Waterproof membrane is vapor-permeable but non-porous
Procter & Gamble has developed a proprietary, non-porous vapor-permeable membrane (VPM) that is flexible, inexpensive, and highly versatile. The result is a lightweight, ultra-thin thermoplastic composition ideal for personal hygiene products, textiles, and medical products. The fundamental product is composed of a hydrophilic thermoplastic polymer mixed with one of several plasticizers. Conventional breathable waterproof fabric barriers primarily use microporous materials and can be very effective. However, there is a trade-off -- the more effective the barrier, the less breathable the fabric. P&G's VPM technology uses a nonporous material that actually transfers moisture vapor through diffusion. The result is a softer and more drapable fabric that exhibits about fifty percent greater breathability when compared with the best-in-class microporous fabric at comparable levels of waterproofness.

Cooling system for self-contained laser head
The cooling system described here is capable of cooling a laser, laser power supply, and a laser light valve from one single circulating unit. The differing degrees of cooling needed by the different components are taken into account and one cooling system takes care of the different thermal loads. The cooling system avoids premature laser failure due to overheating. The system also provides thermal protection for a laser in case of cooling failure. The technology is and has been sold in commercial systems (platesetters).

Airflow sensor and transmitter
The impeller-in-a-tube design of this airflow sensor and transmitter enables highly accurate measurement over the entire surface of the opening, thus making it insensitive to the airflow pattern. The curve of the blade angle over the length of the blades is mathematically defined to produce a linear relation between the airflow and the rotation speed. Units are available for measuring up to 6 cubic meters/second through 0.80 meters diameter. Smaller units have been in use for several years. The core of the unit is a special shaped impellerblade ensuring low maintenance and high accuracy for relatively low costs. The standard output is a pulse signal; other signals are possible. The transmitter can be supplied, combined with a throttle valve, making it a high accurate airflow control unit.

Calcium phosphate ceramic powder for cell transfection
These ceramic powders transfect cells both in vitro or in vivo with a good yield when compared to the other non-viral methods for cell transfection. These materials are perfectly biocompatible. They have been used in orthopedic surgery for more than two decades. They are totally degradable when implanted in the body. They are, furthermore very cheap to produce. Prototypes done. Manufacturing scale up done. CE marking in course. In vitro testing on monolayers, 3D grown cells, tissue culture. In vivo testing in rabbit bone.

Polymers benefit from moldmaking technology that requires no demolding agent
New and fast method for building molds that require no demolding agent at all. The technology features unusual advantages such as high-detail finished pieces without mold polishing or detail carving; also resulting pieces are ready for painting/bonding without any previous process, thus optimizing the piece's bonding/painting properties. Environmentally friendly.

Determining the speed of ultrasound in tissues
In ultrasound imaging techniques ultrasound waves are sent into tissue and the ultrasound waves that are reflected by various tissues are detected. Photoacoustic tomographic imaging is a hybrid imaging technique that uses pulsed light to induce ultrasound. This ultrasound arises due to thermoelastic expansion at positions where pulsed light is absorbed. The generated ultrasound is detected. A method has been developed and tested to -- on-line -- determine the speed of sound in tissue using an acoustic sensor working in reflection mode. The novel element in this technique is the processing of the signal. This specific signal-processing enables the technology to calculate the different velocities of the ultrasound waves in different tissues. The technique has been evaluated and tested in vitro. It is considered an algorithm that requires further development and testing before it can be applied.

Projection systems and components
This portfolio includes patents for front and/or rear LCD projectors, DLP projectors, and LCoS projectors. Projection systems include light source, heat flow, optical engine, etc.; the patents' projection components include projection screen, beam splitting or combining device, polarization conversion components, etc., while the lens set patents include wide-angle lens set, zoom lens, etc. These technologies are being commercialized currently.

Electrolytic method for purifying gases
Remove electrolytically convertible impurities from gases and purify gases using an electrolysis cell as described in this technology. The cell has a fixed-bed electrode and a counterelectrode separated from it and designed as a gas diffusion electrode. In order to purify gas the fixed-bed electrode is operated as a trickle bed and the gas to be purified flows in concurrent or countercurrent flow to the electrolyte. In reductive purification hydrogen is supplied to the gas diffusion electrode and in oxidative purification oxygen is used.

Dehydrogenation of alkylaromatic compounds
This technology includes zero-valent copper on an aluminum borate solid supported catalyst composition, process for catalyst preparation, and a process for vapor phase dehydrogenation of alkylaromatic compounds to the corresponding alkenylaromatic compounds. The catalyst preparation uses an improved process of a combination of water and a volatile organic liquid having at least partial miscibility with water to yield a crystalline catalyst with high surface area and large pore sizes. This process eliminates the need to grind solid reagents to uniform size and to blend dry solids in order to obtain a homogeneous mixture in the preparation of the copper aluminum precursor, thus greatly simplifying the overall catalyst preparation. Projects are outside this organization's current strategy.

Plank rolls up for transport, entry into difficult workspaces
The unique design of Roller Bord provides a sturdy plank or work surface that rolls up to make it easy to maneuver into tight areas where long, linear planks can't go - such as around corners. Minimal storage is needed. If damaged, only the damaged section need be replaced. Extendable in the field to span wider distances. The development of this product is at the stage where the need of technical input from the plastics industry is required to define the make up and final compound needed for production.
