Latest Patents

One of Butler's latest patents is focused on detecting connection to a USB host or hub without using an extra status input. This low power Universal Serial Bus (USB) capable device utilizes a weak pull-up resistance coupled to at least one data line of the USB. This design allows for the detection of when the USB capable device is connected to a USB host or hub. When not connected, the USB peripheral, including the USB transceiver, voltage regulator, and logic circuits, can be powered down to conserve energy. Conversely, when connected, the voltage from the weak pull-up is significantly reduced, signaling that the USB peripheral should be powered up for normal operation.

Another notable patent by Butler involves a digital system that has a selectable clock speed based on the available supply voltage and phase-lock-loop (PLL) configuration register settings. In this system, the clock speed is controlled according to the supply voltage to the digital device. If the supply voltage is below a reference voltage, the clock speed is slower, while a higher supply voltage allows for a faster clock speed. This innovation enables a USB device to operate at varying clock speeds depending on the operating voltage, enhancing its efficiency.
