Abstract: The present invention is directed to devices and methods that provide a user of a decentralized asynchronous parallel-configured wireless communication system for voice, data and live digital video streaming communication with the ability to select various communication paths and calling bandwidths as needed. The system uses a novel Time-Shared Full Duplex (TSFD) protocol for communications. The TSFD protocol allows the transmission of live digital video signals from one wireless device to another wireless device. The system provides local communication as well as optional links to external networks, and does not require a synchronous centralized switching center. It further provides secure operation, emergency notification and a way to collect revenue from the system, and allows for control of the operational state of the internal network and optional remote control of the operational state control of systems external to the network.

Abstract: The present invention is directed to a Time-Shared Full Duplex (TSFD) asynchronous wireless communications protocol for use in a TSFD wireless communication system. The wireless protocol utilizes broadband PCS radio frequency (RF) spectrum with PCS low band reserved for receive frequencies and PCS high band for transmit frequencies. The radio frequencies can be received or transmitted by a TSFD wireless device or a signal extender or a network extender.

Abstract: A buckle (10) including a plug (30) and a socket (20) is provided with a posture-adjuster that adjusts relative postures of the plug (30) and the socket (20) in a direction that leads a longitudinal axis (A2) of the plug (30) and a longitudinal axis (A1) of the socket (20) to be parallel when the plug (30) is relatively moved in a direction toward inside of the socket (20) from an insertion slot (21) thereof. The posture-adjuster has a guide path (24) that is provided to the socket (20) and has a width that becomes wider as being closer to the front end side thereof as well as a step portion (36) as a guided member that is provided to the plug (30) and guided by the guide path (24).
