Abstract: In a general aspect, a handheld controller device includes a housing and a trigger assembly. The housing is configured to be held in the hands of a user. The trigger assembly includes a pair of triggers extending outward from a side of the handheld controller device and configured to move along respective trigger paths. The trigger assembly also includes a guide and coupling assemblies. The guide assembly is disposed inside the housing and includes, for each trigger, a channel that extends at least partially along the trigger path of the trigger. The coupling assembly is disposed inside the housing and is connected to the pair of triggers. The coupling assembly is configured to transfer motion between the pair of triggers such that, when one trigger moves towards the housing along its respective trigger path, the coupling assembly moves the other trigger away from the housing along its trigger path.

A coupling assembly is disposed inside the housing and connected to the pair of triggers. The coupling assembly is configured to transfer motion between the pair of triggers such that, when either of the triggers moves towards the housing along its respective trigger path, the coupling assembly moves the other trigger an equal distance away from the housing along its trigger path. Circuitry in the housing includes one or more sensors and a microcontroller configured to receive sensor signals and, in response, generate aircraft control data (e.g., for a flight simulation or remotely controlled flyable aircraft).

Abstract: In a general aspect, a computer resource runs computer code from one or more cells of a spreadsheet. In some aspects, a spreadsheet application detects computer program script stored in a cell of an electronic spreadsheet document. A computer resource is then identified to execute the computer program script (e.g., based on a computer programming language of the computer program script). The computer resource is invoked to execute the computer program script, and the computer resource generates output data by executing the computer program script. The output data are converted to cell values for the electronic spreadsheet document, and the spreadsheet application populates the cell values into one or more cells of the electronic spreadsheet document.

Abstract: Phosphorus mud and other phosphorus-containing waste materials are processed to remove water and phosphorus and to leave a solid mass which is safe for disposal. The phosphorus mud is heated to boil off the water and then to boil off yellow phosphorus, which is subsequently condensed. The residual phosphorus then is removed mainly by burning off in air along with some volatilization, so as to increase the recovery rate of solids from the waste material, when compared to removal of residual phosphorus by volatilization under nitrogen. A significant improvement in processing rate is achieved at the expense of a loss of a minor amount of recoverable phosphorus.
