AMCSTI - ST2 Updated 7-20-10 The loads to the pivot base are going to be huge. Our original design was not beefy enough. Also the extra degree of freedom makes this thing way to squirly. Arms had to be extended way out to ends of racking. Mr. Hutchins conceived the "Tri-Cube" pivot base. Once installed, arms were brought back to home position under the panel - the device is operating per SM intent!

Roe v. Wade Oral Argument - Part 6 (1971) December 13, 1971 Watch the full program: An aspect of the decision that attracted comparatively little attention was the Court's disposition of the issues of standing and mootness. Under the traditional interpretation of these rules, Jane Roe's appeal was "moot" because she had already given birth to her child and thus would not be affected by the ruling; she also lacked "standing" to assert the rights of other pregnant women. As she did not present an "actual case or controversy" (a grievance and a demand for relief), any opinion issued by the Supreme Court would constitute an advisory opinion, a practice in which the Court traditionally did not engage. The Court concluded that the case came within an established exception to the rule; one that allowed consideration of an issue that was "capable of repetition, yet evading review." This phrase had been coined in 1911 by Justice Joseph McKenna. Blackmun's opinion quoted McKenna, and noted that pregnancy would normally conclude more quickly than an appellate process: "If that termination makes a case moot, pregnancy litigation seldom will survive much beyond the trial stage, and appellate review will be effectively denied." Associate Justices Byron R. White and William H. Rehnquist wrote emphatic dissenting opinions in this case. Justice White wrote: " I find nothing in the language or history of the Constitution to support the Court's judgment. The Court simply fashions and ...

AMCSTI - XY Stage featuring Source Two Advanced Stepper Motor Control March 17, 2010 - Please jump to 1:10 for a torque example.....Source Two's new advanced stepper motor controller running a pair of Detech size 11 linear stepper motors outfitted with encoders.. Stepper performance equivalent to a BLDC motor with some enhanced features. Excellent torque, shown at 1:10, even at higher speed, non-stall technology without resonance. Stage shown is used in conjunction with current system integration build, but can be customized per customer requirement.
Stepper Motor with Servo Motor Attributes - AMCSTI Our latest development exploits Stepper Motors with enhanced servo performance. Customer product solutions coming soon!
AMCSTI - NeverStall Stepper Motor Controller vs Standard Driver/Controller A brief demonstration of Source Twos Advanced Stepper Motor Controller technology (on the right). The motors are identical Detech NEMA 34 rotary steppers; standard controller technology is shown on the left. The purpose of the fixture is to see and feel the difference between the 2 technologies. Its a difference that you can hear and feel. Both stepper motors are receiving equal current and being run at approximately the same speed. The motor on the left is running like a stepper while the motor on the right behaves like a BLDC. The end result is higher speed with higher torque, quieter operation, very low resonance, no stalling and energy efficient operation. Modes include Velocity, Torque and Position and other based on customer requirements. More to come..
