Abstract: Signal processing technology for assessing dynamic system similarity for fault detection and other applications is based on time- and frequency-domain time series analysis techniques and compares the entire autocorrelation structure of a test and reference signal series. The test and reference signals are first subjected to similar pre-processing to help guarantee signal stationarity. Pre-processing may include formation of multivariate signal clusters, filtering and sampling. Multivariate periodograms or autocovariance functions are then calculated for each signal series. Test statistics are computed and assessed to determine the equality of the test and reference signals. When the difference between sample autocovariance functions or periodograms of such signals exceeds a preselected threshold value, fault detection signals and/or related diagnostic information are provided as output to a user.

Abstract: A display system utilizes a tilting sensor in a viewing device to transmit a wireless signal containing tilting information to a display device when a person who puts on the viewing device has tilting movements about an axis that connects between the viewing device and the display device. The display device adjusts a multimedia content displayed on a panel according to the tilting information by physically rotating the panel about the same axis or rotating the multimedia content about the same axis before the content is displayed on the panel to synchronize with the tilting angle of the viewing device.

Abstract: A method displays the remaining range of a motor vehicle. The method determines repeatedly estimated values relating to the remaining range of the motor vehicle based on a fill level of an energy storage unit and at least one additional motor-vehicle state influencing the remaining range. A first remaining-range value is determined based on the estimated values and displayed as a first display value by a first graphical element on the display device. An updated second remaining-range value is determined during the display of the first display value. If the difference, in terms of amount, between the first and the second remaining-range values exceeds a predetermined threshold value, the second remaining-range value is displayed as a second display value by a second graphical element in addition to the first display value on the display device.

The RFID system operating method includes the steps of grouping RFID readers spaced apart by more than a spacing distance capable of avoiding collision between RFID readers into a single group to determine at least one group, classifying RPM readers included in each group into at least one sub-group based on a read time of each RFID reader, and driving the RFID readers such that RPM readers belonging to at least two different sub-groups that do not collide with each other simultaneously operate. According to the present invention, switching is performed sub-group by sub-group to reduce the number of switching operations and sub-groups can simultaneously operate to decrease a read time.

Abstract: The present invention supports the remote control of a controlled device. A hybrid device receives a control signal over an infrared communications channel or a wireless networking channel. The hybrid device can replace an IR receiver module in the controlled device in order to provide backward compatibility as well as provide universal operation with a wireless networking controller. The hybrid device processes a signal received over one of the communications channels. When a signal is received over the infrared communications channel, the processor converts the signal to an output code that is sent to a device controller. When a signal is received over the wireless networking communications channel, the processor converts the signal to a wireless command, converts the wireless command to an output code, and sends the output code to the device controller. All output codes are transparent for the two communications channels.

Abstract: The present invention discloses a method, system, and computer program product for determining user interest in media. The invention can select one of a set of different activity profiles specified within a data store. Each activity profile can include biometric attributes and associated baseline attribute values specific to an activity state. A media stream can be manipulated (e.g., created from environmental inputs and/or played upon a presentation device). Biometric data can be received from a user in proximity to the media stream. The received biometric data can be compared values in the selected activity profile. An interest level in the media stream can be determined based on comparison differences. A programmatic action can be performed relating to the media stream based upon the determined interest level. For example, a bitrate of the media and/or a marker in the media can be modified based on interest level.
