A capacitive sensor including an electrically conductive material, and a single electrode applied with positive potential, wherein the distance between the single electrode and the electrically conductive material determines the spherical radius for a proximity sensing range.

A multifunction wheelchair, with fixed or folding frame, is described. The multifunction wheelchair is reconfigurable, by a transformation mechanism, between a normal use, ergonomic configuration and a roll-over-toilet configuration. This transformation involves raising the seat of the wheelchair, as needed, to position the wheelchair over the determined height of a toilet, and opening a seat closure mechanism to expose a cutout in the seat for toilet use. This transformation may be at least partially automated. In examples, the multifunction wheelchair is equipped with electronics (e.g., camera, microcontroller) to determine the toilet seat height for making height and/or steering adjustments. The transformation mechanism may be provided as a retrofit kit.

Portable medical device

An eye-tracking system, including at least one vertical capacitance sensor, configured to measure the vertical position of a cornea of a user's eye by sensing a position of an eyelid of the user; and at least one horizontal capacitance sensor, configured to measure the horizontal position of the cornea of the user's eye by sensing a position of the user's eyeball.
