Abstract: In general, in one aspect, the invention relates to a computer readable medium including software instructions for performing a method, the method including receiving, by a content server, a first request from a client for an application content file, wherein the application content file is associated with a first Java network launch protocol (JNLP) file, providing, in response to the first request, the application content file; receiving, from the client, a second request to edit the application content file, providing, in response to the second request, an application designer tool to the client; receiving, from the client, an altered application content file generated using the application designer tool, generating a second JNLP file associated with the altered application content file, and providing, to a webserver, the second JNLP file.

Abstract: Techniques for using imaging information computed from examining a scanner signal are described. When one or more objects passes within a field of view of a scanner, scan patterns emerging from one or more scanner windows and reflected from the objects back into the scanner windows produce one or more scanner signals. The scanner signals are processed to obtain beam position and beam length information to improve the accuracy of bar code decoding and to compute imaging information for objects within the field of view of the scanner. The imaging information for the objects is compared with bar code information for the objects. The expected number, size and shapes of objects indicated by the bar code information is compared with the actual number, size and shapes of objects in order to determine if valid scans occurred or if missed, double or otherwise erroneous scans occurred.
