The pocket echocardiograph: a useful new tool?
AIMS Hand-carried ultrasound scanners are getting smaller. The Acuson P10 is the latest and smallest portable echocardiograph available on the market. METHODS AND RESULTS We tested the ability of this scanner to allow qualitative assessment of LV size and function in an unselected group of 30 patients [19 male, 11 female; mean age (SD) 64.7 (10.3) years] seen by a consultant cardiologist (acc...
متن کاملA Concept Mapping Tool for Pocket PC Computers
A Handheld Learning Resource (HandLeR) is a prototype personal handheld computer designed to support personal learning projects (Sharples, Corlett, & Westmancott, Forthcoming). The proposed device will be in constant network communication. It will provide tools for learners to capture, organise and share context specific multimedia objects such as notes, sounds and images. It will support field...
متن کاملPOCKET: A tool for protecting children's privacy online
a r t i c l e i n f o Children's privacy in the online environment has become critical. Use of the Internet is increasing for commercial purposes, in requests for information, and in the number of children who use the Internet for casual web surfing, chatting, games, schoolwork, e-mail, interactive learning, and other applications. Often, websites hosting these activities ask for personal infor...
متن کاملHandling Tool Holder Collision in Optimal Tool Sequence Selection for 2.5-D Pocket Machining
Significant cycle time saving can be achieved in 2.5-D milling by intelligently selecting tool sequences. The problem of finding the optimal tool sequence was formulated as finding the shortest path in a single-source single-sink directed acyclic graph. The nodes in the graph represented the state of the stock after the tool named in the node was done machining and the edges represented the cos...
متن کاملSelecting an Optimal Tool Sequence for 2.5D Pocket Machining while Considering Tool Holder Collisions
Milling using a sequence of tools has become very attractive with the advent of rapid tool change mechanisms in modern CNC machines. However, the commercial CAM systems used to generate G&M code rely on experienced process planners to select a good tool sequence. When a tool sequence is selected and tool paths are generated, NCverify systems are used to check the tool paths for tool holder coll...
