98 results about "Binary strings" patented technology

Binary strings. A binary string is a sequence of bytes. Unlike character strings, which usually contain text data, binary strings are used to hold non-traditional data such as pictures, voice, or mixed media. Character strings of the FOR BIT DATA subtype may be used for similar purposes. Binary strings are not associated with a code page.

System and Method for Compaction of Floating-Point Numbers Within a Dataset with Metadata Tagging

A system and method for multi-level compaction of floating-point numbers and associated metadata within datasets. The system identifies floating-point numbers and their associated metadata, pre-encodes numbers into binary string representations, and encodes metadata into compact binary form. These encoded elements are linked together and indexed to indicate they represent floating-point numbers with metadata. The dataset is organized into multiple compaction levels based on semantic relationships between metadata elements. The system creates specialized indices for metadata-based retrieval, maintains relationship maps, and implements inheritance policies across hierarchical levels. During retrieval, the system reconstructs both the original floating-point values and their associated metadata, preserving hierarchical relationships. This approach enables more intelligent data organization, richer contextual information preservation, and more powerful query capabilities while maintaining efficient floating-point compaction.

System and method for preprocessing and conditioning cosmic ray data for randomness generation

The present disclosure describes a method for conditioning and preprocessing raw cosmic ray data to extract features and generate a binary string representing the inherent randomness in the data. Measurable characteristics of cosmic ray particles, such as arrival times and amplitudes, are processed to create random binary sequences. These binary strings are then used to train a generative adversarial network (GAN) framework. In the GAN framework, the generator creates random sequences resembling the target distribution, which matches the entropy of the conditioned cosmic data. The discriminator evaluates the generated sequences by comparing them to the conditioned cosmic data and assigns a randomness score that characterizes the quality of the generated sequences. This adversarial process ensures the generation of high-quality random sequences that are statistically indistinguishable from the conditioned input data.

A low-computing-power feature extraction and data compression method for acceleration sensor data

The present invention discloses a low-computing-power feature extraction and data compression method for acceleration sensor data. The method includes a feature extraction algorithm for three-axis acceleration sensor data, and a data compression algorithm for the extracted features. After the acceleration data is segmented by a sliding window, the resultant acceleration direction is calculated. According to the pre-defined base directions, the base direction numbers are used to replace the resultant acceleration directions in sequence according to the proximity principle. The direction codes are counted to obtain a histogram of the frequency of occurrence of each base direction in a single sliding window. In a short period of time, the distribution of the resultant acceleration direction is relatively concentrated. Based on this property, the value 0 is encoded as a single bit with a value of 0. For non-zero values, 8 bits are used to represent it. The first bit is fixed to 1 as a flag bit, and the last 7 bits are the binary values ​​of the corresponding frequencies. The encoded binary string is used for data transmission. Application of this method can save the computational overhead of the feature extraction and data compression process and reduce the overall power consumption of the device.
