  • Patent number: 12254222
    Abstract: The invention is notably directed to a method of programming memory elements of an in-memory computing (IMC) device. The IMC applies a SET signal to the K memory elements of said each cell to set each of the K memory elements to a SET state and reading K conductance values of the K memory elements in the SET state. The IMC adjusts, based on the K conductance values read and the target conductance value, a conductance value of at least one of the K memory elements to match a summed conductance of the K memory elements of said each cell with the target conductance value. The IMC maximizes a number of the K memory elements that are either in their SET state or in a RESET state of zero conductance nominal value, such that at most one of the K memory elements is neither in a SET state nor in a RESET state.

  • Patent number: 12255671
    Abstract: The method provides for separable subchannels sharing a communication channel. A processor receives input of a user setting a transmitter device to a first of at least two subchannels of a communication channel in which the first subchannel comprises a first portion of a bandwidth of the communication channel. The processor receives an audio signal as input to the transmitter device. The processor converts a time-series waveform of the audio signal into a frequency-series waveform. The processor determines that the transmitter device is set to the first subchannel. In response to determining the device is set to the first channel, the processor filters the frequency-series waveform through a series of steep shoulder digital bandpass filters set to transmit through the first portion of the bandwidth, and the processor transmits the audio signal as the filtered frequency-series waveform.

  • Patent number: 12248456
    Abstract: A computer-implemented method, system and computer program product for improving accuracy and efficiency of auditing databases. A table, list or index of a database is analyzed to identify metadata, which includes time series data, user data, an Internet Protocol address and operation data. The identified metadata is associated with the corresponding record or row of the table, list or index from which the metadata was extracted. A determination is then made as to whether to record a raw data image associated with the record or row of the analyzed table, list or index based on the corresponding data operation. The identified metadata as well as the recorded data images, if any, are stored in a structured audit log. Auditing information is then obtained from a structured audit log based on matching the record or row identifier (RID) associated with the query with the RID associated with the structured audit log.

  • Patent number: 12250314
    Abstract: Mechanisms are provided for computing resource access security in which a credential of a user agent is authenticated to determine if the user agent is associated with an entity for which an attribute based encryption (ABE) key is to be generated. If so, an ABE key is generated and provided which corresponds to a set of attributes of the entity. Token issuance logic receives a token request and the ABE key from a relying party computing device and executes a decryption operation on locking metadata associated with at least one attribute value based on the ABE key. The token issuance logic, in response to the decryption operation successfully decrypting the locking metadata, issues a generated token to the relying party computing device based on the at least one attribute value. The relying party computing device accesses the computing resources using the generated token.
