A method of reading configuration ROM in a serial bus device reads only portions of the ROM that are organized in a directory structure. Typically, the configuration ROM follows the IEEE 1212 and/or 1394 standards and uses an IEEE 1394 bus. Based on the information read from the configuration ROM, a connecting computer can determine the appropriate device driver to use for communications with the device.

After a reset on a bus, the topologies of nodes on the bus before and after the reset are accessed to identify nodes that are new to the bus. A host identifies itself in both the new topology data and the old topology data. Referring to the connectedness between ports of a node and other ports in the new topology, similarly connected nodes in the old topology are identified as matching. Identifying data present in the old data can be assigned to the corresponding node in the new data. Any nodes in the new tree lacking a matching node will require requests over the bus to obtain its identification data.

A method for linking work requests in a work queue with entries on a queue of completed requests. For each work queue, a tracking list is created. Each tracking list is linked to one queue of completed requests. When a work request is added to a given work queue, an entry is added to the associated tracking list. The entry in the tracking list contains all of the information needed to uniquely associate a completion queue entry to the work request that caused the completion queue entry. When a completion queue entry is retrieved from the completion queue, the tracking list for the work queue is searched for an entry corresponding to the completion queue entry. The work request that caused the completion queue entry is then identified from the information in the tracking list entry.

A swim fin is herein presented. The swim fin can include a frame and one or more louvered blades coupled to the frame. The swim fin can additionally or alternatively include a proximal mount coupled to a proximal portion of the frame and configured to attach to the leg of a swimmer, and a distal mount coupled to a distal portion of the frame and configured to attach to the leg, foot, or the ankle of a swimmer.

This present disclosure may relate to a pillow configured to receive a person in a face down position, the pillow including a receiving portion and one or more pathways. The receiving portion and pathways may be configured to deliver air to a user and to receive exhaled air from a user. The pillow may also include a chamber which may connect the receiving portion and pathways and one or more valves which may facilitate air exchange between the chamber and the pathways.
摘要:
A system for permitting remote user access to regions of memory that have been exported for remote direct memory access purposes. The system supports dynamically changing access privileges to remote users without requiring intervention from an operating system. The system may include a memory region table and a memory window table for supporting address translations. Entries in the memory window table may include a region remote access key and a window remote access key. The memory region table may include fields for a physical address, an access value, a protection domain value, and a length of memory region.

A process for preparing ring-halogenated .alpha.-methylstyrenes from the corresponding .alpha.-halocumenes is disclosed. The dehydrohalogenation is accomplished using only water and optionally an organic solvent. The process eliminates the need for added base and a phase-transfer catalyst.

An underwater breathing device, such as a snorkel, may include an exhalation valve. The exhalation valve is configured to produce positive end-expiratory pressure in the airway of a user of the underwater breathing device. The exhalation valve includes a plate defining an exhalation port and at least one chamber port, an exhalation conduit connected to the exhalation port, and a flexible membrane that is sealable against a surface of the plate. A lower portion of the exhalation conduit is divided by a septum which divides the exhalation conduit and the exhalation port into a first exhalation port connected to a first exhalation conduit and a second exhalation port connected to a second exhalation conduit. The flexible membrane is sized and positioned to be capable of sealing the first exhalation port and the second exhalation port.

Swim fins that attach to the legs of a swimmer to aid movement through the water. In one example embodiment, a swim fin includes an upper support frame, a lower support frame, a lower blade attached to the lower support frame, and at least one hinge assembly connecting the upper support frame to the lower support frame. The upper support is configured to be generally positioned along and attached to the front of a swimmer's lower leg between the swimmer's knee and ankle The lower support frame is configured to extend, in a swimming position, from a position proximate the swimmer's ankle to a position beyond the end of the swimmer's foot. The at least one hinge assembly allows the lower support frame to be rotated upward from the swimming position to a walking position. The walking position enables the swimmer to walk barefoot on a surface without the lower support frame nor the lower blade substantially contacting the surface.

A food flagging device has a flag stem, a time identification means, a magnet support platform, and a magnetic means. The time identification means is either attached to, or is contained within, the flag stem. The magnet support platform is either attached to, or is contiguous with, the flag stem. The magnetic means is attached to the magnet support platform and has a magnetic field that is sufficiently strong to hold the food flagging device to a stainless steel surface. The food flagging device is heat-resistant and is capable of being sanitized.
