Abstract: A speaker can have a main body with a generally spheroidal shape, which can be supported standing on its end. The speaker can include a subwoofer that faces forward. A plurality of mid-range drivers can be distributed around the sub-woofer, facing generally forward and radially outward. A plurality of tweeters can be distributed around the sub-woofer, facing generally forward and generally outward. The outer housing portion of the speaker can be covered with a fabric material. A user interface ring 162 can be touch sensitive to receive input, and can have a plurality of lights that can be illuminated separately to convey information to the user.

Abstract: A tire and membrane system includes a tire, an electronics package, and a membrane body attached to the electronics package. A width of the membrane body is less than 120% of a width of a tread of the tire. A length of the membrane body is less than 50% of a circumference of the tire. A bottom surface of the membrane body is configured to lie flat against an inner surface of the tire. The membrane body is not attached to the tire.

Abstract: A point-of-care device allows for a simple and rapid determination of blood coagulation properties. The device is comprised of an absorbent material and a clotting agent. In operation, a quantity of blood is first allowed to clot, after which remaining serum is allowed to migrate through the absorbent material. The serum migration distance is proportional to the clotting time of the patient sample as routinely determined. The device can be used directly at the bedside of a hospital patient for immediate test results, or can be used for patient self-monitoring.
