Provided are a fall detecting apparatus and method and an emergency aid system and method using the same. The fall detecting apparatus includes a storing unit configured to store fall data vectors; an angular velocity measuring unit configured to measure an angular velocity value; an acceleration measuring unit configured to measure an acceleration value; an acceleration extracting unit configured to extract a kinetic acceleration value and a gravitational acceleration value by filtering the acceleration value measured by the acceleration measuring unit; and a fall determining unit configured to convert the angular velocity value, which is measured by the angular velocity measuring unit, and the kinetic acceleration value and the gravitational acceleration value, which are extracted by the acceleration extracting unit, into a fall data vector, and determine a use's fall by comparing the converted fall data vector with the fall data vector stored in the storing unit.

Non-volatile flip-flops (NVFFs) based circuitries and schemes that incorporate magnetic tunnel junctions (MTJs) are provided to ensure fast data storage and restoration from an intentional or unintentional power outage. The NVFFs based circuitries and schemes also include enhanced scan mode testing capability by exploiting the nonvolatile latch to function as hold latch for delay testing. The NVFFs based circuitries and schemes eliminate additional write drivers, and may operate at an operation frequency of, for example, up to 2 GHz at a supply voltage of 1.1 V and with 0.55 pJ of energy consumption. A near uniform write latency can be achieved through transistor sizing, given write asymmetry of MTJs. NVFFs based circuitries and schemes incorporating data-dependent power gating circuitries can be used to mitigate high static currents generated during retention and back-to-back writing of identical input data.

A DC blocking device using impedance matching is disclosed. The disclosed DC blocking device comprises: a first strip line configured to receive a signal and including a first line section and a first joining section joined to a part where a signal is received; and a second strip line separated from the first strip line at a designated distance and including a second line section and a second joining section for joining an output signal, where coupling occurs from the first strip line to the second strip line, the first strip line and the second strip line each have at least one bending section, and the first line section and the second line section have smaller line widths than the first joining section and the second joining section. The disclosed DC blocking device has the advantage of minimizing spatial constraints when it is installed in a mobile communication apparatus, and of achieving proper coupling even if the length of the part of the DC blocking device where coupling occurs is reduced.

The present invention relates to a method of manufacturing thin-film transistors using nanoparticles and thin film transistors manufactured by the method. A hydrophilic buffer layers are deposited on the substrates to facilitate formation of nanoparticle films. Sintered nanoparticles are used as an active layer and dielectric materials of high dielectric coefficient are also used as a gate dielectric layer to form a top gate electrode on the gate dielectric layer, thereby enabling low-voltage operation and low-temperature fabrication.

Provided is a direct write patterning method utilizing a mixture comprising an ink of choice and an ink carrier matrix. The method involves disposing the mixture on a tip or stamp and transporting the mixture from the tip or stamp on a surface to form a pattern that contains the ink. The method does not require chemical or physical modification of either the tip or stamp or the surface prior to transporting the mixture to the surface. The method can be applied for patterning hard inks such as nanomaterials and crystallized polymers and soft inks such as biomaterials including peptides and proteins. Also provided are related biomaterial and hard ink arrays.
