One aspect of the present disclosure relates to a method for controlling levels of perceived intensity of a sensory stimulus. The method includes configuring a stimulation signal with an activation charge rate (ACR) based on a predefined level of intensity by a subject during an action. The ACR is based on a strength of pulses in the stimulation signal parameter and a frequency of pulses in the stimulation signal parameter. The stimulation signal can be applied to neural tissue of a subject during the action. Based on the stimulation signal, the subject can be induced to perceive the predefined level of intensity during the action.

Systems and methods for controlling levels of perceived intensity of a sensory stimulus

One aspect of the present disclosure relates to a system that can modulate the intensity of a neural stimulation signal over time. A pulse generator can be configured to generate a stimulation signal for application to neural tissue of an individual and modulate a parameter related to intensity of a pattern of pulses of the stimulation signal over time. An electrode can be coupled to the pulse generator and configured to apply the stimulation signal to the neural tissue. A population of axons in the neural tissue can be recruited with each pulse of the stimulation signal.

Patterned stimulation intensity for neural stimulation

A user-specific model of muscular activity can be used to control an external device based on muscular activity within a limb of a user. The user-specific model of muscular activity can include single movements and corresponding one or more primary muscle patterns. New single movements can be added to the user-specific model of muscular activity can be by a system that includes a processor by receiving user-specific EMG signals (including one or more EMG patterns that indicate a single movement); decomposing the user-specific EMG signals into the one or more EMG patterns in EMG feature space that indicate the single movement; and updating the user-specific model of muscular activity to include the single movement and corresponding one or more primary muscle patterns based on the one or more EMG patterns in EMG feature space.

A modular bumper attachment system configured to be attached or mounted to the bumper of a vehicle or base member. The modular bumper attachment system may include a first attachment member and a second attachment member, each attachment member an aperture defined by an outer wall that is configured to encompass the bumper of a vehicle. The system may also include one or more support members that are integrally attached to the attachment member. The support member may have a first end and a second end, wherein the first end is located where the support member meets the attachment member. The second end of each support member may extend at a non-zero angle in a generally outward direction from the base member and include one or more connectors configured to removably attach a hammock, tent, awning, storage container, cooler, etc. to the support member.

Modular bumper attachment

A system for functional electrical stimulation can include a cuff and a stimulation device. The cuff can be attachable to a nerve or a muscle filament. The cuff can include an elastic collar configured to exert a force on the nerve or the muscle filament to reshape the nerve or the muscle filament to the internal configuration of an opening in the elastic collar. The stimulation device can be coupled to the cuff and configured to provide a stimulation waveform to the cuff.

A hybrid method is provided for modulating upper airway function in a subject. The method includes applying first and second therapy signals to the subject to modulate at least one extrinsic laryngeal muscle and at least one intrinsic laryngeal muscle to synergistically control laryngeal motion and vocal fold movement, respectively.

A cap provided for use in capping a sewage drain tube of a vehicle and/or opening where a sewage drain tube is located. The sewer drain cap includes a chamber with a lid, useful for storage. Apertures to allow air flow or ventilation and to aid in removal and replacement of the sewer drain cap are provided. A sealing member for the drain tube cap is also provided for attaching to and/or sealing a drain tube and/or opening where a sewage drain tube is located.

The present invention relates a system that can configure a stimulus for functional electrical stimulation ('FES') to maintain a constant muscle force while delaying the onset of muscle fatigue and a related method of use. The stimulus can be delivered to a nerve via a set of multiple electrode contacts according to a stimulation parameter that maximizes a joint moment associated with the stimulus and minimizes the overlap between pairs of contacts. The joint moment can be related to the muscle force, and the overlap can be related to the onset of muscle fatigue.
