Abstract: An optical measurement device includes a light source, a first detector, and a second detector. The light source emits light to a measurement site of a patient and one or more detectors detect the light from the light source. At least a portion of a detector is translucent and the light passes through the translucent portion prior to reaching the measurement site. A detector receives the light after attenuation and/or reflection or refraction by the measurement site. A processor determines a light intensity of the light source, a light intensity through a tissue site, or a light intensity of reflected or refracted light based on light detected by the one or more detectors. The processor can estimate a concentration of an analyte at the measurement site or an absorption or reflection at the measurement site.

Abstract: A quality control system for patient monitors is disclosed. The quality control system can include a quality check insert having optical properties. In an embodiment, the insert is placed within a sensor, irradiated with light, and then the light is detected after attenuation by the insert. The detected light is processed using the same or different processing methodologies typically used to determine measurement values for physiological parameters of a monitored patient. When a patient monitor is functioning properly, the results of the processing provide values within a predetermined range of values. When the patient monitor is not functioning properly, the results of the processing provide values outside the predetermined range of values. The quality control system can include quality control parameters indicative of a properly functioning active pulse motor of the sensor, emitters of the sensor, detectors of the sensor, accelerometers of the sensors, and/or temperature sensors of the system.

Abstract: A system is disclosed for detecting and calculating the level of ambient and/or environmental noise, such as electromagnetic interference generated by electric power lines, ambient lights, light dimmers, television or computer displays, power supplies or transformers, and medical equipment. In some embodiments, the system performs frequency analysis on the interference signal detected by light photodetectors and determines the power of the interference signal concentrated in the analyzed frequency bands. The worst-case interference level can be determined by selecting the maximum from the computed power values. In some embodiments, the determined interference signal power can be compared with the noise tolerance of a patient monitoring system configured to reliably and non-invasively detect physiological parameters of a user. The results of the comparison can be presented to the user audio-visually. In some embodiments, the system can be used to perform spot check measurements of electromagnetic interference.
