Latest Patents

Watson’s patent, “PIR Sensing Circuit for a Consumer Electronic Device,” describes a device that uses a low-power sensor, such as a pyroelectric infrared (PIR) sensor, to detect a person and switch the device from standby to full-power mode.

The sensor can produce a small analog signal for a microcontroller to amplify and convert into a digital signal. The microcontroller can also supply power to the sensor using an integrated reference voltage source and operational amplifier. This approach is designed to provide a stable, low-power supply, reduce noise and false triggering, and avoid the need for a separate power supply. By reducing component count, the circuit may also support a more compact, lower-cost design.
