Publication number: 20210009180Abstract: The Pallet Loading Height Limiter is a very simple, and yet effective, non-powered, adjustable device for helping warehouse workers keep a shipping pallet load within safe and proper limits for height (and, consequentially, also weight). The device rolls on locking casters for easy use and storage. The device's frame has reinforcing brackets that minimize damage from passing forklifts, etc. The device's design makes it easy to repair if it is ever damaged. Because there is no globally-accepted standard for pallet sizes, this device may be made in various sizes (usually determined by country of origin of the pallet). That said, the North American pallet size (40? by 48?) is the standard used for this application. This device works equally well with stringer- or block-type pallets. Using this device should help minimize material-handling injuries to workers that handle loaded pallets.Type: ApplicationFiled: July 9, 2019Publication date: January 14, 2021Applicant: 1SG EnterprisesInventor: Thomas Frantisekovich Kovach

Publication number: 20210009201Abstract: Systems and methods are provided for generating adapted tuning parameters for target slip estimation, the parameters being adapted to real-time road surface conditions. The method includes, receiving, from a road surface detection module, a road surface condition, Sn, from among N road surface conditions S, range of friction, mu, and a confidence level, Ci. The method receives sensor system data from a sensor system, and determines, as a function of Sn, range of mu, and Ci, initial estimator values including an estimated initial frictional force {circumflex over (?)}(0), an initial gain, P0, and an initial projected range of signal bounds, (Pu) and (Pl). The method tunes (i.e., adapts) the initial estimator values to generate therefrom adapted tuning parameters based on received inputs. The method outputs adapted tuning parameters.Type: ApplicationFiled: July 11, 2019Publication date: January 14, 2021Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Joonho Lee, Qingrong Zhao, Bakhtiar B.
