Title: Methods for determining the depth of defects
Inventor: DEVITT JOHN WILLIAM
IPC: G01N25/72
Filed: 2004-06-17
Granted: 2010-02-09
Abstract: A method facilitates inspection of a component surface (28). The method comprises positioning a surface of the component (10) to be inspected in an optical path (24) of at least one infrared radiation detector (26), heating the component surface using electromagnetic radiation to cause an increase in radiance from a defect (70) present at the component surface, and detecting temperature variations within the component surface using the at least one infrared radiation detector, such that the surface irradiance is measured at predetermined locations across the component surface. The method further comprises detecting cracks in the component by analyzing radiation transient response data received by the infrared radiation detector, and correlating the temperature variations to the radiation transient response data to determine a depth of the detected cracks.
Patent CA-2473868-C (CA)
Inventor: STEARNS DAVID N
IPC: A01G13/10
Filed: 2003-01-13
Granted: 2005-07-05
Abstract: The novel seedling bud capping device is easily deployed on a bud of a seedling due to the use of adherent on either edge (rather than a staple), a nd more particularly due to its predefinedly selective use of adherent to form an inverted conic space around the bud for receiving sunlight and for capturing the bud stem near its base. The paper stock or the adherent used in the bud capping device may be impregnated with a repellent scent to further ward awa y browsers to protect the seedling. Preferably, the bud capping device is maad e from a small, e.g. ~5 inch, square piece of water-repellent paper stock havi ng a layer of glue adjacent at least one edge. The stock is prootected on the adherent side by another layer of material to be selectively removed. This protective layer is scored and a free segment of the protective backing laye r is removed to expose a region of adherent. Because the adherent is wider at the base than at the top, when the devid is deployed near a terminus of a seedling bud, it grasps the base of the bud'sstem at a fulcrum of an inverte d cone while leaving open the top of the device for exposure to sunlight. The bud capping device prevents browsing of a fragile seedling while permitting the seedling to thrive. The bud capping device may be affixed with a pull-ta b scent device of any suitable configuration, preferably with a slow-release animal repellent. The device may be arranged and mass-produced in laminar sheets, cut and formed into rolls for easy dispensing.

Abstract: Methods and apparatus for selecting a cellular network to provide one or more communication services for a mobile communication device are disclosed. A  scanning operation (305) is performed by the mobile device to identify a plurality of cellular networks that support a voice communication service in a geographic coverage area. The mobile device then identifies which of the cellular networks makes a data communication service available to it (335, 405). Advantageously, the mobile device assigns priority to or selects a cellular network that makes the data communication service available over a network that fails to make the data communication service available, and may register with that network. The data communication service may include, as examples, an e-mail communication service or an Internet access service.  Preferably, the cellular network operates in accordance with GSM (Global System for Mobile) and GPRS (Generalized Packet Radio Service). In an embodiment, a network is selected which makes the largest number of preferred services available. In another embodiment, a network is selected which has the highest sum of service specific weight values.
