Title: Method for the detection of cytosine methylations in dna with the aid of scorpion primers
Inventor: TETZNER REIMO
IPC: C12Q1/68
Filed: 2004-08-13
Abstract: The invention relates to a method for analyzing cytosine methylations in DNA  sequences, according to which non-methylated cytosines are first converted into uracil while 5-methylcytosine remains unmodified. The DNA is then amplified by means of a polymerase and at least one primer whose 5 end is connected to a probe via a linker. The probe is intramolecularly hybridized onto the amplified products in accordance with the methylation state of the DNA, hybridization being detectable via different detection systems. The inventive method is particularly suitable for diagnosing and predicting cancer diseases and other diseases associated with a modification of the methylation state as well as for predicting undesired effects of medicaments.

Title: Combination gravimetric and volumetric dispenser for multiple fluids
Inventor: REMMERLHART DONALD A
IPC: B01F15/02
Filed: 2004-10-12
Abstract: A combination gravimetric and volumetric fluid dispenser is disclosed which includes a scale (15) linked to a controller (21). The controllar is linked to a plurality of two stage valves (14) which control the dispensing of larga quantities of base materials. The controllar is also linked to a plurality of nutating pumps (34) which together with the controllar controls the dispensing of smallar quantities of additive materials. The dispensing system dioclosed is particularly useful for paints or other liquid formulations where larger quantities of base materials are added and which can be added br weight and whereby precise measurements of the larger base materials is not particularly required. However, the incorporation of nutating pumps and the addition of smallar amounts of additives by volume using the nutatïng pumps enables precise dispensing of the additives, such as colorants for paint. The larger containers or reservoirs of base material may be disposed at a remote location from the dispensing apparatus. The dispensing apparatus is also preferably designed with a modular configuration as shown and described. For viscous materials, an improved dispensing rnethod is disclosed whereby viscous base material is added to the container first followed by smaller amounts of additives followed by additional dispensing of viscous base materials. By sandwiching the smallar amounts of additives between layers of base materials, an improved mix ability results for viscous materials such as base materials of paints and colorants.

Title: Overcomplete basis transform-based motion residual frame coding method and apparatus for video compression
Inventor: SAUER MARK
IPC: H04N19/61
Filed: 2004-03-29
Abstract: The present invention provides a method to compress digital moving pictures or video signals based on an overcomplete basis transform using a modified Matching Pursuit algorithm. More particularly, this invention focuses on the efficient coding of the motion residual image, which is generated by the process of motion estimation and compensation. A residual energy segmentation algorithm (RESA) can be used to obtain an initial estimate of the shape and position of high-energy regions in the residual image. A progressive elimination algorithm (PEA) can be used to reduce the number of matching evaluations in the matching pursuits process. RESA and PEA can speed up the encoder by many times for finding the matched basis from the pre-specified overcomplete basis dictionary. Three parameters of the matched pattern form an atom, which defines the index into the dictionary and the position of the selected basis, as well as the inner product between the chosen basis pattern and the residual signal. The present invention provides a new atom position coding method using quad tree like techniques and a new atom modulus quantization scheme. A simple and efficient adaptive mechanism is provided for the quantization and position coding design to allow a system according to the present invention to operate properly in low, medium and high bit rate situations. These new algorithm components can result in a faster encoding process and improved compression performance over previous matching pursuit based video coders.

Patent CA-2585537-A1 (CA)
Inventor: KOHLI MARKUS
IPC: G01N21/61
Filed: 2007-04-20
Abstract: The invention proposes a method for etalon suppression in a gas detection device by determining an etalon fringe period during a calibration step without gas in dependency of the DC drive current. A measuring signal which is a function of the gas absorption and substantially independent of an intensity modulation of an initial light signal at an initial frequency (f) is generated by determining a first pre-measuring signal when the laser source is operated at the center of the gas absorption peak, a second pre-measuring signal when the laser source is operated with a DC drive current below the gas absorption peak of the gas to be detected, and a third pre-measuring signal when the laser source is operated with a DC drive current above said gas absorption peak, with a difference between said DC drive currents which corresponds to the etalon fringe period determined in a calibration step before. The final measuring signal is determined as the difference between the first pre-measuring signal and the arithmetic mean of the second pre-measuring signal and the third pre-measuring signal. This etalon fringe suppression allows to implement a substantial simplification of a reference channel in a gas detector, which does not require separate lock-in channels which analyse the detector signal either on the modulation frequency (f), or on twice the modulation frequency (2f).

Title: Closed-loop rate control for a mimo communication system
Inventor: WALTON JAY RODNEY
IPC: H04J99/00
Filed: 2005-11-16
Abstract: In a MIMO system, rate control is achieved with an inner loop that selects rates for data streams sent via a MIMO channel and an outer loop that regulates the operation of the inner loop. For the inner loop, SNR estimates are obtained for each data stream based on received pilot symbols and/or received data symbols. An effective SNR is derived for each data stream based on the SNR estimates, a diversity order, a MIMO backoff factor, and an outer loop backoff factor for the data stream. The rates are then selected for the data streams based on the effective SNRs for the data streams. The outer loop adjusts the outer loop backoff factor for each data stream based on the performance (e.g., packet errors and/or decoder metrics) for the data stream.
