Abstract: Examples of circuits and amplifiers include recirculation circuitry to reduce or cancel error currents produced by target bipolar junction transistors (BJTs). In an example, first recirculation circuitry is coupled to the base of a first signal-conveyance BJT and to one of the collector or the emitter of the first signal-conveyance BJT; second recirculation circuitry is coupled to the base of a second signal-conveyance BJT and to one of the collector or the emitter of the second signal-conveyance BJT; and biasing circuitry is coupled to the first and second recirculation circuitry. The recirculation circuitry may be implemented with BJTs or MOSFETs. Configurations are provided in which error current(s) are recirculated between the base and collector/emitter node of each target BJT.

Abstract: Systems and methods for managing the allocation of incoming charge power between an on-board power supply power output and HV battery power input. An electric vehicle (EV) may be used to provide power to one or more electrical devices connected to an on-board power supply of the EV. When the EV is connected to a charging device, a rate of charge may be determined. An allocation of the incoming charge power from the charging device may be determined as between a high voltage (HV) battery of the electric vehicle and the on-board power supply of the electric vehicle. Power may be simultaneously provided to the HV battery and the on-board power supply.

Abstract: A method executes at a computing device having one or more processors and memory. The device identifies a set of objects for a data visualization platform, each object in the set of objects representing a database, a data source, a table, a data field, a user, a visualization worksheet, or a calculated field. The device generates a data model from the set of objects. Each object of the set of objects is represented as a node in the data model and each directed edge in the data model identifies a relationship between a pair of objects. The device generates one or more shortcuts in the data model according to object types of the objects in the set of objects. Each shortcut represents a relationship, between a respective pair of objects, not represented by a directed edge. Then the device stores the data model, including the generated shortcuts, in the memory.

Abstract: A dilution refrigerator is provided. The dilution refrigerator includes a plurality of thermalization plates configured to be cooled to a plurality of temperatures, and a first thermalization plate of the plurality of thermalization plates includes an integrated heat exchanger. The integrated heat exchanger includes channels formed in the first thermalization plate, and the channels are configured to allow helium to flow through the first thermalization plate during operation of the dilution refrigerator to improve heat exchange and cooling power of the dilution refrigerator.

Abstract: A temporary tattooing ink is produced from concentrated genipin. In one embodiment, the concentrated genipin forms part of a solution. In another embodiment, the genipin is provided in a gel form which also includes a solvent and a thickening agent. Finally, an applicator is described into which genipin may be embedded for applying to a user's skin.

Abstract: Controlling charging of connected devices is provided. Presence of a target connected device is detected using a wireless transceiver of a vehicle. Settings indicative of how to charge the target connected device via a power connector of the vehicle are received a user interface presented to an HMI of the vehicle. Data packets from the target connected device indicative of a current state of charge of the target connected device are received using the wireless transceiver. The target connected device is charged from the power connector in accordance with the settings and the current state of charge.

Abstract: Upon detecting an accumulation of snow on a driving surface, a driving path from a first location to a second location is identified. A vehicle is operated from the first location to the second location and then to a third location that is identical to or proximate to the first location.

Abstract: A computer includes a processor and a memory storing instructions executable by the processor to receive data indicating that an electric vehicle is in an enclosed space; in response to receiving the data, instruct window actuators of the electric vehicle to open windows of the electric vehicle; and in response to receiving the data, instruct a heater of the electric vehicle to generate heat.

Abstract: Introduced here is a technology that enables a merchant to create customer-targeted, customized communications by use of a merchant platform executing on a financial service system. The merchant platform generates content for communications that is based on a particular customer segment. The customer segment includes one or more groups of customers segmented based on one or more attributes associated with each group of customers. An attribute is determined based on data collected by the financial service system, where the data is related to transaction data of a plurality of merchants.

Abstract: An example method for offline data synchronization to generate a representation of a space includes: localizing a data capture device in the space; detecting, by the data capture device, a nearby additional data capture device; in response to detecting the additional data capture device, establishing a communications channel to the additional data capture device; generating data representing the space; generating synchronization data based on the generated data; and sending the synchronization data to the additional capture device via the communications channel.

Abstract: A knife block and storage system are provided. The knife block includes a block body and an elongate slot formed in the block body. In some configurations, the elongate slot extends from the top surface and along a side surface. The knife block also may include a notch disposed in a top surface that is configured to receive and mate with a bolster of a first kitchen knife. The elongate slot is typically sized and shaped to accommodate a kitchen knife within the block body and is configured to permit removal of the kitchen knife from within the block body by sliding a blade of the kitchen knife out of the elongate slot through the side surface or by removing the knife blade through a portion of the elongate slot in the top surface.

Abstract: Systems for processing articles are essential for semiconductor fabrication. In one method of controlling gas flow, a processing system is provided, the processing system having first and second fluid supplies. The first fluid supply is coupled to a first apparatus for controlling flow and the second fluid supply is coupled to the second apparatus for controlling flow. The first process fluid is then delivered to a process chamber via outlet of the first apparatus for controlling flow. The first process fluid is also bled via a bleed port of the first apparatus for controlling flow. The flow rate of the first process fluid through the bleed port is controlled at a first flow rate which is less than a first threshold.

Abstract: This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with an outer wrap. In one embodiment, a pipe includes an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. The pipe also includes an outer wrap applied to the outer wall. The outer wrap may include fibers and plastic. The outer wrap may span the corrugation crests producing a smooth outer surface.
