  • Patent number: 5790198
    Abstract: Television schedule information transmission and utilization systems (50A-50D) transmit TV schedule data and associated network control messages provided by computer (54) as packets via the Video Blanking Interval (VBI) lines in the TV signal from various television program providers (51). This data is acquired by regional data processing systems and forwarded by the regional data processing systems to subscriber units (52) and used to construct an internal database. This internal database can be accessed by the subscriber unit (52) to display a TV schedule for the channels that are received by the user's TV.
    Type: Grant

  • Patent number: 5099090
    Abstract: An apparatus and method are disclosed for preparing electrically conductive traces on a circuit board using an additive technology. The traces are directly written in a serial process with each trace being able to be individually insulated. The apparatus includes an extrusion element for extruding a first material and a stage. The stage is for holding the extrusion element and the circuit board in relative proximity and for producing relative motion between the extrusion element and the circuit board in order to extrude the first material onto the surface of the circuit board along preselected paths to produce the electrically conductive traces. According to the method of invention, a first polymerizable material is extruded onto a circuit substrate support along preselected paths to form traces, and the first polymerizable material is polymerized, the first polymerizable material being conductive after polymerization.
