Medicine packaging apparatuses and methods for accurately determining a remaining sheet amount of a medicine packaging sheet are described. The apparatus includes: a roll support section to which a core tube of a medicine packaging sheet roll is attached; a sensor disposed in the roll support section for outputting a count value according to a rotation amount; a wireless reader-writer unit for writing information to a core tube IC tag and reading said information; an information generation section for generating information to be written to the core tube IC tag; a remaining sheet amount estimation section for estimating a current amount of remaining sheet based on the information and dimensional information of the core tube; and a controller which selectively performs an operation if a reference time-point count value is not yet written to the core tube IC tag and another operation if the count value is already written thereto.

An apparatus is arranged for packaging sheet material, in particular banknotes, vouchers, checks, separation cards, etc., with a packaging device, packaging material dispensed from a roll for packaging the sheet material, and a control device controlling the apparatus. A monitoring device is provided for the packaging material, and the control device evaluates a signal of the monitoring device during the packaging of sheet material, in order to derive therefrom whether packaging material is present on the roll.

A method of tracking rotations of a drum includes activating a three axis accelerometer located on a side of the drum, measuring linear accelerations along three orthogonal axes using the accelerometer, determining whether a predetermined angle of the drum has been rotated based on the measured linear accelerations from the accelerometer, activating a gyroscope when it is determined that the predetermined angle of the drum has been rotated, measuring angular speed at the gyroscope, calculating a number of rotations of the drum from the measured angular speed, and deactivating the gyroscope when it is determined that the measured angular speed is lower than a noise floor level.

In one aspect, the present disclosure is directed to a sheet material dispenser. The dispenser can include support for supporting a supply of the sheet material, and a feed roller arranged along a feed path of the sheet material downstream from the supply of sheet material that is operable to pull the sheet material from the supply of sheet material for feeding thereof. Additionally, the dispenser can include a controller that is in communication with the feed roller and includes programming for monitoring rotation of the feed roller during a dispensing cycle for feeding a selected length of the sheet material from the supply of sheet material. A material supply monitoring system further can be in communication with the controller, and operative to detect a number of rotations or an angle of rotation of the supply sheet material during at least a series of dispensing cycles.

The present disclosure refers to a method and a system for tracking cable drums and length of cable on the drum. A method includes attaching a tracker device with a tracker identifier to a cable drum with a drum identifier, said drum identifier being associated in a database with drum dimensions and with cable dimensions of a cable stored on the drum. The method includes associating in the database the drum identifier also with the tracker identifier. The method includes when an event comprising at least a shock and/or a number of rotations of the cable drum around a longitudinal axis occurs, activating a first electronic circuit of the tracker device including a sensing device that detects at least the event, storing the detected event in a local memory of the tracker device and switching the first electronic circuit to standby mode after the detected event is stored.

An example media handling system includes a web media holder with a core hub capable of coupling to a core of a web media roll, a sensor to take a measurement at the circumferential surface of the web media roll, and a controller to determine a length of the web media roll. In that example, the controller may determine the length of the web media roll based on a first distance measurable by the sensor when the core hub is in a first orientation, a second distance measureable by the sensor when the core hub is in a second orientation after a number of rotations with respect to the first orientation of the core hub, and reference value corresponding to the core.
