20100214708 | System and Method for Using a PHY to Locate a Thermal Signature in a Cable Plant for Diagnostic, Enhanced, and Higher Power Applications - A system and method for using a physical layer device to locate a thermal signature in a cable plant for diagnostic, enhanced, and higher power applications. Cable heating in specific sections of a network cable is detected through an automatic identification of a thermal signature in electrical measurements of a network cable. The correlation of the thermal signature to a specific section of the network cable enables network personnel to locate hot spots in the network cable with ease. | 2010-08-26 |
20100214709 | METHODS AND SYSTEMS RELATING TO OVERCURRENT CIRCUIT PROTECTION - Systems and methods for providing overcurrent circuit protection are disclosed. A method of providing overcurrent circuit protection may include setting a threshold current value according to an operational state of a motor and sensing an amount of current being supplied to the motor. The method may further include electrically isolating the motor from a current source if the sensed current amount is greater than the threshold current value. | 2010-08-26 |
