International Classification:

H04N 7/18
G08G 1/01

US Classification:

725 74, 340933

Abstract:

Embodiments of the invention relate to a method, system and computer-readable medium for conveying audio/video information. The method detects a presence of at least one automobile and communicates such presence to an information system comprising a number of display devices (D) and an information processing unit. The processing unit contains a library of audio/video portions, each audio/video portion having a total run time (V), where each audio/video portion is divisible into segments (V) having a segment run time (V) such that V≦Dand V÷D=V. The processing unit estimates a total viewing time (T) to provide the audio/video information; parses the audio/video information into Dseparate segments; and selects one parsed audio/video portion such that Vof the selected audio/video portion is substantially equal to TThe selected audio/video segments are communicated to the display devices.

International Classification:

B05D 306
B05B 502

US Classification:

427 42

Abstract:

A coating of metallic material is deposited on the internal surface of a hollow object. An elongate member comprising two electrical conductors extending side-by-side from end-to-end of the member has one end inside the hollow object and its opposite end outside the object. A filament has its two ends connected to the conductors respectively at the one end of the elongate member, and a crucible containing metal to be deposited is supported above the filament and in spaced relationship thereto. By supplying current to the filament by way of the conductors for the filament is heated to achieve thermonic emission. The filament and the crucible are connected to negative and positive terminals respectively of a potential source so that electrons emitted by the filament are accelerated towards the crucible and cause the crucible to be heated by electron bombardment.

International Classification:

B22F 312

US Classification:

75214

Abstract:

Metallic sputtering targets having minimal mobile ion contamination are produced by forming a compacted slab of particles of the constituent metal(s) in an isostatic pressing operation. The slab is then transferred to a heat resistant support faced with a material, such as alumina, that is inert at high temperatures. Next, the supported slab is placed in a vacuum oven and heated to a temperature sufficient to bond the metal particles together and volatilize mobile ion contaminants. The sintered slab is usable as a cathodic sputtering target with minimal additional treatment. The level of mobile ion contaminants in the completed target may be monitored by fabricating an MOS capacitor using the target, plotting its capacitance versus applied voltage over a suitable range, then measuring the extent to which the plot shifts after a high temperature-positive bias stress treatment.

Assignee:

Tektronix, Inc. - Beaverton OR

International Classification:

C25D 554

US Classification:

204 38B

Abstract:

A method of fabricating a hybrid circuit including a siliceous substrate and thick metal conductors. A thin film barrier layer is provided intermediate the substrate and a vacuum-deposited metal layer, which metal layer is subsequently electroplated to provide the desired metal thickness. The barrier layer, which may suitably be a refractory metal oxide such as the oxides of zirconium, tantalum, titanium, or tungsten, prevents loss of adhesion between the vacuum deposited metal and substrate that occurs during electroplating.

International Classification:

H05K 109

US Classification:

174 685

Abstract:

A thin-film metal conductor system using a zirconium adhesion layer is disclosed. The system is formed by first plating a layer of zirconium over a substrate material and any electrical components, such as resistors, which are fixed on the substrate. A conductive layer is then deposited over those portions of the zirconium layer which are to provide conductive pathways. The resulting unit is thermally treated in an oxidizing environment, such as air, to oxidize the exposed portions of the zirconium layer and thereby form regions of zirconium oxide. The zirconium oxide is nonconductive and protects underlying components from moisture and physical abrasion.
