Publication number: 20190001717Abstract: A printer includes a conveyor that feeds objects from a stack of nested objects to the printer. The conveyor includes a member having protuberances that extend from the member to hold the lips of objects in the stack except for the object closest to the printheads in the printer. A spindle mounted to a member is moved to be within an orifice of the object closest to the printheads to engage that object and pull it from the stack. The spindle rotates to facilitate the printing of the object. After the object is printed, it is released from the spindle and gravity directs the printed object along a ramp to an opening in the printer for collection.Type: ApplicationFiled: September 11, 2018Publication date: January 3, 2019Inventors: Michael F. Leo, Wayne A. Buchar, Brendan C. Casey, Daniel J. McVeigh

Patent number: 9874815Abstract: A method for forming a structure for a radio frequency identification device includes dispensing a photosensitive compound onto a substrate. Subsequently, first portions of the photosensitive compound are exposed to a light pattern from a light source, while second portions of the photosensitive compound remain unexposed to the light source. Exposing the photosensitive compound to light reduces the photosensitive compound to a metal layer. The unexposed second portions of the photosensitive compound may be rinsed away to leave the metal layer. Processing may continue to form an RFID circuit from the metal layer, and a completed RFID transponder comprising the RFID circuit.Type: GrantFiled: May 13, 2016Date of Patent: January 23, 2018Assignee: XEROX CORPORATIONInventors: Wayne A. Buchar, George A. Gibson

Publication number: 20180001662Abstract: A printing system facilitates the printing of articles of manufacture. The system includes an array of printheads, a support member positioned to be parallel to a plane formed by the array of printheads, a member movably mounted to the support member, an actuator operatively connected to the movably mounted member, an object holder configured to mount to the movably mounted member, and a controller operatively connected to the plurality of printheads and the actuator. The controller is configured to operate the actuator to move the object holder past the array of printheads and to operate the plurality of printheads to eject marking material onto objects held by the object holder as the object holder passes the array of printheads. The support member and printhead array are oriented vertically to enable the printing system to be installed in a vertical cabinet that provides a small footprint in a non-production environment.Type: ApplicationFiled: September 14, 2017Publication date: January 4, 2018Inventors: Wayne A.

Publication number: 20170330066Abstract: A radio frequency identification (RFID) tag or transponder that outputs a first signal when a product or product package is sealed. During one particular use, unsealing the product or product package disables the RFID tag, such that no active second signal is output (i.e., the second signal is a passive second signal). In another particular use, unsealing the product or product package removes one or more resonators of a multiresonator such that the second signal is an active second signal that is different from the first signal. The RFID tag need not be visible to identify whether the product or product package is in a sealed state or an unsealed state.Type: ApplicationFiled: May 13, 2016Publication date: November 16, 2017Inventors: George A. GIBSON, Wayne A. BUCHAR, John P. DiVINCENZO, Brendan C. CASEY
