Abstract:
A tool provided that individually creates three-dimensional structural elements which are sequentially positioned into formation of a shaped object.
Abstract:
A circuit comprising an array of light emitting diodes (LEDs), and a layer of VSD material positioned to contact an input and an output of each LED in the array of LEDs, so as to protect each LED from both a forward surge and a reverse surge of voltage on the array of LEDs. The layer of VSD material is able to switch into a carrying current state in response to either of the forward or reverse surge exceed a characteristic voltage level (VCL) of the VSD material.
Abstract:
Methods of manufacturing nano-engineered carbon materials, such as carbon aerogels and carbon xerogels, and methods of manufacturing precursor solutions and sol-gels for making the same are provided. A method for manufacturing a precursor solution comprises programmed-addition of a cross-linking agent to a component mixture comprising a resorcinol compound. A method for manufacturing a sol-gel comprises subjecting a precursor solutions to at least one heat treatment. Methods for producing nano-engineered carbon materials from precursor solutions and sol-gels are also provided. Methods for using the nano-engineered carbon materials are also disclosed. The resulting nano-engineered carbon materials can be useful in a range of products including, supercapacitor applications, high-surface-area electrodes, fuel cells, and desalination systems.
Abstract:
Printed circuit boards including voltage switchable dielectric materials (VSDM) are disclosed. The VSDMs are used to protect electronic components, arranged on or embedded in printed circuit boards, against electric discharges, such as electrostatic discharges or electric overstresses. During an overvoltage event, a VSDM layer shunts excess currents to ground, thereby preventing electronic components from destruction or damage.
Abstract:
One or more embodiments provide for a composition that includes (i) organic material that is conductive or semi-conductive, and (ii) conductor and/or semiconductor particles other than the organic material. The organic material and the conductor and/or semiconductor particles are combined to provide the composition with a characteristic of being (i) dielectric in absence of a voltage that exceeds a characteristic voltage level, and (ii) conductive with application of the voltage exceeding the characteristic voltage level.
Abstract:
An electroplating process is performed using a substrate that includes a thickness of voltage switchable dielectric (VSD) material having photoactive components that are dispersed, mixed or dissolved in a binder of the VSD material. A pattern of conductive elements may be formed on the substrate by switching the VSD material from a dielectric state to a conductive state using, in part, voltage generated by directing light onto the thickness and VSD material.
Abstract:
A headlight glare safety device and method to enhance the night vision of the driver via the employment of a diffused red light beam onto the segment of a windshield through which a driver views oncoming traffic to offset and counter the glare of oncoming headlights.

Abstract:
A process for making a fibrous product using a binder based on a formaldehyde-containing resin and especially for making fiberglass insulation products, and to the fibrous products themselves, wherein the fibrous product is placed in a mass transfer relationship with a formaldehyde scavenger, such as by having a backing sheet affixed thereto and the backing sheet is coated or impregnated with a formaldehyde scavenger composition, or by isolating the insulation product in an enclosed space with a formaldehyde scavenger, with the result that the fibrous product exhibits a reduced level of formaldehyde emission.
