Abstract: The invention relates to a method for detecting bad pixels from a pixel array of a device, for capturing an image, that is sensitive to infrared radiation. The method includes: receiving an input image captured by the pixel system, and calculating a score for a plurality of target pixels including at least some of the pixels from the input image. The score for each target pixel is generated on the basis of k pixels of the input image that are selected in a window of H by H pixels around the target pixel. H is an odd integer greater than or equal to 3, and k is an integer between 2 and 5. Each pixel, from the set formed of the k pixels and the target pixel, share at least one border or corner with another pixel from said set, and the values of the k pixels are at respective distances from the value of the target pixel, the k pixels being selected on the basis of the k distances. The method also includes detecting that at least one of the target pixels is a bad pixel on the basis of the calculated scores.

Abstract: A device comprising a hardware processor and memory storing an application of an application package comprising a first version and a second version of the application, the first version being intended to be executed on a genuine device and the second version on a jailbroken device. The hardware processor determines a jailbreak status of the device, i.e. genuine or jailbroken and derives a key based on at least the jailbreak status.

In case the jailbreak status is jailbroken, the hardware processor deciphers using the key at least a first part of the second version and executes the second version using the second deciphered part, for example comprising executable instructions.

Abstract: A network monitoring and network congestion analysis can be performed based on a comparison of data packets at multiple different network nodes installed at different locations on a communication path. A downstream network node may be installed at a user location while an upstream network may be installed at an access router further up the network. A network congestion analyzer may receive data packet information including timestamps from both network nodes, and may compare the data packet information to group the data packets into application flows and match the corresponding packets from the different network nodes. Based on the data packet matching, the network congestion analyzer may calculate packet loss, packet delay, packet delay variation, and perform other network congestion analysis techniques for the application flows corresponding to a user's various devices and the applications executing on those devices.
