Abstract: A stentless support structure capable of being at least partly assembled in situ. The support structure comprises a braided tube that is very flexible and, when elongated, becomes very long and very small in diameter, thereby being capable of placement within a small diameter catheter. The support structure is preferably constructed of one or more thin strands of a super-elastic or shape memory material such as Nitinol. When released from the catheter, the support structure folds itself into a longitudinally compact configuration. The support structure thus gains significant strength as the number of folds increase. This radial strength obviates the need for a support stent. The support structure may include attachment points for a prosthetic valve.

Abstract: An antenna system is provided, including a first antenna, a second antenna, a ground plane, and a resonant isolator coupled to the first and second antennas. Each of the antennas is configured to be a capacitively-coupled compound loop antenna, and the resonant isolator is configured to provide isolation between the two antennas at resonance. The two antennas may be symmetrical or asymmetrical and include a first element that emits a magnetic field and a second element that generates an electrical field that is orthogonal to the magnetic field. The radiating element of the second element may be capacitively coupled to the remainder of the second element. The resonate isolator may be comprised of a single conductive element or two conductive elements that are capacitively coupled.

Abstract: A spectator tray that has a drink receptacle and a snack receptacle. The drink receptacle is sized to be positioned in an opening, such as in an arm member of a spectator seat. The snack receptacle extends outward from the drink receptacle in a cantilevered fashion. The spectator tray further includes a removable cover member adapted to cover the snack receptacle. The spectator tray is adapted to receive accessories such as noise makers, horns, and a pole for use when mounting the tray into the ground. The spectator tray may be used in conjunction with a mounting device that engages with an adjacent seat. The spectator tray can be formed from a plastic material injection molded to include advertising images on surfaces thereof.

Abstract: A method of authenticating a user so that the user can access a website without entering a unique user credential. A user accesses a target and is presented with an authentication code and an address, and the user sends a message containing the authentication code to that address. Alternatively, the user is pre-supplied with an address and is presented only with an authentication code when the user accesses the target. The user's identity is authenticated by comparing an aspect of the metadata of the message with known metadata aspects, and the user is authenticated by comparing the authentication key presented to the user with the one received in the message. Both the user and the user's identity are authenticated in a single step without requiring the user to input any unique user credential.

Abstract: A compound loop antenna (CPL) is described that includes a capacitively fed magnetic loop and/or a capacitively fed electric field radiator. Embodiments include single-band CPL antennas and multi-band CPL antennas. The CPL antennas have been reduced in physical size by capacitively feeding the loop and/or radiator. The embodiments include at least one e-field radiation element that is capacitively coupled or not capacitively coupled, at least one magnetic loop element that is capacitively coupled. A continuation of the magnetic loop may be continued with either a wire or a connection to a second layer.

Abstract: An expandable delivery tool for aiding the deployment of a prosthesis device within a patient. The delivery tool has a generally elongated shape with a selectively expandable distal end region that flares outward in diameter. Once advanced percutaneously within a patient's vessel, the delivery device can help locate a target area, assist in deploying a prosthesis at a desired position and further expand the prosthesis after deployment.

Abstract: An air seal assembly for an aircraft control surface comprises a bulb-type air seal, a mounting bracket and a fastener. The bulb-type air seal has a hollow bulb portion, a T-shaped mounting extension, and a first through hole extending through the T-shaped mounting extension. The mounting bracket has a T-shaped channel configured to slidingly receive the T-shaped mounting extension of the air seal and a second through hole. The fastener has a head at one end and an opposite exposed end sized for extending through the first through hole in the T-shaped mounting extension and through the second through hole in the mounting bracket. The exposed end is accessible to tighten the fastener against the bracket to keep the air seal in place within the T-shaped channel.

Abstract: An intravascular cuff acts as a lining between a native vessel and an intravascular prosthetic device. During deployment, the ends of the cuff curl back upon themselves and are capable of trapping native tissue, such as valve leaflet tissue, between the ends. The cuff creates a seal between the vessel and the prosthetic, thereby preventing leakage around the prosthetic. The cuff also traps any embolic material dislodged from the vessel during expansion of the prosthetic.

Abstract: Embodiments provide single-sided and multi-layered circular polarized, self-contained, compound loop antennas (circular polarized CPL). Embodiments of the CPL antennas produce circular polarized signals by using two electric field radiators physically oriented orthogonal to each other, and by ensuring that the two electric field radiators are positioned such that an electrical delay between the two electric field radiators results in the two electric field radiators emitting their respective electric fields out of phase. Ensuring the proper electrical delay between the two electric field radiators also maintains high efficiency of the antenna and it improves the axial ratio of the antenna.

Abstract: An optometry apparatus includes an eye chart presentation optical system that presents an optometric chart to an eye to be examined as a subjective eye chart for subjective measurement and a control unit that controls the eye chart presentation optical system to present the optometric chart. The control unit executes an instant presentation of the optometric chart by controlling the eye chart presentation optical system to finish presenting the optometric chart when an instant presentation time has elapsed after starting presenting the optometric chart.
