Abstract: A field transducer (30) for determining position or orientation in a medical instrument locating system is placed at an arbitrary position or orientation with respect to a feature (62) of the instrument (46). The transducer (30) may be attached at an arbitrary location on the instrument (46), or the instrument (400, 404) may be bent as desired by the user. A transform relating position or orientation of a feature of the instrument to position or orientation of the transducer is obtained in a calibration cycle. A field transducer may be part of a disposable unit which is irrevocably altered when used with an instrument, so that the unit cannot be reused.

Abstract: An optical switch device for switching test signals to the terminated ends of a predetermined number of optical fibers in an optical fiber cable. The optical switch device contains a first optical port for receiving the test signals. A plurality of optical second ports are provided, wherein the number of second optical ports is less than the number of optical fibers in the cable to be tested. The optical connector ports are connected to the terminated ends of optical fibers in the optical cable by a plurality of detachable adapters. Each of the adapters has a base connector that selectively engages one of the second optical ports on the optical switch device. A plurality of optical leads extends from the base connector of the adaptor. The optical leads terminate with a plurality of plugs that are adapted to selectively engage some of the terminated ends of the optical fibers in the optical cable. The plugs at one end of the adapters are first connected to the optical fibers in the optical cable. The base connectors coupled to the plugs are fewer in number than optical fibers by a ratio of at least 1:2. The base connectors are then connected to the optical switch, thereby allowing for a connection operation that is more time efficient and space efficient than was previously available.

Abstract: In the prior art, the weighted fair queuing scheduling process has emerged for transmitting data packages. This process exclusively establishes a lower limit of the data package transmission rate. In order to also achieve an upper transmission rate limit, the disclosed process provides for another scheduling process to be carried out before the other process. The disclosed process runs in a first scheduler which is provided only once, whereas the process which establishes the lower transmission rate limit runs in a scheduler connected downstream of the first scheduler and if required several times.

Abstract: A casing accommodating therein a pair of balance shafts below the cylinder block comprises an upper casing and a lower casing that can vertically be split, and an oil pump body is molded integrally with one of the upper and lower casings. In addition, one end of each of the two casings is inserted into the oil pump body for support therein, and the two balance shafts are each supported on a bearing provided between the two casings in such a manner as to be split into two halves at an intermediate portion or the other end thereof . With this construction, the oil pump body can be molded together with the casing, thereby making it possible to reduce the number of components used and man hours for assembling. In addition, since the bearings can be split into two halves, when compared with other portions of the balance shafts, the journal portion can be thinned, thereby making it possible not only to reduce the sliding friction but also to make the casing smaller in size and lighter in weight.      More over, the degree of freedom of designing balance shafts can also be improved. With the balance shaft supporting structure for an engine the durability of a balancer, as well as the degree of freedom of designing the same are improvided without making the engine larger in size and increasing the number of components used.

Granted: 2006-12-12
Abstract: An emergency extrication collar comprising a flexible band for encircling the wearer's neck, and a chin support member which may be readily adjusted in elevation with respect to the band so as to permit adjustment to fit patients having varying neck sizes. The chin support member is connected to the band by means of a post which is slidably connected to a vertical strap on the band, and such that the elevation of the chin support member above the post, and thus the neck size of the collar, may be adjusted by simply sliding the post and chin support upwardly to any selected size between the size extremes. A  pawl and ratchet interconnection between the post and strap precludes movement in the opposite direction. The collar is secured in its adjusted size by means of a locking arm which is pivotally mounted on the post, and movement of the locking arm to its release position also releases the pawl and ratchet interconnection.

Title: Swivel torque tube arrangement
Inventor: TURNER MALCOLM E
IPC: B63B21/50
Filed: 1999-06-16
Granted: 2004-08-17
Abstract: An improved product transfer system is disclosed for a turret moored FPSO (10). A swivel stack torque tube (105) is provided such that the swivel stack (100) can be recessed below the manifold decks (103), but still allow swivel torque reactions to be transferred to the ship structure. Recessing of the swivel stack downwardly with respect to the manifold decks reduces the height of the access structure and locates the swivel stack center of gravity closer to the center of gravity of the vessel.      This arrangement results in reduced loads to the turret structure (20) which supports the swivel stack and reduced height and size of the access structure for the swivel stack.
