Abstract: A vehicle control apparatus and method therefor has a number of controllers (50, 63, 56) interconnected with one another by a data highway (10), the engine controllers being formed for example by a CPU. The engine controllers are each connected to a sensor for sensing a vehicle parameter and the controllers are also connected to a respective actuator (53, 58) for varying the associated vehicle parameter. The apparatus is arranged so that the controllers operate in cooperation with one another so that two or more controllers cooperate to control the same object or purpose. As an example (shown in Figure 20) an engine controller (50) provides torque data to a transmission controller (63) which in turn provides data to a throttle controller (56), whereby a gear shift is effected by the transmission controller (63) in synchronism with the throttle controller (56) changing the position of a throttle actuator so that a jerk-free gear shift is effected. In another embodiment (shown in Figure 33) an engine controller (50) cooperates with a throttle controller (56) and a suspension controller (64) whereby data from the engine controller determining whether the vehicle is accelerating or braking is transmitted to the throttle controller (56) and the suspension controller (64) and the throttle position is adjusted in synchronism with the suspension controller (64) for adjusting the front-back ride height of the vehicle. Thus, for example, when the vehicle is braking, the throttle controller closes the throttle and the suspension controller increases the ride height of the front dampers and reduces the ride height of the rear dampers. Other embodiments control ignition timing and fuel injection in cooperation with gear shift (Figure 37), control fuel injection pulse width and ignition timing in cooperation with a knock detector controller (Figure 49), and upon detection of abnormal data received from sensors display a warning of the abnormality, and in the event of seriously abnormal data being detected transmits a pseudo signal to ensure that the vehicle keeps running.

Abstract: A pseudo-random synthesized signal is provided by analysis of a plurality of related signals by vector quantization of linear predictive coding coefficients (cluster representatives) of time blocks of the signals and providing cumulative probability matrices for the transition from one cluster representative for one block to a cluster representative of the next successive block of each of the signals. Synthesis of the pseudo-random signal is provided by randomly selecting according to a cumulative transition probability, the cluster representative of a next successive block given the selected cluster representative of the previous block, the coefficient of each block time being applied to a noise-excited recursive filter to generate the pseudo-random synthesized signal. A timing pulse generator (81) produces a pulse every T milliseconds, where T is the block time. A block number generator (82) in response selects a block address in a sequence in a block memory (83), which causes a pointer (cluster number) for a block K to be read from memory (83) to a cluster coefficient memory (70), and cumulative probabilities to be read to a comparator (62) that compares them with a random number from a random number generator (63) triggered by the timing pulse. The comparator (82) thereby provides a cluster number and cumulative probability for block (K+1). The cluster coefficient memory (70) loads an LPC recursive filter (84) with LPC coefficients.

Abstract: A detecting system is provided for detecting an insufficient amount of refrigerant in a cooling apparatus having a refrigerant circuit (11) which includes a compressor (12), a condenser (13) and an evaporator (16). The system has a refrigerant state detecting sensor (19, 30) provided in a high-pressure side path of the refrigerant circuit (11) for detecting an insufficient amount of refrigerant in the circuit (11) by sensing a mixing state of refrigerant in a liquid phase and refrigerant in a vapor phase. The detecting system is incorporated into a compressor control system having a compressor deactivating circuit coupled to the refrigerant state detecting sensor (19, 30) for deactivating the compressor (12) in response to a signal provided by the refrigerant state detecting sensor (19, 30). The refrigerant state detecting sensor (19, 30) determines that an insufficient amount of refrigerant exists at an early stage by detecting the mixing state of refrigerant. Since the compressor (12) is stopped at an earlier stage than in conventional systems, undesirable drive of the compressor (12) and damage to the compressor (12) can be prevented.

Abstract: A scan reading method according to this invention comprises the steps of: causing a line memory to store read original image data for one line; obtaining a density average value of one-line image data or a variation rate thereof; and detecting the edge of the original by comparing the average density value or the variation rate thereof with a predetermined threshold value after finishing a scan over the original or during the scan. A scan reading method also comprises the steps of: preparing a density histogram from the one-line image data in the original region; optionally obtaining the average density value of the variation rate thereof; detecting the top end and terminal of the original from that value; and calculating highlight and shadow densities from the density histograms after finishing the scan over the original by use of a scanner. Based on the methods of the present invention, it is therefore possible to automatically detect the edge of the original and perform a density auto-measurement at low costs with a high accuracy with the aid of a small capacity line memory without adding a multiplicity of sensors and incorporating a large capacity buffer memory.

Abstract: An electro-optical imaging system for efficiently determining a thin film layer thickness of, for example, a wafer over a full aperture. Non-uniformities in this layer thickness are obtained by measuring the reflectance characteristics for a full aperture of a wafer surface and comparing this measured reflectance data to reference reflectance data by using numerical iteration or by using a calibration wafer having known layer thicknesses. 
     To efficiently measure the reflectance characteristics of a wafer layer, a filtered white light source is used to produce a sequence of collimated monochromatic light beams at several different wavelengths. These collimated monochromatic beams are individually projected onto the entire surface of the wafer, and coherent interactions occur between this light as it is reflected from the physical boundaries in the wafer structure. As a result of these interactions an interference fringe pattern is formed on the surface of the wafer for each projected beam and, consequently, for each wavelength. A reflected image of each fringe pattern is projected onto a detector array of, for example, a charge coupled device (CCD) camera, where the full aperture of this image is then captured. The fringe pattern image is captured by digitizing pixels in the CCD camera detector array corresponding to the image present. A reflectance map of the entire wafer surface is generated from this captured fringe pattern image. Several reflectance maps are generated from each measured wafer to eliminate thickness ambiguities which may result from outer layers having phase thicknesses greater than 2π.
