Abstract: A power tool having multiple wireless communication states and a method of wirelessly communicating by a power tool. The power tool includes a motor, a battery pack interface that selectively receives a battery pack, a backup power source, and a wireless communication controller coupled to the backup power source and the battery pack interface. The wireless communication controller operates in a connectable state when coupled to a battery pack and transmits tool operational data to the external device and receives tool configuration data from the external device. The wireless communication controller operates in an advertisement state when the wireless communication controller is coupled to and powered by the backup power source. In the advertisement state, the wireless communication controller is configured to transmit the unique tool identifier. The external device may also display an indication of the communication state of the power tool.

Abstract: A power tool and method of detecting impacts of a power tool that includes a motor driving a hammer to impact an anvil. A motor control unit is configured to determine a motor characteristic indicative of a speed of the motor. When the motor characteristic indicates that the speed of the motor is below a speed threshold, the motor control unit employs an acceleration-based technique to detect a first impact based on a change in motor acceleration and generate a first impact indication in response to detecting the first impact. When the motor characteristic indicates that the speed is above the speed threshold, the motor control unit employs a time-based technique to detect a second impact based on an elapsed time and generates a second impact indication in response to detecting the second impact.

Abstract: To enable efficient processing of an insurance claim that is submitted by a client, the presently disclosed embodiments include systems and methods that enable an insurance computing system to autonomously assess the risk of fraud associated with a claim by generating a risk score. The risk score may provide an indication of a likelihood of fraud associated with the claim based on similar insurance claims in the same geographical area, client information indicative of a likelihood to commit fraud, and/or a type of the claim. The insurance computing system may compare the risk score with a threshold number, and if the threshold number is exceeded, the insurance computing system may prompt the client to contact a service representative to further process or validate the claim. Otherwise, if the threshold number is not exceeded, the insurance computing system may continue processing the claim autonomously.

Abstract: A method of calibrating a feedback-based noise cancellation system of an ear device may involve obtaining a measured plant response of the ear device, obtaining a reference plant response value and determining a plant response variation between the reference plant response value and a value corresponding to the measured plant response. The method may involve obtaining a measured a coupler response of the ear device, obtaining a reference coupler response value and determining a coupler response variation between the reference coupler response value and a value corresponding to the measured coupler response. The method may involve determining, based at least in part on the plant response variation and the coupler response variation, a microphone signal gain correction factor and applying the microphone signal gain correction factor to ear device microphone signals that are input to a feedback loop of the feedback-based noise cancellation system.

Abstract: An air suspension system which includes the ability to adjust the working air volume, pressure, and spring rate of one or more air springs to reduce or eliminate various types of vehicle oscillations. Switchable or variable volume air spring assemblies have the ability to change air spring volumes, which results in changes in air spring rates, and therefore changes in normal loads applied to each wheel. Changes in wheel normal loads change wheel traction (slip) and vehicle dynamics (pitch, roll, yaw displacement, rate and acceleration). The spring rate of one or more of the air spring assemblies is adjusted automatically when a vehicle oscillation is detected. This vehicle oscillation is calculated from the raw vehicle signals, or another vehicle module may detect the oscillation and send a command to the air suspension module to change the spring rates. This changes the natural frequency of the vehicle, dampening the oscillation.

Abstract: A hydraulic brake system for a vehicle which has expanded functionality, where a pre-charge occurs in the brake system upon deactivation of the cruise control, reducing the time needed to generate pressure in each brake unit, reducing stopping distance. The pre-charge function involves generating pressure in each caliper of the brake system upon deactivation of the cruise control function of the vehicle, such that the hydraulic brake system is pre-charged prior to the driver of the vehicle applying force to the brake pedal, which reduces stopping distance. One aspect of the pre-charge function includes generating enough pressure such that the brake pads contact each corresponding rotor. Another aspect of the pre-charge function includes generating enough pressure such that the brake pads apply force to each corresponding rotor, providing a minimum amount of deceleration prior to the driver of the vehicle applying force to the brake pedal.

Abstract: An air suspension system which includes a Dynamic Load Transfer (DLT) function. DLT is a process of transferring vehicle load, or varying normal loads applied to each wheel of the vehicle, using switchable volume or variable volume air spring assemblies. Switchable or variable volume air spring assemblies have the ability to change air spring volumes, which results in changes in air spring rates, which result in changes in normal loads applied to each wheel. Changes in wheel normal loads change wheel traction (slip) and vehicle dynamics (pitch, roll, yaw displacement, rate and acceleration). Each air spring assembly may have multiple volume air chambers that are switched “on” and “off,” a variable volume air chamber, or the air spring assembly may be coupled with other air springs, or air chambers, that are switched or varied.

Abstract: A method of controlling a transmission park control system for a vehicle comprises receiving a shift request from a transmission controller, wherein the shift request is not completed by the transmission and reporting the shift request from the transmission controller to the transmission park control system. Various vehicle sensors are monitored to detect motion of the vehicle. Detected motion and the shift request are compared to determine that a transmission park control brake action is desired. A brake system is requested to apply one of an electronic parking brake and/or a vehicle service brake to bring the vehicle velocity to zero and hold the vehicle velocity at zero.

Abstract: A vehicle stability control system operates by detecting a wheel speed potentially indicative of the presence of a mini-spare wheel at a wheel location of a vehicle with a wheel speed sensor and determines that a mini-spare tire is present responsive to the wheel speed remaining within a predefined band for predefined time. A threshold value that triggers action by a vehicle stability control system is adjusted to provide the mini-spare wheel with a value different than a wheel speed threshold value indicative of wheel slipping for a standard wheel.
