Abstract: A building management system (BMS) for a medical facility that includes a plurality of rooms with at least one of the rooms having a plurality of sensors. An elevated infection risk determination system is operatively coupled to the plurality of sensors for determining when an elevated infection risk occurs in one or more of the rooms. The BMS may include a memory for storing one or more programmable infection risk compliance parameters, an input port for receiving an elevated infection risk alert for the particular room in the medical facility, a control port for providing control commands to one or more building components of the building management system, and a controller. The controller may be configured to provide control commands via the control port in response to receiving the elevated infection risk alert for the particular room based at least in part on one or more programmable infection risk compliance parameters to help mitigate the elevated infection risk in the particular room.

Abstract: A sensor assembly includes a housing, a sensor, and a transmitter. A power supply is configured to power the sensor assembly. A light harvesting element is configured to convert incident light into electrical energy for replenishing the power stored by the power supply. A controller activates and deactivates the sensor in accordance with a first activation schedule. The controller monitors a power reserve parameter of the power supply. When the power reserve parameter drops below a first power reserve threshold, the controller alters the activation schedule to a second activation schedule for the sensor that reduces power consumption from the power supply. After the light harvesting element replenishes the power stored by the power supply above a second power reserve threshold, the controller alters the activation schedule to return to the first activation schedule.

Abstract: A signal is received from an occupancy sensor each time a person passes through an access point corresponding to a building space, and is identified as indicating a person either entering or exiting the building space. An occupancy count is maintained for each of the building spaces by incrementing the occupancy count when the signal indicates a person entering and decrementing the occupancy count when the signal indicates a person exiting. A determination is made as to whether the occupancy count for any of the building spaces of the plurality of building spaces has reached a threshold for the corresponding building space. Action is taken in response to determining that the occupancy count for any of the building spaces of the plurality of building spaces has reached the threshold for that particular building space.

Abstract: A system for controlling one or more components servicing a space of a building based on an occupancy status of the space. The system may comprise a motion sensor, a person sensor for detecting each person passing through an access to the space, and a controller operatively coupled to the motion sensor and the person sensor. The controller may be configured to monitor the motion sensor for detected motion in the space, monitor the person sensor and maintain a people count of people currently in the space. The controller may use the detection of motion and/or the people count to determine if the space is occupied or unoccupied. The controller may then control one or more of the components servicing the space in a first control mode when the space is determined to be occupied and in a second control mode when the space is determined to be unoccupied.

Abstract: A computer assisted method for processing output from a mmWave sensor to derive a more reliable count of people in a room, zone or space being monitored by the sensor. In some examples, damping is applied to a varying “people count” signal from the sensor. The damping reduces volatility of the people count and avoids counting anomalous false positive detections. When the people count value decreases, damping may be applied more heavily to disregard intermittent false negatives where the sensor momentarily fails to detect an actual person. In some examples, the mmWave sensor provides point clouds representing the approximate shape and location of detected apparent objects, some of which may be people. Some example methods define digital targets corresponding to the point clouds. The targets are deemed to represent real people if the objects and their corresponding targets have sufficient lifespan and exhibit movement within a predetermined normal range.

Abstract: Methods and systems for monitoring procedural compliance of staff in a facility. One or more defined procedure to be performed by staff in a room of the facility are stored in a memory. The defined procedure(s) may include one or more conditions that must be met for the procedure to be considered as performed correctly. The one or more conditions may include visiting a defined procedure location in the room. The location of the person in the room may be identified by triangulating one or more signals emitted by a device carried by the person and/or transmitting one or more signals into the room and receiving one or more corresponding reflected signals reflected off the person in the room. The method and/or system may determine whether the one or more conditions of the defined procedure have been met, and if not, issue an alert.

Abstract: The invention relates to a system for low data-rate communication over a modulated direct carrier current, having one or more communication transmitters (6, 8), a communication receiver (10), and a wire bus (12) forming a shared transmission channel. Each communication transmitter (6, 8) is configured to form a first raw staggered transmission frame according to a second staggered transmission frame, said staggered transmission frames using a set of separate basic chip-encoding sequences. The basic encoding sequences or staggering the symbols used by all the communication transmitters (4, 6) are identical, and the times of the initial transmission of the second staggered frames produced by each transmitter (6, 8) are autonomously and freely determined by each transmitter (6, 8), without taking into account any synchronization signal external to the transmitter (6, 8).
