A powered orthotic device for use with a limb having at least two joints includes at least two brace sub-assemblies. The first brace sub-assembly includes a first powered actuator assembly that receives a first sensor signal from a sensor selected from a group consisting of an electromyographic sensor, an inertial measurement unit, and combinations thereof. The first powered actuator assembly applies a first force for driving sections positioned with respect to a first joint to move relative to one another. The second brace sub-assembly includes a second powered actuator assembly that is configured to receive a second sensor signal from a sensor selected from a group consisting of an electromyographic sensor, an inertial measurement unit, and combinations thereof. The second powered actuator assembly applies a second force for driving sections positioned with respect to a second joint to move relative to one another. The first force and the second force are based on the first sensor signal or the second sensor signal.

Powered orthotic device and method of using same

A powered orthotic device includes a brace, a finger engagement member, a thumb engagement member, and a hand actuator. The powered orthotic device includes a locking mechanism affixed to the brace, and a finger carrier assembly with a finger carrier to engage the fingers of the wearer, as well as an affixment member configured to be removably attached to the locking mechanism. The wearer dons the orthotic device, without assistance from another, by placing the set of fingers into the finger carrier and using a free hand of the wearer to affix the affixment member to the locking mechanism.

Self-donning powered orthotic device

A multi-layer, super-planar laminate structure can be formed from distinctly patterned layers. The layers in the structure can include at least one rigid layer and at least one flexible layer; the rigid layer includes a plurality of rigid segments, and the flexible layer can extend between the rigid segments to serve as a joint. The layers are then stacked and bonded at selected locations to form a laminate structure with inter-layer bonds, and the laminate structure is flexed at the flexible layer between rigid segments to produce an expanded three-dimensional structure, wherein the layers are joined at the selected bonding locations and separated at other locations. A layer with electrical wiring can be included in the structure for delivering electric current to devices on or in the laminate structure.

Pop-up laminate structures with integrated electronics

A powered orthotic device for use with a limb having at least two joints includes at least two brace sub-assemblies. The first brace sub-assembly includes a first powered actuator assembly that receives a first sensor signal from an electromyographic sensor. The first powered actuator assembly applies a first force for driving sections positioned with respect to a first joint to move relative to one another. The second brace sub-assembly includes a second powered actuator assembly that is configured to receive a second sensor signal from a sensor selected from a group consisting of an electromyographic sensor, an inertial measurement unit, and combinations thereof. The second powered actuator assembly applies a second force for driving sections positioned with respect to a second joint to move relative to one another. The second force is based on the first sensor signal or the second sensor signal.

The present invention is directed to a bi-stable coupling for controlling the depth of a tool insertion, such as drilling, and similar processes. The bi-stable coupling can be used to penetrate (e.g., drill or push) through a material layer of unknown thickness without plunging the tool into the adjacent layer. In accordance with the invention, in a first state, force is applied to the tool to initiate penetration and a reactive force maintains the device in the first state during penetration and when tool penetrates the material, the reactive force is diminished enabling the device to transition to a second state in which the tool becomes retracted. In medical applications, the invention allows for drilling through bone of unknown thickness without plunging into the adjacent soft tissue.
