Abstract: A method for controlling temperature in a liquid metal three-dimensional (3D) printing system is disclosed, including ejecting a liquid metal drop from a nozzle onto a deposition location to form a portion of a three-dimensional object. The method also includes measuring a temperature at a measurement spot location offset from the deposition location, and comparing the measured temperature with a set point temperature in the deposition location, adjusting a cooling rate of the liquid metal drop. The deposition follows a toolpath to form the portion of the three-dimensional object.

An additive manufacturing device configured to perform the method includes a printhead that includes a nozzle having an inner cavity, where the nozzle is configured for ejecting droplets of liquid metal drops to form a three-dimensional object.

Abstract: Embodiments are described that leverage commonly used HTML tags to enable the transfer of large quantities of data in a network. Embodiments are described where large amounts of data can be sent to a server by fragmenting data into small portions and encoding each portion as part of a URL contained in, for example, the src attribute of an <img> tag. The path of this URL can refer to a predetermined resource contained on the server that is responsible for retrieving fragments of data from the requested URL. Each fragment of data can be sent together with whatever additional pieces of information are required by the server to correctly reassemble the portions to obtain the original, defragmented data. Methods are described that enable a client to communicate an arbitrarily large amount of data to a server using only the GET method.

Abstract: A stapler movable between a rest position and a stapling position and having a front end and a rear end. The stapler includes a base, a staple magazine coupled to the base and configured to hold staples, and a driver blade operable to drive staples out of the staple magazine during stapling operations. The stapler further includes an elastic member coupled to the driver blade and operable to move the driver blade during stapling operations. The elastic member utilizes potential energy to move the driver blade during stapling operations. The driver blade is positioned above the staple magazine when the stapler is in the rest position and the magazine is extendable from the front end of the stapler to allow a user to load staples in the magazine. The stapler is configured such that only the potential energy of the elastic member can operate the driver blade during stapling operations.
