摘要： The present invention provides a system, computer program product and a method for overlapping boundary data of an audio information track which includes ending data from a previous track and starting data from a succeeding track. By doing this, the ending data from a previous track and the beginning data from a succeeding track are available for the compression process. The compression program then manipulates the additional appended data in order to generate the compressed audio. Later, by severing the overlapping appended additional information before recombining the tracks, the resulting No-Pause CD audio stream is free from distortion and mismatch.

摘要： A system and method is provided for dequeuing connection requests in a data communications system comprising a calling subsystem and a called subsystem connected by a serial simplex switch. The connection requests are made by the calling subsystem to the called subsystem by sending a connect request message to the switch and queuing the connect request message in a buffer therein. The switch establishes a connection between the calling subsystem and the called subsystem by thereafter queuing the connect request message in a buffer in the called subsystem. Concurrently, the switch sends a connect request acknowledge message to the calling subsystem while the calling subsystem sends a connect request dequeue message to the switch. To prevent loss of synchronization between the calling subsystem and the switch, the connect request dequeue message received by the switch is interpreted as a disconnect request message and the connect request acknowledge message received by the calling subsystem is interpreted as a connect request dequeue acknowledge message. The connect request dequeue message and the disconnect request message are identically serially encoded, as are the connect request acknowledge message and the connect request dequeue acknowledge message, to enable such interpretation.

摘要翻译： 提供了一种系统和方法，用于在包括由串行单工交换机连接的调用子系统和被叫子系统的数据通信系统中出列连接请求。 通过向交换机发送连接请求消息并将连接请求消息排队在其中的缓冲器中，由呼叫子系统向被叫子系统进行连接请求。 交换机之后通过在被叫子系统的缓冲区中排队连接请求消息来建立呼叫子系统和被叫子系统之间的连接。 同时，交换机向呼叫子系统发送连接请求确认消息，而主叫子系统向交换机发送连接请求出队消息。 为了防止主叫子系统和交换机之间的同步丢失，交换机接收到的连接请求出队消息被解释为断开请求消息，由呼叫子系统接收到的连接请求确认消息被解释为连接请求出队确认消息。 连接请求出局消息和断开请求消息被同样地串行编码，连接请求确认消息和连接请求出队确认消息也是如此，以实现这种解释。

摘要： A sequencing scheme is provided for prioritizing bus operations occurring in simplex switches which interconnect subsystems in a data communications system, thereby yielding improved aggregate system data throughput. The sequencing scheme provides procedures which simultaneously accommodate (i) concurrently pending requests to a first control bus which processes only circuit switched operations and (ii) concurrently pending requests to a second control bus which processes only packet switched operations, in an order which optimizes link level control message throughput of the simplex switch. The control messages which are coordinated by the sequencing scheme include connect and disconnect requests, connect and disconnect request acknowledgments, and data acknowledgments. All connect request and disconnect requests are managed by a connection processing (CP) bus, which operates as a circuit switching bus, and all data acknowledgments and connect request acknowledgments from subsystems attached to a cascaded switch are made over an out-of-band (OB) bus, which operates as a packet switching bus. Because connect and disconnect operations over the CP bus can proceed independently of acknowledgment operations over the OB bus, the sequencing procedures for each of the control buses are permitted to operate independently and simultaneously.

摘要： A serial simplex switch design is provided which includes I/O ports each of which is configurable specifically for attachment to a data communications subsystem or, alternatively, for cascaded connection to a similarly configured I/O port on another switch. The switch provides a packet routing function including input and output buffers for each of its I/O ports wherein packets of control messages sent by one subsystem are temporarily stored prior to being delivered to the appropriate destination subsystem. When configured to be directly attached to a subsystem, the I/O ports separate control messages from incoming integrated data and control message strings. In a cascade configuration, however, a mechanism is provided wherein data and control messages are separated into two physical paths to eliminate the delays associated with integrated data and control message flow through the cascaded I/O port. Each I/O port is configurable to either of these methods of operation by means of programmable latches associated with the I/O port.

摘要： A cable for the transmission of audio frequency currents with reduced distortion has at least one pair of electrical conductors insulated from one another. A ferromagnetic foil is closely (less than one half millimeter) applied to the conductors. The ferromagnetic foil couples the equal and opposite external magnetic fields generated by the signal currents. This greatly reduces distortion due to the frequency-dependent magnetic effects on signal transmission.

摘要： A game programming system uses rewritable cartridges that are compatible with commercially available game systems to produce game cartridges at a point-of-sale location so that retailers only need to stock sufficient uniquely designed game blanks to meet consumer demand. A game programmer or programming device loads digital content from computer storage to a rewritable game cartridge incorporating reprogrammable flash memory. The system includes flash rewritable cartridge identification hardware that allows verification of the cartridge to identify it as proprietary to a particular manufacturer or authorized dealer. The system provides for game content to be erased from the cartridge and new game content to be programmed so that the cartridge can be reused time after time to house any number of programs. During a cartridge write operation, a game programmer interface accepts data stored in a personal computer (PC) and fills first in first out (FIFO) memory. A sequencer generates addresses, proper commands, control signals, and timing signals, and sends the game content from the FIFO memory to the game programmer which passes the information to the reprogrammable game cartridge. The sequencer enables the game programming system to write data to the reprogrammable game cartridge very rapidly. The game programmer provides an interface between the game program storage and reprogrammable game cartridge. The programmer may include multiple slots or sockets and accommodate cartridges from different manufacturers with different game formats.
