A helmet includes interconnected flexing panels and a multi-chamber impact absorption system comprising a bladder including a plurality of adjacent compressible fluid filled chambers.

A helmet configured to protect a human head against mild traumatic brain injury upon impact includes an outer shell and a liner consisting of fluid fillable flexible fluid chambers fluidly connected to each other by fluid connections. The fluid chambers being spaced around the circumference of the helmet and configured to fill a space between the head and the outer shell when the helmet is positioned on the head. Impact resistant flexible pads are also in the liner and are spaced around an inner circumference of the outer shell adjacent to each of the fluid fillable flexible fluid chambers. A flexible inner shell inside the liner is configured to fit closely on the head. The flexible fluid chambers are configured to compress in response to impacting of the helmet on an impact side and to force liquids through the fluid connections to inflate other fluid chambers inside the helmet thereby cushioning the head against a rebound impact on the inside of the helmet.

A cardiorespiratory fitness optimizer apparatus includes a mouthpiece and a valve assembly. The mouthpiece includes lower and upper tooth beds and an anterior manifold. The manifold terminates anteriorly at a centralized valve assembly interface and includes at least one air-letting aperture. The valve assembly is matable with the centralized valve assembly interface and includes an adjustable aperture. The user is able to adjust the aperture for increasing and decreasing airflow resistance therethrough for optimizing cardiorespiratory fitness. The cardiorespiratory fitness optimizer apparatus may include at least one sensor for sensing airflow activity within the valve assembly and communicating data relating to the airflow activity to an external device for displaying human readable output relating to the airflow activity upon the external device. The valve assembly is removable from the mouthpiece and replaceable with a plug element for maintaining anterior formations of the mouthpiece when the valve assembly is removed.

The present disclosure relates to a personal wearable device. The personal wearable device may include one or more sensors, a charging circuit and a transceiver. In one embodiment, the personal wearable device may be a mouthguard. Also disclosed is a system which includes a personal wearable device and a personal electronic device which receives impact information from the personal wearable device, determines that the impact information indicates that an impact force above a pre-determined threshold has been experienced by the personal wearable device, and transmits a notification.

An article of weightlifting equipment includes a weightlifting jacket having a main vest-shaped body having a front covering the torso of a user, a back connected to the front, and one or more pads that provide a cushion to provide comfort and to protect the user from injury by reducing the force on the body caused by a barbell. The pads include a front pad that is positioned on the portion of the jacket front to cover the lower torso of a user wearing the weightlifting jacket. The jacket also includes one or more adjustable straps that allow the jacket to be fitted for users of different sizes. The equipment can have other forms, such as a belt instead of a jacket for positioning the torso pad.

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.

A pitching screen assembly adapted to be readily converted between a deployed configuration and a non-deployed configuration including: a first ground-engaging support member having a first end, a second end, and a midpoint, wherein the first end and the second end define a length therebetween; a second ground-engaging support member having a first end, a second end, and a midpoint, wherein the first end and the second end define a length therebetween; a frame sub-assembly having an internal aperture contained therein; a protective screen, wherein the protective screen covers at least a portion of the internal aperture of the frame sub-assembly; wherein the frame sub-assembly is associated with the first ground-engaging support member and the second ground-engaging support member; and wherein the frame sub-assembly is rotatably displaceable along a first axis (X) that is generally orthogonal to the length of the first ground-engaging support member and the length of the second ground-engaging support member.

A mouthpiece includes a first body configured to be secured over one or more teeth of a user. The first body comprises a frame for location about at least one of a molar or a premolar of user, as a first bite pad between upper teeth and lower teeth. The first bite pad is molded in the frame while in situ in the mouth of the user and the first bite pad is formed by a PVS material. The first bite pad is in contact with at least one of a molar or a premolar of user, and the first bite pad defines an exterior shape of at least a portion of the teeth of a user. There is a similar second body with a connector between the first body and the second body and together these form the appliance for the user.

A system, method, and blocking pad for receiving strikes from a special individual. The blocking pad includes a pad configured to receive the blows from the special individual. The blocking pad further includes a number of handles connected to a back of the pad. The number of handles include at least two handles in a middle portion of the back of the pad and at least a handle at ends of the pad.
