Filed: 1996-08-08
Abstract: A modulation method generates a rate 16/17 (d = 0, G = 7/I = 11) modulation code for transferring user digital data bytes having a three-way ECC interleave through a data transfer channel in accordance with the steps of: shuffling (112, 114) the user data bytes in order to rearrange an order of the bytes in a predetermined manner and putting out AiBi byte pairs, encoding (116) eight bits of the Ai bytes of the AiBi byte pairs in accordance with a predetermined rate 8/9 modulation code to produce nine code bits a0-a8, and interleaving (130) the nine code bits a0-a8 of each Ai byte with eight unencoded bits of each Bi byte in accordance with a predetermined bitwise interleave pattern to generate the rate 16/17 modulation code. A preferred code and circuitry for the modulation method are also described.

Title: Method for treatment of wood
Inventor: HELLGREN KEIJO
IPC: B27M1/02
Filed: 1996-12-20
Abstract: A method for treatment of one or more wood elements (4) by pressurization comprises the steps of embedding the wood elements into a pressure medium (8), of increasing the pressure in the pressure medium, whereby the wood element is compressed by transmitting the pressure via the pressure medium to the wood elements, and of reducing the pressure in the pressure medium, whereby the wood element is relieved. During the treatment, liquid present in the wood elements (4) is driven out therefrom. The pressure medium (8) comprises a plurality of solid bodies with intermediate spaces. The solid bodies transmit the pressure to the wood elements such that a pressure difference arises between the wood elements and said spaces, which pressure difference drives out the liquid. During the relief phase, the wood elements substantially resume their original shape. The method can also be used for introducing impregnating liquid into the wood elements after the liquid expulsion.

IPC: A47L5/38
Filed: 1998-09-08
Abstract: In a device known as central vacuum cleaning system, commonly a filter kown as self cleaning filter bag separates dust and debris from the air flow. This invention consists of solenoid slides that close the opening between the vacuum chamber section of what is known as "Power Unit" and the motor assembly above it, and at the same time open this vacuum chamber to the atmosphere when the motor is turned off. This sudden atmospheric pressure above the filter versus still existing vacuum below the filter pushes the filter bag rapidly down, shaking the dust and fine debris off the filter bag into a dirt receptacle below the filter.

Filed: 1998-01-22
Abstract: A digital waveform generator (10) reads out simulated .DELTA..SIGMA. ADC data (40) for a desired periodic analog waveform from a memory (38) and converts it, using a low-resolution high speed DAC (50), into a synthesized analog waveform (54). The .DELTA..SIGMA. digital waveform generator is preferably designed to take advantage of the natural evolution of device technologies.  The memory is fabricated with older technologies, which tend to be slower but have a much higher integration. The DAC is implemented in more recent technologies, which are faster but have less integration. A speed up buffer (44) or buffers in intermediate speed intermediate integration technologies may be included to provide a bridge between the low speed memory and the low integration DAC. As the current technologies become more well developed, and thus more integrated, and new higher speed technologies take their place, the technologies for the various components will gradually change, but the architecture should remain viable and superior to the known digital generators.
