Abstract: A controller is provided. The controller is adapted to determine a position conversion relationship between a predetermined position of a body part of a user and a tracking position of a wearing part of the user. The wearing part is where a wearable device is disposed on the user. The controller is configured to: obtain a camera data of a previous moment from a camera, wherein the camera data comprises an image of a wearable device; obtain a sensor data of the previous moment from a sensor of the wearable device; determine the position conversion relationship based on the camera data of the previous moment and the sensor data of the previous moment; and output a fusion data of the wearing part of a current moment based on the position conversion relationship.

Abstract: The embodiments of the disclosure provide an object tracking method and a host. The method includes: determining a reference motion state based on a first predicted motion state and a calibration factor; obtaining a first motion data of the host and a second motion data of a reference object; determining a first relative pose of the reference object relative to the host based on the first motion data, the second motion data, and the reference motion state; and determining a specific pose of the reference object based on the first relative pose.

Abstract: A portable bioreactor is provided for driving displacement of at least one stirring sleeve relative to at least one tube cassette in a first direction and includes a machine frame unit and a first elevator. The first elevator includes a first linear movement module, a first transmission module, and a first turning module. The first linear movement module includes a first slider which is slidable on the first guide rail in the first direction between a first top position and a first bottom position. The first turning module is coupled to the first slider through the first transmission module so as to permit turning of the first turning module to be translated by the first transmission module into linear sliding movement of the first slider at a varying speed.

Abstract: A cartridge for a bioreactor adapted for accommodating a plurality of objects includes a cartridge main body defining a plurality of spaced-apart accommodating slots for respectively accommodating the objects therein. The cartridge main body includes a retaining portion extending into at least one of the accommodating slots, and adapted to retain a corresponding one of the objects in a corresponding one of the accommodating slots. The retaining portion is pushable to move resiliently in the corresponding one of the accommodating slots.

Abstract: A touch display device includes a display panel, a conductive layer on the display panel, an insulation layer on the conductive layer, and a touch panel on the insulation layer. The insulation layer has a first via. The touch panel includes a ground pad located at a peripheral region thereof The touch panel is connected to an external circuit through a flexible printed circuit board. The conductive layer is electrically connected to the ground pad through the first via of the insulation layer, but not directly connected to the flexible printed circuit board. A noise-shielding method for touch display device is also provided.
