Abstract: The invention relates to measuring climate inside a longitudinal cavity of a structure from two or more positions. The cavity has two ends that may be ends open to a surface of the structure, or closed ends inside the structure, or a building comprising the structure. The climate is measured by an arrangement inserted to the cavity. The arrangement comprises plurality of interconnectable sections. The sections comprise at least one sensor section and one or more extension sections. The at least one sensor section and one or more extension sections are interconnectable in a series for insertion inside the cavity. The at least one sensor section is configured to measure at least one quantity indicating the climate. The one or more extension sections are configured to position the at least one sensor section from at least one of the ends of the cavity to a measurement position within the cavity.

Abstract: A water and/or airtight electrical socket for portable electronic devices includes sealing elements that are shaped like an arc, and arranged to seal only a portion of the perimeter of the socket-plug interface. When this arc element experiences pressure, it will mechanically relay the force caused by the pressure only to that section of the perimeter of the socket-plug interface that it is arranged to seal. It will not relay mechanical forces any further. This way, the mechanical effect of any extra asymmetric pressure will simply be limited to increasing the pressure of the seal in the perimeter section of that particular sealing element, thereby tightening the seal further still. This allows the socket opening to be sealed in a water- and/or airtight manner even in asymmetric pressure conditions, both when there is no plug in the socket and also when a plug is inside the socket.

Abstract: The invention relates to an electrical socket (110) that is water and/or airtight. In particular, the invention relates to a water and/or airtight electrical socket (110) for portable electronic devices (500). The invention involves sealing elements (200, 210, 220 and 230) that are shaped like an arc, and arranged to seal only a portion of the perimeter of the socket-plug interface (300, 310). When this arc element experiences pressure, it will mechanically relay the force caused by the pressure only to that section of the perimeter of the socket-plug interface (300, 310) that it is arranged to seal. It will not relay mechanical forces any further. This way, the mechanical effect of any extra asymmetric pressure will simply be limited to increasing the pressure of the seal in the perimeter section of that particular sealing element (200, 210, 220 and 230), thereby tightening the seal further still.

Abstract: The present invention relates to a locking arrangement for a terminal device of a telecommunication system. To improve the operating reliability of the terminal device, the attachment and locking of the structural elements changeable by the user to the rest of the device structure is improved by a locking device which consists of a solid piece (100) to be fitted into the terminal device in the different places of the frame part of which one has formed separate spring-like locking elements, each of which functions as a locking device of some structural element of this kind of the terminal device. The first spring-like locking element (20) may e.g. be adapted to lock the accumulator of the terminal device to the accumulator space reserved for it, and the second locking element (40) to lock the smart card of the terminal device to the space reserved for it in the terminal device. In the same locking piece there may also be locking elements (30, 31) for locking the accumulator cover in place.

Abstract: The invention relates to the attachment of a mobile phone battery in which the battery (9) is pushed in the horizontal direction, for example in the direction of the surface of the phone, into a recess (2) formed in the casing (1) of the phone. The sides of the battery (9) are equipped with tabs (10, 10'), which slide under the tabs (5, 5') of the tabs on the sides of the recess (2) in such a way that these hold the battery in place in the vertical direction. Holding of the battery (9) in place in the horizontal direction is arranged with at least one locking element (12), which according to the invention is located on the side of the battery and locks, when viewed in the direction of pushing, behind the tab (5') on the side of the recess in such a way that the tab (5') functions as an element that holds the battery in place simultaneously in both the horizontal and vertical direction.
