Publication number: 20240123650Abstract: Handheld power tools with kickback detection and methods of detecting a kickback condition of a handheld power tool are disclosed herein. The methods include moving an implement of the handheld power tool within an implement motion plane and in detecting motion of the handheld power tool. The methods also include determining that the kickback condition exists based, at least in part, on the motion of the handheld power tool. In some embodiments, the handheld power tool is a circular saw that includes a user-actuated assembly. The user-actuated assembly includes a motion sensor, a controller, and a motor. The circular saw also includes a workpiece support and a pivot. The motion sensor is configured to detect acceleration along an acceleration detection axis that extends a threshold pivot axis-acceleration axis distance of at most 4 cm from a pivot axis of the pivot.Type: ApplicationFiled: February 18, 2022Publication date: April 18, 2024Applicant: Festool GmbHInventors: Dominik Hilpert, Markus Schmid, Harald Ruhland, Stefan Staib, Christian Schock, Markus Wildermuth, Matthias Kübeler

Publication number: 20210348804Abstract: An embodiment in accordance with the present invention includes an EGS configured to allow the commercial production of electrical energy. One criteria of an EGS according to the present invention is that the temperature and volume of the fluids extracted are sufficiently high and large enough as to allow the commercial production of electrical energy. The system is able to operate for at least N years before the extracted fluid falls below the minimum temperature needed for energy production. Additionally, fractures are separated from each other by a sufficiently large volume of rock (Vcrit) relative to the fractures surface area such that the ratio of the rate of heat extraction to the rate of heat supply controlled by the thermal conductivity of the rock is such that the intervening rock is cooled at a rate that is sufficiently slow to be economic.Type: ApplicationFiled: July 21, 2021Publication date: November 11, 2021Applicant: The Johns Hopkins UniversityInventors: Bruce D. MARSH, Markus HILPERT, Peter Anderson GEISER

Patent number: 11098565Abstract: An embodiment in accordance with the present invention includes a method for estimating the permeability of fractured rock formations from the analysis of a slow fluid pressure wave, which is generated by pressurization of a borehole. Wave propagation in the rock is recorded with TFI™. Poroelastic theory is used to estimate the permeability from the measured wave speed. The present invention offers the opportunity of measuring the reservoir-scale permeability of fractured rock, because the method relies on imaging a wave, which propagates through a large rock volume, on the order of kilometers in size. Traditional methods yield permeability for much smaller rock volumes: well logging tools only measure permeability in the vicinity of a borehole. Pressure transient testing accesses larger rock volumes; however, these volumes are much smaller than for the proposed method, particularly in low-permeability rock formations.Type: GrantFiled: December 3, 2018Date of Patent: August 24, 2021Assignee: The John Hopkins UniversityInventors: Markus Hilpert, Peter Anderson Geiser, Bruce D.

Patent number: 8033745Abstract: A digital printer includes a digital printing unit for digital printing an image onto a printing substrate during relative movement between a print head and the printing substrate, and a printing table for holding the printing substrate during the digital printing. The printing table is firmly fixed to the digital printing unit during the digital printing of the image onto the printing substrate and is released from the digital printing unit prior to and after the digital printing of the image onto the printing substrate. The printing table may be moved between a printing position, in which it is firmly fixed to the digital printing unit, and a printing substrate feeding position, in which it supports feeding and removing of the printing substrate from the printing table.Type: GrantFiled: May 30, 2006Date of Patent: October 11, 2011Assignee: Agfa Graphics NVInventors: Bart Verlinden, Bart Verhoest, Werner Van De Wynckel, Albert Brals, Markus Hilpert
