摘要： A machine state virtualizer is an apparatus for controlling an electronic device having a switch matrix of X-lines and Y-lines (sometimes referred to as crosspoint switches) with a microcomputer. The device includes a plurality of switches which interconnect specified X-lines and Y-lines of the electrical device. A microcomputer references a machine state virtualization map and outputs data corresponding to a desired machine state. The output data is then decoded and used to control the plurality of switches so as to virtualize the desired machine state of the electronic device. The microcomputer utilizes sequences and rules for implementing a defined device control objective.

摘要： The present invention relates to a fuel pump control system for controlling fuel dispensers through a PC-based POS terminal. The system includes a printed circuit board which can be inserted in an expansion slot in the PC for controlling the fuel dispensers. The system uses a microprocessor with read-only-memory and read-and-write-memory. A series of commands are stored in the ROM for controlling the dispensers during the fueling process. A configuration circuit translates and configures the communication protocol of the pump control system and the communication protocol of the dispensers allowing them to interact. Response data from the dispenser during the fueling process is stored in the RAM. The pump control system is interfaced to the POS application software in the POS. In a preferred embodiment, the flow of data between the microprocessor in the pump controller and the microprocessor in the PC-based POS is controlled by a terminate-stay-resident driver. The system allows the POS application software program to integrate pump control with other features as cash register, card authorization, inventory control, and related. The present invention is particularly well suited for use in open-platform PC-based POS systems, can accommodate customized POS application programs.

摘要： Apparatus and method are provided for intelligently controlling an electrical power distributor for a personal computer, its peripherals, and other devices. The apparatus includes a parallel interface; single-chip microcomputer; plurality of relays; power source connector; and plurality of electrical outlets. The parallel interface can be removably connected through a parallel cable to a parallel port of a personal computer. The single-chip microcomputer has a clock to keep time independent of the personal computer. In response to programming instructions from the personal computer, the single-chip microcomputer controls the relays to selectively connect and disconnect the power lead connector to the electrical outlets of the distributor. Communicating with the distributor is made user friendly by including a software prorgram for the personal computer that translates simple commands from the user into commands sent through the parallel port of the personal computer to the distributor. The distributor can share the parallel port of the personal computer with another peripheral device, such as a printer, by use of a split-Y parallel cable or similar split cable or connector. The distributor reacts only to particular data transmitted on the split-Y parallel cable and ignores other data. A preferred embodiment of the distributor also includes a phone ring interface for detecting and responding to telephone ring signals. The single-chip microcomputer can be programmed by the personal computer to respond to one or more preselected sequences of one or more phone ring signals.
