The motion augmentation system including a plurality of cables operably coupling a body chassis to at least one sleeve assembly, each of the plurality of cables traversing through a corresponding one of a plurality of embedded lumens within the sleeve assembly and controlled by one or more corresponding cable actuators operably coupled to the body chassis, the corresponding cable actuators configured to selectively apply a force via the plurality of cables between the body chassis in the at least one sleeve assembly.

A device that uses an anatomic landmark or fiduciary point to establish a point of origin for device orientation in space is provided. The device controls the direction and depth of delivery of a needle, wire, trocar or cannula utilized for diagnostic or therapeutic intervention. The device guides the percutaneous delivery of a needle, wire, trocar or cannula to a target spatial location on or within tissue.

To provide a tapping device, capable of making a more comfortable tapping motion. A tapping device for vertically tapping a skin surface comprising: a tapping applicator for applying a normal force on the skin surface, wherein the tapping applicator is reciprocated in a direction perpendicular to the skin surface; an actuator for generating the linear reciprocating motion of the tapping applicator, wherein the actuator comprises a direct-current motor which is driven at an applied magnitude of voltage; a pressure sensing mechanism for measuring the magnitude of normal pressure exerted on the actuator during the operation of the tapping device in real time; and a controller for controlling the magnitude of voltage to be applied to the direct-current motor in real time, wherein the applied magnitude of voltage corresponds to the magnitude of normal pressure measured by the pressure sensing mechanism.

Adjustable seating devices for use in a hot tub may include multiple panels that move relative to one another and/or relative to the hot tub frame to adjust between positions. In some embodiments, one or more panels of the adjustable seating device may include jets. The adjustable seating devices may be adjusted manually, hydraulically, air-actuated, or electronically.

Systems and devices for assistive mobility are disclosed herein, e.g., for assisting those with reduced mobility to reduce energy used during gait and to reduce fatigue and loads on joints. In some embodiments, a walking assistive device, e.g., an exoskeleton, can be coupled to a user. The device can include a harness that can be coupled to a torso of the user and a support that can be coupled to a leg of the user. The device can also include an elastically deformable member that is coupled to the harness and the support that can expand during walking strides or other body movements to reduce muscle strain and augment the metabolic cost of walking. The elastically deformable member can store and release mechanical energy during phases of the gait cycle to provide additional torque to the biological torque generated at the hip joint.

A walking aid that assists a user in walking in an upright position. The walking aid may include a rear lower frame structure, a front lower frame structure, a first front wheel coupled to a first front lower frame member, a second front wheel coupled to a second front lower frame member, a first rear wheel coupled to the first rear lower frame member, a second rear wheel coupled to the second rear lower frame member, an upper frame structure comprising a first upper frame member, a second upper frame member, a first forearm support, and a second forearm support, a first pivot and latch mechanism pivotally coupling the first upper frame member and the first rear lower frame member together, and a second pivot and latch mechanism pivotally coupling the second upper frame member and the second rear lower frame member together.
