Title: Vascular temperature measuring device and process for measuring vascular temperature
Inventor: VAN LANGENHOVE GLENN
IPC: A61B17/06
Filed: 2001-04-04
Abstract: The present invention provides a vascular catheter apparatus for temperature measurement of vascular tissue, comprising a flexible body (14, 15, 18), at least two thermal sensors (10) mounted on resiliently biased projections (11) depended from the body; and a carrier (13) for transmitting temperature data at the vascular wall from the sensors (10) to a remote device. A computer program associated with the vascular catheter apparatus is provided for manipulating image data and temperature data to generate an output in which the temperature data is mapped onto a corresponding position on an image where that temperature data was detected to provide an integrated graphical image output. The temperature data is thermography data that represents surface temperature at a vascular wall, and the image data is representative of the vascular wall morphology.

Abstract: C'est avec la venue du printemps que cette idée qui m'a parue si simple ma is toutefois assez compliquée m'est apparu. Je voulais principalement au début, un air climatisé pour me rafraîchir quand viendrait les journées torride de l'été. Etant donné que je loge a un endroit ou il m'est impossible de condamner une fenêtre, il me fallait trouver une autre alternative, j'ai fait des recherches et, mis a part l'air climatisé et le ventilateur conventionnel, qui ne fait que pousser l'air chaud ambiant, je n'ai rien trouver qui correspondait a mes besoins. Après mûre réflexion, j'ai donc eu l'idée de concevoir par moi-même un appareil qui aurait a 100% les caractéristiques que je désirais. Par conséquent, l'invention dont il sera question dans la présente servira à distribuer de l'air qui sera réellement refroidit par un système de congélation et ce utile autant pour une petite pièce que pour de grand espaces et même pour l'extérieure. Voici quelques exemples: chambre, logement, maison, local de travail, entreprise, patio et bien d'autre.

Patent CA-2452486-A1 (CA)
Inventor: CHRISTENSEN GRAHAM
IPC: H03K5/1536
Filed: 2002-07-03
Abstract: An apparatus in an electronic control system allows two or three wire operations. A power supply (150) can supply power to the enclosed circuitry in both two and three wire installations. Two separate zero cross detectors are used such that timing information can be collected in both two and three wire installations. Both zero cross detectors (110) are monitored and are used to automatically configure the electronic control. Over voltage circuitry senses an over voltage condition across a MOSFET which is in the off state and turns the MOSFET on so that it desirably will not reach the avalanche region. Over current circuitry senses when the current through the MOSFETs has exceeded a predetermined current threshold and then turns the MOSFETs off so they do not exceed the MOSFETs' safe operating area (SOA) curve. Latching circuitry (120) is employed to keep the protection circuitry in effect even after a fault condition has cleared. Lockout circuitry (130) is used to prevent one protection circuit from tripping after the other circuit has already tripped from a fault condition. The protection circuitry output is desirably configured such that it can bypass and override the normal turn on and turn off impedance and act virtually directly on the gates of the MOSFETs.  Preferably, the system has a high efficiency switching type power supply in parallel with a low frequency controllably conductive device.
