Abstract: An embodiment includes a method to increase the efficiency of security checkpoint operations. A security checkpoint kiosk serves as a Relying Party System (RPS). The RPS establishes a secure local connection between the RPS and a User Mobile-Identification-Credential Device (UMD). The RPS sends a user information request to the UMD, via the secure local connection, seeking release of user information associated with a Mobile Identification Credential (MIC). The RPS obtains authentication of the user information received in response to the user information request. The RPS retrieves user travel information based on the user information. The RPS determines that the user travel information matches the user information. When the user travel information matches the user information, the RPS approves the user to proceed past the security checkpoint kiosk.

Abstract: A squeegee assembly for wiping a surface comprises a front flexible blade having an outer surface, an inner surface and a floor engaging edge, a rear flexible blade having an outer surface, an inner surface and a wiping edge, a support upon which the front and rear flexible blades are mounted, a vacuumized chamber bounded by the front blade, rear blade, support, and the surface, and a suction tube coupled to the support and positioned between the front and rear flexible blades. The rear flexible blade includes at least one aperture extending between the outer surface and the inner surface and spaced from the wiping edge.

Abstract: A portable vacuum cleaning system includes a portable vacuum unit for cleaning debris. The vacuum unit is powered by a self-contained first electric power storage device and may be carried with a strap in backpack-fashion. The system also includes a cart defining a receptacle for receiving the vacuum unit. The vacuum unit may be used when supported by the cart or when carried by an operator. A second electric power storage device is supported by the cart and electrically connectable to the vacuum unit for charging the first electric power storage device when the vacuum unit is supported by the cart. Further, when disposed in the cart, the vacuum unit is disposed at an angle of about 45 degrees allowing for ease of movement of the cart.

Abstract: Apparatus, devices and methods of operating multiple high aspect ratio hydrodynamic horizontal ladder oriented vanes with pliable hinges and rotation limiting flexible webs attached between flexible support beams on swim fins. The fins can have a foot pocket. A pair of parallel support beams can be secured to the foot pocket and support a plurality of hydrofoil vanes in a resisted pivotal arrangement. Pivotal rotation of the vanes can be restricted by flexible membranes, between vanes and beams, to provide an optimum angle of attack for the during swimming. The fins can have at least one pivoting vane region connected to the fin with a flexible hinge member.

Abstract: A control handle assembly (200) includes a rigid handle (202) for grasping by the operator to steer a walk-behind mobile machine (10) and a control portion (220) moveable relative to the handle (202) to control a function of the machine (10). A flexible extension (238) extends between the handle (202) and the control portion (220) and over the separation defined thereby. The flexible extension (238) flexes when pushed or pulled by the operator's hands and particularly when the flexible extension is engaged with both the control portion (220) and the handle (202) and when the operator's hand extends into the separation therebetween.

Abstract: The invention relates to fusion proteins and bacteria encoding them. The fusion proteins include a ligand-binding domain interposed between the splicing domains of an intein. An auxotroph-relieving protein domain is fused to one of the splicing domains so that the auxotroph-relieving function of the domain is activated upon ligand binding. The fusion proteins can be expressed in bacterial cells and used as sensors of binding of compounds with the ligand-binding domain of proteins such as the human estrogen receptors or the human thyroid hormone receptor. The bacterially expressed fusion proteins can detect and report agonist and antagonist activity characteristic of the naturally-occurring hormone with the ability to modulate the function of the protein from which the ligand-binding domain of the fusion protein is derived.

Abstract: The present invention relates to compositions and methods relating to development of modified inteins comprising one or more topoisomerase recognition sequences and the corresponding topoisomerase proteins and/or one or more recombination sites and the corresponding recombination proteins systems for use in affinity-based protein expression systems.

Abstract: Leading and trailing cylindrical brushes (14) are moved in an operation direction to sweep and wet scrub a floor In differing aspects, the trailing cylindrical brush (14) is rotated at a greater rotational speed than the leading cylindrical brush (14) to enhance sweeping ability and preferably in the order of 1500 RPMs to enhance polishing. The brushes (14) include spiraled, equally circumferentially spaced rows (R) of a multiplicity of equally spaced tufts (54). The tufts (54) of an adjacent trailing row (R) are indexed laterally from a leading row (R) by an index distance (T) less than one half of the distance (I) of the tufts (54) in the rows (R).

The at least one drip barrier may include a base surrounding the shaft, and a concave sidewall portion extending vertically from the base toward the blade and curved laterally inward toward the shaft to define a water collection reservoir with the base for collecting water drippage from the blade along the shaft. The concave sidewall portion may have an arclength spanning greater than ninety degrees.
