Discussed is a cell tracking device that can include a transfer section configured to transfer a plurality of battery cells; and a reading section arranged on the transfer section and configured to read a marking part including information unique to each of the plurality of battery cells, wherein the reading section comprises a light source that radiates light on the marking part; a first mirror located adjacent to the marking part and illuminating a first image of the marking part; and a second mirror located at a central part of the reading section and illuminating the first image of the marking part illuminated on the first mirror.

An imaging system includes a camera having a field of view, a set of axially spaced moveable mirrors supported on a rotor to rotate the mirrors within the field of view of the camera, and a set of stationary mirrors supported to redirect the fields of view from the set of moveable mirrors to provide multiple fields of view at different angles.

A scanning code symbol reading system includes an analog scan data signal processor for producing digitized data signals, wherein during each laser beam scanning cycle, a light collection and photo-detection module generates an analog scan data signal corresponding to a laser scanned code symbol, an analog scan data signal processor/digitizer processes the analog scan data signal to generate digital data signals corresponding thereto, and a synchronized digital gain control module automatically processes the digitized data signals in response to start of scan (SOS) signals generated by a SOS detector. The synchronized digital gain control module generates digital control data which is transmitted to the analog scan data signal processor for use in controlling the gain of a signal processing stage in the light collection and photo-detection module and/or analog scan data signal processor, during the corresponding laser beam scanning cycle.

An optical scanning apparatus includes an optical box having a top surface that is constituted by a single lid. A first surface of the top surface is disposed closer to a rotary polygon mirror than a second surface and is disposed closer to a bottom surface of the optical box than an edge portion of a light deflector positioned farthest from the bottom surface. A third surface of a convex portion of the top surface is positioned farther from the bottom surface than the first surface. A lower edge portion of the convex portion is disposed outside a circumscribed circle of the rotary polygon mirror.

A container arranged for containing a precursor material for use with a machine for preparing a beverage and/or foodstuff, the container including a machine-readable code storing preparation information for use with a preparation process performed by said machine, the code comprising a plurality of elements, wherein the elements of the code are arranged circumferentially to be read sequentially when the container is rotated about an axis of rotation relative a code reader, wherein the code is arranged as a plurality of directly adjoining discrete positions and an absence or presence of a primary element at a discrete position encodes the preparation information, wherein boundary elements are arranged at a boundary between two or more adjoining primary elements, and/or at a boundary between two or more adjoining absences of primary elements, and the boundary elements are of different reflective properties to a primary element or an absence of a primary element.
