Abstract: A method is provided that can include activating at least two wireless communication channels in parallel, between a first wireless transceiver and a second wireless transceiver. Each of the at least two wireless communication channels can operate at a different radio carrier frequency, and the first wireless transceiver may be part of a first vehicle. The method can also include transmitting, by the first wireless transceiver, common information in parallel on the at least two wireless communication channels to the second wireless transceiver and deactivating the at least two wireless communication channels.

Abstract: A pump system for controlling a pressure load delivered to an aircraft interface included in the pump system is disclosed. The pump system includes a pump circuit, a pump, and a valve system. The pump is coupled with the conduits and is configured to provide a pressure load to the aircraft interface to move fuel from a fuel reservoir through the conduits toward the aircraft interface in a fueling mode and to move fuel from the aircraft interface through the conduits toward the fuel reservoir in a defueling mode. The valve system is coupled to the conduits and configured to control the pressure load delivered to the aircraft interface to block the pressure load from exceeding either of a high-pressure threshold and a delta-pressure threshold.

Abstract: Methods and systems for delivering voltage limited neurostimulation to a patient. In one aspect, a method includes initiating a flow of electrical current through a first electrode and a second electrode coupled to the patient and increasing the flow of electrical current toward a target value by increasing a voltage across the first electrode and second electrode. Prior to reaching the target value of electrical current, the method includes preventing the voltage across the first electrode and second electrode from increasing beyond a first predetermined limit; and subsequently, maintaining the voltage across the first electrode and second electrode at or within a predetermined range that does not exceed the first predetermined limit. The amplitude of the electrical current continues to increase toward the target value during at least part of a time when the voltage across the first electrode and the second electrode is maintained within the predetermined range.

Abstract: A heat pump has a refrigerant loop, a compressor in fluid communication with the refrigerant loop, at least one indoor heat exchanger in fluid communication with the refrigerant loop, and at least one outdoor heat exchanger in fluid communication with the refrigerant loop. The at least one outdoor heat exchanger has a phase change material in thermal communication with the refrigerant loop and in fluid communication with an outdoor environment. Other systems, devices, and methods are described.

Abstract: Rope made of cellulose fibers, the polymeric chemical structure of which fibers has not been modified (referred to as “raw” cellulose fibers), are subjected to intense electron beam irradiation insufficient to degrade their chemical structure but sufficient to modify their physical structure so as to allow them to be comminuted into fragments having a length no more than 6.35 mm (0.25?), preferably less than 3.175 mm (0.125?), and preferably 50% by weight of the fibers have a length less than 70 ?m. Such fragments of fibers are found to be particularly susceptible to being micronized in a micronizer into elongated granular fragments smaller than about 20 ?m at an economical production rate in excess of 22.7 Kg/hr (50 lb/hr) which was not possible when the micronizer was fed with naturally occurring fibers.

Abstract: Video and audio signals are streamed to remote viewers that are connected to a communication network. A host server receives an originating video and audio signal that may arrive from a single source or from a plurality of independent sources. The host server provides any combination of the originating video and audio signals to viewers connected to a communication network. A viewer requests the host server provide a combination of video and audio signals from the host server. The host server transmits an instruction set to be executed by the viewer. The instruction set causes the viewer to transmit parameters to the host user, including parameters relating to the processing capabilities of the viewer. The host server then transmits multimedia data to the viewer according to the received parameters. A plurality of viewers may be simultaneously connected to the host server.

Abstract: A retractable mold protrusion assembly for thermoforming parts is disclosed which is both self-contained and self-operating. The assembly includes a housing, a protrusion molding member moveably mounted to the housing, and an offset mounted spring. The protrusion molding member is movable with respect to the housing between a locked configuration and a pivoting configuration. When in its locked configuration, the protrusion molding member is securely held in a protruding position in which it protrudes away from the housing. In this position, a piece may be molded about the protrusion molding member to form a desired protrusion in the piece being formed. After molding has been completed, the removal of the molded piece slides the protrusion molding member into a second pivoting configuration, in which the protrusion molding member is pivotable into the housing to allow the molded piece to be completely removed.
