Methods and systems are disclosed for determining sensor degradation by actively controlling an autonomous vehicle. Determining sensor degradation may include obtaining sensor readings from a sensor of an autonomous vehicle, and determining baseline state information from the obtained sensor readings. A movement characteristic of the autonomous vehicle, such as speed or position, may then be changed. The sensor may then obtain additional sensor readings, and second state information may be determined from these additional sensor readings. Expected state information may be determined from the baseline state information and the change in the movement characteristic of the autonomous vehicle. A comparison of the expected state information and the second state information may then be performed. Based on this comparison, a determination may be made as to whether the sensor has degraded.

The present invention provides procedures and systems that use a closed-loop approach for directing ultrasound energy at a clot while monitoring blood flow and / or liquification of the clot tissue so as to allow automated and / or manual adjustments to various treatment parameters.

When the film thickness of an insulating film on a fuse connected to a circuit is not uniform within a wafer surface, there was a problem that disconnection of the fuse might become insufficient due to the insufficient intensity of a laser or disconnection of even an adjacent fuse due to excessive laser irradiation might occur. Further, a problem also occurred that after disconnection of the fuse, moisture entered from exterior through the region in which the fuse has been disconnected, so that the quality of a film underlying the fuse was adversely affected. After a SiON film, a SiN film, and a SiO2 film have been formed to cover the fuse in this stated order, etching is performed to the SiN film, which is an etching stopper film. The SiON film having a uniform and desired film thickness is thereby formed on the fuse.

The present invention includes compositions and methods for making and using an isolated cyanobacterium that includes a portion of an exogenous bacterial cellulose operon sufficient to express bacterial cellulose, whereby the cyanobacterium produces extracellular glucose. The compositions and methods of the present invention may be used as a new global crop for the manufacture of cellulose, CO2 fixation, for the production of alternative sources of conventional cellulose as well as a biofuel and precursors thereof.

An organic semiconductor device in which recombination of holes and electrons and photoelectric conversion in an organic semiconductor layer are efficiently allowed to occur. The device comprises a bipolar organic semiconductor layer where electrons and holes move, a hole giving / receiving electrode which gives / receives holes to / from the organic semiconductor layer, an electron giving / receiving electrode which is spaced a predetermined distance from the hole giving / receiving electrode and gives / receives electrons to / from the organic semiconductor layer, a hole-side gate electrode which is opposed to a region of the organic semiconductor layer near the hole giving / receiving electrode with an insulating layer between the hole-side gate electrode and the region and serves to control the hole distribution in the organic semiconductor layer, and an electron-side gate electrode which is opposed to the region of the organic semiconductor layer with the insulating layer therebetween and serves to control the electron distribution in the organic semiconductor layer.
