| 20100179446 | DEVICE AND PROCEDURE FOR VISUAL THREE-DIMENSIONAL PRESENTATION OF ECG DATA - The analysis of ECG (electrocardiogram) data by exploiting computerized three-dimensional spatial presentation of the measured data using the vector concept. A three-dimensional presentation of the human heart may be correlated with waveforms specific for standard ECG or derived ECG signals based on the dipole approximation of the heart electrical activity. The three-dimensional heart model may be rotated, and the ECG signals are interactively linked to the model. Cardiac ischemia (inadequate blood supply) is detected by calculating an ECG ST-segment vector magnitude or an ST-T spatial angle change of a heart vector from the heart model and comparing these to respective predetermined ischemia criteria, using actual or virtual ECG lead sites. | 07-15-2010 |

| 20090199008 | Watermarking digital representations that have undergone lossy compression - Techniques for watermarking digital representations such as MPEG audio frames that spread the watermark information across the entire audio frame. The techniques work in conjunction with lossy compression techniques and are compatible with the perception models that are often used with lossy compression techniques. The watermark information is spread by means of transformations between the space/time domain and the frequency domain. When a MPEG audio frame is being watermarked, the compressed audio frame as it is produced by the quantizer is transformed from the frequency domain to the time domain; the time domain transformation is then randomized using a key and the randomized time domain transformation is transformed into the frequency domain. The watermark information is added at a predetermined frequency in the frequency domain transformation and the sequence of transformations is done in reverse order, with the randomization and derandomization serving to distribute the watermark information across the frequency domain representation of the watermarked audio frame. | 08-06-2009 |

| 20100128703 | Method for Routing Packets in Wireless Ad-Hoc Networks with Probabilistic Delay Guarantees - A method determines an optimal route to deliver a packet from a source node via relay nodes to a destination node in a network. A graph of nodes connected by edges represents possible routes in the network. A probability that the packet arrives at the destination before a deadline time is assigned to each edge. A minimal delay route is selected from the possible routes, and an arrival time for delivering the packet using the minimal delay route is determined. The arrival time is comparing to a deadline time, and the probabilities are scaled accordingly until the minimal delay route is an optimal route. | 05-27-2010 |

| 20080311336 | Foam Laminate Product and Process for Production Thereof - A laminate product comprising a foam core having a pair of opposed major surfaces and a cover layer secured with respect to each major surface is described. The cover layer comprises a polymeric substrate having disposed therein a plurality of reinforcing fibrous material. It has been found that it is possible to produce a foam laminate product having improved stiffness if a lower amount of reinforcing material is used for a given amount of polymer substrate. In particular, it has been found possible to provide an improved foam laminate product having a relatively high ratio of stiffness to weight of reinforcing fibrous material. It has been further discovered that the stiffness of the resulting foam laminate product can be increased when the polymer substrate and the reinforcing fibrous material are present in a weight ratio of greater than 2.5. This is believed to be the result of improved encapsulation of the reinforcing fibrous material by the polymer substrate. | 12-18-2008 |
