Abstract: In an example, physiological signal(s) are received from physiological sensor(s) configured to measure at least one physiological property of a user. An arousal of at least one characteristic of at least one treatment resistant mood disorder is detected through employment of an estimation method based at least in part on at least one of the physiological signal(s). A value for at least one of a plurality of stimulation parameters is selected based at least in part on at least one of the physiological signal(s). An electric field based at least in part on the arousal is produced. The electric field is configured to stimulate at least a portion of a median nerve of the user transcutaneously. The electric field is based at least in part on at least some of the plurality of stimulation parameters.

Abstract: The breach lock is for use in securing open the breach of an assault rifle during cleaning of the bolt action and the breach between uses of the assault rifle. The breach lock includes a notch along a top of the breach lock and a hole along the breach lock, which define a length. The breach lock is inserted between the upper receiver assembly and the lower receiver assembly so as to prevent any rotation there between. The notch bolts to the upper receiver assembly whereas the hole employs the pin of the assault rifle to engage the lower receiver assembly. The breach lock is simple in installation and removal with use of an assault rifle, and prevents unwanted collapse between the upper and lower receiver assemblies, which would otherwise pinch or injure the hand and fingers of an end user when cleaning.
