Patent number: 9134100Abstract: A semiconductor bridge die may have an “H-design” or “trapezoidal” configuration in which a center bridge segment is flanked by one or more angled walls on each side of the bridge segment. Each wall is plated with a conductive material, thereby providing a continuous conductive path across the top surface of the die. A bottom surface of the die may be connected to a top surface of a header by epoxy in various configurations. The plated angled walls facilitate the solderable connection of the walls to a plated top surface of each of several pins on a top surface of the header, thereby providing a continuous electrical connection between the pins and the die. Also, a method is provided for manufacturing a semiconductor bridge die in accordance with the various embodiments of the die.Type: GrantFiled: April 6, 2010Date of Patent: September 15, 2015Assignee: ENSIGN-BICKFORD AEROSPACE & DEFENSE COMPANYInventors: Bernardo Martinez-Tovar, Craig J. Boucher

Patent number: 7278658Abstract: An ordnance system of the present invention may include or feature any one or more of: a control unit, one or more effectors (detonators, initiators, shaped charges and the like), and a two-, three- or four-wire communication bus between the control unit and the effectors; an addressable system in which all the effectors can be connected to the same communication bus and the control unit can issue coded signals on the bus addressed to a specific effector; inductive coupling between the effectors and the communication bus; and a multi-voltage level communication system in which communication signals are carried at a first voltage and arming signals are provided at a second, higher voltage. Other features may include two-way communication between effectors and the control unit and the de-centralization of firing control so that the control unit does not have exclusive control over whether the effectors function.Type: GrantFiled: April 5, 2005Date of Patent: October 9, 2007Assignee: Ensign-Bickford Aerospace and Defense Co.Inventors: Craig J. Boucher, Paul N. Marshall, David B. Novotney

Patent number: 5477785Abstract: A well pipe perforating gun (10) is improved by the utilization of a pulverable support structure (14) to hold the explosive shaped charges (18a, 18b, etc.) and the fireset (20). When the gun (10) is fired, the support structure (14) disintegrates substantially into fragments too small to obstruct the flow of oil or natural gas from a surrounding earth formation into or through the well pipe (12) within which the gun is disposed. Optionally, the support structure (14) is assembled from a number of segments (14a, 14b, etc.) linked together in sequential fashion.Type: GrantFiled: January 27, 1995Date of Patent: December 26, 1995Assignee: The Ensign-Bickford CompanyInventors: Charles A.

Patent number: 5476044Abstract: An electronic safe/arm device is powered internally by a low-voltage, periodic power source that has insufficient voltage by itself to fire the detonator. The circuit therefore includes a step-up transformer from which sufficient voltage to fire the detonator is obtained. The step-up transformer charges an arming circuit which stores high-voltage power to fire the detonator and also powers the firing circuit which discharges the stored high-voltage energy through the detonator at the appropriate time, to fire the device. The low-voltage, periodic power source may include a low-voltage battery and a dynamic switch for providing periodic pulses of low-voltage energy to the primary winding of the transformer, and the dynamic switch may be powered from the output of the transformer, so that the low-voltage battery has insufficient voltage to power the dynamic switch.Type: GrantFiled: October 14, 1994Date of Patent: December 19, 1995Assignee: The Ensign-Bickford CompanyInventor: Craig J.
