    摘要: A system or method for measuring human ocular performance can be implemented using an eye sensor, a head orientation sensor, and an electronic circuit. The device is configured for measuring vestibulo-ocular reflex, pupillometry, saccades, visual pursuit tracking, vergence, eyelid closure, dynamic visual acuity, retinal image stability, foveal fixation stability, focused position of the eyes or visual fixation of the eyes at any given moment and nystagmus. The eye sensor comprises a video camera that senses vertical movement and horizontal movement of at least one eye. The head orientation sensor senses pitch and yaw in the range of frequencies between 0.01 Hertz and 15 Hertz. The system is implemented as part of an impact reduction helmet that comprises an inner frame having interior pads configured to rest against a person's head and one or more shock absorption elements attached between the inner frame and the spherical shell that couple the spherical shell to the inner frame. The spherical shell has a circular geometry, that when viewed horizontally at its horizontal midplane, includes a center point that is the rotational center of the spherical shell. The one or more shock absorption elements are sized to provide greater spacing between the inner frame and the spherical shell at the sides and rear of the spherical shell than at the front of the spherical shell. The one or more shock absorption elements are sized to configure the alignment of the rotational center of the spherical shell with the proximate rotational center of the wearer's head.

    摘要: A system and/or method for measuring a human ocular parameter comprises a human-wearable face shield which has an eye sensor, a head orientation sensor, and an electronic circuit, and a face shield. The eye sensor comprises a video camera that measures horizontal eye movement, vertical eye movement, pupillometry, and/or eyelid movement. The head orientation sensor measures pitch and/or yaw of the wearer's face. The electronic circuit is response to the eye sensor and the head orientation sensor and measures an ocular parameter such as vestibulo-ocular reflex, ocular saccades, pupillometry, pursuit tracking during visual pursuit, vergence, eye closure, focused position of the eyes, dynamic visual acuity, kinetic visual acuity, virtual retinal stability, retinal image stability, foveal fixation stability, or nystagmus.

    摘要: A non-electronic head-worn system for providing visual inertial head orientation information to a person is disclosed. The system comprises a head-worn unit that displays at least one orientation reference symbol to the person wearing the unit wherein the orientation reference symbol stays in a fixed visual position for the person when the person's head changes orientation. The system also comprises a pitch indicator that gives visual pitch information to the person and a roll indicator that gives visual roll information to the person. The pitch indicator and the roll indicator are responsive to a pendulum, a rolling element, or a fluid in a reservoir. The pitch element and the roll element do not use electricity or electronics.

    摘要: A system and/or method for determining human health uses a head-worn apparatus that comprises a head orientation sensor, an eye imaging device, and an electronic circuit. The head orientation sensor is configured for generating an electrical head orientation signal in response to head pitch or head yaw. The eye imaging device is configured for observing an eye feature from the sclera, cornea, iris, or pupil, and generates an eye electrical signal in response to eye position, horizontal eye movement, vertical eye movement, pupil size or eyeblinks at a plurality of times. The electronic circuit is configured for generating an ocular parameter measurement such as saccades, vestibulo-ocular reflex, vestibulo-ocular reflex cancellation, vergence, smooth pursuit, nystagmus, dynamic visual acuity, pupil size, and/or eyeblinks from the head and eye electrical signals. The ocular parameter measurement can be used to determine normal human health, a neurologic disorder, a biochemical health impairment, or a physiologic health impairment.

    摘要: An impact reduction helmet and method are disclosed. The helmet and method include an inner frame having interior pads that rest on a person's head and a second frame coupled to the first frame with shock absorbers wherein the shock absorbers are larger in the section of the helmet near the rear of the helmet and shorter in the section closer to the front of the helmet in order to move the rotational center of the helmet closer to the rotational center of the head. The first frame and second frame are also spaced farther apart than prior art helmets to increase the distance available for impact absorption.

    摘要: A wearable impact reduction device including a first layer, a second layer, a third layer, and a fourth layer. The first layer is located closest to the wearer's body and includes a flexible material configured to conform to the shape of a user's body. The fourth layer is located furthest from the wearer's body and is more rigid than the first layer whereby the fourth layer can distribute an external impact over a region. The second layer is placed between the first layer and the third layer. The third layer is placed between the second layer and the fourth layer. The second layer includes an elastically-deformable material having at least one resilient impression arranged and configured to at least partially compress upon application of a force and to return elastically to its original shape upon removal of the force. The third layer comprises an elastically-deformable material having at least one resilient impression arranged and configured to: contact and transmit a force to said resilient impression in the second layer, at least partially compress upon application of a force, and return to its original shape upon removal of a force.
