Abstract: In an environment of competitive local and interexchange carriers, offering number portability between local earners serving a common region and between switches serving that region, each local carrier accesses a regional database to determine the identity of the carrier and switch serving a local customer.  In addition, interexchange carriers access a national database to determine the identity of the carrier and switch serving the customer specified by the number dialed by an originating customer. For customers requiring high reliability service, alternate carriers can be used to serve such customers in case the primary carrier is unavailable; the databases identify these alternate carriers. Advantageously, this arrangement allows a high degree of freedom of movement of customers between carriers and geographic relocation without requiring a number change.

Title: A mechanism for secure tendering in an open electronic network
Inventor: KOU WEIDONG
IPC: G06Q30/00
Filed: 1998-05-12
Granted: 2001-02-06
Abstract: A mechanism for securing bid proposals until close of tendering is provided for an electronic tendering system over an open network. In order to be permitted to file a bid electronically in response to an invitation to tender, prospective vendors encrypt their bid proposals using session keys obtained from a third party source. The encrypted proposals are filed with the bid requester who does not have access to the session keys while the tendering period remains open. The encrypted bid proposals are cached in a safe repository until close of tendering. In one embodiment, the bid requester itself holds onto the encrypted proposals, and obtains the session keys for accessing their contents from the third party on expiry of the bid submission period. In another embodiment, the bid requester double-encrypts each encrypted bid proposal as it is received using its own privately-held key, and forwards the double-encrypted proposals to the third party to hold in a safe repository until the close of tendering. The third party then returns the double-encrypted proposals to the bid requester along with the session keys to permit the bid requester to access their contents. In either case, the party that caches the bid proposals until the close of tendering does not have access to the key required to decrypt the proposals.

Abstract: One or more players build a collapsible tower from individual bricks. At least two types of bricks are used to build the tower, with the two types of bricks (for example square bricks and rectangular bricks) having different physical characteristics which interact to affect the stability of the tower and/or the ease with which a particular brick can be removed. Each layer of the tower may be formed from bricks having possibly similar physical properties, but with at least two adjacent layers of the tower being formed from different shapes, sizes and/or numbers of bricks. The different physical properties may also include weight, surface configuration and/or coefficient of friction, thereby rendering it easier or more difficult to remove certain types of bricks having a particular spatial relationship in the tower with respect to other types of bricks. Two or more types of tower building bricks may be packaged as a self-contained tower building game, or a set of non-rectangular bricks may be used to supplement an existing set of conventional rectangular tower-building bricks, thereby providing enhanced play appeal at a minimal expense. The tower of bricks may be built on a revolving turntable to enhance each player's access to all sides of the tower and/or to limit the time for each player to make his move, and the turntable is preferably provided with a level to provide a level base for the construction of the tower.

Title: Display techniques for three dimensional virtual reality
Inventor: ENSOR JAMES ROBERT
IPC: G06T15/10
Filed: 1998-06-30
Granted: 2005-08-16
Abstract: A limitation of a three-dimensional world in which objects in the distance may be represented in only two dimensions as a video on a screen occurs when a computer graphic object represented by computer graphics, e.g., in front of, to the side, above, or below the video screen, undergoes a trajectory that takes it to a location in the world that is not represented as computer graphics, but instead is within the field represented by the video, because such an object would disappear from view by the viewer. This limitation is overcome by having such an object be represented as video on the screen, rather than computer graphics. Thus, the computer graphics object "goes into the video" as video and remains visible to a viewer in front of the video screen, rather than becoming invisible because it is blocked from view by the video screen if it were to be generated at its proper location using computer graphic techniques.

Abstract: A system for remote meter viewing and reporting. The system comprises a remote camera located at the meter. The remote camera is coupled to a central computer through a communications channel. In response to a command from the central computer, the camera scans the meter face, i.e. readings on the dials, and stores an image in memory. The scanned image is transmitted to the central computer. The central computer includes software for analyzing the scanned image in determining the consumption of electricity, for example, by comparing the current readings on the dials with the readings on the dials taken at the last billing cycle. The processed image is then used to generate a billing statement which is sent to the household consumer using conventional post. In another aspect, the billing statement generated by the system includes scanned images of the past and current meter readings. The system according to the present invention is suitable for public utilities, such as gas, electricity, water companies and leasing companies which lease office equipment to companies situated in remote locations, which equipment is fitted with meters which record their use, i.e. copying machines, printers, etc. where it is desirable to determine the quantities of copies made, thus enabling the timely scheduling of visits of company service representatives to perform ongoing maintenance, thereby helping to ensure minimal down-time and optimal equipment performance.
