Title: Method and apparatus to facilitate the support of communications that require authentication when authentication is absent
Inventor: BORELLA MICHAEL
IPC: H04M1/66
Filed: 2006-01-17
Abstract: A network element (300) having a mobile Internet Protocol call processor (301) is provisioned with at least a first mode of operation and a second mode of operation. The first mode of operation causes the processor to require authentication information from an authentication server before supporting a mobile Internet Protocol call whereas the second mode of operation permits the processor to support a mobile Internet Protocol call notwithstanding an absence of authentication information. A mode of operation selector (305) selects the mode of operation to be utilized and can respond to, for example, present unavailability of authentication services and/or administrative preferences. Pursuant to one approach, information such as accounting information can be developed and maintained as corresponds to mobile Internet Protocol calls that are supported in the absence of authentication.

Title: Methods for establishing legitimacy of communications
Inventor: SWAIN JOHN
IPC: H04L29/02
Filed: 2005-07-12
Abstract: A sender-side process directed to processing an electronic message destined for a recipient, comprising producing a solution to a computational problem involving at least a portion of the message. A degree of effort associated with solving the problem may be assessed. The message is further processed according to the degree of effort by determining whether the degree of effort was within a range set by the sender or the recipient and if not, the computational problem is adjusted and solved again. The message is then transmitted to a recipient, who is informed of both the problem and solution.  The recipient executes a recipient~side process, comprising: assessing the degree of effort associated with generation of the message based on the problem and solution; and further processing the message in accordance with the degree of effort. The degree of effort is indicative of the legitimacy of the message; e.g., is it "SPAM".

Title: Food grade antioxidant and flavorant from roasted wheat malt
Inventor: PIKE PAUL R
IPC: A23L7/20
Filed: 2006-08-17
Abstract: A food grade antioxidant and a baked food flavorant is isolated from roasted wheat malt containing bran. The germinated wheat is roasted until the malt's naturally occurring enzymes are substantially destroyed. The roasted wheat malt is milled into fine particles that may be physically separated into a fraction that is primarily homogeneous bran particles and into a fraction that is primarily heterogeneous endosperm and germ particles. The bran fraction is useful as a food flavorant and the endosperm and germ fraction may be used directly as an antioxidant for oils and fats, or foods, pharmaceuticals and cosmetics containing oils and/or fats or the antioxidant may be chemically extracted. The milled homogeneous bran and heterogeneous endosperm and germ particles may be recombined in customized proportions and thus used as a dually functional food ingredient.

Patent CA-2631322-A1 (CA)
Inventor: HAMA YUKO
IPC: C12Q1/68
Filed: 2006-11-29
Abstract: It is intended to provide a widely usable method of modifying chromosome without resorting to any specific enzyme or sequence and a method of identifying a gene that is essentially required in cell proliferation. First, a selection marker gene (B) allowing negative selection is integrated into the upstream or downstream of a target DNA region (X) and then the selection marker gene (B) and the target DNA region (X) are sandwiched between duplicated sequences. It is preferable that a DNA fragment having a sequence (A~) (which is a sequence being substantially the same as a specific sequence (A) located in the downstream of the target DNA region) and the selection marker gene (B) as described above is constructed and then this DNA fragment is integrated into the upstream of the target DNA region (X). Next, homologous recombination and negative selection are conducted so that the target DNA  region (X) can be easily removed from the chromosome. In the case where the chromosome contains no target DNA region (X) after the above-described treatment, it can be understood that the target DNA region (X) contains no gene that is essentially required in cell proliferation under the culture condition.
