Patent number: 7734436Abstract: The comparative analysis of a sample, derived from a product, with respect to a database comprises the step of determining the class membership of the different characteristics (variables) describing the samples: whether they are characteristics common to the sample under test and the database, they are characteristics particular to the sample under test, or they are characteristics particular to the database. The assignment of the variables to these classes enables parameters to be defined for global comparison of the sample under test and the database, based on: ratios summarizing the values taken by the variables of the different classes, or the distribution of the variables of the different classes. A machine implementation of the analysis is described.Type: GrantFiled: April 11, 2007Date of Patent: June 8, 2010Assignee: Alpha M.O.S.Inventors: Saïd Labreche, Hicham Amine, François Loubet, Eric Chanie, Jean-Christophe Mifsud

Publication number: 20100131221Abstract: The invention provides a method for determining quality parameter and the electronic apparatus using the same. The electronic apparatus includes a central processing unit (CPU) and a memory module. The method includes the following steps: performing a CPU overclocking process to obtain a highest operable CPU frequency; tuning a quality parameter and performing a memory test to obtain a test result; and determining an optimal value based on the test result to be a default value of the quality parameter.Type: ApplicationFiled: November 26, 2009Publication date: May 27, 2010Inventor: Chih-Sheng Chien

Patent number: 7725278Abstract: After completion of an arbitrary device process, an apparatus for micro-sample extraction extracts a part of a wafer as a micro-sample of a size equal to or larger than a repetition pattern with a probe and places the extracted micro-sample to a micro-sample storage, and the micro-sample storage is stored into an apparatus for micro-sample storage. The wafer is subjected to a post process and an observation desired position is determined in response to a failure analysis requirement. After that, the micro-sample is unloaded from the micro-sample storage by an apparatus for additional processing of the micro-sample and is placed onto an observation sample holder. By performing an additional process in the observation desired position, a failure analysis sample is prepared, and analysis information obtained by an apparatus for failure analysis is output.Type: GrantFiled: January 3, 2007Date of Patent: May 25, 2010Assignee: Hitachi High-Technologies CorporationInventors: Satoshi Tomimatsu, Hiroyasu Shichi, Muneyuki Fukuda, Kaoru Umemura

Patent number: 7724154Abstract: System and method for monitoring food storage bins. The system may include at least one food storage bin defining a volume usable to store food. Each food storage bin may also include at least one sensor usable to measure temperature within the volume. The system may include a transmitter/receiver operable to wirelessly transmit power to the at least one sensor and wirelessly receiver signals which include information regarding the temperature within the volume and/or the content of the food storage bin. The system may also include a controller coupled to the transmitter/receiver, operable to receive and/or determine information regarding the temperature, location, and/or content of the food storage bins via signals received from the transmitter/receiver. The controller may be operable to store the received information in a memory, e.g., comprised in or coupled to the controller.Type: GrantFiled: October 30, 2006Date of Patent: May 25, 2010Assignee: Acumera, Inc.Inventors: Brett B.

Publication number: 20100118314Abstract: Apparatus is disclosed for determining the track of origin of a cigarette manufactured in a cigarette making machine having a plurality of tracks. The cigarette making machine (60) is arranged such that the circumferential position of the tipping paper seam and the circumferential position of the tobacco wrapping paper seam are different for different tracks. The apparatus comprises a detector (20, 22; 36; 50) arranged to detect radiation from the cigarette (18) and to produce a signal representative of the detected radiation, and a processor (30; 54) arranged to process the signal produced by the detecting means to identify a shadow cast by a tipping paper seam and a shadow cast by a wrapping paper seam.Type: ApplicationFiled: November 10, 2009Publication date: May 13, 2010Inventors: Honey Jose, Ian Tindall, John Sanders
