Title: Multi-display electronic devices having open and closed configurations
Inventor: ROSENTHAL EUGENE J
IPC: H04M1/02
Filed: 1998-07-29
Abstract: A portable or other electronic device has two or more display devices or screens that can be used to display different subsets of image signals. The effect is that the device simulates the display capabilities of devices having much larger screens. The device has an open or active configuration, in which the multiple screens are available for displaying image signals, and a closed or inactive configuration, in which some or all of the multiple screens are folded together or otherwise stowed away to reduce the size of the device for storage and/or carrying. By simulating large-display operations, electronic devices according to the present invention are capable of presenting more useable information to the user than is otherwise possible using prior art devices having a single small screen.

Patent CA-2268206-A1 (CA)
Title: Distillation schemes for multicomponent separations
Inventor: FIDKOWSKI ZBIGNIEW TADEUSZ
IPC: F25J3/02
Filed: 1999-04-01
Abstract: The present invention teaches an efficient and easier to operate distillation embodiment to separate mixtures containing three or more components into streams enriched in one of the components. In this invention, from one end of an earlier distillation column, a liquid or a vapor stream containing two or more components is sent to a subsequent column, then a return vapor or a liquid stream is implemented between the same locations of the two columns. This establishes a two-way communication between one end of the earlier distillation column and the subsequent distillation column. From the other end of the earlier distillation column, a vapor or a liquid stream is eventually fed to another location of the subsequent distillation column; no return stream is implemented between the same locations of the two columns. This establishes the one-way communication between the other end of the earlier distillation column and the subsequent distillation column. The superior performance of the invention resides in the fact that the earlier distillation column has a two-way communication from one end and a one-way communication from the other end with the subsequent distillation column.

Inventor: CROMER DARYL C
IPC: G06F21/00
Filed: 1999-05-12
Abstract: A system for monitoring tamper events in a computer system is disclosed. The computer system is on a network. The system comprises a tamper realtime clock (RTC) means which receives at least one tamper event signal from the computer system. The tamper RTC  includes a timer for indicating the time of a tamper event and a management device for receiving the at least one tamper event signal. The management device issues a command to the tamper RTC means to obtain the time of the at least one tamper event. The management device also generates a network packet which includes the time of the tamper event to a system administrator of the network. The present invention in a preferred embodiment is directed to a computer system which has the ability to functionally detect and store the time of a tamper event. A tamper real time clock (RTC) circuit is operatively connected with logic to store the date and time of an event as it occurs. In a preferred embodiment, the tamper event could be as simple as a toggle switch being activated when a cover on the computer system is removed. The computer system could also send network alerts when the cover is removed.
