Advanced inground device power control and associated methods
First Claim
1. A transmitter that is powered by a battery and is receivable in each one of a plurality of different housings each of which housings is characterized by a different housing design and each of which forms part of an inground tool for performing an inground operation in which a drill string extends from a drill rig to the inground tool, said transmitter comprising:
- a regulator for generating a regulated voltage from said battery;
an antenna driver powered from the regulated voltage for electrically driving an antenna to emanate an electromagnetic signal for remote reception based on power consumption from the regulator; and
a controller that monitors the power consumption and selectively limits the power consumption based on at least one power consumption threshold while continuing to drive the antenna to emanate the electromagnetic signal, when the transmitter is installed in one of the plurality of housings where the transmitter would otherwise exhibit a different power consumption that exceeds the power consumption threshold when so installed based on each housing design exhibiting a different housing-attributable signal attenuation of the electromagnetic signal.

Abstract
A transmitter is powered by a regulated battery voltage and is installable in one of a plurality of different housings, each housing is characterized by a different design and each can form part of an inground tool for performing an inground operation in which a drill string extends from a drill rig to the inground tool. An antenna driver drives an antenna based on the regulated voltage to emanate an electromagnetic signal for remote reception. A controller limits power consumption from the regulated voltage so as not to exceed a power consumption threshold, irrespective of installation of the transmitter in any one of the housings when the transmitter would otherwise exhibit a different power consumption for each housing design. A corresponding method is described. Features relating to power consumption threshold modification based on temperature as well as mechanical shock and vibration are described.

19. A method for operating a transmitter that is powered by a battery and configured for installation in one of a plurality of different housings, each of which housings is characterized by a different housing design and each of which can form part of an inground tool for performing an inground operation in which a drill string extends from a drill rig to the inground tool, said method comprising:
-
generating a regulated voltage from said battery; electrically driving an antenna using power consumption from the regulated voltage to emanate an electromagnetic signal from the transmitter for remote reception; and monitoring the power consumption and, responsive thereto, limiting power consumption of the transmitter from the regulated voltage while continuing to drive the antenna to emanate the electromagnetic signal based on a power consumption threshold, when the transmitter is installed in any one of the plurality of housings when the transmitter would otherwise exhibit a different power consumption that exceeds the power consumption threshold when so installed based on each housing design exhibiting a different housing-attributable signal attenuation of the electromagnetic signal.
