I need research to find out the origin and background of the 'American Rule' which is used in US courts dictating that suit parties pay their own attorney fees. Need when and under what grounds the rule was adopted. Need examples of Supreme court and 3rd circuit appeal cases rulings that decided it was the valid rule of the US courts . I do not need an actual essay, only a the above and a quick explanation. Thanks

Digital Circuit design and Computer Architecture

Design a RT MCU CANBUS gateway board. This board will be powered by 12 volts from a running vehicle. It needs to have the following: 3x Canbus 1x Lin 1x J1850 VPW Variety of 5V analog and digital inputs. Dedicated sensor ground and 5v channel. 12v outputs and grounded outputs.

I am after a simple circuit that when 5VDC is detected, it switches on. Then when 9VDC is detected switches the 5VDC off and leaves the 9VDC on. When the 9VDC is reduced the 5VDC comes on again. Obviously when there is no voltage all are off. I want to use it to switch a ground connection from another circuit board. At 0V a ground output from my circuit board to its pin1. At 5VDC the ground will go to pin 2 on my board. at 9V the ground goes to pin 3 on my board. So the designed circuit should have an input for the ground connection from my circuit board with 3 ground outputs. Hope that makes sense?

Hi, I currently have a circuit that has manual 'switches' in it. Currently there is a piece of plastic that spins around on a shaft, hit hits two manual contact switches depending on which way it is spinning. This is not a good design as each time it hits the switch it 'slows' it down from spinning. So we want to redesign this system as basic as possible using a 3D HALL SENSOR. So it detects the spinning, which way it is spinning, then triggers opto isolator output depending on which way it is spinning, clock wise or anti clock wise. New circuit board will - Detect spinning - Detect clock wise or anticlockwise - Send output depending on direction to an opt isolator. Board Design should include. 12v Input(marked +, -) 3 pin output (op...

I have an open source project coded in C that converts mouse input to analog stick output for game controllers. The program is fully functional except for an unforeseen issue that deals with the handling of the dead zone, currently the program doesn't seem to implement the dead zone correctly and I would like to have this fixed.

A business presentation is coming up about the voters circuit and we have images but it's needed to be re_made with word docs for it. So freelancers who can handle this are needed on this.
