Abstract: An electronic device may be provided with control circuitry, wireless transceiver circuitry, and a display. The electronic device may be used to provide information to a user in response to being pointed at a particular object. The control circuitry may determine when the electronic device is pointed at a particular object using wireless control circuitry and/or motion sensor circuitry. In response to determining that the electronic device is pointed at a particular object, the control circuitry may take suitable action. This may include, for example, displaying information about an object when the electronic device is pointed at the object, displaying control icons for electronic equipment when the electronic device is pointed at the electronic equipment, and/or displaying a virtual object when the electronic device is pointed at real world object.

Abstract: Methods, computing devices, and magnetic resonance imaging systems that improve image quality in turbo spiral echo (TSE) imaging are disclosed. With this technology, a TSE pulse sequence is generated that includes a series of radio frequency (RF) refocusing pulses to produce a corresponding series of nuclear magnetic resonance (NMR) spin echo signals. A gradient waveform including a plurality of segments is generated. The plurality of segments collectively comprise a spiral ring retraced in-out trajectory. During an interval adjacent to each of the series of RF refocusing pulses, a first gradient pulse is generated according to the gradient waveform. The first gradient pulses encode the NMR spin echo signals. An image is then constructed from digitized samples of the NMR spin echo signals obtained based at least in part on the encoding.

Abstract: A connection arrangement for temporary shoring in an excavation site is used to secure I-beams together at corners within the excavation site. Typically, four I-beams are connected together to form a rectangular frame that is suspended within the excavation for bracing the shoring walls thereof. However, any polygonal shape may be used. The connection arrangement includes mating socket or connecting members which are placed over the ends of I-beams to be fastened together. One of the connecting members includes an outwardly extended tab while the other includes a pair of outwardly extended tabs. The first outwardly extending tab fits between the two extending tabs of the corresponding connecting member. All of the tabs are provided with apertures which are placed in alignment when the connection is made so that a bolt or pin can be passed through the apertures to secure adjacent connecting members together.

Abstract: A laminated glazing unit incorporates an electroluminescent element laminated to a transparent exterior ply. The electroluminescent element is selectively operable to generate visible light by passing current through electrodes contacting the electroluminescent material. The glazing unit can further have a solar load reduction film. One or more Fabry-Perot interference filters may serve as the electrode(s) of the electroluminescent element to provide the additional function of solar load reduction.

Abstract: A method is disclosed for producing superior optically clear laminates having a sheet of semi-rigid material encapsulated in a thermoplastic interlayer between layers of rigid material such as glass. Pre-cooled laminate elements are assembled at reduced temperature, allowing positioning of the sheet of semi-rigid material in the interlayer of the assembly with minimal wrinkling, formation of air bubbles or entrapment of moisture. Thereafter, the laminate assembly is maintained under vacuum for an extended period of time, substantially eliminating wrinkling, air bubbles and moisture from between the laminate elements as well as pre-forming the semi-rigid sheet. Bonding heat and pressure is then applied, first heating the assembly to "tack" the laminate elements together, and next applying heat and pressure for bonding the laminate elements.

Abstract: This specification is directed to a method for improving emmissivity value of a pyrolytically applied doped tin oxide film on a surface of a glass substrate, such as a sheet of glass. The method includes the steps of heating the surface of the glass substrate to an initial temperature in a range from 560.degree.-650.degree. C. and thereafter applying to the surface of the glass substrate a doped tin oxide film by a pyrolytic decomposition process. The pyrolytic decomposition process is one which cools the surface of the glass substrate. The surface of the glass substrate is reheated to a temperature equal to or greater than the initial temperature but not in excess of 675.degree. C. Thereafter, a doped tin oxide film is applied to the previously coated surface of the glass substrate. The reheating and application steps may be repeated as many times as desired to produce a coated glass substrate having the desired coating thickness and emmissivity characteristics.

Abstract: This specification is directed to a glass spandrel product which finds particular utility as a device for enclosing a building. In accordance with preferred teachings of the invention, the new product includes light-transmitting glass sheet having first and second surfaces. A tape is also provided which is attached to one of the surfaces of the light-transmitting glass sheet. The tape is formed from an organic based strip material having good elongation strength and tensile strength characteristics and an organic adhesive which bonds the strip material to the surface of the glass sheet. The organic based strip material may be of a selected color so that the glass sheet has a desired color when viewed through the surface not having the tape bonded thereto.

Abstract: This specification discloses a method of forming a decorative surface on a body of glass. The steps involved in the method are initiated by a step of forming a metallic oxide film on the surface of the body of glass to be decorated. At least the portion of the body of glass having the metallic oxide film thereon is immersed in an etchant acid bath. Thereafter the body of glass is removed from the etchant acid bath when the etchant acid bath has reacted with the metallic oxide film to create a decorative surface on the body of glass. The decorative surface includes a plurality of elongated lines generally intersecting with one another. In normal cases the metallic oxide film is a multicomponent metallic oxide film.

Abstract: A new article of manufacture is disclosed. This article includes a glass substrate having at least first and second surfaces. A coating is placed on at least a portion of one surface of the glass substrate. The coating has a thickness in a range from about 70 angstroms to about 120 angstroms. The coating consists, on a mixed metal oxide weight basis, of about 60 to 70% cobalt, 12 to 18% chromium, and 16 to 24% iron. A protective layer is placed over the coating.

Abstract: A method of applying a metallic oxide coating to a moving ribbon of glass is disclosed for four thicknesses of glass, namely, 7/32; 3/16; 5/32 and 1/8 inch. In each of these methods, first and second spray zones are established at opposite edges of the moving ribbon. The spray zones are moved in a simultaneous manner at the same speed from one edge to the other edge whereby the spray zones pass each other at the center line of the moving ribbon. When each of the spray zones reach the opposite edge of the moving ribbon, their direction of travel is reversed so that they once again pass one another at the center line of the moving ribbon. The first and second spray zones are spaced a slight distance from one another in the direction of movement of the moving ribbon. The moving spray zones are cycled back and forth in the aforedescribed manner continuously as the ribbon of material is moved thereunder so that a coating is applied to the moving ribbon.

Abstract: A training aid of the simulator type for use in teaching the techniques of adjusting the cylinders of a multi-color rotary web printing press to achieve acceptable registration between the successive impressions forming a printed color page. Four superimposed positive colored film transparencies mounted on a light box provide facsimiles of the red, yellow, blue and black images successively printed on a web; and all but the black transparency are carried separately on adjustable frames which are movable to effectively simulate the endwise (button-to-gear), the circumferential and the cocking adjustments of the plate cylinders of a rotary press. Endwise and circumferential simulating movements are by electric motors each of which is controlled for forward and reverse drive by a manual switch that is identical with the switch on a press cylinder adjustment control panel, and the manual cocking control precisely simulates that for a press cylinder.
