Filed:

Nov 19, 2012

Appl. No.:

13/680865

Inventors:

WILLIAM LANGFORD - GREENWICH CT, US
JACKSON DOLAN - TRUMBULL CT, US

Assignee:

CARDIBO, INC. - BOSTON MA

International Classification:

G08C 19/00

US Classification:

34087007

Abstract:

To provide users the ability to track their cardiovascular exercise and determine cardiovascular exercise machine usage, the present system and methods describe an activity tracking platform. The platform includes a wireless sensor configured to monitor a piece of cardiovascular exercise equipment. The sensor can be configured and positioned to monitor a moving part of the exercise equipment, such as the spinning tread of a treadmill or the circular movement of a bike peddle. Responsive to detecting activity, the sensor can associate the data with a specific user and, using a wireless sensor network, transmit the data to a central server. The platform provides the user an associated website, where the user may view historical workout information, current exercise equipment usage at a local gym, or current workout goals.

Abstract:

Electromagnetic digital materials are made up of a set of voxels, some of which are made from electromagnetically active materials. Each voxel is adapted to be assembled into a structure according to a regular physical geometry and an electromagnetic geometry, and a majority of the voxels in the set are reversibly connectable to other voxels. Voxels in the set may differ in material composition or property from other voxels in the set. Voxels may be arranged into multi-voxel parts that are assembled into the structure according to a regular physical geometry and the electromagnetic geometry. Electromagnetic structures may be made from the electromagnetic digital material, and may be fabricated by an automated process that includes assembling a set of voxels by reversibly connecting the voxels to each other according to a regular physical geometry and an electromagnetic geometry and assembling the reversibly connected voxels into the electromagnetic structure.
