    Abstract: A system for transmitting data through a string of downhole components. In one aspect, the system includes first and second magnetically conductive, electrically insulating elements at both ends of the component. Each element includes a first U-shaped trough with a bottom, first and second sides and an opening between the two sides. Electrically conducting coils are located in each trough. An electrical conductor connects the coils in each component. In operation, a varying current applied to a first coil in one component generates a varying magnetic field in the first magnetically conductive, electrically insulating element, which varying magnetic field is conducted to and thereby produces a varying magnetic field in the second magnetically conductive, electrically insulating element of a connected component, which magnetic field thereby generates a varying electrical current in the second coil in the connected component.

    Abstract: An apparatus for distributing data using a short-range wireless interconnection protocol for electronic devices includes a processor communicatively connected, using a communication bus, to a number of originator antennas, each of the number of originator antennas communicating with an originating device, a plurality of device antennas, communicatively connected to the communication bus, each of the plurality of device antennas communicating with a number of client devices, and a non-transitory storage medium. The non-transitory storage medium includes a receive module, a session identify module, and a send module. The receive module receives a data packet using one of the number of originator antennas. The session identify module identifies at least one communication session with at least one remote device associated with one of the plurality of device antennas. The send module sends the data packet to the at least one remote device associated with one of the plurality of device antennas.

    Abstract: The apparatus described herein may include a base plate, one or more walls, one or more obscured feature detectors, one or more obscured feature indicators, a controller, and a power source. The base plate may include one or more surface-mounting structures that mount the apparatus to a surface. The walls may extend at least partially perpendicularly from the base, and may include one or more device-mount structures that mount one or more removable devices to the walls. The detectors and indicators may be connected to the base, the walls, or both. Each detector may correspond to at least one of the surface-mounting structures. Each indicator may correspond to at least one of the detectors. The controller may be electrically connected to the detectors and the indicators. The controller may activate the indicators as the detectors detect a feature obscured behind a surface adjacent to the detectors.

    Abstract: The invention is a modular building component with rod-based dimensions. The modular building component comprises a prismatic box structure. A number of the prismatic box structures are placed side by side horizontally to create a ceiling and a floor with rod-based dimensions. The ceiling and the floor function as components of a building with rod-based dimensions. The building may also have walls that are also prismatic box structures with rod-based dimensions. Two or more of the buildings can be placed side by side to fill equal portions of an entire width of a perfect-acre lot. The buildings that fill an entire perfect-acre lot lead to a sustainable community design, given that no space is wasted. The rod-based building components are properly dimensioned for quickly assembling these optimally sustainable buildings.

    Abstract: The tandem differential mobility spectrometer (DMS)-ion modulator instrument provides improved resolution relative to traditional DMS for molecules with larger masses. The instrument includes multiple ion-bunching electrodes, each with an AC field synchronized to the transit time of the ion flow which is positioned downstream of a DMS. The ion bunching electrodes produce each a mobility-dependent modulation of the ion current. The ratio of AC to DC current provides a measure of the mobility of a large ion, even if it has little differential mobility, thereby extending the useful range of mobility characterization of a DMS system. The instrument does not require high voltages or high frequencies. Modulation before DMS separation or between tandem DMS separations produces a variable range of analyte and reactant ion densities as well as spatially separating negative and positive ions to reduce ion recombination.
