Abstract: A protective headgear device, or helmet, protects against head injuries such as concussions and CTE by imposing a network of constant force members (CFMs) between an outer impact shell and an inner fitted capsule engaging the skull/head surface. CFMs exhibit a force absorbing behavior that differs from conventional linear spring behavior that impose a counterforce proportional to the displaced distance. CFMs occupy a compact void between the outer impact shell and the inner fitted capsule by component miniaturization and tethers that redirect forces within the void. An absence of conventional foam and straps increases accommodation for the CFMs and connection tethers/attachments. The CFMs exhibit a substantially constant force that avoids a sharp impactful response associated with head injuries.

Abstract: A surface topography analysis invokes a sensor device for receiving a series of values from a sensor element of measurement equipment adapted to quantify an input stimuli into a surface height value, and computes consecutive curvatures from the received series of values. An aggregate value (sum) of the consecutive curvatures is compared to a threshold, and based on the comparison, the approach concludes that at least one of the consecutive curvatures corresponds to an outlier. The set of values are based on a signal that is continuous, although not necessarily differentiable, as received from the measurement equipment. Such measurement equipment embodying the sensor device may further comprise at least one of atomic probe microscopes, interferometric microscopes, confocal microscopes, scanning laser microscopes, profiling instruments, scanners, and CMMs.

Abstract: A force absorbing device for a footwear appliance includes a shoe upper and a shoe sole having a planar sole surface, such that forces between the shoe upper and planar sole surface in ground contact are absorbed by force mitigation structures disposed in the shoe sole. A footwear article includes a split-sole system that redefines a shoe sole as coplanar surfaces having a force mitigating interface for receiving sudden forces and effectively mitigating these forces by storing kinetic energy and releasing it over time. An elastic field in the force mitigation structure is defined by a resilient material adapted to deform in response to the received force. Frictional engagement between the upper and lower sole may also be augmented by surface characteristics such as dimples, voids and lubricants, in addition to interference engagement with an elastic field.

Abstract: A ski binding device having a plate adapted to engage the ski binding, in which the plate has a heel end and a toe end, and a heel absorption mechanism is adapted to absorb excessive lateral pivoting force from the heel of a ski boot. A restrictor biases the heel into engagement with a heel receptacle. A dual pivot engages the toe end of the plate for permitting both downward movement of the heel end and lateral movement of the heel end out of alignment with the ski. The lateral pivoting force corresponds to release of potentially harmful forces. The restrictor is responsive to upward force from the toe end, as results from disproportionate backweighting of a skier. The restrictor disengages the heel end from the heel receptacle based on a predetermined release force, and permit lateral outward displacement of the heel end upon disengagement of the heel.

Abstract: A protective sports garment includes a device adapted to overlay an anatomical region likely to experience a concentrated load such as a shoulder, knee or elbow joint. The device includes a base resting on an anatomical region, and a cap responsive for controlled displacement towards the base in response to the external loads. These loads may encompass both force and torque, as the load may tend to exert in different directions. The base rests on the joint area or anatomical surface to be protected. This may be part of a larger assembly such as a shoulder pad set, catcher's pad assembly, or other integration of protective sports gear defining a surrounding garment or textile assembly such as a pad set. The cap is tethered or suspended around the base for controlled, force dispersed displacement toward the base and may include a "sandwiched" structure of additional compressible material.

Abstract: A force dissipating device in a footwear appliance includes an actuator responsive to a displacement force from a shoe sole surface, and an elastic field of resilient, compressible material. The elastic field is elongated in a direction aligned with the displacement force, and an inclined surface is attached to the actuator and disposed against the elastic field. The actuator is adapted for movement parallel to the elastic field, while the inclined surface is oriented to compress the elastic field in a direction defined by the inclined surface. The inclined surface is oriented at an angle to compress the elastic field in a direction substantially perpendicular to vertical actuator displacement, thus providing a constant region of opposed, compressive force that is generally constant, rather than increasing with displacement distance.

Abstract: A force absorbing device for a footwear appliance includes a shoe sole having a planar sole surface, such that the shoe sole is adapted to be disposed against a ground surface such as turf, grass or dirt. A ground interface member having a general appearance of a footwear cleat extends from the planar sole surface. Within the sole, the ground interface member couples to a force mitigation assembly for absorbing forces against the cleat. The force mitigation assembly includes an elastic field of a resilient, compressible material, and an inclined surface is disposed against the elastic field and oriented to compress the elastic field. A linkage or connecting surface transmits a displacement force for disposing the inclined surface across the elastic field, where the inclined surface compresses the elastic field as it moves across. In response, the elastic field exerts a counterforce against the ground interface member.

Abstract: A ski binding reduces a likelihood of injury to the anterior cruciate ligament (ACL) and the tibia is accomplished by absorption in the binding to limit loads transmitted through the boot-binding interface. Release based on an injury threshold includes a binding response tower attached to the ski and adapted for selective engagement with the ski, such that the binding response tower permits biased vertical and lateral horizontal displacement, prior to a release threshold. The binding is in communication with the boot heel and is adapted for slideable engagement in response to vertical and lateral forces exerted from the boot heel. The binding response tower adapted to disengage, or release upon reaching at least one a predetermined lateral displacement or a predetermined vertical displacement, such as when the boot heel is forced sufficiently sideways or upwards due to skier movement that would tend to cause an ACL injury.

Abstract: A prosthetic appliance disposes a plurality of elongated, resilient members in a circular configuration around a pivot point representing a skeletal joint such as an ankle, wrist or shoulder. The resilient members are resilient and adapted to deformable respond to pivoting forces of the fulcrum, and forcibly deform in response to the pivoting of the shaft forcing the fulcrum against the resilient members. The circular orientation of the resilient members pivot the shaft orthogonal to the base from which the resilient members extend, such that the resilient members bias the fulcrum and shaft in the orthogonal position at a rest position. Forces drawing the shaft off-center disposed the fulcrum against one or more of the resilient members and causing resilient deformation and counterforces against the fulcrum back to the centered rest position. In response to pivoting movement, the resilient members apply increasing forces for biasing the pivoting shaft.
