Low-profile service stations for use with printers are described herein. One example service station includes a shuttle to support a cap sled. The shuttle has a shuttle drive and a pump drive positioned such that at least one of the shuttle drive and the pump drive does not extend between a first side and a second side of the shuttle. The shuttle drive is coupled to a printer drive to move the shuttle between a first position and a second position.

A method and system for providing distributed network access point installation and management. A network provider installs and/or operates a plurality of access points at locations of a retail entity. Each access point may provide services such as Internet access, and/or content such as audio, video, text, and/or graphics, among other types of services. A carrier, such as a telephone or cable company, may compensate the network service provider for installation and operation of the access points. The carrier may in turn charge its subscribers for network access at the retail entity locations. A plurality of different carriers may provide compensation and allow respective subscriber access. The network access points may be configured to allow each carrier to present a point of presence to its subscribers at the retail entity locations. The installed network may also provide service for retail entity back office functions.

A carrier bead pickoff device is provided for removing ferromagnetic carrier beads from a developed image-carrying surface of a moving photoreceptor in an electrostatographic image reproduction machine. The carrier bead pickoff device includes (a) an elongate stationary core having a first elongate segment, and a second elongate segment, the second elongate segment including a primary magnetic member for generating a concentrated magnetic field within a pickoff region locatable proximate the developed image-carrying surface; (b) a rotatable, non-ferromagnetic cylindrical shell mounted co-axially over the elongate stationary core and having a first end, a second end, and a shell wall having a smooth outer surface; and (c) at least one elongate ferromagnetic strip formed over a portion of the smooth outer surface (i) for rotation with the portion, (ii) for temporary magnetization when rotating through the concentrated magnetic field within the pickoff region, and (iii) for contacting and retaining ferromagnetic carrier beads, attracted by the primary magnetic member towards the smooth outer surface, during rotation of the portion of the smooth outer surface through the pickoff region.

A pneumatic motor trigger actuator includes a trigger housing adapted to engage a pneumatic motor trigger of a pneumatic tool. A top plate is coupled to the trigger housing. A primary valve is coupled to the top plate and has an open configuration and a closed configuration. The primary valve is pneumatically coupled to the trigger housing such that air flow through the primary valve, when the primary valve is in the open configuration, enters the trigger housing and causes a plug to physically engage the motor trigger with sufficient force to move it to is fully engaged position. The primary valve includes a primary switch and an automatic stop switch. The primary switch is engagable by an operator to configure the primary valve in the open configuration. The automatic switch is engagable by an object to move the primary valve to the closed configuration when a predetermined condition is met.

A package (20) of articles comprises a bottom panel (24), and a top panel (26). The top panel is operatively positioned and joined with the bottom panel (24) to provide a closed package. The top panel (26) is appointed to face toward a user, and a plurality of personal care articles (22) are contained in the package (20). The package (20) includes an opening mechanism (34) which provides access to the articles (22), and each article includes a liquid-permeable topsheet layer (36), and a backsheet layer (38). A data layer (42) is operatively joined to the article (22), and is intended to be selectively repositioned prior to using the article, to enable full functionality of the article. Data indicia (44) are located on the data layer (42) and configured to communicate a message to the user. The message can be related to at least one of motivating the user, entertaining the user, educating the user, and inspiring the user. Each article (22) is positioned in the package (20) with its data layer (42) arranged to face toward the user when the article (22) is first presented to the user upon removal through the opening mechanism (34).
摘要:
A self-checkout system includes a first conveyor having a security tunnel which measures a characteristic of a product placed on the conveyor. A code identifying the product is first input into the system through UPC scanning or other input means, and then placed on the conveyor. When the characteristic of the product is measured (e.g., weight, height, width, length), it is compared to corresponding information within the system. If the data matches or is within a predetermined tolerance, the product is transported down the conveyor to a second conveyor, which further transports the product to a bagging area. When the customer is finished scanning products, an input device allows the customer to select self-payment through either cash, credit, debit, or other means (e.g., ebt, store credit and the like). Other features include automatic security tag deactivation and coupon redemption.
