A dynamic document template contains a set of queries. Each query may include a query scope. The query scope may refer to a content of a source document that is maintained in a document collection. A content rule is applied to monitor the template for a change. A notification event is triggered when a change to the document collection results in an invalid query scope in the template. A notification event may also be triggered when a change to the document collection results in valid query but the template needs to be refreshed. An additional notification event may be triggered if the template is modified so that the resulting template is either invalid or needs to be refreshed with different content from the collection.

A system and method of tracking location and orientation of power tools utilized in the assembly and maintenance of complex systems is disclosed. The system can facilitate collaboration between maintenance and alert maintenance personnel to complete complex system activities.

A web-based shared document repository includes recommender system functions to allow users of the repository to input reviews of documents contained in the repository and to read inputted reviews. The recommender system functions appear as a seamless integration in the document repository by loosely coupling the shared document repository to a web-based recommender system.

Method and apparatus for finishing a receiver sheet or similar substrate by providing a protective coating on the receiver sheet for the benefit of, for example, protecting an image resident thereon. Such coating is created by applying and fusing a mixture containing a transparent, abrasion-resistant toner resin, and optionally components such as a light-fast material, to the receiver sheet.

An apparatus for developing a latent image recorded on an imaging surface with toner, including: a developer housing including a reservoir for storing a supply of toner; a donor member for transporting toner on an outer surface of the donor member to a development zone; a purging system, adjacent to the donor member, for removing toner the donor member and the reservoir.

A method and apparatus for heating a charging unit to an appropriate temperature in a uniform manner is provided. In accordance with one example embodiment of the present invention, a heater for use in a charger includes a base. First and second contacts are disposed on the base. A heating element couples the first contact and the second contact. The heating element has an energy density that increases approximately exponentially from a first energy density at locations distal from the first and second heat sink locations to a relatively higher second energy density at locations proximal to the first and second heat sink locations. The heater, according to further embodiments of the present invention, is disposed on an opposite side of the substrate layer from the AC electrode layer, and underneath the charger.

A resonator for applying vibrational energy to a member, for example a photoreceptor belt or developer/donor member, includes an energy transmitting horn member having a platform portion and a horn portion, the horn portion including a contacting portion for contacting a surface of the member, and a piezoelectric material in association with the horn member for driving the horn member to vibrate, the piezoelectric material responsive to a voltage signal from a voltage source. The piezoelectric material is a composite of at least one piezoceramic material and at least one of a polymer or air, and has a 1-3 configuration. By the selection of a piezoceramic/polymer composite material having the specified configuration for use as the vibratory energy producing source, or transducer, of a resonator, improved piezoelectric material performance is achieved, particularly with respect to control and/or elimination of undesired transverse vibration, and manufacturing complexity is reduced.

A rotatable charging apparatus includes a length extending between a first end and a second end, with the rotatable charging apparatus centered about an axis parallel to the length. The rotatable charging apparatus outer periphery forms N apparatus positions. One charging device is fixed to each of N&minus;1 apparatus positions. The remaining (Nth) apparatus position is devoid of a charging device, thus forming an &ldquo;empty&rdquo; charging device position. A host printing machine selectively causes the rotatable charging apparatus to rotate about its axis thereby selectively position any of its N&minus;1 charging devices to face a proximately-located photosensitive element. When a problem exists with the current charging device, or when the total number of operating hours of the current charging device exceeds a fixed threshold, the printing machine causes the rotatable charging apparatus to rotate from its current charging device to position a new charging device facing the photosensitive element. Also, the printing machine causes the rotatable charging apparatus to rotate from its current charging device to the empty charging device position facing the photosensitive element when a power-down or hard-stop condition exists in the printing machine.
