Patent number: 9620310Abstract: An accessory device for a circuit breaker. The device includes a housing having a top wall and a hinge portion. The device also includes a plunger arm that extends from the hinge portion to form a cantilever wherein the plunger arm includes a first surface and a sloped surface. The plunger arm is moveable between an initial position wherein the plunger arm does not activate the first and second switches located in the housing and a deflected position wherein the first and sloped surfaces simultaneously contact the first and second switches, respectively, thereby activating the first and second switches. The plunger arm also includes a plunger portion that is oriented transverse to the plunger arm. A mating surface is formed on the plunger portion that mates with a mating surface of a circuit breaker operating mechanism. Further, the housing, hinge portion, plunger arm, and plunger portion are integrally formed.Type: GrantFiled: September 5, 2014Date of Patent: April 11, 2017Assignee: SIEMENS INDUSTRY, INC.Inventors: Huy Nguyen, Mauricio Rodriguez

Patent number: 9281151Abstract: A shunt trip device for a circuit breaker having a trip bar for tripping the circuit breaker. The device includes a housing having a slot and a bottom wall having a pivot pocket. The device also includes a lever arm having a lever projection portion and a pivot portion. The pivot portion is located in the pivot pocket to enable rotation of the lever arm in the slot about a lever rotation axis between first and second positions. When the lever arm is in the second position, the lever projection portion moves the trip bar and trips the circuit breaker. The device further includes an actuation device that moves the lever arm to the second position. The pivot portion and pivot pocket form a configuration that increases a perpendicular distance between a force generated by the actuation device and the lever rotation axis.Type: GrantFiled: September 5, 2014Date of Patent: March 8, 2016Assignee: SIEMENS INDUSTRY, INC.Inventors: Huy Nguyen, Mauricio Rodriguez

Publication number: 20130225953Abstract: Functional near infrared spectroscopy (fNIRS) imaging is utilized to measure the influence of stimulation in real time. An fNIRS imaging device is integrated into a transcranial direct current stimulation (tDCS) stimulator by embedding fNIRS optodes on the tDCS stimulating electrodes. During tDCS stimulation, blood oxygenation levels are measured. For example, concentrations of oxyhemoglobin and deoxyhemoglobin are measured and compared to the concentrations of a baseline resting state to provide feedback on the efficacy of tDCS. Based on the feedback, a tDCS threshold and a dose-response relation for a particular subject can be quantified, and individualized stimulation parameters can be determined for the particular subject.Type: ApplicationFiled: February 25, 2011Publication date: August 29, 2013Applicants: FUNDACION HOSPITAL NACIONAL DE PARAPLEJICOS, DREXEL UNIVERSITYInventors: Antonio Oliviero, Guglielmo Foffani, Ivan Panyavin, Laura Mordillo-Mateos, Juan De Los Reyes Aguilar Lepe, Anna Merzagora, Kambiz Pourrezaei, Mauricio Rodriguez
