Downhole apparatus
First Claim
1. A downhole apparatus configured to move through a well in rock for operation in a in a drilled bore, the downhole apparatus being configured to be installed temporarily or permanently in the drilled bore, the apparatus comprising:
- a first part; and
a second part connected to the first part,wherein the second part comprises a first electronic device configured to generate a data signal and a first communications device for wirelessly transmitting the generated data signal via a wireless short-range radio-frequency communications channel,wherein the first part comprises a second communications device for wirelessly receiving the transmitted data signal via said wireless short-range radio-frequency communications channel,wherein the first and second communications devices in use are configured to communicate with each other via the short-range radio-frequency communications channel,wherein the wireless communications channel operates in a 2.4 GHz radio communication spectrum,wherein the first part comprises a reservoir comprising a fluid and sealed from a pressure chamber comprising a fluid and a piston dividing the pressure chamber into a first and a second piston pressure chamber fluidly coupled via a pump;
wherein the second part is attached to the first part via a hollow tubular member extending from the reservoir through the pressure chamber; and
wherein the hollow tubular member is attached to the piston such that translation of the piston via a pressure difference between the first and a second piston pressure chamber established by the pump results in translation of the hollow tubular member and the second part.
