Abstract: A foldable transport cart for planar materials for transporting planar materials includes material support frame pivotably coupled to a central frame, wherein the material support frame is configured to lock into each of a plurality of orientations including a vertical orientation and a horizontal orientation. The material support frame has a support surface configured to support a planar material when the material support frame is in the horizontal position and a pair of stop plates configured to support the planar material when the material support frame is in the vertical position. Each of a pair of caster frames is pivotably coupled to the bottom of the central frame and are moveable between a deployed position and a folded position. A collapsed configuration which facilitates storage results when the material support frame is vertically oriented and each of the pair of caster frames is in its folded position.

Abstract: An approach is provided for selecting one or more trust factors from trust factors included in a trust index repository. Thresholds are identified corresponding to one or more of the selected trust factors. Actions are identified to perform when the selected trust factors reach the corresponding threshold values. The identified thresholds, identified actions, and selected trust factors are stored in a data store. The selected trust factors are monitored by comparing one or more trust metadata scores with the stored identified thresholds. The stored identified actions that correspond to the selected trust factors are performed when one or more of the trust metadata scores reach the identified thresholds. At least one of the actions includes an event notification that is provided to a trust data consumer.

Abstract: An approach is provided for selecting a trust factor from trust factors that are included in a trust index repository. A trust metaphor is associated with the selected trust factor. The trust metaphor includes various context values. Range values are received and the trust metaphor, context values, and range values are associated with the selected trust factor. A request is received from a data consumer, the request corresponding to a trust factor metadata score that is associated with the selected trust factor. The trust factor metadata score is retrieved and matched with the range values. The matching results in one of the context values being selected based on the retrieved trust factor metadata score. The selected context value is then provided to the data consumer.

Abstract: An approach is provided in which facts are received and then one or more atomic fact trust analyses are performed on the facts. The atomic fact trust analyses result in various atomic trust factor scores. Composite trust analysis is performed using the atomic trust factor scores. The composite trust analyses result in composite trust factor scores. The atomic trust factor scores and the composite trust factor scores are stored in a trust index repository that is managed by a trust index framework. A request is then received for trusted data, the request being from an information consumer. The trust index framework then retrieves one of the composite trust factor scores from the trust index repository, with the retrieved composite trust factor score corresponding to the trusted data request, and this the retrieved composite trust factor score is provided to the information consumer.

Abstract: The present invention provides methods and systems for discovering and determining algebraic relationships between sets of data, such as numeric columns in a relational database, based on a “bottom-up” (or data-driven) approach. Embodiments of the present invention provide for the discovery and determination of algebraic relationships within a single relation or algebraic relationships across multiple tables that can be joined via a foreign key relationship. The foreign key relation can be one-to-one, many-to-one, or one-to-many. In order to discover algebraic relations, mean, variance and correlations calculations between columns are performed, for example, based on taking samples of the columns. Irreducible relations are then determined. Samples are taken from the irreducible relations and algebraic relationships between columns are determined based on various calculation techniques and correlations between the columns.

Abstract: A conveyor belt (1) is composed of a number of identical links in the formation of an endless belt, where each link comprises at least one axle (3) arranged transversely in relation to the direction of travel (2), and an outer link (4) at each side in engagement with the axle. Each outer link comprises an elongated hole for the adjacent link's axle, so that the belt can be driven in a curve in the plane of the belt. Each outer link has at least one securing hole for a transverse axle, where the coupling-together between the axle (3 and the outer link (4) is effected by a separable snap-lock. The outer link is moulded as a one-piece unit in a suitable plastic material, preferably by injection moulding. The outer links (4) can also be configured in a larger version for the construction of conveyor belts for operation in self-stacking helical systems.

Abstract: The disclosure is directed to an apparatus and method for receiving and processing an optical signal representative of electronic information. In an embodiment of the invention there is provided a light-emitting diode which is reverse biased to receive the optical signal and convert the optical signal to an electronic signal. Means are provided for determining time periods during which the electronic signal produced by the light-emitting diode is below a predetermined threshold. Means are provided for generating a dark current error signal indicative of a sampled output of the light-emitting diode during said time periods. Means are also provided for holding the error signal during other time periods when the electronic signal produced by the light-emitting diode is not below the predetermined threshold. Finally, means are provided for modifying the electronic signal produced by the light-emitting diode as a function of the held error signal to obtain an output electronic signal.

Abstract: The invention utilizes a commercially available so-called "quad-pack" of logic gates; i.e. four exclusive OR or exclusive NOR gates mounted in a package. With minimal use of additional components and minimal circuit coupling, a quad-pack of this type is used to produce a detector circuit with FM limiting and an approximate 90.degree. phase shift. The circuit can be used for detecting an FM modulated video signal.

Abstract: A decoder apparatus (200) provides an R,G,B,I video drive signal in a TTL type of format from a received composite video input signal which comprises sync information and displayable information, such as conventional black and white video or a digitally encoded color video signal comprising a sixteen level code for providing sixteen possible color combinations of R,G,B, and I, without loss of bandwidth. The decoder (200) includes means for receiving the composite video input signal (202,10) and restoring it into separate DC restored sync (20a, 20b) and black and white or color video display information (30, 40, 50), both of which may be displayed on the same RGB monitor (107). White reference level signals are dynamically provided from the sampled video information and are used by a flash converter (100) in converting grey scale digitally encoded color video information into the TTL format R,G,B,I type of video signal (60, 70, 80a, 80b, 82a, 82b, 82c) which recovers the origianl R,G,B,I color signal.
