Abstract: A cash processing device including: one or more medium holder units, each medium holder unit including a depository and a liquid spray mechanism configured to spray liquid onto mediums held in the depository; one or more spray controllers, each spray controller capable of reading unique identification information associated with the one or more medium holder units, and including a controller configured to control operation of a corresponding liquid spray mechanism based on a wireless signal from a first wireless communication section; and a system controller including a state controller that monitors occurrence of an abnormal state based on an input detection signal, and a second wireless communication section that uses the unique identification information acquired from each of the spray controllers to wirelessly communicate a control signal related to liquid spraying in response to a monitoring outcome.

Abstract: An optical transmission apparatus implemented as an OADM (Optical Add/Drop Multiplexer) includes quality monitors each for monitoring the quality of a signal arriving on a particular optical transmission path. A monitor/control unit converts quality signals output from the quality monitors to path-by-path bit error rates, or estimation values, and compares them to select a route. The monitor/control unit then generates a metric value “1” for the route selected and adds it to one of identical metric values, which are assigned to routes to the same destination, that corresponds to the route selected. The monitor/control unit can therefore select a route closer to actual transmission path conditions. A method of determining an optimal route for optical transfer is also disclosed.
