Title: Device for the optical measurement of the turbidity of gases
IPC: G01N21/53
Filed: 1986-06-10
Abstract: A device for measuring the optical turbidity, i.e., the soot components in discharge gases of diesel engines, which is relatively simply constructed, operates safely and enables a simple handling even with differently structured measuring devices. This result is achieved in that a controller for controlling the light density of the measuring light beam is optically coupled with a light source. A sample and hold circuit is provided with the values of a measuring detector and the control detector fed to a sample and hold circuit in a time multiplex manner with the measuring values processed in a computer unit. Control values are fed to the light source by means of a control loop. In addition, the computer unit is capable of storing a plurality of measuring values or turbidity values and average value of the stored peak values, whereby the peak values are determined by a dynamic measuring of a defined number of measuring cycles. Moreover, a device is provided which feeds motor related parameter to the computer unit for triggering of measuring value determination and measuring value calculation.

Abstract: To avoid the overflow problem, in a graphics display system which employs 
matrix concatenation for coordinate transformation and matrix element 
precision equal to that inherent to the system, which can cause an 
out-of-bounds location of a data element, number translation shift 
factors are introduced for the last row of the matrix which when used to 
operate on matrix elements. This will maintain the elements within the 
physical boundaries of the graphics base by preventing overflow. The

Filed: 1987-05-20
Abstract: A semiconductor device (20) having selectively actuable links 
has a substrate (24) on which a doped region (22) has been 
formed. An amorphous region (38) of very low conductivity 
penetrates within the circuit element defined by the doped 
region (22). The amorphous region (38) is in contact with a 
metal layer (46) through a window in a dielectric layer (26), 
and there is thus no electrical connection between the circuit 
element (22) and the metal layer (46). The amorphous region 
(38) can be recrystallised and rendered conductive by the 
application thereto of an energy beam (50), such as green laser 
light, to thereby constitute a conductive link.  
     The invention enables high density packing of circuit elements 
on a semiconductor wafer.

IPC: H03K5/13
Filed: 1988-10-18
Abstract: A delay element for producing an output signal 
in response to a change in state of an input signal 
includes variable gain first and second amplifiers (A1, A2) 
and a delay buffer (12) having a fixed delay. The input 
signal is applied as input to the first amplifier (A1) 
and the delay buffer (12) while the output of the delay 
buffer (12) is applied as input to the second amplifier (A2). 
The outputs of the first and second amplifiers are 
summed to provide the output signal. When the gain 
of the first amplifier (A1) is high and the gain of the 
second amplifier is low, the output signal will 
respond to the change in state of the input signal 
with minimum delay. When the gain of the first 
amplifier (A1) is low and the gain of the second ampli­
fier (A2) is high, the output signal will respond to the 
change in state of the input signal with maximum 
delay. The delay in change of state of the output 
signal in response to a change of state in the 
input signal may be adjusted with high resolution 
to a time intermediate between the minimum and 
maximum delays by adjusting the gains of the first (A1) 
and second (A2) amplifiers.

Title: Cellular radiotelephone system with dropped call protection
IPC: H04W36/38
Filed: 1988-11-07
Abstract: An improved cellular telephone communication system 
is described having operational steps which prevent a 
call from being dropped due to a radiotelephone (130) not 
receiving a handoff instruction from its host base site 
(115). The system includes a switch controller (122) for 
determining that the radiotelephone requires a handoff 
from a first base site coverage area (110) to a second 
base site coverage area (112) and for communicating a 
handoff message to the associated first (115) and second 
base site equipment (119). The first base site equipment 
then transmits the handoff message to the radiotelephone. 
If the radiotelephone does not receive the message, it 
determines that the call has been lost, siezes a 
signalling channel from the second base site, and 
requests, via the second base site a call reconnection by 
transmitting a special message. The second base site 
then informs the radiotelephone of the handoff 
instruction and the handoff is completed with a 
successful reconnection of the call.
