Abstract: A computer program controlled method of processing geometric objects constructs a binary tree data structure 10 associated with bounding boxes of geometric objects. For each bound of a bounding box there is found a median (X) of all corresponding bounds, such as left sides associated with the bounding boxes. Next, all of the bounding boxes having a minimum bounding value less than X are placed on a left sub-­tree 12 of the tree. All of the bounding boxes having a minimum bounding value greater than X are placed on a right sub-tree 14 of the tree. At the root are placed values that represent the maximum of that dimension's values in the left sub-tree and the minimum of that dimension's values in the right sub-tree. Boxes assigned to the left sub-tree and to the right sub-tree are similarly processed using a next bound such as the right sides. Searching the binary tree data structure in response to a query interval or box determines all of the boxes overlapping the Q box by comparing a lesser Q box bound with the left sub-tree's maximum value and by comparing a larger Q box bound with the right sub-tree's minimum value. The comparison generates information specifying if further search is carried out on the left sub-tree, the right sub-tree or on both sub-trees. Steps of the method are accomplished a plurality of times with successive bounds and recycling as required until the leaves of the tree are reached.

Abstract: A method of mandatorily enforcing security protections to insure access to files of a computer system only to computer processes properly authorized for access. A separate security label is associated with each file and process of the system and defines authorized security classes pertaining to the associated file or process. Each security label contains information describing authorizations based on data secrecy and data integrity. A comparison is made on an attempted access of a file by a process of the security label associated with the process and the security label associated with the file. A verification is made based on the comparison that the process is authorized to access the file. The verification as to both secrecy and integrity aspects is accomplished in the single verification step.

Abstract: A digital switcher routes signals at rates up to or more than 300 MHz between switcher inputs and outputs. The switcher includes an array of  n  rows and  m  columns of modules linking  n  groups of switcher inputs and  m  groups of switcher outputs. Each module consists of a primary switching unit (A1) for selectively coupling individual ones of its outputs to ones of its inputs and a number of individually-controllable, regenerative, two-input selector switches (A2). The primary and selector switches are controlled by a controller (20). The selector switch outputs form the module outputs. Each selector switch has an input connected to an associated output of the primary switching unit in the same module, and the other connected to an associated output of a module in the previous row of the array (apart from those in the first row). The switcher outputs are derived from the outputs of the last row of modules. 
     To route a signal from a switcher input to a selected switcher output, the appropriate primary switching unit to which that switcher input is fed links its corresponding input to the selected one of its outputs. The regenerative selector switches in that module and in modules in subsequent rows then cascade the signal from that module through the subsequent rows to the selected switcher output.

Abstract: One or more seismic sources impart seismic pulses into the earth in a coded sequence. The coded sequence is composed of a minimum of three cycles of a Galois sequence of order N, where N is a positive integer. The response of subsurface formations to the coded sequence is obtained and correlated with one cycle of the outgoing Galois sequence of the same order. Correlation properties of the Galois sequences provide a way to sum a large number of seismograms that are superimposed in time, improving the signal to noise ratio while keeping the field time in which the seismograms are obtained to a minimum. Using this encoding technique, responses of subsurface formations to concurrent activation of each of several sources can be obtained and separated from each other.

Abstract: The balance of the volumes in right and left channels in a stereo play back system is controlled. The amount of attenuation of an attenuator provided in each channel is controlled. When the levels of right and left stereo signals are judged to be approximately the same, an oscillator is permitted to oscillate and the pulses from the oscillator are counted by a counter. In accordance with a voltage signal which corresponds to the level ratio of the right and left stereo signals, whether the counter must count upwards or downwards is determined. The balance is controlled in accordance with the amount of attenuation of each attenuator which is determined in accordance with the decoded count value. The completion of the control is detected when the level ratio of the right and left stereo signals alternately change after they become substantially equal, and the control is automatically finished. When the control is finished, the counter is reset so as to facilitate balance control when the source of the stereo signals is changed.

Abstract: A reversible control apparatus for controlling a motor is provided which is highly durable, weather proof, simple in structure and inexpensive to manufacture. The motor (1) is controllably driven by a motor driver (3). A target rotational speed determiner (5) determines a target rotational speed for the motor and generates a corresponding output signal. A rotational speed sensor (2) senses the rotational speed of the motor and generates a corresponding output signal having no polarity which indicates the direction of rotation of the motor. A motor controller (4) controls the motor driver. A polarity applying means (6) applies a polarity to the output signal of the rotational speed sensor (2) on the basis of the output signal of the target rotational speed signal and the output signal of the motor controller (4). The polarity applying means (6) further determines whether there is agreement therebetween the direction of rotation of the target rotational speed signal and that of the output signal of the motor controller and generate, if there is disagreement therebetween, a motor driver control signal for making the output signal of the motor controller to zero until the direction of rotation of the target rotational speed signal coincides with that of the output signal of the motor controller. A subtracter (7) generates a deviation signal representative of a deviation between the target rotational speed signal and the polarity-applied rotational speed signal to the motor controller.

Abstract: A semiconductor device defines a thyristor (4,5,8,9) in which connection is made to the cathode region (9) of the thyristor by means of a MOS structure. The MOS structure is provided by a fifth region (11) forming a pn junction with the cathode region (9), a sixth region (13) in contact with the cathode electrode (C) and forming a pn junction (14) with the fifth region (11), and an insulated gate (15) overlying a conduction channel area (110) of the fifth region (11) for defining a gateable conductive path for charge carriers into the cathode region (9) to initiate thyristor action. The conductive path is thus controlled by the voltage applied to the insulated gate (15) enabling the flow of charge carriers to the cathode region (9) to be stemmed by application of an appropriate gate voltage oxide. The fifth region (11) is electrically connected to provide a path for extraction of charge carriers during turn-off of the thyristor thereby improving the controllable current capability of the thyristor.
