Patent CA-2178938-A1 (CA)
Inventor: DAVIS GEORGE B
IPC: F24F12/00

Abstract: An energy recovery ventilator (ERV) for exchanging indoor air with outdoor air. The ERV (1) having a housing including first, and second input ports (11, 12) and, first and second exhaust ports (13, 14), and a heat exchanger core (60). The ERV (1) further having a first blower (22) for drawing indoor air into the ERV (1), through the first input port (11), through the heat exchanger core (60) and out the first exhaust port (13), and a second blower (21) for drawing outdoor air into the ERV (1), through the second input port (12), through the heat exchanger core (60) and out the second exhaust port (14). A means for defrosting the ERV (1) is taught having a first bypass (48) from the first exhaust port (13) to the first input port (11) and second bypass from the second exhaust port (14) to the second input port (12). Dampers (42, 43) close the first exhaust port (13) and the second exhaust port (14) when defrost of the heat exchanger core (60) is needed. To defrost the heat exchanger core (60), the dampers (42, 43) close, closing the first and second exhaust ports (13, 14), air passes through the bypasses and recirculates through the heat exchanger core (60), upon the heat exchanger core (60) being defrosted the dampers (42, 43) open. While defrosting the blowers (21, 22) are set to high speed to increase the waste heat from the blower motors and to increase air circulation. A re-humidifier (51) is incorporated to transfer the moisture to the dry outside air being provided to the building. As the heat exchanger core (60) is defrosted, moisture from the heat exchanger core (60) is collected by the re-humidifier (51), the re-humidifier (51) converts the moisture to steam and provides the steam to the second input port (12).

Filed: 1995-10-16
Abstract: La présente invention concerne un prédicteur à horizon variable ou "VHP" (Variable Horizon Predictor) permettant de compenser, dans les boucles de commande de processus, les temps morts, les perturbations mesurées, et la dynamique de glissement temporel. Le VHP est constitué d'un modèle de processus, d'un module vectoriel de prédiction brute, d'un module vectoriel de prédiction affinée et d'un sélecteur d'horizon (54). Ayant délivré au modèle de processus un signal de sortie régulateur permettant de former un vecteur de prédiction stocké au niveau du module vectoriel de prédiction brute, le VHP fait la prédiction du signal de sortie de processus pour un horizon de prédiction. Le module vectoriel de prédiction compare au signal de sortie de processus le vecteur de prédiction puis affine la prédiction. Le vecteur de prédiction affinée est alors stocké au niveau du module vectoriel de prédiction affinée. Le sélecteur d'horizon isole une partie du vecteur de prédiction pour constituer un sous-vecteur et fournit à un calculateur d'erreur vectoriel ce sous-vecteur sous forme d'un signal d'erreur délivré au régulateur. La mise en oeuvre d'un système de régulation interactif à variables multiples se fait par couplage entre d'une part une pluralité de VHP et une pluralité de compensateurs d'interactions inter-boucle et d'autre part un processus présentant une pluralité d'entrées de régulation et une pluralité de sorties de régulation.
Patent CA-2204946-A1 (CA)
Inventor: FLORES AARON G
IPC: E21B47/01
Filed: 1997-05-09
Abstract: An apparatus and method are disclosed for actively cooling instrumentation, in particular electronic circuits, in especially, high temperature environment. This apparatus has a tank containing a cooling agent, a heat exchanger to transfer heat from the instrumentation to the cooling agent, a compressor and a tank to hold cooling agent removed from the first tank. In this operation, the cooling agent tank is located in close proximity to the instrumentation. As the instruments generate heat, the heat is transferred through the heat exchanger to the cooling agent. The cooling agent boils and vaporizes from the heat and is pumped out of the tank by a compressor. As the cooling agent vaporizes and is pumped out of the tank, heat contained in the cooling agent is transferred out of the tank as well. The rate at which the vapor is pumped out of the tank controls the temperature of the cooling agent in the tank. The vapor is compressed under pressure and pumped to a storage tank where the vapor condensesback to a liquid.

Abstract: The invention concerns a method and device for removing ticks from humans and animals. The device comprises: a base part (1) with at least one opening (2a, 2b), a thread loop (6) of resilient material which is arranged to be drawn into the opening (2a, 2b) under the effect of a spring member (5). The cross section of this opening relative to the thread loop (6) is such that the loop (6) outside the opening (2a, 2b), whilst being drawn thereinto, gradually decreases in size. Operatively connected to the thread loop (6) is a member (4, 4a) arranged such that, against the effect of the spring member (5), it shoots the thread loop (6) out of the opening (2a, 2b). According to the method of the invention, owing to pressure being exerted on the pushbutton (4a), the loop (6) is ejected from the opening (2a, 2b), laid around the tick and, since pressure is no longer exerted on the pushbutton (4a), can be drawn into the opening (2a, 2b). The loop (6) is then rotated one turn and the tick releases its grip within approximately three seconds.

Filed: 1996-07-26
Abstract: A method and apparatus for generating cryptographic keys for use in a cryptographic system includes a key generator for generating a subset of reduced key space keys from a larger B-bit cryptographic key. The subset of keys is distributed randomly over a B-bit key space according to a secret hash or distribution key to provide cryptographic keys with a larger apparent work factor. The work factor depends on the number of possible different keys for a given key bit length, and provides a corresponding level of decoding difficulty to a hostile attacker. Without knowledge of the secret hashing key, the work factor of the cryptographic key appears to be up to S=2B, and an attacker must make up to 2B guesses to determine a specific key with certainty. This level of difficulty will typically be too computationally intense for the attacker to break the system. However, with knowledge of the secret hashing key, the work factor is significantly lower. Thus, the work factor of the key can be reduced to a level which is small engough to satisfy governmental export or import requirements without reducing the protection level or strength of the system. A single cryptographic key generator (engine) can be easily adapted for use in different countries, where different work factors are required.
