A time-learning test system for running a test program on a device under test (DUT) is disclosed. A command is sent from a controller to an instrument. A preset wait period is observed in the test program. A response time of the instrument to the command is determined. The preset wait period is adjusted based on the response time.

A system and a method for displaying an emitter location are disclosed. The system includes a plurality of receivers at different locations in a field. Each receiver generates a receiver signal that depends on the magnitude of a signal from the emitter. The system also includes a processor that receives the receiver signal and generates a likelihood map indicative of an approximation of a probability as a function of position in the field of the emitter location. The likelihood map includes a plurality of receiver maps. Each receiver map includes a probability as a function of position in the field of the emitter location based on the signal magnitude for at least one of the receiver signals. Each receiver map may depend on a ratio of the signal magnitudes from a corresponding pair of the receivers, or on one of the signal magnitudes from a corresponding one of the receivers.

A method and apparatus for optimizing the voltage supply of an image sensor pixel array to minimize pixel noise and maximize dynamic range is disclosed. The voltage supply is adjusted in response to the exposure level of the pixel array when it captures an image. The voltage supply is increased in higher exposure levels to expand the dynamic range of the pixel array. In lower exposure levels, when the full dynamic range of the pixel array is not utilized, the voltage supply is decreased to lower pixel noise level and reduce its effect on image quality.

Labeling asymmetric network cables for improved network clock synchronization. Time asymmetries between pairs in a network cable are identified and associated with individual cables. This time asymmetry information is used to improve clock synchronization according to the IEEE-1588 standard. The time asymmetry information may be stored in a database and associated with a serial number on the cable, or may be associated with the cable in human and/or machine readable form.

Circuitry is included to recover the monitorable, e.g. GMII, interface into the path between the actual MAC/PHY device being used and the RJ45 connector to allow PTP circuitry to monitor the transmission and reception of the Ethernet Frames.

A sensor includes an array of photodetectors each generating an output signal of pixel data indicative of incident light intensity. This pixel data is read out from the array one line at a time and stored in a line buffer. A bad pixel processor includes a first buffer that stores pixel data obtained from the line buffer for a certain pixel in a currently read out line and pixel signal light data for pixels adjacent to the certain pixel.

An electrolytic cell is disclosed which comprises: (a) an electrolyte; and (b) a plurality of bipolar electrodes surrounded by the electrolyte and electrically connected in series during operation of the cell, the bipolar electrodes each comprising a cathode side, an anode side, and an electrically conductive connection between the cathode side and the anode side, wherein the cathode side and the anode side of at least one of the bipolar electrodes are movable and mechanically separable with respect to each other so that one of the two electrode sides can be removed from the cell, while the other electrode side remains in the cell.

A process is disclosed for preparing anhydrous alumina from aluminum hydroxide which comprises feeding aluminum hydroxide into a first suspension preheater and partially dehydrating the aluminum hydroxide with a hot exhaust gas, transporting the partially dehydrated aluminum hydroxide with said exhaust gas to a first separating means and separately withdrawing the exhaust gas and the partially dehydrated aluminum hydroxide, and dividing the partially dehydrated aluminum hydroxide into a first and second partial stream of solids. The process uses a circulating fluidized bed comprising a fluidized bed reactor, a recycle separator connected to the upper portion of said fluidized bed reactor, and a return line for leading solids from said recycle separator to the lower portion of said fluidized bed reactor. The second partial stream of solids is fed into a second suspension preheater and contacted with hot exhaust gas from the recycle separator. The solids and the exhaust gas are transported to a second separating means and an exhaust gas stream is withdrawn and fed into the first suspension preheater. A dehydrated solids stream is fed into the fluidized bed reactor and the reactor temperature is adjusted to 850 to 1000.degree. C. A third partial stream of solids is mixed with the first partial stream of solids to form a hot solids mixture. The hot solids mixture is cooled in at least one fluidized bed cooler and then is fed into the fluidized bed reactor. The hot solids mixture is cooled in at least one fluidized bed cooler.

A temperature measurement device for rotary kilns comprises a stripping sleeve rigidly mounted in a bore or the shell of a rotary kiln and has one end portion extending into the rotary kiln. A ceramic ring is mounted at the one end portion of the sleeve and a protective tube is slidably mounted in the stripping sleeve and through the opening in the ceramic ring. A thermocouple is disposed in the protective tube at one end portion thereof that corresponds to the one end portion of the stripping sleeve. The protective tube is lifted to retract its one end portion until the end thereof is disposed in the ceramic ring thereby scraping off any crust thereon and the tube is then lowered to such an extent that the one end portion thereof protrudes from the ceramic ring so that temperature measurement can be effected.
