A portable system and method for training an alternate retinal location of a viewer's eye with impaired retina and an assistance system for improving vision of such viewer's eye are disclosed. The portable system for training comprises an eye tracking module to provide eye information of the viewer's eye and a virtual image display module to display a virtual image centered at the alternate retinal location on the viewer's impaired retina other than centered at a fovea. The virtual image display module further comprises a first light signal generator to generate multiple first light signals and a first combiner to redirect the multiple first light signals towards the alternate retinal location, when a pupil of the viewer's eye is located approximately at the center of the viewer's eye.

A novel structural inversion table includes a body including a back plate, a headrest and a tripod rotationally connected with a cross brace at middle. Air holes are penetrated through the back plate. Two T-shaped guide rods are disposed on the cross brace of the tripod and having one ends provided with fixed bars that are fixed on a side wall of the back plate by screws, the T-shaped guide rod is sleeved with a return spring outside and is connected with a base plate having a hollow structure. Water outlet tubes are disposed at a side of the base plate contacting the back plate. A stroke conversion mechanism is disposed between the base plate and the cross brace. The present invention relates to fitness equipment, the inversion table can effectively improve the air permeability of the back plate as well as safety, to ensure the experience of the exerciser.

A system can include a base configured to support a lower half of a human body. The system can also include a headrest elevated relative to the base, wherein the headrest is disposed adjacent to a proximal end of the base, where the headrest is configured to support a head of the human body. The system can further include a back platform having a first end and a second end, where the first end is coupled to the base, where the second end is disposed adjacent to the headrest, and where the back platform has a curvature, where the back platform is configured to support a torso of the human body. The system can also include a vibrating mechanism in communication with the back platform, where vibrations generated by the vibrating mechanism translate to the back platform.

Disclosed is an eye training system (10) including a head-mountable computing device (100) comprising at least one display module (106, 106′) arranged to be viewed by the wearer of the head-mountable computing device when wearing the device; and a display processor (108) coupled to the at least one display module for controlling the at least one display module and adapted to display an initial set of eye exercises on the at least one display module; a sensor arrangement (120) for monitoring eye responses of the wearer to the displayed initial set of eye exercises; and a data processor (110) adapted to receive eye response data from the sensor arrangement and to process the eye response data; wherein the display processor is further adapted to display a subsequent set of eye exercises on the at least one display module in response to a processing result of the processed eye response data. A computer program product is also disclosed.

A manual ear pump including one or more of a support element configured to releasably engage an external ear canal and having an interior chamber, a resilient element capable of being resiliently deformed coupled to a support element, and an aperture disposed on a support element bottom surface communicating with the external ear canal and interior chamber.

The present disclosure is applicable to the technical field of massage apparatuses, and provides an electric massage cap, including a cap body, a liner, a massage unit, a vibration source, a control unit and a battery pack; the liner, the massage unit, and the vibration source are all mounted in the cap body; the massage unit made of an elastic retractable material and shaped like a convex contact is arranged on the liner and is in contact with the head of a user; the vibration source is mounted in the massage unit; vibration energy generated by the vibration source is converted into swing and touch energy through the massage unit to massage the head of the user in a vibrating, stroking and finger-pressing manner; the control unit is connected to the vibration source and battery pack respectively; and the vibration source is controlled to vibrate by control unit.

An emergency management system having an ice water immersion bag capable of rapidly cooling an overheated individual's body through its combination of elements, apertures, and capacity. An overheated individual is placed within the ice immersion bag, yet the individual's body may still be accessed in the event of a medical emergency through the use of one of the many openings presented throughout the bag. The openings otherwise remain sealed and waterproof to prevent the ice water from escaping the bag, further effectuating ice water immersion to rapidly cool the overheated individual.

The technical description relates to a vestibular optimizer device configured to administer vestibular stimulation to a subject having a head. An example vestibular optimizer device includes a chair having a base, a seat, a back, and a support member, the support member extending from the base to the seat, having a central longitudinal axis, and being attached to the seat, the support member rotatable about the central longitudinal axis, the seat adapted to move toward and away from the base, the chair adapted to move in a first pattern of movements. It also includes a head engaging member attached to the back of the chair and configured to engage the head of the subject, the head engaging member adapted to move in a second pattern of movements.

A cervical traction device is provided. A frame presents an anterior support under the maxilla of a user, while a posterior support is applied to the lower portion of the occiput of the user. Thus, pressure is avoided on the potentially unstable mandible, and the lower and upper teeth are not compressed against one another. A series of suspension points on the frame allows the angle at which traction may be applied to the cervical vertebrae to be varied.

A three-dimensional spine correction robot includes: a pillar, a seat, human body fixing belts, a head fixing apparatus, a bracket, pillar casing pipes, a spine lateral push-and-pull apparatus and a seat locking mechanism. The head fixing apparatus is fixed on the top of the bracket. The pillar casing pipes are movably sleeved over the pillar, and each pillar casing pipe is connected to a human body fixing belt. The lower end of the pillar casing pipe is connected to the seat, and the upper end is connected to the pillar. A first elastic connection object is connected between the pillar casing pipes. The spine lateral push-and-pull apparatus may move up and down along the pillar and swing. The seat is connected to the pillar through a bearing, and may move up and down along the pillar. The seat locking mechanism is fixed between the bracket and the seat.
