322 results about "Foot pressure" patented technology

This invention relates to a system that continuously monitors pressure and force on the foot, analyzes and visualizes the pressure and force exerted on said foot in real-time. The invention measures pressure and force applied to a plurality of sensors placed in various points of an orthotic, shoe, shoe lining, insert, sock or sock type device. If the sensors detect pressure or force, the sensors send a signal to a microcomputer processor located in the shoe that subsequently analyzes and sends the data wireless to either a handheld electronic device, a personal computer, an electronic data capture system or a software program. The handheld electronic device or the personal computer then displays the data to an operator of the device or computer instantaneously; while the data capture system or program forwards the information to a handheld device and / or personal computer.

An orthopedic walking boot promotes rapid healing of diabetic foot ulcerations by lowering the maximum peak pressure imposed upon the foot. The walker has a hard unyielding shell which is designed for walking. The shell closely and rigidly supports a mid-sole in a foot-shaped bed. The mid-sole has a foot-shaped cavity with rounded sides adapted to form resilient support for the heel, arch and sides of a foot in addition to the bottom of a foot. A conformable inner-sole is adapted to fit over the foot-shaped cavity in the mid-sole and be compressed in response to foot pressure between the sides and bottom of the foot and the sides and bottom of the foot-shaped cavity in the mid-sole thereby compensating for small differences between the shape of the foot and the shape of the cavity. Weight applied to the foot is transferred to the walking shell by contact between the sides of the foot, arch, and heel and the arch, heel and sides of the foot-shaped cavity as well as the bottom of the cavity thereby decreasing the peak or maximum unit pressure on the plantar surface of the foot. A breathable bootie which wraps the foot and lower leg in a protective “cocoon” is preferably secured to the upper surface of the insole thereby preventing foreign materials from entering the foot cavity.

A shoe comprising a foot retaining portion having a heel area and having an interior side, the interior side sized and shaped to hold a foot and including an upper portion, the upper portion optionally lined with a pliable material; a first exterior insole layer having therein a cut-out adjacent the heel area of the foot retaining portion, the first exterior inside layer having an interior surface forming the bottom of the foot retaining portion and that is lined with pliable material; a second exterior insole layer having a heel strike pad sized and shaped to fit within the cut-out of the first exterior insole layer, the heel strike pad comprised of a material that absorbs and disperses heel strike forces; a third exterior insole layer sized to fit the foot retaining portion and having therein a cut-out adjacent the heel area of the foot retaining portion, the third exterior insole layer comprised of a material that provides foot cushioning; a fourth exterior insole layer adjacent the third exterior insole layer comprised of a material that provides foot tactile stimulation when foot pressure is applied thereto; an outsole layer adjacent the fourth exterior insole layer comprised of a material that provides outsole flexibility and skid resistance, the outsole layer having a heel with an optional depression therein; and an optional heel strike pad sized and shaped to fit within the depression of the heel of the outsole layer and comprised of a material that absorbs and disperses heel strike forces.

An innovative shaped memory insole with re-adjustable supporting pads, an insole structure that can be tailor made on the spot, and thereafter can be repeatedly reshaped through a processes of non-destructive structural re-adjustment and free of glue to do re-assembly, using a design of re-adjustable structural supporting pads and a shape memory insole to meet the needs of different foot pressures on the user, thereby alleviating pain to the user's feet, providing stability to the user's ankles and improving the balance of the lower limbs.

A footwear assembly requires a wearer to adjust in order to maintain stability while standing, walking, etc. The assembly includes an outer sole having a flexible shell surrounding a hollow interior substantially filled by a plurality of unconnected, substantially non-deformable particles. Foot pressure applied to the outer sole results in movement of the plurality of particles, and the resiliency of the shell allows it to assume a variety of different configurations based in part on the portion to which pressure is applied. The resiliency of the shell further facilitates normal biasing thereof and the particles therein into a normal, non-compressed orientation. The tendency of the outer sole to assume a variety of different configurations will, in some circumstances, require a wearer to adjust the corresponding foot and / or leg in order to maintain normal stability, at least when foot pressure is applied to the outer sole.

This invention introduces several methods, apparatus, and systems for controlling musician audio effects or musical instruments wirelessly from the performer's footwear. In one embodiment, the performer's foot motions are monitored using a motion detection device and compared against a set of criteria by a microprocessor to activate or deactivate one or more audio effects that are ready or “armed.” Once the foot controller is activated, a radio transmits sampled foot pressure that is used by the Base Unit to modulate all armed audio effects capable of being modulated. Tactile feedback is provided in the footwear as a means to confirm system status changes.

A measuring device (10) is used for generating an imprint of a patient's foot. The imprint includes a first set of at least two differentiable color density markings. The first set of differentiable density markings each correspond to a different pressure exerted on the measuring device by different areas of the patient's foot. A calibration card (50) is provided with an indicia including a set of at least two differentiable density markings. Each differentiable density marking in the second set of differentiable density markings on the calibration card has a viewing opening (56) disposed within, such that when the viewing openings in the calibration card are placed over the imprint of the patient's foot, the first set of different density markings from the imprint are viewable through the viewing openings so that they are readably comparable to the second set of differentiable density markings in the indicia on the calibration card.
