Abstract:
An electrode (100) and electrodes for a biomedical system are provided. The electrode includes a backing pad (105) with top and bottom surfaces. A conductive element (110) is attached to the bottom surface of the backing pad, and a conductive gel layer (140) covers at least part of the bottom surface of the conductive element. A bonding layer (130) is disposed at least in part between the conductive element and the conductive gel layer. The electrode includes a leadwire (115) with a stripped end length (120), and at least a portion of the stripped end length is disposed between the conductive element and at least one of the bonding layer and the conductive gel layer.

Abstract:
A composite material made of borophosphosilicate and an organic matrix, used to create, preferably, a solid electrolyte membrane for a proton conduction electrochemical device having an operating temperature of up to 400 DEG C. The organic matrix consists of a thermally stable polymer. The polymer can, for example, be a polyimide.
Abstract:
A security device for a member; such as a door (11), displaceable between a closed and an open position, the device providing for the blocking of access to an operating means for the member, such as a handle or key entry, the device comprising: an anchorage member (20) mounting on the member (11) as aforesaid with the member in an open position, at a working location in the vicinity of the operating means; a padlock (30) for attachment to the anchorage (20), and a housing (40) for attachment to the anchorage by way of the pad lock when the anchorage is attached to the door in the working location so that housing extends to cover the operating means; the housing including-a recess (42) for to receive the padlock (30) so that the padlock is isolated shrouded by the housing; means for securing the padlock to the housing when the padlock is located in the recess; means (34, 44) for accessing an operating means, such as a key hole, for the padlock (30) when shrouded by the housing; to enable the padlock, when secured in the recess, to demountably retain the combined housing and padlock to the anchorage.
