Patent number: 7211980Abstract: Robot platforms, methods, and computer media are disclosed. The robot platform includes perceptors, locomotors, and a system controller, which executes instructions for a robot to follow a target in its environment. The method includes receiving a target bearing and sensing whether the robot is blocked front.

Patent number: 7212008Abstract: An apparatus for detecting concealed surveillance devices coupled to a transmission line uses either a time domain or frequency domain reflectometry operation to locate any impedance anomalies on the transmission line and a non-linear junction detection operation to classify the located impedance anomalies as semiconductor or non-semiconductor based anomalies.

Patent number: 7212017Abstract: Provided is a sample observing method allowing for a detailed observation of a sample by using one and the same electron beam apparatus. The method uses an electron beam apparatus 1 comprising a primary optical system 10 serving for irradiating the electron beam onto the sample surface and a secondary optical system 30 serving for detecting secondary electrons emanating from said sample surface to form an image of the sample surface. The inspection is carried out on the sample surface, S, by irradiating the electron beam to the sample surface, and after the extraction of a defective region in the sample based on the inspection, the extracted defective region is once again applied with the irradiation of the electron beam so as to provide a magnification or a detailed observation of the defective region.Type: GrantFiled: December 22, 2004Date of Patent: May 1, 2007Assignees: Ebara Corporation, Kabushiki Kaisha ToshibaInventors: Kenji Watanabe, Tohru Satake, Nobuharu Noji, Takeshi Murakami, Tsutomu Karimata, Yuichiro Yamazaki, Ichirota Nagahama, Atsushi Onishi

Patent number: 7212018Abstract: A locking mechanism and method for selectively fixing and allowing movement of a tip portion of a probe relative to a rigid portion of the probe are provided. The mechanism comprises a locking ball joint for selectively locking and allowing relative movement between the tip portion and the rigid portion and a sleeve about the ball joint. The locking ball joint is locked by the placement of the sleeve in a first position, thereby fixing the position of the tip portion relative to the rigid portion, and released by the placement of the sleeve in a second position, thereby allowing movement of the tip portion relative to the rigid portion.Type: GrantFiled: October 21, 2004Date of Patent: May 1, 2007Assignee: LeCroy CorporationInventors: James Annichiarico, Michael Mannino

Patent number: 7212020Abstract: A circuit for isolating a short-circuited integrated circuit (IC) formed on the surface of a semiconductor wafer from other ICs formed on the wafer that are interconnected with the short-circuited IC includes control circuitry within the short-circuited IC for sensing the short circuit. The control circuitry may sense the short circuit in a variety of ways, including sensing excessive current drawn by the short-circuited IC, and sensing an abnormally low or high voltage within the short-circuited IC. Switching circuitry also within the short-circuited IC selectively isolates the short-circuited IC from the other ICs on the wafer in response to the control circuitry sensing the short circuit. As a result, if the wafer is under probe test, for example, testing can continue uninterrupted on the other ICs while the short-circuited IC is isolated.Type: GrantFiled: April 24, 2006Date of Patent: May 1, 2007Assignee: Micron Technology, Inc.Inventors: Warren M.

Patent number: 7212021Abstract: A method for designing and testing on-die power supply, power distribution, and noise suppression techniques for integrated circuits such as microprocessors is described. A network of time varying loads is distributed along the power supply grid to facilitate testing of new power supplies and grids and noise suppression techniques before design of the chip is completed. Several programmable current sinks are described for presenting loads according to a preferred test-waveform current. Transient, including droop detection, and static testing is easily performed using the described methods and circuitry.Type: GrantFiled: March 12, 2002Date of Patent: May 1, 2007Assignee: Intel CorporationInventors: Tanay Karnik, Peter Hazucha

Patent number: 7212022Abstract: An integrated circuit, in accordance with one embodiment of the present invention, includes a first device under test (DUT) module coupled to a first ring oscillator module and a second DUT module coupled to a second ring oscillator module. A dielectric layer of the first DUT is stressed during a first mode, thereby causing time dependent dielectric breakdown in the first dielectric layer. A dielectric layer of the second DUT is maintained as a reference. The operating frequency of the first ring oscillator module, during a second mode, is a function of a gate leakage current of the stressed dielectric layer. The operating frequency of the second ring oscillator module, during the second mode, is a function of a gate leakage current the reference dielectric layer. The integrated circuit may also include a comparator module for generating an output signal as a function of a difference between the operating frequency of the first and second ring oscillator modules.Type: GrantFiled: June 16, 2004Date of Patent: May 1, 2007Assignee: Transmeta CorporationInventor: Shingo Suzuki

Patent number: 7212025Abstract: A testing method for an array substrate is disclosed which includes a first measuring step of operating a line electrode driver circuit 15 and a row electrode driver circuit 16 like in a normal display mode while implementing writing in/reading out of a test video signal to and from supplemental capacitors 13, and a second measuring step of implementing writing in/reading out of the test video signals to and from a video bus 163 while rendering TFTs 11 of a pixel section 18 and analog switches 162 of the row electrode driver circuit 16 to be held turned off. Obtaining a difference between a measured result of the first measuring step and a measured result of the second measuring step allows only a pixel component and a row electrode component with no driver component to be derived, whereupon discrimination is implemented for the presence of or the absence of electric defects in the pixel section.Type: GrantFiled: January 11, 2006Date of Patent: May 1, 2007Assignee: Kabushiki Kaisha ToshibaInventor: Satoru Tomita
