Abstract: A design for the electrical infrastructure of a data center enables two different configurations to be utilized, including a distributed, redundant configuration that provides higher reliability and a non-redundant configuration that provides higher capacity. In the distributed, redundant configuration, each server in the data center draws power from at least two different power supply systems. This enables load shifting when a power supply system becomes unavailable, which can have the effect of increasing server reliability. In the non-redundant configuration, each server in the data center draws power from only one power supply system. Load shifting is not utilized in the non-redundant configuration, which eliminates the need to maintain reserve capacity and thereby increases capacity. Advantageously, it is possible to switch between these two configurations without making any internal changes to the data center other than modifying connections between sets of server racks and power buses.

Abstract: Apparatus and associated methods relate to a coaxial stream delivery device having an inlet section and outlet section in fluid communication via a plenum chamber. In an illustrative example, an inner radius of the plenum chamber may monotonically decrease distally along a longitudinal axis. The inlet section may include an inner tubular wall extending along the longitudinal axis. At least one bridge may extend radially inward from the inner tubular wall to coaxially align an inner conduit therewithin relative to the longitudinal axis. The at least one bridge may define a corresponding number of annular sector apertures bounded by the inner tubular wall and an outer wall of the inner conduit. Various embodiments may advantageously be disposed in a fluid path to coaxially align a therapeutic fluid stream entering the inner conduit within a sheath fluid stream entering the annular sector apertures.

Abstract: A system for managing a battery removal from an electronic device is provided. The electronic device includes a battery interface including multiple battery coupling contacts that engage with battery contacts of the battery in an installed position of the battery. A battery removal detector is configured to detect, based on signals received via the battery interface, an ongoing battery removal process during which first battery contact(s) are disconnected from corresponding first interface contact(s) while second battery contact(s) remain connected with second battery coupling contact(s), and in response, to output a battery removal signal. The system also includes a controller that receives the battery removal signal and, still during the battery removal process, controls a memory device of the electronic device to prevent or complete a defined operation (e.g., writing of persistent storage keys) prior to completion of the battery removal process, to thereby prevent a corruption of the memory device.

Abstract: Methods for data de-duplication and data augmentation are performed by systems and devices. A request for information is received over a network from a requestor by a host, and is provided to an information source for a response. The host retrieves first data from a data source associated with the request, and receives the response that includes second data associated with the request. The first and second data are aggregated by the host. The aggregated data is processed by the host to remove duplicate information/records. The aggregated data is processed by the host to augment eligible data fields to correct, supplement, and calculate the aggregated data through data augmentation. An updated response is then provided back to the requestor with augmented data tracking. Neural network models are also utilized by the host for data augmentation.

Abstract: Described here are devices for closing one or more tissues, and handles for controlling these devices. Generally, the devices described here comprise a snare loop assembly, wherein the snare loop assembly comprises a snare and a suture loop, and a handle for controlling the snare loop assembly. In some variations the snare loop assembly may comprise a retention member that may releasably connect the suture loop to the snare. In other variations the devices comprise one or more force-reducing suture locks to help prevent the suture loop from inadvertently disengaging from the snare loop assembly. In still other variations, the excess-suture management features. The handles described here may be configured to remove excess suture from a suture loop, and may also be configured to release the suture loop from the snare loop assembly.

Abstract: A modular tent frame system comprises a number of folding frame elements which permit the shelter to be rapidly deployed in extreme environmental conditions. Telescopically sliding legs permit the tent frame to be unfolded, and the tent fabric attached to the frame, which the frame is on the ground and the tent can then be raised by sliding the outer leg elements up the inner leg elements to thereby raise the tent to the desired height, even in high winds.

Abstract: Systems, and methods relate to a medical device receiving a treatment parameter operating point within a first operating region defined by a first set of operating points for which automatic incremental adjustment of a parameter in the current operation is permitted. In an illustrative example, incremental adjustment may use artificial intelligence based on patient feedback and sensor measurement of outcomes. Some exemplary devices may receive a request to alter the current treatment parameter operating point to a second treatment parameter operating point outside the first operating region and in a second operating region in a known safe operation zone, bounded by a known unsafe zone unavailable to the user. In the second operating region, some examples may restrict the step size of incremental adjustments requested by the user. Data may be collected for cloud-based analysis, for example, to facilitate discovery of more effective treatment protocols.

Abstract: According to one aspect, a hybrid vehicle-to-grid and mobility service request system includes a receiving module, a transport module, a charging module, and a grant module. The receiving module receives a transport request and a vehicle-to-grid (V2G) request. The transport request is associated with transport from an origin to a destination using a vehicle. The V2G energy request is associated with providing charge from the vehicle to source equipment at a charging location. The transport module determines a first numerical value associated with remuneration for the transport. The charging module determines a second numerical value associated with remuneration for providing the charge. The grant module compares the first numerical value associated with the transport request to the second numerical value associated with the V2G energy request. The grant module grants the transport request or the V2G energy request based on the comparison.

Abstract: Apparatus and associated methods relate to a catheter manipulation handle with user interface controls for steering a catheter in situ while providing an augmented (e.g., motorized, powered and tunable precision steering, and perforation safeguards) control and feedback user experience. In an illustrative example, the catheter manipulation handle may provide motor assisted operation to automatically rotate and/or deflect a distal tip of the catheter to steer and guide the distal tip to a target location in the patient's vasculature system. The augmented feedback may include, for example, haptic feedback via the handle. Haptic, audible, and/or visual feedback via the handle may indicate, for example, proximity or engagement of the distal tip with sensitive tissue. In some examples, the handle's augmented operation may advantageously amplify feedback signals to enhance the user's perception of the patient's safety with respect to the safe passage of the distal tip through the patient's vasculature.
