Abstract: A coin dispenser in which cash of coins inside the machine and outside the machine is managed in a clearly distinguished manner and jamming of a coin can be easily eliminated in temporary suspension processing of the identification of a received coin when it is received. A partition frame (23) is arranged on the front side of a section (17) for accumulating and ejecting coins on a coin denomination basis, and a storage hopper section (13) and a coin identifying/sorting passage (15) are provided on the front face of the partition frame (23). The partition frame (23) can be switched between a position at which the section (17) is partitioned from the outside of the machine body (11) and an open position at which the section (17) is exposed to the outside of the machine body (11). A locking means (24) for locking the partition frame (23) at the partitioning position is provided. Coins located in the storage hopper section (13) region or the coin identifying/sorting passage (15) region can be freely operated, and coins in the accumulating/ejecting section (17) can be operated by unlocking the locking means (24) and opening the partition frame (23). Consequently, jamming of coins can be eliminated in the storage hopper section (13) region and the coin identifying/sorting passage (15) region.

IPC: C12Q1/00

Abstract: The present invention relates to a novel integrated PCR-free signal amplification polynucleotide detection system which combines a specific receptor, an optical transducer, and an amplification mechanism. This novel detection system is based on different electrostatic interactions and conformations between a cationic polythiophene (i.e. polymer 1) and single-stranded or double-stranded polynucleotides (such as ss-DNA or ds-DNA), and the efficient energy transfer between the triplex (complexation between the cationic polythiophene and ds-DNA) and neighboring fluorophores attached to ss-DNA or ds-DNA probes. It is to be understood that in the case of ss-DNA, triplex formation occurs via the hybridization of complementary ss-DNA  strands, combined with complexation with the cationic polythiophene. The present detection system allows for the detection of single nucleotide polymorphisms (SNPs) from samples in only a few minutes, without the need for nucleic acid amplification.

Abstract: The invention consists of a discontinuous helical auger contained within a waterless biotoilet. The auger enables thorough turning of sawdust enclosed within a heated drum.  Control of auger rotation works to maximize the biodegradation of human toilet waste through physical breakdown of organic matter, through stimulation of evaporation of the aqueous fraction, and through supporting a benign microflora to effect biodegradation. This discontinuous helical auger enables maintenance of a flat horizontal upper planar surface of the sawdust mass while maximizing aeration of the sawdust mass. The angle of the helical blade and discontinuities therein work to draw the organic matter very gradually toward the opposite end of the biotoilet from the toilet hole, maximizing dewatering and aerobic breakdown along the way.

Abstract: In a wireless local area network including an access controller (AC) and an access points (AP), the AC transmits a functionality inquiry to the AP. Upon receiving the inquiry, the AP transmits a query response including the functional capabilities of the AP. The AC then generates a map of the functional capabilities present in the network based on the inquiry response.  Conflicting or redundant functional capabilities are identified and are disabled, enabled, or reconfigured by instructions from the AC. The AC may selectively enable and/or disable functional capabilities at nodes in the network to provide a more balanced load on the network, and to provide for load sharing by allocating functionalities between and among network nodes having common functional capabilities to satisfy a variety of situations encountered in the network.

Abstract: Frequency segmentation is important to the quality of encoding spectral data.  Segmentation involves breaking the spectral data into units called sub-bands or vectors. Homogeneous segmentation may be suboptimal. Various features are described for providing spectral data intensity dependent segmentation. Finer segmentation is provided for regions of greater spectral variance and coarser segmentation is provided for more homogeneous regions. Sub-bands which have similar characteristics may be merged with very little effect on quality, whereas sub-bands with highly variable data may be better represented if a sub-band is split. Various methods are described for measuring tonality, energy, or shape of a sub-band. These various measurements are discussed in light of making decisions of when to split or merge sub-bands to provide variable frequency segmentation.

Title: Method and device for gravure printing using an erasable and re-usable printing form
Inventor: FUHRMANN HARTMUT
IPC: B41N1/06
Filed: 2006-10-27
Abstract: The invention relates to a method and a device for gravure printing using an erasable and re-usable printing form. The starting point of said method is a gravure printing form comprising a basic grid that is designed for the maximum quantity of ink that is transferred, said grid being uniformly filled in a filling process, a pattern being created by thermal ablation and the gravure printing form being erased after the printing process. The aim of the invention is to provide a method and device with which the complete removal of the filler material can be performed in a justifiable time in a reliable manner, even outside the printing press. To achieve this, the filler material and the residual ink is removed by a separate laser beam from that of the image-point transfer device.
