Title: Method of estimating total volume of an irregular wetwell
Inventor: JORRITSMA JOHANNES N
IPC: G01F17/00
Filed: 1999-04-06
Abstract: For use with a wetwell having a geometrically regular upper portion and a geometrically irregular lower portion, a method is provided for estimating the volume in the lower portion. Upper and intermediate level sensors are provided in the upper portion of the wetwell, and a lower level sensor is provided in the lower portion. The volume between the intermediate and upper levels is first calculated. Then, the wetwell performs a series of cycles, each allowing the wetwell to fill with liquid between the lower level sensor and the upper level sensor while the pumping means is off or at a low rate, then causing the wetwell to be emptied from the upper level to the lower level by running the pump. During the filling part of each cycle, the time required for liquid to rise between the lower level and the intermediate level is noted, as is the time required for the liquid to rise between the intermediate level and the upper level. If these times are T2 and T1, respectively, the next step is, for each cycle, to multiply the upper volume (that between the intermediate and upper levels) by T2/T1, thus arriving at an estimate of the lower volume between the lower level and the intermediate level. Each such calculated estimate is stored, and all estimates are averaged to provide a good approximation of the actual volume between the lower and intermediate levels.

Abstract: A procedure for triggering a handdown or a handoff a mobile station served by a base station of a cellular wireless communication system. A tolerable path loss for signal links between the base station and a mobile station located within the base station's cell, is initially determined. A control signal is radiated at a known transmit power level from the base station over its cell. A receive power level threshold is determined for the control signal for reception by the mobile station, according to the transmit power level and the tolerable path loss. A handoff of the mobile station is triggered after deriving the received power level of the control signal at the mobile station, and determining that the received power level is less than the receive power level threshold. In one embodiment, a mobile station reports to a serving base station only after the former determines that the received power level of a control signal from the base station is less than a threshold level initially provided to the mobile station by the base station. The procedure is applicable, e.g., to base station cells of a first CDMA cellular system which cells border on cells of an analog (AMPS) or a second CDMA cellular system.
Patent CA-2277460-A1 (CA)
Inventor: NERON CHRISTIAN
IPC: G01S15/89
Filed: 1999-07-13
Abstract: A method and system is provided for enhanced ultrasonic detection and imaging of small defects inside or at the surface of an object. The Synthetic Aperture Focusing Technique (SAFT) has been used to improve the detectability and to enhance images in conventional ultrasonics and this method has recently been adapted to laser-ultrasonics. In the present invention, an improved version of the frequency-domain SAFT (F-SAFT) based on the angular spectrum approach is described. The method proposed includes temporal deconvolution of the waveform data to enhance both axial and lateral resolutions, control of the aperture and of the frequency bandwidth to improve signal-to-noise ratio, as well as spatial interpolation of the subsurface images. All the above operations are well adapted to the frequency domain calculations and embedded in the F-SAFT data processing. The aperture control and the spatial interpolation allow also a reduction of sampling requirements to further decrease both inspection and processing times. This method is of particular interest when ultrasound is generated by a laser and detected by either a contact ultrasonic transducer or a laser interferometer.

Abstract: An improved digital signal mixing architecture (100) for applications such as digital mixing consoles (76) is provided. The architecture provides a software configurable mixing system that is expanded up to more than 48 channels. The architecture comprises a master DSP (12) device coupled to a plurality of slave DSP devices (10) on a DMA bus (28). The master DSP (12) is interconnected to each of the slave DSPs (10) in a manner that enables the master DSP (12) to command each of the slave DSPs (10) to write the results of its input signal processing to the internal memory of each of the other slave DSPs (10). The master DSP (12) commands the slave DSPs (10) to transmit processed input signals to each other, so that each processed input signal is stored in the memory of each slave DSP (10). Once each slave DSP (10) has the results of every processed input signal, the master DSP (12) commands any combination of the slave DSPs (10) to mix any of the processed input signals to create a mixed signal that is sent to its outputs for conversion to an analog signal (18b). Mixing combinations are controlled by scripts that are interpreted by software. The digital mixing architecture (100) provides a system that is software configurable, so that mixing console is easily reconfigurable and upgradeable.

Inventor: KIRK DENNIS KEITH JR
IPC: B25F5/02
Filed: 2000-08-03
Abstract: A biscuit joiner (10) having a housing (16) which includes a forward portion (26), a handle portion (28) and a rear portion (30). A battery pack (56) is removably secured to the rear portion. The forward portion houses an electric motor (32) and is attached to a shoe assembly (12) and a fence assembly (14). The handle portion includes a stick handle portion (40) and a loop portion (42). Each of the stick handle and loop portions are laterally offset from the forward portion, and therefore from the rotational axis of the motor and the coaxial center of the housing. The stick handle portion is graspable by a user and the lateral offset enables the fingers of the user to be placed in position to exert a force substantially along the longitudinal axis (36) of the motor while engaging an ON/OFF trigger (46) of the joiner. In this manner a more direct application of force can be made by the user to the housing when urging the housing linearly while making plunge cuts with the joiner. The handle construction also provides the joiner with a well balanced, positive "feel"  and enables a wider variety of hand orientations to be used when operating the joiner. The joiner of the present invention is even more comfortable to operate than previously developed stick handle type joiners, even with the additional weight of the removable battery pack, and can therefore reduce the fatigue of the user's hands and arms when the joiner is operated over prolonged periods of time.
