Title: Double-chamber ampoule
Inventor: HANSEN BERND
IPC: B65D1/09
Filed: 2005-07-26
Abstract: The invention relates to a receptacle comprised of an elastically flexible plastic material, comprising a dosing chamber (10), inside of which a medium to be discharged is located. One end of the dosing chamber (10) has a discharge opening (18), and the opposite end is connected via a junction point (20) to a compressible receptacle part (22) inside of which an, in particular, gaseous propelling medium is located. When compressing the receptacle part (22), the propelling medium forces, at least in part, the medium to be discharged out of the dosing chamber (10) via the discharge opening (18). An increased functional reliability in every application is ensured by virtue of the fact that the junction point (20) between the dosing chamber (10) and the receptacle part (22) is formed by a bottleneck provided for creating a capillary effect that, independent of the spatial position of the receptacle, prevents a transfer of the medium to be discharged from the dosing chamber (10) into the receptacle part (22) containing the propelling medium.

Title: Using orthogonal waveforms to enable multiple transmitters to share a single cdm channel
Inventor: AGRAWAL AVNEESH
IPC: H04W72/04
Filed: 1997-04-01
Abstract: A system and method for enabling multiple transmitters (400) to share a single code division multiplexed (CDM) or code division multiple access (CDMA) channel using orthogonal waveforms. A set of orthogonal channelizing codes Wi(t) is generated, and each transmitter (400) is allocated orthogonal channelizing codes and pseudonoise polynomials in a predetermined manner. The transmitters channelize each user signal using an orthogonal channelizing code Wi(t), and spread each user signal using a pseudonoise (PN) spreading code. Each transmitter employs the same PN spreading codes and time offsets. Additionally, no one orthogonal channelizing code is assigned to more than one transmitter during the time period they are sharing a CDM channel. The spread signals are summed at each transmitter (404) prior to transmission as a composite signal. The offsets are time- precorrected (406, 510) to ensure time alignment at the receivers. The frequencies of the signals are precorrected (408, 512) to ensure frequency alignment at the receivers.

Title: Determining modulo count in sleep capable system
Inventor: COUSINEAU KEVIN STUART
IPC: H04W52/02
Filed: 2006-03-10
Abstract: Apparatus and methods of determining a modulo count of a synchronization number in a sleep capable system. The synchronization number is stored in a comparison register, and a comparison number equal to the largest power of two multiple of the modulus within a predetermined range is subtracted from the synchronization number. If the difference is zero, the difference is stored in the comparison register, replacing the previous number stored in the register. If the difference is less than zero, the number stored in the register remains unchanged. The comparison number is right shifted, resulting in division by two. The process is repeated for a number of loops equal to the power of two, or until the difference is less than the modulus.

Title: Channel estimation enhanced lms equalizer
Inventor: PIETRASKI PHILIP J
IPC: H04L27/01
Filed: 2006-03-16
Abstract: The present invention is related to an enhanced equalizer using channel estimation. A scaled version of a channel estimate is used as an expected average behavior of the product of a transmitted signal and a received signal to implement Griffith algorithm. The present invention also uses advance or prediction of a channel estimate to overcome the lag problem inherent in a least means square (LMS) algorithm in a time varying channel. Therefore, the present invention enables the use of a small step size while attaining the same tracking capability with a large step size. A channel estimate at some time in the future is used for updating equalizer filter tap coefficients. This may be performed with a prediction filter. Alternatively, a delay may be introduced in the input data to the filter tap coefficient generator, which makes a channel estimate look like a prediction to the filter tap coefficient generator.

Title: Direct stream digital audio with minimal storage requirement
Inventor: JANSSEN ERWIN
IPC: G10L19/16
Filed: 2006-05-16
Abstract: An audio coding scheme allowing PCM signal to lossless DSD signal expansion for next generation optical disc formats. The method of encoding an input DSD signal includes up-sampling a corresponding PCM signal to the DSD sample rate. Then a set of loop filter parameters for a noise-shaping loop of a sigma-delta modulator are generated, either using a random starting condition of the sigma-delta modulator or including synchronization parameters. This will allow a decoder to regenerate an almost perfect signal, but still it needs a correction signal to be able to bit identically regenerate the DSD input signal. Therefore, a correction signal is generated based on a difference between a sigma-delta modulated version of the up-sampled PCM signal and the input DSD signal, wherein the sigma-delta modulated version of the up-sampled PCM signal is obtained using the set of loop filter parameters. The correction signal may be adapted to be applied to the low bit PCM signal, to the up-sampled PCM signal or to the output bit stream. Finally, an expansion bit stream is generated where an encoded version of the set of loop filter parameters and an encoded version of the correction signal are included. The decoder can reproduce the original DSD signal based on the already available PCM signal and the described expansion bit stream. Thus, the coding scheme enables top quality audio with minimal storage overhead since the already available PCM signal is used in combination with an expansion bit stream. Since only an additional data stream is required to be stored on a disc, e.g. as part of an MPEG stream, DSD functionality is added to existing systems without causing compatibility problems.
