  • Publication number: 20240119205
    Abstract: A computer-implemented method, system and computer program product for recommending design changes in designing a digital integrated circuit. An analysis of the digital integrated circuit being designed is performed, where the result of such an analysis involves violations being identified and stored. A stored violation, such as a cross-domain, cross-hierarchy and multi-cycle violation, may then be analyzed to identify a root cause of the violation using a rule. Such a rule may be used for triaging various failures in the cross-domain, cross-hierarchy and/or multi-cycle violation of the digital integrated circuit. A design change in the design of the digital integrated circuit may then be recommended based on the identified root cause of the violation. In this manner, the root cause of failures are effectively identified in the design of digital integrated circuits using an offline analysis of cross-domain, cross-hierarchy and/or multi-cycle violations using a rules-based approach.

  • Patent number: 8499681
    Abstract: A fluid displacement device, particularly for use of the device to pressurize balloon catheters, or the like. The device includes a plunger which is displaceable through a housing, and an actuating mechanism which engages the plunger. The actuating mechanism includes a nut member that is biased into engagement with a threaded portion of the plunger. The device has a press-to-release feature wherein the plunger is instantly releaseable by simply depressing a control surface to overcome a restorative spring force. Subsequently, the plunger can be translated using macro movements (i.e., by pushing or pulling the plunger).

  • Patent number: 8141699
    Abstract: An improved contact lens case which includes domes that are provided on hinged members. Preferably, the contact lens case is configured to efficiently utilize space and volume such that no more than 10 cc's of contact lens solution are required to disinfect contact lenses in the case. The hinged members are preferably non-planar which allows the domes to be provided on the hinged members, and allows the use of deep larger diameter, back-to-back cages on the stem, without having to resort to using more than 10 cc's of fluid to immerse contact lenses that are disposed on the domes, between each of the domes and a respective cage. Each of the hinged members has a cylindrically-curved shell form in which the axis of its curve is approximately parallel to the central axis of the central planar stem member.

  • Patent number: 7322999
    Abstract: A tissue punch which is configured to operate by utilizing a spring force to compress tissue between a rotatable cutter blade and a tissue piercing element. The tissue punch is configured such that once the spring force is applied, the cutter blade can be selectively rotated by the user. The rotation of the blade, assisted by the compression from the spring force, causes the cutter blade to cut through the tissue. Three different methods for creating an anastomosis for locating a bypass graft are disclosed. In each method, bypass graft material is installed on a tissue punch and then sutured. Depending on the method, the tissue is punched either before or after the suturing.

  • Patent number: 6938319
    Abstract: An actuating mechanism for rapidly and selectively moving a threaded screw and nut member combination into or out of threaded engagement, particularly for use to pressurize angioplasty balloon catheters, or the like. The mechanism includes a housing and a threaded screw structure slidably displaceable through the housing. A nut member having partial threads is selectively engageable and disengageable with the threaded screw structure. The mechanism includes a carrier member and is designed to be assembled from the rear. The carrier member is preferably configured to be retainably engaged with the housing via a bayonet arrangement, such as a quarter-turn bayonet arrangement, and is configured to provide an audible indication when it is, in fact, properly and fully installed. Preferably, the housing is configured to receive a pressure gauge directly into a threaded bore on the housing. An improved method of assembling an actuating mechanism is also provided.
