Filed: 1999-03-16
Abstract: A wireless communication device (100) contains a prefix storage area (128) containing one or more prefixes that may be automatically pre-pended to a destination telephone number. The destination telephone number may be entered manually by the user using a keypad (118) or automatically entered from a telephone number storage area (126). The system (100) analyzes the destination telephone number and determines whether one or more prefix pre-pending levels have been enabled. If enabled, the system automatically pre-pends the selected prefixes to the user-entered destination telephone number to generate a complete destination telephone number. The automatic pre-pending can extend to all telephone numbers entered by the user, or may be limited to telephone numbers in the telephone number storage area (126). Similarly, the system can be enabled continuously, or may be disabled when the user turns off the wireless communication device (100).

Title: Low dispersion singlemode optical fiber with non-constant index profile
Inventor: DULTZ WOLFGANG
IPC: G02B6/036
Filed: 1999-08-23
Abstract: The invention relates to a single-mode low-dispersion optical fiber for wavelength division multiplexing (WDM) of an optical transmission link, comprising a central fiber core with a radius r1, two inner layers of cladding with an outer radius r2 or a, whereby a is greater than r2, and an outer layer of cladding, whereby the refractive index n(r) of the fibers is inconstant as a function of the fibre radius r (a triple clad fiber). A fiber with a low dispersion in the wavelength range of approximately 1400 - 1700 nm, i.e. in the third optical window, can be manufactured using conventional production methods by selecting the appropriate profile and refractive index differentials between the core and or cladding without increasing the attenuation of said fibers. The transmission quality and output of an optical transmission link is increased by the inventive fibers in comparison with other standard optical fibers.
Patent CA-2341304-A1 (CA)
Inventor: WOOD WILLIAM I
IPC: C12N15/11
Filed: 1999-09-08
Abstract: The invention concerns compositions and methods for the diagnosis and treatment of neoplastic cell growth and proliferation in mammals, including humans. The invention is based upon the identification of genes that are amplified in the genome of tumor cells. Such gene amplification is expected to be associated with the overexpression of the gene product as compared to normal cells of the same tissue type and contribute to tumorigenesis.  Accordingly, the proteins encoded by the amplified genes are believed to be useful targets for the diagnosis and/or treatment (including prevention) of certain cancers, and may act as predictors of the prognosis of tumor treatment.
