Abstract: The invention relates to an improvement in methods for reading bar codes, making it possible to read the codes even under difficult conditions: irregular print, dirty background, weak contrast, broken bars, etc. 
<??>Instead of being content with detecting light reflection or absorption peaks when a detector passes in front of the code, the exceeding of a threshold indicating the presence of a bar, this is what is done: a matrix image of black and white pixels is established; the sum Tj of the black pixels of each column is counted in order to establish a curve Tj depending on the abscissa j of the columns; a threshold SDA is established for Tj, below which the columns do not in principle contain a segment of bar of the bar code; blocks of columns exceeding the threshold SDA are delimited, and all the other columns of the image are eliminated; then a shape recognition is performed on the remaining blocks in order to establish whether the block actually corresponds to a bar or not. The value SDA is established through a recurrence calculation involving the ratio between surfaces Sinf and Ssup above and below the threshold SDA in the curve Tj = f(j).

Abstract: In an image sensing apparatus such as a video camera, an evaluating value for exposure control and determination of a gamma correction value is computed in response to a video signal obtained by an image sensing device for each of a plurality of sampling areas set on an image sensed picture. When an evaluating value exceeding an allowable range with respect to a predetermined reference value is included in the evaluating values, it is determined that an abnormal luminance portion exists in the corresponding sampling area, so that weighting of the evaluating value is decreased, whereby the effect of such an area on exposure adjustment is restrained. In addition, the picture contrast is computed from the ratio of the maximum value to the minimum value of the evaluating values, whereby the most suitable gamma correction value is determined based on this picture contrast.

Abstract: Optically active 1,3-dioxolane derivates of the general formula <IMAGE> which carry a mesogenic radical in the 4-position are suitable as dopes in - in particular ferroelectric - liquid-crystal mixtures. The symbols in the general formula have the following meanings: R<1> has a structure analogous to the moiety of the general formula on the right of X or is an alkyl or alkylene radical, which may be substituted, R<2>, R<3> and R<4> are H or alkyl (R<4> is alternatively alkenyl), which may also be substituted [R<2> and R<3>, together with the C(2) of the dioxolane ring, may alternatively be cycloaliphatic or keto groups], j, l and n are zero, 1 or 2, and k and m are zero or 1, with the proviso that n is zero if k is zero, m is zero if n is zero, and 1 </= j + l + n </= 3, -A<1>, -A<2> and -A<3> are an aromatic, heterocyclic or aliphatic ring system, -M<1> and -M<2> are -CO-O, -O-CO, -CH2CH2, -CH=CH, -CH2O, -OCH2 or -C IDENTICAL C and  X is O, S or O-CO-O. The particular advantage of the compounds of the general formula (I) is that they are able to induce a high twisting power in the cholesteric phase, but without significantly affecting the magnitude of the spontaneous polarisation already present in the mixture in the smectic C<*> phase. They are therefore suitable for pitch compensation, in particular for ferroelectric liquid-crystal mixtures.

Title: Variable beamwidth stage light.
Inventor: RICHARDSON BRIAN E
IPC: F21V14/04
Filed: 1988-12-01
Abstract: A variable beamwidth stage light relying upon an axially movable reflector for changes in beamwidth. The reflector has a plurality of radially outwardly and axially forwardly extending leaves in side-by-side relation to define a bowl-shaped reflector surface. A stationary support flange is in frictional contact with the radially outward surface of each leaf. The reflector leaves are sandwiched between a base member and a ring member at the base of the reflector. A motor driven lead screw is attached to the base member to cause axial movement of the reflector relative to the support flange. The reflector defines a first and a second focal point along the axis of the reflector. A light source is fixed at the first focal point, which remains substantially fixed relative to the base member. Contact of the support flange with the reflector leaves causes the diameter of the reflector leaves to vary as the base member is moved, thereby causing displacement of the second focal point and variation of the bandwidth issuing from the reflector.

IPC: A47J31/057

Abstract: In a known coffee machine (1) for brewing hot beverages, the leached aroma carrier (23) is dried by steam which has to be generated in a steam vessel which is to be provided independently of the brewing water vessel. However, steam vessels operate under increased pressure, with the result that extensive safety precautions are necessary. This expenditure is only of value if the steam preparer can also be used for other purposes, for example for preparing cappuccino. To simplify the design, an instant heater (11) is proposed for drying the leached aroma carrier, which heater continues to heat a residual quantity of hot water after completion of the brewing operation, with the result that said hot water is forced through the aroma carrier and dries it in the process.
