A system for verifying a price associated with an item in a retail environment includes a price tag having an optical member that includes an optical characteristic that modifies an amount of optical energy that leaves the optical member relative to an amount of optical energy received by the optical member, and a price tag holder including an optical sensor having an emitter and a detector. The emitter is positioned to emit optical energy onto the optical member and the detector is positioned to receive optical energy leaving the optical member. A computing device in operable communication with the optical sensor is operative to determine whether the price tag is accurate based upon a comparison between the amount of optical energy received by the detector and the amount of optical energy emitted by the emitter.

System and method for price verification in a retail environment

A replaceable unit for an image forming apparatus according to one example embodiment includes a housing and at least one transmissive member positioned on an exterior of the housing. The at least one transmissive member is arranged to receive optical energy from the image forming apparatus and has a transmissivity for modifying an amount of the optical energy that leaves the at least one transmissive member relative to an amount of the optical energy received by the at least one transmissive member. The at least one transmissive member indicates information relating to a characteristic of the replaceable unit.

Systems for optical communication between an image forming device and a replaceable unit of the image forming device

A system for customizing settings of an electronic device includes a replaceable component having an optical member for receiving optical energy. The optical member has an optical characteristic for modifying an amount of the optical energy that leaves the optical member relative to an amount of the optical energy received by the optical member. A support is located on an outer casing of the electronic device and the replaceable component is mountable on the support. The system further includes an optical sensor including a detector positioned to receive the amount of the optical energy leaving the optical member when the replaceable component is mounted on the support. A controller determines one or more predetermined settings to be applied to the electronic device based at least upon the amount of the optical energy received by the detector.

Systems for configuring settings of an electronic device for customization thereof

An apparatus includes a housing having a reservoir for storing consumable material and an outlet for exiting the consumable material from the reservoir; a rotatable shaft disposed inside the reservoir and positioned along a length of the housing; and one or more magnetic members disposed within the housing and coupled to the shaft so as to rotate therewith. The one or more magnetic members generate a magnetic field and when rotating indicate information about the replaceable unit. The information is based upon the presence or absence of the one or more magnetic members relative to one or more predetermined locations for receiving a magnetic member within the housing.

System and method for magnetic communication between replaceable unit and imaging device

Methods and systems for tracking locations of a plurality of devices includes initializing a server with a site floor plan, receiving ranging information transmitted by one or more devices of the plurality of devices at the server, creating a multi-dimensional map of locations of the plurality of devices based on ranging information using a location engine, and calibrating the multi-dimensional map of locations to the site floor plan calibrated with geospatial coordinates. Upon movement of a device from a first to a second location, ranging information changes between devices and maps, relative locations and absolute locations are updated.

Systems and methods for location-aware imaging devices

A micro-miniature fluid ejecting device. The fluid ejecting device includes a semiconductor substrate having fluid ejectors formed on a surface of the substrate. A flexible circuit is fixedly attached to the semiconductor substrate. The flexible circuit has power contacts for providing power to the fluid ejectors. At least one drive circuit is connected to the fluid ejectors. The drive circuit is disposed on one of the semiconductor substrate and the flexible circuit. A fluid sequencer is connected to the drive circuit for selectively activating the fluid ejectors. The fluid sequencer is also disposed on one of the semiconductor substrate and the flexible circuit. The semiconductor substrate is attached to a housing. A fluid source is provided for supplying fluid to the semiconductor substrate for ejection by the fluid ejectors. The fluid ejecting device provides low cost construction for application specific miniature fluid jetting devices.
