Abstract:
The present invention relates to a device and method for measuring a user's heart rate. In order to provide a reliable and inexpensive heart rate measuring technique, a device (1) and a method for measuring a user's heart rate is suggested in which the relative movement between a heart rate sensor (2) and the user is detected to generate a correction signal for removing motion artifacts caused by a user' s movement.
Abstract:
The present invention relates to a monitoring system for monitoring physiological parameters of a recipient, comprising at least one electrode having a working surface that is to be brought into a contact with the recipient's skin. To provide a user-friendly monitoring system with an improved measurement quality that is suitable for home use, a monitoring system for monitoring a physiological activity of a recipient is provided, the system comprising at least one dry electrode having a working surface that is to be brought into a contact with the recipient's skin, the system being characterized in that the at least one electrode comprises a flexible conductive shell that is to be integrated into a textile or a garment and an electronic circuit embedded in the shell. The invention is preferably used in the field of personal health care for continuous monitoring of electro-physiological parameters outside hospitals at maximum comfort.
Abstract:
In a medical pulse oximetry sensor (10) at least two light emitting diodes (16, 18) are disposed to emit red light and infrared light through a portion of a subject's anatomy with a typically high oxygenated blood throughput. Typically, this area is also relatively narrow, to allow the light to pass through the area with acceptable attenuation, such as a finger or an earlobe. Light emitted from the LEDs (16, 18) is incumbent upon an integrated circuit (22) printed from a single CMOS substrate (21). The integrated circuit (22) includes all preprocessing and post-processing elements needed to convert the detected light signals into a pulse oximetry measurement. These elements include a photodetector (20), a photo pre- amplifier (40), a sampler/holder (42), an analog to digital converter (44), a microprocessor (46) a rangefinder (48), a timing control circuit (50) and an LED control circuit (52). By integrating all pre and post processing functions into the carriage housing (12), the system becomes more efficient, less expensive to manufacture, and more robust to ambient light and x-ray radiation.
Abstract:
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.
