A shock absorber includes a bottom rim, a top wall comprising a raised central portion and a top rim, a side wall extending between the top and bottom rims, and a corrugation surrounding a periphery of the raised central portion that (i) connects the raised central portion to the top rim, (ii) descends to a depth below half a height of the side wall, and (iii) is separated by a distance from a surface. Impact forces imparted on the shock absorber are attenuated by a first amount in a first stage by resistive yielding of the side wall; by a second amount in a second stage by depression of the central portion and resistive yielding of the corrugation associated therewith; and by a third amount in a third stage by resistive yielding of the corrugation in response to a force applied to the top rim upon contact with the surface.

The present invention is a helmet system that reduces concussions by damping rotational forces transmitted to a helmet wearer's head. The helmet has an exterior shell with an internal side that has impact absorption apparatus attached. The helmet also has an internal body worn close to the wearer's head. A gap between the internal body and the impact absorption apparatus close to the shell is maintained with flexible projections. At least one magnet assembly is located with the exterior shell absorption apparatus, with a magnetic pole extending axially inwards, and at least one magnet array is located with the internal body, with the same magnetic pole extending axially outwards. Each internal body magnetic field is axially aligned with a magnetic field of a respective magnet assembly located with the exterior shell absorption apparatus. In a resting state the aligned magnetic fields have little magnetic interaction. The internal body, in contact with the player's head, moves independently from the exterior shell; in one embodiment the internal body moves freely on a skeletal structure. When the wearer's helmet collides with another object, the wearer's head drives the internal body out, and the collision object drives the exterior shell absorption apparatus in. Magnetic repulsion increases. When the collision is tangential, the exterior shell magnet assembly is offset from axial alignment with the internal body, and the magnet array with the internal body torques, so the internal body resists rotational movement, or the internal body moves in the opposite direction of the exterior shell rotation vector. This dampens transmission of rotational forces to the wearer's head. In one embodiment sensors on the internal body detect and send magnetic field acceleration data to a controller, and if the shell's rotation is above a threshold acceleration, the controller inflates an airbag around a user's neck and head to inflate and keep the user's head from moving.

A clip for a hard hat includes a body having a first end and a second end opposite the first end, a plurality of longitudinally extending fingers formed in the body, and a plurality of slots formed in the body to separate the plurality of longitudinally extending fingers. The plurality of slots is in communication with openings at the second end of the body. The plurality of slots is configured to receive a strap. The clip further includes a hook portion formed in the body at the second end of the body for removably coupling the clip to the hard hat. The hook portion curves toward the first end of the body.

The present invention relates to a light apparatus for headwear including an at least partially hollow, elongate housing for mounting to the headwear, at least one light located inside the elongate housing that is visible from the outside of the elongate housing, and at least one battery for powering the at least one light, such that when the light apparatus is mounted to the headwear, an orientation of the headwear can be determined.

A safety helmet with light-emitting system. The light-emitting system includes a light-emitting device and battery holder. The light-emitting system is fastened within a cavity of the helmet shell, configured for receiving the light-emitting system. The safety helmet with light-emitting system when turned on illuminates providing visibility while also alerting fellow workers and pedestrians nearby of a user's position.

The present invention relates to a helmet that includes an outer shell, a heads-up information system that comprises a display, and an attachment assembly. The heads-up information system is movable from a storage position within the outer shell to a use position in which the display of the heads-up information system is visible by a user, without obstructing the field of vision of the user, when the helmet is worn by the user. The attachment assembly is coupled to outer shell and the heads-up information system, and is operable to move the heads-up information system between the storage position and the use position.

The present invention is directed to a helmet wearing determination system including a imaging means that is installed in a predetermined position and images a two-wheel vehicle that travels on a road; and a helmet wearing determination means that processes an image imaged by the imaging means, estimates a rider head region corresponding to a head of a person who rides on the two-wheel vehicle that travels on the road, compares image characteristics of the rider head region with image characteristics according to the head at a time when a helmet is worn or/and at a time when a helmet is not worn, and determines whether or not the rider wears the helmet.

A safety integrated electrically powered vehicle (SIPV) apparatus comprising an electric vehicle further comprising at least an integrated safety control apparatus wherein the integrated safety control apparatus polls a plurality of sensors to detect current SIPV data related to safe use, a communication link to an integrated safety control apparatus to transmit a plurality of data representative of the current use of a SIPV, and receive from the SIPV system at least an instruction received from the integrated safety control apparatus via the communication link to direct a plurality of control units on the SIPV to modify current operation parameters to bring the SIPV back to a safe use.

A ballistic helmet comprising a ballistic shell, wherein within the thickness of the ballistic shell, or inside the ballistic shell, there is provided one or more circuit layers forming a circuit, which circuit comprises a power bus and a data bus, and wherein one or more power connections and one or more data connections are provided on the inside and/or on an edge of the ballistic shell for providing power and data to/from one or more electrical devices through the circuit.

Low profile concavely curved cameras, camera housings and related systems and methods. These devices, etc., simultaneously reduce snags and other hazards and also provide improved protection to people such as military and first-responder personnel and athletes by improving the attachment of the camera housing to a helmet or other complexly curved convexly curved base substrate.
