Patent number: 10523117Abstract: A photovoltaic power system for supplying power to an electric grid is provided, in which a plurality of photovoltaic panels are each configured for generating a DC power signal. A plurality of DC-DC power converters connected to the photovoltaic panels are provided for converting the DC power signal into a deadband DC signal having a rectified sine waveform with reoccurring deadband periods, which reduces the risk of arcing during power transmission. An electric network interface is used to convert the deadband DC signal received from the plurality of DC-DC power converters into an AC power signal.Type: GrantFiled: November 7, 2017Date of Patent: December 31, 2019Assignee: Southwire Company, LLCInventors: Charles Hume, Brad Freeman, Dave Sykes, Aldo Della Sera

Patent number: 6796951Abstract: An anatomical brace for stabilizing and supporting a uniting pivoting joint such as a knee joint disposed between a first limb structure and a second limb structure. The brace includes first and second cuffs and a pivotable brace joint there between with two opposing pivoting assemblies. Each assembly includes forward and rearward arm members in tandem and a frame structure having a first end attached to the first cuff and a second end attached to the second cuff. Extending between the cuffs is an adjustable joint extension limiter for regulating pivotable distance of the cuffs in relation to each other. Spherical sockets movably positioned within the frame structure permit naturally-occurring multi-planar joint movement such that the brace here defined effectively limits pivotal extension distance, yet permits normal joint bendability with multi planar movability up to such limit, thereby stabilizing and supporting joint-controlled limb unions.Type: GrantFiled: February 2, 2001Date of Patent: September 28, 2004Assignee: Asterisk.Asterisk. LLCInventors: Brad Freeman, James Castillo

Patent number: 6793641Abstract: A brace for protecting a pivoting joint situated between a first and second limb structure. The brace includes upper and lower frame members linked by a joint member, with each frame member having a cuff for encompassing a portion of each limb structure. Brace retention is accomplished with respective upper and lower securement members each including a medial piece and a lateral piece each attached at respective outside edges thereof to an elastomeric central piece disposed there behind. Respective inside edges of the medial and lateral pieces have a tightening member for drawing the edges toward each other. The respective outside edges of the medial and lateral pieces are releasably attached to respectively adjacent frame and cuff sites with quick-release connectors releasable substantially without increased pressure on the limb structure. Such quick-connect and quick-disconnect operability provides proper brace placement without awkward, and potentially incorrect, brace orientation.Type: GrantFiled: February 4, 2002Date of Patent: September 21, 2004Assignee: Asterisk.Asterisk, LLCInventors: Brad Freeman, Danny Castillo, Ricardo Jimenez, Billy Frank, Dave Castillo, Mark Wilson

Patent number: 6461318Abstract: An exteriorly positionable anatomical brace for protecting a uniting pivoting joint disposed between a first limb structure and a second limb structure of a living being. The brace includes a first cuff partially encompassable about the first limb structure and a second cuff partially encompassable about the second limb structure with each cuff being a generally U-shape structure with two lateral arms. A respective quick-release cuff retainer secures each cuff on each limb, and includes opposing first and second limb wraps for positioning around the limb. At least one limb wrap has a proximal portion provided with at least one externally accessible releasable connector for attaching the limb wrap to the respective lateral arm, while both limb wraps have distal portions interfacedly connected with each other with a tightenable interfacing retainer member. A pivotable brace joint member connects the first and second cuffs and is situated adjacent the pivoting joint to be stabilized.Type: GrantFiled: January 29, 2001Date of Patent: October 8, 2002Inventors: Brad Freeman, Danny Castillo, Ricardo Jimenez, Billy Frank, Dave Castillo, Mark Wilson
