A Symbol-based Bar Code Decoding Algorithm

We investigate the problem of decoding bar codes from a signal measured with a hand-held laser-based scanner. Rather than formulating the inverse problem as one of binary image reconstruction, we instead determine the unknown code from the signal. Our approach has the benefit of incorporating the symbology of the bar code, which reduces the degrees of freedom in the problem. We develop a sparse...

Implementation Planning for a Medication Bar Code System

The Canadian Pharmaceutical Bar Coding Project was a multi-year, multi-stakeholder national initiative designed to establish a pan-Canadian approach to automated identification of medications along the entire supply chain and medication-use system, from pharmaceutical manufacturers to the patient’s bedside. The project was co-led by the Institute for Safe Medication Practices Canada (ISMP Canad...

Error Estimates for a Bar Code Reconstruction Method

We analyze a variational method for reconstructing a bar code signal from a blurry and noisy measurement. The bar code is modeled as a binary function with a finite number of transitions and a parameter controlling minimal feature size. The measured signal is the convolution of this binary function with a Gaussian kernel. In this work, we assume that the blur kernel is known and establish condi...

A Metal-Acrylic Bar for Splinting Implant Impression Copings

Precise transfer of three-dimensional position of dental implants from oral cavity to the cast needs special considerations in impression making. It has been suggested to splint the copings by bars or acrylic resin material before making impression. Some problems regarding to polymerization shrinkage of acrylic resin have been reported. In this study, we describe a metalacrylic bar tha...
