  • Patent number: 11139043
    Abstract: Due to design variations, process variations, manufacturing variations, and other factors, memory of a certain type manufactured by one manufacturer often exhibits a unique pattern of performance characteristics relative to the patterns of the same type of performance characteristics exhibited by memory from other manufacturers. A system for identifying counterfeit memory is trained to learn the different patterns of performance characteristics for different manufacturers of memory. Thereafter, the system may analyze the performance of a given memory device to determine whether the memory device has been manufactured by a particular manufacturer. Thus, the system is capable of determining whether the memory device is counterfeit (e.g., has been manufactured by an unexpected manufacturer).

  • Patent number: 11114179
    Abstract: A system for testing memory includes logic that is configured to perform various normal memory operations (e.g., erase, read and write operations) on a memory device and to determine operational parameters associated with the memory operations. As an example, the amount of time to perform one or more memory operations may be measured, or a number of errors resulting from the memory operations may be counted or otherwise determined. One or more of the operational parameters may then be analyzed to determine whether they are in a range expected for counterfeit memory. If so, the logic determines that the memory under test is counterfeit (e.g., is recycled or counterfeit) and provides a notification about the authenticity of the memory. The logic may also estimate the age of the memory based on the operational parameters.

  • Patent number: 11106063
    Abstract: An electrically-tunable optical filter has an optical cavity that forms an absorption peak in light that is incident on the filter. The optical cavity includes a layer composed of a material with a high electro-optic coefficient so that the index of refraction of the layer changes in response to a voltage applied by a controller. By adjusting the voltage, the controller can control the index of refraction so that an absorption peak of the filter can be tuned as may be desired without having to alter the physical structure of the filter.

  • Patent number: 10982738
    Abstract: A coupling system can include an energy transfer device and a load mitigation system. The energy transfer device can include a shaft, gear, chain or piston-cylinder arrangement to transfer the energy from a power supply to an object to be moved. The load mitigation system can be used to limit or prevent the transfer of forces from the object to the drive unit as a result of external loads being applied to the object. The load mitigation system can be pre-loaded such that external loads on the object having an excessive impulsive or resonant cyclic force greater than the pre-load force on the load mitigation system are reduced and only partially transferred to the energy transfer device and power supply. The load mitigation system can dampen both resonant loads and impulsive impact loads occurring at the object thereby preventing damage and extending life.

  • Patent number: 10928550
    Abstract: A weather forecasting system has a data processing system that receives weather data from one or more sources and processes such data in conjunction with a weather forecasting algorithm in order to forecast weather for one or more geographic regions. In this regard, the weather data is input into a machine learning algorithm, which applies learned weights and relationships to the inputs in order to calculate at least one score indicating a probability that precipitation or other weather event will occur in the future within a certain time period (e.g., within the next 1 hour or some other unit of time) in one or more geographic regions. For each such geographic region, the weather forecasting logic may also predict the extent to which rain or other precipitation, lightning, or other weather event will occur during the time period.

  • Patent number: 10900822
    Abstract: The present disclosure generally pertains to devices and methods for determining propellant mass based on average measurements irrespective of the fluid orientation in a fuel tank. The device is useful in detecting fuel levels in tanks where the fuel is in motion, for instance in aircraft (i.e., undergoing varying acceleration maneuvers) or spacecraft (i.e., a microgravity environment). The devices and methods can also be used for determining the liquid in a surface tension screen liquid acquisition device (LAD), and particularly, the incipient breakdown as gas bubbles enter or are formed inside the LAD as the screen dries or heat transfer induces vaporization. The same basic electrode configuration can be used to stir the liquid to reduce thermal stratification and condense vapor bubbles.

  • Patent number: 10878922
    Abstract: A radiation detection system may include a mobile device having a flash memory. The device may monitor various characteristics of the flash memory to determine when damage to the flash memory has occurred from radiation exposure. The device may associate damage to the flash memory with a radiation dose, and determine a level of radiation to which the memory, and thus the device, has been exposed. The device also may determine a length of time and locations where the radiation exposure has occurred. If the device determines that the level of radiation exposure exceeds a threshold associated with a safe level of radiation exposure for a human user, the device may generate an alert to the user.

  • Patent number: 10812184
    Abstract: The present disclosure generally pertains to signal analysis systems and methods for measuring and characterizing signal attributes, such as noise. A signal analysis system comprises an optical receiver that receives an optical signal and converts the received signal into an electrical signal. A programmable frequency divider divides the frequency of the incoming electrical signal at different division ratios, and a signal analyzer analyzes the resulting signal. In this regard, by increasing the division ratio of the frequency divider and measuring the power spectral density with the signal analyzer at different division ratios, a suitable signal for determining different parameters (e.g., modulation frequency and modulation index) may be found.

  • Patent number: 10554683
    Abstract: Systems and methods are provided to implement moving target defense techniques for transportation systems. The moving target defense techniques can randomly change the IP addresses of the nodes associated with both the vehicles and the corresponding control centers. The nodes for the vehicles and the control centers can be “mobile” nodes that use a “care-of” IP address for communications. The care-of address used by the nodes can be updated through a binding update process. During the binding update process, the one node sends the binding update notice (with a new care-of address) to the care-of address of the other node while maintaining its prior care-of address. The node that receives the binding update notice can send a binding acknowledgement back to the node that sent the binding update. Once the binding acknowledgement is received, the prior care-of address can be removed by the node that sent the binding update.
