Abstract: One or more embodiments described herein disclose methods and systems that are directed at providing enhanced privacy, efficiency, convenience and security to distributed ledger-based networks (DLNs) via the implementation of zero-knowledge proofs (ZKPs) in the DLNs. ZKPs allow participants of DLNs to make statements on the DLNs about some private information and to prove the truth of the information without having to necessarily reveal the private information publicly. As such, the disclosed methods and systems directed at the ZKP-enabled DLNs provide privacy, ease and efficiency to participants of the DLNs while still allowing the DLNs to remain as consensus-based networks.

Abstract: A processor-implemented method for the ownership transfer and tracking of tangible assets using a blockchain is described. In an embodiment, the method includes generating a root node associated with a tangible asset via a processor. The root node has a first hash value that represents a storage location of the root node, data associated with a tangible asset, and a second hash value that represents a storage location of the subsidiary node. The method also includes storing a hierarchical hash-linked tree structure in a non-transitory, processor-readable memory. The hierarchical hash-linked tree structure can include multiple nodes. The multiple nodes include the root node and the subsidiary node. The subsidiary node has the second hash value, and data associated with a tangible sub-asset of the tangible asset.

Abstract: One or more embodiments described herein disclose methods and systems that are directed at facilitating access to and retrieval of data concealed on a distributed ledger-based network (DLN) with the use of zero-knowledge proof (ZKP) techniques. The methods and systems allow for the encryption, using an encryption key, of data related to a transaction between participants of the DLN, the encryption of the encryption key using a public key of an auditor of the transaction, and the generation of a ZKP that the encryption key used to encrypt the data corresponds to the encryption key encrypted using the public key such that the encrypted encryption key and/or the encrypted data are available to the auditor after the ZKP is verified by a self-executing code segment of the DLN. The ZKP also includes a proof that the encrypted data includes the transaction data.

Abstract: In an embodiment, a method comprises receiving a request that is configured to cause a transfer of a combined asset from a sender to a recipient, the combined asset including a first asset and a second asset. The method includes generating and sending to a self-executing code segment on a distributed ledger-based network (DLN) a zero-knowledge proof (ZKP) that a plurality of leaf nodes of a hierarchical tree structure representing the combined asset includes the plurality of leaf nodes of the hierarchical tree structure representing the first asset and the plurality of leaf nodes of the hierarchical tree structure representing the second asset. The method also includes receiving, in response to verification of the ZKP by the self-executing code segment, a confirmation confirming a representation of the combined asset on the DLN by a third token associated with the root node of the third hierarchical tree structure.

Abstract: The invention is a therapeutic sports towel that integrates the features of a sports towel and a stretching device into a single device that incorporates the desired properties of the two. The therapeutic sports towel is thus absorbent and convenient to carry on a golf bag or drape over a shoulder, while also having the appropriate resistance and recoil properties for therapeutic stretching. Further, the combination of a towel material with a stretchable material ensures that the therapeutic stretching has a predetermined maximum length, to prevent the overstretching that is commonly associated with therapeutic stretching bands and so forth. Various embodiments of the invention include one or more pockets for holding ice or ice packs, such that the ice or ice packs may be retained in place against sore or pulled muscles by tying or fastening the therapeutic towel appropriately around the body or a body appendage.

Abstract: The invention provides heat stable aqueous solutions or gels comprising a biologically active protein and a stabilizing effective amount of a mixture of a polysaccharide and an amino acid based compound. The invention also discloses stabilized solutions or gels suitable for use in an implantable drug delivery device at body temperature, and a device containing the stabilized solution or gels.

Abstract: An EMG monitoring system includes a matrix of detection electrode arrays that is positioned on the patient along his or her spine. The arrays are electrically connected through a switching mechanism to EMG amplifiers that are included in conventional monitoring instrumentation. A switch controller operates the switches to provide signals to the EMG amplifiers from selected sets of detection electrode arrays. The controller controls the switches to provide signals simultaneously to each EMG amplifier. If the monitoring instrumentation includes four EMG amplifiers, the matrix of electrode arrays and the switching mechanism may be used to take simultaneous measurements at two different spinal levels. If additional EMG amplifiers are included, simultaneous measurements at additional spinal levels may also be made. The matrix may also include redundant arrays and/or electrodes, such that the clinician can select the sets of electrodes that conform to the size of the patient.

Abstract: A cellular radio system includes three neighboring cells A3, A2, A1 which each have a number of channels (1 to 13, 14 to 26, 27-39 respectively) allocated for their use. A microcell M contained within cell A1 is served by a separate base station. The microcell has available to it channels 1 to 6 and 21 to 26 from the allocations of neighboring cells A2 and A3. The base stations A2, A3 and M are controlled such that no channel is in use simultaneously in both the microcell M and cell A2 or A3. This arrangement allows channels to be reallocated between neighboring cells according to demand, without reducing the peak capacity in individual cells.

Abstract: A cellular telecommunications network includes spaced apart base stations. Each base station has three directional antennas for transmission and reception of signals to subscriber units. Eight frequency groups are assigned among all the antennas such that each frequency group is reused on average at three out of every eight base stations.
