Title: Instability eradicating method and device for analysis-by-synthesis speeech codecs
Inventor: LAFLAMME CLAUDE
IPC: G10L19/12
Filed: 1997-04-07
Granted: 2003-02-11
Abstract: A method and device eradicate the occasional instability inherent in analysis-by-synthesis speech/audio codecs and caused in particular by channel errors during transmission of highly periodic signals such as high-frequency sine waves. Analysis-by-synthesis techniques involve production, in response to the speech/audio signal and at regular time intervals called frames, of (a) a set of spectral parameters for use in driving a synthesis filter in view of synthesizing the speech/audio signal, and (b) a pitch gain for constructing a past-excitation-signal component for supply to the synthesis filter. In accordance with the instability eradication method, a first step consists of detecting a set of conditions including (i) a resonance condition assessed from the spectral parameters, (ii) a duration condition detected when the resonance condition has prevailed for at least the M most recent frames, M being an integer greater than 1, and (iii) a gain condition which evidences consistently-high values of the pitch gain in the N most recent frames, N being an integer greater than 1. To eradicate the occasional instability, the pitch gain is reduced to a value lower than a given threshold whenever these three conditions are detected.

Title: Creation of bragg reflective gratings in waveguides
Inventor: ROURKE HOWARD NEIL
IPC: G02B6/124
Filed: 1998-04-27
Granted: 2007-01-09
Abstract: A method of avoiding unwanted phase discontinuities between adjacent sections of a long Bragg grating written section-by-section in an optical fibre uses masks with alignment parts additional to their writing parts.      Each alignment part is a replica of a portion of the writing part of the adjacent mask. Light of the same wavelength as used for writing grating sections excites stronger luminescence in regions of waveguide where there has been no irradiation induced raising of the refractive index than in regions where such index raising has occurred. Therefore, for such light directed through the alignment part of the mask and into the already-written previous section of the grating, the intensity of luminescent light propagating to an end of the waveguide varies according to how well or how badly the bright fringes produced by the mask register with the corresponding irradiated portions of the written Bragg grating. Fine adjustment of mask position is made to obtain the intensity corresponding to the desired level of registry before writing with this mask is commenced.

Abstract: The invention concerns a clamping device for detachably connecting two profiled parts (1, 19). There can be inserted and secured in a first profiled part (1) an inser t core (2) comprising an axially movable slide (7) with an end part having a projection (17, 18) which can be at least partially inserted into an opening in a second profiled part (19) in order t o exert clamping pressure against a portion of the second profiled part (19), which portion partially closes the opening. The slide (7) is flat, and the insert core (2) comprises two inner grooves for axially guiding the slide (7). Rotatably guided in the insert core (2) is an eccentric (5). When the eccentric head (4) is rotated, the eccentric roller (22) presses against the inner wall (30) of a recess (1 2) in the slide (7) in order to move the latter into the insert core (2) into a position which enables th e projection to exert the afore-mentioned clamping pressure.

Title: Container sealing surface area inspection
Inventor: JUVINALL JOHN W
IPC: G01N21/90
Filed: 1998-05-08
Granted: 2006-08-22
Abstract: Apparatus for inspecting the sealing surface area of a container finish that includes a structured light source positioned to direct a collimated line-shaped light beam onto the sealing surface area of a container as the container is moved relative to the light source. The line-shaped light beam at the container sealing surface area has a long dimension orthogonal to the container axis that extends chordally across the sealing surface area, and a narrow dimension tangential to the container axis. A light sensor is disposed to receive portions of the line-shaped light beam reflected from the sealing surface area, and provides an electrical output signal that varies with height or level of the sealing surface with respect to the light source and sensor. The sensor is coupled to associated electronics for providing information indicative of sealing surface height. The elongated dimension of the line-shaped light beam at the container sealing surface area accommodates wobble or misalignment at the sealing surface with respect to the light source and sensor. Furthermore, the elongated radial dimension of the line-shaped light beam at the container sealing surface area produces a reflection on the sensor from any wire-edge or over-press within the container mouth, thus producing at the sensor information indicative of both existence and height of any such wire-edge or over-press.

Title: Proximity-based registration in a communication system
Inventor: ROSE EILEEN PATRICIA
IPC: H04M3/42
Filed: 1999-01-28
Granted: 2002-07-30
Abstract: The invention in an illustrative embodiment provides binding and bridging between a mobile terminal and other more complex terminals in a communication system.  The binding is based on a determination of the proximity of the mobile to the other terminal, such that the mobile registers to different complex system terminals as it moves between different cells of the system. In accordance with the invention, a proximity-based temporary association is established, in a memory of a system switch, between the mobile and at least one other system terminal. While the mobile is "registered" in this manner to the other terminal, the mobile user can request permission to utilize the functions of the other terminal in order to, for example, receive incoming calls or place outgoing calls. Other embodiments of the invention provide proximity-based registration which utilizes a beacon device carried by the user, such that the user automatically registers to different system terminals as he or she moves about within the system.
