Pulse oximeter
InactiveUS6912413B2Improve performanceMinimize powerDiagnostic recording/measuringSensorsBlood oxygenationPulse oximetry
The invention relates to pulsed oximeters used to measure blood oxygenation. The current trend towards mobile oximeters has brought the problem of how to minimize power consumption without compromising on the performance of the device. To tackle this problem, the present invention provides a method for controlling optical power in a pulse oximeter. The signal-to-noise ratio of the received baseband signal is monitored, and the duty cycle of the driving pulses is controlled in dependence on the monitored signal-to-noise ratio, preferably so that the optical power is minimized within the confines of a predetermined lower threshold set for the signal-to-noise ratio. In this way the optical power is made dependent on the perfusion level of the subject, whereby the power can be controlled to a level which does not exceed that needed for the subject.

Two-directional bar code symbol and its encoding & decoding method
InactiveUS20070272755A1Lower requirementEasy to readCo-operative working arrangementsRecord carriers used with machinesDecoding methodsImaging processing
This present invention discloses one type of two-dimensional bar code and its encoding and decoding method. The two-dimensional bar code is represented as circular element modules (CEMs), between which there are spaces. As a CEM remains a CEM after deep defocusing imaging, it can be restored well to be the same shape as that of a CEM after the filtering by the Unsharp Mask. This design enables the image processing algorithm to become insensitive to the selection of the binarization threshold value. Since there is space between modules, it is less likely that the adjacent modules will stick together after binarization so that each module can be positioned independently. The present invention is very reliable for reading and decoding even under imaging conditions of deep defocusing and low illumination. Its features include easy-to-read, strong error correction capability and low requirement for reading devices, which makes it a potential popular application.
