Abstract: A surface acoustic wave device is provides and comprises a flexible substrate having a first side and a piezoelectric film attached to at least a portion of the first side of the flexible substrate. The piezoelectric film can have a first side and a second side. A surface acoustic wave circuit can adjoin at least a portion of the first side of the piezoelectric film. These devices can comprise thin and flexible substrates, such as polyimide to make the devices flexible. If adhesive is applied to the back of devices constructed in accordance with the invention, such devices can be adhered to almost any surface, even a curved surface. The devices of the present invention can be easily integrated with other devices.

Abstract: The present invention includes a band for a person's limb or digit. The band has a body portion, at least one first strap portion extending in cantilever fashion from one side of the body portion toward another side of the body portion and at least one second strap portion extending in cantilever fashion from the another side of the body portion toward the one side of the body portion. The body and strap portions define an opening for receiving a limb or digit. The first and second strap portions flex when the band receives the limb or digit to securely and comfortably hold the band on the limb or digit. The band also includes at least one weight releasably securable to the body portion for increasing or decreasing the weight of the band.
