Patent CA-2436250-A1 (CA)
Inventor: BOTELLA MESA JOSE RAMON
IPC: C12N15/82
Filed: 2001-12-07
Abstract: The present invention relates generally to methods for generating plants having altered phenotypes, and to plants so generated and parts of these plants. More particularly, the present invention relates to a method for modifying a plant so as to produce a plant exhibiting an altered phenotype. Particularly useful altered phenotypes contemplated by the present invention include plants having altered tissue architecture. The present invention further contemplates genetic sequences capable of facilitating the modification of a phenotype of a plant and to sequences complementary theret o and to derivatives of the sequences. Plants and parts of plants, such as flowering and reproductive parts including seeds, also form part of the present invention. The ability to modify the phenotype of a plant may be useful for, inter alia, producing plants with more highly desired characteristics, such as delayed flowering, increased lateral branching, delayed senescence and the like.

IPC: H01Q21/08
Filed: 2001-02-16
Abstract: A compact antenna system can generate RF radiation fields having increased beamwidths and bandwidths. The antenna system can include one or more patch radiators separated from each other by an air dielectric and by relatively small spacer elements. The lower patch radiators can be mounted to a printed circuit board that can include an RF feed network and a ground plane which defines a plurality of symmetrically, shaped slots. The slots within the ground plane of the printed circuit board can be excited by stubs that are part of the feed network of the printed circuit board. The slots, in turn, c an establish a transverse magnetic mode of RF radiation in a cavity which is disposed adjacent to the ground plane of the printed circuit board and a ground plane of the antenna system. The feed network of the printed circuit board can be aligned with portions of the cavity such that the portions of t he cavity function as a heat sink for absorbing or receiving thermal energy produced by the feed network.

Patent CA-2450488-A1 (CA)
Title: System and method for eliminating unsolicited e-mail
Inventor: IVEY CHRISTOPHER LIAM
IPC: H04L12/54
Filed: 2003-11-13
Abstract: The invention is a system and method for eliminating unsolicited e-mail. The invention employs the simple approach of limiting correspondence to known correspondents through a system of authentication, while allowing persons who are not authenticated correspondents to petition correspondence by means of an extremely restrictive message format that is useless for marketing purposes. The system uses a Header Parser [102] to sort all incoming electronic mail into solicited and unsolicited messages without parsing the message body. It allows unauthenticated correspondents to solicit correspondence by means of a specially tagged message format called a Request Correspondence Message, and makes use of a Format Inspector [103] to ensure that all such solicitations meet strict format requirements which make it impraticable to use such messages for the purposes of marketing or solicitation. Authenticated Correspondents are managed for each user with an Authentication Key Database [106]. The integrity of the system is maintained by means of a transactional exchange of authentication keys, which are transformed with each exchange to prevent keys from being intercepted and reused. This method allows users to maintain absolutely unique key signatures, which can be attached to message headers and sent in, clear without fear of interception or spoofing. This safeguard makes it impossible to share, sell, or compromise users' correspondent lists, and makes this approach to eliminating unsolicited e-mail unique from any similar method that employs correspondent lists.

Title: Apparatus for fractional rf signal synthesis with phase modulation
Inventor: HARRON GERALD
IPC: G06F1/02
Filed: 2004-03-09
Abstract: A method to improve the frequency resolution and phase noise of a synthesized RF signal results in superior instantaneous frequency change and phase modulation capability, wide frequency set ability, and suitability for implementation in a digital ASIC. The RF signal synthesis is achieve from a higher reference frequency clock signal using a variable pulse stretching technique.  The amount of the pulse stretch in each cycle is set by a phase increment value and is implemented using programmable delay lines. Pulse stretching can be extended beyond one cycle by pulse swallowing, allowing the generation of an RF signal with frequencies from DC up to the input reference frequency. Phase modulation is incorporated by digital control of the phase stretching with the phase modulation bits.

Filed: 2002-10-25
Abstract: A range of a wavefront sensor (36) is extended by focusing collimated light onto a lenslet array (33), an output creating a grid formed by edges of the lenslets (34) and a reference spot in the members of the grid.  Each reference spot has a known relationship to the grid member and a centroid. A  relationship between the reference centroids is determined. Next a wavefront emanating from an eye is focused onto the lenslet array (33), with the output from the lenslet array (33) forming the grid and aberrated eye spots thereon, each eye spot having a centroid. A  relationship between the eye spot centroids is determined. One known relationship between one reference centroid and the centroid of one eye spot is identified. Finally, at least some of the remaining relationships between the reference centroids and the eye spot centroids are determined. The determined relationships provide a measure indicative of the eye aberration.

Title: System and method of formulating queries in relational databases
Inventor: CAZEMIER HENDRIK
IPC: G06F16/248
Filed: 2004-04-29
Abstract: The invention introduces a method and system to automatically derive th e relationships between query subjects and query items within query subjects s o that problems such as those that result in double counting of information are avoided. It provides for creating a report by first defining a model based on an existin g database comprising two or more query subjects, each query subject comprising at leas t one fact query item and one primary key, then generating a hierarchy of sets and subsets of key query items within the model. Next a further fact is introduced into one of the query subjects. The expression is decomposed into sub-queries to prevent double counting of data in ambiguously defined situations. This is achieved using t he introduced fact to determine that such decomposition is required. Finally, t he data is accessed using the sub-queries, and a report is produced.
