The disclosure features visual assistive devices that include a detection apparatus configured to receive information about an environment surrounding a user of the visual assistive device, a communication apparatus configured to transmit information to the user, and an electronic processor coupled to the detection apparatus and the communication apparatus, and configured to: receive information about an activity of the user; filter the information about the environment surrounding the user based on the activity of the user; assign a priority rank to each element of the filtered information based on the activity of the user; and transmit at least some of the elements of the filtered information, according to the assigned priority ranks, to the user using the communication apparatus.

A modular passive-to-active exoskeleton system utilizes motor unit modules, an electromagnetic-clutch power transmission system, and biometric control. The passive exoskeleton has a stamina-increasing chairless chair function and optional use of magnetic ball-and-socket joints and knee torsion springs. To convert the exoskeleton system into an active robotic wearable device, modular attachments allow for motor units to be securely connected to the exoskeletal frame. An exoskeleton system may contain a knee motor unit that has a transmission system with an electromagnetic clutch that enables a passive mode, active mode, and/or hybrid mode. The motor units are controlled using wireless biometric motion sensors that measure limb joint angle and muscle activity. These motor units also communicate via wireless transmission with a central processing unit of the exoskeleton. This central processing unit serves as a gateway for user feedback from an Internet-of-Things (IoT) device, such as a smartphone, tablet, computer, etc.

This present invention relates to an electric spine back pain relieving device. The device has a fixed frame that is configured to be integrated or retrofitted to backrest of a chair for providing support to spine of a user. The device has a frame and has an integrated electric source for providing mechanical pressure on facet joints or vertebras of spine of a human. The rigid frame carries a plurality of parallel rods attached to and crossing the space between the two longer arms of the frame. Each of the rod in the cervical, thoracic and lumbar regions carry a pair of barrel-shaped or spherical spindle nodules that are positioned below the transverse processes of the spine for alleviating pain. The electric source can be selectively activated using a push button and the device works on one of the two modes: single action mode and block action mode.

A therapeutic device includes flexible vibrating module with flexible radiating arms outwardly projecting around the module, with each arm having an associated coin motor which can optionally be operated at high frequency or low frequency or pulsing frequency. In addition to the vibratory elements of the device, a selective thermal element is included to provide heating and/or cooling for additional therapy. The heat, cooling, and/or vibrations can be used together or alone to provide therapeutic benefits to various body locations of a user. The device can be used with a wrap to hold the device in place for use.

An irradiation head adapted to be detachably attached to a massage gun, the irradiation head being configured to reciprocate in forward and backward motion, comprises one or more irradiation sources, and a converter configured to convert the forward and backward motion of the irradiation head into electrical energy. The one or more irradiation sources are configured to be activated by the converted electrical energy, wherein the converter includes a coil based linear alternator, the coil based linear alternator including, a coil wrapped around a hollow cylindrical body, and a magnet disposed within the hollow cylindrical body.

Devices, systems, and methods can be used to provide therapy to users and/or to monitor various physiological parameters of the user.

A handheld tool includes a handle; an implement mount configured to detachably accept and to rigidly hold a user-assistive implement; an actuator assembly mounted to the handle to physically manipulate the implement mount relative to the handle; a first sensor disposed to sense an orientation of the handle; a second sensor disposed to sense an orientation of the user-assistive implement; a controller disposed in or on the handle and coupled to the actuator assembly and the first and second sensors; and memory coupled to the controller. The memory stores instructions for identifying a type of the user-assistive implement attached to the implement mount, selecting a behavior routine based upon the type of the user-assistive implement identified, and manipulating the user-assistive implement relative to the handle according to the behavior routine to aid performance of a task with the handheld tool.

Devices and methods for assisting and guiding a person with visual and/or hearing impairment. In various embodiments there is a computer-guided, motorized walking stick. Preferably, at least one wheel at the distal end of the stick, and in contact with the ground, can be steered or pivoted over a range of angles, and thus establish a desired direction. In yet other embodiments there are one or more powered wheels that further drive the walking stick in the desired direction. Various algorithms are disclosed for providing instructions to the computer controller by way of various input devices. Still further embodiments include various types of sensors that provide data to the computer with regards to objects proximate to the walking stick.
