The engine fuel metering system includes a fuel metering valve in flow communication with a fuel shutoff valve and a fuel bypass valve. The rotor protection system includes an overboost servovalve and a soleniod valve coupled to the fuel metering system and to an independent speed sensing system. In operation, servovalve can control the metered fuel flow to engine independently of the fuel metering valve to facilitate reducing rotor overspeeds and overboosts.

Abstract: An improved laser marking focal length setting device allows an operator of a laser marking apparatus to easily and properly set the distance between a movable laser source output and an item to be marked. The device includes a sensor which is mounted at the same distance from the item to be marked as the laser source output. The device further includes an array of light emitting diodes, each of which corresponds to a predetermined focal length. In operation, the laser source output and sensor are moved together along the axis of the laser beam. The sensor supplies a signal indicative of the distance between the sensor and item. Because the laser source output and sensor are located at the same distance from the item to be marked, this signal is also indicative of the distance from the laser source output to the item. When the distance sensed is a focal length corresponding to one of the LED's, that LED lights.

Abstract: An auxiliary canister operates with a storage canister of an evaporative emissions control system to reduce the amount of fuel vapor emitted from a vehicle to very low levels. The storage canister contains a first sorbent material and has a vent port in communication therewith. The auxiliary canister comprises an enclosure, first and second passages, a heater and a connector. Inside the enclosure, a second sorbent material is in thermal contact with the heater. Attached at one end to the bottom of the enclosure, the first passage is connectable at its other end to the vent port to allow flow between the storage and auxiliary canisters. Attached at one end to a top of the enclosure, the second passage is connectable at its other end to a vent valve of the control system to allow flow between the auxiliary canister and the vent valve. Incorporated into the enclosure, the connector is used to convey electrical power from the vehicle to the heater.

Abstract: A carrier-based signal is received from a tuner and is digitized to produce a digital intermediate frequency (IF) signal. Automatic gain control is applied to the carrier-based signal either prior to or after digitization. An adaptive intermediate frequency bandwidth control system detects IF signal level after channel filtering. The level is compared to a predetermined threshold having a value related to the known signal level of the AGC'ed signal which is being input to the channel filter in order to provide a measure of either 1) the presence of interfering adjacent channels, or 2) reception or a weak signal which can't be compensated for by AGC. The IF bandwidth is narrowed in either circumstance. Digital FIR or IIR filtering is used. The invention allows bandwidth switching to be done very quickly with minimal transient effects. A threshold value is selected depending upon the IF channel bandwidth being used at any given time.

Abstract: An adaptive intermediate frequency bandwidth control system detects IF signal levels both before and after channel filtering. The two levels are compared to provide a measure of the presence of interfering adjacent channels. This measure is compared to a programmable threshold and the IF bandwidth is narrowed if any interferers are detected. Digital FIR or IIR filtering is used. The invention allows bandwidth switching to be done very quickly with minimal transient effects. A difference threshold is selected depending upon the IF channel bandwidth being used at any given time.
