A packet switch router that processes downstream digital information to provide dedicated bandwidth to each subscriber destination in a hybrid fiber coax (HFC) network. The router includes a network module that terminates a network connection, a switch that forwards data from the network module, and a channel module. The channel module includes a switch interface, a cell processing engine, one or more modulators, and a radio frequency (RF) transmitter network. The switch interface forwards packetized data from the switch to the cell processing engine. The cell processing engine organizes the packetized data into multiple data streams, encapsulates data in each data stream into data cells, and multiplexes the data cells into a multiplexed cell stream. Each modulator is configured to modulate a multiplexed cell stream into an analog signal. The RF transmitter network up converts and combines a plurality of analog signals into a combined electrical signal for transmission.

The apparatus include devices and mechanisms for isolating the treatment chambers from the ambient environment. The methods and apparatus may be adapted to control metalloid vapor delivery in photovoltaic cell processing, for example, the processing of CIGS and CIGSS photovoltaic cells.

The present invention generally provides an apparatus and a method for automatically calibrating the placement of fragile substrates into a substrate carrier. Embodiments of the present invention also provide an apparatus and a method for inspecting the fragile substrates prior to processing to prevent damaged substrates from being further processed or broken in subsequent transferring steps. Embodiments of the invention also generally provide an apparatus and a method for determining the alignment and orientation substrates that are to be delivered into or removed from a substrate carrier. Embodiments of the invention further provide an apparatus and method for accurately positioning the substrate carrier for substrate loading. The substrate carriers are generally used to support a batch of substrates that are to be processed in a batch processing chamber.

The present disclosure provides a reagent cartridge configured for use in an automated multi-module cell processing environment.

Methods and apparatus for cell processors are disclosed. A policy module is loaded from a main memory of a cell processor into the local memory of a selected synergistic processing unit (SPU) under control of an SPU policy module manager (SPMM) running on the SPU. A selected one or more work queues are assigned from a main memory to a selected one or more of the SPUs according to a hierarchy of precedence. A policy module for the selected one or more work queues is loaded to the selected one or more SPUs. The policy module interprets the selected one or more of the selected one or more work queues. Under control of the policy module, work from one or more of the selected one or more work queues is loaded into the local memory of the selected SPU. The work is performed with the selected SPU. After completing the work or upon a pre-emption, control of the selected SPU is returned to the SPMM.

The wide combination of attributes not found in other membrane based cell culture and bioprocessing devices includes more cell capacity, more cell secreted product capacity, higher cell and product density, increased medium capacity, minimized use of exogenous growth factors, compatibility with standard cell culture equipment and protocols, increased scale up efficiency, capacity to function when rolling or standing still, capacity for perfusion without the need for pumps, and more efficient sample dialysis.

A method of making a reference control containing a nucleated red blood cell component includes providing a blood cell containing a nucleus; treating the blood cell with a treatment solution to alter a nucleus property from a natural value to a target value suitable for simulating nucleated red blood cells on a blood analyzer; and suspending treated blood cell in a suspension medium to form a reference control. The method also includes integrating the nucleated red blood cell component with white blood cell, red blood cell, platelet and reticulocyte components. Further disclosed is a cell treatment composition for altering a nucleus property, which includes a conditioning component, a lytic component for permeating cell membrane, and a fixing component for preserving the cell nucleus. Also disclosed is a method of using the reference control for measurement of nucleated red blood cells on a blood analyzer.

The invention is directed towards determining whether a hard handover should be performed of a mobile station (48) in relation to a first group of cells (16, 18, 20, 24) including a number of active cells (16, 18, 20) and handled by a first cell handling device (10) to a second group of cells (32, 36, 38) handled by a second cell handling device (26), when the cell handling devices lack a direct communication link (lur). Either the first cell handling device or the mobile station obtains measurements of link quality between the mobile station and cells of the groups, determines a first and second total quality factor for the groups, performs an evaluation of a preferred group involving comparing the first total quality factor with the second quality factor and initiates a handover from the first group to the second group if the second group is preferred.

A cell processing apparatus 29 of the present invention includes a storage container 57 that can contain liquid L including a biological sample; a filter 60 that prevents a first cell C1 in the biological sample from passing therethrough and that allows a second cell C2 having a smaller diameter than that of the first cell C1 to pass therethrough; and a filtration cylinder 58 for separating, in the storage container 57 and via the filter 60, the liquid L into a first liquid L1 mainly including the first cell C1 and a second liquid L2 mainly including the second cell C2. A measurement target cell discriminated by the filter from the other cells can be easily collected.

The invention discloses a segmentation method for unconventional cells in a pathological section. The method comprises the steps that cells in the pathological section are processed into separate to-be-segmented cell images with a transparent background, and a pixel tag is allocated to each pixel point of each to-be-segmented image; a mapping method is used to randomly distribute the to-be-segmented cell images on a white background, the cells are superposed according to a certain probability to form pseudo-input images, and corresponding full-image pixel tags are acquired and marked as real-value tags; the pseudo-input images and the real-value tags are used as training data to train a Mask-RCNN, so that the Mask-CNN has the abilities of detecting an unconventional cell boundary box and predicting the pixel tags in the box; and a new pathological section not marked is input into the converged Mask-RCNN, the unconventional cells in the non-segmented pathological section are detected, and a final segmentation result is obtained through postprocessing. Through the segmentation method, marking time can be effectively shortened, marking cost can be effectively lowered, a large amount of training data can be generated in a short time, and fitting can be well performed on a large amount of data.

The invention relates to a microfluid cell processing chip comprising a bottom layer and a top layer. A snakelike pipe and a cell operation chamber are disposed in the top layer, and two solution inflow channels are disposed on the inflow-port of the snakelike pipe. A protective agent entrance is disposed on the inlet pipe of one of the inflow channels, and a buffer solution entrance is disposed on the inlet pipe of another inflow channel. A solution outflow channel of the snakelike pipe is connected with the cell operation chamber, and the cell operation chamber is provided with a solution exit, a waste fluid outflow channel and a cell access channel. A row of cylindrical barriers are disposed on each side of the cell operation chamber, and the barriers are used for limiting the cell in the operation chamber, so that the cell can not be washed away by the protective agent. In practical application, operator uses the refitted cell mouth-sucking device to blow or suck the cell in or out the chip cell operation chamber directly. The microfluid cell processing chip and application method thereof can make the concentration of protective agent change continuously when adding or removing the cryoprotectant of animal cell with large volume. The method has direct and simple operation, and has less damage for cell.
