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.

The invention relates to a method for automatically displaying measurement values, having the method steps of transmitting a number of measurement value groups detected by a sensor system, wherein each measurement value group has n variables; ascertaining an optical value range for the display of the n-th variables; transforming the values of the n-th variables of the measurement value groups into optical values from the optical value range; displaying variables 1 to n−1 of the measurement value groups in a coordinate system with n−1 dimensions; and displaying the points of the measurement value groups in the optical values assigned to the n-th variables of the measurement value groups.

A data logger device is provided. The data logger device according to an example embodiment of the present invention comprises: a sensing unit mounted on one surface of a flexible printed circuit board, and including a sensor that detects at least one piece of information; a display unit that, when an abnormal state is detected on the basis of information measured via the sensing unit, irreversibly displays the abnormal state; a control unit that controls driving of the sensing unit and the display unit; a power supply unit that provides driving power to the control unit; and a cover member that prevents the outside exposure of the sensing unit, the display unit, the control unit, and the power supply unit.

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 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.

A footwear indicator is discloses capable of providing an indication of the degree of wear on a footwear, for example, an athletic or other type of shoe.

A quality management system for products including a multiplicity of barcoded quality indicators, a barcode indicator reader and a product type responsive indication interpreter, each of the barcoded quality indicators including a first barcode including at least one first colorable area, the first barcode being machine-readable before exceedance of the at least one time and temperature threshold, at least a second barcode including at least one second colorable area, the second barcode not being machine-readable before exceedance of the at least one time and temperature threshold, a coloring agent located at a first location on the indicator and a coloring agent pathway operative to allow the coloring agent to move, from the first location to the first and second colorable areas simultaneously thereby causing the first barcode to become unreadable and at the same time causing the second barcode to become machine-readable.

A non-invasive dental or surgical monitoring system is disclosed. The monitoring system is comprised generally of dental or surgical equipment to be monitored, a main sensor unit, a set of sensors. The main sensor unit is in communication with various sensors removably attached to the equipment. The sensors monitor environment conditions related to the equipment rather than directly monitoring the equipment. The collected data is sent to the main sensor unit and can be accessed, or wirelessly transmitted by signal to a device or devices at another location. As collected data aggregates, a data profile can be created, machine learning can be used to discover patterns, and predictive analysis can be incorporated to help software make predictions of, or spot in real time, equipment problems based on deviations from the profile.

Poster quality of codified standards for medical, food or industrial product which consist of chemical material that Influenced by surrounding factors such as temperature, humidity and expiration, where the ratio of the chemical material of the poster is adjusted depending on the product type and the extent of its vulnerability to these factors. The change of poster color indicates of exceed standards.

Provided are a color control method and apparatus of a to-be-displayed object, a measurement device, and a medium. The method includes: acquiring to-be-displayed object information of the to-be-displayed object, and generating a corresponding to-be-displayed object interface according to the to-be-displayed object information; configuring color information of the to-be-displayed object interface based on a preset to-be-displayed object color mapping frame, where the to-be-displayed object color mapping frame is used for configuring a mapping relationship between the color information and the to-be-displayed object information of the to-be-displayed object on a current display interface; and displaying the to-be-displayed object information of the to-be-displayed object interface according to the configured color information.
