Abstract: A method and a system are used to manage fonts in print jobs with more than one context where at least some of the contexts include text strings. Print jobs may be divided into portions, called contexts, so that they are easier for a print manager to manage. These larger contexts are called graphic sets. Each of these graphic sets is sent to the printer driver consecutively. Each text string has a font associated with it. The font data for each text string is read from the operating system and cached into memory at the time each string is received by the printer driver. After all individual text strings elements of a given graphic set have been received by the printer driver, the context is stored and the cached fonts are stored with the context. After all of the contexts of the print job have been received by the printer and stored, each context is restored and rendered. The graphics sets may be restored in any order. The fonts stored with a context are also restored when the context is restored.

Abstract translation: 一种方法和系统用于管理具有多个上下文的打印作业中的字体，其中至少一些上下文包括文本字符串。 打印作业可以分为部分，称为上下文，以便打印管理员更容易管理。 这些较大的上下文称为图形集。 这些图形中的每一个都连续发送到打印机驱动程序。 每个文本字符串都有一个与之相关联的字体。 每个文本字符串的字体数据从操作系统读取，并在打印机驱动程序接收到每个字符串时缓存到存储器中。 在打印机驱动程序接收到给定图形集合的所有单独文本字符串元素之后，上下文将被存储，缓存的字体与上下文一起存储。 在打印机接收到打印作业的所有上下文并存储之后，将恢复和呈现每个上下文。 图形集可以以任何顺序恢复。 当上下文恢复时，还会恢复存储有上下文的字体。

Abstract: A tape drive method and apparatus is disclosed wherein payload data is sent from a host computer device to a tape drive data storage device in data block sizes which are specified by the host computer, for example in the case of a tape drive presenting a CD-ROM image, in 2 kbyte blocks, whereas the tape drive writes to tape media in an optimal block size required to keep the tape media streaming across the tape heads, for example 8 kbyte blocks. Conversion between block size is achieved by buffering incoming payload data in a buffer, and by reading or writing to the tape media in the optimum block size.

Abstract: A document transfer system enabling a consumer to obtain a document from an owner upon payment uses a cryptographic protocol involving the consumer, the owner, a document source, such as a printer, and a mediator, the protocol comprising the following steps: (a) the consumer requests a document; (b) the owner provides the source with first and third portions of the key and provides the mediator with a fourth portion of the key, which can combine with said first portion to generate the complete key; (c) the consumer provides the owner with the payment; and (d) the owner provides the source with a second portion of the key, which can combine with said first portion to generate the complete key. A printer 1 for use in the above system comprises a document memory 2 for storing a received encrypted document, a key memory 3 for storing a first cryptographic key portion, a processor 4 for receiving a second cryptographic key portion and combining it with the first key portion to form a complete cryptographic key which is supplied to a decrypting module 5. The encrypted document is supplied to the decrypting module 5 whereupon the document is decrypted and supplied to the consumer.

Abstract: The invention relates to power regulation of integrated circuits such as microprocessors. It suggests measuring instantaneous power consumption inside of the integrated circuit (13), by sensing state changes of the transistors of the units (14, 16, 18 20, 22) of the circuit. Based on the sensed power consumption, an instantaneous power consumption for the whole circuit may be computed and transmitted to a voltage regulator (27). The voltage regulator changes the voltage according to the computed power consumption; the regulator may thus precompensate power surges, and limit voltage transients.

Abstract: In a wireless network containing battery powered stations, one station is designated as a control point (CP). Each of the remaining stations has two operating modes: an active mode in which it receives and transmits messages, and an inactive or sleep mode which incurs reduced power consumption. The Control Point periodically transmits a beacon signal, and each station switches to its active mode to receive at least some of these beacon signals. A beacon signal may indicate that data is available for transmission to a particular station (from another station), in which case that particular station then broadcasts a message to indicate that it is awake and can receive messages. A beacon signal also indicates whether a broadcast period is in progress, and time to elapse until a next possible broadcast period will commence; if the Control Point has previously received and stored any broadcast messages it will re-broadcast them during the next following broadcast period and the remaining stations will react by remaining in active mode for the duration of that period.
