A distribution list identifies a plurality of recipient addresses for electronic messages. Normal updates to the distribution list can be performed via update commands from an authorized address that is stored in association with the distribution list as authorized to update the distribution list. When a removal command is received from a specific recipient address, which is not authorized to update the distribution list, the specific address can be removed from the distribution list. When an addition command is received from the specific address, a new address can be added to the distribution list. Before sending an outbound electronic message, the distribution list is resolved to the current set of recipient addresses.

Electronic message distribution lists

A mobile wireless communications device includes a near-field communications (NFC) transceiver, NFC antennas and an NFC control circuit. The NFC transceiver generates a received signal strength based on a received signal from an adjacent NFC device. The NFC control circuit includes an antenna switch circuit coupled between the NFC transceiver and the NFC antennas. A capacitance sensing circuit is coupled to the NFC antennas to determine capacitance values thereof. A processor operates the antenna switch circuit based upon the received signal strength and the capacitance values.

A method for providing location information such as a map in an underground or shielded environment entails storing first near-field communication (NFC) data obtained by reading a first NFC tag at a first location, reading a second NFC tag at a second location, obtaining map data for an area encompassing the first and second locations, and displaying a map showing the first location and the second location.

Mobile mapping in underground or shielded environments

An adaptive printed circuit board (PCB) connector consists of an adapter. The adapter comprises a printed circuit board having connectors connectable to battery terminals of a battery terminal structure of a populated circuit board (POP) of a mobile device. The adapter can have an opening shaped or adapted to receive the battery terminal structure of the POP. Battery terminals can be spring loaded. Spring loaded battery terminals can provide connective stability between POP and adapter by pushing against edge inside of opening of the adapter.
