摘要： An I/O processor for controlling data transfer between a local bus and an I/O bus. An Execution Unit, an I/O bus sequencer, and a local bus sequencer are connected to a register file. The register file is uniformly addressed and each of the Execution Unit, the local bus sequencer, and the I/O bus sequencer have read/write access to the register file. The register file is comprised of a plurality of register sets. The Execution Unit includes a programmed processor which is programmed to allocate the register sets among tasks running on the processor by passing register-set descriptors between the tasks in the form of messages. The local bus sequencer includes a packet-oriented multiprocessor bus, there being a variable number of bytes in each of the packets. The I/O sequencer includes logic for multibyte sequencing of data at a bus-dependent data rate between the I/O bus and the register file. Each of the tasks includes a task frame, each task frame including register-set pointers. The register-set pointers map between logical addresses used in the instructions of the tasks used to access the pointers and physical register-set addresses used to access the register. Programmed logic in each of the Execution Unit, the local bus sequencer, and the I/O bus sequencer dynamically allocate the register sets to the sending and destination tasks.

摘要： An apparatus and system are disclosed to extract breathable air from snow via a protective helmet. The apparatus includes a protective structure, at least one air intake cavity, and a mouthpiece. The protective structure defines an inner cavity and an outer surface. A portion of a user's head may be placed within the inner cavity. The air intake cavity or cavities are disposed on the outer surface of the protective structure. The mouthpiece is in fluid communication with the air intake cavity or cavities. Additionally, the mouthpiece is configured to allow a user to draw intake air from ambient snow through the one or more intake cavities and to the user's mouth upon inhalation. Advantageously, the apparatus and system provide a reliable mechanism for drawing air from ambient snow when a user, especially the user's face or head, is at least partially buried in the snow.

摘要： An apparatus and system are disclosed to extract breathable air from snow via an air extraction backpack. The apparatus includes an air-permeable extraction assembly that is attached to a backpack. The air-permeable extraction assembly has an air intake cavity. An air-permeable membrane covers the air intake cavity. A mouthpiece is in fluid communication with the air intake cavity. The mouthpiece draws intake air through the air intake cavity upon inhalation by a user. A transfer guide passes intake air from the air-permeable extraction assembly to the mouthpiece upon inhalation by the user.
