Title: Automated, classified expenditure data card recording system
Inventor: YU MASON K
IPC: G06Q40/00
Filed: 1997-08-25
Granted: 1998-06-23
Abstract: This is an expenditure data recording system using a uniquely designed classification binary code (or its equivalent) stored within the point of sales terminal system consisting of a cash register, a credit/debit card reader, and a telecommunications line. In a sales transaction, a credit/debit card passes through this reconfigured point of sales terminal not only to furnish relevant information (date/time, vendor identification, cardholder's name and account number, and transaction amount), but also to classify the expenditure by category via instant telecommunications link upon approval by the credit/debit card issuer (financial institution). Whenever there is a needed classification change at the point of sales terminal, one utilizes a unique set of color, binary-encoded cards to redefine a new expenditure category. Whereupon the credit/debit card issuer can process this classified expenditure sales transaction information to produce a periodic financial report, and remit it to the credit/debit account holder at any time. This entire operational system is virtually transparent to the cardholder and sales personnel.

Granted: 2003-12-23
Abstract: A corner post/edge protector structure comprises an apex portion, a pair of leg members disposed substantially perpendicular with respect to each other, and concave/convex transitional regions integrally interconnecting the leg members to opposite ends of the apex portion. The concave/convex transitional regions define axially extending strengthening ribs for enhancing the axial or columnar compressive strength characteristics of the structure when the same is used in conjunction with stacks or tiers of packages, containers, or palletized loads. In addition, the transitional regions permit outer and inner surface portions of the leg members to be coplanar with outer and inner surface portions of the apex portion so as to facilitate or enable compact storage of the containers, packages, or palletized loads within cargo holds and storage facilities. Still further, the transitional regions enable the leg members to undergo resilient flexural movements under impressed packaging strapping loads or forces and facilitate favorable distribution of the strapping loads or forces.

Granted: 2006-04-04
Abstract: An electric filament incandescent in lamp, in particular a halogen incandescent lamp (9) with a rotationally symmetrical lamp bulb (10) and I.R. radiation reflecting coating (14), has an ellipsoidal partial contour. The ellipsoidal partial contour of the lamp bulb is produced by an elliptical section, the large semiaxis, and, consequently focal axis of which is oriented vertically to the longitudinal axis, i.e. vertically to the rotational axis of the lamp bulb (10). The length of the large semiaxis (a) lies preferably in the range R < a < R + 5.w r, wherein R and w r  respectively stand for the greatest radius of the lamp bulb (10) and the radius of the cylindrical luminous element (15). The lamp (9) is characterized by uniform back reflection of the I.R. radiation onto the cylindrical luminous element (15) arranged centrically on-axis inside the lamp bulb (10), and thus by a regular temperature distribution, as well as by increased lamp efficiency.

Title: Communications methods and apparatus
Inventor: TERRY JOHN BRIAN
IPC: H04L1/00
Filed: 1998-10-22
Granted: 2003-01-21
Abstract: Ethernet frames are communicated via a telephone line between master and slave modems using half duplex communication of data and control information to avoid collisions, data to be transmitted being buffered in each modem. Different communication modes, involving different transmitted symbol frequencies, modulation methods, and bits per symbol to provide different transmission rates, can be used depending on errors on the line. To reduce signal attenuation and interference both of which increase with increasing frequency, a lowest frequency communication mode is used for transmitting control information when there is no data in the buffer for transmission, whereas a higher transmission rate communication mode is used for transmission of data and control information when the buffer is not empty. The communication mode can also be adjusted in dependence upon signal to noise ratio, signal and noise energies being monitored by the modem receiver respectively during and in a quiet period immediately following each received signal burst. Changes especially to a higher transmission rate communication mode can be made selectively depending upon a monitoring in the quiet period by the modem receiver of noise in the higher communication mode, the relevant signal to noise ratio being determined from this and a stored signal level for this mode.

Patent CA-2278969-C (CA)
Inventor: WITSCHORIK CHARLES ARTHUR
IPC: H04M11/00
Filed: 1999-07-28
Granted: 2003-03-25
Abstract: An arrangement for providing secure transmission of information. The bulk of the information is transmitted over non-secure channels such as broadcast media which terminate on a plurality of receiving stations. However, a residue of data is transmitted over a protected channel, such as a point-to-point channel, established for example, by a telephone connection. Interception of a complete message, when only the bulk of the message is available, becomes very difficult. It becomes even more difficult if scrambling arrangements are used to select the particular bits of the data message that are transmitted over the secure channel. It becomes still more difficult, if the data transmitted over the secure channel, itself, alters the scrambling algorithm.

Title: Device comprising carbon nanotube field emitter structure and process for forming device
Inventor: ZHU WEI
IPC: H01J9/02
Filed: 1999-08-13
Granted: 2004-01-06
Abstract: The invention provides improved devices containing adherent carbon nanotube films, in particular electron field emitter structures containing such films. Previously, attaining even moderate adherence of powdery or mat-like nanotubes to a substrate was difficult, because of the perfect fullerene structure of nanotubes, which tend to exhibit no dangling bonds or defect sites where chemical bonding to the substrate is able to occur. The invention overcomes these problems, and provides a strongly adherent nanotube film, by a variety of fabrication processes.
