  • Patent number: 10664402
    Abstract: Example implementations relate to read operation redirect. For example, a system according in the present disclosure may include a data storage device accessible by a host. The system may include an input/output filter of an operating system of the host. The input/output filter may monitor read operations and write operations from the host to the data storage device. The input/output filter may copy a portion of the data storage device to a random-access memory (RAM) buffer within the host responsive to monitored read operations to the portion exceeding a threshold. The input/output filter may redirect a successive read operation, addressed to the portion of the data storage device, to the copy of the portion in the RAM buffer.

  • Patent number: 10654268
    Abstract: In some examples, a controller receives impedance sensor values from an impedance sensor in a printhead, determines whether the impedance sensor values correlate to a production of an effective drive bubble for the printhead, and issues a command to modify a firing parameter for a fluid ejector of the printhead based on the impedance sensor values.

  • Patent number: 10656337
    Abstract: An example system for multi-wavelength optical signal splitting is disclosed. The example disclosed herein comprises a first splitter, a second splitter, and a modulator. The system receives a multi-wavelength optical signal and an electrical signal, wherein the multi-wavelength optical signal comprises a plurality of optical wavelengths and has a power level. The first splitter is to split the plurality of optical wavelengths into a plurality of optical wavelength groups. The second splitter is to split the multi-wavelength optical signal or the plurality of optical wavelength groups into a plurality of lower power signal groups. The modulator is to encode the electrical signal into the plurality of optical wavelength groups, the plurality of lower power signal groups, or a combination thereof.

  • Patent number: 10655994
    Abstract: An apparatus includes a microfluidic channel and a flow sensor along the microfluidic channel. The flow sensor includes a heat emitting resistor for connection to an electric current source, analytical parameter sensor and electronics. The heat emitting resistor has a resistance that varies in response to temperature. The electrical parameter sensor is to sense an electrical parameter of the heat emitting resistor that is based on the resistance of the heat emitting resistor. The electronics determine a flow based on the sensed electrical parameter.

  • Patent number: 10657286
    Abstract: A computerized method involves obfuscating one or more segments of data that is part of a flow prior to analysis of the flow for malware. Each of the one or more obfuscated data corresponds to one or more anonymized data. Thereafter, an identifier is generated for each of the one or more anonymized data, and each identifier is substituted for its corresponding anonymized data. The anonymized data and its corresponding identifiers are separately maintained from the stored flow.
