Abstract: A computer system for grid-forming control detects a change of a first magnitude in power delivered at a point of interconnection with an alternating current electric grid. The computer system then generates a non-linear change in frequency at the point of interconnection with the alternating current electric grid. Generating the non-linear change in frequency causes a grid interfacing device to compensate in a non-linear manner for a power imbalance on the alternating current electric grid.

Abstract: In one example, an apparatus comprises an integrated circuit, a first metal layer, and a second metal layer. The first metal layer includes a first antenna connected to the integrated circuit, the first antenna being in a first region, the first region being external to the integrated circuit. The second metal layer includes a second antenna in a second region external to the integrated circuit. The apparatus further comprises a substrate between the first and second metal layers, in which the substrate and the first and second metal layers form a laminate. The apparatus further comprises a through-via in the substrate that couples between the first and second antennas.

Abstract: An electronic device includes a printed circuit board (PCB) with electronics configured to generate and receive data by a radio-frequency carrier signal via a signal terminal. A monopole antenna having first and second ends is connected to a signal terminal of the PCB at the first end. A first section of the antenna extends away from the signal terminal by a first length in a first direction. A second section of the antenna extends away from the first section by a second greater length in a second direction different from the first direction. The first section is spaced apart from the PCB by a third section of the antenna, and the second end of the antenna is spaced apart from the PCB by a dielectric spacer. The length of the antenna may be ¼ of a carrier frequency provided by the signal terminal.

Abstract: Trigger devices for igniting an exothermic reaction is provided. The trigger devices may be flint type trigger devices and electronic type trigger devices. The flint type trigger device has a housing with a spark opening on a rear wall of the housing. A mold mounting assembly is secured to an exterior of the rear wall of the housing. A motor assembly is secured to the inside of the rear wall of the housing. The motor assembly has a flint wheel attached to a shaft of a motor, where the flint wheel is located adjacent the spark opening. A flint assembly is positioned within the housing such that a flint of the flint assembly is in contact with the flint wheel. A controller positioned within the housing is configured to selectively activate the motor to cause the flint wheel to rotate against the flint to create one or more sparks that are ejected from the spark opening.

Abstract: The present disclosure provides protective coverings formed by releasably attaching a mold to a metal structure over a connection, such as an exothermic or brazed connection, and injecting a hardening material into one or more fill ports in the mold. The hardening material hardens to form the protective covering encasing the connection.

Abstract: A tool assembly for performing operations in confined spaces, the tool assembly includes a telescoping pole having a proximal end and a distal end. The telescoping pole is capable of extending between a retracted position and an extended position. A working tool is connected to the distal end of the telescoping pole, and a control unit is connected to the proximal end of the telescoping pole. A flexible cable extending through the telescoping pole electrically connects the working tool to the control unit.

The second portion of the working fluid circulates through the steam turbine assembly and the first heat exchanger. The first heat exchanger transfers a first heat energy from the gas turbine loop to the steam turbine loop. The gas turbine assembly generates a first portion of an electric output. The steam turbine assembly generates a second portion of the electric output.

Abstract: Synchronization technology is implemented for a satellite communication system. Master clock information is accessed at a terrestrial location. A timing message based on the master clock information is transmitted from the terrestrial location to a satellite as the satellite is in orbit. The satellite is synchronized to the master clock based on the timing message. A beacon signal is transmitted from the satellite toward Earth. The beacon signal includes timing information. The beacon signal is received at a ground based gateway. The gateway is synchronized to the satellite based on the beacon signal. Communication is sent from the gateway to a terminal via the satellite. The communication includes timing data. The terminal is synchronized to the gateway based on the timing data.

Abstract: Techniques are disclosed for providing a redundant telemetry transmission path on a spacecraft. The spacecraft includes a telemetry (TLM) transmitter having a modulation input coupled by a commandable switch with a signal source. The TLM transmitter is configured to receive an output from the signal source when the commandable switch is closed. The computer is configured to encode TLM data bits onto a TLM downlink signal by actuating the commandable switch, such that a signal from the signal source received by the TLM transmitter is temporally varied between an on condition and an off condition.
