Abstract: Various implementations disclosed herein include devices, systems, and methods that track a movement of an input device. For example, an example process may include determine a pose of a tracking device in a physical environment based on first sensor data from an image sensor. The process then may receive, from the tracking device, first positional data corresponding to a first relative positioning between the tracking device and an input device in the physical environment, where the first positional data is determined based on second sensor data obtained via a sensor on the tracking device. The process then may track movement of the input device in the physical environment based at least in part on the first positional data and the pose of the tracking device. The process then may determine an input for the electronic device based at least in part on tracking the movement of the input device.

Abstract: In-Place Cope Molding or “IPCM,” is designed to reduce or eliminate certain inefficiencies present in traditional molding techniques during production of the cope half of a sand mold. IPCM allows the cope half of the mold to be produced on top of the drag half of the mold by use of a separation barrier which supports the sand above the mold cavity in the drag. This method reduces or eliminates parting line flash, and also avoids the need to turn over or otherwise handle the cope, allowing the cope to be made thinner than a traditional cope and allowing for lower material costs.
