Abstract: The present invention relates to a sensor system for monitoring a powder handling device. The sensor system comprising an alternating electrical signal source electrically connectable to the powder handling device and a processing device. The processing device comprising a measuring device and a controller communicatively connectable to the measuring device. The controller is configured to receive measurement data from the measuring device and determine a phase difference between an input signal and an output signal based on the received measurement data.

Abstract: A rotary bearing with a damper having an inner bearing element configured for rotation around an axis of rotation, an outer bearing element coaxial with the inner bearing element, an inner damper element with an outer surface surrounding the outer bearing element, an outer damper element with an inner surface surrounding the inner damper element, at least one sealing element provided between the outer surface and the inner surface, the sealing element confining a damper space having a circumferential film space defined by a clearance between the outer surface and the inner surface. The damper space contains fluid and is a closed, isolated damper space.

Abstract: A method of incrementally enrolling a user's fingerprint onto a payment card includes authorising a predetermined number of transactions using the payment card with a non-biometric verification, such as a PIN, where the user presents their finger to an onboard biometric sensor of the payment card during each authorisation, and then generating a biometric template for the user's fingerprint using fingerprint data collected from each of the authorisations.

Abstract: A method of using a smartcard may include detecting possible fraudulent use of a biometric sensor embedded within the smartcard and restricting, but not preventing, subsequent use of the smartcard after the possible fraudulent use has stopped. The restriction may include one or more of not permitting the bearer to make an action that they would normally be permitted to make, requiring a higher authorization confidence score than would normally be required before permitting the bearer to perform one or more actions, and requiring the bearer to pass a secondary authorization step before permitting the bearer to perform one or more actions.

Abstract: A smart card 102 may include a processor for controlling operation of the smartcard, a biometric sensor for identification of an authorised user, and an accelerometer for sensing movements of the smartcard. The processor may be arranged to permit access to one or more secure feature(s) of the smartcard based on the movements sensed by the accelerometer and authentication of the user's identity via the biometric sensor.

Abstract: A smartcard having multiple operating modes. The smartcard may include a processor for controlling operation of the smartcard and an accelerometer for sensing movements of the smartcard, wherein the processor is arranged to switch between different modes of the multiple operating modes in response to the movements sensed by the accelerometer.

Abstract: A radial gas foil bearing extending along a rotation axis including a carrier element provided with an opening extending along the axis, further including at least one foil extending circumferentially along a radial inner side of the opening of the carrier element, wherein the foil is attached to the carrier element is provided. In order to enable an easy manufacturing as well as safe operation it is proposed to provide at least one radial through hole in the carrier ring, wherein at least one fixation section of the foil is formed to be inserted into the through hole, wherein the fixation section and the through hole are made such that fixation section becomes by insertion into the through hole accessible from radial outside of the carrier element to be fixed to the carrier element.
