Abstract: Front end circuits and associated apparatus, systems, and methods for use in electronic devices such as buried utility locators are disclosed. The circuits include receivers and filters on input signals that are coupled to ground rather than differentially. A multiplexing circuit allows shared use of amplifiers, and analog-to-digital converters via a switching mechanism for selectively making or breaking electrical connection to the receiver channels for efficient sharing of electronics resources while minimizing crosstalk interference and advantageously reducing costs.

Abstract: Disclosed is a combo antenna module in which an accommodation groove is formed in a coil pattern and a connection pattern connected to a coil pattern disposed on another surface is disposed in the accommodation groove so as to minimize a mounting space and provide antenna performance greater than or equal to that of a conventional antenna module. The disclosed combo antenna module comprises a coil pattern for short-range communication and a coil pattern for wireless power transmission. The coil pattern for wireless power transmission has the accommodation groove formed by varying the line width of the coil pattern disposed on one surface, and the connection pattern for connecting the coil patterns disposed on the other surface is disposed in the accommodation groove so as to minimize a mounting space and provide antenna performance greater than or equal to that of a conventional antenna module.

Abstract: The system performs communication between two systems, a master system, that creates an alternating magnetic field by means of which it dialogues with one or more slave systems, which respond at frequencies other than those generated by the master by a non-linear magnetic core generating harmonics of higher order than those of the magnetic field created by the master. The generation of harmonics is controlled by the slave by a short-circuit coil which enables the data transmission from the slave to the master. The slave system can have its own power supply or it can be powered by the short-circuit coil. This allows microcontrollers in the slaves to be powered and give them intelligence and a large storage capacity, making them ideal for control security and monitoring processes. The excitation frequency can be varied because the functionality of the slaves does not depend on the frequency of the exciter field.
