Handling or removal of a pair of defibrillator electrode pads from their package is detected in order to effectively time the issuance of prompts to guide the user. One plate of a capacitor is embedded in the package, the electrode pads and lead wires serving as the other plate. Impedance across the capacitor in an alternating current circuit is monitored to detect an increase in the distance between the pads and the package. The impedance level is determined, in a low-cost hardware solution, by rectifying and then integrating an output voltage of the capacitor to produce a voltage signal whose magnitude attenuates as the pads are handled or removed. In one embodiment, the above methodology is time-division multiplexed with an alternative process that identifies handling or removal based on pad-to-pad impedance. In a further embodiment, the capacitive configuration is replaced with an inductive one.

A system, method and apparatus for modulated control of a vehicle lighting systems is useful for brake lights and/or running lights in a motor vehicle. Various vehicle operating parameters are monitored to determine an appropriate modulation control mode for the vehicle. In some examples, the engine speed (e.g., in revolutions-per-minute or rpm) or vehicle speed (e.g., in miles-per-hour or mph, kilometer-per-hour or kmh, etc.) is used as a parameter for modulated control of the lighting system. The modulated control scheme is used to control any number of features of the lighting system including illumination color, illumination intensity, selection of sequence illumination pattern, and adjustment of sequence rate. The modulated control scheme may be applied to off-road buggy whip-lights or other aesthetic vehicle lights and safety enhancements. The modulated control scheme may be applicable for off-road and on-road vehicle applications where localized government ordinances permit.

A CATV system is provided that includes a head-end with laser transmitters to provide data to a multitude of nodes through a forward optical network tree. The nodes convert the optical signals into electrical signals and retransmit the television and data signals through a coaxial network tree to customer interface units (CIUs). The nodes include respective controllers which identify status signals from the equipment of the nodes and transmit the status signals and a reference signal to the head-end controller for display on a display of the head-end controller. The reference signal allows monitoring that the return optical transmitter and network are operating correctly and allows the return signals from the nodes to be aligned. The status signals from the nodes include laser operation, laser bias current and laser power output for the laser transmitters of the nodes.
