Thumb screws, wing nuts or knobs are usually hand tightened to secure parts that do not require large clamping forces. However, they are subject to undesirable loosening due to vibration.

There is a need for a more reliable hand tightened fastener that does not loosen.

The applied asymmetric thread design features a continuously inclined surface (a) (Fig.1) and a cylindrical profile that works with standard threads, providing secure, self-locking, vibration resistant connections, while eliminating the potential for fatigue failure.

A significant feature of this thread is its shallow incline. This incline (a) forms a wedge-like feature to hold parts in place when an axial force (clamping) is applied.

The asymmetric thread allows the mating fastener with standard ...


Introduction

The vibratory cavitation piston pumps (VCPP) are intended for moving and spraying solutions and aggressive liquids.

It is remarkably that the VCPP technology was opened, studied and patented in the USSR more than 30 years ago by Grigori Lishanski, PhD. A number of vibrating pumps were registered as “vibrating pumps of Lishanski."

Further, based on results of our long-term research in the USA, the second generation of VCPP have been created with technical possibilities (productivity, pressure, reliability and profitability ) considerably extended. For example, the specified technology has allowed us to create pumps which swing and spray liquids in broad range of viscosity: water and ...

Project Overview:
This project will create an energy producing device that will take in an underwater current, increase its velocity 3 to 10 times. This gives the CKM an advantage over most designs today for current to power devices. The (CKM) will be scalable in both size and water inlet to output size making it flexible and adaptable to the situation at hand.

The project will produce a device that uses a circular shape similar to a sea shell with a turbine in the center. The theory is the opening (facing the oncoming current) will be proportioned to the internal outlet. As the water is circulated, the runway narrows to from input to outlet with the turbine situated at ...

A Pair Push & Pull Thermal Dynamic Engines.
A super flat profile Linn's thermal engine panel, 1 sq-meter X 3" thick, consists of 2 sets ultra low temperature thermal dynamic engines configured as push and pull cranking mechanism to drive a micro electric generator on top. Its peak power output capacity is near 500 Watts per square meter, near 3X of same square meter size most efficient solar photovoltaic panels.

Reinvention of the Stirling engine
Linn's thermal dynamic engine panel is based on Stirling engine working principle. How Stirling engine toys work ? Please search YouTube.com. Linn reinvented to sink the small power piston inside the displacer, so that to make the engine super low profile, merely 3" . ...

Zebedee is a small hand-held device that consists of a lightweight LiDAR scanner with 30m (100ft) maximum range and a industrial-grade MEMS inertial measurement unit (IMU) mounted on a simple spring mechanism. As an operator holding the device moves through the environment, the scanner loosely oscillates about the spring, thereby producing a rotation that converts the LiDAR's inherent 2D scanning plane into a local 3D field of view. With the use of proprietary software, the range measurements can be projected into a common coordinate frame to generate an accurate 3D point cloud in real-time. To achieve this result, the software must estimate the six degree of freedom (6DoF) trajectory of the scanner on top of the spring solely from ...

The development of the ZeeEye UAV provides environmentally friendly production and low-cost lightweight, durable proprietary CBM™ materials.

Technical Abstract:

As UAV technology is rapidly evolving to meet specific operational requirements, the ZeeEye combines three high power and money saving technologies which provide the ZeeEye extended flight endurance.

The ZeeEye UAV and launch platform is easily transported by one person ‘backpack’ style. The ZeeEye UAV is stored in its container which doubles as its launch platform. The UAV doesn’t need to be removed from its transporter/launcher prior to launch, as both wings of the UAV rotate forward and deploy automatically upon exiting its container. The command and control system is state-of-the-art with the ground control station stored in the transport ...
