Abstract
A pressure sensitive mat is provided. The pressure sensitive mat includes a nanocomposite film, a first conductive foil, an oxide layer interposed between a first side of the nanocomposite film and the first conductive foil, a second conductive foil and a nanotube film interposed between a second side of the nanocomposite film, which is opposite the first side, and the second conductive foil.
Claims17
A personal transportation system, comprising:
- a body configured to transport an individual from a first location to a second location,
- the body comprising doors which are movable in a plane between open and closed positions;
- an entryway located at the first location and comprising a pressure sensitive mat configured to detect a presence of the individual out of the plane in which the doors are movable;
- and
- a control system configured to control movements of the doors between the open and closed positions based on a reading of the pressure sensitive mat,
- wherein the pressure sensitive mat comprises:
- a first film;
- one of a layer and a second film interposed between the first film and a first conductive foil;
- and
- the other of the layer and the second film interposed between the first film and a second conductive foil.
A hands-free call system of a personal transportation system, comprising:
- a body comprising an elevator car configured to transport an individual from a first location to a second location;
- an entryway located at the first location and comprising a pressure sensitive mat configured to detect a presence of the individual, which is readable as a call;
- a control system configured to control operations of the body responsive to the call based on a reading of the pressure sensitive mat;
- and
- at least one of a wall mounted call mechanism and an optical call mechanism,
- wherein:
- the pressure sensitive mat comprises ascend and descend sections,
- weight, time and noise characteristics of the reading of the pressure sensitive mat are analyzed and interpreted by the control system as the call, and
- the control system interprets pressure of a predefined magnitude and time on the ascend and descend sections as ascend and descend calls, respectively.
A hands-free call system of a personal transportation system, comprising:
- a body comprising an elevator car configured to transport an individual from a first location to a second location;
- an entryway located at the first location and comprising a pressure sensitive mat configured to detect a presence of the individual, which is readable as a call;
- a control system configured to control operations of the body responsive to the call based on a reading of the pressure sensitive mat;
- and
- at least one of a wall mounted call mechanism and an optical call mechanism,
- wherein weight, time and noise characteristics of the reading of the pressure sensitive mat are analyzed and interpreted by the control system as the call and the pressure sensitive mat comprises a visible progress indicator.
