Latest Patents

One of his latest patents is titled "Systems and methods for accessory and impedance detection." This invention describes systems and methods for reliably detecting the presence or absence of accessories and other components connected to an external electrical device or connector. A low-cost detection circuit is designed to distinguish between a compromised connector and the presence of an actual device, thereby preventing false detection scenarios. The detection circuit utilizes a zero-crossing detector and/or a digital signal, which serves as a measure of impedance, to detect the presence of the external device within an identification period.

Another significant patent is the "Method for providing power to an electronic device." This method involves connecting a power supply to a USB port of an electronic device and emulating a personal computer (PC) host system. This emulation allows the electronic device to believe that the power supply is a PC host system. The method includes retrieving at least one descriptor from the electronic device, identifying the electronic device from the descriptor, and setting a charging voltage based on the identity of the electronic device.
