Abstract: A high temperature heater lamp including a ceramic envelope is disclosed. The ceramic envelope is substantially infrared transparent and is composed of a refractory ceramic. The heater lamp also includes two lead wires communicatively coupled via a filament. The filament is enclosed within the ceramic envelope, which is evacuated. The heater lamp may include at least two metallic IR shields within the ceramic envelope, at least one located on either side of the filament. The filament may be tungsten, a carbon filament, or molybdenum. At least one end of the ceramic envelope may be sealed with a metal cap affixed to the ceramic envelope by a high vacuum sealant. The heater lamp may be configured to operate at above 1500° C. The ceramic envelope may have a wall thickness less than 1 mm thick.

Abstract: A photoinjector system containing modularly-structured waveguide-mode launcher, which is reversibly connected to the RF gun (containing a tubular construction formed with disattachably-affixed to one another structurally-complementary halves); and a solenoid magnet in operation enclosing such tubular structure in a central hollow. The resulting quality, power, and frequency rate of operation as well as cost of manufacturing and operation of the system are superior as compared with those of a related art system.

Abstract: Systems, methods, and apparatuses for implementing a geo-demographic zoning optimization engine are disclosed. According to an exemplary embodiment, there is a system executing at a web platform, in which the system includes: a memory to store instructions; a set of one or more processors; a non-transitory machine-readable storage medium that provides instructions that, when executed by the set of one or more processors, the instructions stored in the memory are configurable to cause the system to perform operations for designing sectioned mappings for a geo-demographic region, the operations including: executing instructions via the processor to implement a receive interface at the web platform; exposing the receive interface to users of the web platform; receiving, at the receive interface, geographic information system (GIS) data defining a plurality of district boundary spatial layers for a plurality of land parcels representing districts located at least partially within the geo-demographic region; creating a plurality of zones by overlapping the plurality of district boundary spatial layers; combining separate subsets of the plurality of zones into temporary exclusive regions; optimizing a number of precincts for each of the temporary exclusive regions by combining two or more of the temporary exclusive regions into a number of precincts; in which the optimizing comprises executing an algorithm based on hierarchical objectives configured to minimize splitting precincts that contain more than one district of any type, subject to user-selected input parameters operating as constraints; and generating a design plan map with optimized number, shape, size, and boundaries defining every precinct of the design plan map outputted from the web platform to a user interface. Other related embodiments are disclosed.

Abstract: A system can include a multi-material fluid having a mixture of a first material and a second material. The system can also include a first vessel into which the multi-material fluid is disposed. The system can further include a first sonication device disposed, at least in part, in the multi-material fluid in the first vessel. The first sonication device, when operating, can emit ultrasound waves into the multi-material fluid. The ultrasound waves separate the first material and the second material from each other in the first vessel.

Abstract: A device for passive collection of atmospheric carbon dioxide is disclosed. The device includes a release chamber having an opening and a sorbent regeneration system. The device also includes a capture structure coupled to the release chamber, having at least one collapsible support and a plurality of tiles spaced along the collapsible support. Each tile has a sorbent material. The capture structure is movable between a collection configuration and a release configuration. The collection configuration includes the capture structure extending upward from the release chamber to expose the capture structure to an airflow and allow the sorbent material to capture atmospheric carbon dioxide. The release configuration includes the collapsible support being collapsed and the plurality of tiles being sufficiently enclosed inside the release chamber that the sorbent regeneration system may operate on the plurality of tiles to release captured carbon dioxide from the sorbent material and form an enriched gas.

Abstract: Some embodiments of the present disclosure provide a method that includes colliding a laser with an electron beam to produce backscattered x-rays while the electron beam is traversing a circular arc. This backscattering process is inverse Compton scattering (ICS). ICS x-rays are emitted in the same direction as the electrons. Because this ICS direction is changing as a function of time, the position of the x-ray beam on a detector will change depending on the timing of electron/laser collision. This position change is easily detected and converted to a timing measurement sensitive at the femtosecond scale, converting a very difficult timing measurement of laser pulse, electron pulse, and x-ray pulse synchronization into a simple and robust position measurement.

Abstract: A self-powered voltage ramp for photovoltaic module testing provides a robust circuit for the measurement of current-voltage curves. A resistor and capacitor form a timer circuit to control a gate of a power transistor and give a linear voltage sweep from a short circuit (e.g., zero volts) to an open circuit voltage VOC. The sweep rate can be varied by adjusting the resistor value. Additional enhancements prevent oscillations within the circuit, maintain a voltage of the power transistor within its design specifications, and allow for the measurement of single cell mini-modules. Additional circuitry can characterize the photovoltaic module based on the measurement data. Measurement accuracy is within 1% of a laboratory supply for measurements of maximum power, short circuit current, and open circuit voltage.
