Abstract: A pickup mechanism for feeding of weld pins from a magazine to a welding electrode of a welding gun, where the pickup mechanism is attachable to the welding gun in connection to the welding electrode, and where the magazine is attachable to the pickup mechanism, the pickup mechanism comprises a movable pickup lever arm displaceable between a pickup position and a delivery position, where the pickup lever arm is adapted for displacing the weld pin from a pickup position in the magazine to a welding position at the welding electrode; wherein the pickup lever arm has a pickup part comprising a feeding portion for feeding the weld pins from the pickup position to the welding position, where the pickup part comprises a retrieving portion arranged with a sliding surface for displacing the pickup lever arm in a direction essentially perpendicular to the direction of the movement between the delivery position and the pickup position when the sliding surface is in contact with a first weld pin in the magazine, and whe

Abstract: A user interface for a tactile feedback endoscopic simulation comprising an instrument (5) having a tubular member (8), a frame (10), a support arrangement (11), being rotatably arranged in relation to the frame, and being arranged to receive the tubular member along an axis A by two friction wheels (19a, 19b) in frictional contact with opposing sides of the tubular member. The user interface further comprises a force sensor, detecting force between the support arrangement and the frame,and a controller (9) arranged to receive a desired tactile feedback from said computer system and a sensor signal from said force sensor representative of an applied force, and arranged to control an actuator to operate said friction wheels to provide said desired tactile feedback. The system can provide a resistance more closely corresponding to the resistance felt during actual surgery, down to no resistance or even a pull on the instrument.

Abstract: A user interface device (1) comprising a frame (11) with a support (15) and a suspension portion (16) rotatable around a first axis (A). Further comprising a camera simulator (10) having a rigid shaft (21) with a primary extension along a longitudinal axis (C), being suspended by the suspension portion (16) so that it can translate along the longitudinal axis (C). A first rotational sensor (25) arranged to detect rotation of the suspension portion (16) around the first axis (A) by a guiding surface (18a) arranged at a distance from the first axis (A), and a first roller (30) arranged between the axis (A) and the guiding surface (18a) to rotate when the suspension portion (16) is rotated around the first axis (A) wherein the first rotational sensor (25) is arranged to detect rotation of the first roller (30). This solution enables satisfactory measured resolution at more reasonable price.

Abstract: A haptic user interface device (1) for a surgical simulation system (2), comprising a frame (11) having a fixed base (12), a neck portion (15) rotatable around a first axis (A) in relation to the base (12), and a suspension portion (16) rotatable around a second axis (B) in relation to the neck portion (15), an instrument (10) having a rigid shaft (21) suspended by the suspension portion (16) so as to be pivotable around the first axis (A) and the second axis (B), a first and second actuator (14, 17) mounted on the frame (11) and arranged to provide force feedback to a user when rotating the instrument (10) around the first axis (A) and the second axis (B). The first and second actuators are mounted on the neck portion (15).

Abstract: A handle for a hand held engine powered tool may include at least one lever or button for controlling the tool. The handle is made of at least two handle sections joined together. The lever or button for controlling the tool is however only secured in one of the handle sections in order to reduce the required grade of precision between the handle sections without affecting the performance of the lever or button.

Abstract: A method of verifying the strength of a vehicle in combination with auxiliary equipment fitted includes steps in which the vehicle chassis number or specification number are specified so that the vehicle specification and its parameters can be collected in a vehicle database, the parameters of the auxiliary equipment are specified, and a strength calculation for the vehicle is performed, based on the parameters of the vehicle and auxiliary equipment. In this way an assessment whether a reinforcement is needed when auxiliary equipment is fitted to a vehicle can be made.

Abstract: Handle (11) for a hand held engine powered tool comprising at least on lever or button for controlling the tool. The handle (11), and the tool fuel tank placed inside the handle, is made of at least two handle sections joined together. The levers or buttons for controlling the tool is however only secured in one of the handle sections (15, 16) in order to reduce the required grade of precision between the handle sections (15, 16) without affecting the performance of the levers and buttons.

Abstract: An antenna amplifier utilizes integrated dual duplex filters having a first filter branch for allowing through a transmitter band (Tx) between an uplead and an antenna, a second filter branch (Rx1) for allowing through a receiver band (Rx) from the antenna to an output element (3), a third filter branch for allowing through the receiving band (Rx) from an input element (4) to the uplead, and a low noise amplifier whose input is connected to the output element and whose output is connected to the input element. The low noise amplifier (LNA) is preferably both constructed and connected by means of filter-technical and circuit board-technical methods.
