Title: Phase retrieval in phase contrast imaging
Inventor: POGANY PETER ANDREW
IPC: G03B42/06
Filed: 1997-12-24
Granted: 2005-10-18
Abstract: A method of obtaining an image of the phase change introduced by an object in penetrating radiation incident on the object includes irradiating the object with penetrating radiation having high lateral spatial coherence, and receiving at least a portion of the radiation at a detector after the radiation has emerged from the object and thereby obtaining and storing at least two intensity records for the received radiation each including intensity values at predetermined intervals. These values are utilised to derive a grid of values defining an image of the phase change introduced by the object in the penetrating radiation. The intensity records are obtained at a uniform finite distance after the radiation has emerged from the object, and are for respective different energy distributions of the detected radiation. Apparatus is also disclosed.

Patent CA-2279164-C (CA)
Inventor: DECKER OWEN H
IPC: C08F2/46
Filed: 1999-07-30
Granted: 2003-01-21
Abstract: This invention provides a UV curable powder coating composition comprising a particulate blend of a non-crystalline unsaturated polyester base resin, a crystalline unsaturated crosslinker resin co-polymerizable with the base resin, and a photoinitiator, that exhibits reduced or eliminated having in the cured coating formed therefrom upon being cured at low temperatures demanded by certain heat sensitive substrates. This is accomplished by incorporating in the powder composition a recrystallization or haze inhibitor which is comprised of a crystalline epoxy resin. When this powder blend is melted for curing, the crystalline crosslinker resin visually appears to separate and recrystallize out of the molten powder less completely than it does in the absence of the recrystallization or haze inhibitor. This prevents a visible haze from developing on the surface of the coating upon curing with UV radiation.

Abstract: A ground opener unit for a seeding or planting unit includes an arm attachable to an implement frame and a disc rotatably mounted to the arm for forming a furrow in the ground. A scraper assembly includes a scraper plate defining a scraper edge for contacting and scraping a surface of the disc. The scraper plate defines a mounting region remote from the edge. A scraper plate mount secures the scraper plate adjacent the disc and a resilient pad of material is interposed between the plate mounting region and the scraper plate mount. A spaced pair of fasteners extend through the mounting region to secure the scraper plate and resilient pad to the scraper plate mount. The fasteners are located in selected positions in the mounting region relative to the resilient pad such that the scraper plate is capable of being tilted or rocked when said scraper edge encounters irregularities thus assisting the scraper edge to follow the disc surface during use.

Abstract: A file transfer device, system, and method are provided.  The device, system, and method enable a variable number of data transfers and include an initial connection system and a data transfer system. The initial connection system establishes a connection between at least two devices via predetermined listening ports, with at least one predetermined listening port residing within each of the at least two devices. The initial connection system also dynamically assigns a first data port within a first device, and transmits the address of the first data port to a remaining device via the predetermined listening ports. The data transfer system is for each of the variable number of data transfer operations. The data transfer system dynamically assigns a corresponding second data port within the remaining device and transfers data between the connected devices via the data ports so that the data is substantially simultaneously transferred between a variable number of devices via the data ports. Each pair of first and second data ports is established in response to each listening port connection.

Abstract: A call center is configured such that voice prompts provided to a given caller are modified based on prior e-mail notifications or other non-telephonic communications between the call center and that caller. In an illustrative embodiment, information regarding at least one previous non-telephonic communication with a given caller is stored in a database or other memory accessible to the call center. When the given caller places a subsequent call to the call center, the call center retrieves the stored information for that caller, and selects voice prompts for the caller based at least in part on the e-mails or other non-telephonic communications previously sent to the caller. The call is then routed to an appropriately-skilled agent based at least in part on a response of the caller to the voice prompt. Additional information relating to the previous non-telephonic communication, e.g., a copy or summary of the communication, may be transmitted to the agent that receives the call.

Abstract: Multiple public/private key pairs of varying levels of security are used to provide a high level of security while still allowing fast processing of encrypted information. The lower-security level includes keys which are small in length, which are changed relatively often, and which require less or fewer resources to implement their functions (130), (134). When it is required to change key pairs of low security, a key pair at a higher security level (i.e, longer length keys) than the lower-security level keys is used to transfer the new lower-security public keys to devices using those keys. The higher-security keys can, in turn, be changed at a frequency lower than the lower-security keys. The higher-security keys require a higher level of resources to perform their coding operations (120), (124). This approach of using keys of escalating levels of security to replace lower-security keys, where the higher-security keys require more resources, are more secure, and are replaced less often than the lower-security keys, can be followed as many times as is desired to create a hierarchy of public key uses with the result that the lower-security operations can be performed quickly while the overall system security is high.

Title: Method for quantifying antioxidants in foods and medical specimens
Inventor: SHANBROM EDWARD
IPC: G01N33/02
Filed: 2000-04-28
Granted: 2009-10-20
Abstract: A simple analytical method for determining antioxidant level in food product and body fluids such as urine is based on reduction of elemental iodine. The method adds an aqueous solution of iodine and an iodophor to the sample to be tested.  Polyvinylpyrrolidone is a preferred iodophor. Antioxidant materials in the sample reduce the elemental iodine and the reaction is monitored by measuring either a decrease in iodine or an increase in iodide ion. A preferred method of practising the invention is to measure the change in iodide ion with an ion selective electrode and an appropriate electronic meter. The method rapidly and inex-pensively produces antioxidant measurements that are comparable to those produced by more complex and cumbersome methods.
