Abstract: An optical sensor includes a detector having a printed circuit board (PCB) and an inductive loop. The printed circuit board (PCB) has a photodiode cathode pad with a photodiode. The inductive loop is arranged around at least part of the photodiode cathode pad, and configured to receive inductive loop inducing signaling, and provide inductive loop signaling around the at least part of the photodiode cathode pad to provide inductive on the PCB to reduce or substantially eliminate unwanted electrical interference in electrical photodiode signaling provided from the photodiode. The inductive loop includes a trace and at least one via. The trace has a route along a signal path from a transistor collector pin around an LED anode pad. The at least one via is placed between LED anode pads to route the trace on a top side of the PCB, and the trace is routed alongside, near and around the photodiode cathode pad back to the LED anode of the LED anode pad.

Abstract: A machine for wrapping items to produce packages includes default settings which provide appropriate parameters for wrapping packages based on a ubiquitous feature of the item such as tray size. In addition, one or more exceptions to the default settings are included such that items of a given value for the ubiquitous feature which require special or unusual handling parameters will be detected and handled according to these different parameters. These parameters including exceptions are readily transferable between multiple wrapping machines. An autocalibration feature allows for specific differences in the tolerances and settings of different wrapping machines.

Abstract: A package wrapping machine includes a wrapping station where film is to be manipulated during a packaging operation. A support is provided for holding rolled film, the support located to permit film to be drawn into the wrapping station. A sensor arrangement detects package size data that is used to set one or more wrap parameters.
