Acceleration Sensor Enables New Robotics Applications

The Inclinos 3DS inclination and acceleration sensor, based on thermodynamic effects, exhibits no hysteresis in response signal (output lag). A power distribution of four heaters is controlled by a closed loop, and the temperature of each heater is constantly affected by any acceleration. The sensor has no moving parts, no inertial mass, and offers high responsivity from the idle position. Depending on the angle, the Inclinos measures 360-degree inclination on two axes.

Water-Based Cooling Fluid Reduces Corrosion

A water/propylene glycol-based formulation acts as a heattransfer medium and reduces the corrosion of sensitive metals by 10x to 100x in heat exchangers, radiators, cold plates, and associated plumbing. The water-based cooling fluid can be used with equipment containing a variety of metals, while still providing freeze protection.

Dissolution Device

To enhance transportability and shelf life, many drugs and pharmaceuticals are distributed as freeze-dried formulations. The formulations must be dissolved before they can be injected. A client therefore seeks a new device or container that helps lyophilized preparations dissolve rapidly and completely with diluents such as water. It is possible to improve dissolution by longer or faster stirring, or by heating, but the proposed solution must not apply heat or create bubbles. The formulation, intended for injection, needs to work with a variety of powdered drug types, thus showing versatility.

Grab-Bars and Safety Grips

Because of their weight and the weight they bear, most grab-bars must be installed permanently in a home, usually by drilling through the wall material and into a wall stud. In the case of grab-bars installed in a tub enclosure or shower, a permanent hole may need to be drilled through ceramic tile, thus making a change to the material that is difficult to patch if the bar is removed later. A company desires a grab-bar solution that can attach to any surface, including tile or drywall, and later be removed without marring the underlying surface. The grab-bar must support up to 250 pounds and include a consumable or renewable feature.

Manufacturing Process Supports Cost- Effective TPM Production

Transverse Flux Machines (TFMs) are brushless motors and generators that use permanent magnets. A TFM’s direction of magnetic flux is perpendicular to the direction of force, instead of parallel to it, as in a standard electric motor or generator. The machines are also inherently lighter, smaller, more power dense, and more powerful.

Land-Intensive Solar Tracker Generates Photovoltaic Power

A solar tracker enables the construction of independent power sources and a micro-grid. The mechanism of the land-intensive system has two independent virtual axes for azimuthal moving and altitude moving. After the solar panel is aligned, the tracker drives it to move from east to west until the amount of change of the Sun’s altitude reaches a specific level.

Adhesion Prevention for Sheet Goods

A company produces and stacks sheet goods that have a naturally viscous and sticky surface material. The sticky material is applied at about 480 °F. During application, the coating has a specific gravity of 1.03 to 1.70, and a viscosity of >5000 cps. A release material needs to be applied to the substrate material during production so that the sheets do not adhere during shipment and storage. Even at 480 °F, the coating cannot decompose, melt, mix, delaminate, or combine with the underlying substrate. The organization is open to any application method, such as roll-to-roll, spray, paint-on, or application via tape.
