摘要： A blood viscosity measuring system and method that monitors the rising head of a column of fluid representing a living being's blood in-vivo to determine the blood viscosity over a range of shears. The system includes a capillary tube, at least a portion of which is located within the vascular system of the being, and a riser tube, having a liquid therein coupled to the capillary tube. A sensor and associated microprocessor are provided to determine the change in the height of the liquid in the riser tube at plural points along the length of the tube from which the viscosity is calculated. The system can be utilized to determine the deformability of the red blood cells of a living being's blood and/or the thixotropic properties of a living being's blood. Use of the system enables one to screen a material, e.g., a pharmaceutical, on a test subject, such as a living human being or laboratory animal, to determine the likely effect of the material in altering a parameter of the blood, e.g., viscosity, red blood cell deformability, or thixotropic nature, of a living, e.g., human, being to which the material will ultimately be administered.

摘要： A wearable physiological signal detecting device includes a device main body and a telescopic structure. The device main body has a strap which surrounds to form a wearable space. The telescopic structure is disposed in the strap and has first surfaces and second surfaces. Each of the first surfaces faces the corresponding second surface. Each of the first surfaces and the corresponding second surface continuously move close and contact each other to assume a first state. The strap can be forced so that each of the first surfaces and the corresponding second surface move away from each other and have an angle to assume a second state. The size of the wearable space when the first surface and the corresponding second surface assume the second state is greater than the size of the wearable space when the first surface and the corresponding second surface assume the first state.

摘要： A capacitive accelerometer device is provided, and includes a capacitive accelerometer module, a display device and a signal line. The capacitive accelerometer module includes one or more capacitive accelerometers for sensing an arterial acceleration pulse wave of a user. The display device includes a displayer and a speaker. The displayer is used to display the arterial acceleration pulse wave of the user. The speaker emits an audible signal according to a change value of the arterial acceleration pulse wave. The display device electrically connects to the capacitive accelerometer module via the signal line. The display device automatically senses the arterial acceleration pulse wave of the user and correspondingly generates the change value. The display device generates a prompt signal when the change value is equal to or larger than a predetermined value.

摘要： A system and method monitoring conditions of a subject's body including a control unit receiving image data and data indicative of an external stimulation applied to the body during collection of the image data therefrom, a memory utility, and a processor utility. The image data is indicative of a sequence of speckle patterns generated by the body according to a certain sampling time pattern. The processor utility performs processing the image data utilizing the data indicative of the applied external field(s), including determining a spatial correlation function between successive speckle patterns in the sequence, and determining a time varying spatial correlation function in the form of a time-varying function of a feature of the correlation function indicative of a change of the speckle pattern over time; selecting a parameter of the time-varying spatial correlation function, and applying a model to the parameter to determine a corresponding body condition; and generating output data indicative of the corresponding body condition.
