Abstract: A data collector agent (DCA) connector component running on a cloud computing network signals to a device interfacing platform component that a work request is ready. The device interfacing platform component runs on the cloud computing network and interfaces a device located outside the cloud computing network to the cloud computing network. The work request is for the DCA connector component to perform in conjunction with the device. The DCA connector component establishes a communication session with the device via the device interfacing platform component as initiated by the device. The DCA connector component performs the work request in conjunction with the device by tunneling to the device through the established communication session.

Abstract: Systems and methods for reducing erroneous weighing of items such as by detecting items extending beyond a periphery of a weigh platter whereby in one configuration, the system employs a light source disposed in or on a housing of a scanner-scale for producing a light beam along an edge of the weigh platter, the light beam being modulated to contain a defined packet of data; a detector for receiving the data-modulated light beam, the detector being disposed in or on the housing; and a processor coupled with the detector for decoding the defined packet of data responsive to the detector receiving the data-modulated light beam. Various indicators for alerting the operator of off-scale detection are also described.

The device preferably includes a holder for the probe; a handle to apply force directly or indirectly to the probe; magnets that assist with alignment of the holder and the handle during a process of inserting the probe into the filtering facepiece; and a spring that facilitates separation of the holder and the handle after insertion of the probe into the filtering facepiece. The holder may further include a puncturing device to facilitate insertion of the probe. The holder and the handle preferably are separate elements positioned opposite each other to apply force to the probe. In some aspects, the holder includes a piston for driving the probe into the filtering facepiece. The spring may surround the piston.
