Abstract: Systems, methods, and devices are described herein for integrated circuit (IC) layout validation. A plurality of IC patterns are collected which include a first set of patterns capable of being manufactured and a second set of patterns incapable of being manufactured. A machine learning model is trained using the plurality of IC patterns. The machine learning model generates a prediction model for validating IC layouts. The prediction model receives data including a set of test patterns comprising scanning electron microscope (SEM) images of IC patterns. Design violations associated with an IC layout are determined based on the SEM images and the plurality of IC patterns. A summary of the design violations is provided for further characterization of the IC layout.

Abstract: A hemodialyzer includes a housing, a hollow fiber membrane, a first cap, a second cap and a hydrophilic material . The hollow fiber membrane is disposed in the housing. The first cap is disposed on a blood inlet end of the housing and the second cap is disposed on a blood outlet end of the housing, wherein the blood inlet end is opposite to the blood outlet end. The hydrophilic material is formed on an inner surface of at least one of the first cap and the second cap.

Abstract: A vibration wave output instrument and its use method are provided. The vibration wave output instrument has a base, a vibration device, a pressure device, and a position mechanism. The position mechanism brings both the vibration device and the pressure device to a target region. The pressure device pushes the vibration device to touch against the target region. The vibration device outputs vibration waves beneath the target region.

Abstract: A film holder for an advanced photo system. The film holder includes a transmission mechanism, a support mechanism, a rotating member and a resilient element. The support mechanism is connected to the transmission mechanism and has a sliding groove obliquely formed thereon. The rotating member is disposed in the support mechanism and has a first transmission shaft and a sliding portion engaged with and sliding in the sliding groove of the support mechanism. The resilient element is disposed on the support mechanism and connected to the sliding portion of the rotating member.

Abstract: An optical disk drive is disclosed. The optical disk drive for operating an optical disk which is bi-directionally transported along a center axis of the optical disk drive includes a shield, a tray and a holder. The tray is movably connected to the shield. The holder pivots on the tray to form a cantilever with a free end. A space is defined between the free end and the center axis, and the optical disk is clamped between the tray and the holder.

Abstract: Towel rack has a mounting bracket, a hanging rod assembly and a pivot pin. The mounting bracket has multiple limits defined on the mounting bracket. The hanging rod assembly is pivotally attached to the mounting bracket and is curved. When users use the towel rack, towels and clothes hangers will not touch the wall because of the curved hanging rod assembly. When the towel is not being used, the towel rack can be folded against the wall to decrease the total volume and easily stored.

Abstract: Towel rail in accordance with the present invention has a bracket, a support and a pin. The bracket has multiple mounds defined on the bracket. The support is pivotally attached to the bracket and is arcuate. When users use the towel rail in accordance with the present invention, towels and clothes hangers will not touch wall because of the arcuate support. When users do not use the towel rail, they can fold the towel rail near a wall to decrease the total volume and easily stored.

Abstract: A storage device for fixing business cards and a camera. The device includes a box for storing an object, a first fixing device connected to the box for fixing the object, and a second fixing device connected to the box, having a predetermined distance from the first fixing device, for fixing a camera. The box is a business card holder or a camera case.

Abstract: A device for cleaning vagina includes a housing, a spout is engaged with the housing for inserting into vagina and for guiding water into the vagina, a number of outflow passages are formed in the spout for allowing water to flow out of the vagina, and a valve is engaged in the housing for controlling water flowing through the housing and flowing into the spout, water may be injected into vagina for cleaning purposes and may flow out via the outflow passages.
