Abstract: Electronic time delay apparatuses and methods of use are disclosed. An explosive or propellant system, which may be configured as a well perforating system includes an electronic time delay assembly comprising an input subassembly, an electronic time delay circuit, and an output subassembly. The input subassembly is activated by an external stimulus, wherein an element is displaced to activate an electronic time delay circuit. The electronic time delay circuit comprises a time delay device coupled with a voltage firing circuit. The electronic time delay circuit counts a time delay, and, upon completion, raises a voltage until a threshold firing voltage is exceeded. Upon exceeding the threshold firing voltage, a voltage trigger switch will break down to transfer energy to an electric initiator to initiate an explosive booster within the output subassembly. The explosive booster provides a detonation output to initiate the next element explosive or propellant element, such as an array of shaped charges in the well perforating system.

Abstract: A bandgap reference circuit and method of using the same are provided. The bandgap reference circuit may provide start-up requirements at substantially any voltage and at substantially any temperature. The circuit comprises an op amp (two stages of transistors) and a network of resistors and bipolar diodes. When an artificial offset of about −5 mV is introduced to the op amp, the op amp output will be high as soon as the power supply exceeds the transistors' threshold voltages. The op amp output supplies the resistor and diode network and brings the op amp inputs within desired regulation voltages.

Abstract: An electrolytic filter system (16) is disclosed for use in treating fluid provided by a fluid source(12) to a supplied environment (14). The system includes an electrolytic cell(18) controlled by control circuit(20). Various alternative constructions of the cell are described in which the effective separation of active electrodes, as well as the effective area of the active electrodes can be altered by a switching circuit (94) and controller (96) included in the control circuit (20). The controller responds to inputs from a current sensor (92) reflecting variations in the resistivity of the water. As a result, the controller is able to alter the effective separation and area of the active electrode, in response to resistivity variations to provide optimal operation.
