  • Patent number: 12585779
    Abstract: An electronic device may have a plurality of defined life cycle stages and a one-time-programmable (OTP) memory comprising a plurality of life cycle bits, wherein respective bit patterns of the life cycle bits may correspond with respective life cycle stages of the defined life cycle stages. The electronic device may also have a boot code stored in read only memory and executable by a processor to receive a request to transition from a current life cycle stage to a next life cycle stage and, in response to the received request, automatically generate a bit pattern corresponding to the next life cycle stage of the plurality of defined life cycle stages and program the bit pattern corresponding to the next life cycle stage of the plurality of defined life cycle stages in the OTP memory during a time when the OTP memory is not user-accessible.

  • Patent number: 12524579
    Abstract: A device with boot code, first mutable code stored in non-volatile memory, a first owner information stored in the non-volatile memory, and an SRAM with an SRAM physically unclonable function (SRAM PUF) region. Boot code may generate a first unique private key based on both the first owner information and a portion of the SRAM PUF region, wherein the first unique private key may not be directly accessible by the first mutable code; generate a first unique private keycode corresponding to the first unique private key; and provide the first mutable code with the first unique private keycode corresponding to the first unique private key. First mutable code may use the first unique private keycode to cause data to be signed with the first unique private key and generate a first unique mutable code private key based on at least a portion of the SRAM PUF region.

  • Patent number: 12510917
    Abstract: A portable communication device includes a main housing, and a knob coupled to the main housing. The knob is rotatable about a first axis that extends into the main housing, and the knob includes a channel that extends partially circumferentially about the first axis. The portable communication device also includes a button coupled to the main housing. The button is moveable linearly along a second axis that is parallel to the first axis, and the button includes a projection that is sized and shaped to extend into the channel. The button is movable between a first position in which the projection is within the channel, and a second position in which the projection is outside of the channel.

  • Publication number: 20250322041
    Abstract: A device with one-time-programmable (OTP) memory, boot code, volatile memory, and non-volatile memory. Boot code may use information in OTP to authenticate code of an implicit owner of the electronic device; receive a first create owner container request; create a first owner container comprising a first signed data image; store the first owner container; and use the first signed data image to authenticate first executable code associated with the first owner. Boot code may transfer ownership from the first owner to a second owner, including authenticating a signed transfer of ownership command using a key stored in the first owner container and creating a second owner container comprising a second signed data image associated with the second owner; storing the second owner container; revoking the first owner container; and using the second signed data image to authenticate second executable code associated with the second owner of the electronic device.

  • Patent number: 9414798
    Abstract: A method for bolus tracking includes acquiring one or more baseline images. One or more trigger regions are automatically established within the baseline images. A bolus is administered. The automatically established trigger regions are monitored for bolus arrival at the one or more trigger regions. Bolus arrival at a volume of interest is forecasted based on the bolus arrival at the one or more trigger regions. A diagnostic scan of the volume of interest is acquired at the forecasted time.

  • Patent number: 9020235
    Abstract: Systems and methods for supporting a diagnostic workflow from a computer system are disclosed herein. In accordance with one implementation, a set of pre-identified anatomical landmarks associated with one or more structures of interest within one or more medical images are presented to a user. In response to a user input selecting at least one or more regions of interest including one or more of the pre-identified anatomical landmarks, the user is automatically navigated to the selected region of interest. In another implementation, a second user input selecting one or more measurement tools is received. An evaluation may be automatically determined based on one or more of the set of anatomical landmarks in response to the second user input.
