A power transmission apparatus includes a driving joint unit having a first driving gear fixed to a first driving shaft and a second driving gear fixed to a second driving shaft, an operating joint unit fixed on an operating shaft and having an operating gear rotating together with the operating shaft, a first operating belt connected to the first driving gear and the operating gear, a second operating belt connected to the second driving gear and the operating gear to apply a torque in opposite directions, a driving link having one end connected to the first driving shaft or the second driving shaft and the other end connected to the operating shaft, and an operating link fixed to the operating shaft.

A vision-assist device may include at least one image sensor for generating image data corresponding to an environment, a user input device for receiving user input regarding one or more physical characteristics of a user, and a processor. The processor may be programmed to receive the image data from the at least one image sensor, receive the user input from the user input device, and adjust an alignment of the at least one image sensor based on the received image data and the user input. Methods for aligning an image sensor are also provided.

Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.

A walking assistance device deformable based on a thigh shape includes a hip joint actuator, an upper thigh frame connected to the hip joint actuator and configured to receive power from the hip joint actuator and rotate about a first axis and rotate about a second axis intersecting the first axis, a motion frame connected to the upper thigh frame, the motion frame including a plurality of segment frames configured to rotate relative to each other, and a lower thigh frame connected to the motion frame.

An apparatus for screening, treatment, monitoring and/or assessment of visual impairments, comprising electronic means for simultaneously applying two separate and unrelated processing methods to images presented to a patient's eyes: a first processing method being applied to an non-amblyopic eye (the eye with the better vision), and a second processing method being applied to an amblyopic eye (the weaker eye, or the impaired eye). A method for screening, treatment, monitoring and/or assessment of visual impairments, comprising: a. defining a starting point, wherein differences between a patient's eyes are completely, or as closely as practically possible, corrected, to enable two identical or similar images to be transferred to the brain from the patient's eyes; b. defining an ending point, wherein there is no correction applied to any of the patient's eyes; c. defining a screening, treatment, monitoring and/or assessment plan, for initially applying correction to images according to the starting point, then gradually reducing the correction, at a controlled and predetermined rate, towards the ending point; and d. applying the plan to images presented to the patient's eyes, while monitoring patient's performance.

A load bearing assistance apparatus for transferring load from a lower extremity orthotic or prosthetic device to the ground. The load bearing assistance apparatus includes a lateral and a medial spring-loaded members and a linking mechanism for connecting the load bearing assistance apparatus to the lower extremity orthotic or prosthetic device. The linking mechanism also connects the lateral and medial spring-loaded members in a spaced apart configuration so as to position them adjacent the lateral and medial portions, respectively, of the foot of the user of the lower extremity orthotic or prosthetic device and such that a portion of the lateral and medial spring-loaded members enters in contact with the ground during locomotion.

A vision-assist device may include at least one image sensor for generating image data corresponding to an environment, a user input device for receiving user input regarding one or more physical characteristics of a user, and a processor. The processor may be programmed to receive the image data from the at least one image sensor, receive the user input from the user input device, and adjust an alignment of the at least one image sensor based on the received image data and the user input. Methods for aligning an image sensor are also provided.

A fitness garment that promotes excessive water weight and body fat loss at targeted areas of the wearer's body. The fitness garment is adjustable, machine washable, and conforms close to the user's body to specifically target problem weight loss areas to ensure maximum results. A lower panel formed of neoprene is held in close conformity to a user's torso to retain body heat at targeted locations. An upper panel is formed of a breathable resilient material and extends around the user's chest and shoulders, when worn. A zipper closure on a front face of the garment is operable to regulate the user's body heat. A lateral side zipper is provided as a closure of a side opening of the lower panel to selectively retain body heat around the user's stomach and back around the waistline.

A shorts-type pneumatic massage apparatus includes a shorts-pressurizing portion including a left shorts portion, which includes a plurality of air chambers extending in a longitudinal direction of the wearer's legs and which has a right side open from a top of a crotch, and a right shorts portion, which includes a plurality of longitudinal air chambers extending in the longitudinal direction of the wearer's legs and has a left side open from the top of the crotch, wherein the open right side of the left shorts portion and the open left side of the right shorts portion are coupled along an end; and an air injection adjustment portion configured to inject air to or discharge air from each of the longitudinal air chambers to allow the longitudinal air chambers to expand or contract.

The inventive concept relates to a wearable hand robot mounted on a finger to bend the finger by an external force transmitted through a wire. The wearable hand robot is capable of preventing an injury to a user's hand by the wire, achieving simplification of the structure of a finger cap and an improvement in a wearing sensation, and stably moving the finger while having a tactile sensation.
