IPC: C09K11/00

Abstract: Absorption properties of an optically active medium can be changed drastically by a Fabry-Perot microcavity. Optically active medium of the cavity includes a host material which is not optically active and at least one rare earth ion which provides optical activity to the medium. The Fabry-Perot cavity is designed to be resonant with excitation wavelength of an absorption band of the host material. The excitation is provided by a source of radiation positioned such that the radiation impinges on the cavity at an angle within a range of from zero to less than 90 degrees from the normal to the top surface of the cavity. In one embodiment Er-implanted SiO₂ is used as the optically active medium. SiO₂:Er has an absorption band at 980 nm and an emission band at 1.55 µm due to 4f intra-atomic transitions of Er³⁺ ions. The Fabry-Pérot cavity is designed to be resonant with the 980 nm absorption band of SiO₂:Er. The efficiency of the cavity structure is much higher as compared to a no-cavity structure, while the spectral features of the active SiO₂:Er emission are unaltered. The structure can be used for optically pumped semiconductor devices, such as optical amplifiers or lasers, which could be operated with a higher overall efficiency.

IPC: G06F17/40

Abstract: Time of occurrence of an event, such as completion of rotation of a body, is determined by generating in response to the sensed occurrence of the event, a signal having a parameter whose value varies according to a predetermined function of time from an initial value at an initial time correlated to the time of occurrence of the event. At a subsequent time later than the initial time, a subsequent value of the parameter is determined and the time of occurrence of the event is determined by subtracting from the subsequent time, an amount of time calculated substantially according to the function as elapsing between the initial value and the subsequent value. By determining the times of completions of their respective rotations in this manner, the relative rotational phase and/or relative rotational velocities of rotating bodies, such as tyre/ wheel assemblies of a moving vehicle, can be determined with precision.

Title: High density rearing system for larvae.

IPC: A01K67/033
Filed: 1993-12-09
Abstract: Method and apparatus for rearing insects is disclosed. Information concerning the physical and dietary needs of the insect as well as behavioral characteristics are utilized to maximize the number of larvae reared per unit surface area of diet and per unit of rearing area while minimizing the amount of labor and materials required. An enclosed rearing unit is provided which can be located within an appropriate environment for rearing the insects. There are three sections within the rearing unit: 1) a diet space, 2) a larval space, and 3) a frass space. The diet space includes an appropriate diet medium for the insects. The larval space is located below the diet space and includes a series of vertical partitions perpendicular to and in contact with or nearly in contact with the diet medium such that the insect larvae are able to disperse themselves over the partitions. The frass space is located below the larval space such that any frass collects within the frass space as it is produced and does not interfere with the larval space or the diet space. The rearing system can further include an emergence pan including an outlet for allowing emerging adults to enter an oviposition cage. The emergence pan replaces the frass collection pan when all of the larvae have pupated. The rearing unit is turned upside down such that the emergence pan is located above the larval space and the diet space.

Abstract: Sonde laser à émission d'ultrasons pour usage intravasculaire, du type dans lequel un élément transducteur comporte une surface réceptrice d'ultrasons en matériau polymère piézo-électrique et une fibre optique avec une extrémité orientée vers l'avant à partir de cette surface et conçue pour recevoir un rayonnement laser en vue de sa transmission par la fibre optique et de son émission à ladite extrémité de celle-ci. La fibre optique est couplée à des moyens formant une source laser capables de produire alternativement, soit un faisceau laser de puissance moyenne relativement basse qui, lorsqu'il est modulé ou pulsé et émis par l'extrémité de la fibre optique et qu'il touche une cible, produit des ultrasons dont l'intensité permettra à l'élément transducteur de les capter et de les convertir en signaux de contrôle électriques, soit un faisceau laser de puissance moyenne relativement élevée qui, lorsqu'il touche la cible, peut en réaliser l'ablation, l'élément transducteur étant suffisamment solide pour résister aux ultrasons qui sont produits à ce moment aussi. Le faisceau laser de puissance moyenne relativement basse peut avoir une première longueur d'ondes à laquelle, lorsqu'il est modulé ou pulsé et émis par l'extrémité de la fibre optique dans un fluide qui absorbe fortement cette longueur d'ondes, il provoquera la production et la propagation dans ce milieu d'ultrasons d'une intensité telle qu'ils seront réfléchis par une cible en contact avec ce fluide et captés par l'élément transducteur qui les convertira en signaux de contrôle électriques. Le faisceau laser de puissance moyenne relativement élevée a ensuite une longueur d'ondes à laquelle ledit fluide est transmetteur et qui permet, lorsque le faisceau touche ladite cible, d'en réaliser l'ablation, l'élément transducteur étant suffisamment solide pour résister aux ultrasons qui sont produits à ce moment aussi.
