Patent number: 11597065Abstract: Pressure gauges according to this invention provide pressure measurement on all brands of crimping tools, including 6-Ton D3 tools. In particular, this design eliminates the need to remove the tool crimp head to measure the pressure of the crimping tool. Additionally, this design eliminates the need to install additional dedicated fixtures on the crimping tool to measure the ram pressure. This design incorporates a self-centering profile to avoid side-loading when mounting the pressure gauge in the crimping tool. The dial indicator on pressure gauges of this invention captures and holds the maximum pressure reading with the use of a simple manual lever. The lever can be easily reset for the next pressure reading. Pressure gauges according to various embodiments of this invention include dual piston pressure sensors. Additionally, pressure measurement is accomplished with a simple hydro mechanical manometer display.Type: GrantFiled: August 24, 2020Date of Patent: March 7, 2023Assignee: Ilsco, LLCInventors: James Bider, William Mitchell, Bill Wolins

Publication number: 20220207565Abstract: Methods for in-vehicle contextual promotions are described herein. In a first method a driver receives an in-vehicle promotion (for either food or fuel) based on a time of day, their location, route, favorite items, favorite vendors, and nearby vendors. The driver taps the promotion and receives a list of favorite items. The driver makes a selection of the favorite items, makes a payment for the selected product using an e-wallet, and picks up the selected product. In a second method, the driver may receive an in-vehicle promotion, including a “remind me later” link. When the user taps on the link, they may then access the promotion at a later time on their mobile phone app outside of the vehicle. The user taps on the saved link and is redirected to a vendor's website. The user may make a purchase for a product at the vendor's website at this later time.Type: ApplicationFiled: November 19, 2021Publication date: June 30, 2022Inventors: William Mitchell Dornich, John Jasper, Paul Doucette, Victoria Repice, Marti Gold
