Patent number: 11718180Abstract: A brake controller has a control dial with a series of full color LEDs arranged around the dial. The dial with its LEDs is in a module mounted on the dash of the towing vehicle and connected by a cable to a main module mounted out of sight. The dial is a rotary encoder pushbutton mounted on the same circuit board as the LED chips. Status information is output using the LEDs primarily based on color. Substantially all setting input is provided solely by user manipulation of the dial, pushing the dial in to change setting input mode, with the value of the input reflected in the number of LEDs being lit in a color corresponding to the brake controller setting being changed, as the user rotates the dial either clockwise or counterclockwise to change setting values.Type: GrantFiled: March 30, 2021Date of Patent: August 8, 2023Assignee: Curt Manufacturing, LLCInventors: Joecyl Sanchez, Harsh Desai, Robert Lange, III, Praveen Reddy Muddasani

Publication number: 20230221214Abstract: A method is proposed for generating a series of ultra-thin sections of a microscopic sample (10), wherein the sections (11) are detached from the sample (10) using an ultramicrotome (100) and wherein the sections (11), which are detached from the sample (10) are caused to float on a liquid surface and are thereafter transferred onto a solid carrier element (20). For at least for some of the sections (11) detached from the sample (10) a position and an orientation on the solid carrier element (20) are determined by monitoring the placement of these sections (11) onto the solid carrier element (20) using a monitoring system (400) comprising a camera (410), obtaining monitoring data. A method (2000) for the three-dimensional reconstruction of a microscopic sample (10), a microtome system and a computer program are also part of the present invention.Type: ApplicationFiled: June 17, 2021Publication date: July 13, 2023Inventors: Robert KIRMSE, Robert LANGE, Peer Oliver KELLERMANN, Robert RANNER, Mario NOESSING

Patent number: 11342860Abstract: Several DC link converters are interconnected at first and second terminals. Each DC link converter has an input-side rectifier connected to a power supply and an output-side inverter connected to a load, and a DC link with a DC link capacitor. Potentials of the DC link capacitor are connected via first and second lines respective first and second terminals. A switching element and a parallel-connected diode are arranged in at least one of the lines. A control device controls the switching element depending on the DC link voltage and/or as the current flowing through the respective line, allowing the DC link capacitor to be charged, but not discharged via the diode when the switching element is non-conducting, and to be at least discharged when the switching element is conducting. An inductor is arranged in at least one of the lines, and a flyback diode is connected between the lines.Type: GrantFiled: November 15, 2018Date of Patent: May 24, 2022Assignee: Siemens AktiengesellschaftInventors: Robert Lange, Marco Seja
