Abstract: A computer implemented method for performing extraction is provided in the present invention. First, a layout of a semiconductor circuit having a resistor is imported by using a computer wherein a device region is defined in the layout and the resistor is located within the device region. Next, the device region of the layout are extracted, and a compensation value of Rs (Rc) is obtained according to the extracting step. An adjustment process is performed according to Rc to obtained a refined R value.

Abstract: A method for post-OPC verification including of several steps is provided. First, a pre-OPC layout of an integrated circuit (IC) is received. Then, a first OPC procedure is performed to obtain a post-OPC layout of the IC. After that, a first extraction process is performed on the pre-OPC layout and a second extraction process is performed on the post-OPC layout to respectively obtain a first netlist and a second netlist by using a processor. Next, a verification process is performed by using the processor to determine whether an electrical network of the first netlist and an electrical network of the second netlist are identical. The verification process is then terminated if the electrical network of the first netlist and the electrical network of the second netlist are identical. An apparatus for post-OPC verification is also provided.

Abstract: A handy spur structure related to a continuation-in-part application of U.S. patent application Ser. No. 12/7261860 includes: a spur main body, which is a curved rigid body adapted to a configuration of a heel section of a rider's shoe/boot, the spur main body having at least one post outward protruding from a middle section of the spur main body; and a soft and elastic lining member disposed on a portion of an inner circumference of the spur main body that is closer to a lower edge thereof. Multiple recessed/raised anti-slip stripes are formed on a surface of the lining member. The junction face between the spur main body and the lining member is more approximately orthogonal to the direction of the action force when treading on a horse's belly, whereby the possibility of peeling of the lining member from the spur main body along the junction face is minimized.

Abstract: A roping practice apparatus for realistically simulating motion of the head of an animal to train a roper in roping skill. The roping practice apparatus includes: a steering unit drivable and rotatable by a power source; a transmission section rotatable in response to the rotation of the steering unit, the transmission section having a first end mounted on the steering unit and a second end; a universal actuator to which the second end of the transmission section is pivotally connected; and a driven section mounted on the universal actuator and rotatable in response to the rotation of the transmission section. A head model is connected with the driven section and drivable by the driven section to swing back and forth and left and right within a range of 360°.

Abstract: A handy spur structure including: a spur main body, which is a curved rigid body adapted to a configuration of a heel section of a rider's shoe/boot, the spur main body having two end sections each of which is formed with at least one strap slot, a strap being passable through the strap slots of the spur main body and fastened around an instep of the shoe/boot to secure the spur main body to the shoe/boot, the spur main body having at least one post outward protruding from a middle section of the spur main body; and a soft and elastic lining member disposed on an inner circumference of the spur main body. Multiple recessed/raised anti-slip stripes are formed on a surface of the lining member for keeping the spur structure from slipping on the shoe/boot and avoiding abrasion thereof.

Abstract: A bit (10) includes a mouthpiece (12) having two mouthpiece members (20). Each of the mouthpiece members has an end (20a,20b) which faces the other mouthpiece member, and the two ends are connected to one another by a joining arrangement comprising (26) one or more pivots and a stop system. The stop system limits the relative angular displacement of the mouthpiece members from a reference position towards the rear of a horse. In the reference position, the joining arrangement and the two ends of the mouthpiece members connected by the arrangement lie approximately along a straight line. The stop system prevents relative angular displacement of the mouthpiece members from the reference position towards the rear of the horse or limits the relative angular displacement in this direction to a minor fraction of the maximum possible relative angular displacement of the mouthpiece members from the reference position towards the front of the horse.
