A tuner for television broadcast receiver comprising a plurality of annular patterns made with a conductive material and arranged concentrically in groups, and grouped contact strips arranged to face said annular patterns and to be able to contact these annular patterns, respectively, and being operative so that either one of the grouped annular patterns and the grouped contact strips is rotated in accordance with the broadcast channel selecting operation and that all of said channels may be selected automatically in accordance with a binary code formed by the combinations of contact and non-contact state between the respective annular patterns and the respective contact strips. This tuner for television broadcast receiver is simple in structure and easy to construct.

A utility data gathering system is disclosed as comprising a register including a series of index members coupled to a meter mechanism. Each index member includes a plurality of contacts and a switch arm moveable with its index member. The meter mechanism is responsive to utility consumption for moving the index members to positions indicative of the utility consumed, whereby each switch arm completes in normal operation a circuit with just one of its plurality of contacts dependent upon the position of its index member. A digital computer is programmed for performing first and second scans of each contact of each index member to obtain corresponding first and second sets of data indicative of a completed circuit through the switch arm and contacts of each index member. The completed circuit data obtained from each of the first and second scans are compared and if the circuit data of the first and second scans are different, an alarm manifestation is generated.

The present invention includes an automatic commodity or services billing and metering system that when installed does not damage any existing meters or gauges, will fit virtually all known meters and gauges, and has incorporated into the system programmable reading ability to allow reading and accumulation of data by unit, hourly, daily, weekly, monthly or any other form of counting required by the customer. The meters are read by various means, one method is by counting and or sensing radiation increases and decreases of radiation emitting from a meter hand or gauge passing a sensor to generate a count. The read data is then sent via the Internet through the telephone line, by satellite, or by cellular phone connection to an offsite central billing and payment processing center where the rate payer and the utility or customer will have various forms of programmable access to its consumption data.
