Abstract: In a portable FireWire compatible device, a direct memory access (DMA) bus switch coupled by way of a DMA bus to a central processing unit (CPU), a local hard drive (HDD), and a FireWire port, provides a direct connection between the FireWire port and the HDD bypassing a main bus and the CPU when a data transfer request is received and processed by the CPU. Otherwise, until the data transfer request is received and processed, the CPU is directly connected to the HDD. In this way, a high speed data transfer between the FireWire port and the HDD is provided only when an appropriate data transfer request is received and processed.

Abstract: High-speed data streams are exchanged between two digital computing devices one or both of which lacks DMA. Data transfers are performed by the devices using High-Level Datalink Control (HDLC) frames. An initiating device indicates that it wishes to exchange data with the other device by sending an HDLC frame with data stream indentification and other information. The initial HDLC frame is sufficiently short that at least an essential portion of the frame can be stored in a receive buffer of the interface circuitry. Although the receiving device may not receive the entire HDLC frame correctly because of the possibility of an overrun condition, enough information is preserved in the interface circuitry to complete the transaction. The responding device then proceeds to read or write data at high speed using a series of exchanges with the initiating device.

Abstract translation: 在两个数字计算设备之间交换高速数据流，其中一个或两个缺少DMA。 数据传输由使用高级数据链路控制（HDLC）帧的设备执行。 启动设备指示希望通过发送具有数据流标识和其他信息的HDLC帧来与其他设备交换数据。 初始HDLC帧足够短，使得帧的至少一个基本部分可以存储在接口电路的接收缓冲器中。 虽然接收设备由于可能出现溢出状况而不能正确地接收整个HDLC帧，但在接口电路中保留足够的信息来完成交易。 响应装置然后使用与发起装置的一系列交换来高速读取或写入数据。

Abstract: Copy protection techniques that utilize a watermark and a permission key are disclosed. The copy protection techniques can provide single-copy copy protection in addition to different levels of copy protection. The permission key and the watermark can also permit the invention to yield variable levels of copy protection. In one embodiment, content including a watermark is transmitted to a recipient. The recipient is allowed to read the content but not record the content unless the recipient possesses a permission key.

Abstract: Improved approaches for users of computing devices to interact with graphical user interfaces are described. According to one aspect, a rotational user action supplied by a user at a user input device is transformed into linear action with respect to a graphical user interface. According to another aspect, a portion of an extended list of items is displayed by a graphical user interface and, through rotational user actions at a user input device, the portion of the list being displayed can be varied with welcomed ease of use. Although the type of computing device can vary, the improved approaches are particularly well-suited for use with a portable media player.

Abstract: In a first embodiment, multi-speed concatenated packet strings are transmitted by a first node on a serial bus. To accommodate multi-speed packets, a speed signal is transmitted immediately prior to the packet. In a second embodiment, ACK-concatenation is used to allow a node to transmit a data packet immediately after transmitting an acknowledge signal on the bus. The data packet need not be related to the ACK packet. In a third embodiment, a node which receives a first data packet followed by a data end signal on a child port, concatenates a second data packet onto the first data packet during retransmission. The second data packet is also transmitted down the bus in the direction of the node which originally transmitted the first data packet.

Abstract: The present invention dynamically brokers object messages between object models. An mediating component provides a bridge between object models such that messages can be transmitted in either direction between object models. The mediating component can be resident on a client machine, a server machine, or both. The mediating component can be used as a bridge between two instances of the same object model running on different machines. Thus, network communication is made possible for objects of an object model that otherwise lacks a networking capability. The mediating component maps a client object to a server object through proxy objects and stub objects. The proxy object always responds affirmatively when queried by a client object whether a server object can execute a particular method. A client object's message is forwarded to a server object. The mediating component performs any necessary translation of arguments or format of the message. In addition, the mediating component translates a server object's response.

The computing device includes a shock mount assembly that is configured to provide impact absorption to sensitive components such as a display and an optical disk drive. The computing device also includes an enclosureless optical disk drive that is housed by an enclosure and other structures of the computing device.

Abstract: An improved hinge mechanism for use with a portable computing device is disclosed. The present invention relates to a hinge mechanism that is suitable for use in a portable computing device. According to one aspect of the present invention, a hinge mechanism that is used with a door in a portable computing device includes a spring coil, a stopper, and a pivot arm. The spring coil has a compressive state, e.g., the spring coil may be compressed or decompressed. The pivot arm is coupled to the stopper, and includes a first section as well as a second section. The first section is arranged to be positioned substantially within the spring coil, and the second section is arranged to be coupled to the door. Translational motion of the pivot arm causes the stopper to cause the compressive state of the spring coil to change. In one embodiment, the translational motion of the pivot arm causes the stopper to cause the spring coil to compress.
