Abstract:
A representative method for manufacturing a highly-laminated magnetic inductor core includes: depositing at least a first layer of a ferromagnetic material; depositing at least a first layer of a sacrificial conductive material; depositing a support structure formed of a ferromagnetic material; and removing the sacrificial conductive material, thereby leaving the at least first layer of ferromagnetic material mechanically supported by the support structure.

Abstract:
The present invention determines the resonant frequency of a sensor by adjusting the phase and frequency of an energizing signal until the frequency of the energizing signal matches the resonant frequency of the sensor. The system energizes the sensor with a low duty cycle, gated burst of RF energy having a predetermined frequency or set of frequencies and a predetermined amplitude. The energizing signal is coupled to the sensor via magnetic coupling and induces a current in the sensor which oscillates at the resonant frequency of the sensor. The system receives the ring down response of the sensor via magnetic coupling and determines the resonant frequency of the sensor, which is used to calculate the measured physical parameter. The system uses a pair of phase locked loops to adjust the phase and the frequency of the energizing signal.
Abstract:
A surface micromachined electromagnetically radiating antenna includes a coplanar waveguide on a ground plane coated substrate having a conductor path. The conductor path is coupled to a monopole conductor, which has a generally-cylindrical backbone erected vertically from the substrate and a metal layer deposited on the backbone at a predetermined thickness. The antenna may be fabricated by depositing an epoxy on the ground plane coated substrate to a predetermined depth and according to a pattern. The epoxy is exposed to an ultraviolet source that develops one or more columns according to the pattern. A seed layer of metal may be formed on the developed column. A conductive metal is electrodeposited over the column surface to produce the monopole antenna. Other antenna may be created by adding monopoles and/or conductive metal patches and/or strips that are positioned atop the monopoles and elevated from the substrate.
Abstract:
A gas species monitoring system includes a laser, a fiber amplifier configured to receive an input signal from the laser and generate an amplified signal, and a variable optical attenuation system configured to receive at least a portion of the amplified signal and generate an attenuated signal for delivery to a measurement point, where the measurement point includes a gaseous fluid. The system further includes a detector configured to receive and process a signal from the measurement point so as to obtain a measured signal that correlates with the presence of a gas species within the gaseous fluid at the measurement point, and a processor in communication with at least the variable optical attenuation system and the detector. The processor controls the variable optical attenuation system based upon the measured signal.
Abstract:
A system and method for controlling the surface and/or volume of a digital clay device is provided. One embodiment, among others, is a method comprising the following steps: determining a desired position of a skeleton structure portion residing in the digital clay device, determining a volumetric change of fluid residing in a bladder, the determined volumetric change corresponding to the determined desired position of the skeleton structure portion, opening a micro-electro mechanical systems (MEMS) valve so that the fluid flows through the MEMS valve thereby causing the determined volumetric change of the fluid, and adjusting a position of the skeleton structure portion corresponding to the desired position of the skeleton structure portion, the position adjustment caused by a force generated by the bladder on the skeleton structure portion when the volume of the bladder changes in response to the determined volumetric change.

Said collapsible container further includes a rigid non-collapsible portion at the top separated into two separate portions, the first portion being the top of said collapsible diaper storage area and the second portion being a discrete independent separate storage area for containing treated or medicated diaper wipes. Said second diaper wipe area having its own separate access area including a hinge and a depression or tab to access the sheets of said diaper wipes.
Abstract:
This invention is a rim shield for covering an automobile rim and providing a seal between a flange of the automobile rim and a sidewall of the tire around the rim. The rim shield has a circular shaped body with a handle positioned on the side of the body and a channel formed along a periphery of the body on its bottom side, or the side that faces the rim. The channel houses an O-ring that is shaped in a manner that allows the O-ring to seal the space between the sidewall and the flange. Once in this position, the rim shield can be rotated using the handle in a secure seal between the O-ring and space defined by the sidewall and flange.
Abstract:
The invention concerns a method of removing encapsulating material from encapsulated particles deposited onto a substrate. According to the method, a substrate is used which is capable of facilitating said removal of encapsulating material. The particles may be nanoparticles. In particular, the substrate-facilitated removal may result in sintering of the particles. The invention provides a novel way of functionalizing electronic structures using particulate matter and for conveniently producing e.g. printed electronics devices.
