Abstract:
The invention provides automatic control of a deep brain stimulation system (2) using tremor detection based on accelerometer signals. Because no manual interventions are necessary, the ease of use for the patient (1) is greatly enhanced. Furthermore the autonomy of the patients in normal daily life is increased. The present invention also results in a reduced energy consumption and consequently longer battery life. On the other side with the present invention an optimal treatment is possible, adjusted to the patient's symptoms without the help of a physician.
Abstract:
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).
Abstract:
The invention relates to a monitoring device (105) for remotely monitoring a heartbeat of a subject, the monitoring device comprising a remote sensor (102) for receiving a monitored signal (103) indicative of a movement of the subject's thoracic wall (101) induced by the subject's heartbeat. In an embodiment of the invention, the monitoring device (105) further comprises a triggering device (401) arranged to access the monitored signal (403) to generate a triggering signal (402) representative of a phase of the heartbeat. The invention further relates to an imaging or spectroscopy system (901), for example a magnetic resonance or computed tomography system or a cardiac 3D X-ray angiography system, arranged to acquire data from a subject, the system comprising such a monitoring device (105), wherein the system is further arranged to utilize the triggering signal (402) to synchronize the acquisition of the data to the phase of the subject's heartbeat.
Abstract:
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.
Abstract:
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.
Abstract:
The invention also relates to an optical sensor for a photoplethysmography measurement, comprising a light unit 1 with a light emitter 2 for emitting light into tissue of a patient 8 and/or a light detector 3 for detecting a part of the emitted light after interaction with the tissue, wherein the light unit is embedded in an elastic material 4. The invention further relates to a device for contactless respiration monitoring of a patient 8, comprising: a distance sensor for consecutively detecting the temporal distance variations relative to the patient's chest 12, preferably based on electromagnetic waves; and a calculating unit for determining the breathing activity based on the detected temporal distance variations. The invention is especially useful for providing a reliable and easy to use possibility for simultaneously monitoring respiration action, blood pressure and heart rate with a handheld device which can be used for spot- checking the vital parameters of patients in hospitals.
Abstract:
The present invention relates to an electrode for acquiring physiological signals of a recipient. Furthermore the present invention relates to a textile fabric for use in a garment to be worn by a recipient, and to a monitoring system for monitoring of physiological parameters of a recipient. In order to provide an electrode for acquiring physiological signals of a recipient, which on the one hand provides a soft, and comfortable skin contact, whilst on the other hand assures a high signal quality, an electrode (1) for acquiring physiological signals of a recipient is suggested, which comprises at least two conductive textile layers (2, 3) positioned on top of each other, wherein the first layer (2) is made of a woven material, and the second layer (3) having a working surface (4) to be brought into contact with the recipient's skin is made of a knitted material.

Abstract:
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.
