Patent number: 11809894Abstract: The present disclosure describes methods and systems for virtually calibrating geometric sensors with overlapping fields of view. In some embodiments, a geometric sensor may be virtually calibrated by applying a correction value to profile data obtained by the geometric sensor to generate adjusted profile data. The correction factor may be determined based at least in part on X-Y offsets and/or rotational offsets of prior profile data obtained by the geometric sensor relative to corresponding profile data obtained by a reference geometric sensor, and may be recalculated or updated as new sets of profile data are obtained. The adjusted profile data may be used in place of the original profile data in various data processing operations to functionally offset a positional error of the geometric sensor.Type: GrantFiled: November 19, 2021Date of Patent: November 7, 2023Assignee: USNR, LLCInventors: Douglas G. Strasky, Erik W. Kalf, Brian Walts

Publication number: 20210086391Abstract: Embodiments provide methods, apparatuses, and systems for cutting wood workpieces, such as logs and cants, into desired products. In various embodiments, after a log is chipped into a cant, the cant may be scanned and re-optimized based on the new scan data and information about the source log, such as simulated orientation parameters, a 3D model, and/or potential cut solutions. In other embodiments, data from multiple sensor types may be used in combination to detect splits in logs, cants, or both. Optionally, re-optimization and split detection techniques may be used in combination to improve wood volume recovery, value, and/or throughput speed.Type: ApplicationFiled: December 7, 2020Publication date: March 25, 2021Applicant: USNR, LLCInventors: Douglas G. Strasky, Stephen DOIEL, Gerald David LARSON, Robert ARNOLD, Ryan MUNION, Dimitrios Paul Marinakis

Patent number: 5991670Abstract: A control system interrelatedly controls the electric power output and oxidant supply in a fuel cell electric power generation system. The power generation system comprises at least one fuel cell stack, and a plurality of electrical loads powered by the fuel cell stack, including an electric traction motor for propelling the vehicle, and a compressor for delivering oxidant gas to the fuel cell stack. The electric power output of the at least one fuel cell stack is dependent on the compressor speed. The control system comprises a summing device for determining the total instantaneous power demand of the electrical loads based on a plurality of sensed power demand signals, and a processor for generating a feed-forward output signal for adjusting the compressor speed to a value predicted to give fuel cell power output sufficient to satisfy the instantaneous power demand.Type: GrantFiled: January 3, 1997Date of Patent: November 23, 1999Assignee: dbb Fuel Cell Engines GmbHInventors: W.

Patent number: 5771476Abstract: A power control system for controlling the supply of a reactant gas, such as air, for reaction within a fuel cell stack used to power, for example, a motor vehicle is set forth. The disclosed system may be used to reduce or eliminate compressor revving and instabilities common to prior systems in which fuel cell power output is dependent upon a flow of a reactant gas through a fuel cell stack, the flow of reactant gas being determined by the compressor speed.Type: GrantFiled: December 29, 1995Date of Patent: June 23, 1998Assignee: DBB Fuel Cell Engines GmbHInventors: W.
