Abstract: The electrical generator set has two separate cooling airflows. A first airflow is generated by an impeller mounted on the drive shaft of the engine and provides for cooling the electrical generator or alternator and for partial cooling of the electrical circuitry which controls mainly the voltage of the electrical output. This airflow exists only while the engine is running. The first airflow is mixed with the exhaust gases of the internal combustion engine for noise and temperature reduction. the use of a venturi tube supports driven by the exhaust gases supports the airflow.A second airflow provides for cooling the radiator of the liquid cooled internal combustion engine and for partial cooling for the electrical circuitry. This second airflow is generated by one or more electrical fans and is independent on whether or not the engine is running.

Abstract: A safety device and an alarm system controller of a workspace providing bidirectional communication for determining whether the required safety devices are used by the work persons entering the workspace, and whether the safety devices are properly worn. The communication means used allow to associate one or more safety devices to a work person.

Abstract: Installing a high quality audio source, such as a CD player, in an automobil requires often installation of a radio/tuner of sufficient quality to provide an audio signal corresponding to the quality of the audio source. In leased automobils this presents a problem because of warrenty and return conditions. The problem is solved by using a separate amplifier connected into the wiring between factory installed radio/tuner and loudspeakers and sensing the setting of the radio/tuner control knobs by placing a defined modulated carrier on the antenna input of the radio/tuner. The output of the radio/tuner then provides a signal reflecting the setting of the control knobs. This signal is used to control the amplifier.

Abstract: A method is provided for identifying, correcting, modifying and reporting imperfections and features in pixel images that prevent or hinder proper OCR (Optical Character Recognition) and other document imaging processes. One embodiment of this invention provides that run length compressed images can be analyzed and corrected directly for improved performance. Major steps included in this invention for the enhancement of images for OCR and document imaging are: The detection of undesired printed matter and the deletion of undesired printed matter. Detection of undesired printed matter includes successive generation of entries into an array listing of undesired printed matter to be deleted. Deletion of undesired printed matter follows in a separate step for all types of undesired printed matter.

Abstract: The compact electrical generator sets have separate cooling airflows for the cylinder of the driving internal combustion engine, for the electrical generator, and for the components which generate most of the heat. Providing separate airflows allows to reduce the size of the generator set. Use of an alternator and an electronic controller for converting the electrical energy generated by the alternator to electrical energy of the type required by the user simplifies the design. The design of the cooling airflow with multiple combined and separated airflows reduces both size of the generator set and reduces losses due to generating the airflows.

The so oriented magnetic particles retain their position when the external field ie removed, thereby storing the recorded information in the form of the figures and symbols. A portable apparatus includes electrically controllable write magnets for writing the figures and symbols, and an electrically controllable erase magnet for erasing previously recorded figures and symbols. The controllable magnets are mounted in a write/erase head which is self-adapting to the surface of the label.

Abstract: For performing optical character recognition and other scanned document image processing the method for unshading dot shaded areas performs a statistical dot size analysis to determine the distribution of the dot sizes in the dot shaded area. In a separate step the most suitable dot size limitation is determined, followed by deleting dots falling within the so determined dot size limitation.

Abstract: Synchronization with a signal derived from code violations in periodic data block preambles, and derived using analog circuits provides for a very low jitter clock. The method involves detecting the amplitude of an analog signal derived from the preamble. The amplitude exceeds a preset value whenever a code violation is detected. The frequency of the preamble may be a fraction or a multiple of the synchronized clock.

Abstract: In a run-length coded document image process a horizontal line in textual matter is eliminated by establishing a work zone around the horizontal line and a buffer zone of predetermined width around the work zone. All black-run-length artifacts that extend outside of the buffer zone are protected, this includes protecting information in the work zone when there is a matching artifact in the opposing buffer zone (Character Reconstruction). All black items that are within the work zone and the buffer zone, and which are not protected are eliminated.
