Title: Engine diagnostic apparatus
Inventor: MADDOCK JAMES B
IPC: F02B77/08
Filed: 1990-08-23
Abstract: Dynamic engine diagnostic devices are useful for detecting engine faults such as a misfiring cylinder during normal engine operation. Identification of the particular cylinder having the fault enables repairs to be made more efficiently. In the subject application, an apparatus (10) is provided for detecting malfunctions in individual cylinders of an internal combustion engine (12) having a rotating member (14) driven by a plurality of cylinders. The apparatus (10) includes a sensor (16) for measuring the time between successive angular positions as the member (14) rotates through at least one engine cycle and producing a plurality of period signals responsive respectively to the measured time intervals.  Each engine cylinder has an equal number of the angular positions associated therewith, and the number makes one rotation per engine cycle. A deviation circuit (28) receives the period signals and produces a deviation signal for each engine cylinder. each deviation signal is responsive to a difference between period signals of a respective cylinder. An averaging circuit (26) receives the deviation signals and produces an average signal responsive to an average of the deviation signals. A comparator (28) receives the deviation and average signals, compares each deviation signal to the average signal, and produces respective fault signals in response to individual deviation signals differing from the average by more than a first threshold.

Title: Synchronous digital signal to asynchronous digital signal desynchronizer
Inventor: BERNARDY EDMOND
IPC: H04J3/00
Filed: 1992-03-25
Abstract: Improved jitter performance is realized in a desynchronizer for obtaining an asynchronous signal, e.g., a Conference of European Posts and Telecommunications (CEPT)-4 signal, from a received synchronous signal, e.g., a Synchronous DigitalHierarchy (SDH) Synchronous Transport Module (STM)-1 signal. The improved jitterperformance results from employing a unique gap generator which causes gaps in areceived data signal to be spread regularly in time, and allows for almost continuous control by numerical techniques of the phase of a smooth output clock being generated. Phase control is obtained by employing a filtered version of the difference between the actual number of data bits in the received digital signal and the expected nominal number.

Title: Detent mechanism for controlling position of rotatable die
Inventor: GOUVEIA DAVID P
IPC: H01R43/042
Filed: 1992-10-02
Abstract: ABSTRACT OF THE DISCLOSURE A crimping tool comprises a pair of handles, crimping jaws,  dies,  and/or die nests, positioned at one end of the handles and in alignment with each other to receive a connector therebetween, a linkage extending between the handles and joining same together such that one handle pivots relative to the other and forces the jaws, dies, and/or die nests toward each other. A rotatable die wheel, with dies, of different sizes and shapes, is located at the forward end of one handle, in alignment with the working surface of a crimping jaw secured to the forward end of a second handle.  The die wheel has a plurality of passages extending transversely therethrough.  A chamber is formed in one of the handles, and a ball is placed therein.  A strap, formed of spring steel, is secured to one of the handles and exerts a biasing force upon the ball.  When the die wheel is indexed to place a particular die in operative positions the strap forces the ball to project  into one of the passageways,  thereby functioning as a detent to retain the die wheel in its indexed position.

Filed: 1993-03-05
Abstract: A   terminal   adapter   interfaces   between   a   Data Terminating Equipment (DTE) and either a Frame Relay (FR) or a    Switched    Multimegabit    Data    Service    (SMDS) telecommunications network so that the type of network over which the DTE is communicating is transparent to the DTE.
