Abstract: A method is disclosed to seamlessly migrating multi-container Docker Compose applications to a single container IoT Edge System greatly expands the number of applications and solutions available. The ability to run multi-container Docker Compose applications on single container per application IoT Edge Devices with no significant modifications to the application and without impacting the security of the IoT Edge Device and System is accomplished by having a special container, called Composer, that can run Docker Compose commands to start, stop, and manage compose applications. In the IoT Edge System, a special Composer Controller container is created, that uploads the compose application to Composer. Once uploaded, the Composer Controller container instructs Composer to run the compose application.

Abstract: A first replaceable unit is provided for use with a second replaceable unit in an electrophotographic image forming device. The first replaceable unit includes a latch movable between a latching position for latching the first replaceable unit to the second replaceable unit and an unlatching position for permitting the first replaceable unit to separate from the second replaceable unit. The latch is positioned to contact a latch catch on the second replaceable unit in order to prevent the first replaceable unit from separating from the second replaceable unit when the first replaceable unit is mated with the second replaceable unit and the latch is in the latching position. The latch includes a cam follower surface for contacting a camming surface on the second replaceable unit during mating of the first replaceable unit with the second replaceable unit to cause the latch to move toward the latching or unlatching position.

Abstract: Sound or video systems are used to deliver predetermined content to a customer audience. It is important to validate that the intended material is being received and understood by the targeted audience. Sound or video system service providers prove their value by providing feedback metrics that the system is working as expected. The present invention automates and enhances this process and makes the validation continuous for constant validation at a much lower cost. Enhancements creates metrics beyond a human's ability to discern the quality of the service. The also includes features that can automatically determine the cause and recommended solution if the system's performance is not as expected. The metrics are then aggregated for full system wide operation in a graphical and tabular analytic interface.

Abstract: A toner container for use in an image forming device according to one example embodiment includes a body having a reservoir for holding toner, a toner port on the body in fluid communication with the reservoir, and a shutter translatable along a first dimension between a closed position blocking the toner port and an open position unblocking the toner port. A lock is translatable along a second dimension orthogonal to the first dimension between a locked position blocking the shutter from moving from the closed position to the open position and an unlocked position unblocking the shutter permitting the shutter to move from the closed position to the open position.

Abstract: A sorter processes trading cards in an affordable, accurate, and easy-to-use manner. The sorter includes an input and output bin. A transport path moves cards between the bins and has two scan bars, one above and one below the path. The scan bars capture an image of a top and bottom surface of ones of the cards. A controller coordinates movement of the cards along the path and receives the image for processing. Users interact with the controller by way of an interface to influence the processing. The sorter also includes a coil to detect metal foil on the cards. Other embodiments are envisioned.

Abstract: A method of determining the authenticity of a replaceable toner cartridge in a printing device using an elliptic curve E defined over a finite field Fq, where q is an integer, the method comprising: the printing device generating a random integer j, where the random integer j is in the interval of one to the integer q; the printing device calculating a point T=j·S, where point S is a point on elliptic curve E(Fq); the printing device calculating a binary value k which is equal to the binary random integer j with a bitmask m applied thereto; the printing device sending point T and binary value k to the replaceable toner cartridge; and the replaceable toner cartridge iteratively calculating point U=n·S for different values of integer n, where for each iterative calculation integer n takes different values.

Abstract: Methods for updating an imaging device are described. The methods comprise: receiving, by the imaging device, update information from a memory of a supply item connected to the imaging device, the update information comprising an update value, and updating a firmware variable of the imaging device based on the update information. An imaging device is also described. The imaging devices comprise firmware and a memory, the memory storing a firmware variable, wherein the firmware is configured to read the firmware variable, and the imaging device is configured to update the firmware variable, by: receiving update information from a memory of a supply item connected to the imaging device, the update information comprising an update value, and updating the firmware variable of the imaging device based on the update information.

Abstract: An assembly for an image forming device according to one example embodiment includes a toner container removably installable in the image forming device and a latch movable between a latching position restraining the toner container along a longitudinal dimension of the toner container and an unlatching position freeing the toner container to move along the longitudinal dimension of the toner container. A latch actuator has a user engagement surface that is movable along the longitudinal dimension of the toner container between a home position and an actuating position. Pushing the user engagement surface moves the latch actuator from the home position toward the actuating position causing the latch actuator to move the latch from the latching position to the unlatching position to free the toner container for removal from the image forming device.

Abstract: An imaging device comprising a controller, a prover supply item and a verifier supply item, where the imaging device is configured to authenticate the prover supply item by: sending a challenge response from the prover supply item to the verifier supply item, and determining a status of the challenge response. When the verifier supply item determines that the received challenge response is a correct output of an algorithm when challenge data is input to the algorithm, the status is determined as verified. A supply item configured to be operable as a prover supply item when installed in an imaging device. The prover supply item is configured to receive an indication of an algorithm to be performed and receive challenge data, perform the algorithm using the challenge data as input to determine a challenge response, and send the challenge response to a verifier supply item.

Abstract: A replaceable unit for an electrophotographic image forming device includes a housing having a reservoir for holding toner. An electrical connector is positioned on a first side of the housing. The electrical connector includes an electrical contact for contacting a corresponding electrical contact in the image forming device. The electrical contact of the replaceable unit is electrically connected to processing circuitry mounted on the housing. The electrical connector is movable between a first position and a second position. The electrical contact of the replaceable unit moves outward from the first side of the housing along a side-to-side dimension of the housing when the electrical connector moves from the first position to the second position. The electrical contact of the replaceable unit faces downward when the electrical connector is in the second position permitting the corresponding electrical contact to contact the electrical contact of the replaceable unit from below.
