Abstract: A neuron circuit and an operating method thereof are disclosed. The neuron circuit may include an input unit to which an input pulse is applied, a bipolar memristor configured to have one end connected to one end of the input unit, a first capacitor configured to be connected between the one end of the bipolar memristor and a ground, a first diode configured to have an anode connected to the one end of the bipolar component, a second capacitor configured to have one end connected to a cathode of the first diode, a first switch configured to be connected between the one end of the second capacitor and the ground, and a second switch configured to be connected between the anode of the first diode and the other end of the second capacitor.

Abstract: Disclosed are a MEMS gas sensor and a manufacturing method thereof. The MEMS gas sensor includes a substrate having a recess, a membrane disposed in the recess and having a through-hole configured to expose a portion of a top surface of the substrate, which is disposed at a central portion of the recess, sensing electrodes disposed in the membrane, and a sensing layer disposed on each of bottom and top surfaces of the membrane and disposed in the through-hole.

Abstract: Disclosed is a multi-purpose sectional sports apparatus. The sports apparatus includes a plurality of assembling poles each including a main pole and a sub pole, a connector, and a supporting unit. The main pole has an insertion bore, an L-shaped lower fixture and a plurality of main coupling holes in an upper portion thereof. The sub pole is inserted into the main pole and has a plurality of lower height-adjusting holes and a plurality of upper sub coupling holes. The sub pole is movable up and down to have an adjustable height relative to the main pole as a fastener is fastened through selected ones of the height-adjusting holes and main coupling holes. The connector includes a branched body having a plurality of insertion branches for connection of the assembling poles, each insertion branch having an opening and an insertion bore.
