Abstract: An active noise reducing earphone includes a rigid cup-like shell having an inner surface and an outer surface is provided. The inner surface encompasses a cavity with an opening, and a microphone arrangement is configured to pick up sound with at least one steerable beam-like directivity characteristic, and to provide a first electrical signal that represents the picked-up sound. The earphone further includes an active noise control filter configured to provide, based on the first electrical signal, a second electrical signal, and a speaker disposed in the opening of the cavity and configured to generate sound from the second electrical signal. The active noise control filter has a transfer characteristic that is configured so that noise that travels through the shell from beyond the outer surface to beyond the inner surface is reduced by the sound generated by the speaker.

Abstract: In one embodiment, a match application identifies an edge corresponding to a road segment based on an observational point specifying an estimated position and an estimated heading. The match application performs search operations on a road network graph based on the estimated position to identify multiple candidate edges. For a first candidate edge, the match application computes a first quality level based on at least a distance between the estimated position and the first candidate edge and an angle between the estimated heading and a direction associated with the first candidate edge. Subsequently, the match application determines that the first quality level indicates that the first candidate edge has a higher quality than any other candidate edge. Finally, the match application transmits the first candidate edge to an application that associates content specified in relation to the estimated position with the first candidate edge.

Abstract: In order to be able to detect a possible loss of cut during the thermal separation of a workpiece as early as during the separation, the invention proposes a method for detecting an impending loss of cut or a loss of cut that has already occurred, in which energy is input into a cutting region and which comprises the following method steps: a) applying a first alternating signal to the workpiece, b) identifying a second alternating signal caused by the first alternating signal in a measurement electrode spaced apart from the workpiece, c) ascertaining the phase shift between the first and second alternating signal by outputting a phase shift signal, d) comparing the phase shift signal with a prescribed upper limit value and a prescribed lower limit value for the phase shift signal, wherein, when the phase shift signal exceeds the upper limit value or undershoots the lower limit value, the energy input is changed, for example, by stopping the thermal separation of the workpiece.

Abstract: Efficiently and reliably tracking information for devices in a network, for example, a heterogeneous network of a plurality of devices of different types, includes collecting and storing information in a computationally efficient and secure manner that ensures to a high degree of certainty the integrity of the information for future access and use. The information may be collected from one or more sensors/data sources, for example, over a predetermined period of time, and may be grouped into a single transaction record. The transaction record may be sent from a gateway to a server of a network cloud, for example, during a predefined time slot of cycle based in part on the number of gateways and sensors in the system. Each transaction record may include a one-way hash of, and a reference to, an immediately preceding transaction record for the overall system for which information is being tracked.
