Abstract: L'invention concerne un système de formation d'images faciales tridimensionnelles (3-D), le système permettant de générer des images faciales, de répertorier ces images au moyen de codes composites et de chercher des images faciales bidimensionnelles (2-D) similaires. On génère les images tridimensionnelles de visages humains à partir d'une banque de données de formes superficielles de caractéristiques faciales tridimensionnelles. Ces formes sont organisées en parties de caractéristiques faciales. En assemblant une forme pour chaque partie faciale, on forme une image faciale tridimensionnelle. On peut représenter des images faciales humaines avec un code composite (code de partie de caractéristique faciale et code de forme). On peut générer une image tridimensionnelle de n'importe quel visage en utilisant le code pour sélectionner les formes de caractéristiques faciales appropriées dans la banque de formes en mémoire.

Title: Aircraft air-conditioning apparatus with water separators
Inventor: MUELLER WOLFGANG
IPC: B64D13/06
Filed: 2000-08-03
Abstract: A system for air-conditioning the cabin of a passenger aircraft using externally provided fresh air as well as bleed air tapped from the engine of the aircraft includes at least one heat exchanger, a blower, a compressor, an expansion turbine, a condenser, a reheater, a first high pressure water separator, and a second low pressure water separator. The several components are connected to each other by air lines such as air ducts, with control valves interposed therein. Two separate air-flow paths representing two different sub-systems are formed. A first air--flow path uses the high pressure water separator while a second air-flow path uses the low pressure water separator. These two air-flow paths or sub-systems can be operated separately and independently of each other by appropriately switching respective shut-off valves. In this manner, the operation of the air--conditioning system can be adaptively switched to achieve an optimal operation under different operating conditions of the aircraft and different air-conditioning requirements.

Title: Method and apparatus for suppression of packets during silence periods in a packet telephony system
Inventor: LAM YUK-MING PETER
IPC: H04W88/18
Filed: 2000-10-23
Abstract: A method and apparatus are disclosed for notifying a far-end calling party when a near-end calling party utilizes a hold or mute feature. The present invention reduces bandwidth utilization by suppressing the transmission of packets during periods of extended silence. Each packet telephony device includes a packet suppression system that monitors local terminal activity and notifies the far-end party that the near-end device is discarding the "listen" stream. In addition, the disclosed packet suppression system monitors the incoming packets and processes such notifications from the far-end party that the far-end device is discarding the "listen" stream. In response, the packet suppression system can suppress the transmission of further packets and optionally activate a music-on-hold feature for the held party.

Patent CA-2332168-A1 (CA)
Inventor: CHAMPION MARK
IPC: F24B1/02
Filed: 2001-01-24
Abstract: A combustion system for burning firewood including a combustion chamber defined by front, rear and side walls, a ceiling and a bottom. An access door is provided for addition of fuel into the combustion chamber. A substantial amount of combustion air enters the combustion chamber near the top of the fueling doors via apertures and is directed down the face of the fueling doors providing cooling. A geometry of the air metering orifice is either fixed or of limited adjustability such that the minimum flow of combustion air required for flaming combustion of a full load of fuel is maintained at all times. The combustion air flow cannot be reduced beyond a certain point and thus smoldering and very low air/fuel ratios are avoided. Since the air metering is tuned for proper flaming combustion with the largest expected fuel load and cannot be reduced further, fuel loads smaller than the design fuel load will result in higher air/fuel ratios, thus further ensuring that sufficient combustion air is present for sustained flaming. Furthermore, the minimum combustion air setting limits the amount of combustion air entering the combustion chamber such that too much air is not introduced resulting in inefficiency due to sensible heat loss, chemical loss (pollution), quenching of the flames, and undesirably high burn rates. Ideally, the burning rate of a full load of fuel is below 5 kg/hr, however, the maximum burn rate when burning a full load of fuel may be reduced to as low as 2 kg/hr depending on the size of the firebox and the desired maximum heating capacity of the appliance. Heat output is adjustable primarily by the amount of fuel added at each fuel loading.

Filed: 2001-05-10
Abstract: The invention relates to a process for producing an accumulator composite for accumulating heat or cold from a matrix of compressed, expanded graphite and phase change material (PCM) which is introduced into this matrix, by vacuum impregnation of the matrix with the PCM, in which process the matrix, under atmospheric pressure and partially or completely immersed in a molten PCM or a salt solution, is fixed inside an impregnation vessel, and the impregnation vessel is then evacuated until the desired degree of loading of the matrix with the PCM has been achieved.      This process provides, in a simple and inexpensive way, accumulator composites with a high degree of PCM loading and a correspondingly high energy density, excellent thermal conductivity and, on account of a residual porosity of 5%, high elasticity and stability.
