Abstract: A method is disclosed of providing instructions to a compiler system for specifying rules of behavior for a program. Rules are implemented by a message passing structure, wherein messages are passed between objects of the system. Each rule is defined by a structured script identifier, that uniquely characterizes the timing, level of detail and the grouping of a rule. Each rule is further defined by preconditions that determine when the rule applies, and the state of the system after it has been applied (postconditions). The behavior of a program can be specified so that rules can be applied to a system based on timing contraints, and/or in a logical order, based on the occurrence of logical conditions. The rules art executed by testing for preconditions subject to timing constraints, and asserting postconditions when the preconditions have been satisfied. Each rule has an attached label specifying a level of detail. Testing of the rules can be performed and displayed at any specified levels of detail.

Abstract: A distributed computer system, has a number of users and target applications. When a user logs on to the system, an authentication unit issues the user with a privilege attribute certificate (PAC) representing the user's access rights. When the user wishes to access a target application, he presents the PAC to that application as evidence of his access rights. The application, in turn, passes the PAC to a PAC use monitor (PUM) which validates the PAC. The PUM is shared between a plurality of applications.

Abstract: A distributed database management system includes a plurality of computers, each including a database for storing data to be processed. The plurality of computers are interconnected by communication lines. Each computer has stored data names, and corresponding address area and location information for all databases, and measures data retrieval time from the databases. A retrieval time memory section stores data retrieval times corresponding to the address areas of data stored in the databases. A retrieval time prediction section retrieves the data retrieval time for data corresponding to a data name requested by a user when the requested data is stored in at least two databases, utilizing stored data retrieval times and corresponding address areas and location information on where the data is stored. A data retrieval optimization section selects the database location information and the address area associated with the requested data name according to the retrieval result by the retrieval time prediction section, and retrieves the requested data from the appropriate database according to the location information and address area. The system can also register input data according to a desired retrieval time.

Abstract: An image signal processing apparatus wherein the black level of an analog image signal is adjusted by controlling the clamp level of the inputted analog image signal. The clamped analog image signal is digitalized. Using the digital image signal offset to a first level during the blanking period, the black level adjustment of the analog image signal is carried out. The first level during the blanking period of the digital image signal corresponding to the analog image signal with the black level having been adjusted, is changed to a second level, allowing a correct and easy black level adjustment using a simple circuit arrangement.

Abstract: A cache controller is coupled between a central processing unit (CPU) and a memory management unit (MMU). The MMU is coupled to main memory, and the cache controller is further coupled to a cache memory. A cache controller transfers a block of N programming instructions from the main memory into the cache memory. Once this transfer is complete, the CPU begins the sequential execution of the N instructions. Generally concurrently, the cache controller scans each of the N instructions to detect branch instructions. Branch instructions are those instructions which require additional data not found within the block of N instructions previously loaded into the cache. Upon detection a branch instruction, and prior to the execution of the branch instruction by the CPU, the cache controller fetches the branch instruction data from main memory, and stores it within the cache.

Abstract: A multipurpose system provides radar surveillance for air traffic control purposes. The system includes four separate active phased-array antennas, each with ± 45° coverage in azimuth, from 0° to 60° in elevation. Each antenna element of each phased-array antenna is coupled by a low-loss path to the solid-state amplifier associated with a transmit-receive (TR) module. Each antenna produces a sequence of pencil beams, which requires less transmitted power from the TR modules than a fan beam, but requires more time because the pencil beam must be sequenced to cover the same volume as the fan beam. In order to scan the volume in a short time, the PRF is responsive to the elevation angle of the beam, so higher elevation angles use a higher PRF. Low elevation angle beams receive long transmitter pulses for high power, and pulse compression is used to restore range resolution, but the long pulse results in a large minimum range within which targets cannot be detected. A second scan is provided at low elevation angles with a short transmitter pulse to fill in the short-range coverage. Beams at higher elevation angles transmit pulse widths which are shorter than beams at low elevation angles, so that the minimum range requirement is met without a second scan, which also reduces the time required for volumetric scan. The number of pulses which are integrated to produce a return increases off-axis, to restore system margin lost due to off-axis power gain reduction. The volumetric scan rate is increased by a dynamic scan regimen by which subsets of beams are pulsed with a high transmitter PRF but with a low effective beam PRF to reduce range ambiguity and preserve Doppler resolution without the usual increase of scan time. For best range resolution, Doppler processing is used, with range sidelobe pulse suppression applied separately to each Doppler frequency bin.

Abstract: A color video signal conversion apparatus includes a color decoder (52) by which a phase of an NTSC chrominance signal is decoded as a first color code on the basis of a first clock of 21 MHz. The first color code is further converted into a second color code representing a phase of a PAL chrominance signal by a code converter (54). A PAL chrominance signal is encoded by a PAL encoder (56) on the basis of the second color code and a second clock of 26 MHz. The PAL chrominance signal is synthesized with an original luminance signal, and a PAL composite synchronization signal is added thereto, whereby a PAL composite color video signal is obtained.

Abstract: A micro controller (MC) which is constructed as a pulse-width modulator changes the duty ratio (the modulation) of the pulse-width modulation output signal (MS) at a specific switching frequency, and drives the downstream push-pull stage (GS) in a time-delayed manner by means of at least one upper power switch and one lower power switch (LSO, LSU). The micro controller (MC) has three pulse-width modulation outputs (ports P1, P2, P3). The actual PWM output signal (MS) is emitted at the first output (P1). The modulation signal (MS) plus a dead time (MS + TZ) are emitted at the second output (P2) and fed to the lower power switch (LSU) as a drive signal (ASU). The dead time (TZ) is emitted at the third output (P3), the drive signal (ASO) for the upper power switch (LSO) being formed from the modulation signal (MS) and the inverted dead time (TZ) by subtraction (SUB). In the modulation limit region (modulation tending to 100% and 0%), the dead time (TZ) is reduced automatically and one power switch (LSU or LSO) is switched on continuously, while the other power switch (LSO or LSU) is switched off in the mean time. Beyond a specific modulation limit value, a "Power bit" (PB) is emitted regularly at a fourth output (P4) and produces 100% modulation. <IMAGE>
