Abstract: The  encoder  unit of the vocoder device includes the AR code-book,  the  MA  code-book,  and  the voice source code-book storing code words each corresponding to a set of the AR, the MA, and   the  voice  source  parameters,  respectively,  which  are obtained beforehand by means of the "analysis by synthesis" of a multitude  of  speech  waveform examples and then clustering the resulting  respective  parameters.  The AR preliminary selector, the  MA  preliminary  selector, and the voice source preliminary selector  select  from  respective  code-books  a  predetermined finite  number  of  code  words  approximating  the input speech signal,  and  in  synchronism  with  the  voice  source position detected  by  the  voice  source  position  detector  the speech synthesizer synthesizes a number of synthesized speech waveforms corresponding  to  the  combinations of the selected AR, MA, and voice  source  parameters.   Comparing the  synthesized  speech waveforms  with  the  current  input speech signal waveform, the optimal  code  word  selector selects the combination of the AR, the MA,  and  the  voice  source  code  words  having a minimum distance to the input speech signal waveform.

Patent CA-2102977-C (CA)
Inventor: ASADA HIDEKAZU
IPC: G03G15/20
Filed: 1993-11-12
Granted: 1999-07-27
Abstract: The present invention relates to a fixing device for use in image recording apparatuses, wherein the toner-adhering face of a sheet (100) onto which toner has been transferred is heated by a heating roller (30) to fix the toner.  A pressure roller (20), pressing itself against the heating roller, assists in the heat-fixing process.          In order to compensate for the curl resulting from the heat of the heating roller (30), a curl correcting roller (40) heats the back side of the sheet (100) with heat transmitted from the heat conducting part (31) of the heating roller (30) to another heat conducting part (41).          This configuration dispenses with a built-in heat source which the curl correcting roller (40) would otherwise need.

Title: Encoding method and decoding method of color signal component of picture signal having plural resolutions
Inventor: TAHARA KATSUMI
IPC: H04N19/423
Filed: 1993-12-09
Granted: 2003-09-09
Abstract: In an encoding and decoding method of color signal components of picture signals having a plurality of resolutions, an encoding system and a decoding system can be obtained color pictures with higher definition, so that color different signals in a format of the macroblock of 4:4:4 are encoded by a circuit 102.      These color difference signals with the highest definition are down-sampled by a down sampling circuit 103 and then encoded by a circuit 101. These color difference signals with intermediate definition are further down-sampled by a down sampling circuit 104 to produce the color difference signals with the lowest definition. These color difference signals in a format of the macroblock of 4:2:0 are supplied to and encoded by a circuit 100. Data output from the circuits 100, 101, and 102 are composed by a combining circuit 105 and transmitted.
Patent CA-2115602-C (CA)
Title: Routing calls destined for inaccessible destinations
Inventor: DEVITO NICHOLAS MICHAEL
IPC: H04Q3/00
Filed: 1994-02-14
Granted: 1997-11-11
Abstract: An arrangement for selectively routing traffic to alternate destinations. If the network or switch for accessing the primary destination is inaccessible (i.e., out of service), as opposed to simply being busy, calls are routed to an alternate destination; however, if the primary destination is simply busy, calls are not routed to any alternate destination. This is useful, for example, for emergency (E911) calls which are routed to alternate emergency bureaus only if the network or switch for accessing the home bureau is out of service. Alternatively, the tandem switch can select an alternate toll carrier on the basis of allocation of traffic to different alternate toll carriers. The same general kind of arrangement can be used to route calls to an alternate toll carrier if the preferred toll carrier selected by the customer is not accessible.

Abstract: A thermally-actuated steam trap,  which performs the opening and closing operations of a valve according to a change in the volume of an expansible medium  comprises at least two diaphragms and a valve member fitted to the lower diaphragm.  The lower diaphragm is shaped so that it comes to be more sensitive to a change in pressure than the upper diaphragm, to provide a steam trap which permits a discharge passage to be opened also when the fluid pressure at the inlet side is relatively week, and which is stable in operation from the initial stage as the opening and closing operations of the valve are performed intermittently.

Title: Source verification using images
Inventor: JOHNSON WALTER A L
IPC: H04N1/44
Filed: 1994-07-21
Granted: 2001-02-06
Abstract: Original source verifying data defining a first source verifying image are stored in memory. The first source verifying image can be produced by a human making marks by hand in a field of a form, which can then be provided by a scanner or a facsimile transmission through image input circuitry. If a second source verifying image is received that is the same as the first source verifying image, an operation is performed that would not be performed if the images were not the same, such as an operation accessing a related item of data. For example, the first source verifying image can be received with a document image, and data defining the document image and the original source verifying data can be stored so that a source verifying image that is the same as the first source verifying image must be received before an operation can access the document data and provide it to image output circuitry for printing or facsimile transmission. As a result, the marked form is analogous to a key: Only someone who possesses the marked form or a high quality copy can obtain access to the document data. If the marked form is lost or destroyed, the document data cannot be accessed.
