Described examples include a system for tracking a construction vehicle at a construction site. The system includes a Bluetooth receiver located at the construction site for receiving a unique identifier code transmitted by a Bluetooth beacon mounted on a construction vehicle, and the Bluetooth receiver is further configured to communicate the unique identifier code to a remote computer over a communications interface.

Autonomous tracking of construction vehicles using short range wireless beacons

Methods and apparatus for normalizing path length in an optical system for non-invasive glucose concentration. A method arrangement includes providing an optical energy source spaced from a first photo-detector by a sensing area; transmitting energy from the optical energy source onto the first photo-detector; storing a first reading corresponding to the light intensity observed by the first photo-detector; subsequently, introducing a container of solution including an optically active substance into the sampling area; transmitting energy from the optical energy source through the container in the sampling area and onto the first photo-detector; storing a second reading corresponding to the light intensity observed by the first photo-detector; determining a ratio of the first reading to the second reading; and determining a path length L by computing L=ln(ratio)/&#x3bc; where &#x3bc; is an absorption constant of the optical energy in the solution and container. Additional arrangements are disclosed.
