Patent number: 8700351Abstract: Measurement apparatus is described that comprises a measurement portion for acquiring object measurements and an output portion for outputting measurement data relating to the acquired object measurements. A deactivation portion is provided for inhibiting normal operation of the measurement apparatus such that output of the measurement data is prevented. The deactivation portion, in use, reads apparatus usage information from an apparatus usage module and inhibits normal operation of the measurement apparatus if said apparatus usage information fails to meet one or more predetermined criteria. The apparatus usage module may be provided as an integral part of the measurement apparatus or as a separate activation button. The measurement apparatus may comprise a measurement probe such as a touch trigger measurement probe.Type: GrantFiled: February 14, 2013Date of Patent: April 15, 2014Assignee: Renishaw PLCInventors: Tim Prestidge, Jonathan Paul Fuge, Stuart Kersten Campbell

Patent number: 8140287Abstract: A probe for measuring the dimensions of objects on a coordinate positioning machine such as a machine tool has a workpiece-contacting stylus. This is suspended via a sensor mechanism, including strain gauges which provide an output when the stylus contacts a workpiece. A processor processes the strain gauge outputs to produce a trigger signal. It does so in accordance with an algorithm or equation or look-up table which ensures equal sensitivity in all possible directions of approach to the workpiece in the three dimensions X, Y, Z.Type: GrantFiled: July 21, 2010Date of Patent: March 20, 2012Assignee: Renishaw PlcInventors: Tim Prestidge, Jonathan Paul Fuge

Patent number: 7812736Abstract: A probe has internal circuitry capable of operating in a plurality of different modes, for example a variety of filter modes and turn off modes. A switch on the probe sends an input to a controller which is arranged to set the mode in response to operation of the switch. The switch may be a push button which is operated externally of the probe by means of an actuator in the form of a plunger. The probe has a workpiece-contacting stylus mounted on a seat from which it is deflectable. The stylus and the seat may comprise the switch. An indicator, e.g., an LED, indicates the mode in response to an output from the controller. The controller outputs a plurality of indications of different modes in a sequence and a mode is selected by operating the switch once the desired mode is indicated.Type: GrantFiled: January 6, 2009Date of Patent: October 12, 2010Assignee: Renishaw PLCInventors: David Collingwood, Jonathan Paul Fuge, Geoffrey Salt

Patent number: 7689379Abstract: A dimensional measurement probe (10) is mounted in a machine tool (48), which reorientates the probe about at least one axis A. Strain gauges (34) sense when a stylus (20) of the probe contacts a workpiece (50), to produce a trigger signal. False trigger signals may be produced when the probe is reorientated. To overcome this, the reorientation is detected by monitoring changes in the fluctuations of the strain gauge outputs, caused by vibrations of the stylus.Type: GrantFiled: June 15, 2006Date of Patent: March 30, 2010Assignee: Renishaw PLCInventors: Jonathan Paul Fuge, Michael John Wooldridge, Jamie John Buckingham, Peter Kenneth Hellier

Patent number: 7316077Abstract: A probe (10) for a machine tool has a switch (32) or other sensor for connecting its battery power supply in response to movement of the probe. In a preferred embodiment, the switch responds to rotation of the probe in the machine tool spindle. The switch (32) is responsive to linear accelerations, but is mounted in the probe so as to respond also to the rotation. A circuit is provid to discriminate between the rotation and linear movements.Type: GrantFiled: March 13, 2004Date of Patent: January 8, 2008Assignee: Renishaw, PLCInventors: Jonathan Paul Fuge, Robin William Cashmore, David Collingwood, Mark Acres

Patent number: 7315018Abstract: The invention relates to a device and method for analysis of a tool (50) e.g. used on a machine tool. A tool detector (5) includes a light emitter (12) and a light receiver (34). Tool (50) when progressed into a beam (20) of light emitted from the emitter (12) will cause a signal from the receiver to change. Circuitry (32) includes a digital signal processor which processes the signal from the receiver and produces an output only if the signal conforms to a predetermined condition. Preferably this predetermined condition could be e.g. a characteristic shape of the signal from the receiver, a change in a value derived from a succession of such signals or a change in the minimum or maximum values of a succession of signals from the receiver.Type: GrantFiled: December 18, 2003Date of Patent: January 1, 2008Assignee: Renishaw PLCInventors: Sharon Ann Ashton, Victor Gordon Stimpson, Jonathan Paul Fuge, David Roberts McMurtry

Patent number: 7145468Abstract: A probe 10 has internal circuitry capable of operating in a plurality of different modes, for example a variety of filter modes and turn off modes. A switch on the probe sends an input to a controller which is arranged to preset the mode in response to operation of the switch. The switch may be a push button 32 which is operated externally of the probe 10 by means of an actuator in the form of a plunger 34. The probe has a workpiece-contacting stylus 11 mounted on a seat from which it is deflectable. The stylus and the seat may comprise the switch. An indicator, eg an LED 44, indicates the mode in response to an output from the controller. The controller outputs a plurality of indications of different modes in a sequence and a mode is selected by operating the switch once the desired mode is indicated.Type: GrantFiled: February 1, 2002Date of Patent: December 5, 2006Assignee: Renishaw PLCInventors: David Collingwood, Jonathan Paul Fuge, Geoffrey Salt

Patent number: 6941671Abstract: A touch-trigger probe is described having a workpiece-contact sensor (15) in the form of a kinematic seating (10) and workpiece contacting stylus (12). A processor ?P in the form of a reprogammable PIC microcontroller is used to monitor the signal from the sensor (15). When the signal is above a threshold for a continual period of time (CT) then the processor issues a trigger signal. The monitoring of the time period (Ct) may be delayed. This delay (Ci) allows triggering initiated by the shock wave produced initially when workpiece contact occurs.Type: GrantFiled: September 5, 2002Date of Patent: September 13, 2005Assignee: Renishaw PLCInventor: Jonathan Paul Fuge

Patent number: 6860026Abstract: A probe for position determining apparatus such as a machine tool transmits optical measurement signals to a receiver module. The probe is battery powered and the battery powers light emitting diodes which transmit the optical measurement signals. The optical measurement signals comprise serially transmitted codewords which are generated by a universal synchronous/asynchronous receiver transmitter (USART). The output of the USART is combined with a pulse width modulator which has an output having the same form as the output of the USART but with reduced duration of each pulse, thus enhancing the life of the battery powering the light emitting diodes. The pulse width modulator may also be used to set the timing of the USART.Type: GrantFiled: June 14, 2002Date of Patent: March 1, 2005Assignee: Renishaw PLCInventor: Jonathan Paul Fuge
