Abstract: The present invention provides a method, system and apparatus of interfacing a CardBay device (520) using existing Card and Socket Services (CSS) software (530). A CardBay controller (515) responds to card queries to indicate a pseudo card configuration which the CSS software (530) will recognize and support without the need for modification. The CardBay controller (515) further overrides the power control request generated in response to the pseudo card configuration information and signals a power control based on the voltage combination associated with the actual CardBay device (520). The controller also intercepts CIS read commands and responds with a CIS recognizable and specific to the inserted card. The controller (515) can further intercept legacy driver accesses and convert them into CardBay recognized accesses.

Abstract: Prior art attempts to reduce the power consumption demands of dual infrared transceiver laptop computer designs have.included enabling and disabling infrared ports at the user level. This solution requires the computer user to be involved in decision making with respect to infrared peripheral device discovery, and adds complexity to the overall infrared communications experience. Post connection dual IrDA port power management implements the infrared transceiver power down decision making in software, based upon activity inputs from the infrared link controller. Minor changes to the link controller at its device driver improve the user experience and the power consumption in dual IrDA port configurations.

Abstract: Bus repeaters offer electrical isolation by separating a single bus interface into one or more segments, and may provide cost advantages over bus bridges. There is a class of electrical equipment that can utilize the advantages offered by bus repeaters, and in addition to these advantages need to separate the bus segments by a distance greater than can be offered by the typical single chip repeater. What is disclosed here is a method for creating bus interface segments by use of a repeater that consists of two or more devices separated by a physical link.

Abstract: The disclosed invention utilizes a host controller's mechanism to start an isochronous transmit stream on a particular IEEE1394 bus cycle to calculate an offset value from the first time stamped packet that is transmitted in a CIP stream. Packet generating applications indicate the desired offset through the difference of programmed time to start transmitting and the value placed in the first time stamp field. This offset is then applied to the time stamps that are inserted in the remainder of the packets.
