  • Method and computer-readable medium for terminating options for dispatch group calls
    Patent number: 8306203
    Abstract: When an ad hoc group call is initiated, or at a subsequent time but before the group call is terminated, a call originator may set a parameter to establish a time limit. The time limit is invoked when the call originator drops from the group call. The time limit may be set to zero time indicating that all participants will be disconnected and the group call will be terminated immediately upon exit of the call originator. The time limit may also be set to a predetermined amount of time, which indicates that the group call may remain up until the predetermined amount of time expires. If no parameter to establish a time limit is selected, the group call may remain indefinitely even after the originator exits the group call.

  • Cell monitoring and balancing
    Patent number: 8274261
    Abstract: A method for monitoring the voltage of each of a plurality of cells of a battery pack is provided. The method may include monitoring a voltage potential for each of a plurality of cells in a battery pack utilizing a single channel of battery control unit within the battery pack. If, during discharge of the battery, e.g., the battery is being used to power a hand tool, the voltage potential of any cell is determined by the battery control unit to be below a predetermined minimum voltage, the battery control unit discontinues a current flow from battery pack to the tool. Additionally, during charging of the battery pack, if a voltage differential between any one of the cells and any other one of the cells is determined to be above a predetermined maximum differential, the battery control unit reduces the voltage potential stored in the cell having the higher voltage potential.

  • Earth-boring tools with improved retention of cutting elements installed within pockets
    Patent number: 8240403
    Abstract: A rock bit is formed with pockets for enhanced cutting element retention and support of cutting elements during operation of the rock bit. Portions of the pockets are carburized to increase a yield strength of the pockets, which also increases the retention of the cutting elements. The pockets are formed at a diameter that is slightly smaller than an outer diameter of the cutting elements. Portions of the pockets are then carburized. The pockets are heated until the diameter of the pockets is equal to the outer diameter of the cutting elements. After the rock bit has been cooled and cleaned, a material is placed in each pocket prior to installing the cutting elements. The material homogenizes support for the cutting elements during operation of the rock bit.
