In the field of the counting of objects, a use is provided of a photosensitive assembly comprising at least one photodiode or one photoresistor, and a source of uniform illumination for illuminating the assembly, the establishment of a reference current supplied by the photosensitive assembly for an illuminated region of this assembly corresponding to a given fraction of the surface of the assembly, the disposition of objects to be counted against the photosensitive assembly, the illumination of the assembly by the source, the objects masking a part of the surface of the assembly, measurement of the current supplied by the assembly, and determination of a ratio between measured current and reference current to deduce the proportion between the surface area of photosensitive element illuminated and the surface area masked by the objects disposed. From this ratio, information on the number of objects disposed on the photosensitive assembly is extracted.

A capacity counter system has a central capacity controller, a clicker to indicate when people enter or leave an area, and a video system for displaying a running count of how many people are in the area. The controller, clicker and video system communicate wirelessly using protocols that allow the controller to communicate with a plurality of clickers while being in close proximity to other controllers serving adjacent areas.

An arrangement of counting passengers in an elevator using two separate counting mechanisms is disclosed. The elevator car typically has a curtain of light arranged to the door and a load weighing device arranged to measure the weight of the elevator car. From the information recorded by the curtain of light and the load weighing device, it is possible to count the number of passengers. The reliability of the counting results can be improved by processing the counting results for forming a combined counting result that provides a more reliable counting result when the independent counts deviate from each other.

The present invention relates to a chip counter, which transmits an X-ray beam through a tape reel around which a tape having a plurality of semiconductor chips mounted in a row therein is wound, acquires an image scattered or diffracted by the semiconductor chips, and processes the acquired image, so as to count the number of the semiconductor chips, wherein: the X-ray beam transmitted through the tape reel (1) is sensed by a fluorescent intensifying screen (60); a fluorescent light emitted from the fluorescent intensifying screen (60) according to the sensing of the X-ray beam is captured by a camera (70), so that the number of the semiconductor chips is counted from an image in which the semiconductor chips are displayed by a dotted image; and the camera (70) is protected by an X-ray beam shielding member (100: 110; 120; and 130).

A mechanical energy-based self-powering counting system is provided. The system includes an electromagnetic power generator, a count measuring circuit, a count energy supply circuit, a controller and a wireless transmission module. The electromagnetic power generator is driven by an external device and produces an electric signal and outputs the electric signal to the controller after passing it through the count measuring circuit. The controller processes the received signal, updates a count according to certain programming rules and sends data to the wireless transmission module. The energy from the electromagnetic power generator flowing through the count measuring circuit can supply power to the controller. An energy storage module in the count energy supply circuit performs voltage feedback on the controller. The controller monitors the voltage of the energy storage module to control whether it enters a charging state.

Techniques are disclosed for a hybrid undo/redo for text editing, where non-linear undo and redo operations are performed across dynamic regions in a document and linear undo and redo operations are performed within the dynamic regions in the document. In an example, the hybrid undo/redo may be achieved by maintaining respective region offset values for the dynamic regions created in a document by the edits made to the document. In operation, the respective region offset values associated with the dynamic regions can be used to negate or otherwise counteract the effect of edits made in the dynamic regions.
