Title: Method for eliminating telephone hold time
Inventor: SCHWARTZ FRED J
IPC: H04M3/38
Filed: 1998-09-24
Abstract: A method, which may be carried through a computer and its modem, is used to minimize the telephone time necessary to establish direct voice contact with the computer technician or other service provider and to provide information to the technician about the computer system and program. When contact is made through the modem with the information provider's PBX, the caller's computer would send a signal, indicating whether this is a reconnect or a new contact. If the customer support telephone line is for a number of programs or if there are different queues for different problems, a dialog box can be used to supply the necessary information to select the appropriate queue. The telephone system would provide an indication of the current wait time for the particular product or problem taking into account not only the open lines currently in the queue, but other callers who will be calling back at an appropriate time. The caller will then be informed of length of the wait and that the caller can (1) have the caller's computer automatically call back at the appropriate time without losing the place in line if the caller has a telephone connection to his/her modem; (2) call back on a telephone not connected to the modem with a priority number which will position the caller in the queue, if a caller does not have a handset attached to his/her modem;or (3) continue to hold. If the information provider desires, it can eliminate or limit the third option to a maximum hold period. If the caller wishes to call back, either through the computer or manually, the PBX generates a priority code corresponding to the place in line which is supplied to the caller's computer through its modem. At the call-back time, the computer will then place the phone call to the appropriate number and when answered by the customer service telephone number will supply the priority code and the caller will be placed in the queue based on the priority code. The caller's computer may at the time voice contact is made, forward system and diagnostic information.

Title: Method of controlling transmission power in cellular system and base station apparatus
Inventor: HAMABE KOJIRO
IPC: H04B7/005
Filed: 1999-03-24
Abstract: A signal is prevented from being transmitted from a mobile station to a base station with excessive transmission power for thereby increasing an uplink capacity. The base station compares the reception quality of the signal transmitted from the mobile station with target reception quality, and determines an increment for transmission power of the base station based on a compared result. The base station adds the increment to the transmission power of the base station based on a second control command transmitted from the mobile station, and transmits a first control command for controlling transmission power of the mobile station with the transmission power to which the increment has been added. If the reception quality of the signal transmitted from the mobile station becomes greater than the target reception quality, then the increment for the transmission power is increased. If the reception quality of the signal transmitted from the mobile station becomes smaller than the target reception quality, then the increment for the transmission power is reduced.

Patent CA-2269777-A1 (CA)
Inventor: COPNER NIGEL
IPC: G01M11/00
Filed: 1997-10-13
Abstract: A system and method for determining noise power levels across a range of frequencies of the optical signal output from a device operating at a specified optical power and drive current and, in particular, for determining relative intensity noise values (RIN). The system may comprise a reference laser for generating an optical reference signal and a photodetector for converting the optical signal output from the reference laser and the device under test into equivalent electrical signals. The system also comprises means for measuring ac and dc components of the electrical signals output from the photodetector. The system may be used to measure RIN levels to an accuracy of less than 1 dB. Such measurements are of particular importance in the field of fibre optic telecommunications. The reference laser is shot noise limited in the frequency range of interest, typically between 20 MHz and 20 GHz, and has a narrow linewidth, typically less than 5 kHz. A shot noise limited reference laser signal may be achieved by means of optically attenuating a higher power reference laser signal to the required lower optical power. The incorporation of a reference laser enables a simple calibration process to take account of factors such as the responsivity, gain and resolution bandwidth of the system apparatus across the whole measurement range.

Abstract: In an assembly for signal transfer between a receiving station (10) and a transmitting station (12) as well as for power supply of the transmitting station (12) in which these two stations are connected to each other via a two-wire line (14), an analog signal current variable between two limiting values is transmitted via this two-wire line, this signal current representing a measured value sensed by a sensor in the transmitting station (12). This current forms at the same time the supply current needed to operate the transmitting station (12). In the transmitting station (12) a circuit (24) is provided, generating a constant operating voltage for the transmitting station, the transmitting station including a controllable current source (34) which dictates the current flowing via the two-wire line (14) as a function of the measured value and which is fed from a supply voltage source (18) in the receiving station (10). The current regulator (34) is a series current regulator fed from the supply voltage source (18) in the receiving station (10). A charge pump (38) is connected to the output of the current source (34), the charge pump generating from the voltage appearing at the output of the current source (34) the operating voltage needed for operating the sensor (20) and a signal processing circuit (22) connected thereto. A parallel regulator (40, 42) for maintaining the input voltage or respectively the output voltage of the charge pump (38) constant is connected to the input and output respectively of the charge pump (38).

Abstract: The centrifugal liquid pump (1) is of the rotary discs types and has an integrated gas injector of very simple yet efficient structure. This pump (1) has a casing (3) defining an inner, substantially cylindrical chamber (5) with an axial liquid inlet (11) and a tangential liquid outlet (13). A rotary impeller (15) is rotatably mounted within the chamber (5). This impeller (15) has first and second spaced apart discs (17, 19) which are rigidly interconnected at such a distance away from each other as to extend close to the opposite walls of the chamber (5). The first disc (17) that extends close to the wall (7) into which the liquid inlet (11) opens has a central opening (21) of the same diameter as the liquid inlet (11) to allow the liquid injected through the inlet to enter within the chamber in between the discs.  The second disc (19) has a plurality of spaced apart openings (39) located at a constant radius, which is inferior to the radius of the discs. A coaxial power shaft (25) is connected to the impeller (15) so as to rotate it in a given direction. This shaft (25) extends out of the chamber (5) in a direction opposite to the liquid inlet (11). A gas feed pipe (31) is in open communication with one chamber (5). This gas feed pipe (31) is connected to a hole (35) made in the casing (3). This hole (35) is located in the second opposite wall of the chamber at a radial distance substantially equal to the above mentioned constant radius. In use, the pressurized gas fed through the hole (35) made in second opposite wall of the casing passes through the openings (39) made in the second disc (19) and enters into the chamber (5).  The gas is then dissolved in the liquid while the same moves between the discs (17, 19) toward the outlet (13) of the pump (1).
