Patent number: 11307635Abstract: 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.Type: GrantFiled: April 24, 2018Date of Patent: April 19, 2022Assignee: FINGERPRINT CARDS ANACATUM IP ABInventors: Peter Almers, David Carling, Rolf Sundblad, Nicholas Weiner, Benjamin Willcocks

Publication number: 20220091257Abstract: 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.Type: ApplicationFiled: January 24, 2020Publication date: March 24, 2022Applicant: Acconeer ABInventors: Peter Almers, Bo Lincoln, Rikard Nelander, David Montgomery, Gaston Holmén

Patent number: 11270544Abstract: 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.Type: GrantFiled: April 18, 2018Date of Patent: March 8, 2022Assignee: FINGERPRINT CARDS ANACATUM IP ABInventors: Olis Olofsson, Peter Almers

Patent number: 11204637Abstract: A method and a gateway system for enabling adaptive power management. The gateway system is powered by a rechargeable battery that is coupled with a solar power source. A location reading indicating a location of the gateway system is transmitted at a first time. A solar profile is received from a management server. The solar profile indicates a measure of power expected to be generated at the location during an interval of time that occurs after the first time by the solar power source. The gateway system determines based on a current battery level of the rechargeable battery and the solar profile an optimal power usage plan for the gateway system and operates according to the optimal power usage plan during the interval of time.Type: GrantFiled: March 5, 2021Date of Patent: December 21, 2021Assignee: Samsara Networks Inc.Inventors: Brian Tuan, Kavya U.
