  • Publication number: 20240156367
    Abstract: A wirelessly powered medical implant system comprising: a power source system including: an automatic gain controller to receive input power, automatically adjust the input power based on a feedback signal with an offset phase delay, and provide the adjusted input power as output power; a source resonator to generate, based on the output power, a magnetic field to transmit wireless power via the magnetic field, and provide the feedback signal; and an offset phase delay circuit to receive the feedback signal from the source resonator, generate the offset phase delay, and include the offset phase delay with the feedback signal; and a medical implant including: an implant resonator to receive the transmitted wireless power via the magnetic field; and one or more sensors, wherein the feedback signal is based on inductive coupling of the magnetic field between the source resonator and the implant resonator.

  • Publication number: 20070120938
    Abstract: Reflex writing is a group of algorithms developed to maintain color registration in xerographic systems using multiple imagers. Unlike conventional imaging, in which the individual color separations are imaged based on events in a time domain, in a reflex write implementation sequential color separations are written based on events in the spatial domain. Once the initial color separation is written, the distance that color separation travels is tracked until the color separation is under the next imaging station, where the next color separation is written properly registered with respect to the existing color separation. The imaging system includes a raster output scanner imager for the black station and a light emitting diode bar for the color station.
