The present disclosure provides generally for a particle guard system and apparatus. The system may comprise temples, shield, and nose bridge. A particle guard may prevent or limit aspiration from entering the user's external environment via shield that covers the nose and mouth. The particle guard may comprise interchangeable components for personalization and various utility. The temples and the nose bridge may be available in various colors and styles for customization of the particle guard. The particle guard may possess attachments for various utility. Temples may comprise integrated attachments. For example, temples may contain a wireless signal device for external communication. The particle guard may comprise a sanitation system. Where the system includes external covering, shield may interface with the external covering via opening in the external covering.

A collar sized to be worn around the neck of a human subject has at least one member that defines an arc of less than 360° and greater than 180° having a diameter, a first compressor at a first end of the arc, a second compressor at a second end of the arc and a bend angle sensor. The collar is adapted to exert an inwardly-directed force on the first and second compressors when worn. The bend angle sensor is configured and positioned to detect a bend angle of the collar, wherein the bend angle correlates to the inwardly-directed force on the first and second compressors when worn.

A back protection device for the practice of sporting activities includes a plate covering at least partially the surface of the back and in the thickness of which recesses are made intended to ensure the flexibility of the plate. The plate comprises a longitudinal ridge, the axis of which is intended to extend along the spine by delimiting, on either side, two right and left parts, each composed of an upper zone and a lower zone. The four zones are movable relative to each other, each being provided with recesses in the form of slots opening onto at least one face of the plate and being oriented with an inclination angle that is variable relative to the axis of the longitudinal ridge, so as to dissociate the flexibility of said zones.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for creating exosuit interfaces using 3D printing. One of the methods includes receiving a three-dimensional data model of one or more areas of a person's body; determining exosuit position data that identifies a portion of the three-dimensional data model for which an exosuit model will be generated; determining an actuator housing location to integrate an actuator housing in a component of the exosuit model, the actuator housing location being determined to align a first movement path for an actuator received in the actuator housing with a second movement path for the person's body; and generating at least a portion of an exosuit model that includes the component having (i) a region shaped to correspond to a contour of the person's body and (ii) an actuator housing at the actuator housing location.

The disclosure provides neck collar devices and systems for the mitigation and prevention of traumatic brain injury, including concussion. Specifically disclosed are adjustable collars and systems, and collars having certain pressure sensing devices.

A method for inhibiting fungal and bacterial infections of the foot enables a foot to be covered with a flexible, waterproof sheath while an upper region of the body is being washed. The sheath is donned on the foot before the upper region of the body is washed, so as to protect against carriers of the fungal contaminants, such as liquids, debris, and soap that flow towards the foot. The sheath is sufficiently sized and dimensioned, so as to snugly encapsulate the foot, and thereby inhibit moisture, soap, fungus, and bacterium that originate at the upper regions of the body from engaging the foot, anywhere from the ankle to the toes. The method enables the entirety of the foot to be covered with the sheath through a simple tugging motion. After washing the upper region of the body, the sheath is urged off the foot, and the foot is washed independently.

A protective garment system includes a garment base and at least one protective element that is removably engageable with the garment base. In some configurations, a first protective element comprises a plurality of attachment or anchor features that interact with the garment base or another portion of the system to partially or fully engage the first protective element in a removable manner with the garment base. In addition or in the alternative, the protective garment can include a second protective element that is removably engageable with the garment base separately from the first protective element. The protective elements can be a knee cap and a knee pad.

An insulating body wrap includes a superior end with a superior opening and an inferior end with an inferior opening. A top layer including a fabric extends between the superior opening and the inferior opening and a back layer including a ripstop material extends between the superior opening and the inferior opening. Batting is provided between the top layer and the back layer and a slit extends between the inferior opening and a point intermediate the inferior and superior openings. A method for manufacturing an insulating body wrap includes forming a quilt having a superior edge, an inferior edge, a first side edge and a second side edge and attaching the first and second side edges to form a sleeve having a superior opening and an inferior opening. A slit is formed extending between the inferior opening and a point intermediate the inferior and superior openings.

A protective pad assembly for removably positioning on an arm or a leg of a user of the protective pad assembly for protecting an elbow or a knee of the user. The protective pad assembly comprises an outer protective unit including a protective cushion pad configured to protect the elbow or the knee of the user from impact, and a self-retaining device mounted to the outer protective unit for retaining the outer protective unit on the arm or leg of the user. The self-retaining device includes a resilient retaining split-ring clamp having two opposite free ends spaced from one another. The free ends of the resilient retaining split-ring clamp are circumferentially expandable or contractable relative to one another for retaining the protective pad on an arm or a leg of the user of the protective pad assembly over one of the elbow and the knee thereof.
