A walker with an automated power drive system is disclosed. The walker comprises a rigid frame comprising a left grip and a right grip; a plurality of wheels affixed to the rigid frame; a plurality of drive motors integrally mounted in the plurality of wheels; and a drive motor controller configured to power the plurality of drive motors. The drive motor controller is configured to: determine the orientation of the walker; generate a first motor current component to compensate for orientation of the walker and the resulting torque on the drive motor; determine the speed of the walker, generate a second motor current to component for internal friction based on the speed of the walker; determine a user force applied to the left grip and right grip; generate a third motor current component for the drive motors based on the user force applied to the left grip and right grip; and power the drive motors based on a sum of the first motor current component, second motor current component, and third motor current component. The drive motor controller is configured to determine the user force applied to the left grip and right grip based on a measured current from the drive motors. Specifically, the drive motor controller is configured to determine the user force applied to the left grip and right grip based on a difference between a target current provided to the drive motors and the actual current utilized by the drive motors.

A garment provides therapeutic pressure to the body of a wearer in response to a two-factor authentication system. The garment includes reversibly inflatable chambers configured to press against the body of a wearer. The garment includes a pump fluidly connected to the chambers and a controller. The controller sends an inflation signal to the pump to inflate the chambers and a deflation signal to the pump to deflate the chambers. The garment includes touch-sensitive fabric. In some implementations, the controller sends the inflation signal to the pump in response to one or more touches to the touch responsive fabric. In some implementations, the controller sends the inflation signal to the pump in response to biometric data.

The stick body includes a cover assembly, an end cover connected to the cover assembly, and a temperature transmitting member. The end cover includes a negative pressure connection hole. The temperature transmission member includes a suction port. The stick body further includes an air pipe communicates with the negative pressure connection hole and the suction port. The refrigeration module arranged inside of the stick body. The refrigeration module including a thermoelectric cooling chip and a heat sink. The thermoelectric cooling chip including a cold end and a hot end. The cold end attached to the temperature transmitting member. The hot end thermally contacts with the heat sink.

A powered mobility device comprises two powered wheels, a controller, and a control handle configured to generate control signals in response to being operated by push and pull inputs from a user. The control handle rotates between a first operating position and a second operating position such than an orientation of the control handle is reversed with respect to a forward movement direction of the mobility device. The controller is configured to control the powered wheels of the mobility device to move in the forward movement direction in response the control handle being operated in the forward movement direction and move in a reverse movement direction in response to the control handle being operated in the reverse movement direction in both the first operating position and the second operating position regardless of the reversed orientation of the control handle.

A rollator for mobility assistance to a user is provided. The rollator includes a chassis foldable in a compacted configuration, wheels rotatably mounted to the chassis, wheel braking assemblies engageable with the wheels, and a pair of handgrips mountable to the chassis and operatively connected to the chassis. Both handgrips have to be configured in a handgrip displacement configuration to configure the wheel braking assemblies into a displacement configuration of the wheels and wherein both wheel braking assemblies are simultaneously in the displacement configuration. The rollator can include a seat assembly which can be configured in a raised configuration and a seated configuration. In the seated configuration, a pressure equal to or greater than a seat pressure threshold has to be applied on the seat for the wheel braking assemblies to be configured in the displacement configuration.

The method for controlling a single- or multi-powered robotic system, such as an exoskeleton, a prosthesis or a collaborative robot, that is physically interacting with a user, said system comprising at least one actuated joint; wherein the robot joint(s) is/are controlled in force by a low level controller using an impedance control; wherein the joint(s) output force(s) is/are determined by a high level controller using a finite state control; and wherein the high level controller finite state control is governed by a voluntary motion from the user reaching a predetermined trigger.

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.

The invention provides a sensing control method and apparatus, and a vibration massage apparatus. The method includes: arranging a sensor which senses a trajectory of an external object, and controlling the change of output based on the direction of the trajectory. With the invention, a desirable control effect can be obtained based on the sensed direction of the trajectory of the external object without accurate positioning of the sensor. Not only the convenience of the sensing operation can be improved significantly, but also the control accuracy can be improved; meanwhile, the invention can be well applied to any device for control using several input control signals or variable input control signals for control, thus having a wide range of application and significantly optimizing user experience.
