Macrospray® nozzles produce consistent mists at very low pressure. The nozzles have a uniformly distributed droplet size (10–30 μm Sauter Mean Diameter), which provides greater contact between deodorant, for example, and odorcausing particles or dust. Droplet size can be tuned for the degree of dust...

A patented, one-piece, fiber-reinforced plastic composite chassis, produced by sheet molding compression, uses a highglass-content vinyl ester composite structural material, toughened with urethane for fatigue and damage tolerance.

An organization needs an inexpensive device to deliver a pre-measured amount of liquid evenly to a surface. The applicator is intended for a single use, must be able to be sterilized after final assembly, and needs to hold enough liquid or gel to cover about 1 to 3 square feet of surface...

A torque-feedback mechanism must measure force, pressure, and displacement. The hybrid system or multi-part assembly requires haptic, visual, sound, temperature, or vibration feedback instruments. The technology may take the form of either a standalone sensor cube that flashes according to pressure, or a material that...

A document discusses a project in which a series of novel hybrid positive electrode materials was developed and tested in asymmetric capacitors with carbon negative electrodes. The electrochemical performance of the hybrid capacitors was characterized by cyclic voltammetry and a DC...

A document discusses a hyperspectral imaging instrument package designed to be carried aboard a helicopter. It was developed to map the depths of Greenland’s supraglacial lakes. The instrument is capable of telescoping to twice its original length, allowing it to be retracted with the door closed during...

The performance of a traditional diode pumped solid-state laser that is typically pumped with 808-nm laser diode array (LDA) and crystalline Nd:YAG was improved by using 885-nm LDAs and ceramic Nd:YAG. The advantage is lower quantum defect, which will improve the thermal...

A subaperture stitching interferometer system provides near-nulling of a subaperture wavefront reflected from an object of interest over a portion of a surface of the object. A variable optical element located in the radiation path adjustably provides near-nulling to facilitate...

Maxim Integrated Products (Sunnyvale, CA) offers the MAX44000, a digital ambient-light and infrared proximity sensor that detects light like a human eye. Designed using the company’s proprietary BiCMOS technology, the IC integrates three optical sensors, two ADCs, and digital functionality into a 2mm x 2mm x 0.6mm package.

A set of piezoelectric actuators weighs 4 to 50 times less than other robotic actuators in end-effectors, including hydraulic or solenoid devices. The small piezos use ultra-low power: 3 mA holding current at 6.8 VDC, 7.5 mW. The piezo technology is a scalable actuator moved by a pre-loaded piezo...

A new process produces microspheres of an extremely narrow size distribution and high homogeneity, measuring between 2 and 10 μm. The process can make the microscopic spheres from any material that can be polymerized; acrylic and styrene spheres have been...

A client seeks transformative technologies that will enable a variety of optical effects or hidden messaging to be created directly onto consumer products and its packaging. Reversible effects that are triggered by external stimuli, such as water (hydrochromic) and light (photochromic), are of interest. Solutions...

An organization must reduce the amount of plastic resin used in packaging, while maintaining the package’s structural integrity and functionality through the supply chain. It may be possible, for example, to inject air bubbles into plastic resin in such a way as to maintain container size, shape, and...
