BAR CODE BASICS Labeling our world requires, well, labels. Today, this typically amounts to what’s commonly called a bar code. This term is synonymous with the Universal Product Code (UPC) and European Article Number (EAN) codes found on nearly every manufactured good and familiar to most consumers through their nearly ubiquitous use at grocery store checkouts. Depending on the exact type (www....

This paper presents a Cuckoo Optimization Algorithm (COA) model for the cost optimization of the one-way and two-way reinforced concrete (RC) slabs according to ACI code. The objective function is the total cost of the slabs including the cost of the concrete and that of the reinforcing steel. In this paper, One-way and two-way slabs with various end conditions are formulated as ACI code. The t...

We investigate the problem of decoding bar codes from a signal measured with a hand-held laser-based scanner. We develop a sparse representation of the UPC bar code and relate it to the measured signal. A greedy symbol-based algorithm for decoding a bar code is proposed. We show that the algorithm is robust to noise, and to unknown parameters in the scanning device. Numerical examples further i...

Dotted Data Matrix two-dimensional bar code is widely used in the field of machinery and electronics, automobile manufacturing, pharmaceutical and medical, military firearm management etc. Compared with the standard Data Matrix two-dimensional bar code, Dotted Data Matrix bar code is composed of solid dots, which has no obvious characteristics of “L” shaped seek border region. The gaps between ...

Position The American Society of HealthSystem Pharmacists encourages hospital and health-system pharmacies to incorporate bar-code scanning into inventory management, dose preparation and packaging, and dispensing of medications. The purpose of such scanning is to ensure that drug products distributed, deployed to intermediate storage areas, or used in the preparation of patient doses are the c...

In this paper, through the research on two-dimensional bar codes of food source tracking; a set of traceability tracking system was designed based on the two bar coding algorithm and decoding algorithms. This system could generate PDF417 code based on food production, logistics and transport, supermarket and other storage information. Consumers could identify PDF417 code through a client based ...

Safe handling and preparation of breastmilk within the hospital setting are often taken for granted, and the process may not be scrutinized until problems arise. Areas of concern focus on both risk of contamination of breastmilk feedings due to handling and fortification and risk of a breastmilk misadministration. In two phases, Children's Hospital of Orange County (Orange, CA) implemented cent...

Accurate edge localization is essential in bar code decoding. Since speckle noise is the most dominant form of noise in laser bar code scanners, it is important to fully understand its effects on edge detection. Starting with the basic statistical properties of speckle patterns, we present stochastic analysis of speckle noise. We derive the autocorrelation function and power spectral density PS...

This review paper reports the applications of magnetic microbeads in biosensors and bio-bar code assays. Affinity biosensors are presented through different types of transducing systems: electrochemical, piezo electric or magnetic ones, applied to immunodetection and genodetection. Enzymatic biosensors are based on biofunctionalization through magnetic microbeads of a transducer, more often amp...
