A low cost fare collection system includes a removable farebox having an integral collection box. The farebox can be installed in a temporary installation at a fare collection location for the collection of fares and can be removed to a secure location for emptying and reconciliation. The farebox can include an integral collection box for receiving fares deposited in the farebox. The farebox can be configured such that the collected fares can be emptied only when the farebox is removed from the temporary installation to reduce tampering and theft. A fare validator can be used to verify the amount and value of a fare deposited in the farebox to eliminate human validation of fares. Electronic monitors can collect data relating to fares deposited, total revenue collected, time of fare collection, and other data items that can be retrieved when the farebox is removed and emptied.

An inline measuring device which serves for measuring at least one physical, measured variable of a medium conveyed in a pipeline, includes a measurement pickup of vibration-type, as well as a measuring device electronics electrically coupled with the measurement pickup. The measurement pickup includes at least one, essentially straight measuring tube serving to convey the medium to be measured and communicating with the connected pipeline, an exciter mechanism acting on the measuring tube for causing the at least one measuring tube to vibrate, during operation, at least at times and / or at least in part, with torsional oscillations about a torsional oscillation axis imaginarily connecting an inlet end of the measuring tube and an outlet end of the measuring tube, as well as a sensor arrangement for registering vibrations of the at least one measuring tube and delivering at least one oscillation measurement signal representing oscillations of the measuring tube. The measuring device electronics delivers, at least at times, an exciter signal driving the exciter mechanism and generates, by means of the at least one oscillation measurement signal and / or by means of the exciter signal, at least at times, at least one measured value, which represents at least one physical, measured variable of the medium to be measured. Moreover, the measuring device electronics determines, on the basis of the at least one oscillation measurement signal and / or on the basis of the exciter signal, repetitively, an oscillation frequency of the torsional oscillations of the measuring tube and the measuring device electronics monitors, based on the oscillation frequency of the torsional oscillations, at least one operating condition of the at least one measuring tube. Additionally provided is an inline measuring device of the described kind used for monitoring an operating condition of a tube wall, especially also a section of the attached pipeline.

The invention discloses an intelligent monitoring device of an animal ear tag. The intelligent monitoring device of the animal ear tag comprises an electronic monitoring device arranged at the front end of one of handles and a calipers folding induction device arranged on the handle and positioned near a rotating shaft. The invention further discloses an intelligent monitoring system of the animalear tag. The intelligent monitoring system of the animal ear tag comprises the intelligent monitoring device, as well as mobile communication equipment and a cloud server which communicate with eachother. The invention further discloses a monitoring method adopting the intelligent monitoring device of the animal ear tag. Judgment on whether to complete tag wearing is conducted through synchronization of an action signal catcher of the electronic monitoring device and the calipers folding induction device. The electronic monitor of the action signal catcher and the calipers folding inductiondevice are integrated on the calipers and are mutually connected, so that the functions of automatically determining that the ear tag is truly worn on earlaps of the animal and obtaining accurate tagwearing time are achieved, the false tag wearing phenomenon is avoided and the identity of the animal can be deeply traced.

The invention discloses a self-optimization control device and method based on crushing working conditions.
