Publication number: 20190186931Abstract: Example implementations may relate to sun-aware vehicle routing. In particular, a computing system of a vehicle may determine an expected position of the sun relative to a geographic area. Based on the expected position, the computing system may make a determination that travel of the vehicle through certain location(s) within the geographic area is expected to result in the sun being proximate to an object within a field of view of the vehicle's image capture device. Responsively, the computing system may generate a route for the vehicle in the geographic area based at least on the route avoiding travel of the vehicle through these certain location(s), and may then operate the vehicle to travel in accordance with the generated route. Ultimately, this may help reduce or prevent situations where quality of image(s) degrades due to sunlight, which may allow for use of these image(s) as basis for operating the vehicle.Type: ApplicationFiled: December 14, 2017Publication date: June 20, 2019Inventors: Jeremy Dittmer, Andreas Wendel

Publication number: 20190188502Abstract: Example implementations may relate to use of a light-control feature to control extent of light encountered by an image capture device of a self-driving vehicle. In particular, a computing system of the vehicle may make a determination that quality of image data generated by an image capture device is or is expected to be lower than a threshold quality due to external light encountered or expected to be encountered by the image capture device. In response to the determination, the computing system may make an adjustment to the light-control feature to control the extent of external light encountered or expected to be encountered by the image capture device. This adjustment may ultimately help improve quality of image data generated by the image capture device. As such, the computing system may operate the vehicle based at least on image data generated by the image capture device.Type: ApplicationFiled: December 14, 2017Publication date: June 20, 2019Inventors: Brendan Hermalyn, Andreas Wendel, Jeremy Dittmer

Patent number: 9883957Abstract: A luminal prosthesis comprises a plurality of radially expandable prosthetic stent segments arranged axially. Two or more of the prosthetic stent segments are separable upon expansion from the remaining prosthetic stent segments and a coupling structure connects at least some of the adjacent prosthetic stent segments to each other. The coupling structure permits a first group of the adjacent prosthetic stent segments to separate from a second group of the prosthetic stent segments upon differential radial expansion of the first group relative to the second group and the coupling structure maintains or forms an attachment between the adjacent prosthetic stent segments in the first group which have been expanded together. A delivery system and methods for deploying the multiple coupled prosthetic stent segments are also disclosed.Type: GrantFiled: February 18, 2014Date of Patent: February 6, 2018Assignee: J.W.

Publication number: 20120152309Abstract: Methods and apparatus are described for a concentrated photovoltaic system. A method of creating a paddle structure with a set of solar receivers that are aligned within and mechanically secured in place in each module contained in a paddle structure. Each solar receiver is assembled and aligned, where the assembly of the solar receiver establishes the alignment of the secondary optic to the photovoltaic solar cell. The assembly of a module with its set of solar receivers establishes the alignment in three dimensions the solar receivers with each other. Individual parts making up the receiver are 1) shaped, 2) sized, 3) keyed, 4) pinned and 5) any combination of these to fit together in only one way so that all of the solar receivers containing the photovoltaic solar cell maintain their alignment when installed in a given CPV module.Type: ApplicationFiled: September 8, 2011Publication date: June 21, 2012Applicant: GREENVOLTS, INCInventors: Wayne Miller, Victor Ocegueda, Jeremy Dittmer, Roger Sinsheimer, Mike Prucha

Publication number: 20100213761Abstract: The present invention is directed to an apparatus and method for improving the power output of a solar energy system. A field level inverter controller is described that may improve the power output of individual solar energy systems in a field of solar energy systems by controlling the inverter voltage applied to strings of solar energy units in a solar energy system connected in parallel to an inverter. An inverter load voltage for an improved power output may be calculated or derived empirically. An algorithm stored in the controller may calculate an improved load voltage for the inverters based on factors such as string geometry, solar movement and shade patterns generated by surrounding structures. Improved power output may be empirically determined by the field level inverter controller when the inverter controller directs an inverter to sweep a range of voltage values until a maximum output is detected.Type: ApplicationFiled: February 25, 2009Publication date: August 26, 2010Applicant: SOLFOCUS, INC.Inventors: Mark McDonald, Jeremy Dittmer

Publication number: 20090026279Abstract: The present invention provides an environmental control system for controlling moisture in a solar energy collector. The environmental control system facilitates the flow of air within and through the solar energy collector by using and enhancing a thermal gradient within the solar energy collector caused by exposure to sunlight. Two or more orifices are located in an enclosed solar energy system to permit air to enter, circulate and remove moisture from the system. The position of the two or more orifices and a thermal gradient generated by the solar energy collector facilitates this process.Type: ApplicationFiled: October 3, 2008Publication date: January 29, 2009Applicant: SOLFOCUS, INC.Inventors: Jeremy Dittmer, Marc Finot, Mark Spencer

Publication number: 20070219613Abstract: Apparatus and methods for interlocking stent segments which provide for a secure engagement between the expanded stent segments are described herein. Stent segments which are able to slide freely relative to one another along the deployment catheter prior to expansion may be secured to one another when expanded and/or deployed into the vessel. Securement upon expansion of the stent segments may be accomplished, in part, by utilizing one or more coupling mechanisms between adjacent stent segments which securely interlock the segments to one another by taking advantage of the changing geometry of the stents during expansion.Type: ApplicationFiled: March 19, 2007Publication date: September 20, 2007Applicant: Xtent, Inc.Inventors: Stephen Kao, Jeremy Dittmer, David Lowe
