Publication number: 20230262796Abstract: Disclosed are methods and corresponding systems and devices for controlling which communication interface is used for communication in a wireless body area network of medical devices. In some aspects, a security level for data to be transmitted from a first device to a second device is determined. The first device includes a first communication interface and a second communication interface. Signals communicated over the second communication interface (e.g., a near-field communication interface) have a shorter range compared to the first communication interface (e.g., a far-field communication interface). The data is transmitted using the second communication interface based on determining that the security level for the data is higher than that associated with the first communication interface. In some instances, transmission of the data involves switching to the second communication interface after establishing an initial communication channel using the first communication interface.Type: ApplicationFiled: April 19, 2023Publication date: August 17, 2023Inventors: Anthony C.

Patent number: 11672036Abstract: A method and system are provided for controlling which communication interface is used for communication between devices that are configurable to be part of a wireless body area network (BAN) for a medical device system depending on their respective locations with respect to a first device. Based on a security secret shared between the first device and a second device, a secure communication channel can be established between the first device and the second device when the second device is located in a coverage region of the wireless body area network. A controller can determine, whether a quality of service (QoS) over the secure communication channel is greater than or equal to a first threshold. In response to the controller determining that the QoS is greater than or equal to the first threshold, data can be communicated from the first device via magnetic signals using a first BAN communication interface.Type: GrantFiled: January 25, 2021Date of Patent: June 6, 2023Assignee: MEDTRONIC MINIMED, INC.Inventors: Anthony C.

Patent number: 10034976Abstract: A fluid infusion device and related operating methods are disclosed. The fluid infusion device has a housing, a fluid pump mechanism having an inlet and an outlet, a first flow path in fluid communication with the inlet and at least partially defined by structure compatible with fluid cartridge modules containing medication fluid, a second flow path in fluid communication with the outlet and terminating at a subcutaneous conduit for a body, and a drive motor that actuates the pump mechanism. An exemplary operating method detects a first installation of a fluid cartridge module in the housing. The detecting occurs after the housing has been affixed to the body and after the subcutaneous conduit has been inserted into the body. In response to the detecting, the operating method initiates an automatic priming operation to prepare the device for delivery of the medication fluid to the body.Type: GrantFiled: March 18, 2015Date of Patent: July 31, 2018Assignee: Medtronic MiniMed, Inc.Inventors: Pablo Vazquez, Hubert K.

Patent number: 9879668Abstract: A fluid infusion device includes a fluid pump mechanism having a rotor and a stator. The rotor includes an optically detectable feature, a reference surface, and a cam element rising from the reference surface. The stator includes a cam element having a stator cam surface. The cam elements cooperate to axially displace the rotor as a function of angular position of the rotor, wherein the detectable feature rotates and axially translates as a function of angular position of the rotor. A biasing element provides force to urge the rotor cam element toward the stator cam element and toward the reference surface. A drive motor actuates the rotor to pump medication fluid from a fluid cartridge module to a body, via a subcutaneous conduit. An optical detection circuit interrogates the detectable feature during operation of the fluid pump mechanism to determine an operating condition of the fluid pump mechanism.Type: GrantFiled: June 22, 2015Date of Patent: January 30, 2018Assignee: Medtronic MiniMed, Inc.Inventors: Matthew William Yavorsky, Pablo Vazquez, Anthony C.

Publication number: 20170124930Abstract: The disclosed subject matter relates to diagnostic procedures and related device architectures that check the operating health of a display element of a host electronic device. In certain embodiments, a method of checking the health of the display element begins by entering a diagnostic health check mode for the host electronic device. The display element is controlled to display a test image while operating in the diagnostic health check mode. The operating current of the display element is measured in association with the display of the test image. The measured operating current is compared against acceptance criteria for the test image, and an alerting action is initiated when the measured operating current does not satisfy the acceptance criteria.Type: ApplicationFiled: November 3, 2015Publication date: May 4, 2017Inventors: Michael R.

Publication number: 20090284264Abstract: An inductance-based cable length-to-fault measurement device and method are described. The cable under test having a per-unit-length inductance is coupled to an inductance-sensitive oscillator, and the frequency of oscillations is evaluated using the following serially coupled modules: a comparator for digitizing the oscillator output, a pre-scaler for oscillation frequency down-conversion, and a microprocessor for counting pulses from the pre-scaler. To remove environmental and manufacturing tolerance dependencies, as well as a battery voltage dependence, the measured frequency of oscillations is compared to a frequency of oscillations of the oscillator having coupled thereto a reference inductor.Type: ApplicationFiled: May 13, 2009Publication date: November 19, 2009Applicant: Acterna LLCInventor: Anthony C.
