Abstract: An electronic switched-output controller apparatus comprises a plurality of relays for providing a plurality of controlled switched outputs, the relays being selected from the group consisting of power relays, signal switching relays, dry contact closing relays and combinations thereof, each of the relays having a corresponding relay operating coil. A power section is configured for receiving AC line power and for providing internal operating DC voltage and is connected for providing line AC power to any power relays and thereby to corresponding outputs when the corresponding power relay coils are actuated, and for providing DC voltage to any signal switching relays and thereby to corresponding outputs when the corresponding switching signal relay coils are activated.

Abstract: A one time programmable (OTP) electronic switched-output controller apparatus comprises a plurality of switched-output relays which may be power relays, signal voltage relays, dry switching relays or any combination thereof. A power section receives AC line power and provides at least one internal operating DC voltage and provides line AC power to any power relays and to the related power outputs when the relay are actuated. An A-D converter provides DC voltage for internal operation and to any DC voltage relays. A one time programmable microcontroller, which has outputs connected to the relay coils, is programmed before installation in the switched-output controller apparatus to cause actuation of the relay coils in accordance with a preestablished operating protocol. The apparatus is shown connected for receiving RS232 signals and has an internal modem for receiving external signals over a telephone line. A relay enables switching between the RS232 and modem inputs.

Abstract: A process for making a radiation-reflecting record carrier, such as a video disc, is provided on which video and/or audio information is stored in an optically readable track in which first reflective areas alternate with second reflective areas, the two reflective areas having different effects on a reading beam in a playback machine so that the information recorded on the carrier may be recovered. The second reflective areas serve to direct the reading beam away from the path along which it is reflected by the first reflective areas. The process uses photographic techniques to form a master negative or positive, and to form record carrier replicas from the master.In the disclosed embodiment of the method and apparatus of this invention, the second reflective areas of replica carrier are formed by raised crystalline deposits of a material such as silicon which are chemically deposited in a selected, optically generated pattern on the replica carrier.

Abstract: A process for making a radiation-reflecting record carrier, such as a video disc, is provided on which video and/or audio information is stored in an optically readable track in which reflective areas alternate with non-reflective areas, the two areas having different effects on a reading beam in a playback machine so that the information recorded on the carrier may be recovered. The non-reflective areas are formed as apertures in the reflective areas and the underlying substrate is preferably translucent. The disclosed process uses photographic techniques to form a master negative or positive, and to form record carrier replicas from the master.In one disclosed embodiment of the method and apparatus of this invention, a two-sided recording medium comprises two transparent substrates, each of which supports a perforated metallic, reflecting layer. The two substrates are held together by a layer of adhesive disposed between the two reflecting layers.
