  • Publication number: 20240073279
    Abstract: Aspects as described herein are directed to providing an enhanced user experience for consuming content on a computing device. Secondary computing devices, such as handheld smartphones and tablet-style computers, may be identified by a primary computing device, such as a set-top box. The secondary computing devices may be configured to receive actionable instructions from the primary computing device. An actionable event associated with content being outputted to a user via the primary computing device may be determined and an actionable instruction may be transmitted to the secondary computing device in response to the determined actionable event.

  • Patent number: 7323878
    Abstract: The present invention is directed to a ground-current isolating circuit for providing a low voltage barrier between a service neutral conductor and an associated grounding system. The voltage barrier circuit comprises a first current unidirectional element and a second current unidirectional element connected in antiparallel. The unidirectional elements are preferably diodes having a characteristic threshold voltage. The current in a forward biased direction is blocked by the circuit until an applied forward biased voltage exceeds the threshold voltage. The present invention also is directed to a method of isolating a neutral conductor temporarily from an associated grounding system during testing of a structure grounding system.

  • Patent number: 7152792
    Abstract: The disclosure is for an apparatus and method for voting that are based on personal computers. All data and software, including the operating system, voting software, and original ballot information are on a single portable data storage medium, such as a diskette. During use, voting results and security-check information are added to the same portable storage medium. The apparatus also includes a tamper detectable seal for a diskette in the computer and means for officials to authorize each voter to begin voting. In one sealing system diskette removal is prevented by a blocking plate that slides into the diskette slot above the diskette and an extension fastened to the diskette is also attached to the blocking plate assuring that the diskette cannot be removed until a visible seal is broken.

  • Patent number: 5532496
    Abstract: In electron beam lithography, formation of micron and submicron size features is complicated by undesired nonuniform (pattern-density dependent) resist exposure from electrons backscattered from the underlying substrate. The disclosed technique uses a combination of a scattering mask and a scattering filter to add a leveling background exposure automatically and thus provide uniform contrast across the entire exposure pattern.

  • Patent number: 4642438
    Abstract: A high precision, high throughput submicrometer workpiece positioning system, particularly useful as a workpiece positioning means in electron beam lithography tools. The positioning system increases mechanical stability by essentially eliminating mechanical hysteresis, which allows state of the art electron beam lithography systems to provide the repeatable, accurate and dense circuit patterns that modern semiconductor trends demand.The positioning system in preferred form comprises a movable positioning table, a workpiece supporting superstructure which is elastically joined to the movable positioning table by three geometrically distinct kinematic support means and a two-stage coupling means which mounts a workpiece (i.e., semiconductor mask or wafer) to the workpiece supporting superstructure. A laser interferometer locating-positioning system is utilized to position the workpiece. The interferometer mirrors are integral with the workpiece supporting superstructure.

  • Patent number: 4293224
    Abstract: An optical system and technique for monitoring a monotonic change in the thickness of a transparent film by means of optical interference, and for eliminating ambiguity in the identification of absolute film thickness. The system is particularly adapted for monitoring the etching of a dielectric film of uncertain initial thickness in microelectronic fabrication. The technique utilizes a white light source directed upon the film. Reflected light, modified by optical interference in the dielectric film, is monitored by photodetectors at two distinct wavelengths. The cyclic patterns of intensity change at the two wavelengths are compared to identify unambiguously the absolute thickness of the film, although the initial uncertainty in film thickness may have corresponded to several cycles of either wavelength pattern alone.
