A non-volatile resistive switching memory that includes a homogeneous material which changes between the insulative and conductive states due to correlations between electrons, particularly via a Mott transition. The material is crystallized into the conductive state and does not require electroforming.

Disclosed herein is a plexus of filaments which is composed of paired filaments which travel extensively around one another to form a double helix structure, where each pair of filaments belongs to a group of filaments, traverse at crossing angles to other filaments which belong to at least another group of filaments, thus repetitively crossing the paths of the filament pairs in at least another group of filaments. Also defined within the specifications and claims herein is the linking of the filaments between the different paired groups of filaments, which facilitates the distribution of tension between the filaments within a plexus of filaments. Herein described are plexuses which exhibit greater conformal and constrictive qualities in comparison to the prior art. Also disclosed is a method of producing filament structures for a variety of uses including composite structures, with enhanced structural properties, including but not limited to; tension displacement properties, for use in applications requiring conformal load distribution with minimal weight.

An unmanned aerial vehicle adapted for hover and short/vertical take-off and landing (S/VTOL) is disclosed. The vehicle comprises: a body having an aspect-ratio less than two and having therein a payload volume, at least one propeller located forward of the body, at least one rudder. The body may have an inverse Zimmerman planform which provides lift as air flows across the body in horizontal flight/fixed wing mode, and further adapted such that during hover and/or short/vertical take-off and landing (S/VTOL) the vehicle operates as a rotorcraft with the body oriented with the at least one propeller substantially above the body. The vehicle is suited to a method of inspection, such as power line inspection where large distances can be analysed efficiently by flying in fixed wing mode, but by transitioning to hover mode allows detailed inspection of selected areas.

The invention discloses a myoelectric feedback control electric stimulation device and a control method thereof, relating to the field of medical instruments. The control method comprises the steps of: collecting a myoelectric signal of a tested object; transmitting the myoelectric signal to a myoelectric signal amplifying unit; converting the myoelectric signal into a digital myoelectric signal; transmitting the digital myoelectric signal to a signal processing and controlling unit; calculating the myoelectric amplitude of the digital myoelectric signal; obtaining the myoelectric amplitude; and judging whether the myoelectric amplitude equals to the optimal myoelectric amplitude; if yes, not changing a stimulation mode, generating a stimulation waveform of the stimulation mode by an electric stimulation generating unit, and carrying out stimulant therapy on the tested object through stimulating electrodes; and if not, adjusting the stimulation mode by the electric stimulation generating unit and the signal processing and controlling unit, using the adjusted stimulation mode as a stimulation mode for the next time, generating a stimulation waveform of the stimulation mode, and carrying out stimulant therapy on the tested object through the stimulating electrodes. According to the myoelectric feedback control electric stimulation device and the control method thereof, the purpose of achieving the optimal stimulation effect in different stimulation modes is realized through adjustment of the stimulation mode.

Finally, the medlar and red date enzyme with high biological activity, strong stability, strong taste, flavor and appetite, long expiration date and edible safety is prepared.

Non-pneumatic resilient wheel (10), that is supported structurally and defines three perpendicular directions, circumferential (X), axial (Y) and radial (Z), this wheel comprising: a hub (11); an annular band referred to as a shear band (13) comprising at least one inner circumferential membrane (14) and one outer circumferential membrane (16) that are oriented in the circumferential direction X; and a plurality of support elements (12) that connect the hub (11) to the inner circumferential membrane (14)U. The two membranes (14, 16) are connected to one another by means of a series, that extends in the circumferential direction (X), of cylinders (15) referred to as connection cylinders, said connection cylinders (15) being non-touching in the circumferential direction X and having their generatrix oriented in the axial direction Y. The connection cylinders (15) are composite cylinders comprising fibres embedded in a resin matrix.

A high endurance, short retention NAND memory is used as a read cache for a memory of a higher level of non-volatility, such as standard NAND flash memory or a hard drive. The combined memory system identifies frequently read logical addresses of the main non-volatile memory or specific read sequences and stores the corresponding data in cache NAND to accelerate host reads. This may also reduce host's DRAM requirements. In some arrangements, special commands or partitions can be used by operating system to identify these fast read areas. The main non-volatile memory will typically also maintain a back-up copy of data in the cache NAND. In some embodiments, the read cache can be implemented as a middle layer between the host and storage system, say as an SATA-SATA bridge dongle to boost read access for frequently read data or specific patterns, such as a boot sequence.

Phase change based memory devices and methods for operating such devices described herein overcome the set or reset failure mode and result in improved endurance, reliability and data storage performance. A high current repair operation is carried out in response to a set or reset failure of a phase change memory cell. The higher current repair operation can provide a sufficient amount of energy to reverse compositional changes in the phase change material which can occur after repeated set and reset operations. By reversing these compositional changes, the techniques described herein can recover a memory cell which experienced a set or reset failure, thereby extending the endurance of the memory cell. In doing so, phase change based memory devices and methods for operating such devices are provided which have high cycle endurance.

An air vehicle assembly and a corresponding method for launching an air vehicle assembly are provided, along with corresponding control systems and methods. The air vehicle assembly may include a plurality of air vehicles releasably joined to one another during a portion of the flight, such as during take-off and landing. By being releasably joined to one another, such as during take-off and landing, the air vehicles can rely upon and assist one another during the vertical take-off and landing while being designed to have a greater range and higher endurance following the transition to forward flight, either while remaining coupled to or following separation from the other air vehicles. By taking into account the states of the other air vehicles, the control system and method also permit the air vehicles of an air vehicle assembly to collaborate.
