Abstract: A forward error correction (FEC) method is provided that operates in a multiple access format, such as, e.g., a Time Division Multiple Access (TDMA) format. An FEC transband central station and a plurality of FEC transband remote stations transmit data and corresponding error correction data therebetween during time frames. The time frames are divided into in-band time slots during which the traffic data is transmitted and out-of-band time slots during which the error correction data may be transmitted. The FEC transband remote stations that are assigned to the out-of-band time slots are efficiently and dynamically adjusted during communication.

Abstract: A fuel rail for a fuel injection system is disclosed. The fuel rail includes a first portion including a generally elongated base, at least one mounting bracket and a plurality of fuel cup openings in the generally elongated base. The fuel rail also comprises a second, generally U-shaped, portion having a first and second opposing sides. Each of the first and second opposing sides are sealingly connected to the generally elongated base with a laser weld. The second portion also has a supply end having a fuel supply opening, and a closed end, distal from the supply end. The closed end and the supply end are sealingly connected to the generally elongated base with a laser weld. A method of manufacturing the fuel rail is also disclosed.

Abstract: A noise-maker includes an enclosed membrane having an inlet and an outlet that is filled with porous material. The noise-maker is in an inflated state when the porous material is saturated with air and a compressed state when the air is forced out of the porous material. When pressure is applied to the noise-maker, the air inside the membrane is forced through the outlet and the noise-maker reaches the compressed state. When the pressure is released, the noise-maker changes from the compressed state to the inflated state as air flows through the inlet.

Abstract: An adaptable DC power consumption circuit is provided, wherein a controller alternately operates an RF amplifier during a high RF output power condition, and bypasses the RF amplifier during a low RF output power condition. In this manner, linear operation of the RF amplifier can be maintained while maximizing the power efficiency of the RF amplifier.

Abstract: A cellular telephone system maintains a database of prepaid cellular telephone service accounts, including an amount of money remaining in each account. The system uses modems in a blank-and-burst mode to send data and commands over a voice channel. When a call is attempted over a mobile unit, the system sends identification information stored in the mobile unit to a debit processing unit, which then permits the call and debits the associated account if a sufficient amount of money remains in the account, otherwise it terminates the call.

Abstract: An adaptable DC power consumption circuit is provided, wherein the voltage supplied to an RF amplifier is dynamically varied from a desired level. A feedback control loop is formed between the power terminal and a control terminal of a variable voltage supply. A controller influences the feedback control loop to properly set the supply voltage at the desired minimum level necessary to maintain linear operation of the RF amplifier. The output of the RF amplifier influences the feedback control loop to dynamically vary the supply voltage from the desired level. In this manner, linear operation of the RF amplifier can be maintained while maximizing the power efficiency of the RF amplifier.

Abstract: A radiotelephone system provides a voice channel for carrying voice signals between a mobile unit and a called or calling unit. A first modem in the mobile unit and a second modem connected to a point along the voice channel employ a "blank-and-burst" method of communication to provide a data channel between a first data device connected to the mobile unit and a second data device connected to the second modem. The data channel enables the data devices to communicate with each other seemingly concurrently, and with minimal interference, with the voice signals that are being carried over the voice channel and without requiring modifications to any base station.
