A four-color transmissive display system incorporates a display having independently variable light sources for different colors, and a controller. The controller is configured to receive and process a three-color input image signal, and provide a four-color output image signal to the display. The controller incorporates units respectively configured to (1) calculate a blue reduction factor for each pixel, dependent on luminance differences between blue and other color components, (2) produce respective saturation adjustment factors for red, green, and blue, (3) apply the blue reduction factor to reduce blue luminance, and apply the saturation adjustment factors to reduce saturation of other colors, (4) produce the output image signal. An optional sensor is operable to provide a control signal to the controller, whereby display power can be reduced. An optional estimating unit is configured to estimate current required to display the input image signal, for adjustment of the output image signal.

Apparatus for reading an RFID tag includes an RF-blocking enclosure having a port and adapted to receive through the port a non-RFID-active object having an RFID tag affixed thereto. An RFID reader has a reader antenna located outside the enclosure. The antenna transmits an RF downlink signal in a particular direction. An RF grating is arranged between the reader antenna and the port so that, after the enclosure receives the object having the tag, the port is located in the transmit direction from the reader antenna, and RF energy transmitted from the reader antenna has a selected linear polarization after passing through the grating.

A display securely decrypts an encrypted image signal. Pixels are disposed between the display substrate and cover in a display area, and provide light to a user in response to a drive signal. Control chiplets disposed between the display substrate and cover in the display area are each connected to one or more of the plurality of pixels. Each receives a respective control signal and produce respective drive signal(s) for the connected pixel(s). A decryption chiplet is disposed between the display substrate and cover. It includes means for receiving the encrypted image signal and a decryptor for decrypting the encrypted image signal to produce a respective control signal for each of the control chiplets.

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.

A media drying system removes a moistening liquid from a moistened medium, the moistening liquid having a moistening-liquid boiling point. A liquid-supply system provides a heating liquid. A liquid-heating system warms the heating liquid to a temperature greater than the moistening-liquid boiling point. A liquid-delivery system impinges the warmed heating liquid onto a surface of the moistened medium. Heat is thus transferred from the heating liquid to the moistening liquid, vaporizing the moistening liquid and removing it from the moistened medium.

Dryer impinging heating liquid onto moistened medium

A media drying system removes a moistening liquid from a moistened medium. A heating member rotatable around an axis has a liquid-blocking layer with an inner surface and an outer surface. A backing layer affixed to the liquid-blocking layer defines a liquid cavity not including the axis. A heating liquid heated above a moistening-liquid boiling point is sealed between the liquid-blocking layer and the backing layer and in contact with the inner surface. A media-transport system transports the moistened medium so it contacts or is entrained around the liquid-blocking member. The moistened medium contacts the outer surface of the liquid-blocking layer, heat is transferred through the liquid-blocking layer from the warmed heating liquid to the moistening liquid, and the moistening liquid is vaporized and removed from the moistened medium.

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.

A method for fixing toner onto a receiver medium includes depositing a pattern of toner onto a surface of the receiver medium. A liquid-blocking barrier is provided that has a first surface and a second surface that is impermeable to a heating liquid. The surface of the receiver medium is brought into contact with the first surface of the liquid-blocking barrier. The heating liquid is brought into contact with the second surface of the liquid-blocking barrier. The heating liquid is at a temperature greater than the toner glass transition temperature. Heat is transferred through the liquid-blocking barrier from the heating liquid to the toner, thereby raising the temperature of the toner to a temperature above the toner glass transition temperature.

A container group includes a plurality of containers arranged in three dimensions. A power signal is transmitted to a first subset of the containers facing a power antenna. 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.
