I don't know if there are off the shelf receivers for OEMs to integrate into their equipment. Talk to Sports Instruments and Polar. Those were the two big players 5(?) years ago when I wrote the PIC code to interpret the pulses for the bike logger. A custom receiver was designed for that product although I wasn't the one that did that design. By the way, this was done for the ancestor of what is now the PowerTap bicycle ride logger from CycleOps. The product was sold to different companies twice I think and I haven't been envolved with it for years. I think they are now using TI micros although the earlier versions used PICs. ****************************************************************** Embed Inc, Littleton Massachusetts, (978) 742-9014. #1 PIC consultant in 2004 program year. http://www.embedinc.com/products -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
