An automatic doorbell driver that utilizes the power, wiring, and primary load of a conventional doorbell system. The automatic doorbell driver comprising coupling means for coupling the automatic doorbell driver to the conventional doorbell system; power supply means for supplying power to the automatic doorbell driver; sensing means for sensing an object in a proximity zone; and switching means responsive to the sensing means for coupling power to, and thereby controlling the energization and de-energization of, the primary load of the conventional doorbell system; whereby the automatic doorbell driver can easily convert the conventional doorbell system into an automatic doorbell system.

A method embodiment herein has a central storage device periodically receiving images of documents. These documents have written or printed thereon financial information and can relate to a single tax entity. These images are supplied from at least one remote device over a network. The images are processed (at the central storage device) to classify the images according to tax classifications and to extract the financial information from the images. With this information, the financial information can also be classified into tax classifications. This method also accumulates, over a tax period (e.g., tax year), the images and the financial information in the tax classifications as the images are periodically received by the central storage device to create an accumulation of financial information and a corresponding accumulation of images. From this accumulation of financial information for the tax year, the method prepares tax reports and outputs the tax reports.

The present invention relates to a conveyor system and a method for merging or crossing of at least two conveyor lines (22, 24, 58) on which transport units (48, 50), particularly containers, are conveyed in an upstream direction (28), wherein the conveyor lines (22, 24) meet each other in an intersection point (26), wherein each of the conveyor lines (22, 24, 58) respectively comprises, upstream relative to the intersection point (26), one group (30, 34) of conveyor-line segments (32, 34), wherein the conveyor-line segments are respectively operable with a variable conveying velocity, the method comprising the following steps: conveying transport units (48, 50) towards the intersection point (26); detecting and determining a traffic density of the transport units (48, 50) on the conveyor lines (22, 24, 58), particularly at the conveyor-line segments (32-1, 34-1) which are located upstream; determining conveying velocities for the conveyor-line segments (32, 34) so that transport units (48, 50) which are conveyed on one of the conveyor lines (22, 24) do not collide at the intersection point (26) with other transport units (48, 50) which are conveyed on the other conveyor lines (24, 22), and without the need to stop the transport units (48, 50) in a region of the conveyor-line segments (32, 34); adapting the conveying velocities of the conveyor-line segments (32, 34) to the conveying velocities determined in this way, wherein the conveyor-line segments (32, 34) respectively can be operated at a different conveying velocity.

A system and a method is provided for fitting an aircraft cabin with modular sidewall panels, window reveals, and foam insulation blocks in an integrated manner. The system comprises a sidewall panel which may have one or more openings therethrough to receive a window reveal held by snap-fit fastenings. The bezel of the window reveal may be held by snap-fit fasteners for easy removal to allow removal and cleaning of the inner dust cover disassembly of the sidewall panel. Foam insulation blocks may be molded to fit in the cavity between the outer wall of the aircraft and the sidewall panels, held in place by compressive pressure between the frames of the airframe. The outer extent of the window reveal is tapered inwardly to guide the window reveal to mating contact with an outer window assembly in the aircraft fuselage without further adjustment of the sidewall panel.
