A toilet seat apparatus according to an embodiment is a toilet seat apparatus to be placed on an upper part of a toilet bowl, the toilet seat apparatus including: a toilet seat on which a user sits; a light emitting unit that emits light; and a light receiving unit that receives light; first memory that stores data received by the light receiving unit; and an arithmetic processing device that executes transfer of data received by the light receiving unit to the first memory, and analysis and deletion of data stored in the first memory, in which the arithmetic processing device transfers the data received by the light receiving unit to the first memory, and deletes the data temporarily stored in the first memory when the data has been analyzed to be data that is not data based on the reflected light from falling feces.

A stabilized toilet seat and toilet bowl that operates to prevent the toilet seat, when placed in a parallel orientation relative to the rim of a toilet bowl, from moving laterally or diagonally. The stabilized toilet seat and toilet bowl includes an interlocking system integral with both the toilet seat and the toilet bowl which automatically engages whenever the toilet seat is hinged into the parallel orientation without placing any restriction on the toilet seat's hinging movement into or out of the parallel orientation. A locking protrusion integral with the toilet seat and a locking slot integral with the toilet bowl may form the interlocking system.

A toilet seat mounting assembly that includes a hinge mount on an upper surface of a portion of a pedestal, the hinge mount having a body with a bore; an anchor underneath a lower surface of the portion; a fastener extending through the bore and operatively coupled to the anchor to clamp the portion between the hinge mount and the anchor; a hinge base having a mount supported by the upper surface, the mount having an outer wall, which defines an opening that receives the body, and a locking feature flexibly coupled to the outer wall; and a lock cap rotatably coupled to the mount and having a wall. The wall retains the locking feature into a locking engagement with the hinge mount in a locking position of the lock cap, and the mount is removable from the hinge mount in a non-locking position of the lock cap.

An adjustable toilet guard is disclosed. This is a different concept and it helps keep bathrooms clean and families happy. It is flexible and can be adjusted based on the height preferences of the user. This is the first of its kind and there is nothing like it out there. It will also have glow in the dark borders in the handle grips and top edge of the guard to help facilitate the use of the invention at nighttime or low light situations.

Disclosed are absolute isolated light path structure, and a seat ring and a toilet seat using the absolute isolated light path structure. The absolute isolated light path structure comprises a light blocking plate, and a light emitting device and a light receiving device separated by the light blocking plate, the light blocking plate is configured for blocking light propagation between the light emitting device and the light receiving device, thereby avoiding the interference from the light emitted by the light emitting device to the light receiving device.

A weak current signal acquisition circuit, and a seat (10) and a seat cover (100) having the circuit. The weak current signal acquisition circuit uses two signal acquisition units as front input electrodes of an amplification circuit, and uses an in-phase differential input mode, so that the ratio of amplitudes of a differential mode signal sent to a subsequent-stage operational amplifier to a common mode signal is improved, thereby achieving the purpose of improving the signal-to-noise ratio of a weak current signal extracted by a signal acquisition unit. When people use a seat cover (100) in which a weak current signal acquisition circuit is mounted, thighs are in contact with a signal acquisition unit provided on the seat (10), such that the weak current signal acquisition circuit can acquire a human body's electrocardiosignal more effectively.

A toilet splash guard collects errant urine from a male urinating in an upright position. The toilet splash guard attaches toward the rear of a toilet bowl between the toilet seat and the bowl. The toilet splash guard has a flat body with a back side, lateral sides, and a curved portion conforming to the curvature of a rear of a toilet bowl. The flat body includes a wall extending along a periphery of the flat body except for along the curved portion, defining a urine collecting portion therein. The urine collecting portion can be sloped to allow urine to flow to the toilet bowl.
