Abstract: An information security system and method that provides electric power to an authorized user and denies electric power to an unauthorized user. An administrator requests access for a user, and a site controller generates a key/receptacle tuple for the use. The key/receptacle tuple is communicated to a site power source, which broadcasts the key/receptacle information to all secure receptacles in a facility, or other infrastructure. The key is also communicated to the user. The user plugs in a device into a secure receptacle and provides the key via a secure adapter between the device and the secure receptacle. If the key is valid, the users' device is supplied with electric power; otherwise, electric power is denied to the unauthorized user's device. The usage of the secure receptacles are logged and analyzed by the site controller and reports are communicated to the administrator.

Abstract: An airfoil comprising a main wing and a high-lift body. The high-lift body defines a concave recess. The airfoil further comprises a sealing device having two sealing elements arranged in the concave recess. The sealing elements are plate-shaped and abut sectionally on the high-lift body and have side faces extending perpendicularly to the common rotational axis. When the high-lift body is moved between a retracted position and a deployed position, the sealing elements rotate relative to the main wing and relative to each other, such that an overlap between the sealing elements is smaller when the high-lift body is in the deployed position than when the high-lift body is in the retracted position.

Abstract: A deployable and foldable shield with improved stability, when it is to protect the carrier against weapons and thrown objects, comprising an elongated base plate having attachment means for attaching the base plate along the forearm of a person, and a plurality of substantially triangular and at least substantially equal-sided shield plates, supported by the base plate, which have a top angle (?) smaller than 40° and are pivotally mounted at a triangle corner enclosing the top angle (?) to a pivot projecting from the base plate, said shield plates forming a stack supported by the base plate when the shield is folded and forming a deployed shield surface supported by the base plate when pivoted away from the base plate. In order to improve the stability of the shield, when it is to protect the carrier against weapons and thrown objects, the shield plates are arranged in two stacks with a respective pivot for mounting and pivoting of the shield plates.

Abstract: A collapsible colander includes a bowl portion and a base portion. The bowl portion is made from a plurality of triangular panels that are pivotally secured together around a central pivot, and slidably joined two adjacent panels by sliding fasteners. Mating fastener components secured to the end panels permit the bowl to be assembled into a bowl shape. The base is a continuous band that is positioned in a generally circular configuration underneath of the bowl to support the bowl when the colander is in use. When the colander is collapsed, the collapsed bowl fits within the substantially flattened base.

Abstract: The present invention relates to a device and a method for determining the quality of surface. An illuminating light source radiates light at a predetermined angle onto the measurement surface. An optical detecting device receives the light reflected from said measurement surface and converts same into an electrical measurement signal. A processor controls the measurement sequence and evaluates the measurement results, which are emitted via an output device. The illuminating light source comprises at least one light-emitting diode. The light emitted comprises at least blue, green and red spectral components in the visible range of the spectrum. A filter is provided in the path of radiation between the light source and the photosensor.

Abstract: A handle structure for a flexible fan includes two corresponding holding brackets and two corresponding handle members. The holding brackets are provided at their inner sides with a plurality of receiving means and stop means so as to firmly clamp a segment of a steel wire frame of the flexible fan between the receiving and the stop means. The handle members are separately pivotally connected at one end to two ends of the holding brackets and respectively define a space for receiving two sides of the twisted and folded flexible fan therein when the fan is not in use and the handle members are pushed apart to abut against the frame of the fan. The handle members are formed with curved recesses for a comfortable grip by a the user's fingers. When the handle members are pushed to abut one another and become perpendicular to the fan, the user may stably grip the handle members to wave the fan easily.

Abstract: A fan device comprising two flat leaves inseparably attached to a flat hollow handle that serves as an envelope wherein the folded leaves can be tucked away when not in use. The fan opens for use by telescoping the leaves out of the envelope/handle part way, unfolding them, and then inserting side tabs of the leaves into side slots on the envelope/handle. Top center notches on both leaves are then interlocked forming a rigid plane comprising the two leaves joined to each other and to the envelope/handle to become a unit that is sturdy enough to be used for fanning. The surface area of the fan may be imprinted with indicia, for viewing during fanning or as a display.
