Abstract: A system including first and second network nodes that communicate with additional nodes in first and second networks, respectively, using a shared communication channel. In response to detecting presence of the first network node, the second network node transmits a first signal to the first network node including a predetermined sequence known to both the first and second network nodes. The first network node measures a strength of the transmitted signal based on knowledge of the predetermined sequence and calculates a throughput metric (throughput referring to amount of information transmitted per second) based on the measured strength. In response to the throughput metric being less than a unification threshold, the first network node selectively transmits a unification request to the second network node. The unification request invites the second network node to coordinate operation with the first network node to reduce interference between the first network and the second network.

Abstract: A perforating gun designed to orient a charge holding structure (e.g., tube, solid rod) within a barrel of the perforating gun to be at the same position relative to a wellbore casing regardless of a position of the barrel of the perforating gun. A charge assembly receivable within the barrel includes the charge holding structure and first and second end caps that are rotatably interconnected to the charge holding structure and non-rotatably interconnected to the barrel. As the charge holding structure is always or substantially always designed to maintain a common orientation in relation to the wellbore casing, explosive charges associated with the charge holding structure so as to fire towards particular location on the wellbore casing may always or substantially always perforate such particular locations upon or after the explosive charges have fired.

Abstract: A method for simultaneous transmission in time and frequency of multiple communications of data using orthogonal frequency division multiplexing (OFDM) modulation includes transmitting the multiple communications of data at a same time on a single channel. A first starting signal, transmitted using a first network device, and a second starting signal, transmitted using a second network device, are used in transmission of a frame. Properties of the first starting signal and the second starting signal for transmission of each of the multiple communications are modified by shifting a frequency of the first starting signal with respect to a frequency of the second starting signal so that remaining communications coincident in time and frequency with respect to a given communication are ignored. The frequency of the first starting signal is shifted an amount equal to a fraction of a separation between carriers of the OFDM modulation.

Abstract: The object of this invention relates to a procedure for treatment, both preventive and corrective, of dental cavities. Said procedure consists fundamentally in irradiation of the dental surface to be treated with a Neodymium YAG laser in conformity with specific parameters and conditions, signifying an advance in respect of the state of the art in this field. In the case of the treatment of cavities for corrective purposes it is also necessary, among other stages, to apply a dental cementing and restorative biomaterial on the surface of the dental enamel or on the dentin in such a manner that irradiation by the laser produces microfusion between both thereof. The present invention also relates to the biomaterial used in the procedure described herein, preferentially based on hydroxyapatite, together with the use of the procedure and of the biomaterial in the treatment of dental cavities.
