A document rights management system (DRM) defines an unrenderable origin designator in a media item that does not display or alter the physically rendered version of an instantiation of the media item. The unrenderable designator does not appear as an obscured or occluded feature in a printed or displayed versions. The rendered version is unaffected by the unrenderable designator because it does not result in any displayable features.

Single sensor radio scene analysis for packet based radio signals using 2nd and 4th order statistics
We consider a problem of radio frequency (RF) signal analysis where one sensing node observes a frequency band possibly used by multiple packet based radio transmitters. Analysis of the received signal includes two steps. In the first step we use a spectrogram to perform temporal segmentation of the received nonstationary signal. This task may be formulated as a clustering problem. In the second step we compute a certain 2-D slice of the fourth order spectrum for each of the segments found in the first step. These fourth order spectrum slices are arraigned in a three-way array. One aspect of the second step is to use uniqueness properties of the low rank decomposition of the three-way array to recover spectra and associated activity sequences of individual components in the received signal. We derive a numerical algorithm for the low rank decomposition, which computes estimates of the spectra and activity sequences by optimizing certain weighted least squares criterion under application specific constraints. Certain embodiments are illustrated with simulation examples involving signals used in 802.11a/b/g and Bluetooth networks. The disclosed methods and related systems can be used as spectrum analysis tools, providing crucial information needed for achieving efficient utilization of radio spectrum and elimination of mutual interference between the coexisting systems.

An improved loss recovery method for coding streaming media classifies each data unit in the media stream as an independent data unit (I unit), a remotely predicted unit (R unit) or a predicted data unit (P unit). Each of these units is organized into independent segments having an I unit, multiple P units and R units interspersed among the P units. The beginning of each segment is the start of a random access point, while each R unit provides a loss recovery point that can be placed independently of the I unit. This approach separates the random access point from the loss recovery points provided by the R units, and makes the stream more impervious to data losses without substantially impacting coding efficiency. The most important data units are transmitted with the most reliability to ensure that the majority of the data received by the client is usable. The I units are the least sensitive to transmission losses because they are coded using only their own data. While they provide the best coding efficiency, the P units are the most sensitive to data loss because the loss of one P unit renders useless all of the P units that depend on it. The remotely predicted units are dependent on the I unit, or in an alternative implementation, on another R unit.

A channel structure has at least two channel sets. Each channel set contains multiple channels and is associated with a specific mapping of the channels to the system resources available for data transmission. Each channel set may be defined based on a channel tree having a hierarchical structure. To achieve intra-cell interference diversity, the channel-to-resource mapping for each channel set is pseudo-random with respect to the mapping for each remaining channel set. In each scheduling interval, terminals are scheduled for transmission on the forward and/or reverse link. The scheduled terminals are assigned channels from the channel sets. Multiple terminals may use the same system resources and their overlapping transmissions may be separated in the spatial domain. For example, beamforming may be performed to send multiple overlapping transmissions on the forward link, and receiver spatial processing may be performed to separate out multiple overlapping transmissions received on the reverse link.

The input ports can be amplified with single ended amplifiers, attenuated with a loss network, combined and re-amplified with a second amplifier stage. The amplifier distortion performance, loss and gain levels can be chosen such that the second order distortions of the input port amplifier and the amplifier following a combiner are self-cancelling such that the distortion can be reduced. The obtained distortion performance can be reasonable while gain and signal to noise ratio are improved.

The invention relates to devices comprising field effect transistors to detect the power of an electromagnetic high frequency signal VRF. According to the prior art, the high frequency signal is coupled into the gate G and via a capacitor CGD into the drain D of the field effect transistor FET, the gate G being biased with a direct voltage Vg which corresponds to the threshold value of the FET transistor. The resulting current at the source S contains a direct current portion Ids which is proportional to the square of the amplitude of the high frequency signal. The operating frequency of said power detectors is limited to a few gigahertz (GHz) by the discrete arrangement and especially by the predetermined gate length of the field effect transistor. The aim of the invention is to improve a resistive mixer in such a manner that it can be operated at high gigahertz and terahertz frequencies. For this purpose, the resistive mixer comprises a line which has a first and a second electrical conductor having respective connecting contacts so that an electrical high frequency signal can be coupled into the line, the first conductor having a plurality of series-connected voltage-dependent resistor elements (R) and at least one capacitive element (C) being interposed between the first and the second conductor.
