Abstract: In a file sharing system, a key manager unit realizes a correspondence between the first user identifier and the first public key in response to a registration request of the first user, generates a first key material for encrypting the first file into a first encrypted file, and generates a first credential according to the first user identifier, the first file identifier, the first public key and the first key material after receiving an access-right claim request to the first file from the first user. A file storage unit stores the first encrypted file and the first credential. The first user uses the first user identifier, the first file identifier and the first private key to retrieve the first key material out of the first credential, and uses the first key material to decrypt the first encrypted file into the first file.

Abstract: An image sensing device and a control device of an illumination device thereof are provided. The control device includes a control circuit, an operation circuit, and multiple driving signal generators. The control circuit generates multiple control signals. The operation circuit performs a logical operation on the control signals and an image capturing signal to generate multiple operation results. The driving signal generator respectively provides multiple driving signals to the illumination device according to the operation results, and the driving signals respectively have multiple different output powers.

Abstract: The present invention relates to a gas combustor, which comprises a housing in which a base seat is installed, an engagement pipe at the front of the base seat is connected to a flame device exposed at the front of the housing, wherein the rear portion of the base seat is pivoted with a swing sheet, the inner surface thereof is adjacent to a gas intake control valve fastened in the base seat, and a convey pipe is connected between the gas intake control valve and a pivotal connection device installed at the rear of the housing; and a safety mechanism, installed at the bottom of the housing and including a latch button, a connection rod and a control button; through pressing the latch button, one end of the connection rod is raised, the latch end at the other end of the connection rod is inwardly retracted for releasing the locking state of the control button, so the control button is enabled to be pressed, and the extrusion part extrudes the swing sheet, and the gas intake control valve is formed to an openin

Abstract: The present invention relates to a gas combustor, which comprises a storage tank, a connect seat allowing an ignition device and a combustion device to be installed, and a housing. The rear of the connection seat is formed with an accommodation slot in sequence allowing a piezoelectric device of the ignition device and a pressable button member to be installed and positioned, the front of the button member is protruded with a push sheet. Two clamp arms at the front of the connection seat define an insertion slot allowing an insertion tenon fixed at the rear of a mixing tube of the combustion device to be inserted and positioned, such that the mixing tube and the piezoelectric device are in contact.

Abstract: The present invention relates to a gas combustion apparatus, composed by a storage tank, a combustion gas setting device, an ignition device, a housing, a combustion device and an outer tube.

Abstract: The present invention relates to a hand-held gas combustion apparatus, comprises a gas storing tank, a gas discharging device, a housing, an ignition system and a flame device. The flame nozzle of the flame device and the metal sleeve tube are respectively in contact with the conductive wire and the electricity-guiding wire of the ignition system, so a static electricity spark is generated between the inner folding edge of the metal sleeve tube and the flame nozzle, so mixed combustion gas ejected from the flame nozzle is ignited, a gas combustion apparatus is therefore obtained, and the electricity-guiding wire is provided between the metal sleeve tube and the ignition system so the high-voltage static electricity can be guided back to the ignition system for forming a circuit.

Abstract: A safety structure of a gas burner is disclosed formed of a slide, a stop device and a housing. When pressed the slide, a third spring member is compressed to lower the stop device and to further disengage the retaining blocks of the stop device from respective retaining grooves of the slide, thereby releasing the stop device from the constraint of the slide. When the user keeps pressing the slide at this time, the retaining blocks are moved to a bottom side of the guide ribs of the slide and the frame base is forced to squeeze a first spring member to release the locked state.
