  • Patent number: 12101051
    Abstract: The present invention relates to a method of commutation control of a brushless DC (BLDC) motor. The method uses a controller to control the BLDC motor using a modified six-step commutation. The method adds six intermediate steps that overlap the six-step commutation. Each of the six steps overlap with preceding and following steps, resulting in six additional intermediate steps in which all three phases are active. By doubling the number of steps, current and torque will vary less over time compared with current solutions without increasing the size or changing the design of the motor.

  • Publication number: 20240308036
    Abstract: A flex joint headed tool with a locking mechanism adapted to selectively retain the angle of the head relative to a handle. The locking mechanism may retain the head in at least one of two positions using a bias member and two detent balls disposed at opposite ends of the bias member. The bias member and detent balls may be disposed in a through hole disposed in a locking lever, with one detent ball engaging a joint tang and the other detent ball engaging a detent disposed in a tool body or handle, wherein the detent balls provide tactile response to a user. The locking lever may rotate between locked and unlocked positions, whereby in the locked position, the ratchet head is prevented from rotating relative to the handle, and when in the unlocked position, the head may rotate relative to the handle.

  • Patent number: 12090606
    Abstract: The present invention relates to a motorized hand tool having a motor with a motor front casing adapted to resist rotation of the motor with respect to a housing of the tool, without use of extra fasteners or machining operations. The motor front casing includes first and second flanges and first and second tabs that protrude radially outwardly and that are disposed proximal to respective ends of the flanges. When the motor is installed, the tabs abut a ratchet head housing and are sandwiched between the ratchet head housing and a rib if a tool housing to resist motor rotation and ensure all forces are distributed across a whole face of the rib to minimize deformation of the rib and/or tool housing.

  • Patent number: 12095402
    Abstract: The present invention relates broadly to commutation control of a BLDC motor for use with, for example, a power tool. The method uses a controller to control a BLDC motor in the event of a position sensor failure. Rather than ceasing operation of the motor and indicating a fault or error message to the user, the present invention determines when the next transition should occur based on the time between past hall transitions using a timer. Thus, if one or two position sensors are no longer providing position information to the controller, the controller can determine when the transitions would be changing based on past transitions to continue controlling the motor and prevents the motor from ceasing operation.

  • Patent number: 12095255
    Abstract: Overcurrent protection of an electrically powered, motorized device, such as a power tool, wherein the tool includes a tool housing, an output assembly, a trigger, an electrical safety device, a motor, an indicator, a controller, and a power source. The electrical safety device, for example a fuse, is disposed in series with a power connection from the power source to the controller. The controller measures current passing through the electrical safety device in time intervals when the trigger is actuated. The controller determines accumulated thermal energy passing through the electrical safety device, and compares the accumulated thermal energy to a threshold. If the accumulated thermal energy exceeds the threshold, the controller ceases or discontinues to allow power to be provided to the motor from the power source, thereby shutting off the motor. The controller may also activate the indicator to indicate a fault to the user.

  • Patent number: 12077045
    Abstract: A method includes writing vehicle data parameters (VDPs) into a memory in order of a vehicle outputting the VDPs. The method also includes displaying a first view of a graphical user interface (GUI) on a display. The GUI includes one or more VDP graphs, a graph-axis control, and a first vehicle operating condition (VOC) indicator at the graph-axis control. The method also includes displaying a second view of the GUI on the display in response to a selection of the first VOC indicator. The first and second views include first and second sets of VDP graphs, respectively. The second set of VDP graphs includes VDPs not represented in the first set of VDP graphs. Graph-axis control segments within the graph-axis control in the first and second views cover different portions of the graph-axis control. The graph-axis control segments correspond to different portions of the VDPs written into the memory.

  • Patent number: 12062021
    Abstract: A method and system for generating and outputting a real-fix tip (RFT) augmented with a pointer to additional content. The additional content may be relevant to any of a complaint, vehicle, cause of complaint, how the cause for complaint was discovered, and service-operation performed on the vehicle to resolve the complaint. The RFT may include a complaint, cause, and correction, and may be stored within a database containing repair orders that include complaints, causes, and corrections regarding various vehicles. A processor may generate the RFT after determining a threshold number of RO with a common complaint, vehicle, cause, and correction. A processor may search the database for the RFT based on a complaint and vehicle, display a list of RFT located during the search, display an RFT selected from the list, obtain additional content pointed to by a pointer in the RFT, and output the additional content to a display.
