Patent CA-2155987-A1 (CA)
Title: Camera alignment device
Inventor: CORLEY FERRAND DAVID ERNEST
IPC: G03B15/06
Filed: 1995-08-14
Abstract: This invention relates to an improvement in a portable test pattern illuminator for illuminating a reference image so that the colour and tonal range of a camera focussed on the reference image can be balanced to enable the camera to produce a faithful reproduction of objects in a light source having similar characteristics of the general type having a screen with an opening; means for supporting a reference image object in said opening; and a light diffuser panel for transmitting light from a source to the reference object.  The improvement consists wherein the reference object is supported by the means for supporting the reference object in parallel relation to the surface of the light diffuser panel.  Yet a further improvement comprises providing a diffuser panel which has a peripheral non-specular reflector extending around its perimeter; said peripheral non-specular reflector having a non-specular reflective surface of substantially neutral coloration to reflect non-specular diffused light onto the marginal areas of the diffuser panel to achieve a more even light distribution across the face of the diffuser panel in use.  Yet a further improvement comprises  mounting a specular reflector at the back of the screen to reflect light from a source to the diffuser panel's surface, the plane of said specular reflector being at an angle of about 45 degrees to the plane of the screen, whereby the length of the light path from the source to the diffuser panel's surface is about the same for the full depth of the diffuser panel's surface.

Title: Digital video recorder
Inventor: OGURO MASAKI
IPC: H04N5/926
Filed: 1995-12-21
Abstract: A digital video signal is recorded in a first number of tracks in a standard play (SP) mode and in a second number of tracks in a long play (LP) mode, wherein each frame of the digital video signal is recorded in first and second sets of tracks in the SP mode and in only a first set of tracks in the LP mode, each track having subcode data recorded therein for locating frames during a high speed search of the record medium.      The digital video signal is compressed prior to recording in both the SP and LP modes, with the compression ratio being greater in the LP mode. When the digital video signal is recorded in the SP mode, the subcode data is of a first type for recording in the first set of tracks and is of a second type for recording in the second set of tracks; whereas when the digital video signal is recorded in the LP mode, only one type of subcode data is recorded. Hence, in the SP mode, a frame of compressed digital video signals includes subcode data of both types; and in the LP mode, a frame of compressed digital video signals contains subcode data of only one type.

Title: Tdma base station arrangement
Inventor: RUDOLPH COLIN
IPC: H04W16/02
Filed: 1996-04-11
Abstract: The area covered by a GSM base station can be increased in concentric rings of 35 km width by co-locating as many GSM transceivers as there are rings, the receivers of the transceivers being delayed by an amount equivalent to the round trip transit time for signals to transverse the inner rings. To enable idle mobiles to access the system each transceiver includes additional auxiliary receivers to receive access bursts on the frequencies of the other transceivers. Thus a mobile can access the system irrespective of the cell in which it is located even though it does not know in which cell it is located.

Patent CA-2180168-A1 (CA)
Inventor: MORMAN MICHAEL T
IPC: B32B3/30
Filed: 1996-06-27
Abstract: A multi-layered structure having improved liquid barrier properties is provided. The multi-layered structure includes a porous hydrophobic layer and a spacing layer adjacent to and in juxtaposition with the porous hydrophobic layer. The function of the spacing layer is to provided sufficient channels for a liquid while supporting all or substantially all of a compressive pressure exerted against the spacing layer. As such, when the spacing layer is contacted with a liquid, such as water, saline or a bodily fluid such as blood, and subjected to a compressive pressure, of at least 2 psi, applied generally perpendicularly to the spacing layer, the channels are available within the bulk of the spacing layer for such liquid to flow therein or therebetween, while all or substantially all of the compressive pressure is supported by the spacing layer. In this way, the liquid in contact with the spacing layer flows into these channels without passing through the porous hydrophobic layer.

Abstract: Stimulateur cardiaque sensible au rythme cardiaque implantable muni de circuits de détection de plusieurs paramètres physiologiques connus pour être représentatifs d'une demande métabolique du patient requérant un débit accru du coeur. Dans un mode de réalisation, le stimulateur sensible au rythme cardiaque est muni d'un détecteur d'activité détectant le niveau d'activité physique du patient, et d'un circuit de détection d'impédance permettant de connaître le niveau de ventilation-minute du patient par contrôle de l'impédance cardiaque. Une fonction de transfert sensible au rythme assurée par le circuit de commande du stimulateur calcule périodiquement une fréquence de stimulation sensible au rythme cardiaque en fonction des mesures recueillies par les deux circuits physiologiques de détection. Le rythme de stimulation du simulateur peut varier dans une plage définie par des limites supérieure et inférieure (programmables) prédéterminées. Dans le mode de réalisation préféré, l'influence des paramètres de détection d'activité et de ventilation-minute varie selon le rythme de stimulation en cours, et en particulier l'influence de l'activité détectée dans le calcul du rythme en accord avec la fonction sensible au rythme est supérieure à celle de la ventilation-minute pour les rythmes de stimulation bas, tandis que l'influence de la ventilation-minute détectée l'emporte sur celle de l'activité pour les rythmes de stimulation élevés. Le fonctionnement sensible au rythme du système est enregistré sous forme de données d'histogramme pendant une période d'observation prédéterminée. L'influence relative de l'activité détectée et de la ventilation-minute détectée sur le calcul du rythme est périodiquement adapté ou équilibrée sur la base d'une comparaison des données d'histogramme avec des données prédéterminées correspondant à la réponse désirée.
