The present invention discloses oxindole compounds and a single step, one pot reaction for the synthesis of oxindole derivates via a solvent free Passerini reaction of isocyanides, isatins and carboxylic acids. At least one adjustable threaded member has a contact end in contact with a rear surface of the first plate and a threaded outer surface in threaded engagement with a threaded bore of the second plate. During the translation process, a database of translated foreign code is populated and thereafter a software layer checks for correspondence between the foreign code and binary code stored in the database. Each identified information update can be stored with metadata indicating respective tag associations such that information updates are capable of being sorted and displayed on a display device. The users of NFC enabled devices may have little or minimal interactions except that one or more users may bring the devices within range so that the NFCs may initiate the pairing between the devices. The patch panel is adapted to measure a resistance associated with each port via the system wire.
