A system for handling a lost item in an autonomous vehicle and a server. The vehicle includes a vision sensor configured to respectively capture a first vehicle interior image and a second vehicle interior image when a passenger boards and alights from the vehicle. The vehicle is configured to transmit the captured first vehicle interior image and second vehicle interior image to the server. The server is configured to compare the first vehicle interior image with the second vehicle interior image and transmit lost item information to the passenger when the lost item in the vehicle is sensed.

A weight measuring hitch ball assembly is described. The assembly can include a hitch ball having a ball and a lower portion. The assembly can also include a body portion defining a hitch ball opening that slidably receives the lower portion of the hitch ball. The assembly can further include a load measurement device operably associated with the body portion and the hitch ball to determine a magnitude of a force acting on the hitch ball. Additionally, the assembly can include a hitch mount interface configured to interface with an attachment structure that facilitates coupling the weight measuring hitch ball assembly to a tow vehicle.

An elevator car load measurement system for determining a load of an elevator car includes a plurality of at least two force sensors that are daisy-chained and connected to a controller for determining the load. Each force sensor measures a force exerted by the elevator car on the respective force sensor and generates a frequency signal with a square-wave form, wherein the frequency signal is proportional to the respective measured force. At least one of the force sensors adds a first frequency signal received from the previous force sensor along the daisy chain a second frequency signal generated by the at least one force sensor to generate a frequency sum signal, the last of the force sensors in the daisy chain forwards the frequency sum signal to the controller.
