Carrier for use in a diagnostic analyzer

Example apparatus and methods for use in normalization of testing machines used to test samples in vessels are disclosed. An example apparatus includes verification source and a photon emitter positioned in the verification source. The example photon emitter includes a Csource, a scintillator adjacent to the Csource, and a filter adjacent to the scintillator. The example photon emitter is to emit photons through the filter for detection by a photon counter.

Device for use in normalizing readings on a testing machine

An example optic module verification device for use in periodic normalization of a testing machine used to test samples in wells is disclosed. The example testing machine includes a plurality of photon counters that each count photons emitted from different wells. The example verification device includes a plurality of verification wells located so as to each be associated with one of the photon counters when used in the testing machine. The example device also includes a photon emitter in each verification well, each photon emitter including a Csource, a scintillator adjacent the Csource, and a filter over the scintillator. The example photon emitters each have a determined initial base value for emitted photons, and each photon emitter is positioned in its verification well to emit photons through the filter to the associated photon counter when used in the testing machine.

An optic module verification device for normalizing between X photon counters, including a verification tray with X verification wells and a modular photon emitter in each verification well. Each photon emitter includes a spring, a Beta source disk, a scintillator disk adjacent the Beta source disk, and a neutral density filter over the scintillator disk, all of which are encapsulated in a cylindrical chamber with the filter adjacent an opening on one end of the chamber and the spring biasing the Beta source disk and the scintillator disk toward the opening. The device is periodically used for normalization, and may be updated when emitted photons fall below a desired level by replacing the scintillator disk and then determining a new normalized reference values for each photon emitter.

A printer for printing indicia upon media with print head and platen assemblies with ease of exchange and re-alignment features. The print head may be coupled to a print head bracket, the print head bracket removably coupled to the top cover of the printer by, for example, guide tabs of a print head support structure which mate with guide slots of the print head bracket. The print head bracket having alignment forks for aligning the print head with the platen. The printer also includes a platen bracket for maintaining the platen in the printer. The platen bracket being easy to remove to replace the platen.
