Abstract: Medical devices and methods of medical treatment for the electrical and sensory stimulation of target nerves to enhance waste clearance in the brain for treating neurological disorders such as Alzheimer's disease (AD), including prodromal, mild cognitive impairment (MCI) and early stage Alzheimer's disease.

Abstract: A differential gear mechanism, of either the locking or limited slip type, including a gear case (11) rotatably disposed within an outer housing (H) and a mechanism (37) to limit rotation of side gears (23,25) relative to the gear case, this rotation limiting mechanism including a member (41) which is axially moveable between a first position (FIG. 2) and a second position (FIG. 5). The mechanism includes a sensor assembly (95;101) and a sensor element (97;107) disposed adjacent the gear case (11). The axially moveable member includes a sensed portion (89) surrounding an annular surface (11S) of the gear case, and disposed between the annular surface and the sensor element, in one embodiment. Movement of the sensed portion corresponding to changes within the mechanism between unlocked and locked conditions results in the sensor assembly transmitting an electrical output.
