Title: Method for resource allocation in a radio system
Inventor: GUNMAR KRISTER
IPC: H04W16/18
Filed: 1990-02-22
Abstract: (57) Abstract The present invention relates to a method for resource allocation in a radio system comprising base stations with respective coverage areas and mobile units. The interaction between the stations in the system is defined with the aid of measured and/or calculated field strengths from all base stations on relevant traffic routes in the geographic area of the radio system, preferably in the form of an exclusion matrix. An allocating matrix is formed by compressing the exclusion matrix by means of an allocating algorithm. The algorithm utilizes figures of merit which are on the one hand calculated by mathematical/logical means to form possible combinations of stations and utilizes on the other hand a random technique for selecting one of these combinations. The algorithm is iterated a number of times and different allocations are obtained thanks to the random technique. The best one of the allocations from any point of view is selected.

Title: Retroreflective sheet
Inventor: ROWLAND WILLIAM P
IPC: G09F13/04
Filed: 1992-03-31
Abstract: A retroflective material retroreflects a white coloration for light beams impinging thereon at night and appears to have the coloration of the underlying support in daylight.  This material utilizes  retroreflective  sheeting having closely spaced microretroreflective formations on one surface, and a transparent adhesive in a pattern over that surface so as to leave the predominant portion of the surface  free from adhesive.   A transparent backing element is adhered to the sheeting by the adhesive, and it extends in a plane generally above the  formations  to  leave  the  formations  in  the predominant surface area exposed to the atmosphere thereabout. Light rays entering the the other surface of the sheeting and impinging upon the prisms of the predominant surface area are retroreflected by the interface with the atmosphere, and those impinging upon the formations in the area coated by the adhesive pass through the adhesive and the backing for reflection and refraction from the underlying surface, thereby evidencing its color in daylight.
