1 The Technology Partnership plc +44 1763 262626 www.ttp.com A Picture speaks a thousand words… The patent specification Current Search Evaluation of retrieved patents Image search solutions Future search Jane List 8th November 2007 IRF Symposium, Vienna.

2 The Patent specification 200 and 1,000,000 Hz. 300 and 20,000 Hz.

3 search strategies for subject searches Classifications IPC8F28D15/02(heat pipes) ECLAF28D15/02F (flexible heat pipes ) USPTO165/272(heat pipe heat transfer characteristics) JP FIF28D15/02E(using circulation type heat pipes) JP F Term3L106(heat exchangers using int. heat conductive media) ______________________________________________________________________ Keywordssynonyms, concepts, terminology Search operatorsboolean, proximity Statistical tools ranking, find similar Semantic analysisanalysis of sentence, word frequency,

4 Evaluation of search results A shape memory alloy actuator comprising a body (1) connected through an arm (5) with an activating member (15), the body (1) being arranged for rotation around a pivot (2) and connected to a first wire (9) and a second wire (10) of a shape memory alloy such as nitinol and to a biasing means such as a tension spring (6) such that heating and therefore shortening of the wire (10) rotates the body (1) counter-clockwise such that the tension spring (6) is in its cocked position while heating (shortening) of the wire. US2004-068985 SMA Pump: wire SMA; spring biased Key: SMA blue, bias purple

5 Evaluation of search results A slider 13 is coupled to a pair of shape memory alloy wires 1 and 2 therebetween. A machine spring 3, having a set load being an intermedi ate value between a load under the high temperature state and a load under the low temperature state of the shape memory alloy wires 1 and 2, is coupled to either of the shape memory alloy wires 1 and 2. After the one shape memory allow wire 2 is heated and the other shape memory alloy wire 1 is cooled, and when, conversely, the shape memory alloy wires are cooled and heated, a delay in the cooling speed of the shape memory alloy wire 2 being cooled is compensated through expansion of the machine spring 3. JP61-171885 SMA Pump: Spring SMA; Spring biased
