Publication number: 20140335851Abstract: The invention relates to a method for deactivation of at least one first cell of a plurality of cells in a telecommunications network. User devices in the at least one first cell are triggered to report measurement information regarding one or more second cells of the plurality of cells to the telecommunications network. The measurement information is received in the telecommunications network and analyzed in order to determine whether one or more user devices in the at least one first cell are eligible for being served by a second cell of the one or more second cells when the at least one first cell would be deactivated. When the one or more user devices are determined to be eligible for being served by the second cell of the one or more second cells, the one or more user devices are transferred and the at least one first cell is deactivated.Type: ApplicationFiled: July 29, 2014Publication date: November 13, 2014Applicants: Koninklijke KPN N.V., Nederlandse Organisatie voor Toegepast- Natuurwetenschappelijk Onderzoek TNOInventors: Ljupco Jorguseski, Remco Litjens, Haibin Zhang

Publication number: 20140093693Abstract: Methods and apparatus for separating substrates are disclosed, as are articles formed from the separated substrates. A method of separating a substrate having first and second surfaces includes directing a beam of laser light to pass through the first surface and, thereafter, to pass through the second surface.

Relative motion between the beam of laser light and the substrate is caused to scan a spot on a surface of the substrate to be scanned along a guide path. Portions of the substrate illuminated within the spot absorb light within the beam of laser light so that the substrate can be separated along the guide path.Type: ApplicationFiled: December 2, 2013Publication date: April 3, 2014Applicant: ELECTRO SCIENTIFIC INDUSTRIES, INC.Inventors: Haibin ZHANG, Qian XU

Publication number: 20130193617Abstract: A non-metallic material is separated using a single laser beam that is converted into a scribe beam and a break beam. A system includes a single laser source for generating a laser beam and a beam separator for converting the laser beam into a scribe beam having a first average power and a break beam having second average power. The beam separator directs the scribe beam to a scribe line on a substrate and the break beam to the substrate at a location that is spaced apart from the scribe beam. The scribe beam rapidly heats the substrate along the scribe line. A quenching subsystem applies a stream of cooling fluid to the substrate to propagate a microcrack along the scribe line. The break beam rapidly reheats the substrate quenched by the stream of cooling fluid to separate the substrate along the microcrack.Type: ApplicationFiled: February 1, 2012Publication date: August 1, 2013Applicant: ELECTRO SCIENTIFIC INDUSTRIES, INC.Inventor: Haibin Zhang
