Abstract: Assets of broadcast network content are targeted to network users of interest based on location information regarding user equipment devices. Asset providers can specify location targeting criteria via a graphical user interface displaying mapping information. This location targeting criteria can then be compared to location information regarding user equipment devices so that assets are delivered to appropriate devices. The comparison of the location targeting criteria to the device location information can be performed at the user equipment devices or at another location. In the latter case, the assets can be addressed to appropriate user equipment devices or appropriate user equipment devices can be directed to select the asset, which is broadcast via the network. In this manner, assets can be targeted to individual network users on a basis independent of network topology.

Abstract: Methods for recovering high-resolution images from an analog video interface by autonomously correcting for phase errors between a synchronized clock signal to a sampling analog-to-digital converter and the input video signal. A global phase adjustment first detects video transitions in the sampled video data stream in order to determine and then select the optimum clock phase over entire video frames for rendering the pixels of the video input. This corrects for long-term phase errors, such as those from timing tolerances in circuit components and timing tolerances in the video input. A local phase adjustment selects the samples used for rendering individual pixels according to an algorithm that avoids the selection of samples that may be located within video transition regions. This corrects for short-term phase errors, such as those from jitter and phase drift on the sample clock.

Abstract: In a method of producing TiO.sub.2 pigment particles a TiO.sub.a X.sub.b (OH).sub.c -based precursor is suspended in a liquid with or without fuel additives. The suspension is then sprayed to form droplets. The droplets are transported into a flow reactor with a carrier gas. The droplets are decomposed in the flow reactor at high temperatures to form TiO.sub.2 pigment particles which are collected downstream of the flow reactor. In a preferred embodiment, a colloidal suspension of an insoluble TiO(SO.sub.4).sub.b (OH).sub.c precipitate with suitable fuel additives was spray-calcined at 900.degree. to 1200.degree. C. to produce pigment-quality TiO.sub.2. The primary particle size of the TiO.sub.2 pigment particles is between 150-250 nm and the particles are minimally aggregated.

Abstract: The vector generator employs a digital accumulator for each vector component. The accuracy of generated vectors is optimized by presetting the fractional portions of the accumulators to a value of either 1/2 or to 1/2 less 1 LSB. Accumulation of errors over concatenated vectors is eliminated by employing high enough fractional resolution relative to the maximum vector length so that error accumulation on any single vector is limited to the fractional portions of the accumulators, and by setting the fractional portions of the accumulators, on the last clock cycle of each vector, to a value of 1/2 to 1/2 less 1 LSB. Also, by setting/presetting the fractions to only 1/2 less 1 LSB, and by enabling the carry input to a given accumulator on only the first clock cycle of vectors that have certain orientations, then symmetry is forced or favored in complex symbology that is generated by concatenated vectors.

Abstract: Method for reduction in metallic impurities in aqueous and anhydrous TiCl.sub.4. The method utilizes activated carbon to remove poisonous impurities such as antimony and arsenic, which allows use of the TiCl.sub.4 in pearlescent pigment production and cosmetics.
