Patent CA-2267735-A1 (CA)
Inventor: MOODY EUGENE I
IPC: A01F25/00
Filed: 1999-03-30
Abstract: A grain drying apparatus uses the heat of an engine to aid in the evaporative process. The grain drying apparatus provides an engine 20 which is used to power a fan 40. Waste heat generated by the engine is transferred to air driven by fan 40 through air duct 70 by three principle means. Air is initially warmed by contact with the engine and its radiator prior to entering the air duct 60. An exhaust pipe 50 and catalytic converter 52, carried by the engine, extends a part of the length of the elongated air duct 70, warming the air flow within the duct by contact. A finned heat exchanger tube 60, also carried within the elongated air duct, transfers heat to the air flow within the duct. An air intake pipe transfers air under pressure into a fuel tank, where the air mixes with fuel vapors. The air and fuel vapor mix is then transferred to the exhaust pipe, where combustion takes place, thereby increasing the heat flow from the finned heat exchanger. Cooled exhaust gas from the finned heat exchanger tube 60 is optionally routed through a dehydration canister and into the grain storage area where the treated exhaust gases displace the air, providing an atmosphere which protects the grain from bacteria, insects and rodents.

Filed: 1998-12-07
Abstract: Cette invention concerne un dispositif qui permet de coder un train de bits de données d'un signal source binaire (S) en un train de bits de données d'un signal canal binaire (C). Le train de données du signal source est divisé en mots source de n bits (x¿1?, x¿2?). Ce dispositif comprend des systèmes de conversion (CM) qui vont convertir les mots source en mots canal correspondants de m bits (y¿1?, y¿2?, y¿3?). Les systèmes de conversion (CM) permettent en outre de convertir des mots source de n bits en des mots canal correspondants de m bits de sorte que la conversion pour chaque mot source de n bit assure un maintien de la parité (tableau I)(Fig. 1). A cette fin, les relations suivantes doivent être respectées: m > n?1 et p?1, étant entendu que p peut varier et que, de préférence, m = n + 1. Ce dispositif va convertir la séquence binaire de 8 bits "00010001" du signal source en une séquence binaire de 12 bits "100010010010", et convertir la séquence binaire de 8 bits "10010001" en une séquence binaire de 12 bits "000010010010", ceci de manière à limiter la longueur de plage de transition minimale répétée dans le signal canal. Les autres séquences de 8 bits nécessitent en outre un codage spécifique pour obtenir des séquences de 12 bits, ceci afin de limiter la contrainte k du signal canal à 7. Cette invention concerne également un dispositif de décodage qui permet de décoder le signal canal obtenu à l'aide du dispositif de codage.

Patent CA-2292224-A1 (CA)
Title: Method and apparatus for developing event driven software
Inventor: THOMPSON KENNETH LANE
IPC: G06F9/44
Filed: 1999-12-15
Abstract: A programming technique for defining, structuring, and developing event driven software. More particularly, event driven software is structured in two basic parts: control-sensitive code and non-control-sensitive code. Control sensitive code includes the identification of control states, the events that are generated and that must be recognized, and the responses to the arrival of particular events in particular states. Further, within the control-sensitive code defining the system, control states are uniquely identified throughout such program code with a single symbol. The non-control-sensitive code, specified separately from the control sensitive code, is directed at the necessary normal sequential code for programming the event driven system such as the invocation of device drivers, the control of peripheral devices, the updating of tables, variable definition, etc. Advantageously, the technique allows the software developer to structure the event driven software application source code such that a clear distinction is made between core control features, i.e., states, events and responses, and extraneous details not directly impacting the behavior of the event driven system. As such, the programmer can readily determine the exact execution flow from control state-to-control state directly from a cursory examination of the program code itself as the individual control states have a strong visual context.

Title: Method and system for determining the position of mobile radio terminals
Inventor: BERG JAN-ERIK
IPC: G01S5/14
Filed: 1998-08-18
Abstract: The disclosure describes a novel Time Difference of Arrival (TDOA) method and system for determining the position of a first mobile radio terminal within an associated mobile radio system, which is based on Time of Arrival (TOA) measurements, including a plurality of radio base stations, measuring devices, network controller, and service node. The measuring devices are synchronized in otherwise unsynchronized radio base stations. The measuring devices measure TOA on demand and (optionally) Direction of Arrival (DOA), on a digital uplink time slot or on digital information on an analog uplink traffic channel in one or more radio base stations. The TOA and DOA information and the traffic channel number are reported to a Mobile Services Switching Center, which obtains the first mobile terminal's identity from the traffic channel number and sends the terminal identity and TOA and DOA measurement information to a Service Node. The Service Node calculates the position of the first mobile radio terminal using the TOA information (supplemented by the DOA information when available). A second mobile radio terminal is colocated on a mobile platform (auto, emergency vehicle, etc.) with one of the radio base stations, which can be moved into relatively close proximity with the first mobile radio terminal. Consequently, by moving one of the radio base stations close to the region of interest (near the first mobile radio terminal), the position determination accuracy is significantly improved.
