• the data server 62 is an example of a data collection system configured to store data. The following may relate to all embodiments disclosed herein:
• the control unit 60 may be arranged to indicate a first tissue paper filling state indicating either an empty first seat 6 or an empty second seat 10, and a second tissue paper filling state indicating empty first and second seats 6, 10. Thus, in the first tissue paper filling state it is recommended to replenish the dispenser 2 with tissue paper. In the second tissue paper filling state it is required that the dispenser 2 is replenished with tissue paper.
• the control unit 60 may be arranged to indicate a third tissue paper filling state indicating at least partially filled first and second seats 6, 0. Thus, it is verified that no immediate replenishing of the dispenser 2 is required.
• the data server 62 may be arranged for communicating tissue paper filling states of the dispenser 2 to an operator. The tissue paper filling states may be presented on a display screen of the data server 62. In addition thereto, or alternatively, the data server 62 may present the tissue paper filling states of the dispenser 2 in a location remote from the data server 62, e.g. via messages from the data server 62 to a handheld device used by the operator.
• the data server 62 has been described to be a remotely located data server 62, which encompasses a data server 62 located outside a facility, such as a restroom, wherein the dispenser 2 is located, as well as a data server 62 located in a different building than wherein the dispenser 2 is located.
• the data server 62 may be locaily arranged, i.e. in the facility, such as a restroom, wherein the dispenser 2 is located.
• the data server 2 may thus form a locally arranged information system for providing an operator with paper tissue filling states of the dispenser 2.
• Example embodiments described above may be combined as understood by a person skilled in the art.
• the Fig. 4 embodiments may be provided with an optical sensor instead of the Hall Effect sensor.
• the light reflecting surface 58 may alternatively be positioned to reflect light onto the photosensitive element 56 when a seat is empty.
• the second arms 28, 28' may be shaped such that light from the light source 54 does not hit the second arms 28, 28' in one position thereof, i.e. in which one position light will not be reflected from the light reflecting surface 58 to the photosensitive element 56.
• Parts of the lever mechanism 20 may be provided on a rear side of the dispenser 2, e.g. the second arms 28, 28'. Accordingly, also the enclosure 52 and the sensor device 50 may be provided on the rear side of the dispenser 2. Therefore, it is to be understood that the foregoing is illustrative of various example embodiments and that the invention is defined only the appended claims.
