A toilet comprising a rinsing seat, a rimless bowl, and a helical loop trapway is disclosed. An annular cavity for the purpose of storing and dispensing rinse water from the rinsing seat is disclosed. In one embodiment, the rinsing seat includes a pressurized line which can be pressurized by a compressible membrane compressed by a toilet user. Outlet nozzles arranged about the circumference of the rinsing seat and designed to dispense rinse water at the rimless bowl are disclosed. Rinsing seat supports, hinge assemblies, and seat sensors which offer additional functionality to the rinsing seat are also disclosed. A steep interior surface and hydrophobic material for the rimless bowl are also disclosed and claimed herein.

According to one embodiment, a toilet seat device includes a toilet seat, and a Doppler sensor using radio waves. An opened state of the toilet seat is sensed when approach of a user to the toilet seat is sensed based on a sensing signal outputted by the Doppler sensor. It is regarded that use is in progress for urination by the user when the toilet seat is in the opened state. In a state of being regarded that use is in progress for urination, a post-use operation is performed after sensing leaving of the user from the toilet seat based on the sensing signal.

An image recognition automatic flip-top smart toilet mainly includes an image recognition chip provided on one side of the toilet facing the front structure of the user, and a controller and two power packs arranged inside the toilet. The image recognition chip is electrically connected to the controller, and the controller is connected to two power packs to control their individual actions. The first power pack is used to control the automatic lifting and closing of the toilet lid, and the second power pack is used to control the automatic lifting and closing of the toilet seat ring. When the image recognition chip detects that the user in front of the toilet is a non-frontal image, it will send a signal to the controller to enable the controller to activate the first power pack to lift the toilet lid, allowing the user to sit on the seat ring for use. When the image recognition chip detects that the user in front of the toilet is a frontal image, it will send another signal to the controller, so that the controller can activate the two power groups at the same time to lift the toilet lid and seat ring, allowing men to stand up without the need to touch with hands. It is then to achieve the convenience of safety and hygiene, to meet the requirements of intelligent living.

Apparatus, system and method for medical analysis of a seated individual, includes determining the aortic valve opening; the PTT; and calculating the PWV. Determining the aortic valve opening includes collecting BCG data while sitting on a seat and determining the timing of the aortic valve opening, taking into account posture. Measuring the aortic pulse wave transit time includes collecting BCG data while sitting on a seat capable of measuring changes in apparent weight; determining the timing of the aortic valve opening; detecting the arrival of the pulse wave at the end point; and measuring the relative timings of the two events. Calculating the PWV includes determining a length of the arterial segment through which a pulse wave is to be measured between a start point and an end point; and dividing the determined length of the arterial segment by the PTT.
