Abstract: There is provided a charger for charging a wearable device, comprising a charger head comprising a first connector with positive polarity; and a second connector with negative polarity, wherein the first connector and the second connector are arc-shaped.

Abstract: There is provided a wearable device, comprising connectors comprising a first connector and a second connector for interfacing with another device and/or a charger; a first switch for connecting the first connector and the second connector to a battery charging circuit of the wearable device; a second switch for connecting the first connector and the second connector to a communication circuit of the wearable device; a control unit configured to: enable an electrical connection between the connectors and the battery charging circuit, when the first switch is closed and the second switch is open; and enable communication with another device for data transfer via the connectors, when the first switch is open and the second switch is closed.

Abstract: A method and a system for filtering a data stream in a telecom-munications network. The objective of the invention is to provide a filtering mechanism for a data stream whereby the amount of data in the stream is reduced without using compression and with a minimal loss of channel in-formation content. The system comprises two logically different memories. The first memory (201) is used to store channel control information and the second memory (202) to store channel information according to the control channel information stored in the first memory. The fill rate of the first memory is monitored and the content of the second memory is checked by the control unit (200).

Abstract: The invention relates to a redundant switching arrangement using a first and second switching network (SWF_A, SWF_B) or other switching element. The switching elements are used to carry out switching operations in the same way, so that one of the switching elements serves as an active switching element whose switching operations are utilised, while the other switching element serves as a passive switching element backing up the active switching element. To ensure that any faults occurring in the switching elements in such a redundant switching arrangement are detected as quickly as possible, their operation is monitored by comparing the data of the corresponding output channels of the first and second switching elements, and if such a comparison shows that the data contained in any of the corresponding output channels are not identical, an internal test is carried out for at least one of the switching elements to verify the data of the output channel involved.
