Embodiment Construction

[0033] refer to figure 1 , figure 1 A temperature measuring probe system according to the invention is shown. The system includes an interface 2 , a temperature probe 4 that can be installed on the spindle and a fixed temperature probe assembly 6 .

[0034] The interface 2 is configured to communicate with the spindle mountable temperature probe 4 and the fixed temperature probe assembly 6 via a Bluetooth (registered trademark) communication link 8 whenever temperature data is required. The Bluetooth communication standard is a frequency hopping spread spectrum wireless link known to those skilled in the art, referred to herein as Bluetooth. Accordingly, the interface 2, the spindle mountable temperature probe 4 and the fixed temperature probe assembly 6 each contain a Bluetooth communication module or component, which will be described in more detail below. The interface 2 also includes a hardwired communication link 9 for communicating with an associated machine tool cont...

Abstract

A wireless device (4,6) is described that comprises a spread spectrum radio-frequency (RF) communications portion, such as a Bluetooth module, and an ancillary RF receiver portion (24). The spread spectrum RF communications portion is activated on receipt of a characteristic RF signal by the ancillary RF receiver portion (24). The ancillary RF receiver portion (24) may consume substantially less power than the spread spectrum RF communications portion thereby allowing a low power standby mode to be implemented. The wireless device may be a measurement probe (4), such as a temperature probe, for use with machine tools and the like. An interface (2;50) for transmitting the characteristic RF signal is also described.

Description

technical field [0001] The present invention relates to a wireless communication device and in particular to a measuring probe for use with a machine tool comprising said wireless communication device. Background technique [0002] Many types of wireless devices are known to transmit and receive data over radio frequency (RF) communication links. For example, WI-FI (registered trademark) or frequency hopping spread spectrum communication systems such as Bluetooth (registered trademark) are widely used to establish wireless computer networks. It has also been described before how a Bluetooth communication module can be activated by an associated low power receiver in the form of a radio frequency identification (RFID) tag. For example, US2007 / 0015465 describes an electronic RFID tag that can be used to activate a Bluetooth module. Arrangements of a similar type have also been proposed previously in US2003 / 107475 and WO03 / 065289. [0003] It is also known in the metrology f...
