A set of badges is distributed at a party to help attending party-goers "break the ice" with members of the opposite sex. Each girl at the party is given a badge of one type, and each boy is given a badge of another type. Each badge has a light that can blink, but it is normally off. Each badge transmits a contact signal that is picked up by any opposite-type badge that is in proximity with it. If the two badges blink, indicating a match, the facing boy and girl must start talking to each other. Either both badges will blink or neither will, but whether or not they blink is based on chance. Each party-goer is given a hidden remote control which, when turned on, increases the probability of the lights blinking. Provision is also made for an exchange of personal information via the badges when a match is made.

There is disclosed a multi-layer tape system, of the type disclosed is Castelluzzo application Ser. No. 930,700, U.S. Pat. No. 4,182,789, for applying register marks or other symbols to aligned art-work sheets used in the graphic arts field. In a two-layer system, each of two superimposed tapes has aligned markings thereon. A weak adhesive secures the two tapes together, and the two outer surfaces are coated with a strong adhesive. In a four-layer system, a separator is disposed between a pair of two-layer systems; the separator has holes therein so that the two tape systems can adhere to each other and remain in alignment, contact being made in the regions of the holes. The relative adhesive strengths maintain the system integrity prior to use while also permitting tape sparation during use. Instead of using clear tapes and printed markings as in the Castelluzzo system, opaque or colored tapes with punched markings are employed. This greatly simplifies manufacture because there is no need to align pre-marked tapes during the lamination step; the registration markings are punched after lamination. Color contrast is achieved by use of the opaque or colored tapes.

An access control system for litigation document production. Documents are produced as stored images on an optical disk. Documents which are to be redacted or maintained confidential are stored in encrypted form. As the litigation progresses, access by the opposing counsel/party to additional documents can be effected by distributing appropriate decryption keys.

A compressed digital multi-channel video communications system having at least one auxiliary channel. The other channels are assigned to respective program sources. These channels are prioritized. The auxiliary channel works with the assigned channel which has the highest priority and which also requires additional bit capacity; the two channels carry bit streams whose combined rate exceeds the highest bit rate that can be carried by a regularly assigned channel. As the needs of the assigned channels continuously change, the auxiliary channel works with different channels.

An exercise system and method for insuring that a user exercises at a level at or above a preset level. The user exercises in front of TV. Noise is mixed with the TV signal if the exercise level drops below the preset level. The result is instantaneous biofeedback and maintenance of the desired exercise level.

A cartridge-controlled system whose use is limited to authorized cartridges. Blocks of instructions of a program designed to run on the machine are encrypted by the machine manufacturer using the private key of a public-key cryptosystem pair. The machine, during an initialization step following the insertion of a new cartridge, decrypts information strings stored in the cartridge through use of the associated public key, and stores the resulting decrypted instructions in random access memory. The machine microprocessor then accesses the instructions in the random access memory. Although the public key may be widely known, as long as the private key is kept secret, there is no way for an unauthorized software/cartridge supplier to encrypt a program such that following decryption in the machine there will result an intelligible sequence of instructions.

There is disclosed a board game. The board itself has three tracks with a plurality of interconnecting segments therebetween. A group of switches is provided, each adapted to be placed on the board in the region of one of the interconnecting segments. The switches serve to define an operative path from a start point to a finish point which includes selected segments of the tracks. Each player has a set of value pieces and the players take turns and alternately place their value pieces on random ones of a set of identifiable positions on the tracks. Thereafter, the players take turns and alternately place the switches on the board on a random basis until a complete operative path is defined. A marble is then rolled down the path to expose the values of the player pieces which it passes, and the players add up their respective scores.
摘要:
A board game in which two players have facing sets of numbered pieces, each piece of each player being capable of capturing a predetermined number of the other player's pieces in accordance with their numerical values. Each turn consists of a player capturing those pieces which he can, removing the captured and capturing pieces from play, and then making a "move." A move involves a player re-positioning one of his pieces which remain in play in his line of pieces. The type of move taken by a player is determined by the roll of a die.

There is disclosed a two-way cable system in which the deliberate introduction of continuous upstream message interference at any subscriber terminal does not destroy the efficacy of the system. Each subscriber terminal is coupled through an interface unit to the cable, and the interface unit permits upstream transmission of a message from the respective terminal only following recognition by the interface unit of the downstream transmission of the address of the respective terminal. Because the interface units are located off the premises of the subscribers, a deliberately introduced interference signal on a subscriber line cannot reach the cable except during the respective time slot of the subscriber.
