The disclosure relates to an autonomous moving object comprising: a radar sensor configured to scan a volume in front of the object, and a radar signal processor configured to: acquire a sequence of radar responses, each radar response of the sequence being acquired at a different position (P) of the autonomous moving object, and perform synthetic aperture radar processing of at least parts of the acquired sequence of radar responses to obtain a synthetic aperture radar image representing response amplitude as a function of at least distance and angle with respect to the radar sensor, the autonomous moving object further comprising: a controller configured to detect presence of a potential obstacle within a pre-defined sub-volume in front of the autonomous moving object by analyzing the synthetic aperture radar image and, in response to detecting presence of a potential obstacle, output a control command configured to cause a changed movement of the autonomous moving object.

Autonomous moving object

An autonomous moving object comprising a radar sensor is provided. The radar sensor is configured to, during movement, acquire data sets representing reflections from surface portions located within a distance range, and, at least at a sequence of occasions, illuminate a surface region and acquire a data set representing, for each of a set of distances within said distance range, an amplitude and a phase of reflected radar signals received from surface portions located at said distance. Said surface regions comprise common sub-region illuminated at each of said occasions. A radar signal processor is configured to receive the data sets acquired at each of said sequence of occasions. The received data sets form a collection of data sets, wherein each data set of said collection comprises a data subset pertaining to said common sub-region. A surface classifier processor is configured to output a classification of a surface type of the surface based on said collection of data subsets.

A method of controlling operation of a field-powered biometric device comprising biometric acquisition circuitry, processing circuitry controllable to transition between a first functional state having a first power consumption and a second functional state having a second power consumption lower than the first power consumption, and power management circuitry. The method comprises the steps of monitoring, by the power management circuitry, a property indicative of a supply voltage to the processing circuitry; controlling, when the monitored property indicates that the supply voltage has fallen to a first threshold voltage, the processing circuitry to transition from the first functional state to the second functional state; and controlling, when the monitored property indicates that the supply voltage has increased to a second threshold voltage higher than the first threshold voltage, the processing circuitry to transition from the second functional state to the first functional state.

The present invention relates to a method for progressively enrolling a user of a smart card, specifically applying a multi-step activation process for enabling fingerprint authentication for the smart card. The invention also relates to a corresponding smart card and to a computer program product. The present invention provides a solution for seamless fingerprint enrollment for a smart card user.

Method and smart card adapted for progressive fingerprint enrollment

A method for granting access for a user to a domain which is subject to an access restriction, wherein the user belongs to a group of one or more user shaving an access privilege in relation to the domain. The method comprises acquiring a first set of biometric data associated with the user. A first identification is successful if a comparison of the first set of biometric data to previously acquired data relating to the user, or to the group of users, indicates that the user belongs to the group. The method also comprises acquiring a second set of biometric data associated with the user responsive to the first identification being successful. A second identification is successful if a comparison of the second set of biometric data to previously acquired data relating to the user indicates that the user has the access privilege.

Access control for access restricted domains using first and second biometric data

The present disclosure generally relates to a method for authenticating a user by means of an electronic device, where the electronic device comprises a first and a second control unit adapted to process a biometric representation from a biometric sensor. Preferably, the second control unit comprises a secure element and/or a secure block adapted to provide a secure processing environment. The present disclosure also relates to a corresponding electronic device and to a computer program product.
