Patent SE-0101333-L (SE)
Inventor: SCHOEPS KNUT CHRISTIAN
IPC: B25B23/14
Filed: 2001-04-17
Abstract: A method and a device for determining the torque magnitude transferred to a threaded fastener at each one of a series of torque impulses delivered to the fastener, includes application of repeated torque impulses on the fastener by a power tool having a motor with a rotor and a pulse unit which intermittently couples the motor to an output shaft. The pulse unit includes an inertia drive member which is accelerated by the motor and transfers its kinetic energy to the output shaft at each torque impulse. A rotation detecting device indicates the instantaneous rotation movement of the inertia drive member. At each impulse generation, the inertia drive member is retarded, and the retardation magnitude as a function of time is calculated. The product of the retardation magnitude and the total inertia moment of the drive member and other rotating parts of the tool forming a rigid unit with the inertia drive member reflects the torque magnitude transferred to the fastener at each impulse.

Abstract: An interactive method of presenting information in an image to a user, who carries a head-mounted display device that presents an image of the surroundings. The user's head position and direction are established in relation to the surroundings and a calculating device establishes, based on this, which part of the surroundings is positioned in front of the user's head. Furthermore, the calculating device establishes where in a chain of information the user is positioned and, based on this, presents information in the form of a virtual image which is mixed with the real image. A central part of the image is then defined and fields and/or objects outside this area are shown in a non-disturbing way until the user's gaze has left the central part. The user informs the calculating device that he/she has received the information and, respectively, performed the current operations by looking at the fields/objects.

Abstract: Inspection of micromask patterns occurs by both moving an inspecting laser beam relative to a micromask and varying the intensity of said beam in the same manner that occurs during pattern generation. The pattern modulates the inspecting laser beam by one of reflecting or transmitting a modulated laser beam therefrom. The modulated beam then is sensed and used to produce a modulation signal. The modulated signal is compared to a control signal, which controls both the relative movement between a writing laser beam and the micromask and varies the beam intensity during pattern generation. Agreement between the modulation and control signals indicates correct pattern generation and a difference therebetween indicates a pattern inaccuracy.
