Abstract: The present duel-scope colonoscopy system has a primary or parent colonoscope substantially typical of the field, but adapted to incorporate a separate, extended reach secondary or auxiliary colonoscope tool. The insertion tube of the secondary colonoscope tool is received in a tool channel of the parent scope, and is “extended reach” in that the secondary insertion tube is extendable from the tip of the primary insertion tube of the parent scope an additional distance beyond the reach of the primary scope tube. The secondary colonoscope tool is a separate and complete image viewing fiberoptic colonoscope having a flexible, small diameter fiberoptic cable insertion tube of a length sufficient to substantially extend beyond a distal end the insertion tube of the parent endoscope.

Abstract: The invention includes linkage assemblies comprising coupled links with metallic contact surfaces with improved stiffness. The inventors found significant mechanical problems with all previous descriptions of metallic contact links sufficient to preclude their commercial use. These metallic contact links are a significant improvement over existing plastic ball and metal joint, or all plastic beads as found in the prior art. The invention includes methods providing these links and high friction couplings between them, as well as the linkage assemblies and flexible arms resulting from these processes.

Abstract: The present optical image viewing fiberoptic otoscope electromagnetically passive. A body portion is connectable to a light source and has mounted to it a fiberoptic cable and an optical viewer. The fiberoptic cable is thin and flexible, and contains separate light and image transmission paths. Its distal end is adapted for emitting and receiving light. The body includes a light source connection for interfacing an external light source. An optical-type image viewer attached to the body is in light communication with the image path for displaying a received image for viewing by a user. One or more tools are mountable to the otoscope body or fiberoptic cable for performing an operation at the distal end of the fiberoptic cable, e.g., removal of a material from the site. Optionally, the otoscope body may be mounted to a headband via an articulated support arm.

Abstract: Initially, a key range variable is created by concatenating the card group value, card number and reference number for an encryption key to be generated. A hashing algorithm generates an encryption key from a master key and the variable key range variable. The encryption key and the key range variable are output to the caller who requested the key. The encryption key is used to encrypt the information, while the variable key range is stored with the encrypted data. Generation of a decryption key requires a user call for a decryption key and includes the key range variable from the encrypted data. A hashing algorithm generates a decryption key from the master key and the key range variable. The decryption key is used to decrypt the information.

Abstract: An Internet-based purchasing system and associated method, including: (i) a remote terminal for use by a consumer; (ii) an on-line purchasing system, wherein the system further includes a system database in communication with the remote terminal for storing both consumer information and ticket and merchandise information; (iii) a user interface between the remote terminal and the on-line purchasing system for allowing the exchange of information and commands between the remote terminal and the on-line purchasing system; (iv) at least one source system in communication with the on-line purchasing system for allowing vendors of tickets or merchandise to sell items on-line, wherein the source system further includes a source database for storing current ticket and merchandise information; (v) a communication interface between the on-line purchasing system and the source system for allowing data exchange between the systems; (vi) software means for allowing the on-line purchasing system to monitor the source syst

Abstract: An apparatus and method for reconstructing missing data using cross-parity stripes on a storage medium is provided. The apparatus and method may operate on data symbols having sizes greater than a data bit. The apparatus and method makes use of a plurality of parity stripes for reconstructing missing data stripes. The parity symbol values in the parity stripes are used as a basis for determining the value of the missing data symbol in a data stripe. A correction matrix is shifted along the data stripes, correcting missing data symbols as it is shifted. The correction is performed from the outside data stripes towards the inner data stripes to thereby use previously reconstructed data symbols to reconstruct other missing data symbols.

Abstract: An apparatus and method for writing and reading data to and from a virtual volume of redundant storage devices is provided. The apparatus and method make use of metadata identifying the number of data storage devices and number of parity storage devices in the virtual volume of redundant storage devices. In addition, other metadata, such as the identity of the data storage devices and parity storage devices may be utilized. The metadata is stored with each block written to each of the storage devices. In the event of a failure of a storage device, the metadata is modified to reflect the failure and the storage device to which the data intended for the failed storage device was written. In this way, if a failure of a storage device is encountered, each block in the virtual volume of redundant storage devices has enough information in the metadata to identify where to find the data that was intended for the failed storage device. Thus, reconstruction of data using parity information is not required.

Abstract: The invention provides a method and a system that allow users to purchase goods and health-related services over a distributed network, like the Internet. Using a portal or a buyer interface, a user connects to a controller or server through a distributed network either directly or via a service provider. When the user connects to the controller, the controller initiates a validation sequence to identify the portal and the user. When the portal and the user are identified, the controller assigns an access code that defines the user's access rights to the controller. The user can then access fitness, nutrition, and wellness information or purchase goods from the controller, which in one embodiment emulates a web site, or provide access to other linked sites. In addition, the method and system provides users with opportunities to engage in on-line conversations with fitness instructors, coaches, doctors, and others that may be on-line.
