Abstract: A method for inspecting a component constructed of a conductive composite material. The method includes the step of passing an alternating current signal through the component through an electrical interface. The impedance of the component from either a reflected or a through passage of the electric signal is then determined. That impedance is then compared with empirical data to determine the type and extent of damage or deterioration of the component.

The tool includes a housing and a driver reciprocally mounted in the housing and moveable with respect to the housing, the driver having a driving surface for engaging a fastener such as a staple. A magazine assembly is associated with the housing for positioning and aligning the fastener in the path of the driver so that when actuated, the driver strikes the fastener and forcibly ejects it from the magazine into the substrate to a predetermined extent so as to adjust or control the holding power of the fastener about the object.

Abstract: One embodiment disclosed relates to an apparatus forming an electrical conduction path through an insulating layer on a surface of a substrate. A first radiation source is configured to emit radiation to a first region of the insulating layer, and a first electrical contact is configured to apply a first bias voltage to the first region. A second radiation source is configured to emit radiation to a second region of the insulating layer, and a second electrical contact is configured to apply a second bias voltage to the second region. The conductivities of the regions are increased by the radiation such that conductive paths are formed through the insulating layer at those regions. In one implementation, the apparatus may be used in an electron beam instrument. Another embodiment relates to a method of forming an electrical conduction path through an insulating layer. Other embodiments, aspects and features are also disclosed.

Abstract: A DC power supply control apparatus monitors respective terminals supplying positive and negative DC supply voltages to a utility device. The voltage at the negative terminal is compared with a target value for that voltage to produce an offset current representative of any voltage differential therebetween. This offset current is used to produce an offset voltage, that is added to or subtracted from a target value of the positive supply voltage to produce an error amplifier reference voltage. This reference voltage is compared with the voltage at the monitored positive terminal, to produce an error voltage, in response to which the power supply's modulator loop adjusts the power supply's positive output voltage, as necessary, to maintain the intended DC voltage differential between the positive and negative DC supply voltages.

Abstract: A current-sensing and correction circuit having programmable temperature compensation circuitry that is incorporated into a pulse width modulation controller of a buck mode DC—DC converter. The front end of the controller contains a sense amplifier, having an input coupled via a current feedback resistor to a common output node of the converter. The impedance of a MOSFET, the current through which is sampled by a sample and hold circuit is controlled by the sense amplifier unit. A sensed current correction circuit is coupled between the sample and hold circuit and the controller, and is operative to supply to the controller a correction current having a deterministic temperature-compensating relationship to the sensed current. The ratio of correction current to sensed current equals to value of one at a predetermined temperature, and has other values at temperatures other than at that temperature.
