Virtual Body-Weight Support via Lower-Limb Exoskeleton

Summary:This is a novel control system for powered lower-limb exoskeletons (or orthoses) that provides body-weight support (BWS) for people who have sustained a stroke and other neurological injury. Patients are provided with BWS during conventional gait retraining to help them produce the coordinated muscle activities needed for walking. Although current...

Neurocase: Peripheral Nerve Electrode for Neural Recording and Stimulation

The ability to record and stimulate neural activity with implanted microelectrode arrays has been limited by the problems of insertion trauma and foreign body response, which can lead to neuron damage and reduced reliability of results. Minimizing such tissue responses is necessary to develop implantable interfaces for studying neural activity and even...

Method for Measuring Carbon Nanotubes Taken-Up by a Plurality of Living Cells

Carbon nanomaterials (CNMs), including carbon nanotubes (CNTs) and graphene, are undergoing extensive research due to their diverse commercial applications and potential for biomedical uses. The global increase in the production of CNMs and incorporation into consumer products is cause for concern because of the consistent reports that CNMs can be toxic....

Unified Lower-Limb Prosthetic Control Strategy

Non-Confidential Description: This technology defines a novel control strategy for a powered prosthetic leg that unifies the entire gait cycle, eliminating the need to switch between controllers during different periods of gait. Current control methods divide the gait cycle into several sequential periods with independent controllers, resulting...
