Abstract: A steam generating system in an oven includes an external housing which encloses an oven chamber, a hot air channel where hot air is about to flow and a hot air inlet in the form of a series of openings in the wall of the oven chamber through which hot air is blown into the oven chamber, an exhaust outlet via which hot air is removed from the oven chamber and a door. The steam generating system includes a control unit adapted to control a baking or cooking procedure by generating control signals, and an elongated steam generating module horizontally arranged in the hot air channel, the steam generating module being rotatable along a longitudinal axis and including steam module elements. Each steam module element is elongated and includes one main surface provided with a generally flat extension, the steam generating elements are arranged in parallel above each other.

Abstract: In an object oriented computer system, a framework mechanism defines behavior that may be accessed by different processing levels in the framework. A shared policy corresponding to the behavior is defined. A policy usage view is defined that includes one or more methods for accessing attributes required by the shared policy. A view adapter is also defined that provides an implementation for invoking the methods on the policy usage view. When a processing level needs the behavior defined by the shared policy, the methods on the view adapter are invoked, which retrieve the required attributes for the shared policy.

Abstract: In an object oriented computer system, a framework mechanism defines an infrastructure for allowing a user to couple processes in the framework together in any suitable way to define a desired process flow. A user first defines a static object structure that corresponds to the specific process flow from one process to the next. The processes in the framework may be flexibly coupled in any suitable order, so a process does not have knowledge of its predecessor or successor processes. Thus, at run-time, a process determines the next step in the process flow from the static object structure. Once a process determines its subsequent process, a client may then create the next process and invoke methods on one or more objects corresponding to the newly-created process. Each process thus determines at run-time the next step in the process flow from the static object structure that the user statically defined to configure the process flow, which defines the desired processing environment.

Abstract: The present invention relates to a method for comparison between a first optical signal (.PHI..sub.1) and at least one other signal. The invention can for instance be used for image recognition. In this application it is a problem to be able to perform parallel processing of the content of an image. This problem among others is solved in connection with the invention by illuminating a MIS-structure (11; FIG. 1) with the first optical signal (.PHI..sub.1), which creates an optically induced change in the surface potential of the MIS-structure and by influencing the surface potential also by said at least one other signal by illuminating the MIS-structure (11; FIG. 1) with a second optical signal (.PHI..sub.2) or by applying the signal in the form of a voltage across the structure or by providing the structure with charge in the insulator or its interfaces or by a combination of these methods and by varying at least one of all signals as a function of time.

Abstract: An optical measuring apparatus for measuring force or pressure, having at least one light source, at least one optical fiber for passing light from and to a sensor, and one detector system. The sensor includes a material having pressure- and force-dependent photo luminescence properties, the signal received in the detector system being dependent on the pressure or the force applied to the sensor.

Abstract: The invention relates to a device for measuring current which traverses a light-emitting structure, the current passage thus causing emission of light. It is characterized in that the emitted light signal is adapted to be supplied to two photo-detectors having different sensitivity spectra and/or with at least one photo-detector being provided with an optical filter. The output signals of the photo-detectors are adapted to be supplied to a quotient forming member and/or a calculating member for obtaining a signal which is compensated for temperature variations in the light-emitting structure and other sources of error.

Abstract: A fiber-optic temperature-measuring apparatus which monitors the photo-luminescence of a body of solid material subjected to the temperature to be measured. Exciting radiation is conducted by means of at least one optical fiber towards a material with temperature-dependent luminescence which is in optical contact with the fiber, whereby luminescence occurs. The radiation emitted as a consequence of the luminescence is transmitted via at least one optical fiber from the body to a place of measurement, where a measure of the temperature may be obtained. The luminescent body may consist of a semiconductor material.

Abstract: A fiber optical measuring device for measuring a magnetic or electric field comprises an optical modulator influenced by the field. The optical properties of the modulator are dependent on the magnetic or electric field acting on the modulator. The optical property which is made use of is the field dependence of at least one absorption edge of the radiation absorption spectrum of the modulator material. Optical fibers may be used for feeding light into the modulator and for leading away light that has passed through the modulator.

Abstract: A device for compensating temperature dependent volume variations in a closed pressure medium system where at least two variable volume members are connected via a pipe to each other for transfer of movement between each other. At least one of the movement transmitting members has two ends freely movable relative to the pipe. One of the ends cooperates with a support, the position of which varies with the temperature as the volume of a flexible means, which is rigidly attached to the pipe, changes. The other end of the movement transmitting member is freely movable relative to the flexible means.
