Inventor: JACKSON BERNARD G
IPC: G06T1/60
Filed: 1997-12-19
Abstract: Interleaved data are converted to a planar format by an algorithm that follows map cycles throughout a frame buffer (12). Such map cycles result from iterating a function that maps planar addresses to CMYK addresses. There are three phases to the algorithm: in phase I (100), a 1-Cycle is processed and all of its member indices that are MAX_HIT in the array firstHIT¢! are saved. In phase II (100), all indices between 1 and MAX_HIT are visited, skipping any indices that have already been in a cycle. As each cycle is converted, any hits to indices between 1 and MAX_HIT are directly recorded in the array hit¢!, so that indices that have been used are quickly skipped. Phase III is skipped unless there are still some copies left to process. In phase III (120), there is no more space for recording every hit individually.

Abstract: A container (10) suitable for mounting on the neck of a bottle or other vessel having an annular abutment surface formed thereon and for containing a gift item consists of first and second wall sections (12,14) which are fixed together to form a generally closed space containing the gift item. One of the wall sections (14) has formed in it an opening (17) having around its periphery a plurality of elongate resilient fingers (18) projecting into the interior of the container. The fingers (18) together define a substantially frusto-conical structure such that when the neck of the bottle or other vessel is inserted into the container (10) through the opening (17) the fingers (18) are forced apart to allow passage of the neck until they have moved over the abutment surface formed on it. The ends of the plurality of fingers (18) engaged with the abutment surface to oppose movement of the neck of the bottle or other vessel out of the container. The container thus provides a secure means for securing a gift item to the neck of the bottle or other vessel as part of a promotional exercise.

Abstract: The invention at hand concerns containers for liquids (Fig. 1 ) such as drinking-glasses, drinking-cups or bottles which hold an integrated light source (Fig. 1/Nr.3),e.g. a LED, featuring capacitors (Fig.1/Nr.1) for the supply of electric potential for the light source. A wedge-shaped indentation in the container (Fig. 1/Nr.2) creates optimal dispersion of light. The use of capacitors as source of electric potential entails the following advantages over previous inventions.  There is no use of batteries or accumulators which have to be exchanged after a certain time of usage or storage (low environmental impact). Also, hours and hours of charging of an accumulator can be avoided.

Title: Structural core of the three-dimensional concrete reinforcing mat and method of its fabrication
Inventor: CEROVSKY JAROMIL
IPC: E04C5/06
Filed: 1998-02-05
Abstract: The invention applies to the structural core of the three-dimensional concrete reinforcing mat consisting of distribution bars and load-bearing bars, where the distribution bars (1) of folded length equal to the width (W) of the mat, are throughout their length bent forming a meander consisting of a continuous row of incomplete equilateral trapezoids with slanted sides (h w), shorter bases (b) and imaginary longer bases (c). The equilateral trapezoids of the distribution bar (1) are laying in the same plane oriented alternately mutually opposite each other so, that slanted sides (h w) of each two opposing each other trapezoids are of the same length and are identical. The straight load-bearing bars (2) of the structural core's length, are attached to meandrically bent distribution bars (1) into each corner-bend on inner side of their trapezoids. The distribution bars (1) and load-bearing bars (2) form together structural mat-core's longitudinal ribs (R) of regularly by 180° alternating trapezoidal cross-sectional form. The mat based on this structural core is designated for its usage primarily as reinforcement of concrete structures and of miscellaneous precast concrete products used in construction of highrises, bridges and/or in underground structures of civil engineering, as well as for military purposes, security installations and/or temporary structures, where this structural mat's core due to its formed longitudinal load-bearing ribs (R) would serve mainly without its combination with concrete as a steel structure, that is as a finished product.

Title: Method for operating at least one fluorescent lamp, and electronic ballast therefor
Inventor: KRUMMEL PETER
IPC: H05B41/298
Filed: 2000-06-16
Abstract: An integrated control and regulating circuit (IC) controls, via a half-bridge circuit (V2, V3), a load circuit (4) having the at least one fluorescent lamp (FL) by means of a drive circuit (CCO, SEL, HSD, LSD) regulated in a high-frequency manner. In the control and regulating circuit, each time the lamp is started and/or when there is a disturbance, a timer (PST, IT, CT) is started, which thus defines a sequence predetermined periods of time (.DELTA.pt, .DELTA.it, .DELTA.st, .DELTA.ot), inter ails preheating period (.DELTA.pt) and ignition period (.DELTA.it). In a monitoring circuit (MON), the pulsed load current of the load circuit is cyclically monitored in comparison with reference levels (Mp, Mi, Mdo and Mo) which are respectively predetermined for the periods of time, in order to detect a normal state or a disturbance in the load circuit, to control the current regulation of the drive circuit (CCO, ISC, SEL, HSD, LSD) in the normal state, or to trigger an automatic disconnection of the electronic ballast in the event of a disturbance. During the ignition period (.DELTA.it), a current signal which is derived from the load current and is fed to the monitoring circuit (MON) has superposed on it an internally generated DC signal (DC) having a defined level. The value thereof is dimensioned in accordance with the types and/or circuits of the fluorescent lamp(s) which are used in the load circuit, with the result that the signal that is superposed in this way is adapted to the predetermined, fixed reference levels (e.g. Mp, Mi) of the monitoring circuit (MON) independently of the lamp selection in the load circuit.
