Abstract: A video game cartridge that can be plugged into a video game machine to enable a user to request and play a video game for a predetermined number of video frames. The cartridge has a receiver for receiving the video game program and the predetermined frame count in response to a request from the user. The program and frame count is then stored in a memory of the cartridge. Finally, the cartridge has a counter which changes its value when the user is actively playing the video game program. The counter ceases to change its value when the user is not playing the video game program. When the counter reaches a predetermined limit, the user is no longer authorized to play the video game program.

Abstract: In a method for switching voice and data over a multistage interconnection network (MIN) (10), a plurality of bits are stored in respective storage locations (2-1, 2-2, ... 2-512) of the switching elements (5) of the MIN. Each storage location of a switching element represents a particular time slot in a frame or a sequence of frames. Bits (27, 26) stored in each location represent specific conditions of the inputs and outputs of the switching elements and also indicate which inputs of the switching elements will be connected to which outputs of the switching elements. This storage of control information in the switching elements allows the switching network to rapidly and simultaneously change connections through the switching elements of the network.

Abstract: DISTRIBUTED VOICE-DATA SWITCHING ON MULTI-STAGE INTERCONNECTION NETWORKS A method of switching synchronous and asynchronous data packets through a multi-stage interconnection network (MIN), so as to insure that packets with the highest assignable priority level will never be blocked at any stage of the network. More specifically, this invention relates to a method of switching voice and data packets over the MIN wherein each of the address bits in each packet determine the connection to be established at each particular stage in the network and wherein each packet has therein a priority level. In each time slot of a frame, the priority level of the packets stored in a particular originating adapter are compared and the packet with the highest priority level in each adapter is forwarded through the MIN and routed through the MIN as described above. Also, at each subswitch at each stage of the MIN, if two or more packets request the same subswitch output, only the packet with the higher priority is forwarded to the subswitch output. A packet will be assigned the highest priority only if a corresponding packet for a given circuit connection with second highest priority level was successfully transmitted through the MIN.
