Patent number: 9531801Abstract: A software platform preferably delivered via the internet provides access to and from web-enabled devices with the purpose of delivering and providing software applications, hardware resources, reporting, monitoring, tracking, virtual and cloud computing augmentation, all through a cross-end point unified user-based interface. Resources can be connected dynamically to other resources through the platform and, depending upon the decision of the user and the security settings, resources of the end-point device can be provided to other members in the same network.Type: GrantFiled: August 6, 2012Date of Patent: December 27, 2016Assignee: Virtual Command, LLCInventors: Mark Cantrell, Chris Chapman, Robert Russo

Patent number: 8564327Abstract: A USB-based isolator system conveys USB signals between a pair of galvanically isolated circuit systems and supports controlled enumeration by a downstream device on upstream USB signal lines. The isolator system provides a multi-mode voltage regulator to support multiple voltage supply configurations. The isolator system further provides control systems for each of the isolated circuit systems and provides robust control in a variety of start up conditions. Additionally, the isolator system includes refresh timers and watchdog mechanisms to support persistent operation but manage possible communication errors that can arise between the isolated circuit systems.Type: GrantFiled: March 22, 2012Date of Patent: October 22, 2013Assignee: Analog Devices, Inc.Inventors: Eric Gaalaas, Mark Cantrell

Patent number: 4350252Abstract: A storage rack for displaying flat, rectangular articles such as record jackets along a wall surface. The rack is comprised of at least two elongated rack members mountable to a support in transverse alignment for receiving opposed side edges of the article. The rack members are grooved to receive the opposed article side edges. The openings are spaced outwardly of integral support surfaces at bottom ends of the grooves. These support surfaces bear the weight of the articles at corners thereof adjacent the opposed article side edges. An article can be removed from the rack simply by moving the article longitudinally clear of the support surfaces, shifting the article outwardly into alignment with the access opening and pulling the article longitudinally from between the rack members.Type: GrantFiled: July 10, 1980Date of Patent: September 21, 1982Inventors: Grant Hopkins, Mark Cantrell

Patent number: 4279429Abstract: A vehicle powered to move about on a front drive wheel and rearward supports, preferably a pair of wheels. The rear wheels are mounted to the frame by a steering control mechanism that facilitates pivotal steering movement of the rear wheels about two axes - a steering axis and a steering control axis. The steering control axis is coaxial with the rear wheels and is perpendicular to the steering axis. The angle of the steering axis may be varied about the steering control axis. Steering is accomplished by the rider shifting his weight from one side of the vehicle to the other. He may shift the steering axis to a position substantially parallel with the ground surface so the frame may be tilted like a bicycle in wide, sweeping high speed curves. The rear wheels then track behind the front wheels as the frame tilts about the steering axis. If the rider shifts the steering axis to a position nearly perpendicular to the ground, he may negotiate short radius, low speed turns.Type: GrantFiled: January 15, 1980Date of Patent: July 21, 1981Inventors: Grant Hopkins, Mark Cantrell
