  • Publication number: 20240135691
    Abstract: Methods, systems, and apparatus for obtaining input features representative of a region of space, processing an input comprising the input features through the ML model to generate a prediction describing predicted features of the region of space, obtaining result features describing the region of space, determining a value of at least one evaluation metric that relates the predicted features and the result features, that at least one evaluation metric including one of a distance score, a pyramiding density error, and min-max intersection over union (IOU) score, and training the ML model responsive to the at least one evaluation metric. Other implementations of this aspect include corresponding systems, apparatus, and computer programs, configured to perform the actions of the methods, encoded on computer storage devices.

  • Publication number: 20240045946
    Abstract: A monitoring device for verifying the integrity of a software of a memory device is disclosed. The monitoring device comprises a processor and a memory, the memory containing instructions executable by the processor, such that the processor is to; receive first information on at least one physical side-effect of a computer apparatus as a result of an instruction of a monitored software being executed by the computing apparatus. The processor is also to receive second information on the monitored software being executed, and based on the first information and the second information, the processor is to determine if the monitored software is compromised.

  • Publication number: 20240036088
    Abstract: An example computing device comprises a memory storing software, and a processor to, identify an expected parameter value range of a plurality of expected parameter value ranges of a hardware component of the computing device, the expected parameter value range corresponding to a set operating mode of the hardware component; compare an analog parameter value of the hardware component to the identified expected parameter value range; and determine whether the analog parameter value is within or outside the expected parameter value range.

  • Publication number: 20240028710
    Abstract: A method of determining whether a processing unit is compliant with a security policy is provided. The method may comprise obtaining first data indicative of a power consumption profile of the processing unit for a first time period, the power consumption profile comprising a variation of power consumption with time. The method may comprise determining whether the processing unit is compliant with the security policy during the first time period depending, at least in part, on the obtained first data. It may be that the processing unit complying with the security policy gives rise to a power signature in the power consumption profile of the processing unit during a period of compliance.

  • Patent number: 10934886
    Abstract: The present invention concerns a method (200) for managing a breakdown of a starter valve of a starting circuit of an aircraft turbine engine, comprising the following steps: —starting (203) the turbine engine, a state-change command being sent to the starter valve in order for it to open; —increasing (204) the engine speed of the turbine engine to a predefined first threshold, —during said increase (204) in engine speed, —if a difference in position has been detected (201) between the position sensors before the step of starting the turbine engine or if a difference in position is detected (205) between said position sensors, determining (207) the position sensor that has switched between the closed position and the open position, the other position sensor having remained in the open or closed position; —when the first threshold is reached, storing (209) the position sensor that has switched between the closed position and the open position as healthy and the position sensor that has remained in the open or

  • Publication number: 20150205862
    Abstract: Method and device for recognizing and labeling peaks, increases, or abnormal or exceptional variations in the throughput of a stream of digital documents. The invention relates to a method and a device which make it possible to produce an explanatory view of the variations in the throughput of a stream of documents, or to alert an operator by indicating the main subjects of the abnormal variations in said throughput. The device implements a method (1) of recognizing the periods during which the throughput of a stream of documents varies abnormally, a method (2) of morphologically analyzing text, a method (3) of determining, for a given period, the character strings of which the frequencies are the highest for the documents of the period, and a method (4) of building a label from the strings identified by said method (3). The device can be coupled to an alerting (23) or display (22) system. The method and the device according to the invention are particularly intended for social media monitoring.

  • Patent number: 8649954
    Abstract: A system for controlling angular position of stator blades including: a mechanism for calculating a set angular position of the blades according to one of speeds; and a module for correcting the set position including: a mechanism for determining the angular position of the blades; a mechanism for measuring fuel flow rate of the turbine engine; a memory unit in which consecutive angular positions of the blades are combined with the fuel flow rates of the turbine engine measured at the angular positions; and a mechanism for determining a correcting angle according to the difference between the fuel flow rates measured between two consecutive angular position of the blades. A method for optimizing the common angular position can utilize the system.

  • Patent number: 6213344
    Abstract: The present invention relates to wet wipes (1) for use in wiping surfaces in the home and in industry, in addition to their use on the human body such as for baby wipes, make-up removal and other skin care applications. The wet wipes are folded and interleaved with one another (40, 50) to provide an improved stacking configuration whereby each wipe can be readily singly separated from the wet wipe stack by the consumer.
