Wheel hub type recognition device and wheel hub identifier tracing management system

The present invention provides a wheel hub type recognition device and a wheel hub identifier tracing management system comprising the wheel hub type recognition device. The system comprises a field information interconnection device; a wheel hub type recognition device; an identifier generating device used for generating an identifier on a wheel hub; a wheel hub clamping and positioning device; and a central control device. The wheel hub type recognition device recognizes the type of a target wheel hub according to hub recognition features and generates the complete hub information in combination with the preset relevant production information. The central control device generates a unique recognition number corresponding to the target wheel hub according to the acquired complete hub information. The identifier generating device receives the above wheel hub information and the recognition number, and generates an identifier on the wheel hub and the attached label carrier thereof. The field information interconnection device participates the presetting or downloading process of the production information and uploads the recognition number of the target wheel hub and the complete hub information corresponding to the target wheel hub after the generation of the identifier. In this way, during the subsequent process of the wheel hub production and the overall usage life cycle thereof, the recognition number can be utilized at any time. Through simply searching an interconnection database, the comprehensive traceability management of each wheel hub is realized.

Devices, systems and method for calibration of systems

An injector system for use in injecting a fluid into a patient includes a communication system adapted to receive data from at least a first sensor that measures a value first variable. The communication system is also adapted to receive data from a calibrated sensor that measures a value the first variable. The injector system further includes a calibration system adapted to calibrate output from the first sensor in response to output from the calibrated sensor. An injector for use in injecting a fluid into a patient, includes a first sensor that measures a value first variable, a communication port adapted to receive data from a calibrated sensor that measures the value the first variable, and a controller adapted to compare data from the calibrated sensor with data from the first sensor and to calibrate output from the first sensor. The devices, systems and methods of the present invention are applicable to systems other than injection systems. For example, a method for calibrating a system (for example, an injector system) includes: placing a calibrated sensor in communication with the system; making a measurement of the value of at least a first variable with the calibrated sensor; transmitting the measured value from the calibrated sensor to the system via a data communication system in operative connection between the calibrated sensor and the system; making a measurement of the value of the first variable with a sensor of the system at approximately the same time as the measurement made with the calibrated sensor; comparing the value of the first variable measured with the calibrated sensor with the value of the first variable measured with the system sensor; and calibrating the output of the system sensor at least in part based upon the comparison.
