Abstract: A media drying system removes a moistening liquid from a moistened medium, the moistening liquid having a moistening-liquid boiling point. A liquid reservoir contains a heating liquid. A liquid-heating system warms the heating liquid in the liquid reservoir to a temperature greater than the moistening-liquid boiling point. A media-transport system transports the moistened medium along a transport path which passes through the liquid reservoir. The moistened medium is submerged in the warmed heating liquid and heat is transferred from the warmed heating liquid to the moistening liquid. This vaporizes the moistening liquid and removing it from the moistened medium.

Abstract: A media drying system removes a moistening liquid from a moistened medium having first and second surfaces. A liquid reservoir contains a heating liquid heated above a moistening-liquid boiling point. A rotatable liquid-blocking member has a liquid-blocking layer with an inner surface and an outer surface. A media-transport system transports the medium entrained around the liquid-blocking member so that the first surface of the moistened medium is brought into contact with the outer surface of the liquid-blocking layer. An entrained portion of the moistened medium passes through the liquid reservoir and is submerged in the warmed heating liquid. The heating liquid contacts the inner surface of the liquid-blocking layer so that heat is transferred through the liquid-blocking layer from the warmed heating liquid to the moistening liquid, or heat is transferred from the warmed heating liquid to the second surface of the moistened medium.

Abstract: A media drying system removes a moistening liquid from a moistened medium. A liquid reservoir containing a heating liquid heated above a moistening-liquid boiling point. A rotatable liquid-blocking member has a liquid-blocking layer with an inner surface and an outer surface. A media-transport system transports the moistened medium so it contacts or is entrained around the liquid-blocking member in a path zone so that the moistened medium is brought into contact with the outer surface of the liquid-blocking layer. A porous material absorbs heating liquid from the liquid reservoir and brings the absorbed heating liquid into contact with the inner surface of the liquid-blocking layer for at least a portion of the path zone. Heat is transferred through the liquid-blocking layer from the absorbed warmed heating liquid to the moistening liquid, vaporizing the moistening liquid and removing it from the moistened medium.

Abstract: An electroluminescent (EL) device with aging compensation has a luminance and a chromaticity that both correspond to the density of the current and the age of the EL emitter. Different black, first and second current densities are selected based on the measured age, each corresponding to emitted light colorimetrically distinct from the light emitted at the other two current densities. Respective percentages of a selected emission time are calculated for each current density to produce a designated luminance and chromaticity. The current densities are provided to the EL emitter for the calculated respective percentages of the emission time so that the integrated light output of the EL emitter during the selected emission time is colorimetrically indistinct from the designated luminance and chromaticity, no matter the age of the EL emitter.

An electrical excitation signal is passed through the code circuit, and a corresponding received electrical signal detected, using a transceiver formed on a transceiver substrate separate from and disposed over the substrate, wherein the transceiver includes a controller and the received electrical signal depends on the excitation signal and the electrical state of the code circuit. Using the controller, the received electrical signal or a representation thereof is automatically stored in a memory. The checking and storing steps are automatically repeated after one or more selected time intervals.

Abstract: An electronic sensing system has a transceiver with input and output pads, an excitation circuit connected to the output pad, and a detection circuit connected to the input pad. An electrically-conductive sensor patch has an electrical state that changes with exposure to a corresponding environmental factor. The detection circuit detects an electrical state of the input electrical-connection pad in response to the excitation signal and the electrical state of the sensor patch. A stack of one or more layers in order is disposed over the sensor patch in the detection region. Each layer is susceptible to a respective environmental factor, so that the sensor patch changes electrical state in response to exposure of the layer stack to the respective environmental factors of the one or more layer(s) in the selected order and subsequent exposure of the sensor patch to the corresponding environmental factor.

Abstract: An electronic sensing system has a transceiver with input and output pads, an excitation circuit connected to the output pad, and a detection circuit connected to the input pad. An electrically-conductive sensor patch has an electrical state that changes with exposure to a corresponding environmental factor. The detection circuit detects an electrical state of the input electrical-connection pad in response to the excitation signal and the electrical state of the input pad. Several electrically-conductive sensor patches are distributed over the substrate so that they are exposed to an external environmental factor substantially contemporaneously, each having a conductance susceptible to a respective environmental factor. The output pad is electrically connected to the input pad through the sensor patches in series, so that the detection circuit detects an electrical state of the input pad in response to the excitation signal and the respective conductances of the sensor patches.

Abstract: An electroluminescent (EL) panel with 2T1C subpixels is compensated for initial nonuniformity (“mura”). The current of each subpixel is measured at a selected time to provide a status signal representing the characteristics of the subpixel. A compensator receives a linear code value and changes it according to the status signals. A linear source driver drives the panel with the changed code values.

Abstract: A bound document having a plurality of sheets is produced. Image data for a cover image is received and dividing along a sheet-edge curve into first and second image portions. The first image portion is printed on an inner cover sheet so that an alignment location is defined on the inner cover sheet corresponding to the sheet-edge curve. The inner cover sheet and the plurality of sheets are bound together. The second image portion is printed on an outer cover sheet, and is printed borderlessly with respect to a selected edge of the outer cover sheet. After the binding step, the outer cover sheet is affixed to the inner cover sheet so that the selected edge aligns with the alignment location to form the bound document.

Abstract: An RFID reader communicates with an RFID tag of a masked container in a container group. A power-supply antenna and a link antenna of the RFID reader are spaced apart from the container group, the antennas oriented to transmit signals to a power-supply subset and a data subset, respectively, of the plurality of containers. The RFID reader transmits a power-supply RF signal via the power-supply antenna to the power-supply subset and, while doing so, transmits a data RF signal via the link antenna to the data subset. The containers relay power-supply RF energy in a downstream power-supply direction and relay the data RF signal in upstream and downstream data directions different from the power-supply direction. The data RF signal is relayed by a repeater, which is powered by relayed power-supply RF energy, on each container. The RFID tag responds to the relayed data signal.

A data signal is transmitted to a second subset of the containers facing a link antenna. The power and link antennas face non-parallel sides of the container. The containers pass power back from the first subset. The power transmitted to each container runs an RFID repeater that passes data back from the second subset. In the container group is a masked container with an RFID tag that communicates with the RFID repeater on the next container closer to the link antenna.
