Sensor

Embodiments of a sensor device, method and system employ one or more particle detection sensors to collect particle measurement values in a plurality of particle bins collecting particles of different sizes, generate a histogram representing the particle measurement values and determine based on a comparison of the histogram with a profile histogram for a pollutant, a match quality indicative of whether the pollutant is present in the environment. In various embodiments, a location of a pollutant is also determined according to the determined match quality.

Pollutant sensor device, system and method

A system, device and method facilitate accurate detection of gunshot events through spectrum analysis of impulse signals and/or evaluating impulse signal exponential decay amplitude and time values. In various embodiments, the device and system employ an acoustic sensor, one or more high-pass and low-pass filters, a threshold detector, a differentiator, a decay waveform shape generator, one or more comparators and one or more timers to facilitate detection of gunshot events and/or components of gunshot events.

Gunshot detection device, system and method

A sensor device, system and method can generate a profile of one or more detected substances in an environment, receive monitoring data from one or more of a group of sensors, and assess whether a heat-not-burn device activity event has been detected. In various embodiments, the sensor device includes a particle detection sensor and a gas detection sensor and a profile for heat-not-burn device activity is established with a threshold of detected particles and/or gases. In various embodiments, the profile for heat-not-burn activity is established with a threshold of gases that is not to be met or exceeded in order to generate a positive heat-not-burn detection.

Heat-not-burn activity detection device, system and method

Embodiments of a sensor device, method and system employ a multiplicity of environmental sensors as a single monitoring and alerting mechanism, operable to provide a profile of any contaminant in terms of various gases and particles in the atmosphere, quantified in terms of relative concentrations. In various embodiments, the sensor device can comprise hardware and firmware elements, including an electronic control system, a case, a shield and a cover. The environmental sensors can be secured as part of the electronic control system and the shield can be formed so as to facilitate proper channeling of air and sound for effective operation.

Sensor device and system

A railroad signal system interlocking is automatically tested. A control point interface corresponding to a predetermined function of the interlocking has an isolated section and a control section. The isolated section is connected with the interlocking and has a normal, inactivated state during operation of the interlocking, and an activated state for testing the interlocking by detecting an electrical characteristic representing the status of the predetermined function executed by the interlocking. The control section drives the isolated section to its activated state and receiving an output from the isolated section in response to the detected electrical characteristic, and delivers a status report.

Method and apparatus for automatically testing a railroad interlocking

A testing interface provides rapid, temporary connections to individual signal relays used in railroad signal systems when testing is required, and otherwise permits normal operation of railroad signal vital circuits through its connections. A connectivity block provides contacts that are used to isolate the relay from its application circuit and provide connectivity to the relay coils for testing when a connection paddle is inserted into the block. The interface allows fully automated or manual testing of installed relays without requiring removal from the relay rack.
