IPC: G10L19/22
Filed: 1996-07-26
Abstract: In a speech encoder, a gain codebook switching circuit is supplied with short-term prediction gains from a short-term prediction gain calculator circuit and with mode information through an input terminal and compares the short-term prediction gains with a predetermined threshold value when the mode information indicates a predetermined mode.  As a result of comparison, the gain codebook switching circuit produces gain codebook switching information which is delivered to a gain quantizer circuit.  The gain codebook quantizer circuit is supplied with adaptive code vectors, excitation code vectors, impulse response information, and the gain codebook switching information, and gain code vectors from a particular gain codebook connected to one of a plurality of input terminals that is selected by the gain codebook switching information.  For the excitation code vectors being selected, the gain quantizer circuit selects combinations of the excitation code vectors and the gain code vectors in the gain codebook selected by the gain codebook switching information.

Title: Method of recovering oxygen-rich gas
Inventor: HARUNA KAZUO
IPC: B01D53/047
Filed: 1996-02-26
Abstract: A method of recovering an oxygen-rich gas from a gaseous mixture mainly comprising nitrogen and oxygen by pressure swing adsorption using two adsorption towers (A and B) packed with adsorbents adsorbing selectively nitrogen, wherein the recovery of the oxygen-rich gas remaining as the result of pressure equalization between the two towers is conducted exhaustively and nitrogen is continuously withdrawn by suction by connecting a vacuum pump to either tower (A) or tower (B) without interruption.  To that end, the pressure equalization between the two towers (A and B) is conducted in at least two steps in such a manner that one tower (A or B) is increased in pressure, while the other tower (B or A) is decreased in pressure, so that the oxygen-rich gas can be recovered till the pressure difference between the two towers (A and B) decreases to almost zero.

Patent CA-2190664-A1 (CA)
Inventor: KASHI RAMANUJAN S
IPC: G06T7/00
Filed: 1996-11-19
Abstract: A signature verification method operates by comparing the numerical values of parameters evaluated on a trial signature with stored reference data derived from previously entered reference signatures. The parameters include global features of the signature, and also include a stroke-direction code (SDC) of thesignature. An SDC is derived by subdividing the signature into a sequence of time-ordered, spatially oriented line segments, each segment extending between a pair of discrete points along the signature. Each line segment has a stroke-direction value. The SDC is the ordered sequence of these stroke-direction values.

Title: Method and apparatus for testing object oriented programming constructs
Inventor: DALTON JOHN T
IPC: G06F9/45
Filed: 1995-05-12
Abstract: The invention provides methods and apparatus for generating, from a source signal defining a subject class to be tested (40), an inspection signal defining an inspection class (34) that has one or more members for: (i) generating a test object as an instantiation of the subject class or a class derived therefrom, (ii) invoking one or more of the selected method members of the test object, and (iii) generating a reporting signal based on an outcome of invocation of those members. The inspection class, as defined by the inspection signal, can include one or more method members (50f), referred to as "inspection members", for testing corresponding method members of the test object (and, therefore, in the subject class). So-called "test suite members"  (50a-50e), that are also defined as part of the inspection class, exercise the inspection members. The invention also provides methods and apparatus for responding to an inspection signal to create an inspection object instantiating the inspection class. Members of the inspection object are invoked to create the test object (80), to invoke method members thereof and to generate a signal reporting an effect of such invocation. The test object members can be invoked by corresponding inspection members of the inspection class, which in turn can be invoked by test suite members of the inspection class.
