Patent CA-2156000-A1 (CA)
Inventor: CHEN JUIN-HWEY
IPC: G10L19/00
Filed: 1995-08-14
Abstract: A method and apparatus for improving the performance of coding systems in the presence of frame erasures or lost packets. The encoded signal ismodified after transmission but prior to decoding by a decoder preprocessor. Thepreprocessor recognizes that a given frame has been corrupted and modifies the encoded signal so that the decoding thereof will result in improved coding system performance. Specifically, based on the decoding process and on a predetermined target signal, the encoded signal is modified so that the decoding thereof will generate an approximation to the target signal. In a first illustrative embodiment, a CELP speech coder is used and the target signal is an excitation signal comprised of all-zero excitation vectors. In this case, the portion of the corrupted excitation signal indices which identify the corresponding gain factors are set to values which represent a low gain factor. In a second illustrative embodiment, a CELP speech coder is used and the target signal comprises an extrapolation of the excitation signal represented by the encoded signal for one or more previous frames. In this case, the preprocessor encodes the extrapolated excitation signal using the best codebook matches available. In either case, the effect of corrupted frames in the reconstructed speech signal is minimized.

Title: Bar cleaner for trash bag breaker
Inventor: CAMPBELL RAYMOND W
IPC: B08B1/00
Filed: 1996-01-24
Abstract: A multiplicity of teeth are mounted to a beam in a comb structure, with the space between the teeth defining slots. The edges of the slots are lined with upstanding flanges which are sharpened to form cutting edges. The comb structure is arranged to be substantially parallel to an array of bag breaking bars. The bars interdigitate with the teeth and thus pass through the narrow openings between the teeth where the knife edges scrape the bars, thereby cutting free any material adhering to or impaled upon the bag breaking bars. Alternatively, an apparatus for cleaning a bag breaker has a pivotally mounted are having a fork which is aligned to receive a bar between the tines of the fork. The fork engages the base of the bar and then proceeds to slide up the bar as the forward motion of the bar causes the arm to pivot. In this way, material impaled upon a bar is slid or scraped upwardly towards the top of the bar. When the fork reaches the top of the bar and has thus removed any material impaled upon the bar, it pivots in response to an attached spring back to its initial position wherein it engages the next bar in sequence.

Patent CA-2175792-A1 (CA)
Inventor: PHAN DEAN VAN
IPC: A61F13/53
Filed: 1994-11-09
Abstract: A process for making an absorbent structure having a capillary substrate and regions of osmotic absorbent on the capillary substrate. The osmotic absorbent is cured from a liquid precursor applied to the capillary substrate. The capillary substrate has regions of topographically different elevations, taken normal to the plane of the capillary substrate. The capillary substrate is passed through a gap between a transfer roll and an anvil roll in a printing apparatus. The transfer roll has at liquid precursor on its periphery. The liquid precursor is applied to only the topographically elevated regions of the capillary substrate which contact the periphery of the transfer roll. By changing the topography of the capillary substrate, the liquid precursor can be applied to the capillary substrate in different pattern, without changing the transfer roll. This arrangement allows for absorbent structures having various patterns of osmotic absorbent on a capillary substrate to be readily produced with great flexibility in the manufacturing process.
