Patent EP-0261850-A3 (EP)
IPC: B29C65/02
Filed: 1987-09-11
Abstract: In a method of manufacturing a fusion bonded joint between a 
fibre reinforced thermoplastic resin component having at least 30 
per cent of its volume comprised by reinforcing fibres (high fibre 
loaded) and another fibre reinforced thermoplastic resin component 
having more or less than 30 per cent of its volume comprised by 
reinforcing fibres, additional thermoplastic resin is incorporated 
at the joint interface prior to joining by fusion bonding.  
     The additional thermoplastic resin is preferably consolidated 
in those surfaces of the high fibre loaded component which are to be 
joined to other components before fusion bonding takes place.  
     A preferred method of fusion bonding is by ultrasonic 
welding.  
     A mesh comprising metal strands extending at least across the 
joint may be incorporated at the interface of a joint between two 
components to provide increased joint strength and electrical 
conductivity across the joint in the case of carbon fibre reinforced 
components.

Title: Logic redundancy circuit scheme
IPC: H03M7/00
Filed: 1988-09-27
Abstract: A logic redundancy circuit scheme, comprising a plurality of 
pairs of logic circuit groups, each logic circuit group in a 
given pair having a respective logic node and a respective 
power control line, with each logic circuit group in a given 
pair generating substantially the same logic function signal 
on its respective logic node as the other logic circuit 
group in the given pair generates on its respective logic 
node. The circuit scheme further includes a plurality of 
isolation circuits having respective output nodes, with a 
different isolation circuit connected to each different 
logic circuit group logic node. These isolation circuits 
are powered at all times and each operates to provide an 
output signal on its output node indicative of the signal on 
the logic node connected thereto, while isolating the 
connected logic node from nets connected to the isolation 
circuit output node. The circuit scheme also includes means 
for electrically connecting together for bidirectional 
communication the logic nodes for each pair of logic circuit 
groups, prior to the connection to the isolation circuit 
associated therewith, and switching means connected to each 
of the power control lines associated with the plurality of 
pairs of logic circuit groups for providing power to one and 
only one logic circuit group in each pair of logic circuit 
groups. The circuit scheme also includes means for 
controlling, through the electrically connecting means,the 
logic state at the isolation circuit output node of the 
logic circuit group in a given pair of logic circuit groups, 
which is not powered, to have the same logic state as the 
isolation circuit output node of the logic circuit group in 
the given pair of logic circuit groups which is powered by 
the switching means, so that both isolation circuit output 
nodes in the pair provide a correct logic signal.

Abstract: In the case where a prover A proves the validity 
of a pretender B to a verifier C, B receives an initial 
response x′ created by A, randomizes it with a random 
component and sends it as x″, and randomizes an inquiry β 
from C with the random component and sends it as β′ to A. 
A proves, for the received randomized inquiry β′, the 
validity of B by a secret key s randomized with a random 
number r and then sends it as a proved response z to B. B 
removes the random component from the proved response z 
and sends it as A's proof to C for verification. B keeps 
secret the procedures for randomizing the initial response 
x′ and the inquiry , thereby maintaining secret the 
correlation between A - B interactions (x′, β′, z) and B - 
C interactions (x″, β, z′).  
     In the case of proving the validity of a message 
m of a signature client B to the verifier C by attaching a 
signature of A to the message m, B receives an initial 
response x′ created by A and randomizes it with a random 
component to create a randomized response x″, creates a 
randomized inquiry β′ containing a random component by use 
of the randomized response x″ and the message m, and sends 
the randomized inquiry β′ to A. A proves, for the 
randomized inquiry β′, its validity by a secret key s 
randomized with a random number r and then sends it as a 
proved response z to B. B removes the random component 
from the proved response z to create a derandomized 
response z′, which is sent to C for verification.

Patent EP-0334546-A3 (EP)
Title: Thermal-ink-jet print system with drop detector for drive pulse optimization
IPC: B41J2/125
Filed: 1989-03-15
Abstract: A thermal ink jet printing system includes a drop detector (25) 
which is used in a feedback loop to optimize operational drive pulse 
parameters. By optimizing the drive pulse, drop velocity can be set 
within an optimal range above a inflection point in the transfer function 
of a print head drop generator. This provides near maximal drop velocity 
while minimizing heat dissipation at the heater resistors which would 
otherwise impair reliability and print head life. The drive circuitry 
includes a microcontroller (11) including a pulse controller (13), a test 
generator (23) and an algorithm function (21). During a maintenance 
procedure, for example, during start-up, the test generator (23) causes 
the pulse controller (13) to test each of many drop generators with a 
series of fixed-voltage rectangular pulses of digitally increasing pulse 
width. The pulse width at which a drop is first detected and the velocity 
of each drop detected is correlated with the width of the pulse which 
generated that drop. The algorithm function (21) calculates an individual 
operational pulse width for each drop generator, or alternatively, a 
common operational pulse width for all drop generators, from the test 
data so collected. The pulse parameter value set so determined is 
programmed into the pulse controller (13) and used during normal 
printing operation.

Title: Jfet analog switch with gate current control
IPC: H03K17/687
Filed: 1989-05-10
Abstract: An analog switching circuit may be implemented with MESFETs 
without forward biasing the switching device, and is applicable to 
JFET switches in general. Switching currents are provided from a 
nominal input line (20) which closely tracks the true analog input 
voltage, but is segregated therefrom. A current supply (E1) fed 
from the nominal input line (20) provides transient charging 
current to the gate of the switching transistor (M1) during the 
switching transition from OFF to ON states. Voltage setting 
devices (D1, R1, D2, R2) hold the gate and source of the 
enhancement-mode current supply (E1) at approximately the nominal 
supply voltage level when the switching transistor (M1) is ON, 
while a control section (D3, E3, D4, E4) holds the gate and source 
of the current supply device (E1) at a negative reference voltage 
level (V⁻) when the switching transistor (M1) is OFF. In either 
case, the current supply device (E1) is inhibited from delivering 
gate current to the switching transistor (M1) during steady state 
operation.
