Abstract: Systems and methods for social and other sporting activities. A system according to one such aspect of the invention comprises a sensing device that is attached to an object, such as a skateboard (by way of non-limiting example), for measuring characteristics thereof. It communicates those characteristics wirelessly, e.g., via bluetooth, to a mobile device, such as a cell phone, personal digital assistant, or the like (by way of non-limiting example). That device can log and/or display those characteristics, graphically, for study or analysis by the operator (e.g., the skateboard enthusiast) or others.

Abstract: Disclosed herein are methods and apparatus for electronic commerce. By way of example, in one embodiment such methods and apparatus enable a buyer's digital data processor to make requests to an on-line store to view purchase options for a selected product/service as well as to view benefits for consummating those transactions. Further, a store's electronic display/register or a handheld computing device may enable a shopper in a physical store to view such information and earn benefits. Those benefits may differ by item and seller and may include money and/or points. With such money and/or points having been accumulated through on-line and brick and mortar store purchases, e.g. in buyer's account, a buyer's digital data processor can facilitate redemption of the money and/or points at the same or other stores, for example to purchase additional items or for other purposes.
