Abstract: This invention describes apparatuses/methods for data compression/decompression, wherein input observation data is classified into types of semantic objects according to one or more criteria and a compression technique is applied to the object types based on their ease of reconstruction via a compression model to obtain compressed data. The classification may be performed based on the performance of the compression model. A suitable descriptive prompt may be generated, e.g., based on a textual inversion technique, for a data object belonging to a data object type that can be well reconstructed. Furthermore, the invention may be applied for personalized data compression/construction/decompression/reconstruction, wherein an encoder/decoder takes a suitable personalized descriptive prompt (or program) and/or a personalized reconstruction model and/or a personalized policy to generate personalized content according to the user's preferences and/or profile.

Abstract: The invention relates to a sensing and communication system for sensing targets (objects or people) in an environment, 2024/094745 wherein first real sensing data of a target collected by a first device is used to generate synthetic data which emulates second real sensing data which would be produced by a second device of the same target. The synthetic data is then used to determine whether the second real sensing data collected by the second device matches the first real sensing data collected by the first device, such that it can be confirmed whether both devices are sensing or have sensed the same target, or to identify objects in the field of view of a device (e.g., AR glasses).

Abstract: Systems and methods for providing sensing capability in a wireless communication system, wherein a part of the communication spectrum is configured for a period of time to enable performing sensing by establishing a distributed sensing system between a base station (100) or terminal device, as transmitter device, and a terminal device (120) or base station, as receiver device, in such a way that the lack of analogue signal exchange and the additional path length caused by the transmitter-receiver distance (and, in embodiments, the receiver-target distance) are corrected for, while parameters that need to be communicated are configured for the application required.

Abstract: The invention proposes systems and methods for testing on-device machine learning models such as network models of a device based on an access to normal input and output channels, wherein a structure of a model is designed through training such that the model produces distinctive outputs to a given set of test inputs only so long as its internal structure remains in a desired state. Models may be rendered susceptible to such testing via model pre-training with training inputs designed to train the model into an appropriate structure and/or to cause the model to produce a distinctive output if later presented with a certain set of test inputs. If the structure of the model remains within allowable limits, the device will produce a predictable output when tested. If not, the device may be enforced to return to a pre-trained model.

Abstract: A head mounted information processing device, an authentication system, and an authentication method capable of achieving an improvement in security are provided. Thus, a head mounted information processing device 1 includes a display 45 configured to display an image, a microphone 50 configured to collect a voice of a user and output an audio data signal, a biometric authentication sensor 30 configured to acquire tomographic data of a head of the user, and a controller (20) configured to control the head mounted information processing device 1. The controller (20) authenticates the user based on the tomographic data acquired by the biometric authentication sensor 30 during an authentication period in which the user is uttering a passcode.

Abstract: A solar concentrator comprises a curved linear Fresnel lens (16) which has a plurality of prismatic features (10, 12, 14). The prismatic features are arranged into at least two segments, in each segment the prismatic features have a common apex angle, the common apex angle differing between adjacent segments. A method of manufacturing a mold (2) for producing a Fresnel lens optical film (16) is disclosed. The method comprises rotating a mold blank, and forming a plurality of different prismatic features (10, 12, 14) on the mold blank by repeatedly advancing a cutting tool (4) onto and then withdrawing the tool away from the surface of the mold blank.

Abstract: A point focus thin film Fresnel lens (15; 25) has an inner, substantially flat region (8; 22), and an outer region (9; 23), the outer region projecting outwardly from the inner region and at a substantial angle away from the plane of the inner region. In one embodiment the lens is in the form of a truncated cone (15) with a circular inner region as its apex, hi another embodiment the lens is in the form of a dome (25) and the outer region is formed by joining together segments (23) extending radially from a circular central region (22).

Abstract: The present invention provides a nanostructure comprising a plurality of nanoridges wherein the height of each nanoridge is modulated whereby to form one or more peaks (e.g. a series of peaks) along the length of each nanoridge.
