Latest Patents

One of his latest patents is titled "Closed-loop efficiency modulation for use in network powered applications." This patent discloses methods for reducing power dissipation from an input power source in a telecommunications system. In one embodiment, the method includes utilizing a first I2C device to monitor input voltage and current to a remote unit. The input voltage and current are then provided to a main microprocessor for calculating input power. Additionally, a second I2C device monitors output voltage and current from the remote unit, allowing the main microprocessor to calculate output power. The efficiency of the remote unit is calculated based on these inputs, and a digital power manager is utilized to control the output to a DC/DC converter.

Another patent under his name also focuses on closed-loop efficiency modulation. This patent describes a method and a remote device, such as a sealed expansion module (SEM), for reducing power dissipation in telecommunications systems. The SEM contains a network feed monitor that receives input voltage and current on twisted wire pair cables. The input voltage is transmitted to a DC/DC converter, which adjusts the voltage before sending it to a BUS feed monitor connected to an active load. The main microprocessor calculates input and output power, optimizing system efficiency through a digital power manager.
