Abstract: 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 C14 source, a scintillator adjacent the C14 source, 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.

Abstract: 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.

Abstract: 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.

Abstract: A feeder roller apparatus for high speed image scanning equipment, which improves feeding of documents, and in particular short documents, sequentially fed from a stack. The feeder apparatus comprises a PIC roller and an infeed roller which are selectively, independently driven via a dual drive shaft, composed of an inner drive shaft and an outer drive shaft, driven together or selectively, independently by a main motor. An electro-mechanical clutch, when energized is used to drive the PIC roller. A sensor is provided downstream of the rollers to recognize when a document is being fed. Initially, the clutch is energized, and both rollers are driven. When the first sheet reaches the sensor, the clutch is de-energized, cutting off the drive to the PIC roller. The main motor continues driving only the infeed roller until the first sheet is fed.

Abstract: A system for applying linerless labels to mailing items includes a label feeder for feeding a continuous length web of linerless label material from a supply roll through a loop path to a label applying station juxtaposed to the path traversed by mailing items conveyed on edge in sequential fashion by a belt conveyor. The label material passes through a web guide and advance assembly to a cutter station operative to sever the label material transversely and create labels of desired height. A paddle member is operative to engage and hold each successive label as it is being severed from the label material web generally simultaneously to adhere the adhesive side of the label against a mailing items passing through the label applying station. The various operating functions of the linerless label applying system may be coordinated by conventional control logic.
