Abstract: In an embodiment, a roaster application may be provided. The roaster application may allow a roaster to create and customize coffee recipes. The roaster application may upload the recipes to a back-end server. Connected coffee machines may download the recipes and use the brew parameters in the downloaded recipes to more precisely replicate the roaster's recipe. In another embodiment, a hot brew coffee machine may be used to generate cold brew coffee. For example, a mechanical actuator such as centrifugal brewer assembly may be used to create a cold brew temperature in the coffee machine. The centrifugal brewer assembly may pull hot air out of the brewer assembly until the coffee machine reaches the desired cold brew temperature. Alternatively or additionally, cold water may be sprayed to the brewing mechanism to reach the desired cold brew temperature.

Abstract: Apparatus for dental simulation comprising: a display; one or more processors; a hand piece comprising a light emitter and an inertial measurement unit (IMU), wherein the IMU is in communication with at least one of the one or more processors, and wherein the IMU is configured to generate IMU position and orientation data, wherein the IMU position and orientation data describes the position and orientation of the hand piece; at least two cameras in communication with at least one of the one or more processors, wherein each of the at least two cameras is configured to generate a series of images using light emitted by the light emitter; wherein the one or more processors are configured to: receive the series of images from each of the at least two cameras, generate, based on two dimensional coordinate data derived from the series of images, three dimensional coordinate data identifying the position of the LED; receive the IMU position and orientation data; and further wherein the one or more processors are con
