Abstract:
This publication discloses a method for forming electrically conducting structures on a substrate. According to the method nanoparticles containing conducting or semiconducting material are applied on the substrate in a dense formation and a voltage is applied over the nanoparticles so as to at least locally increase the conductivity of the formation. According to the invention, the voltage is high enough to cause melting of the nanoparticles in a breakthrough-like manner. With the aid of the invention, small-linewidth structures can be created without high-precision lithography.
Abstract:
Systems and methods for arresting vehicles or other moving objects are detailed. The systems may be bi-directional, so as to arrest vehicles on either side of a barrier. They additionally may be reset for reuse relatively rapidly following deployment.
Abstract:
An LED light string employs a plurality of LEDs wired in block series-parallel, where the one or more series blocks, each driven at the same input voltage or rectified AC input voltage as the source voltage (110 VAC or 220 VAC), are coupled in parallel. This voltage matching requirement for direct AC drive places fundamental restrictions on the number of diodes on each diode series block, depending on the types of diodes used. The same method that apply to matching the sum of the LED lamps (VAC values) to the AC input, or applied voltage in an AC circuit apply to matching the sum of the LED lamps (VP values) to the full-wave or half-wave rectified AC (VP) voltage applied. Filtering capacitors may also be employed.
Abstract:
A sensor suitable for in vivo implantation has a capacitive circuit and a three-dimensional inductor coil connected to the capacitive circuit to form an LC circuit. The LC circuit is hermetically encapsulated within an electrically insulating housing. An electrical characteristic of the LC circuit is responsive to a change in an environmental parameter.
Abstract:
A sensor for wirelessly determining a physical property within a defined space comprises an electrical resonance and has a high quality factor Q. The quality factor Q is sufficiently high that a signal generated by the sensor can be received outside the defined space. The sensor may optimally have a dielectric coating.
Abstract:
An electromagnetically coupled hermetic chamber includes a body defining a hermetic chamber. A first conductive structure is disposed within the hermetic chamber, and a second conductive structure is attached to the body outside of the hermetic chamber. The first conductive structure is electromagnetically coupled to the second conductive structure without direct electrical paths connecting the first and second conductive structures. Thus the first conductive structure can be coupled to external electronics without the need for electrical feedthroughs or vias that could compromise the integrity of the hermetic chamber.
Abstract:
A pressure cavity is durable, stable, and biocompatible and configured in such a way that it constitutes pico to nanoliter-scale volume. The pressure cavity is hermetically sealed from the exterior environment while maintaining the ability to communicate with other devices. Micromachined, hermetically-sealed sensors are configured to receive power and return information through direct electrical contact with external electronics. The pressure cavity and sensor components disposed therein are hermetically sealed from the ambient in order to reduce drift and instability within the sensor. The sensor is designed for harsh and biological environments, e.g. intracorporeal implantation and in vivo use. Additionally, novel manufacturing methods are employed to construct the sensors.
Abstract:
The present invention provides a method of processing data having one of two types. In particular, the first type of data is formed from a respective data instance, whereas the second type is formed from a number of data elements. In particular, if the data is the first data type, the method includes defining one or more associations between the data instance and any one of a predetermined model, keywords and, other data instances, storing the data instance in a store and storing knowledge data representing the defined associations in the store. In contrast if the data is the second data type, the method includes defining a data instance, the data instance being formed from one or more of the data elements. The method outlined above for the first type of data is then performed for the defined data instance.
Abstract:
A Bulk Mail Container (BMC) unloader uses a simple crossed four bar-linkage to move a predetermined point on a BMC unloader in a substantially straight line while the overall BMC unloader rotates about that predetermined point so as to upend the BMC container. This takes advantage of the crossed four-bar's substantially straight-line motion over a limited range of its motion, as well as the rotational motion of the particular unloader link disclosed herein. This is advantageous for unloading. In use, a BMC container is simply rolled into the BMC unloader, and the entire combination of the BMC container and BMC unloader is then actuated to produce substantially straight line motion along a suitably selected “center” point of the BMC unloader while the overall combination rotates about the center point so as to upend the BMC for unloading.
