Patent number: 11780156Abstract: An extruder or other similar tool head of a three-dimensional printer is slidably mounted along a feedpath of build material so that the extruder can move into and out of contact with a build surface according to whether build material is being extruded. The extruder may be spring-biased against the forward feedpath so that the extruder remains above the build surface in the absence of applied forces, and then moves downward into a position for extrusion when build material is fed into the extruder. In another aspect, modular tool heads are disclosed that can be automatically coupled to and removed from the three-dimensional printer by a suitable robotics system. A tool crib may be provided to store multiple tool heads while not in use.Type: GrantFiled: March 9, 2022Date of Patent: October 10, 2023Assignee: Stratasys, Inc.Inventors: Peter Joseph Schmehl, Aljosa Kemperle, Stewart Schmehl

Publication number: 20230085702Abstract: A bean roasting system includes a roasting subsystem and an air handling subsystem. The roasting subsystem includes a housing, an agitator actuator, an agitator, a bearing and a door. The housing has an inner surface defining an inner chamber for holding a batch of beans during a thermal roasting process. The agitator is coupled to the agitator actuator and includes a central shaft and a blade set mounted to the central shaft. The bearing supports the central shaft and is configured to prevent the blade set from contacting the inner surface of the housing. The door has a transparent window to allow viewing of the thermal roasting process. The air handling system is coupled to the roasting subsystem, includes a blower and heater, and is configured to circulate heated air through the roasting subsystem during the thermal roasting process.Type: ApplicationFiled: September 23, 2021Publication date: March 23, 2023Inventors: Stewart SCHMEHL, John SANDHU

Publication number: 20160033221Abstract: An accessory device useful for any of training, compliance, safety, and accountability of individuals in the use of firearms. An embodiment comprises a circuit board and housing with a means for attaching the accessory to a firearm. The circuit board may comprise an inertial measurement unit (IMU), a GPS receiver, memory to store data, a means for transmitting data, and a microprocessor unit for controlling operations of the printed circuit board. The IMU may comprise a gyroscope, accelerometer, and magnetometer. The accessory can provide position and movement data of such accuracy as to disclose, after transmission and analysis, a firearm user's stability prior to and during discharge, how well the user managed recoil from the discharge, and how quickly the user returned to a starting position following discharge. A reviewer may also be able to discern movements such as those caused by a user's breathing or involuntary muscle contractions.Type: ApplicationFiled: March 14, 2014Publication date: February 4, 2016Inventors: Stewart Jacob SCHMEHL, Peter James HAMANN, Jacob Stewart SCHMEHL
