摘要:
A method of sensing exposure to one or more of a plurality of environmental factors includes exposing a code circuit to at least some of the environmental factors, the code circuit disposed over a substrate and including a plurality of electrically-connected sensor patches, each sensor patch susceptible to one of the environmental factors, wherein the code circuit has an electrical state. 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.

An electroluminescent display includes a display substrate, a plurality of patterned first electrodes formed over the display substrate, one or more layers of light-emitting material formed over the plurality of first electrodes, at least one second electrode formed over the one or more layers of light-emitting material, and a plurality of chiplets. Each chiplet is electrically connected to a first electrode. Each chiplet further includes a light detector and a light emitter separate from the one-or-more layers of light-emitting material connected to the chiplet circuitry. The chiplet circuitry includes a modulating circuit for modulating light emitted by the light emitter and a demodulating circuit for demodulating light detected by the light detector so that light emitted by the light emitter of a first chiplet is received by the light detector of a second chiplet.

A method of making a shaped electrical conductor (610, 630) includes providing a first sheet of metal (319) and applying a first and second thermoplastic adhesive pattern (311, 312) to a first and a second surface thereof. The second pattern is are fully justified with the applied first pattern. The first sheet is etched to remove metal not covered by the patterns so that no metal bridges remain between disconnected coated portions. A second sheet of metal (339) is provided and a third and fourth thermoplastic adhesive pattern (333, 334) is applied to a first and second surface thereof. The third and fourth patterns are fully justified. The second sheet is etched as for the first sheet. Contact regions (315, 335) in the second and third patterns are joined to form electrical contact between the first and second sheets.

A method is provided in one example embodiment and includes evaluating an active state of a media server configured to capture a media stream from one or more media sources. The method also includes determining a failure associated with the media server, and activating a failover media server to receive the media stream based on the failure. The method further includes replicating configuration data associated with the media server that experienced the failure. The configuration data can be provisioned in a suitable database. The failover media server is configured using the configuration data.

A color display system includes an illumination system that provides a temporal sequence of illumination color channels, and a monochrome reflective display system including a directly-viewable display surface having display pixels with a controllable reflectance. The display system detects an active illumination color channel being provided by the illumination system and controls the reflectance of the display pixels according to image data for a corresponding image color channel. When no illumination color channel is being provided to the display surface, the display pixels are controlled to display a monochrome image determined from the color image data.

An apparatus for detecting variations in light output of an electroluminescent (EL) device is described. The EL device includes a transparent substrate having a first edge extending in a first direction and a plurality of EL emitters disposed over the face of the substrate in the first direction, and some of the light emitted by each EL emitter travels through the substrate and out of the first edge. A light sensor physically separated from the first edge senses the light travelling out of the first edge. A controller stored first sensed light at a first time and second sensed light at a later second time and computes a variation in light output of one or more of the EL emitters in the EL device using the stored first sensed light and second sensed light.

Network traffic information from multiple sources, at multiple time scales, and at multiple levels of detail are integrated so that users may more easily identify relevant network information. The network monitoring system stores and manipulates low-level and higher-level network traffic data separately to enable efficient data collection and storage. Packet traffic data is collected, stored, and analyzed at multiple locations. The network monitoring locations communicate summary and aggregate data to central modules, which combine this data to provide an end-to-end description of network traffic at coarser time scales. The network monitoring system enables users to zoom in on high-level, coarse time scale network performance data to one or more lower levels of network performance data at finer time scales. When high-level network performance data of interest is selected, corresponding low-level network performance data is retrieved from the appropriate distributed network monitoring locations to provide additional detailed information.

An electroluminescent (EL) device including an illumination area having one or more primary EL emitters; a reference area having a reference EL emitter; a reference driver circuit for causing the reference EL emitter to emit light while the EL device is active; a sensor for detecting light emitted by the reference EL emitter; and a measurement unit for detecting an aging-related electrical parameter of the reference EL emitter while it is emitting light. The device further includes a controller for receiving an input signal for each primary EL emitter in the illumination area, forming a corrected input signal from each input signal using the detected light and the aging-related electrical parameter, and applying the corrected input signals to the respective primary EL emitters in the illumination area.
