- Fig. 1 a shows an example of a prior art mobile cellular telephone 10 comprising an engine assembly 12 enclosed by a removable rigid plastic front cover 14 and a removable rigid plastic back cover 16.
- the front cover 14 is illustrated in a part-open position, to reveal the engine assembly 12.
- a loose keypad 18 overlies keyboard switches 20 (key domes) of the engine assembly 12 and is held is place by the rigid plastic front cover 4 in the assembled telephone.
- the components of the prior art telephone 10, and the engine assembly 12 in particular, are schematically illustrated in Fig. 2.
- the engine assembly 12 is in physical connection with the keypad 18 as shown by arrow A.
- the engine assembly 12 includes a plurality of keyboard switches 20 which are electrically connected to a processor 22.
- the processor 22 is electronically connected a SIM card 26, to a display 28, and to a memory 30 and is also connected to a battery 34 for power distribution to other circuitry.
- Radio transceiver circuitry 32 for communicating in a cellular communications network is also electrically connected to the processor 22.
- An audio part 34 which is also electrically connected to the processor 22, provides an electrical signal to a speaker 36 and receives an electrical signal from a microphone 38.
- Fig. 1 b shows an alternative design of covers 14, 16 for the telephone
- the rigid plastic back cover 16 is permanently attached to the engine assembly 12 and is not removable.
- the rigid plastic front cover 14 is removable and a loose keypad 18 is located between it and the engine assembly 12 when the telephone 10 is assembled.
- the rigid plastic covers 14 and 16 are three-dimensional and provide a recognisable shape to the telephone. They additionally may protect the engine assembly 12 against damage and water ingress and are easily made by injection moulding. For these reasons rigid covers, and plastic covers in particular, are substantially universally used to enclose the engine assembly 12.
- a hand-portable device in the form of a mobile cellular telephone 10 according to a first embodiment of the invention.
- the hand portable device is a mobile telephone, in other embodiments it may be another type of device such as a personal digital assistant (PDA).
- PDA personal digital assistant
- the telephone 10 includes an engine assembly 12 as in the prior art telephone, the engine assembly 12 not being illustrated in any detail in Figs 3a to 4b.
- the engine assembly 12 is encased between a front cover part 14 and a back cover part 16.
- the cover parts 14 and 16 are shaped to fit snugly around the engine assembly 12, sandwiching the engine assembly 12 between the two cover parts.
- the front cover part 14 includes a main body portion 40, which in use overlies the front of the engine assembly, and a perimeter portion 42 which extends around an edge of the body portion 40.
- the perimeter portion 42 includes a flange 44 extending downwardly from the body portion 40 in normal use and an in-turned lip 46 extending inwardly from the flange 44.
- An elongate recess 45 is thereby defined between the lip 46 and the body portion 40, the recess 45 extending right around the perimeter portion 42 of the front cover 14.
- the flange 44, lip 46 and recess 45 form part of a closing arrangement as described in more detail below.
- the back cover part 16 also includes a body portion 41 which in use overlies the back of the engine assembly, and a perimeter portion 43 extending generally around an edge of the body portion.
- the back cover part 16 further includes a polymer actuator 50 which extends around the perimeter portion 43.
- the polymer actuator 50 also forms part of the closing arrangement, as described below.
- the polymer actuator 50 includes an electroactive, electrically conductive polymer 54, in the shape of an elongate, endless loop extending around the perimeter portion 42 of the cover part 14.
- the polymer actuator 50 further includes a solid electrolyte 52, also in the shape of an elongate endless loop, and a metal electrode 56, the electrolyte 52 being sandwiched between the metal electrode 56 and the conductive polymer 54 (which also functions as an electrode).
- the conductive polymer 54 and the metal electrode 56 are connected to a DC voltage source 58 such that a voltage may be applied to the polymer actuator 50.
- the polymer actuator 50 may be controlled by the selective application of voltage to alter its configuration.
- the configuration may be altered between a first configuration illustrated in Figs. 4a and 4b and a second configuration illustrated in Figs. 3a and 3b.
- the alteration of the configuration of the polymer actuator 50 is caused by the doping / dedoping of anions inside the polymer chain of the conductive polymer 54.
- the charge state of the conductive polymer may be stopped at any level of charging and keep that state without the application of a voltage being necessary.
- the polymer actuator 50 is therefore bistable, i.e. stable in either its first or second configuration, without the application of any voltage.
- a suitable material for the conductive polymer is polyrrole, polyariline or polythiothene.
- the metal electrode may comprise gold.
- the front and back cover parts 14, 16 of the telephone 10 function as follows. Initially, the voltage source 58 is used to apply a voltage with a given polarity to the polymer actuator 50, which therefore shrinks into the configuration illustrated in Figs. 3a and 3b. With the polymer actuator 50 in this configuration, the front cover part 14 may be brought into contact with the back cover part 16, with its flange 44, including the lip 46, passing by the polymer actuator 50. The lip 46 then contacts an outermost part 60 of the back cover part 16. Once the front cover part 14 is in this position, the voltage source 58 may be caused to apply voltage with an opposite polarity to the polymer actuator 50. The conducting polymer expands (in the plane of Fig.
- the polymer actuator 50 thereby entering the recess 45 formed between the body portion 40 of the front cover part 14 and the lip 46.
- the front cover part 14 is prevented from being removed from the back cover part 16 and the engine assembly is therefore firmly enclosed within the cover parts 14 and 16.
- the polymer actuator 50 may be altered between first and second configurations, causing the closing arrangement to be altered between a first condition in which the cover parts 14, 16 are retained on the engine assembly . 12 and a second condition in which at least one of the cover parts may be removed from the engine assembly.
- the polymer actuator 50 is relatively flexible, and its flexibility allows it also to form a substantially watertight seal between the front and back cover parts 14, 16, thereby protecting the engine assembly from water ingress.
- Figs. 5a to 6b illustrate an alternative embodiment of the invention in which equivalent components are given the same reference numerals as in Figs. 3a to 4b.
- This embodiment is generally similar to the previous embodiment except that the polymer actuator 50 in this embodiment is formed as four separate actuator elements 50a to 50d each including a conducting polymer 54, a solid electrolyte 52 and an electrode 56.
- the polymer actuator moves between the configuration illustrated in Figs. 5a and 5b, in which the front cover part 14 may be removed from the back cover part 16, and the configuration illustrated in Figs.
- each polymer actuator element 50a and 50d causes the polymer actuator element to move between a substantially straight configuration and a curved configuration in which it engages in the recess 62.
- the selective actuation of the voltage source 58 to alter the configuration of the polymer actuator 50 and allow the cover part to be removed may be caused for example by a user inputting a PIN or other security code.
- disassembly could be triggered from an external device or via a network and therefore could be triggered automatically, for example, in the event of the telephone being stolen.
- the disassembly may also be automatic, for example when disposing of the telephone, and the polymer actuator could be operated in such a way that it pushes the parts away from each other.
- the telephone could be prevented from operating with its cover part in the disassembled condition.
- the polymer actuators may allow shielding integration into the covers.
- EPAM actuators such as electrostrictive polymer artificial muscle (EPAM) actuators.
- An EPAM actuator has a performance which is similar to that of natural muscle.
- a non- conductive polymer such as, for example, silicone rubber (polydimethylsiioxane) or polyurethane is sandwiched between compliant electrodes.
- the compliant electrodes may comprise powdered graphite which is brushed onto the polymer through a stencil or may comprise a polymer filled with very fine conductive particles, such as carbon black, although this adds some stiffness.
- These conductive polymer materials are applied by spraying or dipping.
- the thickness of the polymer between the electrodes should be uniform, in order to keep the electric field constant throughout the polymer and avoid areas where electrical breakdown may occur.
- the polymer may comprise a film which may be fabricated by spin coating .
- RFID tags may be incorporated into the cover parts allowing information about the cover parts to be "read” by the closing arrangement, allowing the polymer actuators to be positioned differently for respectively different cover parts.
- the cover may have multiple parts and one or more of the parts may be attached to the engine assembly or to another cover part, using polymer actuators.
- the polymer actuator(s) expand into a recess in order to retain the cover part in place.
- expansion of the polymer actuator in a particular dimension could push the cover part out of engagement with another cover part or the engine assembly, to release the cover part.
