Digital and Analog Measurements in a Network
The Hands-on XBEE Lab Manual, 2012Co-Authors: Jonathan A. TitusAbstract:An XBee module configured in a network as an End device can send its Coordinator information about analog and digital signals connected to it. But most people prefer information as voltages, temperatures, pressures, or in other physical units rather than binary or hexadecimal data. This experiment shows how End-device modules will respond to an API Command packet that requests information for all active digital or analog inputs. Software that runs on an ARM mbed or on an Arduino Uno module will send a Force Sample Command packet, obtain data, check for errors, and print information as a voltage or as a short sentence for digital signals.

Differential gloss quality scale experiment update: an appearance-based image quality standard initiative (INCITS W1.1)
Image Quality and System Performance IV, 2007Co-Authors: C.c. Kuo, Eric Maggard, Dale R. Mashtare, Peter C. Morris, Susan FarnandAbstract:Surface characteristics of a printed Sample Command a parallel group of visual attributes determining perceived image quality beyond color, and they manifest themselves through various perceived gloss features such as differential gloss, gloss granularity, gloss mottle, etc. Extending from the scope of ISO19799 with limited range of gloss level and printing technologies, the objective of this study is to derive an appearance-based differential gloss quality scale ranging from very low gloss level to very high gloss level composed by various printing technology/substrate combinations. Three psychophysical experiment procedures were proposed including the quality ruler method, pair comparison, and interval scaling with two anchor stimuli, where the pair comparison process was subsequently dropped because of the concern of experiment complexity and data consistency after preliminary trial study. In this paper, we will compare the obtained average quality scale after mapping to the sharpness quality ruler with the average perceived differential gloss via the interval scale. Our numerical analysis indicates a general inverse relationship between the perceived image quality and the gloss variation on an image.
