Patent number: 8963520Abstract: A system includes a feedback module that communicates with a capacitor connected across an output of a power converter and that generates a feedback voltage indicating a pre-bias voltage across the capacitor before power is supplied to the power converter. A comparator compares the feedback voltage to a reference voltage and determines whether the pre-bias voltage across the capacitor is greater or less than a desired output voltage of the power converter when power is supplied to the power converter. A ramp generator module generates a first or second ramp if the pre-bias voltage is less or greater than the desired output voltage. A control module drives high-side and low-side switches to charge or discharge the capacitor from the pre-bias voltage to the desired output voltage based on the first or second ramp and controls the power converter after a voltage across the capacitor reaches the desired output voltage.Type: GrantFiled: March 12, 2013Date of Patent: February 24, 2015Assignee: Maxim Integrated Products, Inc.Inventors: Salvatore Leone, Andrea Milanesi

Patent number: 6366724Abstract: The present invention is a module for use in an optical fiber administration system, or a dedicated system. The module contains both an optical transmitter and an optical monitor, wherein the module transmits a test signal over a fiber optic network and receives back that same signal through a different fiber in the fiber optic network. By both sending and receiving the test signal, the integrity of different paths in the optical fiber network can be determined in a space efficient manner. The module contains a microprocessor. The microprocessor reads data regarding the test signal as it is transmitted and that same test signal as it is received. This data may be read to an external shelf controller.
