Abstract: A method includes supporting, by a support, a bag containing one or more items of an order and detecting, by a sensor coupled to an end of the support, a weight of the bag and the one or more items when the bag is suspended on the support such that the weight of the bag and the one or more items is exerted on the support. The method also includes comparing, by a hardware processor, the detected weight to an expected weight of the order and communicating, by the hardware processor, an alert when the expected weight is unequal to the detected weight.

Abstract: Networked devices in a communications network share a common firmware key. Using the common firmware key, one networked device can encrypt configuration data it uses to operate in the network for distribution to other networked devices of the same or similar type. The networked devices that receive the encrypted configuration data then use the common firmware key to decrypt the encrypted configuration data, and using the decrypted configuration data, self-configure to operate on the network. This allows for the secure distribution of configuration data, as well as the self-configuration of networked devices without exposing the sensitive data needed for such configuration to a human.

Abstract: Systems and methods of controlling a point of sale (POS) device are provided. In one exemplary embodiment, a method comprises, by a first network node that is operationally coupled to a POS device over a one-to-one connection, with the POS device being operable to receive commands related to secured and unsecured functions of the POS device that are sent to the first network node over the network and then conditionally sent by the first network node to the POS device over the one-to-one connection, receiving, from the second network node, an indication that includes both a command related to the POS device and a network node identifier associated with the second network node so that the first network node is enabled to authorize the second network node to send the command to the POS device based on the network node identifier and an authorized network node identifier.

Abstract: Printers and printer systems for printing images on paper in different configurations and for dispensing printed paper in different directions are disclosed herein. According to an aspect, a printer includes a body defining openings. A printing unit is positioned within the body and can receive an instruction for printing an image. In a first print mode, the printing unit can print the image on the paper in a first configuration and dispense the paper in a first direction through one of the openings of the body. In the second print mode, the printing unit can print the image on the paper in a second configuration and dispense the paper in a second direction through another of the openings of the body. A sensing component can determine whether the printer is in the first print mode or the second print mode.

Abstract: Ophthalmic instruments, systems and methods enable tonometry and pachymetry measurements to be conducted simultaneously. As such, a patient's intraocular pressure (IOP) corrected for corneal thickness may be determined accurately by a single corneal applanation. Preferably, the ophthalmic instruments have a reference surface at a distal end of the instrument, an applanation plate spaced from the reference surface, and a compliant mount for mounting the applanation plate for resilient displacements relative to the reference surface. The instrument most preferably has a housing such that the reference surface is located at a fixed position at one end of the housing, and the applanation plate is mounted to that one end of the housing in coaxial spaced alignment relative to the reference surface by means of the compliant mount.
