Abstract: A gravitational liquid-splitting device has a funnel, a dispensing valve, a liquid-splitting part, and a stirring assembly. The funnel has an inner space and a bottom opening connected to each other. The dispensing valve is mounted to the funnel and is configured to close or open the bottom opening of the funnel. The liquid-splitting part is connected to a bottom of the funnel and has an input channel and two output channels. The input channel is formed in the liquid-splitting part and extends upward and downward. An upper end of the input channel forms an input opening on a top of the liquid-splitting part and is connected to the bottom opening of the funnel. The stirring assembly has a stirrer configured to stir liquid in the funnel. Therefore, the gravitational liquid-splitting device improves efficiency and quality, and also reduces risk of contamination in the cell passaging operation.

Abstract: A cryopreservation cartridge has a frame and multiple cryopreservation trays. The frame has multiple mounting walls. Any two of the mounting walls have multiple tray shelf segments formed therebetween. The cryopreservation trays are respectively and detachably mounted on the tray shelf segments. Each of the cryopreservation trays has multiple cryovial mounting holes. Each of the cryovial mounting holes is adapted to load a cryovial. The cryopreservation cartridge is assembled by a frame and multiple cryopreservation trays so that one cryopreservation tray can be detached from the frame and held by a picker and then a mechanical arm can easily access any single cryovial loaded in the cryopreservation tray, thereby facilitating process of placing in or taking out the cryovial for automatic operation of cell cryopreservation and thawing.

Abstract: A control method for a first device of an inter-integrated circuit (I2C) system including a microcontroller unit (MCU), includes receiving a first indication from the MCU of the I2C system, wherein the first indication configures the first device from a slave mode to a master mode; polling the first device itself for status information of the first device when the first device is in the master mode; determining whether the status information of the first device matches a target status after polling; and determining to perform a parameter adjustment on a second device of the I2C system when determining that the status information of the first device matches the target status.

Abstract: An amplifier with adjustable gain including a plurality of differential amplifiers and an output stage circuit is provided. Each of the differential amplifiers has at least one differential pair, two current terminals of each of the differential pairs are coupled by a connection structure, and the connection structure provides a negative feedback resistance. The differential amplifiers commonly receive a differential input signal pair, and output terminals of the differential amplifiers are coupled together. The output stage circuit inverts a voltage on the output terminals of the differential amplifiers to generate an output voltage. A direct current gain of the amplifier with adjustable gain is determined by adjusting at least one of working numbers of the differential amplifiers and the differential pairs.

Abstract: A method for generating masking image using general polygonal mask includes receiving a pixel of a raw image and a polygon vertices array corresponding to a polygonal mask, determining whether the pixel is inside the polygonal mask, labeling the pixel to be a masked pixel if the pixel is inside the polygonal mask, or labeling the pixel to be a visible pixel if the pixel is outside the polygonal mask, and outputting the masked pixel or the visible pixel to generate the masking image.

Abstract: A semiconductor manufacturing execution system (MES) is disclosed, including a memory module, a comparing module, and an outputting module. The memory module stores a basic database and a recipe distribution management (RDM) database. The basic database includes multiple basic records, and the RDM database includes multiple RDM records. The comparing module compares operation data, received from a manufacturing machine, to each of the RDM records, and secondarily to each of the basic records, to determine whether the operation data matches at least one of the RDM and basic records. The outputting module outputs a limiting signal to the manufacturing machine if the operation data matches at least one of the RDM records. The limiting signal prevents the manufacturing machine from executing a process corresponding to the operation data.

Abstract: A manufacturing execution system (MES) is disclosed including a first database and a second database. The first database (e.g., a basic database) stores a first set of records, wherein each of the first set of records includes information regarding a routine operation to be performed on at least one semiconductor wafer when the at least one semiconductor wafer is positioned within a process tool. The second database (e.g., a special engineer requirement, or SER, database) stores a second set of records, wherein each of the second set of records includes information regarding a special operation to be performed on the at least one semiconductor wafer when positioned within the process tool. A method is also described, which may be embodied within the MES. The method includes receiving operation data from the process tool, wherein the operation data includes information regarding a selected operation (e.g., a user-selected recipe) to be performed within the process tool.
