Filed: 2006-04-28
Abstract: A wood knot and a dead knot with bark can be infallibly detected. A piece of wood is imaged by imaging means (8). Image processing means (1) calculates the circularity of a portion of the captured image and judges the portion having a high calculated circularity as a knot. The knot portion is cut off from the wood image captured by the image processing means (1), parts cut off from the color space of the pixels of the knot portion with a predetermined threshold are judged as blackened parts, and the knot portion having a high ratio of the number of pixels of the blackened parts to the number of pixels of the knot portion is judged as a dead knot.

Title: Vehicle ignition interlock systems with multiple alcohol sensors
Inventor: MCMILLIN BRIAN
IPC: B60K28/06
Filed: 2006-04-24
Abstract: A vehicle ignition interlock system includes a breath analyzer and a controller operably connected to the breath analyzer and to an ignition system of the vehicle. The breath analyzer detects breath alcohol level of a vehicle operator and prevents vehicle ignition if a breath alcohol level is greater than or equal to a threshold value. The controller requires the vehicle operator to periodically take breath analyzer "retests" after vehicle ignition in order to allow vehicle operation to continue. The breath analyzer includes first and second alcohol sensors. The second alcohol sensor is a backup for the first alcohol sensor and becomes operational if the first alcohol sensor malfunctions. The first or second alcohol sensors may be a mouth contamination sensor that distinguishes between mouth contaminants and alcohol contained within a deep lung breath sample. The system also includes sensors configured to detect impact (abuse) and vehicle motion.
Patent CA-2608000-A1 (CA)
Inventor: CEREMONY JEFFRY
IPC: G02B21/06
Filed: 2006-05-09
Abstract: Nonuniformities in the efficiency of detection of individual fluorescing reaction mixtures in a well plate with a two-dimensional array well array are corrected. The nonuniformities arise both from the stimulation pattern and the detection pattern, and are corrected by adding additional segments to a pair of segmented mirrors. The additional segments are oriented to direct light to the outermost reaches (i.e., the four corners) of the array and thereby produce a stimulation pattern that has a greater intensity in the outermost regions. This compensates for a radial decline in the efficiency of the detector in detecting the emissions from the well plate, the radial decline being an artifact of systems that utilize CCDs or similar components as detectors.

Abstract: L'invention concerne un dispositif ou un système de communication sans fil générant une rétroaction de commande de puissance de transmission pour un canal de commande de puissance reçue par la détermination d'un taux d'erreur de commande (CER), ou par l'identification d'une qualité de signal cible pour le canal de commande de puissance, selon une fonction de mappage définie "qualité de signal sur CER". En général, le canal de commande de puissance ne comprend pas des données codées d'erreur à utiliser pour une estimation CER. Cependant, dans un mode de réalisation, le canal comprend des octets de référence connus évalués pour une estimation CER, le CER estimé étant utilisé pour définir la cible de qualité de signal pour une commande de puissance intérieure en boucle. Dans d'autres modes de réalisation, une probabilité d'erreur de réception calculée est utilisée pour identifier une estimation de CER selon une fonction de mappage définie "probabilité sur CER". Ces modes de réalisation d'exemples, de manière non exhaustive, peuvent être utilisés pour fournir une rétroaction de commande de puissance pour des instructions de commande de puissance transmises sur un canal physique fractionnel spécifique de systèmes AMRC large bande.

Abstract: The invention concerns a composite material part made by forming a fibrous preform (20), forming holes (22) extending in the preform from at least one side thereof, and densifying the preform with a matrix formed at least partly by a chemical vapour infiltration in gas phase (CVI). The holes (22) are formed by removing the material thereof by rupturing the fibers, for example by high-pressure jet machining, the fiber arrangement in the preform provided with holes being substantially unmodified relative to the original arrangement prior to the formation of the holes. The densification gradient is thus highly reduced, and a density may be obtained in a single densifying cycle which, in prior art, required several cycles separated by intermediate decrusting.

Inventor: CURTIS LARRY E
IPC: G01R22/06
Filed: 2006-06-28
Abstract: An automated integrated monitoring (IM) algorithm that automatically puts data from a utility monitoring system into context by temporally aligning the data to a common reference point and by identifying the location of each monitoring device in a hierarchy relative to other devices. Frequency variation data is received from all meters. The data is automatically aligned to a common reference point, such as a precise zero crossing, using a cross-correlation algorithm to determine the time delay at which the data is most correlated.  Once the data is aligned, power data is received from all meters in a hierarchy, and the monitoring system layout is auto-learned using a correlation algorithm to determine which two meters are most likely correlated with one another based upon their historical power readings. Once the layout is complete, additional decisions regarding hardware and software configuration can automatically be made by the IM algorithm.

IPC: G07C9/00

Abstract: A system to capture and to automate the maintenance of reference signatures for automatic signature verification systems. Generally, signatures as well as the identity of a person are captured from customer opening forms or recorded when subscribing for a service, which requires automatic signature verification. The identity (example customer name) and acquired signatures are stored into a database for later signature verifications required by business transactions. Rather than storing the initial reference signatures into the database, which is a manual time consuming process, signatures are taken from valid transactions and automatically stored into the database as a kind of reference signature. In paper based transactions the signature area of the document's image is taken and stored into the database as a so called "variant" to the reference customer or service identity. In paperless transactions the signature is taken directly from the input device and stored as a variant. This leads to a significant reduction in initial manual and continuous maintenance work needed. As individuals show variations in signatures over the years or they sign in two or several different forms (example: first name and last name or only last name), the signature reference database keeps the most up-to-date signature references without manual intervention.
