Latest Patents

Cohen's latest patents include a communication system and an IoT system. The communication system is designed to operate within a wireless network that includes an access point. The IoT system features a WiFi module and a GPIO device. The WiFi module connects to the access point, while the GPIO device provides multiple wake-up signals to the WiFi module through a GPIO pin. Notably, the predetermined time period between any two wake-up signals exceeds the interval between two delivery traffic indication messages from the access point. Additionally, the WiFi module is equipped with a timer and a power management unit, which conserves power by transitioning the WiFi module from sleep mode to normal mode upon receiving a wake-up signal.

Another significant patent involves a method of saving power for a station in a wireless network. This method includes powering on the connectivity module, central processing unit, and peripheral devices upon receiving a wake-up signal. The central processing unit and peripheral devices operate in a connection state, while the connectivity module remains in an authenticated state. If there is no data to be transferred or after all necessary data has been transmitted and received, the system enters sleep mode to conserve energy.
