    Abstract: A system and method for conducting a firing sequence including a master device and a plurality of electronic pyrotechnic devices, wherein the master device broadcasts, multiple times, a fire command to the plurality of electronic pyrotechnic devices, the electronic pyrotechnic devices commence a pre-fire countdown in response to each fire command received without error, and each electronic pyrotechnic device conducts a pre-fire countdown to expiration and thereupon commences a final fire countdown that concludes with firing.

    Abstract: A low-voltage-insensitive electro-pyrotechnic device comprising electrical input terminals, a bridge element connected to the electrical input terminals, and a transient voltage suppressor connected between the bridge element and one of the electrical input terminals. The device may utilize one bidirectional TVS on one side of the bridge element or two unidirectional TVSs on opposite sides of the bridge element, and may also include one or more resistors and/or an RF filter between the input terminals and bridge element.

    Abstract: For use in a system having a master device and slave devices (e.g., an electronic blasting system) and utilizing an automatic detection process that causes any slave devices that have not previously been identified to the master device to identify themselves to the master device, an enhancement to the detection process employs at least a second discriminator to detect superimposed responses from simultaneously responding slave devices, and a “deconvolution” algorithm in order to ascertain their identities.

    Abstract: A method of dynamically- and continuously-variable rate asynchronous data transfer, such as for use in an electronic blasting system, may employ a device that transmits data including synchronization bits and bits conveying other information, and a device that ascertains the rate of transmission of the synchronization bits and receives the bits conveying the other information at the ascertained rate of transmission.
