A composite material which is elastic, which exhibits a resistive load under deformation which increases with the rate of deformation, which is unfoamed or foamed, comminuted or uncomminuted and which comprises i) a first polymer-based elastic material and ii) a second polymer-based material, different from i), which exhibits dilatancy in the absence of i) wherein ii) is entrapped in a solid matrix of i), the composite material being unfoamed or, when foamed, preparable by incorporating ii) with i) prior to foaming.

A system including a motorized base unit with a smart device mount for automatically orienting the smart device camera toward a moving target to track the moving target and take pictures or video. The target (e.g., a child playing soccer) wears a tracking tag comprising a GPS chip and transmitter packaged inside an athletic pad. The base unit includes a motorized mast for mounting a smart device. The base unit receives the transmitted GPS data, calculates updated pointing angle and angular velocity for the smart phone based on update location information from the remote tag sensor, calculates the correct angle that the smart phone should be pointed at, translates the new pointing directions to a control signal that turns the mast, which in turn causes the smart device camera to “follow” or track the target.

A mouthguard mounting, comprising a mount adapted for fixed attachment to a helmet; and a tether attached to the mount with a limited range of motion relative to the faceguard is disclosed.

A shock absorbing system for impact energy dissipation employs removable unitary cells of compressible members in communication with a reservoir and containing a first working fluid. Resilient structural members may be placed intermediate the compressible members to deform responsive to compression to provide both energy dissipation and resilient recovery of the compression cylinders to their uncompressed state.

A mouth guard, or wearable device, senses impact forces, calculates risk factors for injury, and displays status of risk and potential injury. A mouth guard may be used to identify, treat and prevent exacerbating brain injury. A wearable device can be programmed with biometric data to better calculate and anticipate impact thresholds and more precisely predict and prevent injury.

Methods and systems are provided for diagnosing and generating a treatment plan for temporomandibular joint dysfunction where a polymeric shell appliance is utilized to generate one or more activation forces that facilitate tooth movement. The polymeric shell appliances may comprise one or more tooth receiving cavities, in which each of the plurality of tooth receiving cavities is shaped and arranged to provide a counter moment of each of the plurality of teeth.

An oral appliance for treating sleep apnea in a user includes a mouthpiece configured for being positioned in an oral cavity of the user, and at least one pulse oximeter attached to the mouthpiece. According to an aspect, the pulse oximeter is configured to monitor actual oxygen saturation levels of hemoglobin of the user when the oral appliance is positioned in the oral cavity of the user. The oral appliance may include an additional sensor attached to the mouthpiece that includes at least one of an airflow sensor, a pressure sensor, a noise detector, and an actigraphy sensor.

An article of athletic gear, such as an article of protective athletic equipment (e.g., a leg pad, an arm pad, shoulder pads, a chest protector, or a protective glove), wearable by a user and comprising a core (e.g., comprising protective padding) and a cover that is disposed on the core and comprises synthetic material and a printed image (e.g., a digitally-printed image) on the synthetic material.
