Abstract: It discloses an acoustic channel-based data communications method which performs channel coding on an original data signal using a CRC coding method and a BCH coding method to obtain a coded sequence; modulates the coded sequence using a preset audio sequence symbol set via a symbol mapping method to obtain a digital audio signal; selects a channel frequency band according to characteristics of a transmitting equipment and interference between frequency bands; and converts the digital audio signal into an analog audio signal through a digital-to-analog converter and transmits the signal to a channel for transmission according to the selected channel frequency band.

Abstract: LED lamp beads with multiple light-emitting points comprising a certain number of luminous bodies and package resins; in which after at least two luminous bodies are connected in parallel, they are wrapped in a package resin and connected to an anode pin and a cathode pin inserted into the package resin. The present invention structure is simple and has a rational design. By using one-way conductive luminance on the LED luminous bodies, and using parallel and inverse parallel connections on multiple light-emitting points, control of the electric current direction is achieved, and thus the control of the operating modes of luminous bodies and the LED lamp beads with multiple light-emitting points is achieved.

Abstract: This invention is related to a bottle structure. At least an embedded slot is disposed on a bottle body. A positioning member is disposed on the opening of the embedded slot. The inner edge of the positioning member projects toward the inner side of the opening of the embedded slot to form a stop edge. An embedded fixing part may coordinate with a spirally fixed element to lock the bottle body to a bicycle body. An embedded block of the embedded fixing part is embedded into the embedded slot of the bottle body and against the stop edge of the positioning member. A lug connected the bottom of the embedded block is located against positioning bumps disposed on inner edges of the positioning member to stably install the bottle body on the bicycle body.

Abstract: An adjustable tablet device holder includes a holder body including an arched sliding slot located in the back side and a locating plate extended from the back side adjacent to the arched sliding slot, and an adjustment mechanism including a turnable mounted in the holder body and having a position-limit rod extended out of the arched sliding slot and movable between the two ends of the arched sliding slot to rotate the turnable and lockable to the locating plate by a lock to stop the turntable from rotation and four clamping plates vertically and horizontally mounted in four sides and defining a clamping space for holding a mobile tablet device and movable inwardly and outwardly to adjust the horizontal width and vertical height of the clamping space upon rotation of the turnable.

Abstract: Disclosed are a filter element and a filter device using the filter element. The filter element includes: a base, wherein the base is installed on the filter device, and a first passage and a second passage are disposed at least partially in the base; and a filter body, wherein the filter body is detachably connected to an upper part of the base, the filter body has a filter space therein, a first filter passage and a second filter passage are connected and arranged on the two ends of the filter space, and a filter material for filtration is provided in the filter space. When the filter element is in a working state, the first filter passage and the first passage are connected for fluid communication, and the second filter passage and the second passage are connected for fluid communication.

Abstract: An adjustable dual-screen monitor stand includes a base member having an upright post, an upper bushing and a lower bushing mounted on the upright post at different elevations, a first cantilever swivel screen mount including a first lower swivel arm, a first upper swivel arm and a first screen holder pivotally coupled to one another and pivotally supported on the upper bushing to hold a first flat display monitor and to allow adjustment of the angular position of the supported first flat display monitor, and a second cantilever swivel screen mount including a second lower swivel arm, a second upper swivel arm and a second screen holder pivotally coupled to one another and pivotally supported on the lower bushing to hold a second flat display monitor and to allow adjustment of the angular position of the supported second flat display monitor.

Abstract: A lift-cord guide for window blind is disclosed to include a roller holder including a pull cord inlet and a pull cord outlet extending in a perpendicular manner relative to the pull cord inlet, and a first guide roller rotatably mounted in the roller holder at the intersection between the extending direction of the pull cord inlet and the extending direction of the pull cord outlet. The axial direction of the first guide roller obliquely intersects with the extending direction of the pull cord inlet, and defines with the extending direction of the pull cord outlet a contained angle smaller than 90-degrees. Thus, the lift-cord guide of the invention effectively reduces the turning angle of the pull cords, and smoothens the operation to open or close the blind slats.
