Apple patents "Exciter" technology for devices, including a "cyclocomputer"

I think you're a little off on the cyclocomputer. It's not for bicycles. It would be for exercise equipment. For example. Your iPhone or iPod would be able to get data right off the exercise bike and apply it to an app. Much like Nike+.

It would be cool if all the exercise equipment you used in the gym could send all the data to your iOS device. Like reps, speed, time, distance, etc. Then an app customizes a workout for your defined goals. Kinda like Wii Fit. Maybe an encouraging voice comes over when it knows you need to push it some more. Like a virtual personal trainer.

Why they are not using Bluetooth? Maybe this method they are working on drains the battery less? Higher bandwidth? Doesn't require pairing. It just works. Also, Apple wouldn't mind it to be patented proprietary technology so other makers couldn't see their idea and just rip it.

I really don't think it for bike riders to exchange info. C'mon.

I would be satisfied with complete fast wireless syncing of all data between mobile devices and computers and the cloud-going in any direction and including lots of storage.

I use "Bump" to share contact cards, photos, calendars, etc. with the iPhone already. You have to physically bump the two iPhones (fairly close anyway), but that's about as easy as I would want to make it.

Why would I want the information of a person I've passed in the street? Seems perfect for horndogs though. Yeah - Horndogs and information hoarders will love this app.

Hmmm - on second thought.

Palms had this what, 10 years ago, using IR. You could beam your "business card" to another Palm.

Of course, you had to point the Palms at each other, but that was actually a reasonable restriction. The innovation here is doing this wirelessly - meaning non-directional-, and the consequences could be implicit sharing as well as explicit sharing.
