A hydrophilic coating is arranged on the permeable surface.
Claims12
A load handling apparatus comprising:
- an optical measurement device comprising:
- a permeable surface configured to communicate light to and from the optical measurement device;
- and
- a hydrophilic coating arranged on the permeable surface, wherein the coating is a nanotechnical product comprising nanostructured TiO2 in anatase form,
- wherein the optical measurement device is configured to transmit light through the permeable surface and receive reflections of the transmitted light through the permeable surface,
- a drive system;
- and
- a controller operatively connected to the drive system and the optical measurement device, and configured to:
- obtain measurement information from the optical measurement device;
- and
- drive the load handling apparatus on the basis of the measurement information.
A method for protecting an optical measurement device in a load handling apparatus comprising a permeable surface for communicating light to and from the optical measurement device, the method comprising:
- applying a hydrophilic coating to the permeable surface of the optical measurement device, wherein the coating is a nanotechnical product comprising nanostructured TiO2 in anatase form;
- transmitting light via the optical measurement device through the permeable surface;
- and
- receiving reflections of the transmitted light at the optical measurement device through the permeable surface,
- wherein the hydrophilic coating is arranged to decompose organic molecules using photocatalysis,
- wherein the nanostructured TiO2 includes nanotubes and nanoribbons,
- wherein the load handling apparatus further includes:
- a drive system;
- and
- a controller operatively connected to the drive system and the optical measurement device, and
- wherein the controller obtains measurement information from the optical measurement device and drives the load handling apparatus on the basis of the measurement information.
