A system for digitizing gauges, lights and other human-readable machine gauges and functions and status without interfering with the operation of the machine or requiring reworking or interfering with the existing machine wiring, signaling, electrical or mechanical elements or operating modes, or adding new digitizing equipment to the machine.

A visually sensible indicator of temperature including electronic temperature sensing circuitry sensing at least when a temperature exceeds at least one predetermined temperature threshold and providing at least one corresponding threshold exceedance output which is sensible as heat and a heat-responsive visually sensible display which is responsive to the at least one threshold exceedance output for providing at least one visually sensible indication indicating that the temperature has exceeded the predetermined temperature threshold.

A toothed belt includes at least one tension member and a plastics material matrix which at least partially encases the tension member. The at least one tension member extends in the plastics material matrix in a running direction and teeth of the toothed belt are formed transversely to the running direction in the plastics material matrix. The tension member is formed from an electrically conductive material and the plastics material matrix is formed from an electrically insulating material. The toothed belt has at least one electronic component which is embedded in the plastics material matrix and has at least one sensor which detects data on a condition parameter of the toothed belt. The at least one electronic component is coupled to the tension member via at least two voltage taps to tap a voltage induced in the tension member to supply the at least one electronic component with power.

Device and method for measuring and visualizing the sound level in a place where at least two people are gathered, comprising at least one sound detector which is connected to at least one visualization device in such a way that the visualization device responds to sound at the place. The visualization device is arranged so that it provides a gradually increasing response to gradually decreasing sound level. The visualization can be instantaneous or show average values for a defined period of time. The device is typically reversible so that it also provides a decreasing response to increasing noise levels. Instructions are given for use in gathering locations such as school classes, kindergarten rooms, meeting rooms, party rooms and group rooms for people with special behavioural challenges.

A display structure of a pressure gauge of an air compressor, the air compressor is received in an accommodation box, and a scale portion of the pressure gauge is viewable via a displaying opening of the accommodation box, the pressure gauge includes a cylindrical body which is transparent and is formed in a pen shape, and the pressure gauge includes a colored O-ring configured to indicate a pressure value of the scale portion. The scale portion is not printed on the cylindrical body of the pressure gauge and includes a transparent panel on which the pressure value of the scale portion is marked on an internal face of the transparent panel, and the internal face faces the cylindrical body of the pressure gauge.

A barcoded indicator operative to provide a machine-readable indication of exceedance of at least one threshold by at least one product quality affecting parameter, the barcoded indicator including at least a first barcode and at least a second barcode, the at least a second barcode being in a second barcode unreadable state prior to exceedance of the at least one threshold and upon exceedance of the at least one threshold the at least a first barcode becoming unreadable and generally simultaneously the at least a second barcode becoming readable.
