    Abstract: Apparatus and associated methods relate to a vibrational sensing system (VSS) including an accelerometer and a data processor, which determines an “operational state” of a mechanical drive unit, the processor further employing the “operational state” to gate learning of long-term vibrational data to exclude collection of non-operational data, the long-term data collected to calculate alarm thresholds. For example, vibrations from a target motor are sensed by a coupled accelerometer. Vibrational data from the accelerometer is fed into a data processor which determines the operational state of the motor. The operational state (e.g., on/off indication) may gate data collection such that data is only acquired during on-time, which may advantageously create accurate baselines from which alarm thresholds may be generated, and nuisance alarms may be avoided.

    Abstract: Apparatus and associated methods relate to a networked system having a master and multiple slaves, where each slave stores a unique (actual) slave address and a non-unique (virtual) slave address in memory, such that each slave is configured to respond to request messages addressed to the slave's non-unique slave address if a sensor device associated with the is in an active state when the slave receives the request message. In an illustrative example, the networked system may be a Fieldbus-style network (e.g., a network implementing the Modbus protocol). A sensor device may be a break-beam, capacitive touch, or push-button device, for example. An output indicator/actuator may be associated with a sensor device to indicate the status of the sensor device to a user. A networked system implementing sensor-activated response gating may beneficially expand the number of slave devices on the network while achieving low latency response times.

    Abstract: Indicator light devices are useful in many applications for indicating properties of physical spaces respectively associated therewith and in physical proximity thereto. The indicator light devices are network-enabled and self-powered, and capable of participating in coordinated power-managed operation to provide a sufficient service life and lower installation and replacement costs. The indicator light devices may be used with or without associated sensors. The various embodiments described herein use various power management techniques singly or in combination to greatly increase the service life of self-power indicator light devices without diminishing their effectiveness in the application. These techniques include operating only the indicator light devices associated with the physical spaces having properties of interest, operating the indicator light devices with synchronized flashing, operating the indicator light devices in accordance with the detection of specific conditions, relevant time operation, in-vicinity activation, and ambient light responsiveness.
