Filed:

Mar 14, 2013

Appl. No.:

13/829731

Inventors:

Benjamin John Medeiros - Orting WA, US
Jason Pothier - Auburn WA, US
Dmitry Feldman - Seattle WA, US

Assignee:

Merlin Technology Inc. - Kent WA

International Classification:

G01P 15/08
G01P 21/00

US Classification:

73 138, 73497

Abstract:

A device is described for use in performing an inground operation. An accelerometer is supported by the device for generating accelerometer readings that characterize the inground operation subject to a native temperature drift of the accelerometer. A set of compensation data is developed and stored for use in compensating for the native temperature drift. The compensation data is applied to the accelerometer readings to produce compensated accelerometer readings that externally compensate for the native temperature drift to yield an enhanced thermal performance which is improved as compared to a native thermal performance of the accelerometer. A seven position calibration method for a triaxial accelerometer is described. An air module is described which isolates the accelerometer of the device at least from a potting compound that at least fills otherwise unoccupied volumes of the device interior.

Appl. No.:

16/841641

Inventors:

- Kent WA, US
Jason Pothier - Auburn WA, US

International Classification:

E21B 47/12
E21B 7/04

Abstract:

An inground housing supports a transmitter for receiving electrical power from a battery. The transmitter transmits at least one signal using at least two different transmit power levels for at least one of locating the transmitter and characterizing an orientation of the transmitter. Based on detecting the battery voltage, the transmitter selects one of the transmit power levels. Transmitter output power can be controlled based on one or both of signal gain and duty cycle.
