Title: Method and apparatus for testing image sensing circuit arrays
Inventor: SCOTT-THOMAS JOHN
IPC: H01L31/10
Filed: 2001-03-13
Granted: 2007-08-07
Abstract: A method and apparatus for testing an image sensor array such as a C-MOS  imager which has sensing circuits arranged in rows and columns and wherein the sensing circuits include photosensitive devices is described. A reset voltage is applied to the photosensitive device in each of the sensor circuits such that at least adjacent circuits are reset to different voltage levels. The voltage on each photosensitive device is detected and compared to an expected level to determine if and where any faults may exist in the sensing circuits or lines in the array. A different reset voltage may be applied to each of the sensor circuits, however in one embodiment, a supply with only two voltage levels may be used. One voltage level is applied to every second column to provide a supply voltage to the photosensitive devices and to every second row to generate a reset enable signal for the photosensitive devices. The second voltage level is applied to the remaining columns and rows resulting in different reset voltage levels on adjacent sensing circuits.

Abstract: A system and method for characterizing the contents of an input audio signal and for suppressing noise components of the input audio signal are described.  The audio signal is divided into a number of frequency domain input signals. Each frequency domain input signal can be processed separately to determine its intensity change, modulation frequency, and time duration characteristics to characterize the frequency domain input signal as containing a desirable signal or as a type of noise.  An index signal is calculated based on a combination of the determined characteristics and signals identified as noise are suppressed in comparison to signals identified as desirable to produce a set of frequency domain output signals with reduced noise. The frequency domain output signals are combined to provide an output audio signal corresponding to the input audio signal but having suppressed noise components and comparatively enhanced desirable signal components.

Abstract: A deceleration sensor includes a pendulum which is suspended within an U--shaped bucket. The pendulum carries a permanent magnet which is adjacent to a Hall Effect device mounted upon the bucket. Both the pendulum and bucket are carried in an open ended housing which permits movement of the bucket relative to the pendulum to adjust for surface angles when the sensor is mounted upon a vehicle.  Upon the deceleration of the vehicle, the pendulum move relative to the Hall Effect Device. As a result of the changing magnetic field, a voltage is generated by the Hall Effect Device which is directly proportional to the vehicle deceleration.

Abstract: The invention relates to a method of correcting local, machine-based inking nonuniformities on rotary printing machines, in which the following method steps are executed:      Firstly, the inking behavior of the printing units of a multicolor rotary printing machine is determined by means of test plates. The inking nonuniformities on the test plates are transmitted to the pre-press stage. Using the data about the inking nonuniformities of the test plates, the raster tonal values of the color separations of a printing plate are modified in such a way that the inking nonuniformities are maintained locally on the basis of the location of their occurrence in the print on the printing plates or films.
