Title: Method for closing perforated membranes
Inventor: PANNEK THORSTEN
IPC: B81C1/00
Filed: 2004-12-10
Abstract: A membrane structure includes a membrane layer which can be a carrier for micromechanical functional elements such as thermal sensors. A fine-pored layer 2 having pore sizes of a few nanometres is produced on a substrate 1 in the region where the membrane 3 is to be formed, using a porous silicon technology. The porous silicon is oxidised to protect it during an etching process. CIF3 gas is used as an etchant, which penetrates through apertures formed photolithographically in the membrane and pores of the fine-pored layer, underetching the membrane and forming a cavern 6 in the substrate.

Title: Transmitter power controlled by measurement of output spectrum
Inventor: BRICE CHRISTOPHER E
IPC: H03F1/02
Filed: 2004-12-17
Abstract: A transmitter 100, in particular for a GSM cellular communication system, includes a power amplifier 103 and a coupling element 107. The coupling element 107 couples a portion of the output signal of the amplifier 103 to a measurement controller 109. The controller 109 determines a non-linearity indication of the power amplifier 103 from the output signal. The measurement controller 109 may measure the signal level in an out-of-band frequency interval, where spurious signals can arise if operation of the power amplifier 103 moves into a non-linear region. This may be caused by falling battery voltage. The measurement controller 109 is connected to a power controller 111 which controls the output power of the power amplifier in response to the non-linearity indication. The power controller 111 may gradually reduce the output power in response to the non-linearity indication, or de-activate the power amplifier 103 if the indication exceeds a given threshold. The invention may in particular allow for a delayed switch-off of the power amplifier 103 during battery back-up operation.

Title: Changing the transfer characteristic of an electrical circuit
Inventor: BENNETT STEVE
IPC: H03F1/30
Filed: 2005-04-06
Abstract: A non-linear transfer characteristic of an electrical circuit is achieved by changing the behaviour of the feedback loop of the electrical circuit at a predetermined level of input signal. The output of the circuit has a proportional relationship with the input until the input signal reaches this predetermined value, whereupon the behaviour of the feedback loop changes. While the input signal is above the predetermined value, the output of the circuit has a linear but disproportionate relationship with the input at a gradient different to that when the input signal is below the predetermined value. Further, the behaviour of the feedback loop changes to create a knee point in the response between the proportional and the linear parts of the characteristic. The sensitivity to input signals may be greatest below the knee point and the circuit may be used as a detection system in which a single sensor is employed to detect an extensive range of a parameter.

IPC: G01S13/78
Filed: 2006-10-12
Abstract: This invention relates to a method for determining the reply efficiency of a DME navigation beacon and to an apparatus for performing the method. The invention involves locating an RF receiver 6 nearby a DME beacon 4 to be tested. The RF receiver 6 analyses all signals received on the interrogation frequency of that beacon 4 to determine pulse pairs which correspond to a valid interrogation of that beacon. The RF receiver 6 also records all signals on the reply frequency of the beacon 4 and detects all replies sent by the beacon. Particular interrogations can then be correlated with replies and the reply efficiency of the beacon determined. Several RF receivers (30a-30e,Fig5) may be located round the beacon 4 to better provide correlation between particular interrogations and responses. In a further embodiment the RF receivers may be further used for aircraft location whereby the time difference of arrival of the relevant interrogation pulse pair at each RF receiver (30a-30e,Fig5) relative to the DME transponder 4 is determined and multilateration is performed using each time difference of arrival to determine the relative location of the source of the relevant interrogation pulse.

Title: A method of controlling a powershift transmission during change-of-mind shifts
Inventor: JIANG HONG
IPC: F16H3/00
Filed: 2006-12-01
Abstract: A method of controlling a powershift transmission during change-of-mind shifts comprises shifting the transmission from a current gear to a target gear and determining in step 104 if an accelerator pedal has been released, if yes then in step 106 two clutches (22, 24, fig 1) are stroked/disengaged so as to transmit zero torque. In step 108 the target gear is determined and this is used in step 110 to determine a preselected gear which is coupled to an output shaft (32) by one of a plurality of couplers (42, 44, 46, 48) and one of the clutches (22, 24). If it is established in step 114 that the accelerator pedal is closed and it is also determined in step 115 that the coupler (42, 44, 46, 48) has not connected the preselected gear to the output shaft (32) then in step 118 the transmission is shifted from the current gear to the target gear using the clutch and coupler. If in step 116 the preselected gear is connected to the output shaft (32) then in step120 the transmission is shifted from an appropriate gear to the target gear.
