A temperature sensor utilizing optical temperature measuring techniques is constructed to make firm contact with a surface whose temperature is being measured, an example application being the monitoring of semiconductor wafers or flat panel displays while being processed. A cap is mounted near but spaced apart from an end of a lightwave guide, with a resilient element that applies force of the cap against a surface whose temperature is being measured as the cap is urged toward the optical fiber end. An optical temperature sensing element, such as luminescent material or a surface of known emissivity, is carried within the cap. A bellows with a closed end conveniently serves as both the cap and the resilient element. An alternative temperature measuring device installs an optical temperature sensing material within a test substrate behind an optical window, and then views the sensing material through the window.

Abstract:
A system and method for efficiently performing timing characterization of regions of an integrated circuit. An integrated circuit has monitors distributed in different physical regions across its die. Each monitor includes timing characterization and self-test circuitry. This circuitry includes one or more tunable delay lines used during timing measurements. The circuitry verifies the tunable delay lines are defect free prior to the timing measurements. If defects are detected, but tunable delay lines may still be used, a scaling factor may be generated for a failing tunable delay line. The scaling factor may be used during subsequent timing measurements to maintain a high accuracy for the measurements. The timing measurements may determine a particular physical region of the die provides fast or slow timing values. The resulting statistics of the timing measurements may be used to change an operational mode of the IC in at least the particular region.

International Classification:
G01R 31/26
US Classification:
32476201
Abstract:
A system and method for testing circuits. A generated input voltage waveform for a first phase of a test may use transitions with a voltage swing between expected low and high trigger points for an integrated circuit (IC) with hysteresis. A generated input voltage waveform for a second phase of the test may use transitions with a voltage swing between the expected low trigger point and a high sub-threshold value. The high sub-threshold value may be a tolerable voltage difference below the expected high trigger point. A generated input voltage waveform for a third phase of the test may use transitions with a voltage swing between the expected high trigger point and a low sub-threshold value. The low sub-threshold value may be a tolerable voltage difference above the expected low trigger point. The expected trigger points and sub-threshold values may be found from earlier characterization studies for the IC.

International Classification:
G01R 31/3177 G06F 11/25
US Classification:
714726, 714E11155
Abstract:
A method and apparatus for detecting clock glitches during at-speed testing of integrated circuits is disclosed. In one embodiment, an integrated circuit includes a scan chain having a number of scan elements coupled in a series configuration. Each of the scan elements is coupled to receive a clock signal that may be cycled during a test operation. A subset of the scan elements are arranged to form, along with other components, a counter. Test stimulus data shifted into the scan chain to perform a test may include an initial count value that is shifted into the scan elements of the counter. When the test is performed, the count value is updated responsive to cycling of the clock signal. The updated count value is shifted from the counter along with other test result data, and may be used to determine if the number of clock cycles received during the test.
The present invention relates generally to surgical lasers and more specifically to a laser beam control and delivery system that accurately and efficiently directs a laser beam into an optical fiber. The laser beam control and delivery system also provides additional functions, including a connection for a fiber tip temperature control system and a tissue temperature sensing system. The present invention also relates to a surgical laser system that has a high efficiency thermoelectric cooling system.

Abstract:
Systems and methods for anomaly detection are provided. In one example embodiment, a computer-implemented method includes obtaining, by a computing system including one or more computing devices, state data indicative of one or more states of one or more objects that are within a surrounding environment of an autonomous vehicle. The method includes determining, by the computing system, an existence of an anomaly within the surrounding environment of the autonomous vehicle based at least in part on the state data indicative of the one or more states of the one or more objects within the surrounding environment of the autonomous vehicle. The method includes determining, by the computing system, a motion plan for the autonomous vehicle based at least in part on the existence of the anomaly within the surrounding environment of the autonomous vehicle.
