A selective input system and associated method is provided which tracks the motion of a pointing device over a region or area. The pointing device can be a touchpad, a mouse, a pen, or any device capable of providing two or three-dimensional location. The region or area is preferably augmented with a printed or actual keyboard/pad. Alternatively, a representation of the location of the pointing device over a virtual keyboard/pad can be dynamically shown on an associated display. The system identifies selections of items or characters by detecting parameters of motion of the pointing device, such as length of motion, a change in direction, a change in velocity, and or a lack of motion at locations that correspond to features on the keyboard/pad. The input system is preferably coupled to a text disambiguation system such as a T9® or Sloppytype™ system, to improve the accuracy and usability of the input system.

The invention discloses a multi-camera intelligent control method and a device. The method comprises the following steps: detecting a moving target in a video signal; analyzing the size, position and moving parameters of the moving target in an image; controlling the orientation and the focal length of the camera according to the size, position and moving parameters of the moving target and leading the moving target to be displayed in a video picture of the camera in appropriate position and size so as to realize the tracking of the moving target; predicting the monitoring area to be entered of an adjacent camera by the moving target according to the position and moving direction of the moving target and the monitoring range of the adjacent camera, and controlling the position and focal length of the adjacent camera, so as to lead the viewing field of the adjacent camera to capture the moving target or wait the moving target for entering the viewing field. The invention can carry out full-range cross-camera automatic tracking to the moving target in the monitoring area covered by the multi-camera and can utilize the moving target information of various cameras comprehensively, thus carrying out linked control to the cameras of the whole system.

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.

In a system for animating an object along a music, a sequencer module sequentially provides music control information and a synchronization signal in correspondence with the music to be played. A parameter setting module is operable to set motion parameters effective to determine movements of movable parts of the object. An audio module is responsive to the synchronization signal for generating a sound in accordance with the music control information to thereby play the music. A video module is responsive to the synchronization signal for generating a motion image of the object in matching with progression of the music. The video module utilizes the motion parameters to basically control the motion image, and utilizes the music control information to further control the motion image in association with the played music.
