Using guard carriers for extra channels
To assist in minimizing interference, a bandwidth range can have guards on either side to reduce leakage into neighboring bandwidth ranges. However, in relatively low power situations the risk of leakage is reduced. Therefore, the guard bandwidths can be used to open new channels upon which information can be transmitted. Thus, there can be a larger amount of bandwidth used while still retaining protective aspects, such as low interference to neighboring bands. Using the guard bandwidth to transmit new channels facilitates backward compatibility since legacy devices do not commonly monitor the guard bandwidth. These techniques can also be used at high power base stations by advertising a larger guard than necessary to legacy devices and using the additionally created guard bandwidth to transmit new channels. |

Techniques are provided for distributed admission control (AC) in a mobile ad hoc network (MANET).

Protection apparatus of load circuit
A protection apparatus of a load circuit sets a threshold temperature at a lower temperature than an allowed temperature of an electric wire for use in the load circuit, and estimates a temperature of the electric wire based on an ambient temperature, a load current and a time while the load current is flowing through the electric wire. Then, in the case where the estimated temperature has reached the threshold temperature, a semiconductor relay (S1) is broken. As a result, in the case where such an electric wire temperature has risen owing to an occurrence of an overcurrent, and the like, the circuit is surely protected at the point of time before the electric wire temperature reaches the allowed temperature. Therefore, a fuse used in a conventional load circuit becomes unnecessary. |

Relay switching method and hybrid relay switch
A control system comprises a solid-state switch, a mechanical current interrupting device, and a control module. The solid-state switch is connected in series with a power source and an intake air heater. The mechanical current interrupting device is connected in series with the power source and the solid-state switch. The control module selectively closes the solid-state switch to provide power to the intake air heater. The control module also causes the mechanical current interrupting device to mechanically interrupt current flow to the intake air heater when a voltage of the intake air heater is outside of a desired range. |

Discharge device for vehicle
A discharge device for a vehicle includes a discharging circuit that connects a second capacitor and a discharging resistor in parallel through activation of a forced connection device. When a collision of the vehicle is detected, the discharge device forcibly stops electricity supply from the storage battery to the electric circuit including the second capacitor, and activates the forced connection device to forcibly discharge the second capacitor. A pair of connecting terminals of the forced connection device are arranged to be pressed against each other with an insulating member disposed therebetween. The forced connection device includes a gas generator for generating combustion gas directed to the insulating member. When an abnormality is detected, the forced connection device short-circuits the connecting terminals with each other through activation of the gas generator. The second capacitor and the discharge device are provided integrally. |

Electromagnetic heads, flexures, gimbals and actuators formed on and from a wafer substrate
Devices for reading or writing electromagnetic information include a wafer substrate piece disposed between an electromagnetic transducer and an electrostrictive or piezoelectric actuator. The substrate piece is shaped as a rigid body adjoining the transducer and as a flexible element connecting the body and the actuator. To fabricate, at least one electrostrictive layer and many transducers are formed on opposite sides of a wafer that is then cut into rows containing plural transducers. The rows are processed from directions generally normal to the wafer surface upon which the transducers were formed, by removing material to form a head, flexures and a media-facing surface on the head. Conductive leads are formed on a back surface of flexures connecting the transducer with drive electronics. The flexures are aligned with forces arising from interaction with the media surface and from seeking various tracks, reducing torque and dynamic instabilities and increasing actuator access time. |
