A method and system that allows an on-line shopper to be assigned a queue number for each department in a store is presented. Each time the shopper's number comes up in a queue in a specific store department, a real-time audio/video session is initiated between the shopper and a personal assistant who is physically located in that specific department. Thus, the shopper is able to seamlessly and instantly move from department to department with minimal waiting down-time.

A display system is disclosed. The display system includes a base, a screen movably coupled to the base, and a control unit coupled to the screen. The control unit adjusts the screen to a position based on at least one condition. The at least one condition can be an attribute such as a height or an eye position. According to the system and method disclosed herein, the display system increases the convenience of a user by automatically adjusting the screen to an optimal position for the user. As a result, improved readability of the screen is achieved while simplifying the use of the display system.

A document feeder device is disclosed. The document feeder device includes a frame, a first roller shaft coupled to the frame, and a second roller shaft coupled to the frame. The first shaft is cantilevered. The document feeder device further includes a bearing coupled to the first roller shaft. The bearing has an eccentric shape and the eccentric shape allows the bearing to be rotated such that the position of the first roller shaft stays parallel to a second roller shaft. As a result, rollers attached to the first and second roller shafts are kept aligned so that they reliably feed documents through a printer. The document feeder device decreases production costs by eliminating the need for additional frame hardware and/or more rigid frame hardware.

A document feeder device is disclosed. The document feeder device includes a frame and at least one cantilevered roller shaft for advancing a document, where an unsupported end of the at least one cantilevered roller shaft floats. The document feeder device eliminates the need for a rigid frame to support the unsupported end. This decreases the cost of production by eliminating the need for additional frame hardware and/or more rigid frame hardware. The document feeder device can be implemented in existing designs.

A receipt printer having a scissor cutter for cutting off a receipt from a paper roll. The scissor cutter includes a moving blade that articulates across an adjustable stationary blade. The adjustable stationary blade is adjustable laterally according to whether a full cut or a partial cut across the paper roll is desired. If a full cut is desired, the stationary blade is positioned against the full width of the paper roll. If a partial cut is desired, the stationary blade is positioned against only a portion of the width of the paper roll.

A sheet and web cleaner has a pair of substantially identical units in facing relation, providing a path for transporting a sheet or web therebetween. Each unit includes a suction hood with an inlet slot. A pair of channels adjacent and parallel thereto have a pressurized air ionizing bar which discharges ionized air at high velocity onto a moving sheet or web. A faceplate covers the channels and the inlet slot and has a tapered central elongate inlet opening which overlies the inlet slot. Elongate air discharge openings overly each of the channels adjacent the inlet opening. A plurality of spaced ridges are disposed on a side of the faceplate proximate the sheet or web oriented relative to a direction of travel of the sheet or web from a travel direction towards respective edges of the sheet or web. Spaces between the ridges communicate with the inlet and discharge openings.
