| 20090260532 | Method for Assigning a Delay Time to Electronic Delay Detonators - In the method for assigning a delay time to an electronic delay detonator. The detonator includes a data register ( | 10-22-2009 |
| 20090301333 | ELECTRONIC BLASTING SYSTEM HAVING A PRE-FIRE COUNTDOWN WITH MULTIPLE FIRE COMMANDS - 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. | 12-10-2009 |
| 20100275799 | METHOD OF COMMUNICATION AT A BLAST SITE, AND CORRESPONDING BLASTING APPARATUS - Blasting operations for mining frequently involve a large number of detonators for a single blasting event. An important step in the execution of a blast is to perform a roll-call to check that all detonator assemblies placed at the blast site are in communication with a blasting machine, and forming operative components of the blasting apparatus. Disclosed herein are blasting apparatuses and methods of blasting that streamline this roll-call step, thereby reducing time consumed in the blasting process. | 11-04-2010 |
| 20100288149 | DENTONATOR CROSS-TALK REDUCTION - A detonator system ( | 11-18-2010 |
| 20110056400 | Detonation Control System - According to certain embodiments, a detonation control system includes a controller circuit coupled to a manual switch and a detonation device. The detonation device is configured to activate an explosive. The controller circuit includes a memory operable to store one of a multiple time-to-fire settings representing a time delay from arming the detonation device to activation of the detonation device. The controller circuit is operable to store a first time-to-fire setting in the memory, store another of the multiple time-to-fire settings in the memory upon actuation of the manual switch, and repeat the step of storing another of the multiple time-to-fire settings in the memory for each actuation of the manual switch. | 03-10-2011 |
