Systems and methods to provide a portable alarm, are disclosed herein. The system may include a top component that includes a connector, a first securing protrusion, and a second securing protrusion that extend out a bottom side of the top component; and a base component that includes a narrow cavity, a first notch, a second notch, and a battery-powered circuit board, the first securing protrusion, the second securing protrusion, and the connector engaging with or otherwise connecting with the first notch, the second notch, and the narrow cavity, respectively, to provide secure contact between the top component and the base component, the narrow cavity is linked to the battery-powered circuit board so that responsive to the connector being disengaged from the narrow cavity, an alarm is activated and responsive to the connector being engaged with the narrow cavity, the alarm is deactivated.

An electrical safety device is described which includes a socket arranged to receive an electrical plug of an electrical appliance to connect a current supply to the electrical appliance, a thermal sensor arranged to detect the surface temperature of an electrical plug when received in the socket and a processor in communication with the thermal sensor, the processor configured to determine when the sensed surface temperature exceeds a predetermined threshold. The invention also includes an electrical safety system comprising the electrical safety device configured to communicate with a remote device. The device and system provide early detection of electrical faults and hazards to reduce the risk of fires.

Disclosed herein is a method of determining the nature of a fault in a radiotherapy device comprising a linear accelerator. The radiotherapy device is configured to provide therapeutic radiation to a patient. The radiotherapy device comprises a vacuum tube comprising an electron gun, a waveguide configured to accelerate electrons emitted by the electron gun toward a target to produce said radiation, and a flight tube. The electron gun is located at a first end of the vacuum tube and the flight tube is located at a second end of the vacuum tube. The radiotherapy device further comprises a first and a second sensor. The first sensor is configured to provide signals indicative of pressure at a first region inside the vacuum tube and the second sensor is configured to provide signals indicative of pressure at a second region inside the vacuum tube. The first region is closer to the first end of the vacuum tube than the second region is. The method comprises processing a first value derived from signals from the first sensor and a second value derived from signals from the second sensor. The first value is indicative of pressure at the first region inside the vacuum tube, and the second value is indicative of pressure at the second region inside the vacuum tube. Processing the first and second value comprises comparing the first value with a first threshold and comparing the second value with a second threshold; and, based on the processing of the signals, determining that the nature of the fault is associated with the flight tube.

In one embodiment, a video analysis service receives video data captured by one or more cameras at a particular location. The service applies a neural network-based model to portions of the video data, to identify objects within the video data. The service maps outputs of the neural network-based model to symbols using a conceptual space. The outputs of the model comprise the identified objects. The service applies a symbolic reasoning engine to the symbols, to generate an alert. The service sends the alert to a user interface in conjunction with the video data.
