Abstract: A phased-array includes, in part, N transceivers each including a receiver and a transmitter, and a controller. The phased array is configured to transmit a first radio signal from a first element of the array during a first time period, receive the first radio signal from a second element of the array, recover a first value associated with the radio signal received by the second element, transmit a second radio signal from the second element of the array during a second time period, receive the second radio signal from the first element of the array, recover a second value associated with the radio signal received by the first element, and determine a first phase of a reference signal received by the second element from the recovered first and second values. The first phase is relative to a second phase of the reference signal received by the first element.

Abstract: The disclosed technology is generally directed to downlink prioritization of on-orbit spaceborne data. In one example of the technology, image metadata and raw image data obtained from sensors on the constrained-environment device are stored. The raw image data includes a plurality of images. A plurality of images tiles is provided such that the plurality of images tiles includes, for each image of the plurality of images, evenly-spaced portions of the image. Via an embedding-generation model, a plurality of embeddings is generated based on the plurality of image tiles. The plurality of embeddings is used to perform a prioritization of image tiles among the plurality of image tiles. During a downlink session from the constrained-environment device, image tiles from among the plurality of image tiles are downlinked based, at least in part, on the prioritization.

Abstract: An inverse stirrup for use in horseback riding that a horseback rider contacts with the top of the rider's foot to resist upward or transverse force and maintain position on the horse. The inverse stirrup is attached to the horse by means of a circumferential or semi-circumferential strap such as the girth strap passing beneath the horse such that the inverse stirrup resists displacement upward.

Abstract: A catheter for use in analyzing neural activity of nerves that surround a biological lumen includes a handle and a shaft extending from the handle. The shaft configured to be inserted into the biological lumen. The selectively inflatable balloon is located on the shaft. The distal electrode and the proximal electrode are longitudinally spaced apart from one another on the shaft. Each of the distal electrode and the proximal electrode is configured to be selectively transitioned between a non-intussuscepted position and an intussuscepted position.

Abstract: A device for elevating the legs and feet of a supine patient is formed by a unitary body having a top surface and a bottom surface, a front edge, a rear edge and two opposing side edges. Two open channels extending from the front edge to the rear edge are formed in the top surface and are configured to accommodate the lower legs or feet of the patient. The channels are separated by a divider. The channels are sloped upward from rear to front, so that the feet are elevated the most. In use, the patient places both of their lower legs into the channels, with the feet extending beyond the front edge of the device. The elevation of the device prevents the feet from touching the supporting surface.

Abstract: Described herein are catheters for use in analyzing neural activity of nerves that surround a biological lumen. Such a catheter comprises a handle including a first, second, and third actuators, and a shaft extending from the handle and including proximal and distal electrodes that are selectively deployable. The first actuator is configured to selectively deploy the proximal electrode in response to the first actuator being manually maneuvered. The second actuator is configured to selectively deploy the distal electrode in response to the second actuator being manually maneuvered. The third actuator is configured to selectively adjust a longitudinal distance between the proximal and distal electrodes in response to the third actuator being manually maneuvered.

Abstract: A computing system may include a computing device, within a computational instance that is associated with a managed network, and a proxy server application disposed within the managed network, where the computing device is configured to: obtain a first reference to an element of a de-serialized state representation of a workflow; determine that the element contains a text string greater than a pre-determined threshold length; write a first compound object to a file, where the first compound object contains the text string and a key that uniquely identifies the text string; associate the key with the text string in a map; obtain a second reference to the element; determine that the text string contained by the element is associated with the key in the map; and write a second compound object to the file, where the second compound object contains the key but does not contain the text string.

Abstract: A detection method is presented that combines two non-linear approaches, the Sphere Decoder (SD) and the K-best algorithms, to identify symbols transmitted over a communication channel in a multiple input-multiple output (MIMO) communication system. A parallel implementation on a x86 computer system is presented, which reduces the number of evaluations by branching over plural symbols and diversifies the search process, which may rapidly reduce the radius and thus, the time complexity of the computer system.

Abstract: Personal Protective Equipment (PPE) is treated with a solution containing a quaternary ammonium compound bonded to a silane. The solution imparts antimicrobial and antiviral qualities to the PPE. The method includes soaking the PPE in the solution and drying the PPE, which imparts a long-lasting coating of the compound to the PPE. The treatment is useful for treating face masks, gloves, gowns, face shields, head coverings, foot coverings, and any other objects that require antiviral treatment.

Abstract: A method and apparatus which enables a facility or entity such as ships, airplanes, and land based sites, that transmits and receives radar signals to receive any incoming radar signal, while blocking reception of any signals generated by the facility or entity itself. The method comprises transmitting a primary signal from an rf generator; providing a second signal which is synchronized with the primary signal matching in both phase and amplitude, but with a phase difference of 180 degrees so that the two signals sum to zero. The second signal travels through a voltage controlled attenuator and thru a voltage controlled phase shifter. Combining in a combiner the second signal with a signal radiated by a transmitting antenna and received by a receiving antenna that connects into a transmission enabling mechanism, and then transmitting the combined signal to a detector apparatus.

Abstract: A data processing system assigns stored documents within a distributed storage system (DSS) to various document categories to enable a target number of documents to be deleted. An intelligent storage management (ISM) utility identifies a data storage threshold value used to control data storage within the DSS. If a current storage usage exceeds the data storage threshold value, the ISM utility calculates, based on the current storage usage, a target number of documents that can be deleted from the DSS. The ISM utility utilizes a recursive process, which includes assigning stored documents to groups including a set of document categories based on data characteristics of the stored documents. The ISM utility further utilizes the recursive process to delete, based on an established ordering of the groups, all of the stored documents assigned to a subset of the groups in order to remove the target number of stored documents.
