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.

Patent number: 6311621Abstract: A shock-resistant electronic circuit assembly (10) is provided in which an electronic circuit is encased in an encapsulation (14) that engages a surrounding enclosure (18) in shock-dispersing contact therewith. The encapsulation may have a plurality of edges (16, 16a, 16b), fins (24) or bosses (70) that bear against the enclosure. The encapsulation may include a shock-absorbing material (14f) disposed against the enclosure to protect the circuit against vibrations and a structural support material such as a casing (14e) to protect the circuit against stress. The circuit assembly (10) may be part of a sheathed initiator assembly (55) that includes a transfer member (58) for converting shock wave energy into electrical energy for the electronic circuit, and the released energy may be converted into a detonation initiation signal. Assembly (55) may be part of a detonator (100) that receives a non-electric initiation signal and detonates following the delay determined by the electronic circuit.Type: GrantFiled: December 6, 1999Date of Patent: November 6, 2001Assignee: The Ensign-Bickford CompanyInventors: Paul N. Marshall, Thomas C. Tseka, Brendan M. Walsh, James E. Fritz

Patent number: 5929368Abstract: An electronic delay circuit (10) for use in a detonator (100) has a switching circuit (20) and a timer circuit (22). Switching circuit (20) controls the flow of a stored charge of electrical energy from a storage capacitor (12) to a bridge initiation element such as a semiconductor bridge (18) or a tungsten bridge. The timing of the release of this energy is controlled by timer circuit (22). Switching circuit (20) is an integrated, dielectrically isolated, bipolar CMOS (DI BiCMOS) circuit, whereas timer circuit (22) is a conventional CMOS circuit. The use of a DI BiCMOS switching circuit allows for greater efficiency of energy transfer from the storage capacitor (12) to the semiconductor bridge (18) than has previously been attained.Type: GrantFiled: December 9, 1996Date of Patent: July 27, 1999Assignee: The Ensign-Bickford CompanyInventors: David W.

Patent number: 5510267Abstract: A lytic agent is described which when mixed with whole blood, lyses the red cells instantly, but does not affect the optical, light scattering properties of the white blood cells for at least 30 seconds. This lytic agent enables the performance of a five part leukocyte differential by flow cytometry and light scattering. In its preferred embodiment, the lytic agent incorporates 2-phenoxyethanol which combines the functions of leukoprotective and antimicrobial, TRITON X-100 (octylphenoxypolyethoxyethanol) a lytic and wetting agent and TRIS/HCl to provide pH buffering and to increase the solution's conductivity.Type: GrantFiled: August 24, 1992Date of Patent: April 23, 1996Assignee: Abbott LaboratoriesInventor: Paul N.

Patent number: 4743836Abstract: A capacitance pressure measuring circuit includes a pressure sensitive capacitive transducer and a reference capacitor that are configured in a differential mode to alternately charge and discharge in response to square wave signals. An integrator receives signals from the capacitors and outputs two voltage levels. These voltage levels are provided to a synchronous clock driven selectable sample and hold stage and then to a differential amplifier. The amplifier provides a linear voltage signal proportional to the change in the difference in capacitance of the transducer divided by the capacitance of the integrator.Type: GrantFiled: December 6, 1985Date of Patent: May 10, 1988Assignee: United Technologies CorporationInventors: Richard R.
