An imaging apparatus includes a printhead carrier configured for movement along an X-axis. The printhead carrier includes a carrier housing having a first bearing pocket and a second bearing pocket. The first bearing pocket and the second bearing pocket are spaced apart along the X-axis. A Z-axis passes through a central region of the carrier housing. The Z-axis is substantially perpendicular to the X-axis. A first bearing is configured to be received in the first bearing pocket. The first bearing includes a first curved outer surface having a curve that extends in a direction of the X-axis. The curved outer surface is received in the first bearing pocket to facilitate a rotation of the first bearing in relation to the Z-axis of the carrier housing. A second bearing is configured to be received in the second bearing pocket.

A printhead capping assembly includes a cap holder and a printhead cap. The cap holder defines a cavity and a vent exit. The printhead cap has a base and a lip portion extending from the base. The lip portion defines an open interior region. The base is inserted into the cavity of the cap holder. The base includes a serpentine channel extending from the open interior region to the vent exit of the cap holder.

A backup roller is formed by a member having a rotational axis and a circumferential region around which a plurality of teeth are arranged. Each tooth of the plurality of teeth has a tip end extending in a direction away from the rotational axis. When the backup roller is rotated the tip end of each of the plurality of teeth sequentially extends toward the rotational axis of a drive roller at an angle non-orthogonal to the rotational axis of the drive roller.

The present invention provides optimized enveloping for a public key cryptography system. A sender may reuse a secret key in multiple communications to a recipient without the need to recompute or re-encrypt the secret key. The first time a message is sent to a recipient, the sender generates and encrypts a secret key, then stores the secret key, the encrypted secret key, and associated counter data in a local data store. For subsequent messages to the recipient, the sender determines from the counter data whether the secret key may be reused; if the secret key is reused, the sender updates the counter data. A recipient stores previously received secret keys in a local data store in both encrypted and decrypted form. If an encrypted secret key in a received message matches an entry in the local data store, the recipient uses the previously decrypted secret key to decrypt the message.

A method and apparatus for identifying and resolving conflicting data records are disclosed. The individual data fields of a master record are compared with the corresponding data fields of each source record in a particular data set. For each, one of various matching algorithms is used to assign a field matching score indicating the extent to which the data in the two data fields matches. The particular algorithm used to determine the extent of a match and to assign the corresponding score is dependent on the type of the data field. Once all of the data fields for a particular source record have been analyzed, the sum of the field matching scores is tallied to determine an overall record matching score for that particular source record.

A method and apparatus for backing-up and synchronizing mobile handset data are disclosed. According to one embodiment of the invention, a Mobile Solutions Platform (MSP) architecture and server are defined, such that the MSP provides back-up and synchronization servers to a wide variety of mobile handsets. In addition to supporting a wide variety of mobile handsets, the MSP architecture and server provide support for a wide variety of data types, to include contact information (e.g., names, addresses, and phone numbers), calendar information (e.g., meeting times, and appointment times), tasks, notes, as well as graphics and picture files, video files, and audio files (e.g., ringtones, and music files).
