A multi-channel and multi-zone audio environment is provided. Various inventions are disclosed that allow playback devices on one or more networks to provide an effective multi-channel and a multi-zone audio environment using timing information. According to one example, timing information is used to coordinate playback devices connected over a low-latency network to provide audio along with a video display. In another example, timing information is used to coordinate playback devices connected over a mesh network to provide audio in one or more zones or zone groups.

A radiofrequency transmission/reception device includes a first and a second conductive wire element, a first far-field transmission/reception chip and a second near-field transmission/reception chip. The first and the second wire element combine with the characteristic impedance of the second transmission/reception chip in order to form a coupling device associated with the first transmission/reception chip at the operating frequency of the first chip. The first and the second wire element combine with the characteristic impedance of the first transmission/reception chip in order to form a coupling device associated with the second transmission/reception chip at the operating frequency of the second chip.

A radio terminal (3) can perform carrier aggregation using a first cell (10) of a first radio station (1) and a second cell (20) of a second radio station (2). The first radio station (1) performs, with the radio terminal (3), radio resource control for the first cell (10) and the second cell (20) in order to perform the carrier aggregation. At least one of the second radio station (2) and the radio terminal (3) is configured to transmit, to the first radio station (10), information about a problem occurring in a radio link in the second cell (20) between the second radio station (20) and the radio terminal (30) while the carrier aggregation of the first cell (10) and the second cell (20) is being performed.

Systems and methods for managing communication strategies between implanted medical devices. Methods include temporal optimization relative to one or more identified conditions in the body. A selected characteristic, such as a signal representative or linked to a biological function, is assessed to determine its likely impact on communication capabilities, and one or more communication strategies may be developed to optimize intra-body communication.

Electrically powered accessories connected to vehicle power systems are authenticated, and connections between the accessories and the vehicle power systems are based on permissions resulting from that authentication. accessories may supply authentication information associated with an authentication level, and form a permitted connection based on the authentication level. Vehicle power systems may obtain the authentication information, obtain the authentication level, and operate a power connection according to the authentication level. Authentication information can be obtained from the component or from a user of the component through, for example, a portable device. A system may include the electrically powered component and the vehicle power system. The system may further include a remote server to process the authentication information and determine the authentication level.
