Title: Method and apparatus for multicast transmission of packet data in a mobile communication system
Inventor: LEE SUNG-WON
IPC: H04W8/26
Filed: 2003-06-02
Granted: 2011-05-10
Abstract: An apparatus and method for multicast transmission of packet data in a mobile communication system. To multicast packet data to a group of MSs, a BS  divides a plurality of MSs within its cell area into a plurality of multicast groups.  Here, the MSs of each multicast group are to receive the same data. The BS  assigns a MMAC index to each multicast group. Upon receipt of a multicast traffic channel request message from an MS, the BS transmits to the MS a traffic channel assignment message with the MMAC index of a multicast group to which the MS belongs and transmits forward packet data to the MS on a traffic channel corresponding to the MMAC index.

Title: Brake control system defined by field programable gate array
Inventor: BECK ARNOLD
IPC: B60T8/78
Filed: 2003-02-25
Granted: 2010-11-09
Abstract: A brake control system for a wheeled vehicle includes a field programmable gate array configured to perform the algorithm of brake control subsystems in a typical brake control system for a wheeled vehicle. The brake control subsystems typically include anti-skid control, brake temperature monitoring, built-in tests, and, in the case of an aircraft, nose wheel steering. The system also includes wheel speed sensors, brake temperature monitors, brake valves and associated control circuits, and brake valve monitors respecting brake valve current and voltage. The use of field programmable gate arrays to configure a brake control system avoids the obsolescence and shortened life of control systems previously dependent upon microprocessors and the like.

Title: System and method for verifying delivery and integrity of electronic messages
Inventor: TOMKOW TERRENCE A
IPC: H04L12/58
Filed: 2003-02-21
Granted: 2013-11-26
Abstract: A server receives a message from a sender and transmits the message through the Internet to a recipient. The server normally transmits the message in a first path through the Internet to the recipient. When the sender indicates at a particular position in the message that the message is registered, the server transmits the message in a second path through the Internet to the recipient. The sender can also provide additional indications in the message to have the server handle the message in other special ways not normally provided by the server. After learning from the receipt or the recipient's agent through the Internet that the message was successfully received, the server creates, and forwards to the sender, an electronic receipt. The receipt includes at least one, and preferably all: the message and any attachments, a delivery success/failure table listing the receipts, and the receipt times, of the message by the recipient's specific agents, and the failure of other agents of the recipient to receive the message and a digital signature of the message and attachments subsequently. By verifying that the digital signature on the sender's receipt matches the digital receipt at the server, the server can verify, without retaining the message, that the receipt is genuine and that the message is accurate.
