Abstract: A neuro-symbolic retrieval augmented generation hybrid method includes detecting an incomplete entigen group within a knowledge database. The incomplete entigen group includes entigens and one or more entigen relationships between at least some of the entigens. The incomplete entigen group represents knowledge of a topic. The method further includes obtaining additive content for the topic based on the incomplete entigen group and generating an additive entigen group based on the additive content. The method further includes updating the incomplete entigen group utilizing the additive entigen group to produce an updated entigen group. The method further includes indicating that the updated entigen group has an un-curated status when the additive entigen group conflicts with the incomplete entigen group.

Abstract: A method executed by a computing device includes determining a set of identigens for each widely-known word of a query to produce sets of identigens. A set of identigens of the sets of identigens represents one or more different meanings of a word of the query. The method further includes determining another set of identigens for a remaining word to produce an alternate set of identigens. The method further includes selecting an identigen for each set of identigens to produce a query entigen group. The method further includes matching the query entigen group to a set of response entigens to produce a response entigen group as a query response.

Abstract: The disclosed examples are directed to systems and methods for performing co-presence estimation. The systems and methods detect, by a first device associated with a first user, a beacon signal generated by a second device associated with a second user and generate co-presence information representing proximity between the first device and the second device based on detecting the beacon signal. The systems and methods select a graphical indicator from a plurality of graphical indicators of co-presence based on the generated co-presence information and present a proximity graphical user interface (GUI) comprising a map portion and a co-presence portion using the selected graphical indicator.

Abstract: A fuel injector for an internal combustion engine comprising an injection nozzle comprising a nozzle body with a nozzle bore; a valve needle assembly received within the nozzle bore and including a valve needle engageable with a seat region to control fuel delivery through an outlet of the injection nozzle; and a first actuator arrangement operable to apply an opening force to an engagement region of the valve needle assembly to cause an opening movement thereof. The first actuator arrangement comprises a first conductive coil mounted concentrically on a first body and a first armature configured to apply the opening force to the valve needle assembly. The first body comprises a first, radially inner region having a relatively high magnetic permeability and a second region having a relatively low magnetic permeability, the second region being disposed radially between the first coil and the first, radially inner region.

Abstract: A vaporizer includes a reservoir (or cartridge) to hold a precursor composition. The reservoir has a passageway that is configured to not allow the free flow of the precursor composition out of the reservoir at ambient temperatures. An infrared radiation source, when activated, heats the precursor composition reducing its viscosity. An entrainment passageway is in communication with an exterior end of the passageway such that when an air flow is induced to pass through the entrainment passageway, the air flow draws the heated precursor composition from the passageway entrains it in the air flow. The entrained precursor may be vaporized and/or further vaporized by heat from the infrared radiation source before being inhaled by the user.

Abstract: A fluorescence histo-tomography (FHT) method may include capturing, using an imaging device positioned with respect to a chamber of a slicing apparatus, images of a block face of a specimen retained within the chamber. The images may be captured in the visible and infrared or near-infrared spectrum. The method may include co-registering the images to form a combined image, and providing the combined image to an electronic display. In some implementations, the method may include positioning the imaging device away from the chamber, operating the slicing apparatus to expose a second block face of the specimen, and repositioning the imaging device with respect to the chamber.

Abstract: Embodiments disclosed herein provide a surgical console, a surgical cassette, and a method for utilizing an image sensor to acquire grayscale image(s) and an embedded microcontroller to then process the image(s) to decode the barcode and/or determine the current level of fluid within the surgical cassette. The image sensor is utilized to detect external light that comes into the field of view of the image sensor. A software algorithm stored within a microcontroller in the surgical console determines whether the potential is high for external light interference. If there is a high potential for external light interference, an advisory or alarm is generated to warn the user to remove the external light source or to turn the console away from the external light source. Once the user has removed the external light and then cleared the advisory, normal console operations and functions can resume.
