  • Patent number: 12071190
    Abstract: A locking mechanism can be used for securing a scooter or other vehicle. The locking mechanism can secure a wheel of the scooter in a left or right steering position. The locking mechanism can be manually actuated by the user, such as by a foot or hand of the user. Once the wheel is secured in place, the scooter may be difficult to ride without unlocking. The locking mechanism can be unlocked through a wireless connection with a remote control (e.g. a phone).

  • Patent number: 11738201
    Abstract: An external device for use with an implantable medical device includes circuitry that is configured to drive a coil to produce a static electromagnetic field to change a status of the implantable medical device. The static electromagnetic field may replace a physical magnet, which may not be commonly carried by a patient, to induce an emergency shutdown of the implantable medical device. The external device may be a charger or controller that is used to charge or communicate with the implantable medical device, and the coil may primarily be used for those charging and telemetry functions in such devices.

  • Publication number: 20230001219
    Abstract: Implantable medical devices (IMDs) are described. The IMDs are configured to wirelessly receive power from an electromagnetic field provided by an external charger. The IMDs include a conductive case and a header that is typically non-conductive, and which houses a three dimensional antenna structure configured to couple with the external magnetic field. Currents induced in the antenna structure are used to provide power to the IMD. The three dimensional antenna structure may be configured as a cage structure comprising a first loop antenna proximate and parallel to the front of the header, a second loop antenna proximate and parallel to the back of the header, and a third loop antenna proximate and parallel to the top of the header. The three dimensional antenna structure allows the IMD to effectively receive power from different directions, for example, if the orientation of the IMD is flipped or otherwise shifted within the patient's body.

  • Publication number: 20220323771
    Abstract: Implantable medical devices (IMDs) are disclosed which are capable of wirelessly receiving power from a magnetic field to power the IMD or charge its battery, but which do not use a wire-wound coil for magnetic field reception. The IMD can include a case housing control circuitry for the IMD, in which at least a portion of the case is conductive, with a case current formed in the conductive case portion in response to the magnetic field. The IMD includes power reception circuitry inside the case, and includes various examples of first and second electrical connections used to divert at least some of the case current as a power current to the power reception circuitry, thus allowing the power reception circuitry to use the power current to provide power to the IMD or to charge its battery.

  • Patent number: 10737103
    Abstract: Electrical energy is transcutaneously transmitted at a plurality of different frequencies to an implanted medical device. The magnitude of the transmitted electrical energy respectively measured at the plurality of frequencies. One of the frequencies is selected based on the measured magnitude of the electrical energy (e.g., the frequency at which the measured magnitude of the electrical energy is the greatest). A depth level at which the medical device is implanted within the patient is determined based on the selected frequency. For example, the depth level may be determined to be relatively shallow if the selected frequency is relatively high, and relatively deep if the selected frequency is relative low. A charge strength threshold at which a charge strength indicator generates a user-discernible signal can then be set based on the determined depth level.
