    摘要: 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.

    摘要: This invention relates to a system and a kit for stress and relaxation management. A cardiac activity sensor (101) is used for measuring the heart rate variability (HRV) signal of the user and a respiration sensor (102) for measuring the respiratory signal of the user. The system contains a user interaction device (103) having an input unit (104) for receiving user specific data and an output unit for providing information output to the user. A processor (106) is used to assess the stress level of the user by determining a user related stress index. The processor is also used to monitor the user during a relaxation exercise by means of determining a relaxation index based on the measured HRV and respiratory signals, the relaxation index being continuously adapted to the incoming measured signals and based thereon the processor instructs the output unit to provide the user with biofeedback and support messages. Finally, the processor uses the user specific data as an input in generating a first set of rules defining an improvement plan for self-management of stress and relaxation. The first set of rules is adapted to trigger commands instructing the output unit to provide the user with motivation related messages. Also, at least a portion of said user specific data is further used to define a second set of rules indicating the user's personal goals.

    摘要: Flash ROM memory may be utilized to enable field updates of system-level code necessary for providing system operation. However, a disruption during downloading can render a system inoperable. With alternating use of two memory areas, downloading is provided on a fault tolerant basis. A previously-stored functional code version is held in a first memory area. A second memory area is erased and an update code version is downloaded and stored therein. In case of unsuccessful downloading, the previously-stored functional code version remains usable. For the next downloading a later update version is loaded into the first memory area, while the previously downloaded update code version is held in the second memory area for use if needed. By this alternation of memory areas, one memory area can safely be erased or over-written for new code downloading, while an operationally validated prior version of the code remains available in case of downloading failure.

    摘要: The invention relates to a waveguide (24) for focusing electromagnetic energy on an area of interest, said waveguide (24) comprising outer walls forming a channel with a width (w) and a height (h) for the propagation of the electromagnetic waves. In order to be able to focus the EM waves on an area of interest, i.e. the chest of a patient (20), so that influences which other moving objects in the environment have on the waves, are shielded away, the channel is provided with a first opening and a second opening wherein said walls are non-metal hollow walls filled with an electrically conductive liquid. The waveguide (24) can be used for example with a computed tomography system (12) CT with a rotating gantry (16) and a patient table (18). The waveguide (24) will not produce artefacts in the CT image by scattering the X-ray, like a metal wall would do it. Nevertheless the conductive liquid makes the construction work as a waveguide for EM waves.
