  • Publication number: 20240029547
    Abstract: A method includes accessing a first dataset including aerial imagery data and infrared data, accessing a second dataset including property boundary data, and identifying property boundaries associated with a geographic area. A plurality of models is applied to the datasets to identify and compute information of interest. Based on the first dataset and constrained by the property boundaries, a building detection model can be applied to identify a building, and a vegetation detection model can be applied to identify one or more areas of vegetation. An estimated distance can be determined between each of the areas of vegetation and the building as separation data, which can be compared to a defensible space guideline to determine a defensible space adherence score. A wildfire risk map can be generated, including the defensible space adherence score associated with the geographic area.

  • Patent number: 11853578
    Abstract: Methods, systems, and devices for performing data migration operations using a memory system are described. The memory system may include a component, such as a controller, for facilitating a transfer of data between a first memory device that may implement a first memory technology (e.g., having a relatively fast access speed) and a second memory device that may implement a second memory technology (e.g., having a relatively large capacity). The component may receive an indication of the data migration operation from a host device and may initiate a transfer of data between the first and second memory devices. The controller may include one or more buffers to store data being transferred between the first and second memory devices. In some cases, the transfer of data between the first and second memory devices may occur within the memory system and without being transferred through the host device.

  • Publication number: 20230393770
    Abstract: Systems, methods, and apparatus for memory device security and row hammer mitigation are described. A control mechanism may be implemented in a front-end and/or a back-end of a memory sub-system to refresh rows of the memory. A row activation command having a row address at control circuitry of a memory sub-system and incrementing a first count of a row counter corresponding to the row address stored in a content addressable memory (CAM) of the memory sub-system may be received. Control circuitry may determine whether the first count is greater than a row hammer threshold (RHT) minus a second count of a CAM decrease counter (CDC); the second count may be incremented each time the CAM is full. A refresh command to the row address may be issued when a determination is made that the first count is greater than the RHT minus the second count.

  • Publication number: 20230380877
    Abstract: A device used in conjunction with fixation hardware to provide a two-stage process to address the competing needs of immobilization and re-establishment of normal stress-strain trajectories in grafted bone. A method of determining a patient-specific stress/strain pattern that utilizes a model based on 3D CT data of the relevant structures and cross-sectional data of the three major chewing muscles. The forces on each of the chewing muscles are determined based on the model using predetermined bite forces such that a stiffness of cortical bone in the patient's mandible is determined. Based on the stiffness data, suitable implantation hardware can be designed for the patient by adjusting external topological and internal porous geometries that reduce the stiffness of biocompatible metals to thereby restore normal bite forces of the patient. A method of 3D printing nitinol to create a patient-specific device to facilitate the establishment of a normal stress-strain trajectory in grafted bone.

  • Publication number: 20230382405
    Abstract: An apparatus for grade severity detection in a motorized vehicle includes a first sensor and a second sensor that provides data to a controller. The first sensor is configured to generate motion data indicative of at least one wheel of the motorized vehicle. The second sensor generate data, which is indicative of torque for at least one wheel of the motorized vehicle. The controller is configured to calculate a pitch of the motorized vehicle based on the torque data and one or more acceleration values derived from the position data and configured to perform a comparison of the calculated pitch to a pitch threshold. A grade severity message is generated based on the comparison.
