The antenna includes at least one antenna trace; a first antenna terminal; and a second antenna terminal. The decoupler component includes a first decoupler component terminal and a second decoupler component terminal. The integrated circuit is electrically coupled to the first antenna terminal and the second antenna terminal. The integrated circuit is electrically coupled to the first decoupler component terminal. The second decoupler component terminal is electrically connected to the ground plane.

Indicator circuit decoupled from a ground plane

Communications systems including multiple computer devices where: (i) for a set of computer devices, used by a common user, it is determined which computer device the user is most actively using; and (ii) an operational mode of a “wireless service” (see definition, below) on one of the other computer devices (that is, a non-most-active computer device) is changed in its operational mode. For example, if a user has two smart phones and the user's first smart phone is determined to be more active than the second smart phone, then on the second smart phone (that is, the non-most-active computer device) a social media home page updating service is turned off. In some embodiments, the change from first operational mode to second operational mode will mean that wireless transceiver hardware (such as an antenna) is turned off for the non-most-active device(s).

Disclosed are systems for wireless energy transfer including transcutaneous energy transfer. Embodiments are disclosed for user interface (UI) hubs to connect multiple batteries and to output system information to a patient. Embodiments are further disclosed for garments and devices to be worn by a patient requiring treatment. The garments are configured for a desired placement of a transmitter coil relative to a body of the patient and for facilitating patient comfort and quality of life. Methods for manufacturing and using the devices and the systems are also disclosed.

Wireless energy transfer system and wearables

A positive terminal of a battery may act as an antenna ground plane for communicating battery status information. The positive terminal of the battery may include a first electrically conductive external surface with a first surface area. The negative terminal of the battery may include a second electrically conductive external surface with a second surface area less than the first surface area. An antenna impedance matching circuit may be electrically connected between a communication circuit, an antenna, and the positive terminal of the battery. Thus the positive terminal of the battery may act as a ground plane for the antenna.

Positive battery terminal antenna ground plane

A device for operation as part of a system or network, the device combining a power cell, a battery housing enclosing the power cell, and an on-board radiobeacon within the housing, where the battery is configured to supply DC power to an external apparatus and to the radiobeacon in parallel. A sensor or sensor package may also be included in the battery device and reports to the system or network. In response to a sensor or clock-derived trigger, a microcontroller in the battery uses the radiobeacon to broadcast messages to a radio receiver of a smart device or a network system. The radiobeacon has a unique identifier, and because the messages are low energy, low power radio transmissions having a maximum range of less that about 300 ft (about 100 m). Any smart device or network receiving the beacon signal may track, map and monitor the signal from the device.
