Title: Handwriting recognition by character template
Inventor: COMERFORD LIAM D
IPC: G06F3/033
Filed: 1992-02-12
Abstract: ABSTRACT OF THE DISCLOSURE    A method for entry and recognition of elements from a set of symbols, involving a template of line segments displayed on an electronic writing surface.  A stylus is applied to the electronic writing surface so as to trace a desired symbol.  Computing means are used to "snap" the strokes  made  by  the  stylus  onto  the  corresponding template line segments.  Upon completion of a symbol, a code is made to represent the line segments and this code is used to  reference  entries  in  a data  structure  to identify the appropriate corresponding computer code.  If there is no match, the code for the line segments and a corresponding set of computer codes can be added to the table.    This   method   takes   advantage   of   natural handwriting  skills  and can be  used for  a variety of symbol sets.

Title: Process and device for transmitting video signals in a confined spaces
Inventor: CHARPENTIER DOMINIQUE
IPC: H04B7/10
Filed: 1990-12-07
Abstract: ABSTRACT OF THE DISCLOSURE         A UHF carrier signal modulated by a video signal, where the frequency and the format of a line synchronisation signal are known, is transmitted in a transmission region in a confined medium by a microwave link.  In a reception region, two signals are received along two angularly offset privileged axes, each is frequency-demodulated along identical processing channels, the existence in the signal emitted from one of the channels, the "starting channel", of a periodic signal with the line synchronisation frequency is checked and this signal is selected if the check proves positive.  If the periodic signal disappears, the test is applied to the other channel; if that check is positive, this other channel is selected until this periodic signal disappears, and so forth.  Such a process is especially applicable in tunnels.

Title: Multiangular color measuring apparatus
Inventor: BERG BERNARD J
IPC: G01J3/50
Filed: 1992-09-03
Abstract: MULTIANGULAR COLOR MEASURING APPARATUS          Abstract of the Disclosure A spectrophotometer apparatus (200) is adapted to provide spectral reflectance measurements of object, particularly optical characteristics of colored surfaces comprising metallic or pearlescent particles.  The apparatus (200) comprises a source light and a reflection optics assembly.  Signals representative of reflected light are analyzed and data is generated representative of the spectral response characteristics of the object sample.  The apparatus employs a plurality of fiber optic bundles for receiving light reflected from the object sample, with each of the fiber optic bundles being positioned at one of a corresponding plurality of fixed angles different from the angle of illumination by the source light.  Reflectance is measured at each angle by sequential switching such that light is impaired from being received from all but one of the plurality of multiple angles.  Light received from the fiber optic bundles is transferee to a single array of integral interference-filter/photodiode devices which modulate the light and determine the spectro characteristics thereof.  With the use of fiber optic devices, a single source of illumination and a single optical detector arrangement, the spectrophotometer apparatus is employed within an optimally small packaging configuration, and the apparatus can be maintained in a portable mode while maintaining relatively high accuracy and repeatability.
