  • Patent number: 11906480
    Abstract: Shaped charges used in wellbore perforating operations may be tested using a stressed rock perforating-charge testing system. The system includes a shaped charge testing chamber. The shaped charge testing chamber may include a loading and ejection piston and a core sample chamber. The core sample chamber is in mechanical communication with the loading and ejection piston and is sized to receive a core sample. The shaped charge testing chamber also includes a core sample stress applicator to apply stress to the core sample. Further, the system includes an ejection mechanism adjacent to the shaped charge testing chamber to provide an ejecting force on the loading and ejection piston.

  • Publication number: 20240033541
    Abstract: Methods and systems confirm the treatment focus location of ultrasound energy to be delivered to a patient from a plurality of transducers. The location of focus of treatment ultrasound may be confirmed prior to the start of ultrasound therapy. In some embodiments, ultrasound therapy may comprise delivering treatment ultrasound energy from the treatment ultrasound transducers through the skull to the brain of a patient. Methods for confirming the treatment ultrasound focus location comprise determining receive focus profiles ?x,vi for particular candidate three-dimensional (3D) treatment focus locations and particular assumed ultrasound propagation velocity profiles; performing a pre-treatment (e.g. low-power) ultrasound transmission into the brain of the patient; receiving return signals; and determining the location of treatment focus based at least in part on the received return signals and the receive focus profiles ?x,vi.

  • Patent number: 11878219
    Abstract: A vertical jump system is described herein. The system includes a first member and a second member each having a member base that sits under a flooring, a flexible cord that extends between the first member and the second member at a desired height, fixtures coupled to the flexible cord along the first member and the second member. The flexible cord remains at the desired height when contacted. The fixtures are slidable along the first member and the second member and adjust the height of the flexible cord. This configuration allows a user to easily adjust the height of the vertical jump for training, athletics, and competition, without the cord or system components dislodging and causing injury to the user.

  • Publication number: 20240003759
    Abstract: The invention comprises systems and methods for evaluating changes in the operational efficiency of an HVAC system over time. The climate control system obtains temperature measurements from at least a first location conditioned by the climate system, and status of said HVAC system. One or more processors receives measurements of outside temperatures from at least one source other than said HVAC system and compares said temperature measurements from said first location with expected temperature measurements. The expected temperature measurements are based at least in part upon past temperature measurements.

  • Publication number: 20230300029
    Abstract: A method is described that determines that a replacement node device has been connected to a mesh network, the replacement node device corresponding to an original node that has been removed from the mesh network. In response to determining that the replacement node device has been connected to the mesh network, network topology data is accessed that specifies one or more data routing configurations that are each associated with a node device included in the mesh network. From among the one or more data routing configurations specified by the network topology data, a particular data routing configuration is identified that is associated with the original node device that has been removed from the mesh network. Data that specifies the particular data routing configuration that is associated with the original node device that has been removed from the mesh network is provided to the replacement node device.

  • Publication number: 20230277119
    Abstract: We provide a system that detects skin contact reactions to a set of allergens. During operation, the system enables a user to acquire an image of a patch area through a camera in a portable device, wherein the patch area is located on the skin of a patient, and wherein a patch containing the set of allergens was applied to the patch area for a period of time and removed before the image was acquired. Next, the system preprocesses the image so that a resulting preprocessed image of the patch area has a prespecified size and orientation. The system then performs image-processing operations on the preprocessed image to identify regions of the patch area corresponding to positive skin contact reactions. The system labels each identified region with a specific allergen that was applied to the region to produce test results, which identify specific allergens that produced positive skin contact reactions.

  • Publication number: 20230277750
    Abstract: A suction and irrigation implement includes a handpiece, a pair of aligned adjacent valve assemblies, a rocker and a hub. The body may be transparent to allow visualization of aspirated substances. The valve assemblies include a plunger with a conical core that increases the area of the valve opening with increased depression. The rocker, a pivoting actuator, opens one valve assembly at a time, thereby preventing simultaneous irrigation and suction. A suction and irrigation tube connects to the hub, which may be rotated to adjust the orientation of the tube, while the implement is in use. Detents define specific orientations.
