A detection device is connected to a plurality of communication devices by a communication line. The detection device has a reception unit, a measurement unit, and a detection unit. The reception unit receives signals with prescribed pulse widths transmitted from the plurality of communication devices, respectively. The measurement unit measures the pulse widths of the signals received by the reception unit. The detection unit is configured to detect the communication device disposed near a terminal end of the communication line as a terminal-end communication device on the basis of the plurality of pulse widths measured by the measurement unit.

Embodiments of the present invention relate to methods, devices, and systems to monitor activity. One method to monitor activity includes monitoring activity of an individual including detecting a sensor activated by an individual during the individual's daily activities. The embodiment also includes comparing the sensor activation to a predetermined sensor activation timeframe, determining whether to initiate an alert based upon the comparison, and checking for at least one other sensor activation to confirm whether an alert should be initiated.

Methods, systems, and apparatuses for integrating medical device data are disclosed. In an example embodiment, an integration engine includes a configuration interface configured to receive a patient identifier. The integration engine also includes a subscription processor configured to transmit a first message, including the patient identifier, to a first gateway to receive infusion therapy progress data from at least one infusion pump and transmit a second message, including the patient identifier, to a second gateway to receive renal failure therapy progress data from at least one renal failure therapy machine. The integration engine further includes a data processor configured to receive the infusion therapy progress data from the first gateway, receive the renal failure therapy progress data from the second gateway, and cause a combination user interface to display the infusion therapy progress data and the renal failure therapy progress data.

According to one aspect, a method includes obtaining a first signal from a host at an air mover system, the air mover system including an air mover and a tachometer, the tachometer having an associated tachometer signal. The method also includes determining whether the first signal is a request for information associated with the air mover, and providing the information from the air mover system to the host on the associated tachometer signal when it is determined that the first signal is the request for information associated with the air mover.

A method for protecting a nonmobile work machine driven by an electric motor includes determining, via a measuring unit, at least one measured value of a time-critical parameter of the work machine. The work machine is switched off when the determined measured value of the time-critical parameter is outside a predefined setpoint range. The determined measured value of the time-critical parameter is quantized in a level signal and transmitted as a first signal to an evaluation unit via an interface, and a second signal for further information concerning the work machine, to be transmitted from the measuring unit to the evaluation unit, is modulated to the first signal.

A wireless sensor system includes a wireless sensor node with a sensor interface that interfaces with sensing circuitry, a wireless interface to communicate with a wireless access point, at least one processor, and memory having instructions stored thereon that, when executed by the at least one processor, cause the wireless sensor node to set a heartbeat message rate to a first heartbeat message rate. Heartbeat messages are sent periodically at the first heartbeat message rate, and sensor data are acquired through the sensor interface. The heartbeat message rate increases to a second heartbeat message rate based on a determination that the sensor data have been acquired and are ready to transmit. The sensor data are transmitted in one or more heartbeat messages at the second heartbeat message rate until all sensor data have been transmitted, then the heartbeat message rate is returned to the first heartbeat message rate.

A multi-function thermostat for a building includes a communication interface and a processing circuit. The communications interface is configured to communicate with an emergency server and receive occupant health data from one or more health sensors configured to monitor an occupant of the building. The processing circuit is configured to determine a health metric associated with the occupant based on the occupant health data and cause the communications interface to send a distress message to the emergency server when the health metric associated with the occupant indicates a medical emergency.
