Interesting wheelchair insights, comparisons and tips on staying healthy and strong.

Tools should be considered for conversion to LRM drive. The ratchet mechanism could be replaced with a less expensive LRM drive. The tool based on LRM drive could easily rotate with all input motions.

The engine shown has a power stroke on both sides of the piston. There is no crank because the motion will be converted to rotation through an LRM. The benefits of the design are many and include:

  • Room for a power stroke on both sides of the piston, providing greater power density.
  • Ability to vary stroke and compression through the lever between pistons. This means multiple cycles and fuels could be used in the same engine.
  • No need for a geared transmission. Torque and speed ratios can be varied with lever changes prior to conversion to rotation.
  • The engine should be more efficient and pollute less.

This device is a portable power supply and auto jump start tool. It has the useful ability to be charged by muscle input. This is another example of an existing product that could be improved by incorporating the simplest form of the LRM into its manual power generation function. When a pull cord is used to turn muscle power into electricity, power is generated only on the pull but, not on the return of the cord. An LRM with an elongating input lever would more than double the efficiency of manual battery charging.

We are building the i5d wheelchair. The wheelchair requires an expert level of understanding of the LRM technology.  The wheelchair specifications include:

  • All control functions through the levers and are instantaneous.
  • Any lever motion is converted to rotation in the direction selected.
  • Steers using brakes and opposing wheel rotations.
  • Instant free-wheeling when no lever inputs are occurring.

The design specifications for the i5d wheelchair are difficult to achieve. The research and effort that was required to accomplish the specifications have made us very capable of helping you with any application questions you have.  We can help you fast track your project.
We will add LRM applications as they become available. We want to share our ideas and hope you share some of your own.The goal is to motivate you to build a team at your school, or with friends to develop an application using the patented LRM technology. We will be posting more details on how to get started. In addition we will explain how your LRM application can become a business of your own
