SD Capture version 4.4 is released. new features include mirror image added to editing capabilities.

February 23, 2000

E.F.U.S. v2.5

E.F.U.S. version 2.5 is released. New features include the ability to save all calculations to disk as text files.  New saves can be appended to existing save files providing a method by which to view calculation histories.

February 8, 2000

Registration numbers for e-mail purchases are now generated in real time and sent upon completion of the credit card transaction.

December 31, 1999

SD Capture v4.3

Improved palette management for 8 bit operating environments. File saves for eight bit .gif's are much faster,  DIB bits are read directly from an allocated memory block into an array then fed to the compressor.

December 1, 1999

SD Capture v4.2

Improved memory usage and GDI object management.  Paint message handlers for edit procedures have been completely rewritten providing improved performance when multiple edit windows are active.  Assorted code optimizations and streamlining throughout the program.  

November 20, 1999

SD Capture v4.1

Color palette changes are now implemented in real time allowing the user to preview the changes before saving.  Palette depth can now be scaled up or down from 4 to 24 bit prior to saving.

November 12, 1999

SD Capture 4.0 receives

November 2, 1999

SD Capture v4.0

Interface changes, code optimizations, multithreading for processor intensive color processing tasks and an increased array of file save formats.

October 31, 1999

SD Capture is awarded a five star rating by  Super Shareware.

October 27 1999,

Credit card orders are now supported.

October 24, 1999

SD Capture 3.5 is released.  An expanded set of image printing options is now supported including "stretch to page" and "best fit" stretch.

October 23, 1999

Web page redesigned, new content added, site map updated.

E.F.U.S. Version 2.0

In addition to an already rich feature set, E.F.U.S. now includes a voltage drop calculator for DC and AC power.  Calculations are made based on a variety of user defined data and conditions including, temperature, supply voltage, wire size and type, conduit type circuit load and one way circuit length. 

The following formulas are used to calculate circuit voltage drop.

AC Voltage Drop

Zc=(R x cos(phase angle))+XL x sin(phase angle)

Single Phase

VD=Zc x (length/1000) x amps

Three Phase Line To Line

VD=line to neutral voltage drop x square root of 3

DC Voltage Drop

VD=(2 x Length x Resistance x Amps)/1000

Where

VD=voltage drop  Zc=corrected impedance  R=conductor resistance  Phase Angle=power factor phase angle (in degrees)  XL= reactance  Amps=circuit load in amps  Resistance= conductor resistance Length=one way length of circuit
