  • Publication number: 20220183461
    Abstract: A support system for mounting a shelf to cabinet walls having vertical slots therein. The support system comprises rack rails to insert in the slots, each one of the rack rails comprises a series of upwardly arched channels. The support system further comprises mounting components to mount to the rack rails at similar heights, each one of the mounting components comprising a support face for supporting the shelf, an arched arm to be inserted in the arched channel, and an abutting face to contact one of 1—the rack rails to be mounted thereto and 2—one of the cabinet walls to be mounted thereto through one of the rack rails thereby limiting course of the arched arm in the arched channel. Once the mounting components are mounted to the rack rails, the mounted components provide support faces to set down the shelf thereon.

  • Publication number: 20210100462
    Abstract: A system for assessing a vascular condition includes a pressure sensing catheter and a pressure guidewire. Heartbeats of the patient can be detected while the pressure sensing catheter and the pressure guidewire are positioned at the proximal position and at a distal position respectively. A diastolic pressure ratio zone (dPR zone) is located within a heartbeat from analysis of a signal from at least one of the pressure sensing catheter and the pressure guidewire. The dPR value can be obtained by calculating an average of several ratios of Pa to Pd taken over time within the heartbeat. A multi-beat metric (dPRc) is calculated that includes the dPR value and that also includes a high frequency sample whole heartbeat pressure ratio.

  • Patent number: 10349840
    Abstract: The present document describes a system for equalizing the pressure of a pressure guidewire against the pressure of an aortic pressure device: the system comprising two methods of equalizing the pressure against each other, one method that involves a gain adjustment and another method that involves the addition of an offset; the method further comprising a method for detecting which method should be applied to the situation, the detecting methods including: the contribution of the operator; an algorithm detecting the first equalization from subsequent post procedure equalizations, the algorithm including various factors such as incrementing the equalization requests, measuring the elapsed time and others.

  • Patent number: 9591932
    Abstract: A bracket and standard assembly comprises a standard having a plurality of spaced apart holes. A bracket comprises a support body having an elongated portion extending along a longitudinal axis. A connector end comprises at least one hook projecting rearwardly from the support body and passing through a hole in the standard to releasably hook the bracket to the standard, the at least one hook comprising a downwardly projecting tooth, the at least one hook defining with the support body a receptacle, a portion of the receptacle being delimited by a forwardly oriented contact edge of the tooth, the receptacle receiving one of wall portions of the standard. A finger projects generally upwardly from the at least one hook and having a forwardly oriented contact edge, the forwardly oriented contact edge of the finger being rearward of the forwardly oriented contact edge of the corresponding tooth along the longitudinal axis.

  • Patent number: 4716850
    Abstract: The floatation assembly includes a pair of inverted U-shaped rails, the legs of which are adapted to be secured to the front and to the rear of the vehicle frame, with the bight portion of the rails extending substantially horizontally over a vehicle driver seated in the off-road vehicle. A front and a rear buoyant member is connected to the rails and shiftable between an operative and inoperative position. In their operative position, the two buoyant members extend forwardly and rearwardly of the vehicle in alignment therewith to render the same water-borne. In the inoperative position, the front buoyant member rests in inverted position on the bight portion of the rails, while the rear buoyant member is folded upwardly against the rear legs of the rails. When in operative position, the two buoyant members can be vertically adjusted with respect to the vehicle, in cordance with the weight of the vehicle itself and of its load.
