摘要:
An electrical device with an impedance detector comprises a path from a supply voltage to a second voltage. The path comprises segments having electrical impedances, at least one of which is to be ascertained, and a measuring vertex. The impedance detector further comprises a discriminator connected to the measuring vertex, arranged to evaluate a measuring voltage observed at said measuring vertex, and situated in a path between a further supply voltage and a third voltage. The discriminator draws no significant current from said supply voltage if the to be ascertained impedance remains above a threshold value. In this manner, in a standby mode, a zero-power supervision of a condition when to resume operation can be achieved.

An electrophysiological device comprises a lead-off detector in the form of an electrical impedance detector and further a path from a supply voltage to a second voltage. The path comprises segments having electrical impedances, at least one of which is to be ascertained, and a measuring vertex. The electrical impedance detector further comprises a discriminator connected to the measuring vertex and arranged to evaluate an electrical measuring signal observed at the measuring vertex.

The invention relates to a device, in particular a patient monitoring system with a mobile terminal unit ( 1 ) for acquiring patient data. The measured data is transferred from the terminal unit ( 1 ) via a short-range radio technology ( 2 ) (e.g. Bluetooth) to a data monitor ( 3 ) arranged at the patient's bedside when the patient is in the vicinity thereof. If necessary, communication can be switched to a long-range radio technology ( 7 ) (e.g. WLAN) to ensure interruption-free data transmission while the patient moves around.

The invention relates to a method of ensuring the quality of service in a broadcast network ( 1 ) which also comprises apparatuses (Q, Z) that do not have their own quality of service functionality. An apparatus operating as a bandwidth manager (BM) monitors the data traffic in the network and, in the case of risk of the ensured quality of service, it sends control messages (A) to the source (Q) of the data stream, which messages cause this source to reduce the data stream. The control messages (A) can be particularly transmitted through the simulated transmitter of the target (Z).

In a tracking method for tracking a local wireless device in a medical facility having a medical facility network (10), the local wireless device (50, 51, 52), which is not connected with the medical facility network (10), is detected based on local wireless communication. (54, 55, 56, 58) between the local wireless device and at least one nearby network device (12, 14, 16) that is connected with the medical facility network. A location of the local wireless device within the medical facility is estimated based on the local wireless communication and information indicative of a location of the at least one nearby network device.
摘要:
The invention relates to an emergency response system. The emergency response system (10) comprises a central station (4) for receiving information about emergencies, whereby position information of a victim is provided and stored in a look-up table (6) of the central station (4). The central station addresses a list (7) of publicly available actuatable emergency response devices and selects a suitable device. The central station (4) transmits a trigger signal by means of a suitable communication network (3) to the selected remote actuatable emergency response device (14), which comprises communication means (13) for activating the signaling means (15) upon receipt of the trigger signal. Also, the actuatable emergency response device (14) comprises storage means (11) arranged to store the position information of the emergency response device and the provided position information of the victim. Upon receipt of a suitable signal from the communication means (13), the signaling means (15) start broadcasting a message arranged to attract as many potential emergency responders to the victim as possible. The emergency response device (14) comprises navigation means (20), arranged to provide a routing to the victim, which is being fed-back to the responder by the user interface. The invention further relates to an emergency response device and a method for summoning an emergency responder and for routing said responder to the victim.
