Abstract: A power drive unit (PDU) includes a light source configured to generate light as pulses with pulse intervals between the pulses. The PDU also includes a light driver configured to control the light source to generate the light at a desired intensity. The PDU also includes a light receiver configured to receive a reflection of the light. The PDU also includes a processor coupled to the light receiver and configured to determine whether the cargo is positioned on the PDU based on the reflection of the light. The PDU also includes a light controller coupled to the processor and the light driver and configured to determine an adjustment to the desired intensity of the light generated by the light source based on an intensity of the reflection of the light and whether the light source is generating a pulse or a pulse interval.

Abstract: A lift roller may include a hub having a first surface, a second surface opposite the first surface, and a radially outward surface. The hub may define a channel extending through the hub from the first surface to the second surface. The lift roller may also include a rim portion rotatably disposed about the radially outward surface of the hub and a boss disposed on one of the first surface and the second surface.

Abstract: A unit load device (ULD) sensor for detecting presence and movement of cargo within an aircraft includes a light source designed to generate light as pulses with pulse intervals between the pulses and having a source lens designed to focus the light towards a first point that is a first distance away from the source lens. The ULD sensor also includes a light receiver having a light detector designed to receive a reflection of the light and a receiver lens designed to focus the reflection of the light towards a second point that is towards the light detector and a second distance away from the receiver lens. The second distance is different than the first distance and the detected reflection of the light is usable to determine the presence and the movement of the cargo.
