Patent EP-0200920-A3 (EP)
Title: Domestic electric range
IPC: F24C15/02
Filed: 1986-04-03
Abstract: An electric oven has a number of heating elements for heating the cooking chamber. A multi-position switch is arranged to couple power to all of the heating elements, such that the chamber can be used as an oven, or to only selected heating elements such that a grilling operation can be performed. However, when grilling it is best if the door of the cooking chamber is at least partially open so that air can circulate. The invention provides a mechanical linkage between the door and the switch such that if the switch is moved into its grill operating position, the door is automatically opened. In addition, if the door of the cooking chamber is closed, the switch is automatically moved into its oven operating position.

Title: Method and apparatus for generating size and orientation invariant shape features
IPC: G06V30/186
Filed: 1988-01-08
Abstract: A system extracts a set of size invariant, rotation 
invariant features from pixel data of a character and sends the 
set of features to a statistical decision tree to effectuate 
automatic recognition of a character. The set of extracted 
features includes a first group obtained by generating arrays 
representable as dimensions and other geometric qualities of six 
minimum bounding rectangles rotated about the character, 
including the distances between the center points of the rotated 
bounding rectangles. A second group of features is extracted by 
generating a group of arrays representing the perimeter pixel 
locations, radii lengths, and direction codes. The arrays of 
that group are "resampled" to generate corresponding 64 point 
arrays. The resampled arrays of direction codes is smoothed and 
incremental direction codes are computed and compared to 
preselected thresholds to obtain features that indicate prominent 
convex and concave portions of the character. A third group of 
features is extracted by dividing a circle bounding the character 
into eight rings and 24 slices and counting the number of 
character pixels contained in each ring and in each slice. 
Various Fourier transforms, autocorrelations, moment 
calculations, and sorting operations are performed on many of the 
aforementioned arrays to yield further size and orientation 
invariant features. The distance between the centroid of the 
 
 
largest hole of the character and the center of the character is 
computed. The ratios of the perimeters of first and second holes 
of the character to the outer perimeter are computed.

Title: A dual beam multichannel spectrophotometer with a unique logarithmic data converter
IPC: G01N21/27
Filed: 1989-02-14
Abstract: The present invention relates to an improved dual beam 
multichannel spectrophotomer employing a simple and novel 
optical system in combination with photodiode arrays and a 
unique logrithmic data converter to convert light signals to 
absorbance. In particular, the optical system utilizes optical 
elements in a novel arrangement to direct a pair of equivalent 
sample and reference beams in an essentially parallel formation 
respectively through a sample and reference cell and to focus 
and direct the emergent sample and reference beams to a single 
flat horizontally ruled grating which disperses each of the 
sample and reference beams respectively onto a pair of 
vertically disposed photodiode arrays whereby the light signals 
are converted into absorbance units (AU) by an unique 
logarithmic data converter. The spectrophotometer is highly 
accurate, has very low drift, less than 2 x 10⁻⁴ AU/°C, and 
very low noise, less than ±2 x 10⁻⁵AU. The dual beam 
multichannel spectrophotomer is particularly suitable for use 
in high pressure liquid chromatography to record the absorbance 
spectrum of the samples as they are being eluted from the 
chromatographic column.

Title: Method of marking a bottle with, and optically reading, readable codes
IPC: B41M5/24
Filed: 1989-07-10
Abstract: Described is a method for applying optically readable code markings (14) on the surface of bottles (10) made of plastic or glass by producing depressions in the surface by means of a laser (12) in such a way that the base of each code marking (14) is formed as a diffusing reflector. For automatically reading the code markings, a sensor (16) constructed from optical fibres having centrally arranged emission optical fibres and radially arranged receiving optical fibres is used. The sensor forms an angle of less than 90 DEG  with the bottle surface, so that light is reflected into the sensor only at points on the surface where code markings (14) are present. The code markings (14) are simple to apply and can be reliably read.
