Abstract:
The invention relates to a system for determining an angular speed of a flywheel of an internal combustion engine. At least two measurement points are defined on the flywheel and a measurement unit is configured to receive information from the sensor on detections, when each of the at least two measurement point arrives in detection space of the sensor and points of time of the detections are determined. Furthermore, a time difference of a first detection of a measurement point and a sequential detection of the same measurement point for each of the at least two measurement points and the angular speed of the flywheel in relation to each of the at least two measurement points is calculated at least party by means of the time difference. In this way, speed values are always determined on the basis of a full rotation, so that errors caused by a different or irregular angular spacing of the markers are avoided. The invention also relates to a method for determining the angular speed.

The fuel system further comprises an outer pipe (5) that is arranged around the fuel pipe (4) for forming a fluid volume between the fuel pipe (4) and the outer pipe (5), a source of inert gas (7), and means (6, 20) for introducing inert gas from the gas source (7) into the fluid volume between the fuel pipe (4) and the outer pipe (5).
Abstract:
A light guide system comprises a first element (201) that comprises a first reflective surface (203) for reflecting at least a part of a first portion of light emitted by a light source (202) and an opening (204) for constituting a passage for a second portion of the light. The light guide system further comprises one or more second elements (205a-205c) each comprising a second reflective surface (206a-206c) and being shaped to fit with the opening of the first element so that the second element is attachable to the first element for arranging the second reflective surface to reflect at least a part of the second portion of the light to a spatial area where the first portion of the light is directed to. Different light distribution patterns can be obtained by using different second elements together with the first element.
Abstract:
A medical or a dental instrument comprises an operative portion (101) for operations according to the purpose of use of the instrument, a center portion (103) mechanically connecting to the operative portion, and a radio frequency identifier (106) located on the center portion and capable of being read from a distance of the instrument. The instrument further comprises a tubular handle portion (104) provided to surround the radio frequency identifier and at least a part of the center portion, the tubular handle portion being cast on the instrument so that the material of the tubular handle portion is adhered to the material of the center portion. Thus, the tubular handle portion acts not only as the handle portion but also as at least a part of a fixation system attaching the radio frequency identifier to the instrument. An instrument of such construction is easy to keep hygienic.
Abstract:
A light guide (201) comprising a transparent element is presented. The transparent element comprises a first surface (203) for acting as a light-ingress surface and a second surface (204) for acting as a light-egress surface. The second surface comprises elevations (205) for directing a part of the light into directions sideward with respect to a direction in which another and greater part of the light exits the transparent element through the second surface. Each elevation is shaped to provide total internal reflection for a light beam on a first point of the surface of the elevation and refract the reflected light beam on a second point of the surface of the elevation so as to direct the light beam sideward. The sideward directed light enables an observer, who sees the light guide from a small viewing angle, to easily see whether the light is on or off.
