  • Publication number: 20230289320
    Abstract: A state machine defines a plurality of predetermined states and a plurality of predetermined events, for decoding universal serial bus (USB) data communicated over a USB. Input terminals receive the USB data. A clock processor outputs synchronized data and a device clock. An event generator triggers respective ones of the predetermined events in response to respective combinations of the synchronized data, the device clock, control information, and the present state. One of the predetermined events includes identifying a stuffed-bit in the synchronized data, and another of the predetermined events includes stripping the identified stuffed-bit from the synchronized data and not toggling an output clock, to provide stuff-bit stripped synchronized data. A combination of the predetermined events includes decoding the stuffed-bit stripped synchronized data to provide decoded stuffed-bit stripped synchronized data.

  • Patent number: 11628219
    Abstract: This invention provides methods and systems for achieving high-specificity killing of targeted cells using Magneto-Electric Nano-Particles (MENPs) and functional or diagnostic imaging that detects changes at the cellular level. Embodiments comprise injecting into a patient's body manufactured MENPs that have a higher tendency to accumulate near or attach to targeted cells through one or more physical forces and/or biological mechanisms; and applying a magnetic field to the MENPs to generate an action that is sufficient to cause death of the targeted cells, and using an imaging apparatus to image or detect a specific property of the MENPs or changes in a property of the MENPs due to the coupling of the MENPs with their surrounding environment.
