Patent CA-2316792-A1 (CA)
Inventor: HARTE HORST
IPC: F04C14/28
Filed: 1999-10-21
Abstract: The invention relates to a drive head comprising a housing (12) with two passages (24, 26), which face away from one another, for a rod assembly (10) and a rotary-driven sleeve (30). Said sleeve surrounds a section of the rod assembly (10) and can be driven by a rotating drive. The rod assembly (10) is connected to the sleeve (30) by a coupling (40). A hydrodynamic recoil brake (60, 70) is provided for controlled reduction of the torsion power accumulated in the rod assembly (10). Said recoil brake in the operating mode conveys a fluid stream through a throttle point (90). In order to detect whether torsion power is accumulated in the rod assembly (10) which may present a potential danger, a pressure sensing device (102, 124, 126) is connected to the throttle point (90) and produces a signal if the pressure of the fluid exceeds a predetermined threshold value.

Patent CA-2323656-A1 (CA)
Title: Automatic call distribution system and method
Inventor: UKON SHINICHI
IPC: H04M3/60
Filed: 2000-10-18
Abstract: An automatic call distribution system is disclosed wherein a full-service called party can respond to ACD calls from the same caller. A caller specification number recognition section recognizes a caller number from an ACD call. A call preferential connection information inquiry section inquires a call preferential connection information database about the caller number and reads out a corresponding called party individual call number from the call preferential connection information database. A call connection processing section calls a corresponding ACD split in accordance with the called party call number and connects the ACD call to the called party call number. A call connection information automatic recognition section stores, when the called party responds and a talking state is entered, the caller number and the called party individual call number of the called party into the call preferential connection information database through a call preferential connection information storage section. When the called party is busy or in a termination rejection state and the ACD call cannot be connected to the called party, a call connection auxiliary processing section performs waiting processing and performs called party individual ACD call control processing or split individual ACD call control processing to connect the ACD call to one of called parties.

Patent CA-2341712-A1 (CA)
Title: Speech codec employing speech classification for noise compensation
Inventor: BENYASSINE ADIL
IPC: G10L25/90
Filed: 1999-08-24
Abstract: A multi-rate speech codec supports a plurality of encoding bit rate modes by adaptively selecting encoding bit rate modes to match communication channel restrictions. In higher bit rate encoding modes, an accurate representation of speech through CELP (code excited linear prediction) and other associated modeling parameters are generated for higher quality decoding and reproduction. For each bit rate mode selected, pluralities of fixed or innovation subcodebooks are selected for use in generating innovation vectors.  The speech coder distinguishes various voice signals as a function of their voice content. For example, a Voice Activity Detection (VAD) algorithm selects an appropriate coding scheme depending on whether the speech signal comprises active or inactive speech. The encoder may consider varying characteristics of the speech signal including sharpness, a delay correlation, a zero-crossing rate, and a residual energy. In another embodiment of the present invention, code excited linear prediction is used for voice active signals whereas random excitation is used for voice inactive signals; the energy level and spectral content of the voice inactive signal may also be used for noise coding. The multi-rate speech codec may employ distributed detection and compensation processing the speech signal. For high quality perceptual speech reproduction, the speech codec may perform noise detection in both an encoder and decoder.  The noise detection may be coordinated between the encoder and decoder.  Similarly, noise compensation may be performed in a distributed manner among both the decoder and the encoder.
