Abstract: A sheet processing apparatus and methods of utilizing the same. The sheet processing apparatus includes a punch mechanism disposed along a media path at a punch point at which a hole is to be punched through a punch location on a media sheet advancing along the media path. The punch mechanism includes a rotatable punch arm having a punch head, and a punch motor for rotating the punch arm. As the punch location on the advancing media sheet approaches the punch point, speed of the punch motor is controlled to adjust a rotational speed of the punch arm based on feedback signals associated with each of the punch motor and a media path motor used to advance the media sheet such that the punch head arrives at the punch point at substantially the same time as when the punch location on the media sheet arrives at the punch point.
Abstract translation: 片材处理装置及其利用方法。 片材处理设备包括冲压机构，该冲头机构沿着介质路径设置在打孔位置处，孔将通过沿着介质路径前进的介质片上的冲压位置进行冲孔。 冲头机构包括具有冲头的可旋转冲头臂和用于旋转冲压臂的冲头马达。 当前进介质片上的冲头位置接近冲压点时，控制冲头电机的速度以根据与每个冲头电机和用于推进冲头的介质路径马达相关联的反馈信号来调节冲压臂的转速 介质片，使得冲头在与介质片上的冲头位置到达冲头位置的基本相同的时间到达冲头。

Abstract: An imaging device has a drive gear assembly which operatively engages with a backup roll gear of a fuser assembly when the fuser assembly is inserted into the imaging device. Such engagement causes the drive gear assembly to rotate, and in turn rotates a drive motor coupled to the drive gear assembly. The drive motor includes Hall Effect sensors associated with a sensor arrangement that senses rotation of the motor. During rotation of the drive motor, sensor signals are transmitted to a controller of the imaging device, the controller counting rising and falling signal edges of the received sensor signals. Based on the number of rising and falling signal edges, a message is sent to a user of the imaging device whether or not the installation of the fuser assembly was successful.

IPC: H04L9/32
CPC classification number: H04L9/3278 , B41J2/17543 , B41J2/1755 , G03G15/0863 , G03G21/1875 , G03G2221/1823 , G09C1/00
Abstract: An elongate physical unclonable function (PUF) is disclosed. The PUF has a longitudinal axis and contains a plurality of small magnetic particles. A much larger magnet is positioned on the longitudinal axis to indicate a home position. A low-cost linear translation mechanism may be used to read the PUF by referencing position information to the home position. Other devices are disclosed.
