A computing system may identify a surgical instrument for a surgical procedure in an operating room (OR). The computing system may detect a control input by a health care professional (HCP) to control the surgical instrument. The computing system may determine the HCP's access control level associated with the surgical instrument. The computing system may determine whether the HCP has an authorization to control the surgical instrument. If the computing system determines that HCP is unauthorized to control the surgical instrument based on the access control level associated with the HCP, the computing system may block the control input by the HCP. If the computing system determines that the HCP is authorized to control the surgical instrument based on the access control level associated with the HCP, the computing system may effectuate the control input by the HCP to control the surgical instrument.

An atmospheric pollution emission control effect evaluation method, device and storage medium, including: carrying out meteorological condition frequency statistics of data collected from meteorological station, obtaining meteorological condition frequency distribution information; obtaining pollutant concentration information, performing pollutant concentration distribution statistics to obtain pollution concentration distribution information and pollution concentration variation information; decomposing effects of meteorological factors and non-meteorological factors according to meteorological condition frequency distribution information, pollution concentration distribution information and pollution concentration variation information, to obtain meteorological and non-meteorological contribution information; constructing source emission control effect evaluation data set according to meteorological condition frequency distribution information, pollution concentration distribution information, meteorological and non-meteorological contribution information. Accordingly, emission control effect can be quantitatively evaluated based on observation data. Emission increasing effect and contribution of meteorological changes to variation of average pollution level can be quantified.

The disclosed technology is generally directed to an audit ledger for externality tracking. In one example of the technology, auditing of a virtual sensor is enabled. The virtual sensor is configured to output an externality value based on received telemetry data. The externality values are associated with the at least one particular type of quantifiable technical externality. Signing of the virtual sensor is enabled. Audit information associated with the signing of the virtual sensor is stored on a ledger. Periodic aggregated externality values based on the externality values output by the virtual sensor are calculated. The periodic aggregated externality values are stored on a distributed ledger. An audit of the periodic aggregated externality values is enabled. The auditing of the periodic aggregated externality values includes verifying the signing of the virtual sensor by the auditor based on the stored audit information.

Systems, apparatuses, and methods for monitoring an environment are provided. One system includes a monitoring unit positioned within an environment and including an acoustic sensor configured to generate detected acoustic data regarding acoustics in the environment, and a controller having one or more processors and one or more non-transitory memory devices that store instructions for controlling the one or more first processors to receive and store the detected acoustic data, determine, based on the detected acoustic data, whether a noise is above a threshold, and determine, based on the detected acoustic data and that the noise is above the threshold, an estimated source of the noise.

Deleterious gas is captured from atmospheric air using capture units dispersed across a geographic region. Each unit has a filter that is capable of capturing compounds from the gas from air when air is passed through the filter by fans. The units additionally include a sensor for sensing a level of the gas in the air. An electronic processor controls the fan, and communicates data from the sensor to other units and/or a central electronic processor. The electronic processors of the units or the central processor controls the fan speed of units in areas of higher concentration of the gas, selecting which units to become active based upon a proximity of each unit to the gas concentration, as well as a direction of movement of the concentration. A communicated presence of errors or a low battery state of a unit, is used by the processor to select other units nearby for operation instead of the affected unit.
