摘要： Apparatus for digitising an impedance is described that comprises a first impedance element (22; 122) having a first impedance (C1;A1) that varies with a property to be measured and a second impedance element (24; 124) having a second impedance (C2;A2). The apparatus also includes a drive signal generator (26,30) for applying a first alternating drive signal (44) to the first impedance element (22; 122) and a second alternating drive signal (46) to the second impedance element (24; 124). An analogue-to-digital converter, ADC (42; 142), receives a resultant signal (41;52; 141 ) comprising the combination of the signals produced by the application of the first and second alternating drive signals (44,46) to the first and second impedance elements (22,24; 122, 124). The first alternating drive signal (44) is phase shifted relative to the second alternating drive signal (46) such that the resultant signal (41;52;141) received and sampled by the ADC (42; 142) sequentially relates to the sum of, and the difference between, the first and second impedances. The apparatus also comprises a signal separator (56;156A,156B) that receives sample values from the ADC (42; 142) and generates a sum channel (58; 158A) and a difference channel (60; 160A) therefrom.

摘要： An inductive transmission system for a probe for use on a coordinate positioning machine such as a machine tool. The probe (10) is connected via a probe interface (14) to a single coil (16). This is inductively coupled across a small gap to a second coil (30), which is connected via an interface circuit (12) to the machine control. Data signals pass from the probe (10) to the interface (12). Simultaneously, a power carrier signal and a command signal pass from the interface (12) to the probe (10). In order that all these signals can pass without mutual interference via the coils (16, 30), each signal has a carrier of a different frequency, and the signals are carried in frequency bands which do not overlap.

摘要： A displacement responsive device e.g. a measurement probe (110) is disclosed. Displacement of a stylus (130) causes resilient movement of a carriage (134) supported by planar springs (112) and (114). This movement is detected by a capacitance sensor (160), formed from two cylinders (164) and (166). The cylinders move in at least three degrees of freedom and changes in their capacitance during the said movement can be determined by a circuit (e.g. Fig 5). Movement in x, y and z directions can be sensed.

摘要： A probe (10) is adapted to track a surface (12A) of a workpiece (12) with a view to determining the profile thereof. The probe (10) is adapted to adopt a position, with respect to the surface (12A), in which a sensing axis (A1) of the probe (10) is normal to the surface (12A). To this end, the probe (10) has a sensor system (L1) for detecting the slope (S) of the surface (12C) relative to a reference plane (RP) transverse to the sensing axis (A1), and a control system is provided for positioning the probe (10) angularly so as to tend to reduce any slope error (Sx) between the surface (12A) and the reference plane (RP) to zero.

摘要： A signal conditioning circuit for multiple channel capacitive displacement transducers. The transducer (30) comprises three differential capacitive transducers, driven by respective square waves from modulators (32x, 32y, 32z). The modulators are driven at different frequencies which are even multiples of each other, derived from a divider (68). The signals from each differential capacitance pair of the transducer (30) are received by a common charge amplifier (48). They are then demodulated by respective phase sensitive rectifiers (50x, 50y, 50z), each of which is driven at the same frequency as the corresponding modulator. The outputs of the phase sensitive rectifiers are integrated, e.g. by circuits (60, 62, 44) for one of the channels, and the resulting voltage signal is fed back to the corresponding modulator so as to tend to null the input to the charge amplifier (48). The use of modulating frequencies which are even multiples of each other enables the signals to be multiplexed through a single charge amplifier (48). The mechanical construction of the multi-channel transducer (30) is also described.

摘要： A workpiece inspection system is disclosed for determining measurements of a workpiece on a machine tool. The system utilises a measurement device which outputs data relating to the workpiece ( e.g. in place of a conventional cutter). The problem of obtaining real time data relating to the position of the machine tool is overcome by recording a machine tool position data set and a measurement device data set at selected instants which are defined by a synchronisation signal. The data sets are combined later in the correct relative position because the synchronisation signal was used. The synchronisation signal can issue from the machine tool controller, an interface, measurement device or another part of the system.
