Patent number: 4422148Abstract: An electronic postal meter has a control unit, an accounting unit and a printing unit, each incorporating a CPU having a separate crystal controlled clock. Communication between the units is serial character asynchronous, bit synchronous, in message form, with the bits of the messages being timed in accordance with a given schedule for synchronous control. The messages themselves, upon receipt by a receiver, are returned bit by bit to the transmitter, for checking, whereupon the transmitter sends a no-error pulse upon successful comparison of the transmitted message and the message received from the receiver. All control and data signals utilize the same pair of conductors in each direction with precisely defined timing for control.Type: GrantFiled: May 6, 1981Date of Patent: December 20, 1983Assignee: Pitney Bowes Inc.Inventors: John H. Soderberg, Alton B. Eckert, Robert B. McFiggans

Patent number: 4377739Abstract: A power control method and apparatus maintains a constant average power at an electrical load, such as a fuser in an electrophotocopy machine. A power monitor measures the average power delivered to the load and compares the measured power to a predetermined power. A digital network receives an input signal from the power monitor and controls the coupling of power from an ac source to the load. When load power is less than a predetermined level, the digital network couples every half cycle of the ac power source to the load. When the load power is equal to or greater than the predetermined power, the digital network couples every third ac half cycle to the load. As a result, only half cycles of sequentially opposite polarity are coupled to the load.Type: GrantFiled: July 6, 1979Date of Patent: March 22, 1983Assignee: Pitney Bowes Inc.Inventors: Alton B. Eckert, Jr., Wayne W. Pritchett

Patent number: 4376981Abstract: A system for automatically setting a postage meter as a function of package weight and destination includes a scale mechanism for generating weight-representing signals. The package postage can be established by converting the destination zip code to a destination zone. The destination zone used in retrieving a minimum postage and incremental postage amounts is applicable for that zone from data storage. The weight-representing signal is successively decremented and the postage amounts synchronously incremented until a signal checking circuit establishes that the decremented weight-representing signal is equal to zero.Type: GrantFiled: July 3, 1979Date of Patent: March 15, 1983Assignee: Pitney Bowes Inc.Inventors: Frank T.
