A fibre channel storage area network (SAN) provides virtualized storage space for a number of servers to a number of virtual disks implemented on various virtual redundant array of inexpensive disks (RAID) devices striped across a plurality of physical disk drives. The SAN includes plural controllers and communication paths to allow for fail-safe and fail-over operation. The plural controllers can be loosely-coupled to provide n-way redundancy and have more than one independent channel for communicating with one another. In the event of a failure involving a controller or controller interface, the virtual disks that are accessed via the affected interfaces are re-mapped to another interface in order to continue to provide high data availability. In particular, a common memory storage device is connected to the back-ends of every controller to provide a storage area. In this manner, the common memory storage device can be accessed via operations similar to those a controller already uses to presently access the physical disks which are connected to the back-end of the controllers.

The present disclosure describes a device and methods for safely and accurately placing screws into bones with a powered driving device. By employing multiple layers of fail-safe features and image-guidance systems, the powered driving device provides safe, accurate, and efficient screw placement. That is, the powered driving device may continuously monitor a screw advancement and placement and may automatically shutdown when improper placement is detected. Monitoring placement may be conducted by a microcurrent-monitoring system, by an image-guidance system, or by any other appropriate sensory system. Additionally, upon detecting that screw insertion is complete, the powered driving device may be automatically shutdown. As screw placement is continuously simulated by image-guidance in real time, multiple redundant verification steps are eliminated, providing highly accurate screw placement while decreasing clinician error, device contamination, and surgical time, the decreased surgical time associated with decreased patient-recovery time and associated medical costs.

Secondary resonant pickup coils (102) used in loosely coupled inductive power transfer systems, with resonating capacitors (902) have high Q and could support large circulating currents which may destroy components. A current limit or "safety valve" uses an inductor designed to enter saturation at predetermined resonating currents somewhat above normal working levels. Saturation is immediate and passive. The constant-current characteristic of a loosely coupled, controlled pickup means that if the saturable section is shared by coupling flux and by leakage flux, then on saturation the current source is terminated in the saturated inductor, and little detuning from resonance occurs. Alternatively an external saturable inductor (1101, 1102) may be introduced within the resonant circuit (102 and 902), to detune the circuit away from the system frequency. Alternatively DC current may be passed through a winding to increase saturation of a saturable part of a core. As a result, a fail-safe pickup offering a voltage-limited constant-current output is provided.

The present invention contributes to advancements in the art of inventory management and distribution by providing a system and method for processing, distributing, and tracking reusable inventory items. Reusable articles, such as surgical garments and accessories, are adapted with radio frequency identification (“RFID”) tags having unique identification numbers. A “reader” is used to retrieve stored information from the tags without requiring direct contact or clear line-of-sight. The reusable articles are processed and distributed using an inventory management system wherein lifecycle data is obtained for each reusable article. The reusable articles are distributed to the end users from central processing facilities, used, returned, cleaned, inspected, folded, sterilized, and returned to inventory for re-distribution. Periodic quality control inspections are conducted in response to predetermined usage parameters. The use of RFID tags and a corresponding computer network allows for the acquisition of data corresponding to each reusable article within a distribution system having multiple remote distribution and processing facilities. The acquired data is transmitted to a central computer processing system via a secured wide area computer network for use and analysis. Data processing computer servers at each remote distribution and processing facility electronically linked to a central data processing server provide a fail-safe network for acquired data.

A fail-safe lug is carried by an engine frame member and receives a clevis carried by an engine mount member. The mount member includes side links that transmit transverse loads between the engines and the airframe and a thrust link that transmits axial, engine thrust loads between the engine and the airframe. A fail-safe pin is carried by the clevis and has an outer diameter that is smaller than an aperture in the lug and through which the pin passes, so that no loads are imposed on the fail-safe pin in normal operation. When one or more of the links are no longer capable of transmitting loads, the fail-safe arrangement becomes operative to accommodate the loads transmitted between the engine and the airframe.
