An off fire cooling system having an octagonal body shape and split fire system which doubles the coal heating surface area and doubles the coal heat output. The cooking system also has an air introduction system which circulates air throughout the interior of the grill to maintain an optimum cooking temperature. The octagonal maintains the cooking temperature at or above 400 degrees Fahrenheit in the center of the grilling system. The system eliminates grease fires and smoke associated with grease fire flare ups. The charcoal and food products are suspended for optimum cooking while preventing grease from falling onto the burning charcoal coals.

A method of detecting an effluent level in an aircraft lavatory holding tank and a device for practicing the method. The device uses electrodynamic forces of different values generated by an electro-impulse solenoid to determine whether a detector is contaminated, to dislodge contaminants, and to measure the fluid level in the holding tank when the detector is clean enough to produce an accurate reading.

Ice detection apparatus for use with aircraft having an EIDI solenoid mounted in proximity to the aircraft skin includes a current pulse generator selectively supplying the EIDI solenoid with current pulses of first and second levels, the second level being effective to generate force upon the skin to remove ice from the skin, and the first level being less than the second level. An accelerometer mounted on the interior surface of the skin produces an output signal in response to force imposed on the skin by current pulses of the first level. The output of the accelerometer is a function of both the current pulse level and of the presence of ice. A comparator is provided to generate an output signal indicative of the presence of ice when the accelerometer output signal reaches a predetermined level.

A passenger entertainment system having direct coupled individual seat receivers. Direct coupling of receivers to the passenger entertainment power and intelligence information signals is provided through a seat track transmission line consisting of one or more conductors associated with the seat track and running parallel to the seat track.

A method and apparatus for interconnecting passenger entertainment service units to the aircraft system through connectorless inductive couplers. Couplers are arranged along the seat track as desired without limitation on seat spacing or location.

A pulse height counter for counting the number of excursions of an incoming analog signal through each of a plurality of amplitude ranges. The pulse height counter automatically records not only the number of excursions through each amplitude level, but also records the number of amplitude excursions for each of a plurality of intervals. An analog input signal to be analyzed is synchronously applied to each of a plurality of comparators (VCO - VCF), which have reference voltages that are related so as to define predetermined amplitude ranges. During a count cycle, a counting circuit (CO - CF) receives the output signals from each of the comparators and produces a set of count data that indicates the number of occurrences of the analog input signal within each of the amplitude ranges. The count cycle is followed by a write cycle, during which the count values are stored in separate data bins, or event memories (MO - MF). The addresses of the memories are related to separate intervals during which count data for individual input signals can be stored. The addresses are shared by the memories so that, for a given interval, the count data for each of the amplitude ranges are stored at the same address but in a separate one of the memories. Thus, the count data for each of the amplitude ranges recorded during a predetermined interval may be recalled and displayed (18, 20, 22) during a readout mode of operation. The timing of the counting and writing cycles of operation is controlled by a count timer (32), a write timer (34), and an address counter (38) included in a timing and control circuit (10). Upon receipt of the analog input signal, the count timer is triggered to enable transfer of the outputs of the comparators to the counters. At the conclusion of the count cycle, the comparator outputs are disabled and the memories are enabled so that the count data may be transferred thereto. At the conclusion of the write cycle, the memories are disabled from receiving further count data and the counters are automatically reset so that new count data can be created upon receipt of a subsequent input signal. Substantially simultaneously with the resetting of the counters, the commonly shared address is incremented by 1 so that the count data for the next-received input signal is stored in the respective memories at the next successive storage location.
