Abstract: A device holder assembly that includes a body and a housing coupled to the body. A drive assembly is rotatably coupled to the housing. A leg assembly that includes a first leg and a second leg is coupled to the housing. A first rack gear is coupled to the first leg and the drive assembly. A second rack gear is coupled to the second leg and the drive assembly. The drive assembly permits instantaneous movement of the first leg and the second leg. A first finger is rotatably coupled to the first leg and a second finger is coupled to the second leg. The first finger has a first finger outer surface and the second finger has a second finger outer surface that are generally coplanar with the body outer surface when the first finger and the second finger are in a retracted position.

Abstract: The disclosed embodiments include computerized methods, systems, and devices, including computer programs encoded on a computer storage medium, for generating terms of a search query based on a user's spoken utterances, identifying multiple cross-platform messages based on the generated terms, and to generating, via a presentation device, a single interface that enables the user to interact with identified messages. Based on a spoken utterance, the disclosed embodiments may determine user-specified search terms and/or criteria, and based on the user-specified search terms and/or criteria, may obtain cross-platform message data that corresponds to the search query. The communications device may generate one or more interface elements that describe corresponding ones of the cross-platform messages, which may be presented within a unified graphical user interface or voice-user interface by a communications device.

Abstract: An electronic assembly may include a chassis having electronic module mounting positions. Each mounting position may have associated therewith a chassis liquid dual-flow connector. A respective electronic module may be received in each electronic module mounting position and include a circuit board, a liquid cooling path associated with the circuit board, and a module liquid dual-flow connector coupled to the liquid cooling path and configured to be mateable with the chassis liquid dual-flow connector.

Abstract: An electronic assembly may include a chassis having electronic module mounting positions and respective electronic modules received in each electronic module mounting position. A respective retainer may be coupled between the chassis and each electronic module. Each retainer may include a retainer body coupled to the chassis, and a liquid coupling body carried by the retainer body and movable between retracted and extended positions permitting insertion and removal of the electronic module. The liquid coupling body may have a retainer liquid outlet and a retainer liquid inlet configured to engage a module liquid inlet and module liquid outlet, respectively, when moved from the retracted position to the extended position.

Abstract: A rail assembly includes assembly includes a fixed carriage and a clamping system. The fixed carriage defines a receiving area and a rail at least partially supported within the receiving area. The rail is slidable along an axis relative to the receiving area. The clamping system applies a clamping force on the rail within the receiving area. A movable assembly may be supported on the rail such that the movable assembly is movable along the axis relative to the fixed carriage.

Abstract: A portable urine collection system (200) may include a urine collection device, a conduit (217) in fluid communication with the urine collection device (212), a urine collection container (214) having an interior region, a pump (216), and a container support (202). The pump is in fluid communication with the urine collection container and is configured to pull a vacuum on the interior region of the urine collection container effective to draw urine from the urine collection device through the conduit into the urine collection container. The container support is configured to detachably secure to a wheelchair and support at least the urine collection container.

Abstract: The invention is a system for the in-situ monitoring of additive manufacturing. The system, without pre-calibration of a test sample, utilizes ultrasonic waves to conduct a layer-by-layer analysis of a three-dimensional component as it is being developed on a build plate. Resonant frequencies for each layer is measured and the difference between the resonant frequencies of consecutive layers are calculated to define a baseline frequency. Similarities or differences in baseline frequencies are used to validate the integrity of the layers of the component, and also to determine if structural inconsistencies exists. Based on these determinations, the system decides whether to continue printing or to halt printing.

Abstract: An online teaching method, including the steps of: under control of a control center of an online teaching system, identifying authentication and associating account with a student in response to a request of accessing to an online platform of the online teaching system from the student; providing teaching videos in stages which are cut into segments for the student; providing feedback information interacting between the student and a plurality of teachers; grading the student by analyzing the teaching videos that the student recorded; and determining the graduation of the student by the judgement of the student teaching others.

Abstract: A nutritional supplement includes a predetermined amount of an ATP increasing herbal component which includes species of cordyceps to increase a long-term internal ATP energy; a predetermined amount of L-theanine to increase a mental energy; and a predetermined amount of external energy stimulants including caffeine to provide a short-live external energy, which may be utilized as beverages, foods, supplements, and drugs so as to provide the absolute energy for all mammals including human beings, and pets such as dogs, cats, and rodents.

Abstract: Two or more plates, each having a matching alignment hole, are precisely aligned and mated together by an aligning and clamping device that includes: (a) a plurality of movable aligning fingers, retraction means for causing the aligning fingers to move into a retracted state where they occupy a first volumetric space sufficiently small to allow the two or more plates to be moved over the retracted fingers so as to have their respective alignment holes surrounding the retracted aligning fingers; (b) expansion means for use after the plates have been moved over the fingers, the expansion means urging the fingers to expand outwardly to occupy a second volumetric space greater than the first volumetric space such that the fingers begin to contact and begin to improve co-alignment between the surrounding alignment holes; and (d) clamping means for use after the alignment holes of the plates have begun to come into improved co-alignment, the clamping means applying a clamping force for clamping the two or more mate
