A master entity is capable of broadcasting commands to slaves which move to another state when they satisfy a primitive condition specified in the command. By moving slaves among three sets, a desired subset of slaves can be isolated in one of the sets. This desired subset of slaves ten can be moved to one of the states that is unaffected by commands that cause the selection of other desirable subsets of slaves. In the incorporated U.S. Pat. Nos. 5,550,547 and 5,673,037, certain subgroups of radio frequency tags are selected for querying, communicating, and/or identifying by commands from a base station.

System and method for radio frequency tag group select

A system and method for delivering electronic messages over a wireless cellular communications network when the sender of a message is out of the coverage area of any cell within the network. With this method the message is broadcast repeatedly until a mobile wireless courier receives the message when it is range and stores the message. When the courier is within range of a base station of the cellular communication network, it then transmits the stored message to the base station for transmission to a requested destination.

The packet network phone unit is an interface between a telephone instrument and a packet network for enabling voice data to be communicated over the packet network. The unit also functions as a gateway between a packet network and a public switched telephone network, thereby interconnecting the networks and providing a public switched telephone network gateway to a packet network. When power is not supplied to the unit, a fallback switch automatically links the telephone instrument directly to the public switched network, bypassing the circuitry in the unit. The unit includes links to a plurality of external serial communications lines as well as an interface for connecting to a personal computer. The unit also includes an LCD driver and a display for displaying information such as a caller identification. The packet network phone unit also may function an answering machine/messaging system.
