VacPuc is a wireless, batteryless pressure sensor for measuring vacuum bag pressure in composite manufacturing processes – resin infusion/VARTM, and both OoA and autoclave prepreg. VacPuc is powered by inductive power transfer from a standard mobile phone and data is displayed and logged on an easy-to-use mobile app. A vacuum leak check is one of the fundamental quality assurance checks in composite manufacturing, yet the industry-standard method requires a bag penetration, which itself is a high-probability leak point. VacPuc removes the requirement for a bag penetration to measure the vacuum and perform a vacuum leak check.

About

RCT

Features

RCT is a budgeting app that scans your receipts and categorizes every item on them one line at a time, instead of filing a whole shop under "groceries". Photograph a receipt and your spending history fills itself in, item by item, in seconds. You know you spent money last week. You're just not entirely sure where it went. That's the part RCT fixes. Snap a photo of any receipt, let it be a supermarket run, a coffee stop or a 3am food delivery. Every single item is categorized automatically, and added to your spending history without you lifting another finger. ITEM-LEVEL SCANNING Other apps track "groceries". RCT tracks the cookies, the overpriced juice, and the chocolate bar you added at the checkout. Point your camera, tap, and every line on the receipt is logged and categorized in seconds. No manual entry. No guessing. REPORTS THAT TELL YOU THE TRUTH Your monthly breakdown goes deeper than broad categories. See what you actually spend on snacks vs. fresh produce, coffee vs. alcohol, eating out vs. clothes. The first time you check, it might sting a little. That's kind of the point. BUDGETING THAT MAKES SENSE Set a monthly budget and RCT handles the maths. You'll always know how much you have left, whether you prefer to budget weekly or daily, so that you can make your best decisions instead of just hoping for the best.
