Title: Calculating the amplitude of a signal from I and Q components for use in a transmitter gain control or predistorter
Inventor: ICHIHARA MASAKI
IPC: H04L27/20
Filed: 2000-07-06
Abstract: An amplitude calculation circuit permits accurate calculation of an amplitude with quite small circuit scale and power consumption. The amplitude calculation circuit converts input I (in-phase component) Q (quadrature-phase component) base band signals in first and second absolute value circuits 111,112 into an input vector V<SB>in,0</SB> (Fig 6). A first phase rotation circuit (R<SB>0</SB>) 101 rotates the input vector V<SB>in,0</SB> in the clockwise direction for an angle   R  <SB>0</SB> = 45{ and multiplies the amplitude by 1/cos (  R  <SB>0</SB>) to output an output vector V<SB>out,0</SB>. By deriving the absolute value of the output vector V<SB>out,0</SB> by a third absolute value circuit 113, a vector V<SB>in,1</SB> symmetric to the X-axis is established. Subsequently, the foregoing operation is repeated by the second to fifth phase rotation circuits 102-105 and fourth to sixth absolute value circuits 114-116.

Title: A bipolar differential amplifier with a tail resistor
Inventor: NEWTON ANTHONY
IPC: H03F3/45
Filed: 2001-07-27
Abstract: A bipolar differential amplifier having first and second transistors (Q1, Q2) and a large third transistor (Q3) sharing a common load resistor (Rt), and DC biasing for biasing the bases of the first, second and third transistors, whereby the first and second transistors have a DC operating current whose value <I><B>I</B></I> is related to the common resistor value <I><B>Rt</B></I> and the thermal voltage <I><B>Vt</B></I> by the expression <F><I><B>Rt = Vt/2I</B></I></F>. In this way the gain of the differential amplifier remains substantially constant over a wide range of the input signal. This produces advantages of: a wide range of linear operation, a relative low bias current may be used, and lack of noise at the central operating point introduced by the large third transistor and the load resistor.

Title: Flight surface actuator
Inventor: DAVIES JONATHAN PAUL
IPC: B64C13/32
Filed: 2003-03-05
Abstract: An aircraft flight surface actuator comprises a bracket 10, in which is mounted a cam mechanism 20, mounted on a bearing 12. The cam 20 is attached to a lever mechanism comprising a link 14 and a lever arm 3, which in turn is attached to the flight control surface. In use, the actuator may be driven by a torque tube connected to a gearbox, drive being transmitted to the gearbox via an additional tube mounted within the first. The drive rotates the cam, causing the lever 3 to pivot on the bracket, thus moving the flight control surface. In use, the cam can rotate about 180{, and at each extremity, the pivot point of both the cam 20, and the connection between the link 14 and lever 3 are situated on the plane of symmetry of the cam 20, meaning the load on the flight control surface (e.g. flaps) will not apply torque to the mechanism, and therefore not be able to back drive the actuator.
