A method and device for storing an interactive television program for playback at a later point in time, wherein said interactive television program comprises at least one interactive television application. The applications are transmitted inside modules (11, 12) through a data carousel (2) within a transport stream (20). The method comprises receiving the transport stream, parsing the stream for application modules and storing them as a storage stream on a storage medium (31). The storage stream is stored separate from said transport stream (20). The data or object carousel is recorded outside the Transport Stream and recorded like a stream, preferably as a single file. This file is a sequence of modules with some header information preceding the modules making playback faster as the information needed to obtain the objects from a module is located directly in the header of that module. Furthermore, the solution according to the invention solution is platform independent.

A multi-resolution codebook is used to provide quantization for channel related information in a wireless network that supports both single-user MIMO and multi-user MIMO. The multi-resolution codebook may include a higher resolution “fine” codebook for use with MU-MIMO subscriber stations and a lower resolution “coarse” codebook for use with SU-MIMO subscriber stations. A tracking codebook may also be used to provide quantization for updates to channel related information. In at least one embodiment, the tracking codebook includes a number of unit vectors (or orthogonal matrices) disposed upon a sphere cap.

System and method are disclosed for synchronization of a transmitting device and a receiving device that communicate with each other via pulse modulation. The synchronization technique entails the transmitting device sending one or more quasi-periodic pulse sequences to the receiving device. A quasi-periodic pulse sequence is based on a substantially periodic pulse sequence, and may include some non-periodic pulses or not include some periodic pulses. The transmitting device may transmit frames each including a preamble that comprises one or more quasi-periodic pulse sequences, and a data payload that may comprise data. The receiving device receives the signal, generates samples of the signal, and detects the quasi-periodic pulse sequences in the received signal by analyzing samples based on a sample associated with a pulse and the period associated with the substantially periodic pulse sequence. The receiving device is further able to detect frames based on the detection of the sequence, and extract data therefrom.

An erosion resistant coating for a substrate includes two or more coating layers affixed to the substrate having an increasing modulus of elasticity and hardness from an innermost layer of the coating adjacent to the substrate to an outermost layer of the coating furthest from the substrate. A method of applying a coating system to a substrate includes applying a first layer of a high hardness and high modulus of elasticity material combined with an added metal to the substrate. A second layer of the high hardness and high modulus of elasticity material combined with the added metal is applied to the first layer, resulting in a coating system wherein the second layer has a modulus of elasticity and hardness greater than the modulus of elasticity and hardness of the first layer.

Compensation is provided for errors in channel information that can result when there is a delay between the measurement of the channel information and the subsequent use of the channel information. In one embodiment, downlink channel prediction is performed within a user device, in a system employing closed loop MIMO with implicit feedback, to reduce the occurrence of errors during the calculation of a calibration parameter within an associated base station. In another embodiment, channel prediction is used to predict a downlink channel state for a user device at a future time when a multi-user MIMO data transfer is to occur between a base station and a number of selected user devices.

A method that involves matching the trend of process outcome with the trend of process variables to identify the variables that have an impact on the process outcome is disclosed. The method for process trend matching comprises processing of raw data of process outcome and of process variables using an outlier filtering method, smoothing these data using common smoothing algorithm like Kernel, dividing smoothed raw data equally into time intervals, computing the gradients of the points at both ends of the time intervals, and translating the gradients into a scale based on the magnitude of the gradients. The following steps comprise comparing the process outcome and each process variable independently for same time frame, and assigning a score for both outcome and variable. The sum of the scores is then computed which is used to determine the quality of fit. A real-time monitoring system is then set up to monitor these variables for any drifts. When a drift is detected, troubleshooting activity will be triggered and actions taken to resolve the drift, after which monitoring of the variable will be restarted.
