation) and flexion and extension of the fingers (grasp and release) for rehabilitation and monitoring of patients with motor control deficits due to a neurological ailment, such as stroke. In addition, the Navigator provides a visual, interactive environment for performing therapeutic exercises. The interactive environment provides motivation to the patient and can provide real-time feedback to the patient about the quality of the movements being performed.Type: ApplicationFiled: December 2, 2013Publication date: October 15, 2015Inventors: Patrick Joseph Murphy, Ray Adler, Katherine Bausemer, Joseph Gonsalves, Kevin Thompson, Qingchao Kong, Mark L.

Patent number: 9084314Abstract: The present disclosure relates to a programmable underwater lighting system for pools and spas. A plurality of underwater lights, each having a plurality of LEDs for producing light of various colors, a microprocessor for controlling the plurality of LEDs, and a memory in communication with the microprocessor containing one or more stored control programs, allow for the generation of various lighting effects in a pool or spa. A central controller is provided in communication with the plurality of underwater lights, and allows a user to define or select a desired lighting effect (such as a sequence, a fading effect, a “moving” color pattern, etc.) using a display and a keyboard. Optionally, a handheld remote control could be provided, in wireless communication with the central controller, for allowing a user to remotely control the plurality of lighting fixtures.Type: GrantFiled: November 28, 2007Date of Patent: July 14, 2015Assignee: Hayward Industries, Inc.Inventors: Gilbert Conover, Kevin L. Potucek, Lloyd Slonim, Carl L. Brunetti, Joseph Gonsalves, Paul Canavan

Publication number: 20130294115Abstract: A synchronous rectification circuit includes a transformer receiving an input voltage at a primary side and outputting an output voltage at a secondary side and a controller arranged and programmed to operate independently from the input and output voltages. The controller preferably outputs control signals to switching logic devices, the switching logic devices being arranged to output timing signals to drive individual synchronous rectifiers included in the secondary side of the transformer. The synchronous rectification circuit includes at least one logic gate which receives the control signals output from the controller and supplies clock signals to the switching logic devices, the clock signals being generated by the at least one logic gate based on the control signal and driving devices arranged to receive the timing signals from a respective one of the switching logic devices, the driving devices driving the synchronous rectifiers in accordance with the timing signals.Type: ApplicationFiled: March 1, 2012Publication date: November 7, 2013Applicant: MURATA MANUFACTURING CO., LTD.Inventor: Joseph Gonsalves

Patent number: 8299713Abstract: A method of accelerating charged particles using a laser pulse fired through a plasma channel contained in a capillary, wherein the plasma waveguide has deviations along its length that cause deviations in the plasma density contained therein, the deviations in plasma density acting to promote charged particle injection into a wake of a passing laser pulse. A radiation source based on a laser-driven plasma accelerator in a plasma waveguide in which the plasma waveguide and/or laser injection process is/are controlled so as to produce an undulating path for the laser pulse through the waveguide, the undulation exerting a periodic transverse force on charged particles being accelerated in the wake of the laser pulse, the resulting charged particle motion causing controlled emission of high frequency radiation pulses.Type: GrantFiled: September 11, 2007Date of Patent: October 30, 2012Assignee: Isis Innovation LimitedInventors: Simon Martin Hooker, Anthony Joseph Gonsalves, Dino Anthony Jaroszynski, Wim Pieter Leemans
