Abstract: A microelectronic device with a trench structure is formed by forming a trench in a substrate, forming a seed layer in the trench, the seed layer including an amorphous dielectric material; and forming semi-amorphous polysilicon on the amorphous dielectric material. The semi-amorphous polysilicon has amorphous silicon regions separated by polycrystalline silicon. Subsequent thermal processes used in fabrication of the microelectronic device may convert the semi-amorphous polysilicon in the trench to a polysilicon core. In one aspect, the seed layer may be formed on sidewalls of the trench, contacting the substrate. In another aspect, a polysilicon outer layer may be formed in the trench before forming the seed layer, and the seed layer may be formed on the polysilicon layer.

Abstract: Exemplary systems and methods are directed to embedding data into a machine learning model. A processing device executes program code for running a machine learning model, which has a plurality of parameter values. The processing device receives a message to be embedded into the machine learning model. The message is encrypted according to a set of keys of a cryptographic algorithm. The encrypted message is converted to a corresponding binary representation. The binary representation of the encrypted message is embedded into at least one of the one or more parameters of the machine learning model. The embedding operation modifies the at least one parameter value of the machine learning model.

Abstract: Exemplary systems and methods to extract, transform, and save to memory features from a training and a test dataset at extraction layers in a machine-learning model. For each data element in the training dataset, at each extraction layer: feature maps are created and grouped by k unique data labels to construct a set of k class-conditional distributions. For each data element in the datasets: distance sets between each feature map of each extraction layer and the extraction layer's class-conditional distributions are calculated and reduced to distance summary metrics. A drift test statistic for each extraction layer is computed between the datasets by comparing the extraction layer's distance summary metric distributions of the test dataset to distance summary metric distributions of the training dataset. The measure of drift between the datasets is computed by combining the test statistics of the extraction layers through a mathematical transform.

Abstract: A tie-down assembly for selective attachment to a structure at an oblong aperture defined thereby and detachment therefrom includes an anchor arranged along an axis. The anchor has an oblong-shaped section configured to be inserted into the structure's oblong aperture. The anchor also has a knob section which turns the anchor's oblong-shaped section about the axis when a torque is applied to the knob section. The assembly also includes a rail mount configured to abut the oblong-shaped section, and defining a pocket for accepting the knob section and limiting rotation of the oblong-shaped section via contact with the knob section. The anchor's oblong-shaped section and the rail mount are together configured to sandwich therebetween material of the structure proximate the oblong aperture after the anchor's oblong-shaped section is inserted into and turned relative to the oblong aperture to thereby attach the tie-down assembly to the structure.

Abstract: A method of performing geolocation of receivers, transmitters, and conductive objects includes detecting, with one or more receivers, magnetic field signals generated by one or more transmitters, with each transmitter including two or more co-located coils that are electrically unstable and unbalanced, and that have a mechanically stable orientation with respect to one another. The magnetic field signals from each of the two or more co-located coils of each of the two or more transmitters are decomposed into individual magnetic field components. A set of invariant scalar values that are independent of orientation of one or more magnetic antennas associated with the one or more receivers are calculated from the individual magnetic field components, and the position of an object is determined using the set of invariant scalar values.

Abstract: Disclosed are systems and methods for processing financial information such that securities backed by tax-exempt bonds may be issued. In one embodiment, the method includes establishing a senior class of securities, such that the senior class of securities includes a guarantee feature; establishing a junior class of securities, such that the junior class of securities serves as collateral for the senior class of securities; and issuing the senior and junior classes of securities, such that the junior and senior classes of securities are backed by assets of a single trust.

Abstract: Automatic failover methodology provides a mechanism whereby a central control unit, such as a management station, will automatically takeover interface status polling of objects of a collection station that is temporarily unreachable. This methodology is applicable to any distributed computing environment, such as a data communications network, in which it is desirable to have a central control unit assume the interface status polling operation of a temporarily inaccessible collection station. The collection station may be inaccessible due to the network on which the central control unit and the collection station reside being down or due to the collection station being down for maintenance.

Abstract: Apparatus for applying a signature or other hand written data to a file or document created, stored and/or displayed in html format, comprising input means (10) for electronically capturing hand written data and including storage means (12) for storing the data in bit map format. The apparatus further includes a module (14) which attaches a key or link into a computer programme being used to create an html document such as an e-mail and creates an option (16) for selection by the user when the hand written data (18) is required to be added to the document (20). When the option (16) is selected, the module (14) cause a routine which gets the stored data from the storage means (12) and converts the data from bit map format to html format, which is the same format as that used to create a web page or conventional e-mail. Once the text is converted to html format, it is added to the e-mail being created at a position chosen by the user.
