Patent CA-2246084-A1 (CA)
Inventor: ESTE GRANTLEY OLIVER
IPC: H01L21/3065
Filed: 1998-08-28
Abstract: A method of patterning a brittle material, and particularly a semiconductor material, is provided comprising ion implantation induced selective area exfoliation. The method includes steps of masking the material, implanting unmasked regions of the material, with light ions of Hydrogen or Helium, and rapid thermal annealing at the temperature causing exfoliation of the material from the implanted regions. As a result, the material is patterned to a depth determined by the depth of ion implantation. The method allows patterning through crystalline or non crystalline materials, or several layers of different materials at the same time. When the mask has straight sharp edges aligned parallel to natural cleavage planes of the semiconductor material, the exfoliation results in formation of high quality sidewall-facets of exfoliated material and of the remaining patterned material at the boundaries of exfoliated regions.

Title: Arresting material test apparatus and methods
Inventor: CIESIELSKI MICHAEL S
IPC: G01N33/38
Filed: 1998-02-06
Abstract: Arresting material test apparatus, test probes and methods enable testing of compressive gradient strength of cellular concrete, and materials having similar characteristics, on a continuous basis from the surface of a section to a typical internal penetration depth of at least 60 percent of thickness. Previous testing of cellular concrete typically focused on determining a minimum structural strength prior to structural failure or shattering of a test sample. For an aircraft arresting bed, for example, cellular concrete must exhibit a compressive gradient strength in a relatively narrow precalculated range continuously from the surface to penetration depth equal to 60 or 80 percent. Precalculated and controlled compressive gradient strength is critical to enabling an aircraft to be safely stopped within a set distance, without giving rise to drag forces exceeding main landing gear structural limits. Test apparatus, test probes with post-compression build-up relief and test methods are described.

Abstract: Provided are automated methods for distinguishing and differentiating cells in a whole blood sample. In one of the methods, a whole blood sample is provided. One or more tests to be performed on the whole blood sample is selected. The tests to be performed on the whole blood sample are correlated. A volume of the whole blood sample is aspirated into an automated instrument system which automatically performs conventional hematology analysis and fluorescent cytometry analysis on the whole blood sample. A first aliquot of the whole blood sample is dispensed into at least one sample receiving vessel. The first aliquot of the whole blood sample is mixed with a fluorescent reagent. The first aliquot of the whole blood sample mixed with fluorescent reagent is diluted and transported through a flow transducer system. The flow transducer system detects multi-angle light scatter and fluorescence from the first aliquot of the whole blood sample mixed with fluorescent reagent and counts and differentiates platelets or platelet clumps or both in the sample. Detecting and differentiation data for the one or more tests performed on the whole blood sample are stored.  Results of the one or more tests performed on the whole blood sample are reported in a quantitative manner if so requested. The instrument system automatically performs all method steps without physically separating cells from the whole blood sample or an aliquot of the sample and results of a conventional hematology analysis may be utilized in at least reporting of results of the fluorescent cytometry testing.

Patent CA-2260719-A1 (CA)
Inventor: HOWARD BRETT
IPC: H04L9/00
Filed: 1999-02-04
Abstract: There is provided a system and method for encoding and decoding of secured data. Decoding of secure data within a receive buffer is performed by a processor dedicated to that function. The processor accesses the data from a data port other than the bus used by a first processor. In this fashion, the data bus of the first processor is free for other operations while ciphering operations are underway. Also, the data is ciphered and hashed for data integrity in parallel to improve performance. Because the dedicated processor is not in direct communication with the data bus, it is clocked by a different clock and can therefore be designed economically to meet throughput requirements of a given system.

Patent CA-2264471-A1 (CA)
Title: Method and apparatus for inter-frequency hand-off in wireless communication systems
Inventor: KUO WEN-YI
IPC: H04B7/12
Filed: 1999-03-05
Abstract: An apparatus and method which, in a wireless communication system, improve the quality of inter-frequency hand-offs from an existing call connection frequency to a new frequency by minimizing oscillating inter-frequency hand-offs between the existing call connection frequency and the new frequency, and by minimizing redundant and unnecessary tuning and searching at the new frequency. The present invention accomplishes this improvement by adding specific threshold comparison values (or triggers) within existing messages and through more robust data reporting, from the mobile unit to the base station, when tuning and searching is performed.  Particularly, two comparative triggers provided by the present invention avoid unnecessary tuning and searching in the new frequency, thus reducing voice degradation and the risk of dropped calls while pilot searching in the current frequency. Additionally, an alternative embodiment of the present invention compares received power in the new frequency to the received power in the original frequency. If the received power in the new frequency does not exceed the received power in the original frequency by a specified hysteresis threshold value, then a search of the new frequency is unnecessary and the mobile unit "retunes" to the original frequency.
