  • Publication number: 20220305271
    Abstract: An energy supplying component (100) includes a plurality of power sources (161, 171, 181, 191) and at least one switch (163, 165, 167, 173, 175, 177, 183, 185, 187, 193, 195, 197). Each power source of the plurality of power sources is configured to output a defined energy level. The at least one switch is configured to reversibly combine two or more power sources of the plurality of power sources for enabling the energy supplying component to supply requested energy at one or both of a needed voltage or a needed current.

  • Publication number: 20160250481
    Abstract: A magnetic field sensor includes at least one sensing circuit including giant magnetoresistive (GMR) elements. At least one of the GMR elements is at least partially housed in a flux-reducing or flux-concentrating first shielding material that reduces or amplifies, respectively, the magnetic field impinging on the element(s), while at least one other GMR element is housed in a second shielding material having an effect opposite that of the first shielding material, or is not housed in any shielding material. A measurement circuit is configured to measure voltage between different points of the GMR sensing circuit, allowing derivation of electric impedance between the different measurement points. An evaluation circuit evaluates the impedances and the relationships therebetween to derive a signal that indicates the strength of an applied magnetic field.

  • Patent number: 8428528
    Abstract: The invention relates to methods by which radio signals can be transmitted to, and received by, a radio receiver such that the receiver consumes very little power from a battery or energy source. The invention also relates to methods by which radio signals, modulated with data information, can be produced by a transmitter that consumes very little power. The invention is applicable not only to medical implants, but any application requiring a radio receiver to operate with very low power consumption.

  • Patent number: 8315708
    Abstract: A patient device (PD) for wireless data communication with an implant. The PD can be at least in an unpaired state or a paired state. In the paired state the PD is paired to a specific implant specified by an implant's identification code (IIC). The IIC is stored in PD memory. Automatic pairing of the PD to a specific implant is performed upon receiving an incoming data packet containing an IIC when the PD is in its unpaired state with no valid IIC stored in memory. Thus, the PD is tentatively paired to an implant identified by the IIC contained in the incoming data packet by storing the IIC in the memory. Tentative pairing is cancelled if no further communication occurs within a predetermined period of time. A soft paired state is entered if further data communication does occur.

  • Publication number: 20080154342
    Abstract: An implantable medical device comprises an electronic control unit and a magnetic resonance imaging magnetic field detector that is connected to the control unit. The magnetic resonance imaging magnetic field detector is adapted to generate a signal being characteristic for a magnetic field as used for magnetic resonance imaging (MRI) and the control unit is adapted to positively recognize a presence of a magnetic field as used for magnetic resonance imaging (MRI) and to cause the implantable medical device to enter an MRI-safe mode of operation.
