Abstract: An aqueous polymer coating composition containing at least one latex or pseudolatex is coated on a substrate in a high humidity coating process followed by heat treatment of the coated substrate above the film forming temperature of the coating at low humidity. The coated substrate gives a stable reproducible dissolution profile substantially insensitive to temperature or humidity conditions upon storage. The high humidity coating process is achieved by addition of water to the coating chamber through dilution of the coating formulation or humidification of inlet air. Contrary to the conventional low humidity coating process, residual water is retained in the coating layer of the coated substrates in the coating step. When the coated substrates are heat treated at a temperature greater than the minimum film forming temperature, the residual water in the coating layer will ensure adequate capillary force for the completion of film coalescence. High humidity heat treatment is not needed.

Abstract: A method and apparatus for compressing compound images of the type containing text, graphics and photographic imagery. This method and apparatus offer significant simplicity and computational efficiency by progressing fundamentally through a first processing phase, wherein an original compound image is first separated into (1) a foreground (text and graphics) layer, and (2) a more pixel-complicated background (photographic imagery) layer, all based upon a simple region-growing segmentation algorithm, and then a follow-up phase which involves individual and differentiated compression of the two segmented layers. Simple regional boundary encodation is employed for the foreground layer, and a lifting-scheme-modified ASWT algorithm is employed for the background layer.

Abstract: A method in a scalable encoder for reducing the average latency associated with randomly accessing an encoded digital video signal is disclosed. This method may include converting a digital video signal into a first layer having a first degree of quality and a second layer having a second degree of quality that is higher than the first degree of quality. The method may also include encoding the first layer at a first intra-frame rate, and encoding the second layer at a second intra-frame rate that is lower than the first intra-frame rate. A method in a scalable decoder for reducing the average latency associated with randomly accessing an encoded digital video signal is also provided. The method includes accessing a first layer of a digital video signal. The first layer includes the digital video signal encoded at a first degree of quality and a first intra-frame rate. The method also includes accessing a second layer of the digital video signal. The second layer includes the digital video signal encoded at a second degree of quality higher than the first degree of quality and a second intra-frame rate lower than the first intra-frame rate.

Abstract: A method of data compression. A multiple-level wavelet transform transforms image data of an original image. Motion compensation is performed on a low-frequency band of the transformed image data. This band is then inversely transformed and used to reconstruct a portion of the original image. The remaining portions of the original image are then reconstructed from that portion. This image data then becomes the basis of the next level of the wavelet transform and is transformed back into the wavelet domain. This process is repeated until all of the levels of the wavelet transform have been used.

Abstract: A graphical user interface for a videophone in a cable television system allows the user to access the videophone functionalities with an input control device and a television monitor. The user can place a call, receive a call and store/access/call addresses using a remote in conjunction with the graphical user interface display screens. The videophone has several elements including a user interface, a graphics engine, a network interface, a remote control interface, and an output audio/video line connected to a television monitor. The user interface receives and processes control inputs using a microprocessor and the graphics engine generates the display screens using a DSP. Depending on processing requirements, the DSP may implement the user interface rather than the microprocessor. Also, anti-aliasing fonts are used to generate a high quality display. To save processing cycles, the anti-aliasing fonts may be retrieved from a look-up table rather than being generated in real time. The videophone may be implemented as a plug-in device to a set-top box, a standalone unit, or a standalone unit with a set-top box between the monitor and the videophone unit. When implemented with a set-top box the same remote control unit may be used to control the television and videophone functions.

Abstract: A scintillation-crystal based gamma-ray detector with photon sensors disposed on edge surface(s) of the crystal to take advantage of total internal reflection of scintillation photons within the thin-slab detector substrate to improve spatial resolution of determination of a scintillation event (including depth-of-interaction resolution) while preserving energy resolution and detection efficiency. The proposed structure benefits from the reduced—as compared with related art—total number of readout channels elimination of need in complicated and repetitive cutting and polishing operations to form pixelated crystal arrays used in conventional PET detector modules. Detectors systems utilizing stacks of such detectors, and methods of operation of same.
