| 20090025243 | Modular Measurement probe - A measurement probe, such as a touch trigger probe, is described that comprises a stylus module attachable to a base module. The stylus module comprising a housing and a stylus holder moveably attached to the housing. The base module comprises a measurement portion for generating measurement data indicative of movement of the stylus holder relative to the housing. The stylus module has an inbuilt failure mode and thereby a substantially predetermined operational lifetime. In one embodiment, the inbuilt failure mode is provided by integrating a battery into the stylus module. Providing a mechanical failure mode in which a component of the stylus module catastrophically fails after a certain amount of usage is also described. | 01-29-2009 |
| 20090028286 | Measurement apparatus and a method of using measurement apparatus - A method of measurement using a measurement probe system includes the steps of (i) providing a measurement probe system having a measurement probe to a user, the measurement probe system being suitable for use with co-ordinate positioning apparatus and (ii) monitoring usage of the measurement probe system. | 01-29-2009 |
| 20090034677 | Deactivatable measurement apparatus - 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. | 02-05-2009 |
| 20090070585 | Measurement probe systems for co-ordinate positioning apparatus - A measurement probe, such as a touch trigger measurement probe, is described that comprises a measurement portion for measuring an object and a data transfer portion for receiving data from and/or transmitting data to an associated unit. The measurement device also comprises an authentication module for verifying the authenticity of the associated unit. The authentication module may include a processor for running a one-way hash algorithm. Authenticity may be established using a challenge and response authentication process. | 03-12-2009 |
