Abstract: Portable jobsite equipment includes a generator including an internal combustion engine and an alternator. The internal combustion engine includes a first cylinder including a first spark plug configured to create a first electrical spark, a second cylinder including a second spark plug configured to create a second electrical spark, an electronic control unit configured to activate and deactivate at least one of the first cylinder and the second cylinder, and a load source receiving supplied power from the generator. The electronic control unit activates one of the first cylinder and the second cylinder in response to a threshold increase of the load source.

Abstract: An apparatus including an internal combustion engine, an electric motor configured to start the internal combustion engine, a brake mechanism, a release mechanism movable to a first position to release the brake mechanism, a switch actuated by the release mechanism, a pull rope, a sensor configured to output a signal based on the pull rope being actuated, and a control module coupled to the switch and the sensor. The switch is configured to provide a switch input to the control module when the release mechanism is in the first position. The sensor is configured to provide a sensor input to the control module when the pull rope is actuated. The control module activates the electric motor in response to the switch input and the sensor input.

Abstract: An engine control system includes an engine, crankshaft, and a flywheel. The flywheel is coupled to the crankshaft of the engine and includes a number of magnets arranged axially along a first side. The system further includes a printed circuit board including a number of coils integrated into the circuit board. The printed circuit board is positioned such that a first face of the printed circuit board is positioned parallel to the first side of the flywheel. Power is generated by the flywheel rotating and causing the magnetic fields associated with the magnets to induce a current though the coils integrated into the printed circuit board.

Abstract: A self-contained starting module for outdoor power equipment that has control circuit and a start button. The starting module includes internal control circuit that can be either microprocessor based or analog. The control circuit receives a start signal from a start button of the starting module. The control circuit monitors for the presence of an enable device and, upon activation of the start button and the presence of the enable device, provides electric power to the electric load of the power equipment. When the start button is depressed for longer than a minimum engagement period, the control circuit initiates operation of the engine. If the start button is pressed for less than the minimum engagement period, the control circuit activates the electric load for an auxiliary period without starting the engine. During engine operation, if the start button is depressed, the operation of the engine is terminated.

Abstract: A battery pack for use to provide starting power of an internal combustion engine. The battery pack includes an outer housing that encloses a plurality of individual battery cells organized into two battery groups. A charging circuit is contained within the outer housing, which allows the battery cells to be recharged without the need for a charging device other than the battery pack. The charging circuit allows the battery cells to be recharged from either a wall outlet or from the alternator of the internal combustion engine. The battery pack further includes a switching circuit that can configure the battery groups in either a parallel mode or a series mode. In the series mode, the output voltage of the battery pack is increased for starting a cold engine. In the parallel mode, the amount of current available from the battery pack is increased.

Abstract: An engine control, communication and starting system for outdoor power equipment that has a controller and a one or more safety interlocks. The controller monitors the status of the safety interlocks to determine whether the internal combustion engine can be started upon activation of a starting device. If the starting device is activated and one or more of the safety interlocks is in a condition that prevents operation of the engine, the controller generates a feedback message to the operator through a feedback system. The feedback message can be either an audible or visual message that relays information to the operator. The system further includes a speed selection circuit that allows the operator to select the desired engine speed. The controller operates the internal combustion engine at the selected engine speed. During engine operation, the controller terminates operation of the engine if any of the safety interlocks move to an un-allowed status.

Abstract: A system and method is provided for synchronizing a data set across a distributed, electronic, health record system which includes creating and storing the data set at a first deployment, assigning a unique identifier to the data set, designating the first deployment as a home deployment for the data set, and transmitting a copy of the data set, the unique identifier, and the home deployment designation to a master index server. The method also includes causing the master file index server to transmit the copy of the data set, the unique identifier, and the home deployment designation to the second deployment if it is determined that the data set should be transmitted to the second deployment, and causing the master file index server to synchronize the data set between the first deployment and the second deployment.

Abstract: A system provides an information sharing architecture that allows physically separate healthcare information systems, called “deployments,” to share and exchange information. The collection of these participating deployments is referred to as the “Community,” and systems within the Community sometimes store records for patients in common. The system allows participants in the Community to share information on data changes to these patients, and to reconcile concurrent and conflicting updates to the patient's record.

Abstract: A power supply system includes a non-linear section that provides an intermediate voltage. A linear section receives the intermediate voltage and generates the output voltage. The linear section forms a control signal that is used by the non-linear section to change the value of the intermediate voltage as the output voltage changes to keep the differential voltage across the linear section low.

Abstract: A power supply system (10) includes a non-linear section (56,76) that provides an intermediate voltage. A linear section (57,63,64) receives the intermediate voltage and generates the output voltage. The linear section (57,63,64) forms a control signal that is used by the non-linear section (56,76) to change the value of the intermediate voltage as the output voltage changes to keep the differential voltage across the linear section (57,63,64) to the lowest and hence boost efficiency.
