Patent EP-0200022-A3 (EP)
IPC: G02B27/00
Filed: 1986-04-03
Abstract: An optical display system (10) employs a holographic 
optical element (20 or 22) that has a holographic fringe 
pattern which is coordinated with the phosphor emission 
peak (32) of a cathode ray tube (24) to eliminate perceptible 
variations in image brightness. The holographic optical 
element has a reflection characteristic (34) that defines two 
diffraction efficiency peaks (36 and 38) which are resolved by 
a low diffraction efficiency dip (40) that is interposed 
between them. The optimum wavelength spacing between 
the two diffraction efficiency peaks for a given wavelength 
spacing is determined by computing for all observer (28) 
head positions and look angles of concern the differences 
among the areas under the intergrated efficiency characteris­
tics (42) for the reflection characteristic (30) holographic 
optical element and the phosphor emission characteristic of 
the image-producing cathode ray tube. The optimum 
wavelength spacing is that which provides the desired 
variation among the computed difference values, which 
represent the display brightness uniformity. The center dip 
reflection characteristic increases the spectral bandwidth of 
the holographic optical element and thereby increases its 
reflectivity to promote good contrast with the use of a 
cathode ray tube operating at reduced beam current levels. 
When installed as a combiner (12 or 14) in a head-up display 
system (10) for aircraft, the holographic optical element 
superimposes the image on an outside scene without 
introducing significant discoloration of the scene.

Filed: 1986-03-13
Abstract: An analogue display has a circle (7) of electrically-energisable 
elements (70)that are selectively energised such as to 
represent time. A rotatable setting wheel (10) has a knurled edge (26) 
that projects from the display casing (1). A leaf 
spring (28) engages the knurled edge, the spring having a 
piezo-electric element (29) on its surface which produces pulses 
dependent on rotation and direction of rotation of the wheel. 
Different elements (70) are energised around the circle, as the 
wheel is rotated, according to the speed and direction of rotation. A 
second value, such as temperature, can be represented if 
each element (570) extends radially and is divided into separate sub 
elements (580). By energising different numbers of the 
sub elements (580) the apparent radial length of the element can be 
varied to represent the second value.

Title: Circuitry for complementing binary numbers
IPC: G06F7/508
Filed: 1986-07-08
Abstract: Circuitry for forming the twos complement or ones complement of N-bit binary numbers is described. The circuitry includes N stages each of which contains an exclusive NOR gate (300, 310, 320, 330, 340, 350). A first input terminal (B) of the exclusive NOR gate is coupled to receive one bit of the input value and a second input terminal (C) is coupled to receive the carry output signal from the previous stage. A logic one or logic zero is applied to the second input terminal (C) of the exclusive NOR gate (300) of the stage which processes the least significant bit of the binary word if the circuitry is to provide a twos complement or ones complement value respectively. The carry output signal for each stage is generated by ANDing (302, 312, 322, 334, 342) a logically inverted version of the input bit signal with the carry input signal applied to the stage. An application of the complementing circuitry in an absolute value circuit is also described. In this application, the carry input signal to each stage is ORed (612, 622, 632, 642, 652) with a logically inverted version of the sign bit of the input value and the result is applied to the second input terminal (C) of the exclusive NOR gate. This circuitry complements only negative values, passing positive values unchanged.

Filed: 1986-09-05
Abstract: The Applicant has discovered a correlation between 
photography, the laser mechanism, and SERS. It appears that 
all three effects or phenomena of photography, laser and 
SERS, originate from a similar mechanism, namely the am­
plifying factor comes from Einstein coefficients and subse­
quent description of inverse population - these being the 
essential building blocks for the aforementioned three phe­
nomena. Accordingly, one aspect of the invention is to utilize 
the principles of photography in connection with SERS. 
Another aspect is to utilize the principles of photography in 
connection with lasers. A still further object is to employ all 
three fields to achieve the lasing and laser effects described in 
greater detail in the specification.

Title: A method of detection of infection by testing of body fluid mucopolysacharide degrading enzymes
IPC: C12Q1/14
Filed: 1987-08-10
Abstract: An in vitro method of diagnosing viral and bacterial infections for use in human and veterinary medicine. The method is based on the appearance of mucopolysaccharide degrading enzymes (MPDE) in body fluids in consequence of an infection. Use is made of the capability of MPDE to degrade certain substrates for visual detection based on a color reaction with either intact MPDE or degradation product thereof. A viral infection gives rise to the formation of MPDE by the subject's body and in consequence the amount of indegenous is increased in such body fluids in which it also existed normally or is formed in body fluids in which it does not exist normally. In case of non-viral infections, the pathogens geneate their own MPDE which is different from the indegenous one and use can be made of this feature for distinguishing between viral and other infections. It is also possible to differentiate between different viral and different non-viral infections with the aid of charts of color patterns. For the detection of non-viral diseases, a growth medium is preferably incorporated in the matrix. There are also provided matrices and kits for the performance of the method.
