摘要:
A subscription television system and method in which billing information regarding programs actually viewed by a subscriber of the system is accumulated over non-dedicated telephone lines. A scrambled television program signal containing a block of television program material, a program identification code unique to the block of program material, and a program category code, is broadcast. The codes are preferably included in the vertical retrace interval of the video portion of the program signal and the transmitted program signal is selectively received at a subscriber station and selectively unscrambled to permit viewing of the block of program material being transmitted in response to subscriber action indicating acceptance for viewing of the block of program material. The received program category code is compared with a locally generated category code to determine whether the program is acceptable for viewing. The program identification code is detected and stored for subsequent transmission in response to the subscriber action indicating acceptance for viewing of the received block of program material.The program identification code stored at the subscriber station is selectively accessed from a remote location over telephone lines on other than a real time basis (e.g., a periodic basis) to thereby provide billing information at the remote location as to programs actually viewed by the subscriber. The subscriber can thus be billed monthly or on some desired periodic basis for programs actually viewed during the preceding period. The billing period can be varied from the remote location to provide a means to control the number of programs which a subscriber can receive.

摘要:
A telephone data accumulator system for accumulating data at a central station through connection of the central station to a remote subscriber's station, including a data accumulator, by way of nondedicated telephone lines. The remote terminal is selectively conditioned to generate dialing signals and to thereby provide selective connection of the accumulator to the telephone lines from the remote subscriber station. A preconditioning circuit such as timing means or a broadcast signal decoder at the subscriber's station conditions the remote terminal and provides a short time window during a time of the day when the telephone there is not likely to be used for normal telephone calls, and the call is made to the central station during the time window to cause connection of the data accumulator to the telephone lines. The data in the data accumulator is thereafter transferred from the remote station to the central station over the telephone lines.
摘要:
A subscription television system and method in which billing information regarding programs actually viewed by a subscriber of the system is accumulated over non-dedicated telephone lines. A scrambled television program signal containing a block of television program material and a program identification code unique to the block of program material is transmitted at a predetermined carrier frequency. The codes are preferably included in the vertical retrace interval of the video portion of the program signal and the transmitted program signal is selectively received at a subscriber station and selectively unscrambled to permit viewing of the block of program material being transmitted in response to subscriber action indicating acceptance for viewing of the block of program material. The program identification code in the program signal received at the subscriber station is detected and stored for subsequent transmission as an electrical signal in response to the subscriber action indicating acceptance for viewing of the block of program material.The program identification code stored at the subscriber station is selectively accessed from a remote location over telephone lines on other than a real time basis (e.g., a periodic basis) to thereby provide billing information at the remote location as to programs actually viewed by the subscriber. The subscriber can thus be billed monthly or on some desired periodic basis for programs actually viewed during the preceding period.
摘要:
A system wherein a telephone calling signal from a central station initiates the connection of a remote terminal, including a data accumulator, at a subscriber's station to a nondedicated telephone line for reading by a billing processor computer at the central station. In one embodiment, sequential ringing signals having a different time spacing than the signals from a normal telephone call may, through operation of a ring muting circuit at the subscriber's station, condition the remote terminal to intercept the ringing signals and to provide selective connection of the accumulator to the line without disturbing the subscriber or disrupting normal telephone operation. Alternatively, timing means may be operated at the subscriber's station to condition the remote terminal and provide a short time window during a time of the day when the telephone there is not likely to be used for normal telephone calls so that a call made from the central station during the time window will cause connection of the data accumulator. In both embodiments conditioning and connection of the subscriber terminal are accomplished without actuating the subscriber ringer.
摘要:
A method and a system for secure transmission and reception of a video signal wherein parts of the video signal arranged in a first predetermined sequence are delayed in relation to each other to form an encoded video signal having its parts rearranged in sequence relative to their positions in the first predetermined sequence. Rearrangement of the video signal parts is accomplished by storing successive parts of the video signal and retrieving the stored parts so that the transmitted video signal has in parts arranged in a sequence other than their normal sequence. A decoder at a remote location is provided for receiving and restoring the transmitted sequence of video signal parts to its original sequence. In a television scrambling system, the parts of the video signal are fields, lines or segments of lines and, rearrangement of the sequence of video signal parts is accomplished on a line segment, line or field basis. Codes may be transmitted to the remote location with the video signal or otherwise to indicate the manner in which the parts of the video signal have been rearranged.

A virtual shuffleboard table gaming apparatus including a housing having a playing field, a game acquisition circuit, and a display. As a puck is propelled towards a puck return at the distal end of the playing field, the puck temporarily obstructs at least two beams from transmitters. Sensors that receive the transmitted beams provide information to the game acquisition circuit indicative of the time when the beams were blocked and unblocked. The duration of time the beams are block are used by a game controller to calculate the angle of travel, location, and velocity of the puck. This information is then used by the game controller to determine the travel path and resting place of a virtual puck on a virtual playing field, as well as determine whether the virtual puck rests in a scoring zone and maintain a game score.

A MEMS microphone has a backplate and a movable diaphragm that together form a variable capacitance. The backplate has a backplate surface and, in a corresponding manner, the diaphragm has a diaphragm surface that faces the backplate surface. At least one of the backplate surface and the diaphragm surface has at least a portion with a Hurst exponent that is less than or equal to about 0.5.

A lubricant additive gel formed by the gellation of two or more lubricant additives for the slow release of the additive components into a fluid. The lubricant additive gel slowly releases into its component lubricant additives when contacted with the fluid such as an oil thereby serving as a lubricant fluid such as an oil thereby.
