Abstract: Various embodiments of a method and system for detecting unauthorized signatures to or from a local network. Multiple sensors are connected at an internetworking device, which can be a router or a switch. The sensors operate in parallel and each receives a portion of traffic through the internetworking device, at a session-based level or at a lower (packet-based) level. Depending on the type of internetworking device (router or switch) the load balancing mechanism that distributes the packets can be internal or external to the internetworking device. Also depending on the level of packet distribution (session-based or packet-based), the sensors share a network analyzer (if session-based) or both a network analyzer and a session analyzer (if packet-based).

Abstract: A computer system or other electronic system includes a plurality of cooling fans configured to operate in parallel. The cooling fans are operated in a manner to decrease the operating time of a fan. The cooling fans can alternate in operation. Thus, operating time is more equally divided between the two cooling fans and the hours of operation and number of rotations of the fans is more nearly equal. In an embodiment to reduce noise, two fans run at a lower speed instead of one fan at a higher speed. In an embodiment, a fan operates with a reduced speed which maintains a desired operating temperature. In an embodiment a thermal table is stored in BIOS (basic/input output system).

Abstract: The combining of two technically contrasting functions of “safe stopping” and “braking by armature short-circuiting” is served by using two means for pulse inhibition to block the respective current valves in the event of a fault by interrupting respective supply voltages for driving the control valves of the upper bridge arm and those of the lower bridge arm. For the purpose of braking by armature short-circuiting, the stator winding of a three-phase AC motor is short circuited in the event of a fault, or else operationally, by virtue of the fact that all current valves of a bridge arm can be switched on, a voltage being provided for switching on these current valves via a logic unit when the respective supply voltage for driving the current valves of this bridge arm are interrupted by the means for pulse inhibition.

Abstract: A wireless tire inflation pressure measurement device is used to obtain inflation pressure information for a tire of a vehicle and a signal therefrom may be used for determining the location of the tire. An identifier may be associated with the inflation pressure information for each wheel of the vehicle.

Differences in wheel rotation speeds during a turn may be used in determining the location of each tire of the vehicle. An antenna may be placed on each wheel toward the outer perimeter of the wheel and connected to the radio frequency transmitter. A radio frequency identification (RFID) tag and pressure sensor may be used as the wireless tire inflation pressure measurement device and a RFID pickup coil may be provided in each wheel well for pickup of the inflation pressure signals from each RFID tag on a wheel.
