摘要:
A buoyancy device has a rear buoyancy area interconnected to a pair of lateral under arm buoyancy areas by a pair of front buoyancy areas, and combining to form a simulated W-shape when viewed in a plan view. The provision of the lateral or underarm buoyancy areas function to hold the user more upright and normally higher above the level of the water when in use.

A combined casing and mounting assembly for a descent device to be contained by the assembly when not in use and to be suspended from the assembly when in use includes an enclosed hollow casing which has a rear panel to be fixed to a wall of a building, a side panel having one edge hinged to the rear panel, and a cover panel hinged to another edge of the side panel opposite the rear panel. The side panel and the cover panel can be turned from an enclosing storage position relative to the rear panel to an open position in which the cover panel extends through an opening in the wall. The descent device is to be suspended from the cover panel of the assembly when in use. The assembly further includes a positioning device to maintain the cover panel in the openn position and a fastening device to maintain the cover panel in the storage position.

摘要:
A sensing method for an improved sensing module comprises the steps of: (1) determining whether a sensed object is the same to previous one; (2) collecting sensed signals by using a sensor; (3) processing the sensed signals to produce sensed data through a central processor; (4) determining whether a moment to transmit the sensed data is approached; (5) capturing and transmitting the sensed data; (6) receiving the sensed data by a computer of an end user; (7) writing the sensed data into a flash memory; (8) determining whether the flash memory is full, if so, going to step (5), otherwise, going to step (2); and (9) updating the data in an API by the end user for executing step (2).
摘要:
A knuckle joint in which a first piece with an eye enters a jaw between two corresponding projections of a second piece having a first and a second eye respectively formed therein, and is retained by a pin member, wherein the pin member comprises a pin having a first end with a button fixed thereat and a second end. The pin passes through the eye of the first piece, which then retractably protrudes the button out from the first eye of the second piece and extends the second end to a position near the second eye of the second piece. A stopper has a protrusion which is passed through the second eye of the second piece, extending into the eye of the first piece, and joined with the second end of the pin. A slide block is passed through by the pin and inserted within the eye of the first piece, retractably protruding into the first eye of the second piece. The knuckle joint can be pivotally rotated while the button is depressed to push the protrusion of the stopper out from the eye of the first piece and to push the slide block out from the first eye of the second piece.

A low power wireless sensing system includes: a sensing device senses a peripheral environment to generate sensing data; a transmission device, coupled to the sensing device, is connected to an external network through a communication protocol to establish a wireless sensing network; a storage device stores the sensing data or first firmware; and a microprocessing device generates a control signal to control operations of the sensing device, transmission device and storage device according to the sensing data or a RF signal of the external network. The microprocessing device determines to read the first firmware according to the RF signal, so that second firmware built in the microprocessing device is updated and the control signal is adjusted correspondingly. The microprocessing device makes the transmission device enter a sleep state or perform reconnecting according to the RF signal.

摘要:
A device for positioning a rotary member at a desired angle relative to a fixed member includes a first shaft sleeve mounted in the rotary member, and a second shaft sleeve mounted in the fixed member adjacent to and axially aligned with the first shaft sleeve. The first and second shaft sleeves have a plurality of inward and axially extending clutch teeth notches. A shaft member has a first section slidably mounted in and extending through the first shaft sleeve, a second section slidably disposed in the second shaft sleeve, and a central section connecting the first and second sections and having a plurality of axially extending and outwardly projecting clutch teeth protrusions. The shaft member is slidable between the first and second shaft sleeves to interengage or disengage the first and second shaft sleeves. The central section is moved towards the first shaft sleeve to disengage the central section from the second shaft sleeve, and towards the second shaft sleeve to engage the central section and the second shaft sleeve.
