Title: Arrangement for testing integrated circuits
IPC: G01R31/28
Filed: 1988-01-13
Abstract: The invention relates to an arrangement for testing integrated circuits for sensitivity to electrostatic discharges at the connecting pins with the aid of a high-voltage discharge with all possible combinations of in each case two different connecting pins of an integrated circuit and measuring the input characteristics of these connecting pins before and after the discharge process. In previous test arrangements, the chip terminals were mechanically contacted. The test sequence was therefore not suitable for automation. For this purpose, the invention provides that the connecting pins of the respective test chip (1) are connected to an adaptor (2) which, in turn, is connected to a relay matrix (3) for transmitting the high-voltage discharge of a relay matrix (4) for applying a logic level "1" and to a relay matrix (5) for applying a logic level "0" or earth level. The three relay matrices are selected by a processor (8) via a relay matrix decoder (6) and a relay matrix control (7). The processor is connected at the same time to a relay control (9) which operates other relay sets (10, 11 and 12) for switching the supply voltages, the high-voltage discharge and characteristics measuring device and the logic levels. <IMAGE>

IPC: F02C9/28
Filed: 1988-06-21
Abstract: An integrated engine control-autothrottle control system for con­
trolling changes in the thrust of a jet aircraft engine during transients (i.e., 
changes in speed) in a manner that prevents throttle lead and overshoot (i.e., 
exceeds the response capability of the engine) is disclosed. The system uses the 
engine control to continuously monitor current fuel flow (WF), burner pressure 
(PB), high rotor speed (N2) and engine thrust (EPR), manipulates the signals and 
produces limiting fuel flow transient error (WFPBERR) and rotor speed transient 
error (N2DOTERR) signals for both acceleration and deceleration. The lower 
parameter transient error signal is selected as the controlling limit signal during 
acceleration and the higher parameter transient error signal is selected as the 
controlling limit signal during deceleration. The controlling limit signals are 
used to produce limiting throttle lever angle rate of change signals -- +TRADOT 
for acceleration and -TRADOT for deceleration. The throttle lever angle rate 
of change signals denote the maximum rate at which the throttle can be 
advanced (+TRADOT) or retarded (-TRADOT) without exceeding the response 
capabilities of the engines. The TRADOT signals are transmitted to the 
autothrottle and used to limit fuel flow changes so that the response capability 
of the aircraft is not exceeded.

Abstract: Apparatus for analyzing the composition of metal

of metal particles each time it is filled, and has a profile 
that diverts any excess particles away from the cup. A

emissions spectrometer (59) receives the dissolved sample and is 
employed to produce emission spectra from the dissolved 
sample. The spectra is compared to emission spectra 
produced by a known amount of a known alloy of the same

Title: Digital filter
IPC: H03H17/06
Filed: 1989-11-21
Abstract: A digital filter performs a predetermined arithmetic 
operation on input digital data inputted thereto in time-series 
manner by the predetermined first sampling period to thereby 
generate output digital data corresponding to a second sampling 
frequency which is N (where N denotes an integral number) times 
larger than the predetermined first sampling frequency. This 
digital filter provides a synchronizing signal generating 
circuit (20) and an operation control circuit (18). The 
synchronizing signal generating circuit detects the 
predetermined first sampling period of the input digital data 
to thereby generate a synchronizing signal having the second 
sampling frequency. The operation control circuit is activated 
by its internal clock which is asynchronous with the input 
digital data. This operation control circuit starts to perform 
its operation processes when the synchronizing signal is 
supplied thereto, thereafter it terminates the operation 
processes when a predetermined step number is completed.

Title: Self-corrected assay device and method
IPC: C12Q1/60
Filed: 1989-08-30
Abstract: An assay device (10) and method for determining the 
concentration of an analyte in a fluid sample. The device 
includes at least two reaction zones (18, 20) which receive 
a fluid sample, and each reaction zone includes the same 
signal-generating components for converting an intermediate 
reaction product to a detectable reaction product. Where 
the intermediate product is H₂O₂, the signal-generating 
components may further include a trapping compound which 
competes with the substrate of the detectable signal 
product, to produce a silent reaction product, 
proportionately reducing the amount of detectable reaction 
product produced. In an embodiment of the device containing 
two reaction zones, the signal generated in the second zone 
is used to construct a standard curve which corrects for 
reduced-signal effects related to loss of reagent activity 
and linear inhibition effects. In an embodiment containing 
three reaction zones, the signal products generated in the 
second and third zones are used to construct a two-point 
standard curve which corrects for reduced-signal effects 
related loss of reagent activity and non-linear inhibition 
effects. The signal value from the first zone in each 
embodiment is plotted on the standard curve, to determine a 
corrected analyte concentration value.
