Abstract: The disclosure relates to a patch antenna that comprises at least two different arrays of conductive patches arranged on one side of a dielectric substrate. Each of the at least two arrays of conductive patches supports a different frequency band. Moreover, each of the at least two arrays of conductive patches is provided with separated feeding. Additionally, each conductive patch of one or more of the at least two arrays of conductive patches (e.g., those intended for low frequencies) is implemented as a combination two conductive sub-patches separated by a gap, which allows one to define an appropriate operating frequency bandwidth. This configuration of the patch antenna also allows one to individually design the size of each conductive patch, as well as an inter-patch spacing for each of the frequency bands. In one embodiment, the patch antenna is suitable for integration into a display structure of a UE.

Abstract: A communication interface for use at a first end of a communication link including a number of communication lanes greater or equal to two. The communication interface includes a logic configured to cooperate with another communication interface at a second end of the communication link to send a data frame to the second end over the communication lanes. The logic is configured to store a communication lane status for each of the communication lanes, and when detecting that the communication lane status for a specific communication lane has changed to a determined status. The logic is configured to send the changed communication lane status for the specific communication lane to the communication interface at the second end and split a data frame accordingly. The communication interface provides seamless data communication between the first end and the second end of the communication link, even in case of a lane failure.

Abstract: Systems and methods for emulating a floating-point unit are disclosed. The method receives one or more floating-point operands having a first floating-point format. Each of the one or more floating-point operands having the first floating-point format is converted into a first set of integers having the first floating-point format. Further, each of the first set of integers is converted into a second set of integers having a second floating-point format that is different from the first floating-point format. The first set of integers and the second set of integers each has a defined bit length depending on the respective floating-point format. Lastly, the method performs computations for a task using each of the second set of integers to emulate computations performed by the floating-point unit using the one or more floating-point operands having the second floating-point format.

Abstract: Disclosed is a routing device (1) for routing of one or more packets to a service function, for example a mining service associated with a digital ledger. The routing device (1) comprises a processor (11) configured to: establish (21) a number of constraints for the routing of the one or more packets to a number of instances (potential miners M) of the mining service function. The established number of constraints define prerequisites for a service provisioning (mining) by the number of instances (capable miners M). The processor (11) is further configured to: selectively forward (22) the one or more packets to all instances (potential miners M) of the mining service function in accordance with the established number of constraints. This avoids unnecessary acts of communication in connection with transaction mining for the digital ledger.

Abstract: Methods and devices are described for detecting code clones in a software program. The source code of the software program is processed into a group of n-gram representations. A clone index is generated for each respective code portion defined in the normalized source code, where each clone index includes a feature vector encoding features of the respective code portion based on the n-gram representations corresponding to the respective code portion. Comparison of the clone indexes is used to detect a code clone, based on matching the feature vectors of the clone indexes.

Abstract: Disclosed is a routing device (3) for routing of one or more packets to a service function. The routing device (3) comprises a processor (31). The processor (31) is configured to establish (11) a first forwarding state for an initial packet of the one or more packets to a number of instances (i) of the service function; receive (12) a service demand comprising the one or more packets; match (13) the received service demand and a second forwarding state for subsequent packets of the one or more packets to a particular one (i) of the number of instances of the service function; if the received service demand fails to match the second forwarding state, establish (14) the second forwarding state for the subsequent packets of the one or more packets, and send (15) a service request comprising the one or more packets to a next hop (NH) towards the particular one (i) of the number of instances of the service function in accordance with the first forwarding state; and if the received service demand matches the second forwarding state, send (15) the service request to a next hop (NH) towards the particular one (i) of the number of instances of the service function in accordance with the second forwarding state. This enables positively replying to a service demand despite the initially selected service instance being unable to.
