Abstract: The systems and methods described herein relate to providing verification of user identities within a review engine via authentication non-fungible tokens (“aNFTs”). The system receives an identity verification for a user of a review engine, then assigns a unique pseudonymous identity to the user. The system receives an identity verification for a provider on the review engine. The system then generates an aNFT that is unique to the provider. The aNFT includes one or more value attributes which correspond to at least authenticating the user within the review engine. Next, the system generates a review-in-progress to be displayed on the user client device. The system then receives a completed review from the user client device, and records hashed data associated with the completed review into a transaction record on a public blockchain network, such that the transaction record can be publicly audited on the public blockchain network.

Abstract: The systems and methods described herein relate to providing review content which is verifiable in a public blockchain network. The system receives an identity verification for a user of a review engine, then assigns a unique pseudonymous identity to the user based on the identity verification. Next, the system receives an identity verification for a provider on the review engine, and generates an authentication token unique to the provider to be displayed on a user client device associated with the user of the review engine. In response to the user capturing the authentication token via the client device, the system generates a review-in-progress to be displayed on the client device. Upon receiving a completed review from the user, the system records hashed data associated with the review into a transaction record on a public blockchain network, such that the transaction record can be publicly audited on the public blockchain network.

Abstract: A modular exciter beam fitted to a vibratory screen assembly. The exciter beam spans between opposing side walls of the screen assembly. The modular exciter beam provides mounting for a pair of exciter mechanisms which are located substantially inside the side walls of the screen assembly.

Abstract: An ore screening deck frame system which consists of a machine frame having a machine attachment portion and a support rail attachment portion and a panel support rail having a frame attachment portion and a panel attachment portion where in the rail attachment portion of the frame and the frame attachment portion of the rail are in end view cross section of a complementary shape so that the frame and rail can be locked together. The frame member comprises a vertically disposed web adapted to be secured to the screening machine and a frame support extending laterally of the upper edge of said web wherein the web and support are formed from reinforced wear resistant elastomeric material and the support consists of a central channel section in which the width of the channel opening is narrower than the internal width of the channel and the external lateral edges of the frame support include protrusions adapted to retain screen panel support rails.

Abstract: A compression algorithm for the compression of ECG recordings uses the Karhunen-Loeve Transform (KLT) to transform a set of N sampled ECG beats from a matrix of N.times.M samples into a new form, from which a selected subset can be retained for storage, transmission, or analysis. In order to reduce computation time and storage space, a multirate downsampling operation may be applied, which retains the appropriate spectral information in each block. The downsampled beats are then padded to make them of uniform size, and a Karhunen-Loeve Transform is applied to the sample set. Coefficients from the Karhunen-Loeve Transform of the sample set are retained for reconstruction according to one of two criteria. The average variance of the reconstructed sample set may be controlled, or different numbers of coefficients may be retained for each beat. The KLT compressed data may be reconstituted by reverse KLT transforming the data.
