Abstract: A slip-in type sanitary cover is a plastic bag and includes a cut peripheral edge to define a plastic film that can be torn along the cut peripheral edge to form a hole. Extremely-small-area connecting points are provided on the cut peripheral edge of the plastic film. A larger-area connecting point is located on a front end of the cut peripheral edge of the plastic film. The plastic film is connected to the sanitary cover by the extremely-small-area connecting points and the larger-area connecting point. The plastic film includes at least one hot-melt pressing/bonding point that can hook a front end of the toilet seat when the toilet seat is slipped into the sanitary cover. The extremely-small-area connecting points are pulled and torn off to form the hole when the toilet seat is completely slipped into the sanitary cover. The larger-area connecting point is still connected to the plastic bag after the hole is formed.

Abstract: A portable self-attached sanitary cover for toilet seats is a flexible and annular pad and has an outer edge section, an inner edge section, a seat recess, a weighted section, an excreting hole and a folding gap. The seat recess is formed between the outer edge section and the inner edge section. The weighted section is mounted securely on the outer edge section. The excreting hole is formed through the portable self-attached sanitary cover and is surrounded by the inner edge section. The folding gap is formed in the portable self-attached sanitary cover. Because the portable self-attached sanitary cover has the weighted section, the outer edge section is capable of drooping to tightly abut an outer rim of a toilet seat. Accordingly, the portable self-attached sanitary cover is securely positioned on the toilet seat.

Abstract: A slip-in type sanitary cover for toilet seats is a bag and has a bag opening, two side edges, a closed side, a bag space and an excreting hole. The side edges are respectively located at two opposite sides of the slip-in type sanitary cover. The closed side is opposite to the bag opening. The bag space is formed in the slip-in type sanitary cover. The excreting hole is formed through a central section of the slip-in type sanitary cover. Because the sanitary cover is bag-shaped, the sanitary cover can easily enclose a toilet seat. As long as the user's butt sits on the sanitary cover, the sanitary cover is tightened. Accordingly, the sanitary cover is easily and securely positioned on the toilet seat.

Abstract: A device for a multi-boot system with network switches has a box, a selection module and a bridge connecting card. The box has an operation panel mounted with multiple switches. The selection module is mounted in the box and has a hard disk selector and a network selector. The hard disk selector has a power input port, multiple power output ports connected to the power input port via part of the switches. The network selector has a network input port and a network output port connected to the network input port via the other switches and is connected to a network cable. The bridge connecting card is mounted outside of the box. The multiple switches can form multiple combinations. Each combination corresponds to one operating system for booting and the communicating status with Internet.
