  • Patent number: 8264381
    Abstract: Architecture for enabling continuous operation of a control command issued by a control input (e.g., a control key on a computer keyboard or game controller). For example, for a user of a software application (e.g., a gaming application), an activation modifier is used for enabling continuous operation of the control command. The activation modifier can be a lock key or other type of input used in combination with the control key. During continuous operation of the control command, one or more alternate control inputs (e.g., from alternate control keys) are enabled to concurrently issue alternate control commands to the software application.

  • Patent number: 8259421
    Abstract: The voltage of a detection resistor connected to the drain of a low-side switching device is normally a negative voltage, but a positive voltage appears when a countercurrent occurs in an abnormal state. A current comparator monitors the voltage of the detection resistor, transmits high output to an AND circuit whole the voltage of the detection resistor is a negative voltage to maintain the output voltage of the current comparator in a low state when an output signal of a driver can be transmitted to the low-side switching device, and allows the output voltage of the current comparator in a low state when the voltage of the detection resistor becomes a positive voltage, thereby forcibly turning off the low-side switching device.
