Abstract: Roof shingles and methods of production thereof are provided. The roof shingles may include ethylene-propylene-diene terpolymer (“EPDM”). The EPDM may include an outward-facing surface and a substrate-facing surface. The outward-facing surface may include a reveal and a conceal. The reveal may be visible when the roof shingle is installed and the conceal may be covered by an upslope adjacent roof shingle when the roof shingle is installed. The roof shingle may include a reinforcement core. The reinforcement core may include galvanized steel. The reinforcement core may be embedded within the EPDM. The roof shingles may include adhesive sealant. The adhesive sealant may be applied to the substrate-facing surface for binding the roof shingle to a downslope adjacent roof shingle or a substrate. The roof shingles may include a plurality of EPDM granules being located on at least a portion of the surface of the reveal.

Abstract: A low cost eccentric mass motor vibrotactile transducer provides a point-like vibrational stimulus to the body of a user in response to an electrical input. Preferably the eccentric mass and motor form part of the transducer actuator moving mass. The actuator moving mass is constrained into vertical motion by a spring between the actuator housing and moving mass. The actuator moving mass is in contact with a skin (body) load. The actuator housing is in simultaneous contact with the body load. The mass of the motor/contactor assembly, mass and area of the housing, and the compliance of the spring are chosen so that the electromechanical resonance of the motional masses, when loaded by the typical mechanical impedance of the skin (body), are in a frequency band where the human body is most sensitive to vibrational stimuli 150-300 Hz.

Abstract: A system and method is provided that enables a postal customer to order a shipping label on-line via the internet. The label may be a mailing label to be placed on letters or parcels. The label includes information such as postage, delivery address, return address, and a barcode for tracking delivery information. A user may request both a label and postage in what, to the user, appears to be a single computerized connection on a single internet web-page. A postage indicia is provided through a postage provider with whom the user has a deposit or credit. The label itself may be generated through a label-generating application hosted or generated by an entity separate from the postage provider.
