An information processing apparatus includes an acquisition unit that acquires a number of objects lining up in a queue when a target object targeted for measuring a queuing time enters the queue, a first detection unit that detects an object exiting the queue, and a measurement unit that measures, as a queuing time of the target object in the queue, a period from a time when the target object enters the queue to a time when a number of objects corresponding to the number acquired by the acquisition unit are detected by the first detection unit after the target object enters the queue.

An information processing apparatus that estimates waiting time in a waiting line with improved accuracy includes a first acquisition unit that acquires a number of objects in the waiting line, a second acquisition unit that acquires frequency of an object exiting the waiting line, and an estimation unit that estimates waiting time in the waiting line based on the acquired number of objects in the waiting line and the acquired frequency of an object exiting the waiting line.

A method for recording the number of sterilizations of a piece for a medical device. The piece can be a motor and/or a handpiece. The piece includes a temperature sensor and/or a pressure sensor and/or a humidity sensor and/or an angular position. The method includes the following steps: inserting the piece into the sterilization camber; detecting the sterilization based on the temperature and/or the pressure and/or the humidity and/or the angular position in which the handpiece is received in the sterilization chamber by the temperature sensor and/or the pressure sensor (102) and/or the humidity sensor and/or the angular position sensor. This solution allows recording of the number of sterilizations of a handpiece and/or a motor for a medical device, in particular for a dental device.
