Abstract: A method for obtaining solid-state metal borohydrides without toxic precursors and expensive solvents includes dry mixing of metal hydrides and metal polyhydro-closo-borate starting materials. High pressure and heating is also used in the method. These materials can be used for hydrogen storage, general reducing agents, organic synthesis, wastewater treatment, and paper pulp bleaching.

Abstract: A communication system has multiple communication buses and multiple bus controller cards each supplying at least two independent channels of communication between one or more hosts and the communication buses. One of the controller cards is designated as a primary controller card for managing the communication buses and resetting the communication buses such that if a controller card is inserted to or removed from the system then the buses are reset.

Abstract: A communication system with a plurality of interface slots includes control logic for determining and designating the status of one or more controller cards inserted in one of the slots such that: a controller card is designated as the primary card if it is inserted in an interface slot while the other slots are empty; a controller card in an interface slot with primary status retains its primary status while other controller cards are added or removed from the system; a controller card in an interface slot with a non-primary status assumes primary status if the controller card with non-primary status is plugged in a slot that after a power interruption is designated as the slot to assume primary status, or the controller card with primary status is removed from the system.

Abstract: A device includes a first SCSI bus, a second SCSI bus, a first bus controller slot, a second bus controller slot and a bus controller in one of the first bus controller slot and the second bus controller slot. The bus controller includes reset circuitry for generating a SCSI bus reset signal. The SCSI bus reset signal being used to reset the first SCSI bus when the bus controller is in the first bus controller slot and the first SCSI bus is isolated from the second SCSI bus. The SCSI bus reset signal being used to reset the second SCSI bus when the bus controller is in the second bus controller slot and the first SCSI bus is isolated from the second SCSI bus. The SCSI bus reset signal is to reset both the first SCSI bus and the second SCSI bus when the first SCSI bus and the second SCSI bus are bridged and one of the following conditions is met: the bus controller is in the first bus controller slot, or the bus controller is in the second bus controller slot and the first bus controller slot is empty.

Abstract: Method and system for enhancing the reliability of an available storage subsystem. Data storage units are equipped with a number of I/O controller-card adaptors that mate with complementary adaptors affixed to a number of redundant I/O controller cards. The data storage devices plug directly into I/O controller cards and receive all data, control signals, and power equally from the I/O controller cards, eliminating the need for a midplane circuit card.

Abstract: A method and system for facilitating reliable and fault-tolerant operation of a multi-peripheral-device enclosure for use in high-availability computer systems by redundant interconnection of redundant processors within the multi-peripheral-device enclosure. The redundant interconnection removes a potential single point of failure, and allows the redundant processors to share in control of other components within the multi-peripheral-device enclosure. The multi-peripheral-device enclosure can recover from failure of all but one of the redundant processors, as well as failure in all but one of the redundant busses used to interconnect the two processors.
