Title: Data detection for a hierarchical coded data transmission
Inventor: KHANDEKAR AAMOD
IPC: H04L27/38
Filed: 2004-12-08
Abstract: Techniques for performing data detection for a hierarchical coded data transmission are described. In one data detection scheme, log-likelihood ratios (LLRs) for code bits of a first data stream are initially derived based on received symbols for the data transmission. The LLRs for the first data stream are decoded to obtain decoded data, which is re-encoded and remodulated to obtain remodulated symbols. Interference due to the first data stream is estimated based on the remodulated symbols. LLRs for code bits of a second data stream are derived based on the LLRs for the code bits of the first data stream and the estimated interference. The LLRs for the first data stream may be derived from the received symbols in real-time without buffering the received symbols. The LLRs for the second data stream may be derived after the first data stream has been decoded.
Patent CA-2556842-A1 (CA)
Title: Controlling transactions
Inventor: GLASSFORD ROBERT JOHN
IPC: G06Q10/00
Filed: 2005-03-07
Abstract: Before a transaction takes place between a plurality of agent-based devices (21-29), not all of which have previous experience of each other, a data file is created which identifies all the agents which are to take part in the transaction. The data file is circulated to all the agents, and each agent endorses the data file in respect of each other agent with a positive, negative, or conditional endorsement, based on stored data indicating whether that agent is capable of co-operation with the other agent. A negative endorsement is applied by an agent in respect of any agent with which it is not prepared to co-operate. Such a negative endorsement is fatal to the transaction. A positive endorsement is applied by an agent (21) in respect of any other agent (27) with which it is unconditionally prepared to co-operate.  A conditional endorsement by a first agent (21) of a second agent (23) is applied where the first agent (21) has insufficient data to apply either a positive or negative endorsement, and expresses conditions which would allow the endorsement to be made positive - for example positive endorsement by some other specified agent (28). If these conditions are subsequently satisfied, the endorsement is amended to positive. When all agents (29) have endorsed the data file, if all the resulting endorsements are positive a successful validation is reported to the originating agent (20), allowing the transaction to proceed.

Title: Flat type seed meter disk with protruded pick up orifices
Inventor: MARIMAN NATHAN ALBERT
IPC: A01C7/14
Filed: 2006-11-03
Abstract: A flat seed disk is provided with a series of circumferentially arranged seed retaining protrusions providing seed retention at locations offset axially from the remainder of the disk. The offset allows the seed to fall in the correct location of the seed tube to reduce unwanted seed bounce and provide better seed delivery to the ground and better seed spacing as compared to flat disks without the offset.  In one embodiment, the protrusions have seed retaining faces opening generally in the direction of disk rotation. In other embodiments, the faces are angled away from the direction of rotation to reduce interference between released seed and adjacent protrusions, and trailing radial ledges can be provided to enhance seed retention.
