Abstract: A method for operating an internal combustion engine of a vehicle traveling on the road, the method comprising of damping engine vibration with a damper coupled to the engine, and when said damping is reduced, preventing engine speed from falling below a threshold value, at least under selected operating conditions, to reduce degradation of the engine that would otherwise occur.

Abstract: An acoustic transmission connection, e.g. for a headset (13), comprises a sound tube (2) through which speech signals can be transmitted from a first end (16) to a transducer, e.g. a microphone, in a housing or a housing part (3) of the headset. In the sound tube (2) and in the housing part (3), means are provided for acoustic impedance matching and possibly means for achieving acoustic directivity.

Abstract: A memory device (1) for a processor (10) is disclosed. The memory device (1) and the processor (10) are integrated on a single chip. The memory device (1) comprises a first memory portion (2) for an initialization program and a second memory portion (3) for a user program. The first memory portion (2) can be written to and/or read from via a first group of data interfaces (16, 18), and the second memory portion (13) can be written to and/or read from via a second group(16, 17, 18). The first and/or second memory portions (3) contain memory blocks (4, 5, 6, 7) which are addressable block-by-block. A first memory block (4) comprises a protection control register (PCR) containing programmable enabling or disabling information for the individual data interfaces. An interrogation of the protection control register (PCR) takes place upon power-up.

Abstract: Headset for connection to a telephone apparatus, said headset comprising a capsule with a built-in receiver, and on which there is mounted a boom with a microphone. The headset is connected to a telephone apparatus by means of a wire with associated jack connection, and the headset has associated amplification and adjustment circuits for both the microphone and receiver, manual operating elements for the setting of said amplification and adjustment circuits, and switch elements for changeover depending partly on the type of microphone in the telephone apparatus and partly on the polarity of the telephone apparatus' microphone and receiver wires. The amplification and adjustment circuits are built into the headset capsule, so that the use of a separate connection box is avoided, and the manual operation elements are placed on the capsule. The switching elements consist of a multi-position switch, which is placed in the capsule in such a manner that it is accessible for operation.

Abstract: The invention relates to a method for the diagnosis of a sensor in connection with control of a combustion engine. The method includes feeding fuel under pressure (p) to the engine, detecting the pressure (p) by means of the sensor, and controlling the air/fuel mixture based on to the operating state of the engine. The invention involves an intentional modification of both the pressure (p) and injection time period (tinj) during which fuel is fed to the engine. The modifications are selected in such a way that substantially no change in the fuel flow (F) to the engine is obtained. A check is performed to determine if the modifications of the pressure (p) and injection time period (tinj) result in any unallowable deviation in the operating state of the engine. If so, an indication that the sensor is defective is provided. With the invention, an improved diagnosis method for checking the functioning of a fuel pressure sensor is provided.

Abstract: A diagnostic system (10) particularly though not exclusively for use in an engine management system is provided for generating a diagnostic trouble code (DTC) to indicate the operational status of a component or sub-system which is being evaluated by the diagnostic system. The diagnostic system includes a diagnostic function module (DF Module) (20, 20', 20") for each DTC or a group of related DTCs associated with a component or sub-system. The DF module including device (22) for executing an evaluation routine to evaluate the operational status of a component or sub-system to which the DTC of the specific DF module relates, and a diagnostic function scheduler (DF scheduler)(30) for determining which DF module may be allowed to execute an evaluation routine ant a particular time.

Abstract: The APO-1 cellular membrane antigen, an about 50 kDa antigen associated with cellular apoptosis, and purified cDNA encoding same is described. The antigen is expressed by numerous normal and malignant cells, including activated and malignant lymphoid cells. Also disclosed are antibodies which bind the antigen, and which induce growth inhibition and apoptosis.

Abstract: The system includes a plurality of individually selectable transmitter and receiver channels, a common controller and a common acquisition unit constructed to operate on the basis of parameters which are furnished to the controller and the unit as input signals. Some of the parameters are held in a memory and are withdrawn on the basis of test identification numbers to set up the acquisition unit. The acquisition unit has a transit time counter and two parallel operating looking window generators and several comparator stages, operating under utilization of such parameters. The data as acquired by a test, are accumulated and processed to determine new parameters, if necessary, and feeding them to the memory. The controller conducts the tests on the basis of sequencing the system through a group of test identification numbers, and provides also launch delay and receiving delays on the basis of externally, updatable parameters.

Abstract: An ultrasonic test system for inspection of structural material includes a test electronics for controlling a plurality of ultrasonic transmitter and receiver channels. This test electronics is operated by sequencing the system through the several channels, but the evaluating circuit is common to the receive channels. The duration of the test, timing of launching, timing of beginning receiving response signals, time and duration of looking windows for identifying and timing particular responses, and comparison data, all are operating and acquisition parameters for operating the electronics. These parameters are furnished from external sources and are programmable and exchangeable, e.g., from test to test. At least some of these parameters are updated on the basis of data as acquired during the test.

Abstract: Ultrasonic echo signals from the rear wall boundary are used to track looking windows for similar signals during a subsequent test cycle as well as for detection of flaw echos, with emphasis on a distinction between end of flaw detection and beginning first rear wall echo looking windows.
