A heart lung machine (HLM) includes: a pump actuator; an actuator control unit (ACU) operably connected to the pump actuator; a processing unit configured to receive a set of parameter data from the actuator; a display device configured to present a subset of the set of parameter data; and an input control device operably connected to the pump actuator. The input control device includes a rotatable knob. The ACU may be configured to: determine that the pump actuator has been stopped in response to a pump-stop trigger event; determine that the rotatable knob has been rotated to a first position; and in response to determining that the rotatable knob has been rotated to the first position, starting the pump actuator.

A proximity warning system including cameras positioned on a machine, processors, and one or more memory devices including instructions for execution by the processors. The system includes instructions to receive, from the cameras, image data depicting an object within a field of view of the cameras. The system includes instructions to derive a first distance between the object and the machine based on the image data and an alarm is triggered when the first distance is less than a first threshold distance. The system can include instructions to receive a request to snooze the alarm and discontinue the alarm. Additional image data can be received from the cameras and a second distance between the object and the machine is derived based on the additional image data. The system includes instructions to cancel the snooze and retrigger the alarm when the second distance is less than a second threshold distance.

Systems, methods, and computer program products for detecting, locating, and identifying gunshots. In response to detecting a discharge of a firearm, a discharge alert indicating one or more characteristics of the discharge is transmitted to a gunshot location system. The one or more characteristics of the discharge are compared to one or more characteristics of one or more gunshots detected by the gunshot location system based on acoustic signals received at one or more listening stations. In response to finding a match between the one or more characteristics of the discharge and the one or more characteristics of acoustically detected gunshot, the gunshot is associated with the firearm.

In some implementations, a system may identify a plurality of sensor devices that are associated with a physical environment. The system may receive an indication that a set of sensor devices (e.g., that includes two or more sensor devices) are to be associated with a virtual sensor that is associated with the physical environment. The system may generate, based on receiving the indication, the virtual sensor. The system may obtain sensor data that was captured by the set of sensor devices. The system may process the sensor data to determine a set of parameters associated the virtual sensor. The system may determine, based on the set of parameters associated with the virtual sensor, that a physical environment condition is satisfied. The system may cause, based on determining that the physical environment condition is satisfied, one or more actions to be performed.

An unmanned preview system that enables an unmanned preview of a building without requiring presence of an agent and can suppress damage or the like inside the building, wherein an unmanned preview system includes: a preview robot that is configured to be placeable inside the building and has portability; and a management device that is connected to the preview robot via a communication line and manages the preview robot. The preview robot includes an abnormality notifier that notifies the management device of an abnormality via the communication line when the abnormality having occurred inside the building is detected. The management device includes an abnormality annunciator that announces the abnormality to an administrator when it is notified of the abnormality by the abnormality notifier.

A method for controlling a virtual meeting includes receiving a meeting template including at least one rule. The rule or rules associated with the meeting template define a first time period relating a first virtual meeting session of a first endpoint computing device and a second time period relating to a second virtual meeting session of a second endpoint computing device. The method further includes causing, responsive to the rule(s), a first audio mute/unmute action to occur in the first virtual meeting session at or prior to an expiration of the first time period. The method further includes causing a second audio mute/unmute action to occur in the second virtual meeting session at or prior to a start of the second time period, where the second time period is different from with the first time period.
