Abstract: A system and method for monitoring the activity of a mobile subscriber in a GSM-based PLMN system (1150) from an Intelligent Network (IN) telecommunications system comprising several Intelligent Peripherals (IPs) (1111-1114) connected to a Service Control Point (SCP) (1101) over a network. The detailed technique is automatically initiated when the Service Control Point (SCP) (1101) of an IN system attempts to reach a mobile subscriber and fails. In the first phase, the SCP (1101) arms an SMS-IP (1114) using a dummy SMS message (1181). Upon the detection of renewed subscriber activity of a mobile subscriber (1165) who was previously inactive or unreachable, a PLMN triggering notification is generated. In this second phase, the PLMN (1150) transmits an alert (1183) to the SMS-IP (1114) which in turn notifies the SCP (1101).

Title: Method and apparatus for noise reduction, particularly in hearing aids
Inventor: BRENNAN ROBERT
IPC: H04R25/00
Filed: 1998-04-16
Granted: 2005-01-04
Abstract: This invention describes a practical application of noise reduction in heari ng aids. Although listening in noisy conditions is difficult for persons with normal hearing, hearing impaired individuals are at a considerable further disadvantage. Under light noise conditions, conventional hearing aids amplify the input signal sufficiently to overcome the hearing loss. For a typical sloping hearing loss where there is a loss in high frequency hearing sensitivity, the amount of boost (or gai n) rises with frequency. Most frequently, the loss in sensitivity is only for low-level signals; high level signals are affective minimally or not at all. A compression hearing aid is able to compensate by automatically lowering the gain as the input signal level rises. This compression action is usually compromised under noisy conditions. In general, hearing aids are of lesser benefit under nosiy conditions since both noise and speech are boosted together when what is really required is a reduction of the noise relative to the speech. A noise reducti on algorithm with the dual purpose of enhancing speech relative to noise and also providing a relatively clean signal for the compression circuitry is described.

Title: Solid imaging process using component homogenization
Inventor: LAWTON JOHN A
IPC: B22F1/12
Filed: 1998-04-28
Granted: 2007-09-04
Abstract: Solid objects are formed in an imagewise layering process in which components of a dispersion (105) are homogenized to form an alloy. Imagewise exposure of the layers to radiation to form an alloy permits separation of the exposed, homogenized regions (108, 108') from non-exposed, non-homogenized regions. As each layer is formed and imagewise homogenized, contiguous layer regions (109, 109') are bonded together to form a homogenized, three-dimensional object which may be separated from surrounding dispersion (105).
Patent CA-2290185-C (CA)

Filed: 1999-11-22
Granted: 2005-09-20
Abstract: Systems and methods for processing acoustic speech signals which utilize the wavelet transform (and alternatively, the Fourier transform) as a fundamental tool.  The method essentially involves "synchrosqueezing" spectral component data obtained by performing a wavelet transform (or Fourier transform) on digitized speech signals. In one aspect, spectral components of the synchrosqueezed plane are dynamically tracked via a K-means clustering algorithm. The amplitude, frequency and bandwidth of each of the; components are, thus, extracted. The cepstrum generated from this information is referred to as "K-mean Wastrum." In another aspect, the result of the K-mean clustering process is further processed to limit the set of primary components to formants. The resulting features are referred to as "formant-based wastrum." Formants are interpolated in unvoiced regions and the contribution of unvoiced turbulent part of the spectrum are added. This method requires adequate formant tracking. The resulting robust formant extraction has a number of applications in speech processing and analysis including vocal tract normalization.

Title: Method for separating co2 from waste gases, converting it to ch4 and storing both outside the atmosphere and methane produced by this method
Inventor: WILD WERNER
IPC: C12P5/02
Filed: 1999-12-13
Granted: 2007-12-11
Abstract: The CO2 is separated from waste gases by known technical means and stored in the underground (see drawing). By additions to the CO2, according to the invention, of H2 or NH3, methano-genic bacteria, bacteria substrate, catalysators and/or inhibitors the CO2 is reduced during the underground sto-rage to CH4. The storage is possible in aquifers, natural gas reservoirs or oil and/or gas generating rock formations. Due to the equal volumes of CO2 and CH4 the process is a closed cycle and of constant pressure. Natural gas becomes a renewable energy.

Abstract: An amplifier arrangement for amplifying an input (20) uses a distorting main power amplifier (14) such as one operating as a class AB amplifier. A predistortion signal is added to the input signal to compensate for the distortion added by the main power amplifier (14).

A digitally controlled processor (90) iteratively modifies various phase and gain controls to adjust the output of the amplifier. Different gain and phase control lines are iteratively updated at different rates.

Abstract: A control device detects a characteristic change of an air-fuel ratio sensor indicative of deterioration of the air-fuel ratio sensor. The control device determines deterioration due to aging of the air-fuel ratio sensor accurately and calculates an air-fuel ratio from the air-fuel ratio sensor highly accurately. Then, the control device detects a current proportional to the concentration of oxygen in the detected gas from a sensor element by applying a voltage to the sensor element of the air-fuel ratio sensor. By applying AC voltages at high and low frequencies to the element, an AC impedance is detected.      The temperature of the element is controlled to a target temperature according to the high frequency impedance and a characteristic change of the element is detected in accordance with the low frequency impedance.

Abstract: A camera dolly (30) has a steering system (50) which provides conventional, crab, and round steering modes, selected by the operator via use of a single steering/shifting handle (44). The steering system (50) includes first (102) and second (104) transmissions and a differential (108).      Chains (80, 82, 84, 86, 88, 92, 94) link sprockets on the transmissions and differential, to steer the wheels (45) of the camera dolly to appropriate angles, so that the dolly can roll easily and without wheel scrubbing. A dolly leg position compensator (300) adjusts the amount of steering angle correction provided by the differential, to compensate for changes in the dolly wheelbase/tread dimensions. Sprockets in the differential (108) are locked intop offset positions, during conventional and round steering, to maintain proper steering angle correction, even under heavy loads. Active idlers (75, 76, 77, 99) are mechanically linked within the steering system to automatically maintain appropriate chain tension, in all steering modes.
