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 device comprising a touch sensitive screen (6), a pointer element (62) on the touch screen, and at least one pointing means (8) which is capable of interacting with the touch screen. The device also comprises a detector for detecting an active mode of the pointing means (8), and means for making the pointer element at least partially invisible when an active mode of the pointing means is detected. The invention also relates to a method as well as to a system, a touch screen module, a computer program and a computer program product.

Abstract: A device comprising at least a touch screen and a keypad for providing input functions. The keypad is provided with a key lock operation comprising an active state and a inactive state. The active state is adapted to disable at least part of the input functions of the keypad, and the inactive state is adapted to enable the input functions of the keypad. The device also comprises a detector for detecting when a stylus is in proximity with the touch screen; and a key lock activator for setting the key lock into said active state when the detector provides indication of the proximity of the stylus.

Abstract: A portable electronic device, comprising: a housing having an open position and a closed position, a touch-sensitive input area, a data input device for interacting with the touch-sensitive input area and a data input device storage region for the data input device. The device also includes a system for alerting a user when the housing is in the closed position and the data input device is not positioned within the data input device storage region.

Abstract: The invention relates to a method and an apparatus for codeless GPS positioning. According to the method, the unit (2) to be positioned receives GPS signals from several satellites (4), the codes of the GPS signals are removed, and the extracted carrier signals are transmitted out from the unit (2) to be positioned for the purpose of determining the position and/or velocity of said unit (2) to be positioned. According to the invention, the carrier signal frequencies are detected by means of a phase-locked loop and the thus detected signals are transmitted in digital format out from the unit (2) to be positioned for the purpose of further processing.
