Abstract: Provided are a computer program product, system, and method for training and using a vector encoder to determine vectors for sub-images of text in an image to subject to optical character recognition. A vector encoder is trained to encode images representing text into vectors in a vector space. Vectors of images representing similar text have a high degree of cohesion in the vector space. Vectors of images representing dissimilar text have a low degree of cohesion in the vector space. An input image is processed to determine sub-images of the input image that bound text represented in the input image. The sub-images are inputted to the vector encoder to output sub-image vectors. The vector encoder generates a search vector for search text. Optical character recognition is applied to at least one region of the input image including the sub-images having sub-image vectors matching the search vector.

Once the user device is out of range, the active beam is transitioned back to an inactive beam. An inactivity timer is used to detect an idle active cell that should be transitioned to an inactive cell.

By adopting the technical scheme, no additional decoupling structure needs to be introduced, and lower coupling can be realized in a wider working frequency band.
