Title: Method and system for hard handoff in a broadcast communication system
Inventor: LEUNG NIKOLAI K N
IPC: H04H20/00
Filed: 2002-10-23
Abstract: A method and system for a handoff in a broadcast communication system is disclosed. A subscriber-assisted handoff is impractical in a broadcast communication system due to e.g., a high signaling load, a difficulty to synchronize the broadcast transmission. On the other hand, the small number of broadcast channels enables the subscriber station to perform the handoff autonomously. While performing a handoff between broadcast transmissions, a disruption of service occurs due to lack of synchronization among the broadcast transmissions. To reduce the service disruption, upon detecting a need for handoff, the lower layers inform the application layer about the forthcoming handoff. The application layer thus may take measures to reduce or prevent the disruption.

IPC: H01L33/00
Filed: 2002-10-10
Abstract: A method for forming an ohmic contact to silicon carbide for a semiconductor device comprises implanting impurity atoms into a surface of a silicon carbide substrate thereby forming a layer on the silicon carbide substrate having an increased concentration of impurity atoms, annealing the implanted silicon carbide substrate, and depositing a layer of metal on the implanted surface of the silicon carbide. The metal forms an ohmic contact "as deposited" on the silicon carbide substrate without the need for a post-deposition anneal step.

Inventor: WEBER ANTON
IPC: G06F11/16
Filed: 2003-08-01
Abstract: Processor boards that are very identically structured and that work in lockstep operation are provided for redundant systems. The basic condition for implementing a lockstep system is the deterministic behavior of all the components included in the board, i.e. the CPUs, the chipsets, the main memory, etc. In this context, deterministic behavior means that in the absence of errors said components supply identical results at identical intervals when said components receive identical stimuli at identical intervals.  Deterministic behavior also presupposes the utilization of clock synchronous interfaces. Asynchronous interfaces cause a certain temporal fuzziness in the system on many occasions, as a result of which the overall clock synchronous behavior of the system cannot be maintained. In order to nevertheless be able to carry out a lockstep operation, the invention provides a method which, unlike known software solutions, is realized in hardware for the synchronization of identical or different redundant processing units (PRO0, PRO1) which process identical instruction sequences and are clocked synchronously or asynchronously. According to said method, active transactions outside the processing units (PRO0, PRO1) are used by the blocks (EQ0, EQ1) assigned by the processing units (PRO0, PRO1) for the synchronization of the processing units (PRO0, PRO1), wherein the processing units are delayed by assigned blocks until the instruction execution of all processing units has reached the current transaction.
