摘要:
The oxygen-selectivity of an atomic emission detection system is enhanced by introducing a carbon-containing, preferably non-oxygenated, gas as a portion of the reagent gas. In preferred embodiments, the reagent gas is nitrogen and/or hydrogen and up to about 50 volume percent of a C.sub.1 -C.sub.4 hydrocarbon gas.
摘要:
The radio frequency powered gas discharge tube of an atomic emission detector is cooled with a flow of liquid, and means are provided for grounding points in the flow that are on opposite sides of the radio frequency field so as to reduce the amount of radio frequency energy escaping from the discharge tube in the liquid.

A surgical device includes a first fastener having a planar profile, a second fastener having a concave surface, and a suture that can be manipulated to change a distance between the first and second fasteners. The second fastener has a curvature that substantially matches the curvature of a top surface of a clavicle bone in a direction perpendicular to a long axis of the clavicle bone. A method of treating an acromioclavicular joint injury includes forming axially aligned passages through a patient's clavicle and coracoid process, passing a fastener having a concave surface through the passages, positioning the concave surface of the fastener against a top surface of the patient's clavicle with a long axis of the fastener extending perpendicular to a long axis of the clavicle, positioning a fastener having a planar profile below the patient's coracoid process, and adjusting a suture that couples the fasteners.
摘要:
The present disclosure relates to a two-piece implant. The implant includes a first piece having at least two prongs and a protrusion located between the prongs and a second piece coupled to the first piece, wherein the second piece is configured to rotate relative to the first piece. A method of tissue repair is also disclosed.

摘要:
In hardware, performing computations on a stream typically requires handshaking signals to provide flow control. Many different handshaking protocols are available, and they are typically implemented in an ad hoc manner suited to the current design. An approach according to the invention uses a subset of the possible flow-control protocols in an effort to achieve a maximum amount of flexibility and reusability, while requiring only a moderate level of overhead when compared to manually-designed systems.

Data objects are organized into attributes and can be acted upon using predefined actions and associated types to greatly simplify user accessibility to such data objects through the limited user interface and bandwidth capabilities of a mobile device. Each data object is associated with a numerical identifier such that the user can easily identify a data object of interest using the limited data entry capabilities of the typical mobile device.
