Abstract: ABSTRACT           A link quality analyzer measures the link quality between a calling station and a called station by continuously transmitting a plurality of signal tones.  The called station receives the plurality of transmitting tones and samples them.  A power spectrum is obtained of the received tones.  From the statistics of the power spectrum the parameters of signal-to-noise ratio, multipath delay spread, Doppler frequency spread, frequency offset statistics, frequency-amplitude correlation, average amplitude response versus frequency, signal fading statistics, harmonic and intermodulation distortions, RMS-to-mean signal ratio, noise profile, and various noise statistics are determined.  The power spectrum of the plurality of tones is measured through the use of digital sampling techniques and digital fast Fourier transform techniques that are implemented through microprocessor-level technology.

Abstract: CONTROL CIRCUIT FOR ROAD AND ENGINE SPEED GOVERNOR           ABSTRACT       An electronic control circuit is disclosed for an engine and load speed governor of the type comprising an overriding throttle closing device.  The control circuit comprises engine speed signal generating circuit and a load speed generating circuit to provide electrical speed signals to the input of a microprocessor.  The microprocessor develops motor control signals for a reversible electric motor which drives the actuator for the throttle limiting device.  The motor control signals for operation in the close throttle direction and the open throttle direction are developed at different outputs of the micro-processor and applied to respective inputs of a motor driver circuit.  The motor control signal produced by the microprocessor are time modulated, either pulse rate or pulse width, in accordance with the operating conditions of the engine or load to provide operation of the motor at precise-ly controlled slow speeds.  Unmodulated motor con-trol signals are also produced by the microproces-sor under certain operating conditions to provide operation of the motor at full speed.

Abstract: ABSTRACT OF THE DISCLOSURE            A propellant is mixed with unsaturated polyester inside a first space (A) at a first pressure, for example at the atmospheric pressure. The polyester is then sprayed on the wole or parts of an open or exposed mould which is applied in a low-pressure chamber having a powerful negative pressure of 60-95% vacuum. In order to spray a first layer, polyester having a first amount of propellant is sprayed on the mould. At the initiation the propellant causes a powerful foaming effect at which bubbles are created and/or expanded in the polyester.          In order to spray a second layer, which can be applied before or after the first layer, polyester having a second amount of propellant, or is without propellant, is sprayed on the mould, which causes fewer bubbles or no bubbles at all. The resulting polyester which comprises formed and expanded bubbles is bound (is allowed to take rigid shape/is polymerized) by the use of a short tack-free time in the low pressure, said short time being preferably 5-10 minutes.

Abstract: Abstract of the Disclosure A mechanism for continually testing a floating point accelerator processor (FPAP) element or other processor element in a suitable multiprocessor system.  At least two processors, such as an instruction execution processor (EU) and a FPAP, are connected to a common input bus to concurrently receive the same information (opcodes and operands).  Both the EU and the FPAP decode the opcodes. When the FPAP decodes an opcode for an operation to be performed by the EU, the FPAP, instead of remaining idle while the EU operates, executes a diagnostic operation. The FPAP selects the particular diagnostic operation to perform in each instance from among a multiplicity of available diagnostic operations. The selection of a diagnostic operation is dependent on the instruction to be executed by the EU; in order to not slow down the overall execution rate of the system, a diagnostic operation is chosen whose execution time is matched to the execution time of the instruction being performed by the EU; that is, a diagnostic operation is selected such that the FPAP will finish the operation before the EU will finish executing its instruction. Operand data supplied to the EU on the input bus is used by the diagnostic operations, to add a degree of randomness to the test signals and permit detection of bits forced to a steady value of zero or one.  For some diagnostic operations, one or more variables may be obtained from general purpose registers.     The EU is not notified of the detection of an FPAP self-diagnostic error until the next operation which is to be performed by the FPAP, at which time such operation may be aborted or allowed to go to completion, depending on whether or not the source of the error will affect that operation.     Thus both the data paths and the control logic of the FPAP are checked during the execution of every non-floating point instruction.  System response is not slowed, only an insignificant marginal cost is added and the diagnostic system is completely transparent to the programmer.

The driver tip has a recessed face which defines between the face and the side walls of the tip   cutting margins which act as a scraping device  as the tip is in inserted into the socket to thereby scrape the side walls of the socket clean.  This allows proper mating penetration of the tip into the socket and hence mating of the tip with the socket whereby the driver may then be turned and the screw rotated so that the screw may be easily removed. The profile features of the tip allow cleaning of the socket and tip penetration into the socket by one single and continuous motion.
