  • Publication number: 20240106344
    Abstract: A wireless power-reception system has a bridge rectifier with two high-side and two low-side transistors, linked to input-nodes and sense-resistors. During a first phase, a control circuit activates certain transistors for rectification, producing an output voltage, while modulating a gate voltage of a non-activated low-side transistor to dissipate excess power and regulate the output voltage. During a first given number of occurrences of the first phase, the control circuit determines the current through the low-side transistor having its gate voltage modulated based upon a voltage across a first sense resistor coupled between that low-side transistor and ground. During a second given number of occurrences of the first phase, the control circuit determines the current delivered to the load based upon a voltage across the first sense resistor and a voltage across a second sense resistor coupled between the other low-side transistor and ground.

  • Publication number: 20240068783
    Abstract: A method to detect, identify and determine the position of laser points from infrared laser emitters in a firearm training simulation system. The method consists of two steps. This first step combines some common tools such as a camera with a filter switcher and edge and corner detecting algorithms in image processing to provide a fast automatic screen calibrating method. The second step is to detect laser point objects in each frame continuously captured by the camera, and then further process these objects to identify laser shots, filter out noisy objects, and eventually detect simulated shots from different laser emitters and determine the final mapped position of the shot.

  • Publication number: 20230246829
    Abstract: A client device that is not originally compliant with a particular security standard (e.g., FIPS) is brought into compliance through the addition of a standard-compliant software-based cryptographic library. In order to adapt the cryptographic library to integrate with the hardware-backed keystore, a non-hardware-backed software keystore is used to store keys used by the cryptographic library. Additionally, in order to provide appropriate security for the software keystore, the software keystore (and/or the keypairs within the software keystore) is protected by a password, and the password is in turn protected by the hardware-backed keystore. Thus, to obtain the password needed to obtain a keypair from the software keystore that is in turn needed to use the cryptographic library, a user must authenticate with the operating system, e.g., by providing biometric credentials.

  • Patent number: 10148671
    Abstract: A functional program stored in a memory area of an electronic card may be protected against an attack by disturbance of electrical origin intended to modify at least one logic state of at least one code of this program. The method may include: a storage step during which codes of the functional program and codes of a check program intended to check the logical behavior of the functional program are stored in the memory of the card; and a step of executing at least one code of the functional program followed by a step of checking the logic states of the functional program by executing the check program. During the storage step, the codes of the check program are stored in a memory area formed by addresses that are defined so that the attack by disturbance of electrical origin has no influence on the logic states of this program.

The masking (MSK) of said data includes a linear encoding step such as x?=x·L+c, in which x is the data to be masked, x? is the corresponding masked data, c is a code word included in a linear code C, and L is a matrix made up of linearly independent vectors not included in the linear code C. The invention also relates to a device (SC) implementing such a method.

  • Patent number: 9332156
    Abstract: In one example, a method for glare and shadow mitigation by fusing multiple frames includes illuminating the target with light from a first illumination direction and capturing a first frame of the target with a camera while the target is illuminated in the first illumination direction. The method also includes illuminating the target with light from a second illumination direction and capturing a second frame of the target with the camera while the target is illuminated in the second illumination direction. The first frame and second frame are fused together to form a composite image that simultaneously mitigates glare and shadow areas.

  • Patent number: 7580235
    Abstract: Systems and methods for presenting information corresponding to circuit breakers and for controlling such circuit breakers are disclosed. In one embodiment, the system can include a menu-driven, pointer-accessible graphical user interface via which an operator can receive information corresponding to circuit breakers, and can automatically change the states of the circuit breakers. Menus of circuit breaker information can be organized by the state of the circuit breaker, the location of the circuit breaker, the bus to which the circuit breaker is coupled, the electrical system to which the circuit breaker belongs, and/or the system or subsystem of which the circuit breaker is a part. In further embodiments, the circuit breaker information can be organized according to custom-made arrangements.
