Abstract: A folded slab waveguide laser having a hybrid waveguide-unstable resonator cavity. Multiple slab waveguides of thickness ‘t’ supporting vertical waveguide modes are physically arranged above one another in a stack and optically arranged in series through one or more cavity folding assemblies with curved mirrors. A gain medium such as a gas is arranged in each slab. Each cavity folding assembly is designed to redirect the radiation beam emitted from one slab waveguide into the next waveguide and also at the same time to provide a focus for the radiation beam so that a selected vertical waveguide mode (or modes) is (or are) coupled efficiently into the next slab.

Abstract: Methods and systems are provided for converting a loop (e.g., a cursor loop) to a declarative Structured Query Language (SQL) query that invokes a custom aggregate function. The loop includes a select query and a loop body that includes a program fragment that can be evaluated over a result set of the select query one row at a time. The system verifies that the loop body does not modify a persistent state of the database. A custom aggregate function that expresses the loop body is automatically constructed according to a contract. An aggregate class comprising aggregation methods of the contract are used to construct the aggregate function based on results of static analysis. The select query is automatically rewritten to form a declarative SQL query that invokes the custom aggregate function. The declarative SQL query may be executed by a database management system (DBMS) SQL server.

Abstract: Systems and methods for obfuscating and/or deleting data records are provided. In one implementation, a method for obfuscating data includes a step of receiving a request from a client to obfuscate data records associated with the client. The data records are stored in one or more databases throughout a network. The method also includes searching for one or more occurrences of the data records appearing throughout the network. Upon determining that the data records can be obfuscated without causing undesirable consequences elsewhere in the network, the method includes obfuscating the one or more occurrences of the data records.

Abstract: A secure cloud-based node-locking service with built-in attack detection to eliminate fuzzing, cloning and other attacks is disclosed.

Abstract: A tool and an associated method for removing a prosthetic implant includes a lateral tool, a first impact tool secured to the lateral tool, a medial tool, and a second impact tool. Although the tool can be used to remove a variety of different prosthetic implants, it finds particular application in the removal of femoral implants. Both lateral and medial tools are utilized. The lateral tool includes a generally arcuate shape with upstanding sidewalls that define an arcuate interior. The lateral tool is thus dimensioned to follow the contour of the lateral side of a femoral implant. The medial tool includes opposing side walls that define an interior opening. The opening is sized to receive the neck of the femoral implant, thereby allowing the tool to closely follow the medial bone/implant interface.

Abstract: A drainage catheter system comprising a catheter having an elongate body \configured for insertion into an organ or cavity of a patient and a hub configured for coupling with a longitudinal shearing device and the first end of the catheter and movable over the elongate body of the catheter. A locking stay suture extends through the elongate body of the catheter. The length of the elongate body of the catheter can be adjusted by sliding the hub coupled to the longitudinal shearing device along the longitudinal axis of the catheter, and then creating a longitudinal cut in the catheter through which the proximal end of the locking stay suture can be removed and secured, thereby enabling the excess catheter tubing to be removed by cutting and allowing the base to rest flush against the patient's body.

Abstract: Various technologies presented herein relate to a method and equipment for detecting both airborne radioisotope and molecular effluent gases. Multi-Axis Sensing can be conducted by utilizing a pressurized MOF sorbent, such as a scintillating Metal-Organic Frameworks (S-MOFs).

A method for detecting an analyte in a fluid sample is provided that comprises: loading a sorbent with a sample fluid, wherein the sorbent comprises a MOF material; pressurizing the sample fluid to increase the fluid in the sorbent thereby making a pressurized sorbent; and detecting ionizing radiation or a chemical property of the analyte in the pressurized sorbent.

Abstract: The present disclosure is directed to automatically generating a 360 Virtual Photographic Representation (“spin”) of an object using multiple images of the object. The system uses machine learning to automatically differentiate between images of the object taken from different angles. A user supplies multiple images and/or videos of an object and the system automatically analyzes and classifies the images into the proper order before incorporating the images into an interactive spin. The system automatically classifies the images using features identified in the images. The classifications are based on predetermined classifications associated with the object to facilitate proper ordering of the images in the resulting spin.

Abstract: An imaging device may include a plurality of single-photon avalanche diode (SPAD) pixels. The SPAD pixels may be overlapped by square toroidal microlenses to direct light incident on the pixels onto photosensitive regions of the pixels. The square toroidal microlenses may be formed as first and second sets of microlenses aligned with every other SPAD pixel and may allow the square toroidal microlenses to be formed without gaps between adjacent lenses. Additionally or alternatively, a central portion of each square toroidal microlenses may be filled by a fill-in microlens. Together, the square toroidal microlenses and the fill-in microlenses may form convex microlenses over each SPAD pixel. The fill-in microlenses may be formed from material having a higher index of refraction than material that forms the square toroidal microlenses.

Abstract: A method of singulating a silicon carbide (SiC) semiconductor wafer can include defining a cut within the silicon carbide (SiC) semiconductor wafer by performing a partial dicing operation where the SiC semiconductor wafer is aligned along a plane and the cut has a depth less than a first thickness of the SiC semiconductor wafer. The cut is aligned along a vertical direction orthogonal to the plane such that a portion of the SiC semiconductor wafer has a second thickness that extends between a bottom of the cut and an outer surface of the SiC semiconductor wafer. The method can further include defining a cleave, by performing a cleaving operation, through the portion of the SiC semiconductor wafer having the second thickness. The cleave can be aligned with the cut and extending to the outer surface of the SiC semiconductor wafer.

Abstract: Methods, systems, apparatuses, and computer program products are provided for reconstructing network activity. A network activity monitor is configured to monitor network activity for various network entities. Based on the monitoring, a set of features may be obtained for each network entity.

Each of the vertices may be assigned a different usage pattern that represents a certain type of network usage types. Reconstructed network activity for a particular network entity may be represented as a weighted combination of the usage patterns. Based on the reconstruction, a network anomaly may be detected, a network may be modified, and/or an alert may be generated.

Abstract: Some embodiments provide a method, for a software-defined wide area network (SD-WAN) that handles (i) traffic for a 5G network and (ii) traffic outside of the 5G network. The SD-WAN is established by a set of edge nodes and a set of gateways. At a particular edge node of the SD-WAN, the method identifies whether a received data message is a 5G message that includes a tunnel header of a particular type associated with the 5G network. When the data message is a 5G message, the method examines a set of header fields within the tunnel header to identify a specified traffic priority applicable to the 5G message. The method applies the identified traffic priority within the SD-WAN.

Using the user interaction data for the selected user interactions, a quantity of user interactions that are associated with each conversion and occurred during the conversion cycle for the conversion are determined. In turn, conversion path performance measures are computed and reports specifying the conversion path performance measures are generated.
