The patent claims, inter alia:
A foot balancing device, consisting of:
a shoe insert having a foot contact surface and a bottom surface, the shoe insert defining a front-of-sole region, an arch region, and a heel region sequentially arranged in a longitudinal direction of the shoe insert, the foot contact surface and the bottom surface each being a flat surface;
a main balancing element formed as a protuberance in the arch region and located on the shoe insert at a position corresponding to a fulcrum for a front part of a sole of a user’s foot and a heel of the foot;
wherein the main balancing element is located in the arch region of the shoe insert corresponding to a geometric center between a first metatarsal bone point, a fifth metatarsal bone point, and a heel point of the shoe insert,
wherein the main balancing element protrudes above the flat surface of the foot contact surface or protrudes below the flat surface of the bottom surface, and
wherein the first metatarsal bone point corresponds in position to a first metatarsal bone of the foot, the fifth metatarsal bone point corresponds in position to a fifth metatarsal bone of the foot, and the heel point corresponds in position to the heel of the foot; and
a first auxiliary force-transferring element and a first auxiliary balancing element, wherein the first auxiliary force-transferring element is formed as a protuberance in the arch region and is located rearward of the main balancing element and adjacent to the heel region, and the first auxiliary balancing element is formed as a protuberance in the arch region and is located forward of the main balancing element corresponding to a transverse arch of the foot, wherein a cross-sectional area of the main balancing element is greater than cross-sectional areas of each of the first auxiliary force-transferring element and a first auxiliary balancing element.
The patent attorney that drafted U.S. Patent No. 9,913,508 provided that
The device also includes a mount configured to mount the housing to a first external body surface. The first external body surface is at a wrist location of a particular arm of a wearer. The device also includes a first electrical contact disposed on an inner surface of the mount. The first electrical contact is configured to contact skin at the first external body surface responsive to the housing being mounted to the first external body surface. The device also includes a second electrical contact disposed on an outer surface of the mount. The second electrical contact is configured to be contacted by skin of a second external body surface. The second external body surface is at a location other than the particular arm. The device also includes a signal conditioner disposed in the housing. The signal conditioner is electrically coupled to the first electrical contact and the second electrical contact. The signal conditioner is configured to determine data indicative of a biological state of the wearer based on voltage fluctuations between the first electrical contact and the second electrical contact.
Figure 1 describes the foot balancing device in an embodiment of the present invention includes a shoe insert 10, a main balancing element 20, a first auxiliary force-transferring element 31, a second auxiliary force-transferring element 32, a first auxiliary balancing element 41, a third auxiliary force-transferring element 33, a second auxiliary balancing element 42, and a third auxiliary balancing element 43.
