Abstract: Methods and a system for in-vehicle contextual promotions are described herein. In a first method a driver receives in-vehicle promotions on a predetermined route and user-defined favorite vendors. The driver taps on the promotion and receives a list of favorite items. The driver makes a selection of one of the favorite items, makes a payment for the selected product using an e-wallet, and picks up the selected product. The driver may also receive loyalty rewards. 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 access the promotion at a later time on the user's mobile phone app. 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.

Abstract: 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.
