Abstract: Sensor data generated by a sensor of a computer numerically controlled machine can be compared with a forecast. The forecast can include expected sensor data for the sensor, over a course of an execution plan for making a cut with a movable laser cutting head. The sensor data can be generated during execution of the execution plan. During execution of the execution plan, the sensor data can be monitored and a deviation of from the forecast can be detected. It can be determined, based on the detecting, that an anomalous condition of the computer numerically controlled machine has occurred. Based on the determining, an action can be performed.

Abstract: A moveable head of a computer numerically controlled machine may deliver electromagnetic energy sufficient to cause a first change in a material at least partially contained within an interior space of the CNC machine. A feature of the material may be imaged using at least one camera present inside the interior space to update a position of the material, and the moveable head may be aligned to deliver electromagnetic energy sufficient to cause a second change in the material such that the second change is positioned on the material consistent with the first change and with an intended final appearance of the material. Methods, systems, and article of manufacture are described.

Abstract: A computer numerically controlled machine may include a movable head configured to deliver electromagnetic energy to a part of a working area in which the movable head may be commanded to cause delivery of the electromagnetic energy. The interior space may be defined by a housing and may include an openable barrier that attenuates transmission of light between the interior space and an exterior of the computer numerically controlled machine when the openable barrier is in a closed position. The computer numerically controlled machine may include an interlock that prevents emission of the electromagnetic energy when detecting that the openable barrier is not in the closed position. The commanding may result in the computer numerically controlled machine executing operations of a motion plan for causing movement of the movable head to deliver the electromagnetic energy to effect a change in a material at least partially contained within the interior space.

Abstract: An execution plan segment of an execution plan can be received at a control unit of a computer numerically controlled machine from a general purpose computer. The execution plan segment can define operations for causing movement of a moveable head of the computer numerically controlled machine to deliver electromagnetic energy to effect a change in a material within an interior space of the computer numerically controlled machine. The execution plan segment can include a predefined safe pausing point from which the execution plan can be restarted while minimizing a difference in appearance of a finished work-product relative to if a pause and restart are not necessary. Operations of the computer numerically controlled machine can be commenced only after determining that the execution plan segment has been received up to and including the predefined safe pausing point by the computer numerically controlled machine.

Abstract: Methods and apparatuses for modulating a position error signal detection gate signal responsive to a track crossing velocity are discussed. The position error signal can be used to detect position information. A track crossing velocity can be estimated and then used via the modulating. Phase errors due to the track crossing velocity can be minimized.

Abstract: A circuit may be configured to reduce the amount of space used on a storage device when a transducer having a reader and writer passes from a writable data field to a read-only field by enabling both the reader and writer simultaneously. The circuit can be configured to reduce to a threshold level the noise on a read signal that can occur when the reader is over a read-only field and the writer is over a writable data field, and can ignore the read data when both the writer and reader are enabled simultaneously over a writable data field.

Abstract: Systems and methods are disclosed for writable servo zone overlap regions on a disc memory. An apparatus may comprise a controller configured to determine a servo gate (sgate) timing for an overlap zone including servo patterns of a first servo super zone and a second servo super zone of a disc memory, the sgate timing based on servo pattern timing for the first servo super zone and the second servo super zone. The controller may initiate writing to the overlap zone based on the sgate timing. The controller may also reduce the impact of servo pattern frequency change between zones by calculating a trajectory error prior to the crossing, and providing 1/X of the trajectory error into a servo feedback loop for a following X servo sampling points.
