The invention provides a system and method for measuring vital signs (e.g. SYS, DIA, SpO2, heart rate, and respiratory rate) and motion (e.g. activity level, posture, degree of motion, and arm height) from a patient. The system features: (i) first and second sensors configured to independently generate time-dependent waveforms indicative of one or more contractile properties of the patient's heart; and (ii) at least three motion-detecting sensors positioned on the forearm, upper arm, and a body location other than the forearm or upper arm of the patient. Each motion-detecting sensor generates at least one time-dependent motion waveform indicative of motion of the location on the patient's body to which it is affixed. A processing component, typically worn on the patient's body and featuring a microprocessor, receives the time-dependent waveforms generated by the different sensors and processes them to determine: (i) a pulse transit time calculated using a time difference between features in two separate time-dependent waveforms, (ii) a blood pressure value calculated from the time difference, and (iii) a motion parameter calculated from at least one motion waveform.

A system for allowing a player to invoke magic or other special powers in a video game is provided. To activate the magic, the player moves a motion detecting controller in accordance with one or more provided instructions. The outcome of the activation of the magic can be determinate on, for example, speed, accuracy, etc. Controllers in one or both hands may be used, and the instructions can be as simple as single direction gestures and as complex as multi-directional symbols which must be traced in the air. A sequence of any type of instructions may also be provided to instruct the activation of the magic.

The invention provides an audition and vision collaborative humanoid robot head orientation method. The method is characterized by mainly comprising the following steps of firstly, acquiring a voice signal through a microphone array and recording time; recognizing by using a human voice recognition method, and counting the number of microphones for collecting human voice; setting a candidate target orientation according to time when the number of the voice microphones is greater than 1; then rotating a camera and acquiring a video; obtaining human face image frames from the video, obtaining a human face recognition result through recognition by means of a human face recognition method, and counting the number of human faces; when the number of the human faces is greater than 1, calculating human face areas and sorting the human face areas; setting candidate target human faces according to the ranking; then, achieving lip movement recognition through a lip movement detection algorithm; setting a target orientation according to the area when the number of the human faces with lip movement is greater than 1; and finally rotating the head of the humanoid robot to realize orientation. According to the method, the humanoid robot can distinguish the human voice from other voices and can accurately interact with the target human voice.
