Abstract: The present invention relates to a method and an arrangement for a second individual having a context log which contains information about contextual aspects, related to the second individual, as a function of time, to read information from a first individual's context log which contains information about contextual aspects, related to the first individual, as a function of time.

Abstract: The present invention relates to a method and an arrangement for a first individual to report worked time based on his context log containing information about contextual aspects, related to the first individual, as a function of time. From information from the context log, a context graph of the first individual which shows contextual aspects as a function of time is generated, and at least a contextual aspect which refers to at least one location of the first individual and a contextual aspect which refers to at least one activity on a work- or individual-related objects with the same location as the first individual are included, and, for a task performed by the first individual during a certain period of time, a working account is selected, and, based on shown contextual aspects as a function of time, the period of time that is assessed to have been used for the task is marked in the context graph as allocated to the selected working account.

Abstract: A system is disclosed for counteracting work-related stress injuries in an individual person when working in connection with at least one work-related object which permits the adjustment or use of different working positions, the object being provided with at least device for detecting its current adjustment or working position and delivering a signal containing information on this to a computer. The information is recorded and stored together with information on the current time. The computer also includes a device for recording and storing information relating to pain symptoms experienced by the individual together with information on the current time. The system perferably also includes a graphic dialogue box connected to the computer for communication with the individual and in which the individual marks the position and intensity of pain symptoms experienced, following which this information is transferred to the computer.

Abstract: A target raising device for shooting practice having a target mountable on a transverse shaft rotatable by a motor, and containing a power unit, such as a battery, for driving the motor and a control unit, such as a radio receiver, for remote control of the motor, wherein the target raising device is supported by runners which are arranged along each longitudinal side of the device and which are curved up at the front and rear ends, and are curved back at the top to form carrying handles, whereby the position of the transverse shaft is close to the center of the curved parts of the runners at one end of the target raising device, so that as the target is raised or lowered rods which support the target and which are attached to the transverse shaft at right angles to it pass by the last named curved parts of the runners approximately at right angles to tangents of the curved parts, so that an object or part of a body accidentally interposed between the rods and the curved parts of the runners is carried along
