Abstract: A glide and leap system for fishing lure includes a floating lure, a channel, a first weight, and a compression spring. The floating lure includes a head section and a tail section as the head section and the tail section are oppositely positioned of each other about a transverse plane of the floating lure. The channel is internally integrated into the head section and concentrically positioned along a sagittal plane of the floating lure. The channel is angularly oriented from a frontal plane of the floating lure to the transverse plane at an acute angle. The compression spring is positioned within the channel and positioned adjacent to the transverse plane. The first weight is adjacently positioned to the compression spring and the frontal plane as the first weight is slidably positioned within the channel.

Abstract: A straightedge with a holder for a writing implement includes a planar measuring surface, such as a ruler, set square or the like, with a slide track. The slide track extends along an edge of the planar measuring surface. A first end of a writing implement holder is slidably mounted within the slide track, and a second end of the writing implement holder is adapted for releasably holding a writing implement, such as a pen, pencil or the like. The writing implement holder is movable along the slide track such that the writing implement moves along the edge of the planar measuring surface. A support made from cork, rubber or the like may be located on a rear surface of the planar measuring surface.

Abstract: Systems and methods include a computer-implemented method for predicting locations of aquifers. Missing measurements in groundwater chemistry data from aquifers are replaced with calculated equivalents. The groundwater chemistry data is split into a model building/optimizing dataset and a model validation dataset. The groundwater chemistry data is normalized. A dimensionality reduction is performed on the groundwater chemistry data, including identifying principal components. An aquifer prediction model is generated and trained using the model building/optimizing dataset and machine learning. Performance of the aquifer prediction model is validated using the model validation dataset. Locations of aquifers are predicted during production of a new well using the aquifer prediction model and groundwater chemistry data for the new well. Settings, targets, and parameters of equipment used for drilling are changed based on the predicted locations of aquafers and the groundwater chemistry of the aquifers.

Abstract: Systems and methods are provided to implement a key overloaded database table that stores multiple instances of a data item using different key attributes to facilitate different types of queries. In embodiments, different partition or sorting keys are specified in different table facets schemas, for the table or for individual items. In embodiments, when an item is inserted into the table, the insertion operation copies values from appropriate attributes of the item into overloaded partition key and sort key fields of the instances to be inserted. In embodiments, when a primary instance of an item is updated, the secondary instances are found using facet schemas stored with the primary instance and overwritten in asynchronous fashion to reflect the state of the primary instance. Advantageously, the disclosed key overloading technique reduces the need for separate index objects for the table and simplifies query planning for the table.

Abstract: A connector for a flexible fishing lure with an interchangeable swimbait is an apparatus used as a fastener for a modular fishing lure. The apparatus includes a lure body, a lure tail, a male connector, and a female connector. The lure body and the lure tail mirror the body and the tail of a live bait. The lure tail is made of soft-plastic material. The lure body is removably connected with the lure body with the male connector and the female connector. The male connector is integrated with the lure tail and the female connector is integrated with the lure body. Moreover, the lure tail is molded around a stabilizing frame and at least one panel of the male connector. The male connector latches with the female connector and is easily separated so that the lure tail may be interchanged.

Abstract: A method for providing a treasure hunt in augmented reality includes presenting an indication of a starting point of a path through an environment that, when followed, allows a virtual gift card to be obtained. Then, as a mobile computer system travels through the environment from a location proximate the starting point, navigation indications to allow the path to be followed are presented. Presenting the navigation indications may include capturing images of portions of the environment, detecting locations corresponding to the path, modifying a captured image based on a detected location by compositing it with a navigation indication corresponding to a direction of the path; and displaying the modified captured image. That the mobile computer system has been moved to a location proximate an ending point of the path can be detected and may trigger an update to an account to associate the virtual gift card therewith.

Abstract: Systems and methods are provided to implement a database system configured to return the state of a data item upon failure of a condition check on the data item during a conditional write. In embodiments, a write request may specify an indicator to return the item state upon condition failure. The request may specify multiple database operations to execute as a transaction, where failure of a single condition check will cause the entire transaction to fail and an item state causing the failure to be returned. The returned state of the data item may include a selection of the item's attributes specified by the request. Advantageously, these features allow a client to easily obtain the precise cause of a write's failure. Moreover, because the item state is returned only when a conditional write fails and only when requested, the response size of most write requests remains unchanged.

Abstract: A security testing platform can provide security teams with an extensible, cost-effective and flexible platform which can continuously test, evaluate and tune deployed security tools & policies. The security testing platform allows users to automatically simulate security threat attacks in order to measure the effectiveness of a security stack's prevention, detection and mitigation capabilities. A set of endpoints within the controlled environment may be configured to simulate the environment of the application being tested, which may be configured across multiple endpoints. Additional endpoints may also be configured as ‘attackers’ to orchestrate security attacks on the simulated environment. The security testing platform 100 may also integrate monitoring tools to gain automated insights into the detection, reliability and performance capabilities of the current security policies, rules and configurations.

Abstract: A method and apparatus for memory built-in self-test (MBIST) may be configured to load a testing program from an MBIST controller, execute the testing program, and determine and write pass/fail results to a read-out register. For example, in various embodiments, the testing program may comprise one or more write operations that are configured to change data stored in a plurality of memory bitcells from a first value to a second value while a byte enable signal is asserted in order to test stability associated with a memory bitcell, create DC and AC noise due to byte enable mode stress, check at-speed byte enable mode timing, and execute a self-checking algorithm that may be designed to verify whether data is received at a data input (Din) pin. Any memory bitcells storing a value different from an expected value after performing the write operation(s) may be identified as having failed the MBIST.

Abstract: In an example, a method of memory repair may include receiving, by a memory repair unit, a plurality of memory identifiers. The method may include determining, by the memory repair unit, that a first memory identifier of the plurality of memory identifiers corresponds to a first memory of a plurality of memories. The method may include determining, by the memory repair unit, that a second memory identifier corresponds to a second memory of the plurality of memories. The method may include outputting, by the memory repair unit, in parallel: a first value to a repair enable input of the first memory, and a second value to a repair enable input of the second memory.
