Yoyodyne Propulsion Systems is proud to offer the new model Interocitor Mark IV.

Offering significant upgrades to the 451F model, Mark VI production has been moved to Yoyodyne's Grover's Mills, New Jersey Aerospace facility. The current line of Interocitors continues to incorporate greater advances than hitherto known in the field of electronics. At the same time Yoyodyne engineers, according to production manager John Bigboote, have improved performance they are able to design the Mark VI to incorporate 20% fewer parts than the 2486 required for the 451F with a concomitant improvement in reliability. The most popular production models are still available including those incorporating a planetary generator, a volterator, an astroscope, and (always popular with home makers) the electron sorter. Dr. Cal Meacham, despite the shift of production from his Ryberg facility, maintains a 49% equity stake in all Interocitor models as well as his position as chief scientist in charge of design. Chief of R&D, John Carefulwalker, references benchmark rates of four lane road construction in the 30 to 45 second/mile range verses two to three minutes for the 451F. If you have been thinking of adding an Interocitor to you defense, communications, or energy management systems: If you have reached the limits of your 451F's capabilities and are looking for an upgrade: If you have some spare room in your garage or shop:

It is time to experience life with a Yoyodyne Propulsion Systems Interocitor Mark VI.

As you know, matter is composed mostly of empty space, right down to the quantum level: within an atom, most of that atom's total volume consists of relatively vast spaces between the subatomic particles, although the particles do remain tethered to each other by electromagnetic force. Early quantum theory suggests that EM force may consist of "virtual photons" that have no mass and naturally fill such otherwise empty spaces. The overthruster powers two colliding beams (one stream of electrons, one of positrons) which annihilate each other, creating create intermediate vector bosons as a by-product. The vector bosons are then magnetically collected and focused into another beam, now capable of imparting mass to those pesky virtual photons, thereby weakening the EM force that binds matter. Everything reverts to normal pretty quickly, but a fast-moving object (such as Buckaroo's jet car) can pass through the affected matter before the window closes. Greater detail can be found in "Moving Through Matter with Buckaroo Banzai" by Dr. Cary I. Sneider of the Lawrence Hall of Science at Berkeley, first presented at a National Science Teachers Association convention in Boston in April 1984.

Our patented ANGi sensor calls for help when you can’t. In fact, it’s the first device to protect you before, during, and after a crash. It does this through a pairing with our Specialized Ride App for iOS or Android devices. And if it detects a crash, it commences a countdown that, if you’re ok, you can stop and keep riding. If, however, ANGi determines that you’re in need of help, it’ll send an alert to your selected contacts with your last known GPS coordinates and a message that you’re in need of help. What about if you’re out of service coverage? ANGi has a plan for that. Just set your estimated ride time before you head out when you know that your ride will take you out of range. All you need is an active data signal when you start your session. And if you haven’t completed your ride within that time frame, ANGi will send a notification to your contacts with your last uploaded location. - ANGi is a ride tracker, crash detector, and safety beacon. - Includes a one-year subscription to Specialized Ride Premium app. - Detects and reports potentially dangerous helmet impacts to the Specialized Ride app, which notifies your emergency contacts and sends them your most recent GPS coordinates. - Additional premium features include start ride notifications and ride-time alerts. - Attaches to Specialized ANGi-ready helmets. - Approximate six months' battery life on a 2032 coin cell battery. - Weight: 10 grams w/ battery - Two-year sensor warranty
