Filed: 1999-11-02
Abstract: A multifiber connector subassembly is provided that includes a ferrule and a multifiber alignment adapter for individually guiding the plurality of individual optical fibers into alignment with respective ones of the bores or microholes defined by the ferrule. In this regard, the ferrule includes a forward portion that defines the plurality of bores for receiving respective end portions of a plurality of optical fibers and a rear portion that defines an opening of a predetermined shape. The multifiber alignment adapter defines a plurality of lengthwise extending passageways for receiving respective ones of the plurality of optical fibers. The multifiber alignment adapter also has a forward end having an exterior shape that corresponds to the predetermined shape of the opening defined by the rear portion of the ferrule. As such, the forward end of the multifiber alignment adapter can be positioned within the opening defined by the rear portion of the ferrule such that each passageway defined by the multifiber alignment adapter is aligned with a respective bore defined by the ferrule. Accordingly, the multifiber connector subassembly can guide each individual optical fiber through a passageway and into the respective bore defined by the ferrule without being stubbed or otherwise damaged and without requiring that the optical fibers be ribbonized.

Title: Grating based phase control optical delay line
Inventor: FUJIMOTO JAMES G
IPC: G02B5/18
Filed: 1998-05-15
Abstract: An apparatus for performing high speed scanning of an optical delay and its application for performing optical interferometry, ranging, and imaging, including cross-sectional imaging using optical coherence tomography, is disclosed. The apparatus achieves optical delay scanning by using diffractive optical elements in conjunction with imaging optics. In one embodiment a diffraction grating disperses an optical beam into different spectral frequency or wavelength components which are collimated by a lens. A mirror is placed one focal length away from the lens and the alteration of the grating groove density, the grating input angle, the grating output angle, and/or the mirror tilt produce a change in optical group and phase delay. This apparatus permits the optical group and phase delay to be scanned by scanning the angle of the mirror. In other embodiments, this device permits optical delay scanning without the use of moving parts.

Patent CA-2297880-A1 (CA)
Inventor: RHINDRESS PAUL M
IPC: A01G9/00
Filed: 2000-01-29
Abstract: A transplant pot for plants that is formed when two identical pot halves are fastened together. The invention consists of three components; the main body of the invention where parts (side walls, guide tracks, gaskets and fastening mounts) are either molded into or affixed to the main body, the fastening screws and the drainage dish which is not required for structural integrity but merely for growing medium drainage. When the two halves of the invention are joined by the screws being tightened through the fastening mounts, which are molded to the side walls and threaded, the rubber compound gaskets are compressed thus creating a tight seal. When the plant requires transplantation the screws are removed from the fastening mounts to allow the pot halves to be separated. This permits the rooted plant to be removed with minimal disturbance to the plant's root system and other structures.

Title: A method of creating a unique authenticated identifier, its use within a digital registry system, and a business method based thereon
Inventor: GUTZ STEVEN JOHN
IPC: H04L29/06
Filed: 2000-09-27
Abstract: The algorithm of the present invention provides a means for legitimising user rights in digital objects obtained by indirect means. Processing a digital object with an authenticating algorithm generates a Digital Object Authenticity Code (DOAC), which can be recorded in a secure registry in association with a Participant Identification Number (PIN) for the originator of the digital object. Another participant in the system can use the authenticating algorithm to generate a DOAC for a digital object obtained by indirect means and compare such DOAC  to those stored in the registry to verify the authenticity of said digital object in question.  The participant may have the option of registering themselves as legitimate owners of an authenticated digital object in the secure registry, and if possible, attain rights to distribute said digital object. Relationships between the originator, the digital object, and any user/distributors will be recorded and stored in the secure registry. Incorporating a Transaction Processing System (TPS) into the system, enables a business method to be centered on the relationships between the originator-digital objects-user (and/or distributor).

Title: Method and apparatus for regulating heater cycles to improve fuel efficiency
Inventor: HAMMER JACK
IPC: F23N1/08
Filed: 1998-03-20
Abstract: A method and apparatus for improving heating system efficiency. An electronic circuit senses a firing signal from a boiler energy value sensor (26) such as a thermostat or pressuretrol. The circuit prevents the boiler energy value sensor from firing the burner, while the circuit senses an energy value of the outflow line (20) at the boiler (6). The circuit monitors the outflow energy value and records the outflow energy value at a first time of the firing signal. The circuit then continually monitors the outflow energy until it detects an energy drop from the initial outflow energy value. The circuit responds to the energy drop by firing the burner (10). The invention self-adaptively responds to present thermal load, reduces the number of on-off cycles, increases each burner run time while reducing total run time, improves fuel consumption, and reduces air pollution.

Title: Voice coding and decoding apparatus and method thereof
Inventor: OZAWA KAZUNORI
IPC: G10L25/93
Filed: 2000-11-09
Abstract: A mode discriminating circuit (300) extracts a feature quantity from a voice signal and makes mode discrimination. When the output of the circuit(300) represents a predetermined mode, a smoothing circuit (450) executes time-wise smoothing of at least either one of excitation gain, adaptive codebook gain, spectral parameter and excitation signal level. A multiplexer (400) locally reproduces a synthesized signal by using a signal obtained through the smoothing, and feeds out a combination of the outputs of spectral parameter calculating circuit, mode discriminating circuit, adaptive codebook circuit, excitation quantizing circuit and gain quantizing circuit. Thus it makes possible to provide a voice coding and a voice decoding apparatus, which permit good coded sound quality to be obtained for voice with background noise superimposed thereon even at a low bit rate.
