A projection display apparatus includes a processing circuit and an image projection display device. The processing circuit is configured to perform a dynamic motion compensation based on two successive first frame and second frame in a first video signal, in order to generate a complement frame between the first frame and the second frame. The processing circuit is further configured to combine the first frame and the complement frame into a third frame, and to decompose the third frame to generate a plurality of fourth frames and to output the fourth frames as a second video signal. A resolution of the first video signal is higher than a resolution of the second video signal. The image projection display device is configured to project and display the second video signal, in which the imaging device has an original resolution equal to the resolution of the second video signal.

The present disclosure relates to an adapter. The adapter includes an input port (IN), a first output port (OUT1) and a second output port (OUT2), and the adapter further includes: a rectifier circuit (110) having an input terminal being connected to the input port (IN) of the adapter; a bus capacitor (120) connected to an output terminal of the rectifier circuit in parallel; a first flyback converter (131) having an input terminal connected to the bus capacitor and an output terminal coupled to the first output port (OUT1); and a second flyback converter (132) having an input terminal connected to the bus capacitor and an output terminal coupled to the second output port (OUT2).

A photovoltaic-inverter heat-dissipation assembly (1, 1a, 1b, 1c) is disclosure and includes a front housing-base (10), a rear cover (20), a first heat-generating device (32), a first fan (33), a second heat-generating device (42) and a second fan (43). The rear cover (20) and the front housing-base (10) are combined to separately form a first heat-dissipation space (31) and a second heat-dissipation space (41). The rear cover (20) includes a first air-inlet (311), a second air-inlet (411) and an air-outlet (312, 412). The first air-inlet (311) and the second air-inlet (411) are in communication with the air-outlet (312, 412) through the first heat-dissipation space (31) and the second heat-dissipation space (41), respectively. The first fan (33) generates a first airflow (F1), which enters through the first air-inlet (311), flows through the first heating-generating device (32) accommodated in the first heat-dissipation space (31), and flows out through the air-outlet (312). The second fan (43) generates a second airflow (F2), which enters through the second air-inlet (411), flows through the second heat-generating device (42) accommodated in the second heat-dissipation space (41), and flows out through the air-outlet (412).

An AC-DC power conversion system (400) provides extended voltage gain characteristic by virtue of controlling a duty cycle of operation associated with the desired input-to-output gain. The AC-DC power conversion system (400) includes an AC-stage, first and second inductors (L<1>, L<2>), first and second voltage-doubler stages (401a, 401b), a totem-pole rectifier stage (402), and a DC-stage (403) coupled across the totem-pole rectifier stage (402). Each voltage-doubler stage (401a, 401b) includes a first terminal, a second terminal, and a third terminal, wherein a first terminal of the AC-stage is coupled by the first inductor (L<1>) to the first terminal of each voltage-doubler stage (401a, 401b) and by the second inductor (L<2>) to the third terminal of each voltage-doubler stage (401a, 401b). The totem-pole rectifier stage (402) includes first and second terminals coupled, respectively, to the second terminal of the first voltage-doubler stage (401a) and the second terminal of the second voltage-doubler stage (401b).

The present disclosure provides a charging gun (100) including a cable (3), an outer casing (1) and a strain relief structure (2). The outer casing (1) includes a first case (11) and a second case (12), wherein the first case (11) is detachably assembled with the second case (12). The strain relief structure (2) includes a first portion (21), a second portion (22) and a plurality of first ring-shaped protrusions (23). The first portion (21) is detachably assembled with the second portion (22), the first portion (21) is disposed on the first case (11), and the second portion (22) is disposed on the second case (12). When the first case (11) is assembled and connected with the second case (12), the first portion (21) is assembled and connected with the second portion (22), and at least a part of a surface (31) of the cable (3) is covered by the strain relief structure (2), and the strain relief structure (2) is clamped between the cable (3) and the outer casing (1).

An airtight device includes a container and an airtight cover on the container, and the airtight cover includes a fixing bracket, a door, and a pressuring handle. The fixing bracket has a through hole and a guiding slot, and the through hole communicates with internal space of the container. The guiding slot has adjacent first and second top surfaces, and the second top surface is higher than the first top surface. The door selectively covers the through hole. The pressuring handle pivoted on the door has a first section, a second section, and a rotating axis between the first and second sections, and the first section rotates relative to the second section. The second section receives a force to drive the first section to move from below the second top surface to below the first top surface such that the rotating axis pressures the door.
