  • Geo-verified delivery system
    Patent number: 11922364
    Abstract: A system and method for geo-certifying delivery of items is disclosed. In some embodiments, a system tracks the intended delivery addresses of items as well as the actual delivery points. The system then determines if it has geo-verified geo-coordinates for the intended delivery points. If so, the system geo-certifies a delivery if the actual delivery point is within a geofence surrounding the intended delivery address.

  • Lossless current sensing in buck converters working with low duty cycles and high clock frequencies
    Patent number: 6166528
    Abstract: A buck converter having a synchronous rectifier topology that performs current sensing at the low-side switch and employs "valley current control" to terminate a discharging phase and commence a charging phase of the converter. The buck converter is able to withstand high operating frequencies and low duty cycles to produce a low output voltage from a given high input voltage.
