  • Publication number: 20250082530
    Abstract: A time-based wireless pairing operation between a medical device, such as a patient bed, and a wall module in a patient room is initiated in response to a power plug of the medical device being plugged into a power receptacle carried by the wall module. Times determined by timers of the medical device and the wall module are compared by the wall module or by the medical device so that wireless pairing occurs only with the medical device that was plugged into the wall module. Different types of plug detectors used in the wall module to detect connection of the power plug include optical detectors, mechanical switches, and current sensors.

  • Patent number: 12210629
    Abstract: Methods, systems, and computer programs are presented for automatic evaluation of security incidents. One method includes receiving a resolution status, for a set of insights, indicating if each insight was a true or a false positive. A global training set, comprising the resolution status for the insights, is generated, and a local training set with a subset of the insights associated with a first user. A machine-learning (ML) program is trained, using the global training set, to obtain a global model, and using the local training set to obtain a local model for the first user. When a new insight for the first user is detected, a global score is obtained using the global model, and a local score is obtained using the local model. A confidence score, calculated based on the global and local scores, is presented as an indication of an estimated severity of the new insight.

  • Patent number: 10162369
    Abstract: A liquid level control module comprising an elongated tubular housing immersible through a surface of a liquid and into a bulk volume of the liquid, and first, second, and third electrical switches, and first and second floats movable along the tubular housing. The first electrical switch is disposed within a lower portion of the tubular housing, the second electrical switch is disposed within an intermediate portion of the tubular housing, and the third electrical switch is disposed within an upper portion of the tubular housing. Each of the switches has an open state and a closed state. Motion of the first float relative to the first switch changes its state. Motion of the second float relative to the second switch changes its state, and motion of the second float relative to the third switch changes its state. Thus a two-float module may provide three level control signals.
