Abstract: A diagnostic system for control apparatus of a motor vehicle equipped with self-diagnostic functions in which the control apparatus are connected with each other by way of a diagnostic bus and a defect lamp line. Diagnostic functions can be initiated by way of a key or momentary switch in an initialization line of the diagnostic bus whereby the diagnostic results can be read out at a defect lamp connected to the defect lamp line by way of flashing code word. The defect output thereby takes place strictly sequentially, defect-by-defect and control apparatus by control apparatus.

Abstract: ABSGAM is a computer model developed to predict the maximum sortie generation capability of aircraft operating from a typical USAF air base. The model allows the user to easily change input parameters to evaluate their effect on: (1) aircraft sortie rates, (2) cumulative sorties generated, (3) payload launched, and (4) material personnel required to support the air base operation. ABSGAM simulates (1) an air-base-attack and recovery, (2) reduced payload operations, (3) reduced maintenance capability, (4) extended turn-around time, and (5) aircraft attrition (both air and ground). Program input has been minimized for ease of use. Program output is available in tabular and graphical form. This model was developed as part of a technology assessment.

Abstract: The present invention is directed to a method and apparatus for controlling an automatic transmission. A selector selects a first speed change range or a second speed change range in which the first and second speed change ranges effect speed changes at different points as a function of vehicle operating conditions. A microprocessor having a memory stores predetermined speed change patterns for the first and second speed change ranges and sensors are coupled to the microprocessor for sensing at least two vehicle operating conditions. The microprocessor controls the operation of the transmission in accordance with the vehicle operating conditions and the state of the selector. A selectively operable inhibiting device inhibits the transmission from operating in the maximum speed stage when the transmission is operating in the second speed change range.

Abstract: A high accuracy power meter capable of measuring power supplied or consumed in multiple phases of a distribution system is fabricated as an integrated circuit. Voltage and current sensing transducers coupled to the power meter provide input signals having a potential proportional to the voltage and current in the distribution system. A low charge injection pulse width amplitude multiplier using a digitally-synthesized triangular wave is provided for each phase. Each multiplier receives the input signals and provides an output signal having a current proportional to the product of voltage and current in that phase of the distribution system.Charge from the multiplier output currents for all phases is accumulated in a capacitor connected across an autozeroing amplifier, which corrects for its own offset voltage. The amplifier output controls a switch connected between a reference potential and the capacitor.

Abstract: The invention is a method of assisting lumber grading using an electro-optical scanning system. A first critical determination is determination of pith position of the log from which the lumber was cut, relative to the scanned faces. This then indicates knot orientation. With knot orientation known, knot size and position data also determined by the scanning system can be used to accurately estimate cross sectional area of the knots. From this point a tentative lumber grade can readily be assigned. Pith position is indicated by a number of factors including wane, knot counts on each of the faces and the presence or absences of spiky faces. A preferred form the scanner is one which measures localized wood fiber angles relative to three orthogonal axes. These fiber angle measurements reveal grain slope disturbances on the lumber which are indicative of many types of defects including knots. The system has been used for grading lumber at speeds as high as 350 m/min. with considerable accuracy.

Abstract: A system and method for automatically controlling a vehicle speed to a desired cruising speed are disclosed in which an abrupt deceleration time for which the vehicle is abruptly decelerated to the vehicle speed at a time when an off operation of an acceleration switch in a cruise command switch group is carried out after an on operation of the acceleration switch to carry out a constant deceleration of the vehicle is calculated from the total duration of time for which the actuator is controlled so that the vehicle speed increases at a constant rate. Therefore, no need to adjust the abrupt deceleration time according to the individual vehicles in which the systems are mounted. In addition, since the actuator is rendered in the abrupt deceleration state within the appropriate duration of time, road conditions, or a speed range in which the vehicle cruises does not affect the performance of the system.
