Abstract: An MFA smart contract wallet provides security for blockchain transactions by enforcing MFA rules, for example a rule requiring that a user confirm a blockchain transaction by submitting separate requests containing the transaction's recipient, call data, and value to the MFA smart contract wallet from multiple different externally owned accounts, with each request being signed by a separate corresponding private key.

Abstract: NFTs are used to provide software licensing and DRM in a manner that is transferrable, allowing licensees to swap and resell licensed software according to terms specified by the licensor. NFTs are used to prove ownership of software and other digital assets on a blockchain. The blockchain provides a distributed public ledger that enables the tracking of ownership of the assets, without the use of a centralized server. Since software and other digital content licenses concern digital assets, they can be granted, tracked, and revoked on the blockchain via the use of NFTs. NFTs and the blockchain therefore provide a mechanism which is used to verify and authenticate software licenses, digital content licenses, and other types of licenses for digital assets. Smart contracts may be used to define and enforce the terms of the licenses, at any level of granularity.

Abstract: An energy-saving method for wireless reception of data modulated on a carrier signal is carried out in a receiver circuit including a first group and a second group of circuit elements. The first group of the circuit elements required for recovering the data from the modulated carrier signal are supplied intermittently with electrical energy, while the remaining circuit elements of the second group are supplied with uninterrupted electrical energy. After an intermittent unpowered phase without electrical energy being supplied to the first group of circuit elements, the receiver can be operated in the next intermittent powered phase of the second group of circuit elements with parameters that determined the receiver properties which were present in the last reception phase and that have been stored, thus eliminating the time required for renewed tuning in.

Abstract: The present invention relates to an energy-saving method for the wireless reception of data modulated on a carrier signal by means of a receiver circuit including a first group and a second group of circuit elements.

Abstract: The invention relates to an opto-electronic component having a narrow aperture angle. The conventional design of components transmitting radiation or reacting to radiation and concentrating that radiation with the aid of lenses results, on account of the increasing distance between the lens and the semiconductor chip, in increasing component dimensions in the radiating or detecting direction with an increasingly narrow aperture angle. In accordance with the invention, a parabolic or approximately parabolic reflector is provided that is connected to a support strip supporting the semiconductor chip such that the latter is as close as possible to the focal point of the parabolic or approximately parabolic surface of the reflector. The reflector is preferably connected to the support strip by engaging elements and surrounded by a housing.

Abstract: A semiconductor assembly with a metal frame configuration is described, having a semiconductor component (HL) on a carrier section (T) of a ground strip section (M). The ground strip segment has an extension section (V) with which it is extended beyond said carrier section and is both folded over in relation to said carrier section and of sufficient length that it covers said semiconductor component in order to shield it electromagnetically.In this assembly, the ground strip section has a multiple function. It is used not only for carrying and contacting of electrical components, but also acts at the same time as electromagnetic shielding for a semiconductor component, for example for the radiation detector of a remote control reception module.
