Image scanner

1. Introduction This is the first in a series of articles on using Forth to interact with the real world. We will explore how to control motors of various types (such as servomotors and stepper motors), switch power to devices, and sense the environment. Each article will present a project that can be used to demonstrate the ideas we are going to discuss. In this first article, I want to lay the foundation for the future columns and discuss the use of the PC parallel port to control stepper motors. We will adopt the fantasy that we are working on some microprocessor-based control application and will be using the PC parallel port as a proxy for the digital I/O channels on our controller. To the extent possible, the code will be written in high level (so that we can illustrate the principles clearly), and will be in ANS Forth. 2. The PC Parallel Port First, if you haven't already, go to your back issues of Forth Dimensions and find Ken Merk's article "Forth in Control," (FD XVII/2). In that article, Ken talks about using the PC parallel port for eight digital outputs. We will be expanding on that and use some of those other pins to get input as well as to provide output. A parallel port on the PC is really three address locations which, for conventional use, could be called #Data, #Command, and #Status. The port #Data is at the base address of the parallel port, #Status is at the base address plus one, and #Command is at base plus two. The base address…

The type of scanner is a modality-dependent feature. For example, MRIs and CT scanners are differ in size and functions. In medical ultrasounds, patients are not required to enter a scanner to be tested for CAD. These intrinsic modality-dependent differences were therefore considered as important test-specific attributes. In a DCE on scanning modalities to diagnose focal liver lesions, the type of scanner used was studied and shown to influence patient preferences for diagnostic tests (Whitty et…

Medical Center uses an electronic health record but that does not mean they don’t have to scan/assemble loose paper into EPIC. There are three steps to ensure the quality and efficiency of indexing and scanning forms and loose records into EPIC. The first step is to scan these loose forms. Most of the hospital scans their own records for the most part but for example HIM scans the ERs records and place them in EPIC. On February 9th, Devonn and I got a chance to scan records from OB and a few…

PhotoScan to correctly align them and show details. When zooming in on the cliff, the quality of the images is very good and one can point out geologic features such as rock layers, faulting (Fig. 3), erosional paths (Fig. 4), areas of possible landslides (Fig. 4) and sea caves (Figure 5). Field Mapping Four faults were mapped while walking alongside the cliffs after flying the drones. Dips were 42 to the S, 83 to the N, 70 to the S, and 44 to the south. If more faults were to be mapped, a…

For my creolization project I wanted to do images from back home so I decided to do a couple images that I had took when i was back at home in Hawaii. I will be going 3 images, for each image I will be talking about how I think it reflects an element or theme that Ivor Miller went over in his graffiti article and how it reflects to one of the Creative Spirit goals for class.What I got out of Miller’s article is that creolization is the concept of being able to bring two different aspects…

Today, I decided to play with my own camera of the ESO Canon. I thought that I have learned manual setting on my mentor’s Leica camera. So I wanted to try with my own camera, since it came with manual settings. First, I tried set different ISO, aperture, and shutter-speed numbers. I have to be honest that it wasn’t easy, because I couldn’t tell if is too dark or too bright. I just had to do my best to guess the ISO and shutter speed. With my first try, the first picture was too dark, so I turn…

photo shopped in some ways to fit the photographer. Haggart successfully expresses how photos aren’t original anymore. Haggart’s audience are readers who loves photography. Haggart successfully addresses their need for information by showing evidence of photos and the photographers that edit their photos like Ed Freeman. He says, “I am an artist. I’m interested in creating great pictures, not documentary images. I couldn’t care less if they’re real or not” (para.4). Freeman was addressing the…

in the desired result that someone wants to evoke by showing them a particular graphic image. Throughout her text, Sontag analyzes how a photograph could be a potential source that could help the world realize the atrocities of war, but Sontag also explores the possible effects that were not meant to be caused by the photograph itself through specific examples. In doing so, she demonstrates the validity of her observations, and also introduces us to the subject of propaganda. Propaganda has been…

Face it, Art is Art To be considered an artist is debatable. If one can be considered an artist, and if their work should even be considered as art, is argued constantly, but the truth is, no one can define an artist as one solid definition. The exact definition of art is considered: a wide variety of possessions and effects a person can show, create or capture. So, when it comes to photography, it shouldn 't be questionable if the photos themselves are art or not. They should be, because of…

A mirror shows nothing more and nothing less than the person or the scene reflected in it. A mirror cannot create nor destroy the images people see; mirrors are merely instruments for, what is most often, vanity. However in art, mirrors are used to exhibit much more than just a reflection: as is the case in both Un bar aux Folies Bergère by Éduoard Manet and Picture for Women by Jeff Wall . The mirrors used in both of these works of art mediate the scenes and the characters within them,…
