A device and system for promoting more recuperative sleep by regulating a user's body temperature. This may be done by using a series of devices that measure information about the user both while they are awake and while they are asleep, communicate that information to a processing unit, and create an ideal body temperature range profile based on that information. A temperature stimulus device may ensure that the core body temperature of the user stays substantially within the ideal body temperature range. By keeping the core body temperature of the user within the calculated range, the device and system will ensure deeper, and therefore more recuperative, sleep.

A method for collecting and analyzing urine at the time it is released uses a urine collecting tube joined with a canister. Suction is produced in the collecting tube to join the tube with a penis or to the exterior surface of a female urethra orifice. Once suction is achieved the collecting tube stays in place by suction action. When urine flows into the urine collecting tube a sensor triggers a vacuum pump to produce a higher level of suction to flush the urine into the canister where a level sensor determines the quantity of urine received. Various sensors in the canister determine levels of non-urine partials such as occult blood, drugs, salt, and other substances. When urine is no longer detected within the urine tube, the vacuum pump is turned off and a low-level vacuum remains to assure interconnection with the urine tube.

A method for processing blood pressure measurement includes obtaining a facial feature point of an object, determining a first height difference between the facial feature point and an origin of a second coordinate system based on a first coordinate of the facial feature point in the second coordinate system and a first attitude angle of the second coordinate system relative to a first coordinate system, determining a third height difference between the origin of the second coordinate system and the heart of the object based on the first height difference and a second height difference, where the second height difference is a height difference between the facial feature point and the heart of the object, and determining blood pressure based on a blood pressure measurement signal of the object and the third height difference.

A chest non-invasive blood pressure detecting probe based on pulse wave transit time and a device thereof are provided. The detecting probe is attached closely to the skin surface of the human chest, and includes a probe body and a patch, which are of split type. The patch is attached and mounted, in a male-female fastener form, on the probe body for use, so that when the patch needs to be replaced, the patch is directly removed and replaced with a new patch, which is convenient for use. The detecting probe is portable and used for continuous dynamic real-time acquiring of the human aortic blood pressure, which is free from the constraints of lead wires, small and comfortable, and high in measuring precision.

A non-pressure continuous blood pressure measuring device, comprises: a radar sensing module, an electro-cardiac sensing module and a microprocessor. The radar sensing module includes at least a transmitter and a receiver, the transmitter continuously provides a pulse wave signal to an artery, the receiver receives a reflected pulse wave signal. The electro-cardiac sensing module includes at least an electrode; the electro-cardiac sensing module receives an electro-cardiac signal through the electrode. The microprocessor is in signal transmittable connection with the radar sensing module and the electro-cardiac sensing module. The microprocessor controls the radar sensing module and the electro-cardiac sensing module, and simultaneously receives the reflected pulse wave signal and the electro-cardiac signal. The microprocessor determines a blood pressure parameter of the artery according to the reflected pulse wave signal and the electrocardiography signal.

A patch-type sensor module is provided. A patch-type sensor module according to one embodiment of the present invention comprises: a power supply unit electrically connected with a flexible circuit board; a sensing unit which is mounted on the flexible circuit board and includes a temperature sensor for measuring a user's body temperature; a communication unit which allows power to be supplied using a wake-up function, wherein a pairing with an external communication module is concurrently established when power is supplied, and information measured through the sensing unit is then transmitted to the external communication module; a control unit for controlling operations of the power supply unit, the sensing unit, and the communication unit; and a protection member for preventing the flexible circuit board, the power supply unit, the sensing unit, the communication unit, and the control unit from being exposed to the outside.
