Abstract: The invention relates to a variable focus lens (10), comprising a rigid ring (22), a flexible membrane (20) attached to the front surface of the ring, a rigid transparent front cover (40), attached to the flexible membrane (50), and a rigid rear cover (20) on the rear surface of the ring (22). A cavity (60) is formed between the flexible membrane (50) and the rear cover (20), and the cavity is filled with a liquid. The amount of liquid in the cavity can be varied to vary the curvature of the flexible membrane and so vary the optical characteristics of the lens. The rear cover can be integral with the ring, or formed separately. Further, a second flexible membrane can be positioned between the rear cover and the ring. The various parts of the lens can be held together by adhesive.

Abstract: Embodiments of the invention provide systems and methods for validating ownership of a domain name. According to one embodiment, a validating ownership of a domain name can comprise retrieving one or more domain name ownership records. For example, the one or more domain name ownership records comprise Who Is records. Validity of the one or more domain name records can be confirmed with a designated domain manager. According to one embodiment, confirming validity of the one or more domain name records with the designated domain manager can comprise authenticating the designated domain manager based on a certificate provided by the designated domain manager.

Abstract: The invention provides a variable focus lens, comprising a ring with a front surface and a rear surface. A flexible membrane is held between the front surface of the ring and a generally rigid transparent front cover, and a rear cover is attached to the rear surface of the ring (optionally with a second flexible membrane sandwiched between the rear cover and the ring). A cavity is formed between the flexible membrane and the rear cover (or the second flexible membrane) is filled with a liquid, and the amount of fluid in the cavity can be varied to vary the curvature of the flexible membrane and so vary the optical characteristics of the lens. The ring of the lens may be coloured, and may be transparent, translucent or opaque. Alternatively, a decorative cover may be attached to the front of the ring to give the appearance of a frame. The lenses may be used in variable focus spectacles.

Abstract: A variable focus lens (10) comprises a ring (20) with a front surface and a rear surface. A flexible membrane (40) is held between the front surface of the ring and a generally rigid transparent front cover (50), and a rear cover (60) is mounted on the rear surface of the ring, such that a cavity formed between the flexible membrane and the rear cover can be filled with a liquid. The amount of fluid in the cavity can be varied to vary the curvature of the flexible membrane and so vary the optical characteristics of the lens. The ring is provided with an integral hollow extension (22), whose hollow interior (24) communicates with the cavity and forms a liquid reservoir for the variable focus lens (10). The invention also extends to spectacles using the lens.

Abstract: Variable focus optical devices, in particular lenses, can include a cavity at least partially defined by a flexible member (2), which may be retained between engaging portions of a frame member (8) and a ring member (12), such that a peripheral region of the membrane is caused to change direction, more than twice. The engaging portions of the ring and frame may be high-friction surfaces. In addition, methods of filling a cavity of a lens with transparent fluid, methods of adjusting the pressure of fluid in the cavity, and methods of sealing such a cavity are described, as well the use of such lenses in adjustable spectacles.

Abstract: Tools and techniques for identifying brand misuse and/or for distributing information about such misuse. Certain of the tools and techniques can be used to determine that a set of online content (e.g., a web site, web page, or portion thereof) is untrustworthy (for example, because that set of online content misuses a brand) and generate a brand notification feed indicating the untrustworthiness of the set of online content. This brand notification feed might be distributed to a security vendor, who can incorporate information from the brand notification feed into the information it provides to clients.

Abstract: A threaded fastener having a two-piece nut member and a bolt with the nut member having a threaded nut member and a base member is disclosed. The threaded nut member has a body portion and a neck portion, the neck portion engaging with a transition beginning engagement on the base member. The base member includes a transition portion, the diameter of the transition portion increasing radially as it extends axially from the cylindrical through bore portion to an increased diameter at the outer planar surface of the base member. Movement of the neck potion into the based member results in the threaded form having a compressive engagement with engaged threads of the bolt to provide the prevailing torque structure. The threaded nut member and base member may be made of dissimilar materials and is more flexible in use with varying bearing surfaces.

According to another embodiment, reputation information related to the website can be requested from a reputation service. The reputation information can comprise a score indicating the relative authenticity of the brand information used by the website. The reputation information can be received from the reputation service and an indication of the authenticity of the brand information used by the website can be generated based on the score.

Abstract: Well data and production control commands are transmitted from a remote central data store to wells at a remote location with a well hopping system and method, preferably through a radio frequency (RF) network. Request packets are sent through a field station to one or more well units until it reaches the destination well unit. The destination well unit executes the data request or the command and sends a response data packet back to the central data store through the RF network using the same well hopping system and through the field station. The central data store reads and stores the data. One or more satellite offices are connected to the central data store and can download data from the central data store or send/receive data packets to/from the well units. Oxygen content in production gas can be detected and transmitted to the central store for monitoring and reporting.

Abstract: A light source is situated on a headgear device and placed to direct light toward the pupil of the eye at an intensity that causes the iris to constrict, resulting in a smaller pupil. This prevents the light scattering due to ophthalmic surgery or eye injury from entering the eye, thereby reducing or eliminating visual aberrations.

Abstract: Request packets are transmitted from a central location to remote wells through a wireless well hopping path. A destination well unit executes a data request or a command and sends a response data packet back to the central location through the same wireless well hopping path. One or more satellite offices are connected to the central location and can download data from the central location or send/receive data packets to/from the well units. Oxygen content in production gas can be detected and transmitted to the central location for monitoring and reporting. Multiple data requests can be made in a single request packet.

Several embodiments are directed to logically reconciling conflicting metadata between two or more metadata components related to read or write operations of said metadata by applications or devices. Several other embodiments are directed to proactively finding conflicts in metadata components of a file and proactively reconciling them for present and future utilization of said file.

Abstract: A system and method for capturing, displaying, and navigating text annotations in a non-modifiable document is disclosed. Once it is determined that a text annotation is to be created, the system determines the file position of the selected object. The file position of the selected object is stored along with the created text annotation in another file or a non-read only portion of a file storing the document. Using the file position, the text annotation may be properly identified with the selected object without modifying the non-modifiable document. Once a text annotation is displayed a user may easily navigate among the captured annotations.
