It is very critical that a non-invasive technology is adopted for continuous, painless, bloodless acquisition of physiological signals. For example, for monitoring oxygen saturation, red light (wavelength of 660nm) and infrared light (wavelength 910nm) are generated from the physiological sensor S1 and projected onto the user's forehead, which are then reflected back to the physiological sensor S1.

  • the strength of the signals from different spots of a person's forehead could vary substantially. Furthermore, signal strength could degrade due to inappropriate wearing.
  • the use of multiple receivers, as described previously, could partially address this problem of signal blind spot and degradation.
  • Figure 7 shows a transmitter 111 surrounded by three receivers 1 12. Similar to the description on the embodiment shown in Figure 6, the underlying idea is to compare the signals received by the three receivers and select the receiver with the strongest signal. Following the same principle, Figure 8 shows a transmitter 11 1 surrounded by four receivers and Figure 9 shows a transmitter 11 1 encircled by eight receivers. These designs are to improve the flexibility of positioning the device and the comfort and convenience of wearing it.

  • Motion related information such as exercise intensity and duration, can not only be used to analyze the wearer's lifestyle, exercise patterns, and health plans, but also the wearer's health status.
  • the movement detection system also includes an intelligent algorithm for detecting accidental falls, which is expected to be valuable for elderly users who have a high risk of fall.
  • Figure 17 is a flow diagram showing the process that the physiological and motion signals from the physiological and motion sensors are assessed systematically to generate warning and alerting messages related to the wearer's health conditions.
  • the device implements an expert system diagnosing the wearer's health status based on the physiological and motion information and this process continues over time. If the device detects a need to attend the wearer's health status, it would generate a warning or alert to the wearer through voice output. If a serious or dangerous health problem is detected, the device would generate a notification to the cell phone or PDA via its short-range radio frequency technology (RF), which will then send a notification to the health centers, doctors or family members, at the same time inform the wearer through voice output.
  • RF radio frequency technology
  • the wearer feels that he/she can deal with the crisis, he/she may choose to cancel the emergency request. Therefore, only when the wearer feels the need, or has lost the ability to cancel the emergency notification, the mobile phone or PDA will initiate emergency call and transmission of relevant health information.
  • the wearer's health state is often closely related to his/her physical conditions; as a result, by examining the physiological and physical signals together the underlying detection system becomes more intelligent and reliable. For example, under a normal resting condition, a heart rate of 60-100 beats per minute is normal for a wearer and a sudden increase of heart rate (e.g., over 120 beats per minute) would indicate some health related problems. However, if the wearer is detected to have changed his/her state of motion, such as from resting to running, then such increase in heart rate can be considered as normal as vigorous exercise often causes the heart rate to increase unless the increment amount exceeds a threshold. If a significant decrease in heart rate could also be an indication of health situation. Another example is arrhythmia with arrest or irregular beating for a period of time, indicating heart problems.
  • the contact sensor 23 is used to ensure that the device is worn properly and the sensor is placed at the specified spot for acquiring physical and/or motion signals. Inappropriate wearing or positioning could have a negative impact on the stability and quality of the signals being acquired and thus the reliability of the monitoring process. Once the device detects it is not worn or positioned properly, it would issue a voice warning such as a long beep or direct voice instructions.
  • the monitoring device According to the health status detected by the monitoring device, a variety of actions can be triggered, such as an emergency call or data transmission in a very serious situation and intelligent speech output for situations that need attention.

However, regardless the data collection frequency set by the user, the system will automatically increase sampling frequency when a health problem is detected. Therefore the system can run either under a power saving mode or a continuous mode, depending on the necessity.
  • the user cancellation key 32 shown in Figure 4 is used by the wearer to cancel an emergency outgoing call generated by the monitoring system. This function is necessary to reduce the likelihood of false alarms.
