Title: Incremental backup system
Inventor: MALCOLM PETER BRYAN
IPC: G06F17/30
Filed: 1994-12-01
Abstract: In a method and system for operating a computer system, in particular a microprocessor-based computer system, modified areas of one or more files on a hard disk are monitored (22), and an auxiliary database is constructed (24) containing modification data sets relating to the location of those modified areas. On backup, the database is interrogated (30) and just those areas of files which have been modified are backed up (32) as a modification file. In this way the sue of the backup may be reduced. Subsequently data may be restored by interrogating the auxiliary data to identify which file areas are in the modification file, and selectively overwriting the data on the hard disk with backed-up data read from the modification file. The method and system may be incorporated in a dedicated backup application and/or operating system, or may interact with a conventional file-by-file backup application.

Inventor: LYNN DALE EVERETT
IPC: H04M1/72502
Filed: 1996-09-09
Abstract: Electrostatic discharge (ESD) protection for an electrical device is provided through an arrangement which detects an ESD event occurring in the device and reconfigures a processor in the device after the ESD event so that the event is essentially transparent to a user of the device. A detector circuit incorporated into the device detects the occurrence of the ESD event and, in response thereto, generates a trigger signal which is coupled to the processor. Upon receipt of this trigger signal, the processor retrieves status information that is stored in non-volatile memory and was previously contained in a program being executed just prior to the ESD event, reconfigures itself using the status information, and resumes operation with this status information. A data latch connects to the processor and buffers data from this processor to circuitry controlled by the processor. During the occurrence of the ESD event, the trigger signal is coupled to the data latch forholding the data in an output buffer in the latch. This data, generated by the processor just prior to the occurrence of the ESD event, maintains the circuitrynormally controlled by the processor in its appropriate operating state while the processor is being reconfigured.

IPC: G06Q30/06
Filed: 1995-05-05
Abstract: A system for communicating with a card distribution center (40) for selecting, ordering, and sending social expression cards (120) using a personal computer (5). The user can enter names (130) and addresses (135) of card recipients into the system wherein the information is maintained in a recipient database (90). The system displays digitized images of the cards (figures 8 and 9) on a display screen (10) which are retrieved from a card database (110). From the cards displayed, the user can select cards for designated recipients and enter personalized messages (1055) and a digitized signature (1070). The user may then send the order to a card distribution center (40), which processes the order, retrieves and prints the selected card images, including any user messages or user signature, and mails the cards to designated recipients or customers (figure 11). The system maintains a database of all recipients (130), addresses (135), associated occasions and dates (100), card preferences (145), relationships (111, 112) and order history (105).

Title: Vibrator
Inventor: BUDAEV JURY ALEXEEVICH
IPC: B06B1/18
Filed: 1996-12-12
Abstract: A vibrator is proposed with an exhaust chamber in a baseplate thereof. The exhaust chamber is limited by walls of the baseplate, second bushing and the outer surface of a hollow elastic element and is in communication with an above-membrane chamber via a second duct. The elastic element is a truncated hollow cone, the smaller base of which firmly encompasses the second bushing, while the larger base bears against the baseplate. A first duct communicating the above-membrane chamber with the atmosphere is formed by radial ducts in the cover of the baseplate, in which an annular collector is made, communicating with said radial ducts. The flow area of each of the ducts is less than the flow area of the collector. The latter by means of coaxial axial ducts made in the cover and in the baseplate communicates with a second annular collector made in the baseplate and communicating with the atmosphere.
