摘要： The present invention provides a precision alignment system operable to provide alignment of a first and second apparatus. The precision alignment system makes use of inductive coupling between loop antennas in the first and second apparatus. The mechanism for alignment is the detection of a null in the signal induced in the loop antennas of the second apparatus arising from an input signal fed to a loop antenna of the first apparatus. The precision alignment system can be incorporated in a system for the wireless transfer of electrical power or may be incorporated in a system for the transfer of data. The precision alignment system of the present invention is particularly suited to applications where optical or other means for alignment of two apparatus are unreliable. In particular, the alignment system disclosed is suitable for operation underwater.

摘要： The present invention provides an underwater navigation system which can determine the bearing and the range of a remotely located beacon from a navigation station. The remotely located beacon transmits a pair of signals each having a different propagation velocity. Typically, the pair of signals are an acoustic signal and an electromagnetic signal. The range of the beacon to the navigation station is determined by a time differential in the detection of the two signals at the navigation station. The time differential is alternately a variation in phase between the two signals, or a time difference between the reception of a timing event encoded in synchronization on the pair of signals. In one form, the navigation station is a mobile unit which navigates to the remotely located beacon, and in another form the navigation station has a fixed position, and the remotely located beacon is mobile.

摘要： A two-tier wideband antenna comprising a chip of a dielectric material with an upper radiating structure and a lower radiating structure, the dielectric chip being mounted on an insulating carrier substrate which includes a feed-line to connect the antenna to a transceiver device. The lower radiating structure comprises two side elements which have a large aspect ratio so as to reduce the frequency of the lower band edge of the frequency response of the antenna when compared with the frequency response of a monopole patch antenna fabricated on a similar dielectric chip. The antenna of the present invention is suitable for operation over an ultra wideband, e.g. a frequency range extending from 3.1 to 10.6 GHz.

摘要： A method is disclosed for providing an indication that a vehicle has exceeded a safe driving speed. The speed and position of an obstacle are combined with a driver reaction time to arrive at a safe maximum speed. The driver reaction time is predicted based not only on generic values as in known systems, but also on at least one scaling factor which can be, for example, a scaling factor which penalises increased driving duration, or driver age, or experience, or weather conditions.

摘要： A miniaturised half-wave balun comprises a single-ended I/O port comprising a first signal carrying terminal for connection to a source impedance and a differential I/O port comprising second and third signal carrying terminals for connection to a load impedance. First and second transmission line sections of equal length and characteristic impedance are connected together at a common end and at opposite ends to the second and third terminals. The first signal carrying terminal is coupled to the first transmission line section. The combined length of the first and second transmission line sections is substantially less than one half of the wavelength of an RF signal at the operating frequency. First and second loading shunt capacitors are connected to respective first and second transmission line sections. A shunt capacitive element is connected at the common end of the transmission line sections. The capacitance of the shunt capacitive element is chosen so that the common mode impedance of said differential I/O port at a selected frequency is substantially zero Ohms.

摘要： A compact RF differential circuit has a first differential I/O port comprising a first pair of signal carrying terminals which is connected to a source termination and a second differential I/O port comprising a second pair of signal carrying terminals which is connected to a load termination. The common mode impedance measured at either the first or second differential I/O port is zero. The differential mode impedance measured at the first differential I/O port is equal to the differential mode impedance of the source termination, and the differential mode impedance measured at the second differential I/O port of the circuit is equal to the differential mode impedance of the load termination. The circuit attenuates the common mode component of an RF signal which is incident on the first I/O port of the circuit so that a signal emitted from the second I/O port of the circuit has a differential mode component which is substantially greater than the common mode component and the circuit attenuates the common mode component of an RF signal which is incident on the second I/O port of the circuit so that a signal emitted from the first I/O port of the circuit has a differential mode component which is substantially greater than the common mode component.

摘要： A substrate for mounting a device is disclosed. The substrate includes at least one transition for providing an RF connection to a lead of the device, the lead extending from a device input to an otherwise free end. The transition comprises two spaced apart electrically coupled members, the first member occupying at least the same area on a top surface of the substrate as the device lead to which it is to connect, and the second member lying in register with the first member. The transition comprises an input, which is located at the end of the second member which is nearest the free end of the device lead and an output which is located at the opposite end of the first member and which is in register with the device input. The electrical characteristics of the transition are such that the electrical length from the input of the transition to the output of the transition is approximately equal to one half of a wavelength over a given operating frequency band of the device.
