Abstract: A device includes at least one array of photoconductors, at least one bias voltage source, and at least one photoconductor readout circuit. Each photoconductor is configured for exhibiting an electrical resistance dependent on an illumination of its light-sensitive region, and at least one photoconductor of the array is designed as characterizing photoconductor. The bias voltage source is configured for applying at least one alternating bias voltage to the characterizing photoconductor or at least one direct current (DC) bias voltage to the characterizing photoconductor. The photoconductor readout circuit is configured for determining of a response voltage of the characterizing photoconductor generated in response to the bias voltage. The response voltage is proportional to a variable characterizing the array of photoconductors. The photoconductor readout circuit configured for determining of the response voltage of the characterizing photoconductor during operation of the array of photoconductors.

Abstract: One or more video gateway devices configured to: access pre-configured criteria including at least a first condition, a second condition, and a first event; access video content captured by cameras configured to capture video of areas of a manufacturing facility; determine, based on an analysis of the video content, that the first condition is satisfied; access sensor data from one or more sensors; determine, based on an analysis of the sensor data, that the second condition is satisfied; and based on determining that the first and second conditions are satisfied, cause the first event to be executed.

Abstract: A hand held spray dispenser in which air and liquid are pressurised towards a mixing chamber by energy generated by a manual activation element that is rotated with a unidirectional twist to energise one or more energy storage bodies, energy from which is released to generate sufficient air pressure and air flow and sufficient liquid flow for a spray to be formed from the air-liquid mixture.

Abstract: A management server receives a request to view video content; access a stream of video content corresponding to the request; access and store, in one or more databases, metadata associated with the video content, wherein the metadata includes a plurality of detections and was generated by the video gateway device based on an analysis of the video content and previously uploaded to a remote computing device; generating and causing display of a user interface that includes: the stream of the video content, a seek bar configured to be manipulated by a user so that the user can navigate through the video content, and the metadata overlaid on the seek bar such that the plurality of detections are overlaid at locations on the seek bar corresponding to when the plurality of detections were detected.

Abstract: The invention relates to a roll stand (2) for rolling, in particular cold-rolling, metal products, comprising at least one actuator (16) which can be actuated for actively damping vibrations in the roll stand (2), and at least one supporting roll (10) which is non-adjustable or can be adjusted exclusively via a readjusting device for pass line adjustment (13) of the roll stand (2) for supporting a working roll (5) and/or intermediate roll of the roll stand (2), wherein the supporting roll (10) is guided at the ends via a respective bearing unit (11) on a rack (8) of the roll stand (2). In order to enable an optimal active damping of vibrations in a roll stand (2) of this type with low engineering effort, the invention proposes that the supporting roll (10) is supported on the actuator (16) via at least one bearing unit (11) and that the actuator (16) is supported on a section (17) of the rack (8) either directly or indirectly via at least one component (14) of the readjustment device (13).
