IPC: G06V20/58
Filed: 2021-01-18
Abstract: Means of detecting an obstacle to be avoided by a UAV. The UAV comprises at least one camera. A method of obstacle detection involves capturing an image 100 with the camera, producing a hazard map 108 corresponding to an array of regions of the capture image by detecting a plurality of points 102 in the image that define the location of image features and/or transforming the image into a saliency image (figure 2). For each region the presence or absence of a hazard is estimated, and a classifier is used to classify regions indicated as containing a possible hazard as either an obstacle to be avoided or non-threat regions. Two or more classifiers may be applied and a fused final classification for a region is determined by forming a weighted average. The hazard map may comprise combined saliency and feature data. The UAV may comprise a plurality of cameras with overlapping fields of view (figure 4). A combined hazard map may be generated covering the combined field of view of all the cameras.

Title: Replay attack protection
Inventor: FRANK AUNE
IPC: H04L9/40
Filed: 2021-05-24
Abstract: A method for preventing replay attacks at an electronic device. A device-specific identifier for the device and a local sequence value associated with an external party are stored 30 on the device. The device receives 32 a cryptographically signed message with an identifier field, a sequence-value field, and a cryptographic signature, and determines whether the received message is valid. To determine validity the device checks that: the cryptographic signature is associated with the external party 35, the cryptographic signature confirms the integrity of the identifier field and the sequence-value field, the received identifier field matches the stored identifier 33, and the received sequence-value field satisfies a sequence condition 34 determined in dependence on the stored local sequence value. Upon determining that the message is valid, the device updates 36 the stored local sequence value to correspond to the received sequence-value field. The device-specific identifier may be a public key which is stored with a private key as a key pair on the device and may be generated by the device. The sequence value may be configured so that it can only be erased, reset or decremented when the device-specific identifier is also erased or reset.

Title: Estimating noise levels
Inventor: MIIKKA TAPANI VILERMO
IPC: G10L21/0216
Filed: 2022-07-28
Abstract: A primary estimate of noise is made 403 and used to estimate direction and diffuseness parameters 405, which are used to predict a level difference 407 between two microphone signals 401. The level difference between those microphone signals is determined, and used together with the predicted level difference 413 to estimate the noise level 417. The process used to estimate direction and diffuseness parameters may depend on whether the primary noise estimate is above or below a threshold (fig. 5). The noise level may be estimated by adjusting a microphone signal level based on the determined level difference and comparing the adjusted signal to one or more other microphone signals. The diffuseness parameter may be a ratio of direct audio to ambient audio. The noise may be incoherent noise (such as wind noise). The method may be implemented in a device with two or more microphones 103, such as a handheld electronic device, a headset or face covering.

Title: Floating barrier system
Inventor: Erick Knezek
IPC: F41H11/05
Filed: 2022-03-02
Abstract: A floating barrier system has a plurality of connected floating barrier units. Capture net segments are positioned on the floating barrier units by support post members, forming a barrier to vessel passage. Lanyards attach the ends of the capture net segments to the floating barrier units. Upon a vessel striking the capture net segments with sufficient force, the capture nets detach from the support post members and/or pull the support post members over, and the forces from the vessel are transferred via the lanyards to the floating barrier unit. The vessel is prevented from fully passing over the floating barrier unit, thus itself forming a barrier to passage by other vessels.
