  • Publication number: 20240122534
    Abstract: Methods, apparatuses, systems, and implementations for inductive heating of a foreign metallic implant are disclosed. A foreign metallic implant may be heated via AMF pulses to ensure that the surface of the foreign metallic implant heats in a uniform manner. As the surface temperature of the foreign metallic implant rises, acoustic signatures may be detected by acoustic sensors that may indicate that tissue may be heating to an undesirable level approaching a boiling point. Once these acoustic signatures are detected, the AMF pulses may be shut off for a time period to allow the surface temperature of the implant to cool before applying additional AMF pulses. In this manner, the surface temperature of a foreign metallic implant may be uniformly heated to a temperature adequate to treat bacterial biofilm buildup on the surface of the foreign metallic implant without damaging surrounding tissue.

  • Publication number: 20200111107
    Abstract: An unauthorized-product detection system may compare data representing various authentication markers of items presumed to have been produced or sourced by a particular entity with stored data representing valid authentication markers of items produced or sourced by the particular entity. The authentication markers may represent inherent physical characteristics of the items or their packaging, or may be generated and applied to the items or their packaging to facilitate counterfeit detection and/or for other purposes. The data (some of which may be encrypted) may be captured using high-resolution cameras, scanners, or other devices, and then communicated to the unauthorized-product detection system for analysis. The system may maintain a data store of data representing captured or valid authentication markers and may store tracking information reflecting the use of various authentication markers.

  • Patent number: 10395243
    Abstract: Financial transactions, such as buying and selling, may be facilitated by merchant-based shadow account numbers. A master account may contain several associated shadow accounts. Each shadow account may in turn be associated with a specific merchant or group of merchants. Merchants and users may store and use the shadow account numbers rather than the master account numbers. Stolen or otherwise compromised shadow account numbers are useless with other non-associated merchants. Furthermore, the shadow numbers may be easily invalidated while leaving the master account untouched.

  • Patent number: 10271889
    Abstract: An apparatus for cooling certain tissues in the vicinity of diseased or other tissue undergoing thermal treatment is disclosed. The present apparatus is configured and designed to have certain physical characteristics, e.g., certain acoustic and imaging responses. In some embodiments the present apparatus is compatible with magnetic resonance imaging (MRI) environments used in conjunction with the thermal treatment, or other imaging environments. In some embodiments the present apparatus is detectable by said MRI and is within the imaging field of view (FOV) but causes few or no imaging artifacts. Additionally, the present apparatus does not substantially interfere with the thermal treatment, e.g., ultrasonic therapy, which can proceed to heat the targeted volume of tissue while protective cooling of tissues near the diseased tissue by the present apparatus takes place.

  • Patent number: 9707413
    Abstract: An apparatus is disclosed for thermal therapy in a male prostate patient. The apparatus includes, in preferred embodiments, a long tubular element that is to be inserted into a patient's urethra so that a first tip end of it reaches up into the patient's diseased prostate. The elongated portion includes a narrow cylindrical tube within which an ultrasonic array is disposed along the long axis of the cylinder. Fluid is pumped into and out of a treatment zone of said patient as needed to control a temperature of a region in said treatment zone. A motorized driver is used to controllably rotate said elongated portion and the ultrasound array therein about the long axis of the apparatus so as to deliver acoustic energy to said diseased tissue. Various control and monitoring components may be used in conjunction with the present apparatus to design, control, and terminate the therapy.

  • Patent number: 9101752
    Abstract: A focused ultrasound system includes an ultrasound transducer configured to emit focused ultrasound energy toward a subject and a positioning system configured to position the ultrasound transducer to localize the focused ultrasound energy within a target location. The positioning system includes a drive apparatus to translate the ultrasound transducer along at least one axis of motion and a motor controller to control the drive apparatus. The focused ultrasound system also includes a control system connected to the motor controller that is programmed to receive imaging/location data from an imaging system, determine positional coordinates of the target location based on the imaging/location data, and register the positional coordinates of the target location with the positioning system. The positional coordinates are sent to the motor controller via an input signal to cause the motor controller to control the drive apparatus so as to translate the ultrasound transducer.
