Patent CA-2234498-C (CA)
Inventor: ISHIKAWA YOHEI
IPC: H01Q13/24
Filed: 1998-04-09
Granted: 2001-03-27
Abstract: The invention provides an antenna in which a signal is directly transferred from a planar dielectric transmission line to a primary radiator without having to perform transmission mode conversion from the planar dielectric transmission mode to another mode such as a coplaner transmission mode, a mictrostrip transmission mode, or a waveguide transmission mode thereby eliminating the transmission loss which would otherwise occur due to the transmission mode conversion. A dielectric resonator is disposed in the vicinity of the end of the planar dielectric transmission line PDTL formed between two slots disposed on both sides of a dielectric plate. Furthermore, a slotted plate, a lens supporting base, and a dielectric lens are disposed one on another.

Title: Procede et appareil destines a la culture de plantes
Inventor: TAKAYANAGI EIFU
IPC: A01G31/02

Granted: 2002-09-24
Abstract: Cette invention concerne un procédé et un appareil destinés à la culture de plantes. Cet appareil possède un structure qui va favoriser la croissance des racines sans entraîner leur pourrissement, ceci même lorsque les plantes sont suffisamment immergées jusqu'à leurs racines dans une solution de culture. Cet appareil permet également d'apporter l'oxygène nécessaire à la croissance des racines, et de freiner la prolifération de micro-organismes. Il permet en outre de réduire les coûts de la culture à un niveau compétitif par rapport à ceux qu'engendre une culture en milieu extérieur, ceci en utilisant efficacement et au maximum les rayons de lumière émis par des lampes fluorescentes. Cet appareil permet ainsi de réduire la consommation électrique qui représente la plus grande partie des coûts de la culture des plantes. Il permet aussi d'éviter l'apparition de défauts d'origine thermique, tels que des brûlures ponctuelles, ceci en réduisant au minimum la quantité de calories générées par les sources de lumières (lampes fluorescentes). Cette invention concerne aussi un procédé de culture de plantes à l'aide d'une source de lumière artificielle, lequel procédé consiste à immerger les racines des plantes dans une solution de culture qui contient des composants de type engrais. Ce procédé consiste ensuite à faire croître les plantes en utilisant de l'air à forte teneur en dioxyde de carbone que l'on pompe et que l'on fait pénétrer de manière forcée et continue dans la solution de culture, ceci pendant tout le processus de culture. Ce procédé fait appel à une structure dans laquelle les racines des plantes se trouvent en immersion constante et suffisante dans la solution de culture (54). On utilise des lampes fluorescentes (16) en qualité de source de lumière artificielle, tandis que la surface interne de la chambre de culture des plantes est entièrement recouverte d'une couche réfléchissante (6). Cette couche permet de réguler la puissance de chaque lampe fluorescente et de faire croître les plantes à l'aide de la puissance lumineuse minimale et nécessaire, ceci en utilisant de 30 à 70 % de la puissance nominale des lampes fluorescentes.

Granted: 2010-06-29
Abstract: A web server configured to respond to client requests over a network such as the World Wide Web includes a web listener having a Hypertext Transfer Protocol (HTTP) daemon, a plurality of extension programs configured to perform respective operations, and a web request broker configured to identify one of the programs for responding to a client request, and determine the availability of an instance of the identified program. The web request broker maintains control of multiple instances of each server extension program to provide enhanced server operation without overwhelming server resources. The web request broker maintains a minimum number of instances of the identified program in memory, each executed in its own address space. The web request broker determines whether an available instance of the identified program is available from an existing number of instances, and selectively initiates a new instance of the program if no other instance is available. If no instance is available and the existing number of instances exceeds the maximum prescribed number, then the web request broker returns the reply to the web listener to send a reply over the network that the request was not processed.

Abstract: Cardiopulmonary interval training between a user high target heart rate and a user low target heart rate is obtained with an exercise apparatus (10, 60) by increasing the load (130) of the exercise apparatus (10, 60) at a first predetermined rate until either the maximum machine load is obtained (134) or the high target heart rate (132). When this event occurs, the load can then be maintained (136) at a fixed level for a predetermined time. Thereafter, the load is decreased (138) until the low target heart rate is obtained (140), or the user-set exercise duration expired. The heart rate of the user is monitored during the exercise. In the event that measurement of a valid heart signal is lost at any time (140), any increase or decrease of the load of the exercise apparatus is terminated (142) until a valid heart rate signal is reacquired. In the case when an exercise apparatus is a treadmill (10), the load can be varied by increasing or decreasing both the speed adjustment and the elevation adjustment of the treadmill. In the preferred embodiment, the speed is first adjusted until a user-set maximum speed is obtained and thereafter the elevation is adjusted in order to obtain the load variations toward or from the high and low target heart rates. The exercise may be repeated between the low and high target heart rates to provide cardiopulmonary interval training.

Abstract: An apparatus (10) for transferring fluids into and out of the inner ear through the round window membrane. The apparatus (10) includes a cover member (12) sized for placement over the round window niche.  Fluid delivery and fluid extraction conduits (16, 50) are provided which are operatively connected to the cover member (12) so that fluids can pass therethrough. The cover member (12) is positioned over the niche to create a fluid receiving zone between the cover member (12) and the round window membrane. As a result, fluids can be delivered into or withdrawn from the zone. Alternatively a single conduit (102) may be used for fluid delivery and extraction.  Another variation uses a compressible cover member (202) positioned within the round window niche to form a fluid receiving zone between the cover member, and the round window membrane. The same type of conduit system described above is attached to the compressible cover member (202).
