A tripod support device includes a pivot seat unit (1), three support rods (201), each pivotably extending through the pivot seat unit (1) at a pivot portion to terminate at upper and lower end portions (22, 23). The upper end portions cooperatively define a carrying surface (S) when the support rods is in an unfolded state. A synchronizing seat (31) is disposed among the support rods (201) and movable relative to the pivot seat unit (1) along a central axis (L), and has a hub (301) and three linking protrusions (302). Three lower linking bars (34) are pivotably connected with the linking protrusions (302) and lower pivot portions (24) of the support rods (201) to turn the support rods (201) during movement of the synchronizing seat (31). In the unfolded state, the lengthwise axis (X1) of each lower linking bar (34) is offset from the central axis (L).

A hydrogen internal combustion engine (100) comprises one or more combustion units (10). Each combustion unit (10) includes a combustion chamber (11) configured to receive a mixture of hydrogen (H2) and oxygen containing gas (O2). An intake channel (12c) with an intake mechanism (12v) allows the oxygen containing gas to enter the combustion chamber (11). A compression mechanism (13) compresses the chamber volume, after which a fuel injector (14) injects hydrogen under pressure into the compressed volume. Combustion (CB) of the compressed hydrogen-oxygen mixture causes the chamber volume to expand, driving the compression mechanism (13). An exhaust channel (15c) with an exhaust mechanism (15v) allows discharge of the resulting combustion product (H2O). A catalytic ignition assembly (18) with catalytic material (C) promotes ignition (IG) of the compressed hydrogen-oxygen mixture to initiate combustion. This configuration may enable autoignition of hydrogen without requiring conventional ignition systems like spark plugs or pilot fuel.

The invention is aimed at providing a bioactive formulation suitable for printing, preferably 3D printing, the formulation comprises: a first and a second excipient and a bioactive substance that is easily interchangeable with either the first or second excipient. While heating and mixing the formulation a slurry comprising a matrix and a particulate matter is formed such that the formulation may have the required flowability during printing and the dimensional stability to create a final product.

A support system (100) comprises a base (10), a platform (30), and a scissor structure (20) configured to support the platform (30) with the external load (L) at an adjustable height (Z) above the base (10). The scissor structure (20) comprises a first pivotable arm (21) and a second pivotable arm (22), each having one stationary end portion pivotably mounted to a respective stationary hinge (13,33) and one moveable end portion pivotably mounted to a respective guided element (32,12). The guided elements are moveable along guidance directions (31d,11d) of respective guidance structures (31,11) on the platform (30) and base (10). A clamping mechanism (40) controllably fixates the adjustable height (Z) by clamping onto an elongate adjustment member (41) connected to a moveable portion (21u,221) of the scissor structure (20).

A wafer boat is disclosed. The wafer boat comprises two side rods and at least one back rod, the rods extending substantially vertically between a top member and a bottom member. The rods comprise vertically spaced apart support formed at corresponding heights, each support extending away from the respective boat rods towards a central axis of the wafer boat. Each support has a wafer support surface for contacting a wafer, the wafer support surface being a polished surface, and each wafer support surface is terminated by two rounded corners.

An example method includes generating, by a first device, an instruction or an alert; outputting, by the first device, a first output signal indicating the instruction or the alert; transmitting, by the first device to a second device, a communication signal indicating the instruction or the alert; and outputting, by the second device, a second output signal indicating the instruction or the alert. The second output signal has a common characteristic with the first output signal.

Methods are described for a wireless device to select a cell for registration. Information, shared with the wireless device, may provide details the wireless device may use to select a cell for registration. The information may provide the wireless device with details on which access technologies are available or unavailable, which are restricted or allowed, and/or which frequencies are available and/or their priority of use. Using the provided information, the wireless device may determine possible cells for selection, and based on measurements of the possible cells, the wireless device may select a cell for registration.

An atomization device includes: a housing, one end of the housing is provided with a first positioning portion; a main body mounted in the housing, an end portion of the main body is provided with a first fixing portion, a second fixing portion, and an operating portion, the first positioning portion and the first fixing portion being engaged with each other; and a bottom cover mounted on the end portion of the main body, the bottom cover is provided with a first locking portion and a second locking portion, the operating portion is engaged with the first locking portion, and the second fixing portion is engaged with the second locking portion. When the operating portion is operated to be separated from the first locking portion, the first positioning portion is separated from the first fixing portion, so as to separate the housing from the main body.

System for handling plants and/or plant pots, comprising a tray and an insert, wherein the tray is made of plastic and comprises a bottom and two opposite first side walls and two opposite second side walls, first and second side walls meeting at four corners of the tray and defining an upper rim extending along edges of the side walls opposite the bottom wall, wherein the upper rim is provided with at least two first connecting provisions and the insert is provided with at least two second connecting provisions, wherein each first connecting provision is designed for cooperation with one of the second connecting provisions, such that cooperating first and second coupling provisions are prevented from becoming uncoupled by pulling at the insert in a direction parallel to a main plane of the bottom wall, inward to the tray.

An access point may communicate with a wireless device. Different network devices of the access point may use two different power levels (e.g., lower and higher power levels) for communication. A spectrum in a frequency band may be split into multiple sub-spectrums (e.g., channels) that may operate at different power levels. For example, a first sub-spectrum (e.g., channel) may be used for a lower power level and/or a second sub-spectrum (e.g., channel) may be used for a higher power level. The wireless device may determine which power level to use to connect to the access point.
