Abstract: A method for estimating recall in database workflows involves assigning unique keys to documents in a database, generating a random permutation of the database, accessing coding decisions for documents, determining the longest prefix of the permutation with corresponding coding decisions, calculating the number of relevant documents, applying a confidence sequence generating algorithm to the prefix to establish a confidence interval on the relevant documents, and computing a confidence interval estimate on recall for the database. This method provides a systematic approach to assess recall in database workflows, enabling accurate evaluation of the retrieval performance of relevant documents within the database.

Abstract: A method of joining and sealing a vanadium based membrane to a metallic connection section comprising: mounting a section of a vanadium based membrane on a connector formation of a connection section, the connection section being formed of a different metal to the vanadium based membrane, the connector formation providing a recess into which a section of the vanadium based membrane is seated and a connection interface in which the end face of the vanadium based membrane is proximate to or substantially abuts an adjoining face of the connector formation; mounting and operating a chiller arrangement in thermal contact with vanadium based membrane proximate the connection interface; heating a filler metal on the connection section to at least the liquidus temperature of the filler metal using a laser beam directed onto the filler metal located on the connection section and having a beam edge positioned at an offset location spaced apart from the connection interface a distance that attenuates direct heating of t

Abstract: The control panel and display of a cart-borne ultrasound system are support by a lift which can be controlled to allow the control panel and display to be raised, lowered, and rotated. The lift has a first pivot elbow mounted to the ultrasound system cart and a second pivot elbow on which the control panel and display are mounted. A four-bar linkage is coupled between the pivot elbows which enables to control panel and display to be raised and lowered while maintaining the inclination of the control panel. The pivot elbows allow the control panel and display to be turned and rotated. A pair of hydraulic struts are mounted to the four-bar linkage to support the weight of the control panel and display. When a control button on the handle of the control panel is depressed the control panel and display can be freely raised, lowered and rotated. When the control button is released the pivot elbows and four-bar linkages are locked in their current positions.

Abstract: The control panel (14) and display (16) of a cart-borne ultrasound system (10) are support by a lift (30) which can be controlled to allow the control panel and display to be raised, lowered, and rotated. The lift has a first pivot elbow (70) mounted to the ultrasound system cart and a second pivot elbow (70) on which the control panel and display are mounted. A four-bar linkage is coupled between the pivot elbows which enables to control panel and display to be raised and lowered while maintaining the inclination of the control panel. When a control button (26) on the handle (24) of the control panel is depressed the control panel and display can be freely raised, lowered and rotated. When the control button is released the pivot elbows and four-bar linkages are locked in their current positions.

Abstract: A query phrase may be automatically classified to one or more topics of interest (e.g., categories) to assist in routing the query phrase to one or more appropriate backend databases. A selectional preference query classification technique may be used to classify the query phrase based on a comparison between the query phrase and patterns of query phrases. Additionally, or alternatively, a combination of query classification techniques may be used to classify the query phrase. Topical classification of a query phrase also may be used to assist a search system in delivering auxiliary information to a user who entered the query phrase. Advertisements, for instance, may be tailored based on classification rather than query keywords.

Abstract: An example method for reviewing documents includes scoring documents using an artificial intelligence model, and selecting a subset of highest scoring documents. The method further includes inserting a number of randomly-selected documents into the subset of highest scoring documents to form a set of documents for review, wherein a reviewer cannot differentiate between the randomly-selected documents and the subset of highest scoring documents included in the set of documents for review, and presenting the set of documents for review by the reviewer.

Abstract: A system for controlling a roller shade having a roller tube windingly receiving a shade fabric varies roller tube rotational speed for constant linear shade speed. The desired linear shade speed, roller tube diameter and shade fabric thickness and length are stored in a memory for use by a microprocessor. Preferably, the roller tube rotational speed is varied by the microprocessor depending on shade position determined by signals from Hall effect sensors. The microprocessor maintains a counter number that is increased or decreased depending on direction of rotation. Based on the counter number, the microprocessor determines shade position and a corrected rotational speed for the desired linear shade speed. Preferably, the microprocessor controls roller tube rotational speed using a pulse width modulated signal. The system may be used to control first and second roller shades having roller tubes of differing diameters or shade fabrics of varying thicknesses.
