Abstract:
A smart tag reading system is provided that has the ability to query sensor tags that have energy harvesting capability. In one embodiment, an adaptive reader system learns the state of each tag and how long the tag takes to charge. Tags that charge relatively quickly can be accessed more frequently. Others that do not charge as quickly, readings can be performed at much longer intervals allowing the tag a longer time to gather enough energy to complete the transaction. The reader query system can then adapt to the environment and state of the individual tags.
Abstract:
An imaging system having a solid-state auto focusing system advantageously images broadband light reflected from an object to be imaged using a lens objective having chromatic aberration, which focuses different colors of light at different focal planes. Using the color information in the focal planes in conjunction with an object distance determined by a range finder, a luminance plane is constructed that has a focused image of the object. The system provides the focused image of the object without the use of any moving parts.
Abstract:
System, method, article for determining registration and/or skew errors in a print medium with respect to a printing element includes a print medium including a two-dimensional pattern including a grid within a geometric shape. The grid has a plurality of vertical and horizontal lines, the intersection of each forming a cross-hair defining an X-Y positional data point; the collection of data points defining a data set. The geometric shape is in the form of a two-dimensional target having a plurality of concentric rings; an innermost one enclosing at least one of the X-Y positional data points in the data set. The printing element provides a marker onto the print medium. The positional location of the marker with respect to the one of the at least one enclosed X-Y positional data point defines a directional displacement vector for correcting registration and/or skew error between the print medium and the printing element.
Abstract:
A mobile computing device is disclosed for displaying backlight and diffuse reflecting information. The mobile computing device is configured to include a processor, a first LCD display unit connected to the processor, and a second diffuse reflecting display unit connected to the processor. The mobile computing device is further provided with a display panel interface, such as a mouse or a gravity detecting device like an accelerometer, configured to detect a property for activating a display type. The processor is configured to send information to be displayed to the first display unit or the second display unit or both depending on the display type property detected.
Abstract:
A system includes a terminal, a wireless access network, an IP telephony network, a core network gateway from the IP telephony network to the public mobile phone network and a network device, which connects the wireless access network to the IP telephony network and adapts the IP telephony network services to be used by utilizing the circuit-switched signaling protocols of the terminal. A location updating request is received from the terminal over the wireless access network. Location updating is performed via a core network gateway. The network device performs user registration to the IP telephony network using a domain name formed by the phone number of the user and the domain name of the network device or the numeric IP address as the address connection to be registered and as location data in the IP telephony network.
Abstract:
Automatic data collection devices such as barcode readers, RFID readers, magnetic stripe readers and the like may be tested using ADC device test executables, modules, or processes stored at a variety of network locations. One or more sets of tests or work lists may be defined to facilitate testing. Tests may be identified by name and/or keyword. Keywords may be indicative one or more functionalities tested by the respective ADC device test module.
Abstract:
An apparatus and method for selectively attaching sensor(s) or antenna(s) to a mobile device at a convenient location are provided. The mobile device includes a body and a processing unit housed within the body for running an application, where the body includes a forward end and a rearward end that supports engagement with a charging dock. In addition, the rearward end accepts engagement of a snap-on module that physically assembles to and electronically interfaces with the mobile device. The antennas or sensors are externally mounted to the mobile device at a location proximate to the forward end of the body. Further, these antennas or sensors are interconnected to the snap-on module using media-routing conduit(s) that are configured to carry signals from the antennas or sensors to the snap-on module for distribution as an input to the application running on the processing unit.
Abstract:
A printing apparatus is described that comprises an antenna configured to intercept radio waves modulated with printing data; a receiver configured to recover the printing data from the intercepted radio waves; a printing module configured to generate a printed output on a printing medium based on the printing data; and a housing for the printing apparatus, wherein the housing encloses the antenna, the receiver, and the printing module, and further wherein the antenna is integrated with an interior surface of the housing.
Abstract:
A reconfigurable antenna element is controlled using a wirelessly powered and wirelessly activated switch, where the antenna element is part of an antenna or antenna array. A control signal for reconfiguring the antenna element is embedded into a wirelessly transmitted data signal for transmission by the antenna.
Abstract:
An apparatus for use in an RFID data collection system includes an antenna portion for wirelessly exchanging signals and a memory portion for storing RFID data. A signal processing portion is coupled among the antenna portion and the memory portion. The signal processing portion is configured to receive RFID data and to at least encode or decode the received RFID data via at least one spreading code, such as a mutually orthogonal code. Other configurations are also disclosed.
