  • Patent number: 9176707
    Abstract: A scalar multiplication unit references a t-bit sequence representing a random number k one bit at a time from the most significant bit, and upon each referencing, sets in a work variable R[0] a value obtained by doubling a specific point G on an elliptic curve set in a scalar multiplication variable R, and sets in a work variable R[1] a value obtained by adding the specific point G to the work variable R[0]. The scalar multiplication unit 122 sets the work variable R[0] in the scalar multiplication variable R if the value of the referenced bit is 0, and sets the work variable R[1] in the scalar multiplication variable R if the value of the referenced bit is 1. A scalar multiple point output unit 123 outputs as a scalar multiple point kG a value obtained by subtracting a constant value 2tG from the scalar multiplication variable R.

  • Publication number: 20150308358
    Abstract: A time point t0 represents a time point when a turbocharged engine is brought into a decelerating state, and an opening degree of a throttle valve is decreased. A time point t1 represents a time point when an opening command to an ABV is issued. When the ABV has an abnormality, and when a WGV is stuck open, a turbocharging pressure before the time point t0 shows a tendency to fall below a target turbocharging pressure, and a turbocharging pressure after the time point t1 reduces slowly to approach a predetermined pressure. When the WGV is stuck closed, a turbocharging pressure before the time point t0 shows a tendency to exceed the target turbocharging pressure, and the turbocharging pressure after the time point t1 reduces with vigor to approach the predetermined pressure.

  • Publication number: 20150305751
    Abstract: Tissue compression devices with deflecting pressure elements and methods of using the same are described herein. The tissue compression devices include a pressure element and a retention structure attached to the pressure element. The retention structure may be configured to retain the intermediate portion of the pressure element over selected tissue in a selected location on a patient (such as, e.g., over a radial artery access site). Movement of first and second end portions of the pressure element towards each other along an actuation axis causes the intermediate portion of the pressure element to deflect away from the actuation axis towards the selected tissue.
