Abstract: A system provides video files of a participant participating in an activity at a facility, the system comprising a plurality of smart cameras, each associated with a facility location and including an image sensor, optical elements, processor-executable instructions in first memory, second memory for storing captured video, and network transceiver circuitry; a cloud-based storage server for receiving and storing video content from the smart cameras; and a cloud-based control server that, upon user command to generate a participant video file at a specified location, directs at least one associated smart camera to assemble a video file from stored content and upload the generated file to the cloud-based storage server.

Abstract: Improved cooling modules and methods are configured to recirculate the liquid coolant fluid inside the cooling modules so that the same liquid cooling fluid impinges the surfaces of the heat-generating electronic components (or cooling plates in thermal communication with the heat-generating electronic components) multiple times before exiting the cooling module, thereby allowing a given flow of coolant fluid to be re-used several times over. With each re-use of the coolant fluid, the flow rate demand drops, reducing infrastructure required to achieve higher performance in direct and indirect micro-convective impingement cooling applications.

Abstract: A heat exchanger operable to condition air using a liquid desiccant. The heat exchanger includes an airflow inlet, an airflow outlet, heat exchange structures positioned between the airflow inlet and the airflow outlet, and a mesh screen positioned at the airflow outlet. Each heat exchange structure has a surface for flow of the liquid desiccant. The mesh screen selectively removes entrained liquid desiccant from the air.

Abstract: A dance shoe having an upper and an underfoot portion, the underfoot portion includes a sole shank, consisting of a relatively rigid structure, extending longitudinally in the shoe over at least a forefoot portion of the shoe and at least partially over a midfoot portion. The sole shank has at least one hinge with a unidirectional stop disposed widthwise in the sole shank. The sole shank covers at least the forefoot portion of the underfoot area and it locks to support plantar flexion and hinges to facilitate dorsiflexion of the foot. To facilitate en pointe movements, the sole shank may be coupled to a rigid distal part of the shoe, such as a toe box. The inventive subject matter is also directed to dance shoes, as well as the sole shanks themselves, and to methods of making the sole shanks and using the sole shanks in assemblies.

Abstract: Systems and methods for item recommendation are described. Embodiments of the present disclosure receive input indicating a relationship between a user and a first content item; generate a knowledge graph based on the input, wherein the knowledge graph comprises relationship information between the user and a plurality of content items; generate a first feature embedding representing the user and a second feature embedding representing a second content item of the plurality of content items based on the knowledge graph, wherein the second feature embedding is generated using a first modality for a query vector of an attention mechanism and a second modality for a key vector and a value vector of the attention mechanism; compare the first feature embedding to the second feature embedding to obtain a similarity score; and recommend the second content item for the user based on the similarity score.

Abstract: A sock shoe has a single layer of base fabric having a volumetric configuration for receiving at least a forefoot portion of a user's foot. The sock shoe is configured with an upper portion for receiving a top portion of the user's foot and a bottom portion for receiving a bottom portion of the user's foot. The base fabric has a knit or woven structure that is resiliently elastic. An elastomeric coating is fused to the base fabric in a single-layer unitary structure to provide at least two of: (i) a retention function, (ii) a durability/foot protection function, (iii) a grip or anti-slip function, and (iv) an outsole function. The bottom portion having an outer-facing, ground-contacting surface and an inner-facing, foot-contacting surface, the ground-contacting surface including at least one outsole portion being formed of the fused elastomeric material, and the inner-facing, foot-contacting surface being formed of the fused elastomeric material.

Abstract: In one possible embodiment, the inventive subject matter is directed to a foot covering, comprising: a thin, flexible compartment for receiving a foot. The compartment has a forefoot section, a midfoot section, and a rearfoot section of selected rigidity. The compartment has a top surface for securing the foot and a ground-facing surface having a sole divided into at least two portions comprising (1) a forefoot portion and midfoot portion and/or (2) a midfoot portion and a rearfoot portion. At least one sole portion comprises a midfoot portion disposed between a forefoot portion and/or a rearfoot portion. In the foot covering, each pair of sole portions is divided along a flexural line running generally transverse to the longitudinal axis of the foot.

Abstract: A three-way heat exchanger for a liquid desiccant air-conditioning system and method of manufacture. The heat exchanger includes a plurality of panel assemblies. Each panel assembly has a frame bordering a given space. The frame includes desiccant inlet and outlet ports and heat transfer fluid inlet and outlet ports. Two plates joined to the frame define a heat transfer fluid channel in the given space. The heat transfer fluid inlet and outlet ports are in fluid communication with the heat transfer fluid channel.
