Abstract: An apparatus and method for cleaning ash/soot and other particulates from diesel particulate filters (DPF), including diesel oxidative catalysts (DOC) and similar exhaust components. Section for dry and wet cleaning include conduits that connect to the filters. For dry cleaning, a filter is mounted clean side up and air pressure is applied in opposite directions so that the particulate is dislodged and falls out. For wet cleaning, the filter is floated with a slug of liquid cleaning solution which is surged back-and-forth through the filter to dislodge and remove the particulate. The dry and wet cleaning sections may be combined or collocated, or may be located separately or used one without the other.

Abstract: A method and system for printing comprises executing a formatter program on a removable Personal Computer (PC) card that controls printer controller functions of a printer. Printer formatter ready data is received from a host machine at a first interface of the removable PC card and print engine ready data is sent to the printer from a second interface of the removable PC card. A version of the formatter program is compared to a version of an updated formatter program. The updated formatter program is requested if the version of the formatter program is different than the version of the updated formatter program. The updated formatter program is downloaded from the host machine using the first interface when the second interface is coupled to the printer.

Abstract: The disclosure depicts both a system for operating an air conditioning compressor from alternative sources as well as a method of operating an air conditioning compressor from alternative sources. Both the system and method require a primary source, an air conditioning compressor, and a motor generator. A respective shaft extends from each of these required components, and a respective pulley is mounted to each of the respective shafts, and a single belt engages each respective pulley.

Abstract: Symbol sampling in a high time delay spread interference environment includes acquiring (602) a time varying baseband waveform. The waveform has a signal amplitude that varies between one of a plurality of symbol states. The waveform is sampled (603) at a rate of m times the symbol rate. During an evaluation time, an error value is calculated (604, 606) for each of m data sample positions. Each of the error values comprises an average distance between the measured value of the waveform as indicated by the data sample and a closest known symbol value. The error values are used to create an error surface. Thereafter, the error surface is modeled as a quadratic and an optimal sample time is determined (608, 610, 612) based on finding the time location where the quadratic surface is minimum. A sinc interpolator is then used to resample the data.

Abstract: A pulse width modulation technique is disclosed for use in an image forming device such as a laser printer or a photocopier. The technique implements a pacer to synthesize the frequency of a serializer circuit by stretching (or shrinking) pixel pulse train data. The pacer stretches the pixel pulse train data in accord with increment data that is based upon information about the image forming device, such as the number of bits in the pixel pulse train data, the number of bits in print engine pulse train, the target print engine frequency, and the serializer frequency. The technique can be implemented with digital circuits that provide digital test data.

Abstract: In a method of generating a fuser signal for a printer, a gating signal is generated using delta-sigma modulation such that an absolute value of a deficit does not exceed a threshold. The deficit corresponds to a difference between (i) a number of positive half-cycles of an alternating current (AC) signal at which the gating signal is high and (ii) a number of negative half-cycles of the AC signal at which the gating signal is high. The gating signal is used to gate the AC signal to a fuser.

Abstract: A demonstration system for a peripheral such as a printer connects an external, non-volatile memory to the printer in place of the host computer. One such peripheral uses a peripheral cable containing a controller or formatter that includes a computer interface for communications with the host computer and an interface for memory accesses. The peripheral cable connects to the computer interface for communications with the host computer. The demonstration system employs a controller or formatter of the same type as used in the peripheral cable and connects the interface for reading from the external memory. The controller can load both demonstration code and demonstration data from the external memory and direct the peripheral to perform a demonstration.
