Abstract: A printing system for printing images onto copy sheets and tab stock includes a media registration transport for transporting a media sheet along a path. The printing system further includes a sensing system having a plurality of sensors positioned in line and orthogonal to the feed direction of the sheet path for detecting a leading edge of the media sheet. A control system provides for detecting signals at the times when each of the plurality of sensors are occluded and a control algorithm compares every one of the sensor signals with each other of the sensor signals. The system then identifies at least one pair of sensor signals having inconsistent readings with the other of sensor signals and, determines the presence of a tab on the leading edge based on the inconsistent sensor signal readings and calculates sheet skew based on the other sensor signals.

Abstract: A CMOS structure is disclosed in which both type of FET devices have gate insulators containing high-k dielectrics, and gates containing metals. The threshold of the two type of devices are adjusted in separate manners. One type of device has its threshold set by exposing the high-k dielectric to oxygen. During the oxygen exposure the other type of device is covered by a stressing dielectric layer, which layer also prevents oxygen penetration to its high-k gate dielectric. The high performance of the CMOS structure is further enhanced by adjusting the effective workfunctions of the gates to near band-edge values both NFET and PFET devices.

Abstract: FET device structures are disclosed with the PFET and NFET devices having high-k dielectric gate insulators, metal containing gates, and threshold adjusting cap layers. The NFET gate stack and the PFET gate stack each has a portion which is identical in the NFET device and in the PFET device. This identical portion contains at least a gate metal layer and a cap layer. Due to the identical portion, device fabrication is simplified, requiring a reduced number of masks. Furthermore, as a consequence of using a single layer of metal for the gates of both type of devices, the terminal electrodes of NFETs and PFETs can be butted with each other in direct physical contact. Device thresholds are further adjusted by oxygen exposure of the high-k dielectric. Threshold values are aimed for low power consumption device operation.

Abstract: FET device structures are disclosed with the PFET and NFET devices having high-k dielectric gate insulators and metal containing gates. The metal layers of the gates in both the NFET and PFET devices have been fabricated from a single common metal layer. Due to the single common metal, device fabrication is simplified, requiring a reduced number of masks. Also, as a further consequence of using a single layer of metal for the gates of both type of devices, the terminal electrodes of NFETs and PFETs can be butted to each other in direct physical contact. Device thresholds are adjusted by the choice of the common metal material and oxygen exposure of the high-k dielectric. Threshold values are aimed for low power consumption device operation.

Abstract: Systems and methods for positioning a sheet in a feed path including at least one sheet drive roller driven in a rotational direction by a drive shaft in which the drive shaft translates in a lengthwise direction along the axis of the drive shaft. A power shaft rotates about the same axis as the drive shaft and is driven by a power source that is fixedly mounted in the system. The power shaft is fixed to the drive shaft by a flexible coupling that allows the drive shaft and the power shaft to move relative to one another in the lengthwise direction along the axis while maintaining corresponding rotational motion between the power shaft and the drive shaft.

Abstract: Parallel printing systems and methods incorporate inverter assemblies for not only inverting media during transport through the system but also to register the media or provide a velocity buffer transports with different drive velocities. The inverter assemblies can include the capability to optionally deskew the media and provide lateral registration corrections. The inverter assembly nip rollers are sufficiently spaced from process drive nip rollers to decouple a document in the inverter assembly from the highway paths. The method comprises combining the inverting function selectively with either the registering or the velocity buffering functions.

Abstract: A lead edge and/or trail edge sheet curl sensing and constraint method and system. First and second light emitters and detector pairs are aligned such that the light beams from the first light emitter and second light emitter cross at the transport media sheet substrate path, which constitutes the path of a media sheet substrate with zero curl. A media sheet substrate with either positive or negative curl on the lead edge of the sheet substrate interrupts light beams from the first and second light emitters, as detected by first and second light detectors. A similar approach can be used to detect the trail edge curl. The time delay between the light beam interruptions is proportional to the sheet substrate curl, and the order of interruptions indicates whether the sheet substrate curl is positive or negative. A first pair and a second pair of substrate constraint rollers can also be provided in the paper path upstream and downstream of the sensing system.

Abstract: An integrated printing system is provided comprising a first image marking engine and a second image marking engine. The first and second image marking engines can be serially arranged with one another in a first operating mode. The first operating mode includes marking and passing of media to and from the first and second marking engines. A control system is provided for detecting a failure within one of the first and second image marking engines. A second operating mode is provided wherein the control system detects the failure and enables passing of the media through one of the first and second marking engines and marking of the media in another of the first and second marking engines when the failure is of a specified type.

Abstract: Methods and apparatus for billing communications services through the use of AIN functionality are described. Billing information is communicated to a service control point by placing one or two calls to a service subscriber to be billed for a service. The calls encounter a trigger set at a switch. In response to trigger activation the switch sends a message to the service control point. The message includes billing information placed into a billing data field of the call. The service control point extracts the billing information received in the message or messages from the switch and bills the called service subscriber based on the received billing information. In the single billing call embodiment the device initiating the billing call is responsible for determining the amount of time for which the service is to be billed, e.g., conference duration, in addition to other billing information.

Abstract: Methods and apparatus for implementing call forwarding services using AIN techniques and next event list messages are described. Methods of notifying a subscriber of a call forwarded using AIN techniques are also described. In accordance with one feature of the present invention, a subscriber is allowed to set the number of rings which are allowed to occur prior to a call being forwarded. The number of rings, e.g., the ring count, is stored as part of a customer's call processing record (CPR) which is used by a service control point (SCP) to implement the call forwarding service. The ring count information may be updated via the Internet or via a dial-up telephone connection. Call forwarding customers are provided with a distinctive ring, e.g., a ring shorter than an ordinary telephone ring, to notify them when a call is being forwarded. Distinctive rings may be used to distinguish between different forwarding services.

Abstract: Parallel printing systems include first and second adjacent electronic printers and at least one sheet bypass section extending around the second electronic printer to provide a sheet transporting path overlying the second electronic printer and bypassing the second electronic printer. The sheet bypass section includes an output for merging printed sheets from the first electronic printer with printed sheets printed by the second electronic printer. The output preferably comprises a intermediate transport section having a first input aligned with the output of the bypass section and a second input aligned with the output of the second electronic printer.

Abstract: Communications methods for allowing groups of individuals, such as family members, to contact one another when no one is available to answer calls to a primary, e.g., family, telephone number are described. Calls which go unanswered are connected to a telephony device capable of storing messages and initiating conference calls. If the calling party is determined to be a family member the telephony device accesses a table of contact information corresponding to the unanswered telephone number and offers the caller the opportunity to hear messages from other family members and/or initiate a conference call to one or more family members who have supplied a contact telephone number. Family members can access and update the table of messages and contact number information by telephone or the Internet. Table information can be accessed and updated remotely thereby providing a method of communicating with family members even when no one is at home.

Abstract: AIN based methods and apparatus for authenticating and authorizing people to register information corresponding to a telephone number, e.g., in an ENUM database, are described. The methods of the invention may be used to authenticate a party seeking to register telephone number related information with ENUM. A trigger is set on an ENUM registration line. Calls to the ENUM registration line activate the trigger causing LIDB information corresponding to the calling party number to be retrieved. The retrieved information, e.g., name, address and/or phone number is supplied to an ENUM registration service which returns a password to be used when updating or supplying ENUM registration information corresponding to the phone number from which the registration call is placed at some future time, e.g., via the Internet. Assigned ENUM passwords can be obtained when forgotten by placing a call to the registration service from the registered or associated phone number.

Abstract: Methods and apparatus for implementing communication services such as voice dialing services are described.
