Patent CA-2357491-A1 (CA)
Inventor: DEVRIES CHRISTOPHER ANDREW
IPC: H03H11/12
Filed: 2001-09-17
Abstract: A Method for filter tuning using direct digital sub-sampling is taught herein.  The tuning is accomplished in the digital domain by determining the filter characteristics from the shape of the transfer function. The input signal (1) is passed through the filter (3) and is then sub-sampled by and Analog to Digital Converter (ADC) (5). The sub-sampled signal (6) is then processed in the digital domain using a digital circuit (7) that is used to determine the center frequency (Fc) and Quality factor (Q) and/or other important filter parameters. The Fc, Q and/or other important filter parameters are then adjusted by generating digital control signals (8) that can be converted to analog signals (10) using Digital to Analog Converters (DACs) (9). This is a form of direct tuning as the filter itself is tuned without the use of a master filter or Voltage Controlled Oscillator (VCO). The tuning of the filter requires the digitization of the filter output (4).  The filter amplifies and shapes the input signal and noise to the filter transfer function. To facilitate tuning, the input signal may be attenuated during the tuning cycle. This can be accomplished by lowering the AMPlifier (2) gain and/or using an input switch that provides isolation between the input signal and the filter. The resulting frequency shaping by the filter may be amplified during tuning to give sufficient Signal to Noise Ration (SNR) in the ADC so that the shape can be resolved in the digital circuit.

Title: Packet shaping on a fixed segment scheduler
Inventor: JANOSKA MARK WILLIAM
IPC: H04L12/863
Filed: 2001-10-05
Abstract: Methods and devices for scheduling data transmission processing based on the size of the data transmission unit and a predetermined increment value.      A scheduler has slots which represent specific amounts of time in which a queue of data transmission units to be processed is represented. An indicator determines which slot and thereby which queue is being examined.      Each queue is assigned a specific increment value and each data transmission unit in a queue is assigned a count value based on the size of the data transmission unit. When a data transmission unit is at the head of the queue and is a candidate for processing, if the count value is greater than a predetermined value then the queue and thereby the data transmission unit at the head of the queue is rescheduled at a later time. This is effected by assigning the queue to a subsequent slot in the scheduler. The subsequent slot in the scheduler is determined based on the given increment value for that queue. The increment value is based on how many data transmission units are desired to be processed within a given amount of time.

Title: Method for preparing melamine
Inventor: TJIOE TJAY TJIEN
IPC: C07D251/60
Filed: 2000-03-02
Abstract: Method for preparing melamine from urea via a high-pressure process in which solid melamine is obtained by transferring the melamine melt to an expansion vessel where the melamine melt is cooled by incorporated ammonia. Excess ammonia gas is added to the melamine melt to produce a gas/liquid mixture having a mass ratio of at least 0.01. This two-phase mixture is then sprayed via a spraying means into an expansion vessel, the expansion vessel having an ammonia environment with a reduced ammonia pressure. The melamine melt is cooled and solidified by the expansion and evaporation of the incorporated ammonia to form melamine powder. The melamine melt is thereby directly converted into a melamine powder after which the melamine powder is cooled further and the ammonia pressure is released.
