Abstract: A mounting device for adjustably mounting hardware equipment to a mounting structure is provided. The mounting device may include one or more rails coupled to at least one side of the mountable hardware equipment, wherein each of the one or more rails includes a plurality of stop areas with one or more stop surfaces; one or more mounting ears that each comprise a mounting pin; and a latch comprising one or more stop parts. The latch may be configured to cause the one or more stop parts to interface with the one or more stop surfaces, arresting the position of the mountable hardware equipment. By applying pressure to the latch, it can compress and slide to a desired installation depth. When pressure is released, the latch can expand in a vertical direction and engage the stop parts with the stop surfaces to fix the hardware in position.

Abstract: This disclosure provides an oxidation-resistant carbon-carbon composite that is molecularly inhibited with uniformly dispersed carbides. Nanoparticles of refractory metals and/or semi-metals suspended in a colloidal suspension infiltrate pores of a carbon-carbon composite during an initial pre-impregnation stage or carbon densification stage. The carbon-carbon composite is heated to form carbides that provide molecular level inhibition in both the interbundle and intrabundle matrix. The carbides are configured to form glass that serves as an oxidation barrier for the carbon-carbon composite. The carbon-carbon composite may be coated with external coatings that can include a converted silicon carbide, functionally graded material (FGM) ceramic coating, metallic coating, polymer-based coating, as-cured or low-temperature heat-treated sealant, or combinations thereof.

Abstract: Laminated carbon-carbon composites can be used as an ablative material, but they are often prone to delamination under thermally induced interlaminar shear and tension. Graded carbon-carbon composites with a sacrificial or ablative layer that is integral with one or more underlying layers and not fully dense can address these issues and provide other advantages. Such graded carbon-carbon composites can include a densified base layer containing a first portion of a carbonaceous matrix, and an outer ablative layer that is integral with the densified base layer and contains a second portion of the carbonaceous matrix. The carbonaceous matrix in the densified base layer has a first porosity, and the carbonaceous matrix in the outer ablative layer has a second porosity that is higher than that of the densified base layer. Methods for forming graded carbon-carbon composites can include heating a partially densified base layer and a carbonaceous matrix precursor above a carbonization temperature.

Abstract: A charging system and method for an electronic device controlled by audio output are used for controlling an external charging power supply to charge the electronic device. An electric quantity detection software runs on the electronic device, for detecting an electric quantity of the electronic device and generating audio signals indicating a message of performing a charging operation or a message of stopping the charging operation. An audio output interface is disposed on the electronic device for outputting the audio signals. A decoding device is connected to the audio output interface for receiving the audio signal and controlling the external charging power supply to perform the charging operation or to stop the charging operation on the electronic device. The charging system and method for the electronic device can effectively control the electric quantity of the electronic device, without requiring any charging control circuits.
