Automated System for Identification and Control of Pharmaceutical Codes
-
The automated system for identifying pharmaceutical codes includes two scanners of the pharmaceutical code, two sensors for the presence of an object and a data processing unit (BOD). When the box or instructions are passed under the object presence sensors, the farm code is read by the corresponding scanner and the results are transmitted to the computer via the Ethernet interface. The BOD verifies the correctness of the read out farm code by comparing this code with the reference farm code set at the beginning of the system operation. If the farm code has not been read or does not match the standard, the packaging machine stops and the type of error is displayed on the indicators.

Erbium Fiber Frequency Comb
-
Detailed description of item: The AOSense frequency comb is a low noise, polarization maintaining (PM) device. Key features include a PM fiber architecture centered at 1550nm with turnkey modelocking; a free-running linewidth of the carrier-envelope offset frequency of <200 kHz; a temperature-insensitive all-fiber f-2f interferometer exhibiting fceo beatnotes with SNR > 45dB (300kHz RBW); and dual fast/slow cavity length actuators with a bandwidth of >300 kHz. The repetition rate of the comb is factory set and allows matching across multiple combs for dual comb applications. The optics package incorporates an optical heterodyne module designed for locking to the comb to an ITU-specified laser reference. The comb is capable of supporting an Allan deviation of < 5 x 10-18 at 1 second and ~10-20 after 105 seconds. Add-on features include all fiber extensions to visible wavelengths corresponding to several atomic transitions. An integrated comb electronics package is currently under development.
