Abstract: To realize both toughness and size reduction of a safety switch. A safety switch is a safety switch into and from which a bolt of an actuator is inserted and pulled out. The safety switch includes a casing having a shape elongated along a first direction, a metal head having a receiving space for receiving the bolt of the actuator and provided on a first end side of the casing in the first direction, a detector for detecting a first state in which the bolt is received in the receiving space, a lock mechanism, a switching device and a first attachment portion provided in the head and having a first attachment hole into which a first attachment member is inserted.

Abstract: A display device includes pixels including a light-emitting element, and an initialization transistor connected between an anode electrode of the light-emitting element and a first initialization power line to which a voltage of initialization power is supplied, and turned on when an initialization scan signal is supplied, and an initialization scan driver which supplies the initialization scan signal. The initial scan driver supplies an i-th (i is a natural number) initial scan signal to overlap an (i?1)-th initial scan signal, and supplies an (i+1)-th initial scan signal so as not to overlap the i-th initial scan signal, and the initialization scan signal is set to a gate-on voltage.

Abstract: A liquid crystal display includes a display substrate which includes a plurality of pixel areas and is curved in a first direction, an opposite substrate which faces the display substrate, is coupled to the display substrate, and is curved along the display substrate, and a liquid crystal layer disposed between the display substrate and the opposite substrate, where a plurality of domains are defined in each of the plurality of pixel areas, directions in which liquid crystal molecules of the liquid crystal layer are aligned are different from each other in at least two domains among the plurality of domains, and the plurality of domains is arranged in a second direction crossing the first direction.

Abstract: An optical subassembly for switchably focusing or redirecting a light beam may include a polarization element having a polarization-selective beam redirection/focusing property, a first switchable polarization rotator upstream of the polarization element, and a second switchable polarization rotator downstream of the polarization element. A polarizer may be provided immediately downstream of the second switchable polarization rotator. The first and second switchable polarization rotators may be operated in counterphase, so as to mutually offset dependence of angle and wavelength characteristics of the polarization rotators on the switching state of the polarization rotators.

Abstract: A method provides for reducing interlink interference between an access point (AP) multi-link device (MLD) having a simultaneous transmit and receive (STR) link set and a non-AP MLD with a non-STR link set. The method includes transmitting data, by the AP MLD, to the non-AP MLD on a first link, simultaneously receiving data, by the AP MLD from the non-AP MLD, on a second link, and aligning, by the AP MLD, an end time of transmitted physical layer protocol data units (PPDUs) using padding in response to concurrently transmitting another PPDU, by the non-AP MLD, on a link that is part of the non-STR link set.

Abstract: According to example embodiments, a light emitting display device includes a transistor, a driving voltage line, a driving voltage connecting electrode, an initialization control line, an output current passing region, and a shielding layer, wherein the initialization control line is disposed on one side of a channel of the transistor in a plan view of the output current passing region and overlaps the shielding layer, and the shielding layer is connected to the driving voltage line through the driving voltage connecting electrode.

Abstract: A stabilizer bar bushing assembly is provided, in which even though it is exposed to heat of high temperature for a long time period the bracket is not dislocated from the rubber because the bracket is attached to the rubber integrally. The stabilizer bar bushing assembly comprises: an upper body including an upper rubber formed with a first concave groove and an upper bracket enclosing an outer surface of the upper rubber and bonded integrally to the upper rubber; a lower body including a lower rubber formed with a second concave groove and a lower bracket enclosing an outer circumferential surface of the lower rubber and bonded integrally to the lower rubber; and a coupling means for coupling the upper bracket and the lower bracket together in a state of installing the upper body and the lower body on the stabilizer bar.

Abstract: Disclosed herein is a battery system, including: an airtight housing; a plurality of blowers disposed on a front portion and a rear portion of an interior of the airtight housing, respectively, the plurality of blowers configured to suction and discharge the air toward a middle of the airtight housing and to discharge and to suction the air to both sides of the airtight housing; a battery pack disposed between the plurality of blowers to form a plurality of rows wherein an air passageway traverses through a front portion and a rear portion of each row; a mixing section disposed between the plurality of rows in the middle of the airtight housing is configured to mix air; and a thermoelectric element disposed on an air flow path on both sides of each blower.

Abstract: Disclosed is a constant discharge structure for a nozzle head lowering type vacuum cosmetics container for containing high functional cosmetics.
