Abstract: A computer-implemented method for maintaining a function of a local entity upon connection disruption to a backend in a communication system including a backend and a plurality of local entities. The backend provides backend information for the function. The method includes reception of local behavior models from a plurality of local entities by the backend, wherein the local behavior models provide the function in the local entities if particular backend information is not available; creation of a behavior model based on the received local behavior models; and transmission of the behavior model to a local entity of the plurality of the local entities by the backend.

Abstract: A computer-implemented method for preventing loss of function in a local instance when there is a disturbance of a connection to a backend in a communication system that has a local instance having a local agent and a backend acting in part as a global agent, an agent designating a unit that is designed to achieve defined goals through autonomous behavior. The method includes, when there is a connection to the backend, the providing of the function by the global agent, which receives backend information from the backend during the providing of the function, and, if a connection to the backend is disturbed, the providing of the function by the local agent.

Abstract: A method and device for handling an anomaly at a unit. The device is integrated into the unit. A variable is detected for handling attacks on the unit that defines an operation of the unit. A piece of information is determined depending on the variable that characterizes surroundings in which the unit is operated. It is checked depending on a comparison of the piece of information about the surroundings to a piece information about the setpoint surroundings for the operation of the unit, whether or not an anomaly is present in the operation of the unit. The unit is operated in a first operating mode having a first functional range, if no anomaly is detected. The unit is operated in a second operating mode having a second functional range, which is reduced or changed with regard to the first functional range, if an anomaly is detected.

Abstract: A method for communicating data requests to one or more data sources. The method includes receiving a data request, with which data of one or more data types are requested, from an application, and checking the availability of one or more data sources that are able to provide the one or more requested data types. The method further comprises: if at least one of the one or more data sources is available, sending a request to the available data source for the requested associated data type that the data source can provide; and, if no data source is available for at least one of the requested data types, sending a request for this data type to a placeholder module.

Abstract: The present invention relates to electric appliances for personal care, in particular electric shavers, comprising a magnetic linear drive unit having first and second drive components supported for linear displacement relative to each other and adapted to magnetically interact with each other, wherein a drive support is provided for supporting the drive unit onto a mounting structure. The drive support supporting the drive unit onto a mounting structure of the installation environment is adapted to provide for at least one axis of rotation for at least one of the drive components of the drive unit allowing said at least one drive component to rotate relative to the mounting structure.

Abstract: An active noise reduction earphone includes a speaker, a plurality of microphones and a feedback system. Each microphone is displaced from the speaker and the other microphones, and each microphone generates a microphone signal responsive to received acoustic noise. The feedback system receives a combination of the microphone signals and generates an inverse noise signal that is applied to the speaker. The speaker generates an inverse acoustic noise signal that substantially cancels the acoustic noise signal at a predetermined location relative to the speaker and the microphones. The feedback system can include a microphone signal combiner in communication with the microphones. The microphone signal combiner generates a signal that may be a sum or weighted sum of the microphone signals and can be used to generate the inverse noise signal. The earphone has an increased noise reduction bandwidth and improved cancellation capability relative to conventional earphones.

Abstract: The invention relates to a small electrical appliance for removing hairs, with a handpiece extending in the direction of a center axis and provided with front and rear sides and side faces, and with an operating head which is secured on the handpiece via a retaining device and has an operating unit. The operating unit is composed of at least one operating element which is set in motion via a drive member by an electrical drive motor formed in the small appliance, such that, when the operating unit slides along the skin surface of a user, hairs are removed by the operating unit. The retaining device is connected to the handpiece via guide means in such a way that, when a force (F1 or F2) acts on the operating head in the guiding direction, at least a lateral movement (c or d) of the operating head relative to the handpiece takes place.
