A method of monitoring a patient for phrenic nerve collateral damage during a cardiac ablation procedure. The method includes measuring at least one from the group consisting of compound motor action potential (CMAP) and accelerometer signals in response to stimulating of the phrenic nerve. Real-time data is displayed on a display, the real-time data including the at least one from the group consisting of the measured CMAP and accelerometer signals. Long-term trend data is simultaneously displayed on the display, the long-term trend data being associated with the measured at least one from the group consisting of CMAP and accelerometer signals.

A method and system of a predictive maintenance IoT system comprises receiving a plurality of sensor data over a communications network and determining one or more clusters from the sensor data based on a pre-determined rule set. Further, the sensor data is classified through a machine learning engine and the sensor data is further base-lined through a combination of database architecture, data training architecture, and a base-lining algorithm. Intensity or degree of fault state is mapped to a fuel gauge to be depicted on a user interface and a predictive maintenance state is predicted through a regression model and appropriate alarm is raised for user action.

A barcoded indicator operative to provide a machine-readable indication of exceedance of at least one threshold by at least one product quality affecting parameter, the barcoded indicator including at least a first barcode and at least a second barcode, the at least a second barcode being in a second barcode unreadable state prior to exceedance of the at least one threshold and upon exceedance of the at least one threshold the at least a first barcode becoming unreadable and generally simultaneously the at least a second barcode becoming readable.

This disclosure relates generally to motor vehicles, and more particularly to motor vehicle and device for visually indicating a speed of the motor vehicle, and method thereof. In one embodiment, a method is provided for visually indicating a speed of a motor vehicle. The method includes receiving an instantaneous speed of the motor vehicle from one or more odometry devices of the motor vehicle and an instantaneous temperature on an external surface of the motor vehicle from one or more temperature sensors. The method further includes configuring one or more thermoelectric couple strips to regulate temperatures of one or more corresponding thermochromic paint coating layers disposed on the external surface of the motor vehicle, based on the instantaneous speed and the instantaneous temperature, to dynamically control indication of a color pattern associated with a range of instantaneous speed of the motor vehicle.

A sensor unit for a fingerboard latch assembly comprising a latch bracket and a latch rotatably mounted on the latch bracket comprises a sensor arranged to sense the orientation of the latch and a wireless, optical or other communication unit arranged to communicate the orientation of the latch sensed by the sensor. The sensor unit may be mountable on the latch and comprise an orientation sensor arranged to take measurements that are dependent on the orientation of the sensor unit, and a processor arranged to derive an orientation signal representing the orientation of the latch from the measurements, the communication unit being arranged to communicate the orientation signal. A monitoring system receives the sensed orientations from plural sensor units.

A visually sensible indicator of temperature including electronic temperature sensing circuitry sensing at least when a temperature exceeds at least one predetermined temperature threshold and providing at least one corresponding threshold exceedance output which is sensible as heat and a heat-responsive visually sensible display which is responsive to the at least one threshold exceedance output for providing at least one visually sensible indication indicating that the temperature has exceeded the predetermined temperature threshold.

A display device for an internal combustion engine includes a variable compression ratio mechanism structured to vary an engine compression ratio of the internal combustion engine. The display device includes an indicator structured to vary its indication depending on the engine compression ratio. The indicator is configured to maintain the indication constant or within a slight change with respect to a change in the engine compression ratio within each of at least one of first and second dead zones of the engine compression ratio. The first dead zone includes a vicinity of an upper limit of the engine compression ratio including the upper limit. The second dead zone includes a vicinity of a lower limit of the engine compression ratio including the lower limit.

A method for signifying a selected cumulative scrubbing action between a device and a surface, the cumulative scrubbing action being signified by a signaling element, wherein the signaling element is configured to provide an observable signal when the selected cumulative scrubbing action has been provided to the surface. The method may comprise applying scrubbing action to the signaling element to release and/or expose at least a first portion of an indicator, and observing the device and/or surface for the signal. The present disclosure also relates to signaling elements and devices for use according to the methods of the present disclosure, and to methods of preparing the same.

This marking system is provided with: a marking device which has a marking unit which gives a mark for managing the quality of a product, a housing part which houses one or more temperature indicating materials, and a providing unit which provides, to the marking unit, a temperature indicating material selected by the housing part; and a control device which has a storage unit that stores temperature-indicating material information on a developing temperature or/and a decoloring temperature of each of the temperature-indicating materials included in the housing part; and a processing unit that acquires, from a server or an input unit, an appropriate temperature of the product, selects, on the basis of the acquired appropriate temperature of the product and the temperature-indicating material information, a temperature-indicating material, and notifies the providing unit of details of providing the selected temperature-indicating material.
