Patent number: 9304150Abstract: A current probe enabling measurement of current of a signal in a circuit includes a ferrite core defining a gap, a wire wrapped around the ferrite core and a magnetic field sensor. The wire is configured to receive the signal from the circuit, where the current of the signal flowing in the wire generates a magnetic field in the ferrite core. The magnetic field sensor is positioned in the gap of the ferrite core, the magnetic field generated in the ferrite core flowing through the magnetic field sensor, which produces a voltage proportional to an intensity of the magnetic field. The current is measured based on the voltage produced by the magnetic field sensor.Type: GrantFiled: September 30, 2011Date of Patent: April 5, 2016Assignee: Keysight Technologies, Inc.Inventor: Kenneth W.

Patent number: 8658918Abstract: A fast heat transfer device is provided. The device dissipates heat and generates power at the same time. A liquid flow is used to absorb heat for forming a vapor gas flow; then, the gas flow drives a blade turbine and a power generator; and, finally, the gas flow is cooled down to become the original liquid flow for recycling. Thus, the present invention dissipates heat and generates power simultaneously with a minimized size and a reduced cost together with energy conservation.Type: GrantFiled: September 7, 2012Date of Patent: February 25, 2014Assignee: Institute of Nuclear Energy Research, Atomic Energy CouncilInventors: Heng-Yi Li, Chun-Wei Yang, Shih-Tse Chang, Tsair-Fuh Huang, How-Ming Lee, Chin-Ching Tzeng
