    • A method is disclosed for assembling a multi-stage compressor or a multi-stage turbine for use in a gas-turbine engine. The method comprises the steps of assembling a rotor drum so as to comprise a plurality of rotor discs 17, 18, and then releasably connecting a plurality of static components 38 to the assembled rotor drum 19, thus forming an intermediate structure. The intermediate structure is then inserted within an outer casing 50, preferably by lowering the outer casing 50 over the intermediate structure, whereafter the static components 38 are fixed to the outer casing 50. The static components 38 are then released from their connection to the rotor drum 19 in order to permit rotation of the drum 19 relative to the static components 38 and the outer casing 50.

    • An inductively coupled power transfer receiver including a tunable circuit and a power supply circuit. The tunable circuit includes a power receiving coil in series with a first capacitance and a first variable impedance connected in parallel with the power receiving coil. The variable impedance includes at least one impedance element and one or more semiconductor devices for controlling the effective impedance of the first variable impedance. The first variable impedance may be a second capacitance in series with the first semiconductor device; an inductance in parallel with the first semiconductor device; a second capacitance in parallel with the first semiconductor device; or a capacitance and an inductor in parallel with the first semiconductor device. The power supply circuit includes a power control circuit which provides a control signal to the first variable impedance based on an output voltage produced by the power supply circuit.

    • A wireless mobile unit includes a voice encoder circuit that receives an analog voice signal and creates digital voice data representing a user's voice. The mobile unit receives an encryption key entered by the user, typically on the keypad or through a voice recognition circuit, and stores the encryption key in a storage device. An encryption circuit encrypts the digital voice data using the encryption key. A transmitter then modulates the encrypted voice data onto an RF signal and transmits the RF signal to a base station in a wireless network. The base station uses the same encryption key to decrypt the signal before transmitting it to another base station or mobile unit. Signals transmitted from the base station to the mobile unit are encrypted and decrypted using a user-selected encryption key in a similar manner.
    • 无线移动单元包括接收模拟语音信号并创建表示用户语音的数字语音数据的语音编码器电路。 移动单元接收用户输入的加密密钥,通常在键盘上或通过语音识别电路,并将加密密钥存储在存储设备中。 加密电路使用加密密钥加密数字语音数据。 然后,发射机将加密的语音数据调制到RF信号上,并将RF信号发送到无线网络中的基站。 基站使用相同的加密密钥在将信号发送到另一个基站或移动单元之前解密该信号。 从基站向移动单元发送的信号以类似的方式使用用户选择的加密密钥进行加密和解密。
