A device is provided for the stimulation of neurons that includes a non-invasive stimulation unit to generate stimuli in multiple stimulation channels, where the stimulation unit stimulates a neuron population in the brain and/or spinal cord of a patient in different locations for each of the stimulation channels. Moreover, the device includes a control unit that controls the stimulation unit to generate repetitive bursts in each of the stimulation channels, where each of the bursts includes multiple stimuli and is designed so that they do not reset the phase of the neuronal activity of the respective stimulated neurons.

Sensing devices including sensors such as flexible and stretchable fabric-based pressure sensors, may be associated with or incorporated in garments, such as socks, intended to be worn against a body surface (directly or indirectly). Specific manifestations of a sensing system incorporated in a sock substrate are described in detail. Dedicated electronic devices interface electrically with sensors through intermediate conductive traces, optional conductive bridges, conductive contacts provided in a mounting tab.

In one embodiment, a cognitive load driving assistant increases driving safety based on cognitive loads. In operation, the cognitive load driving assistant computes a current cognitive load of a driver based on sensor data. If the current cognitive load exceeds a threshold cognitive load, then the cognitive load driving assistant modifies the driving environment to reduce the cognitive load required to perform the primary driving task and/secondary task(s), such as texting via a cellular phone. The cognitive load driving assistant may modify the driving environment indirectly via sensory feedback to the driver or directly through reducing the complexity of the primary driving task and/or secondary tasks. In particular, if the driver is exhibiting elevated cognitive loads typically associated with distracted driving, then the cognitive load driving assistant modifies the driving environment to allow the driver to devote appropriate mental resources to the primary driving task, thereby increasing driving safety.

This document discusses, among other things, apparatus, systems, or methods to efficiently collect heart sound data, including detecting first heart sound information of a heart of a patient using a heart sound sensor in a first, low-power operational mode, and detecting second heart sound information of the heart using the heart sound sensor in a separate second, high-power operational mode. The operational mode of the heart sound sensor can be controlled using physiologic information from the patient, including heart sound information, information about a heart rate of the patient, or other physiologic information from the patient that indicates worsening heart failure.

A non-invasive method and system for assessing the survival of a transplanted flap involve the following steps. A control unit instructs a variable-frequency current generator circuit to generate a constant current at a fixed frequency and pass the constant current through a detection electrode. The detection electrode detects a bioelectrical impedance of the skin to which the flap has been transplanted, and the bioelectrical impedance of the skin is compared with a pre-defined threshold value. If the bioelectrical impedance of the skin exceeds the pre-defined threshold value, it is determined that an abnormal condition has occurred.

A method of assessing or monitoring the normal skin sympathetic nerve activity in a living subject, the subject having a skin, comprises assessing or measuring electrodermal activity, wherein the electrodermal activity is skin conductance, galvanic skin response, electrodermal response, psychogalvanic reflex, skin conductance response, sympathetic skin response or skin conductance level. Skin conductance may be assessed by calculating skin conductance fluctuation peaks per time unit, and when the skin conductance fluctuations peaks are above a certain predefined value, the normal skin sympathetic nerve activity is defined in an analyzing window with a length of about 15 to 60 seconds, the normal skin sympathetic nerve activity is assessed as being obtained or successful. Alternatively, the skin conductance may be assessed by calculating rise time of the mean skin conductance level, the area under the skin conductance fluctuations or the size of the amplitude of the skin conductance fluctuation.
