摘要:
A method for operating a driving tool, such as a fastening tool, that has a driver, a motor assembly with a motor and an output member, and an electrical power source. The methodology includes transmitting electrical power to the motor to rotate the output member and thereafter adjusting one or more control parameters if a rotational speed of the output member is not within a predetermined operating range.

A power tool for operating on a workpiece, the power tool having a housing and a motor disposed within the housing. A controller is connected to the motor and receives user inputs for turning on the motor and a power tool battery pack is connected to the controller and the motor. At least one light is connected to the controller for illuminating the workpiece. The controller can turn on the light in a predetermined pattern to alert the user to a tool condition, such as the charge level being below a predetermined level.

A driving tool having a driver, a power source, a sensor and a controller. The power source selectively provides an input to the driver to cause the driver to translate along an axis. The sensor senses a condition in the power source that is indicative of a level of kinetic energy of an element in the power source and generates a sensor signal in response thereto. The controller is coupled to the power source and the sensor and is responsive to the sensor signal for deactivating the power source to inhibit the power source from providing the input to the driver when the level of kinetic energy of the element in the power source is below a predetermined threshold. A method for operating a driving tool is also provided.

A build system and method, including receiving attribute rules and new rules, wherein the attribute rules correspond to one or more predefined default actions of the build system, wherein the new rules specify new actions that are to be added to the build system. A graph is generated to include files specified as attributes in the attributes rules and the one or more predefined default actions that correspond to the attributes rules. A request to enable at least one of the new rules is received. Action listener rules are received, wherein the action listener rules indicate default actions and corresponding new rules of the one or more new rules. The graph is checked for default actions that are indicated in the action listener rules. Additional actions are added to the graph for new rules based on the default actions indicated in the action listener rules.

A portable electrical generator has a manually movable frame. An internal combustion engine and a generator device that generates AC power are supported on the frame. The internal combustion engine drives the generator device. An electrically powered starting device is coupled to the internal combustion engine. A control panel is coupled to the frame and includes at least one AC outlet and a battery receptacle that is electrically coupled to the starting device. The battery receptacle is materially the same as a foot of a cordless power tool that receives a battery pack. The battery pack for the cordless power tool is received in the battery receptacle and provides electrical power to the starting device. In another aspect, the battery receptacle is disposed in an enclosure supported by the frame. In an aspect, the enclosure further includes a battery charger. In an aspect, the enclosure also includes an AC outlet electrically coupled to the generator device with the charger being a stand alone charger plugged into the AC outlet of the enclosure. In an aspect, the battery receptacle receives a battery pack that is one of a plurality of battery packs having different voltages and the generator includes a voltage regulation circuit that couples the battery receptacle to the starting device. The voltage regulation circuit provides at an output coupled to the starting device a voltage at a desired level for the starting device regardless of the voltage of the battery pack received in the battery receptacle.

A gaming method is disclosed and comprises the following steps, which need not necessarily be performed in the exact order: providing at least two card representations to a player, each card representation comprising a symbol, the symbol having a corresponding predetermined value; providing at least two card representations to a dealer, each card representation comprising a symbol, the symbol having a corresponding predetermined value; evaluating a blackjack game outcome by comparing the values of the player and the dealer's card representations, wherein the player wins the blackjack game if the sum of the predetermined values of the player's card representations is higher than the dealer's; using two of the player's card representations for a game of poker; using two of the dealer's card representations for a game of poker; defining values for a plurality of combinations of two card representations; and evaluating a poker game outcome based on the player and the dealer's two card representations, wherein the player wins the poker game when the player possesses a two card combination that has a higher predetermined value than any of the dealer's two card combination.
摘要:
A generator system has two modes of operation, such as 120 VAC and 240/120 VAC. The generator system has a permanent magnet generator with two independent sets of windings that each generate a three phase AC voltage. One three phase AC voltage is coupled to a first cycloconverter and the second three phase AC voltage is coupled to a second cycloconverter. Live outputs of each cycloconverter are coupled to each other through a switch, such as a relay, and netural outputs of each cycloconverter are coupled to ground. A controller controls the cycloconverters to provide the modes of operation. In the 120 VAC mode, the switch across the live outputs of the first and second cycloconverters is closed, shorting the live outputs of the first and second cycloconverters together so that the live outputs are in parallel and the controller operates the first and second cycloconverters so their output voltages are in phase with each other. When in the 240/120 VAC mode, the switch across the live outputs of the first and second cycloconverters is open so that the live outputs are in series and the controller operates the first and second cycloconverters so that their output voltages are 180 degrees out of phase. The permanent magnet generator has rotor position sensors that are used by a DC motor drive to drive the generator as a brushless DC motor to start the engine of the generator system and also to develop cosine wave information for use in controlling the cycloconverters.
