A medical assembly includes a cannula and a scaling cap releasably coupled to the cannula. The cap includes a body and a sealing member integrally molded with the body to form a fluid-tight seal between the cap and cannula. The cap includes a member defining an opening for passage of a medical instrument therethrough in a fluid-tight manner. The member includes a first portion surrounding the opening and being thickened to limit tearing of the first portion, and a second portion surrounding the first portion being tapered down in thickness toward the first portion to increase flexibility of the member. The assembly includes a shaft receivable in a lumen defined by an inner surface of the cannula. The shaft includes a protrusion and the inner surface further defines a protrusion receiving formation.

Methods and systems for sculpting synthesized speech using a graphic user interface are disclosed. An operator enters a stream of text that is used to produce a stream of target phonetic-units. The stream of target phonetic-units is then submitted to a unit-selection process to produce a stream of selected phonetic-units, each selected phonetic-unit derived from a database of sample phonetic-units. After the stream of sample phonetic-units is selected, an operator can remove various selected phonetic-units from the stream of selected phonetic-units, prune the sample phonetic-database and edit various cost functions using the graphic user interface. The edited speech information can then be submitted to the unit-selection process to produce a second stream of selected phonetic-units.

The present invention relates to a drill guide for use in drilling an acetabular tunnel. The drill guide comprises a cannulated shaft having a handle towards a proximal end, and an offset arm towards a distal end. The arm is flexible or pivotable and has a distal tip for engaging the articular surface of the acetabulum, and is offset from a projected path of the shaft cannulation.

Disclosed are methods and apparatus for accessing data from electronic documents stored as print streams are disclosed. In one embodiment, an electronic document conforming to one of a plurality of print formats is obtained. The electronic document is parsed according to the one of the plurality of print formats to generate an intermediate data structure conforming to an intermediate format such that the electronic document is converted to the intermediate format, wherein the intermediate format is different from the plurality of print formats. One or more rules are applied to obtain data for a plurality of regions of the electronic document from the intermediate data structure. The data for the plurality of regions of the electronic document that has been obtained from the intermediate data structure is stored or provided, thereby enabling a report to be generated using at least a portion of the data for the plurality of regions that has been stored or provided.

A method and apparatus suitable for controlling the power of a channel in an optical network are described. A control system for a variable optical attenuator includes a processing element arranged to: (a) receive a signal indicative of the radiation power of an optical signal output from a variable optical attenuator; (b) determine an error signal in dependence upon the received signal and a predetermined target radiation power level; (c) determine a control signal for controlling the attenuation of the variable optical attenuator in dependence upon the error signal and a gain factor; and (d) repeat the operations of (a) to (c). The control system is arranged to utilize a first value of the gain factor during a first time period and a second, lower value of the gain factor during a second time period. Such a control system can be used to control the introduction of a channel in a node of an automatically switched optical network.

A hip distractor includes a pair of distractor members and a support configured to be fastened to a surgical table. The support includes at least two mounts for coupling to a pair of joints that couple the distractor members to the support. Another hip distractor includes a pair of distractor assemblies that are configured to apply a distraction load to a patient. Each of the assemblies includes a joint for coupling the corresponding assembly to a surgical table. The joint permits vertical and horizontal angular adjustment of the corresponding assembly. A method of distracting a hip includes coupling a patient's legs to a pair of distractor assemblies and simultaneously adjusting a vertical angle and a horizontal angle of at least one of the distractor assemblies.
