Optical techniques for the measurement of chest compression depth and other parameters during cpr

Embodiments of the present invention are related to a method and device for the determination and calculation of the depth of chest compressions during the administration of cardiopulmonary resuscitation (CPR). Embodiments use an optical sensor to monitor the distance that a victim's chest is displaced during each compression throughout the administration of CPR. The optical sensor is most commonly an image sensor such as a CMOS or CCD sensor, and more specifically a CMOS image sensor capable of three-dimensional imaging based on the time-of-flight principle. An infrared emitter may illuminate the victim's body and any visible piece of ground beside the victim. As the infrared light interacts with any surfaces it encounters, it is reflected and returns to the image sensor where the time of flight of the infrared light is calculated for every pixel in the image sensor. The distance data is used to gauge the effective displacement of the victim's chest. The optical sensors can be used to visualize the size of a patient and immediately gauge the body type and instruct the user accordingly. Furthermore, optical measurement techniques can be used to accurately measure chest rise during artificial respiration and ensure that proper ventilation is being administered in between compressions. In addition, optical measurements of the chest of the victim and the hands of the rescuer can be used to help ensure that the rescuer has positioned his or her hands in the anatomically correct location for effective CPR.

The invention provides an Internet intelligent mirror based on a natural user interface. The Internet intelligent mirror mainly comprises a base, a square mirror frame, a filter single lens, a light emitting screen and a mainboard. The filter single lens, the light emitting screen and the mainboard are located in the square mirror frame. The filter single lens is located on one side, facing a user, of the intelligent mirror. The light emitting screen and the mainboard are located on the rear side of the filter single lens. The mainboard is located below the light emitting screen. A loudspeaker A, an infrared transmitter, a color camera, a depth sensor, a microphone and a loudspeaker B are sequentially disposed on the upper portion of the front side of the square mirror frame from left to right. During use, a user can interacts with the mirror through voices and gestures by facing the mirror, and experiences such as physical data measuring and virtual try on are achieved. The Internet intelligent mirror has the advantages that the mirror can understand human languages and the gestures of people; when the user faces the mirror, Internet information browsing can be achieved by voice control, virtual clothes can be tried on through gesture control so as to decide intraday wearing, and body bone motion trajectories can be recorded and analyzed to aid various exercises high in body posture requirements.

Automatic obstacle-avoiding method of robot cleaner and control method thereof

The invention relates to an automatic obstacle-avoiding method of a robot cleaner and a control method thereof. The robot cleaner comprises a dust collecting body, a base station and a control circuit. The dust collecting body is provided with a left wheel and a right wheel. The top of the base station is provided with an infrared emitter. The upper part of the dust collecting body is provided with an infrared receiver which receives an infrared communication signal emitted from the base station. The control circuit comprises a singlechip, a drive circuit, a current feedback circuit, an anti-dropping circuit, an infrared receiving circuit and a voltage monitoring circuit. The singlechip controls the operation of the robot cleaner according to the relative positions of the dust collecting body and the base station. When meeting obstacle, the singlechip judges and controls the dust collecting body to avoid the obstacle and next moving direction. After collecting dust for a period of time, the dust collecting body returns to the base station for pumping the dust and charging automatically. The robot cleaner manufactured by the invention has simple structure, reliable control and stable performance and can fulfill unattended intelligentized cleaning.

Photoelectronic control system for industrial sewing machine

The invention discloses a photoelectric control system for an industrial sewing machine, and relates to the technical field of photoelectric control, in particular to an infrared control system capable of detecting fabric edge length of materials sewn and whether sewing materials exist by an industrial sewing machine. The control system comprises two infrared emitters (1) independently forming a relative included angle (phi), an infrared receiver tube (2) and an infrared receiver tube (3) positioned in a front circular hole and a back circular hole of a needle plate holder, a cutter assembly (5), a fabric edge signal processor (10), an air suction pipe (11) and a sewing machine electric cabinet (17), and comprises steps of a to d. Two groups of signals about having or no fabric edges are provided to the fabric edge signal processor to be processed through judging whether the fabric edges are existed on a sewing machine needle plate; and starting, stopping, accounting, speed raising, speed reducing, wire cutting and air sucking and the like of the sewing machine are controlled automatically according to positions of the fabric edges supplied to a system controller. The control system has the characteristics of accurate output signals, good anti-interference property, easy processing and high performance cost ratio, is suitable for various industrial sewing machines, and the like.
