A photon-counting time-of-flight ranging technique developed for the avoidance of range ambiguity at gigahertz clock rates.

This paper describes a rapid data acquisition photon-counting time-of-flight ranging technique that is designed for the avoidance of range ambiguity, an issue commonly found in high repetition frequency time-off-light systems. The technique transmits a non-periodic pulse train based on the random bin filling of a high frequency time clock. A received pattern is formed from the arrival times of the returning single photons and the correlation between the transmitted and received patterns was used to identify the unique target time-of-flight.

A cooperative approach to standardizing care for patients with AMI or heart failure.

Background: In fall 2003 the five hospitals in Wichita, Kansas, formed a collaborative to improve care for patients presenting with acute myocardial infarction or heart failure (HF). Standard order sets were developed from guidelines developed by the American College of Cardiology and the American Heart Association. THE WICHITA CITYWIDE HEART CARE COLLABORATIVE GETS TO WORK: The order sets, which highlighted the appropriate interventions and made their implementation a "checkbox" activity, were placed in the progress note section of the medical record.
