Abstract: A syringe includes a barrel, a plunger, and a sealing member creating a seal between the plunger and the barrel. The barrel includes a first portion with a first inner diameter and a second portion with a second inner diameter that is larger than the first inner diameter. The sealing member engages the first portion of the barrel to give rise to a first contact pressure when the barrel is filled with product. The first contact pressure is sufficient to maintain a gas-tight seal over the expected temperature ranges ?25° C. to 40° C. A first force is applied to the plunger to overcome the first contact pressure and move the plunger out of the first portion and into the second portion to dispense product. The sealing member engages the second portion of the barrel to give rise to a second contact pressure that is lower than the first contact pressure.

Abstract: The present teaching relates to monitoring data in a plurality of data sources of heterogeneous types. In one example, a request is received for monitoring data in the data sources of heterogeneous types. One or more metrics are determined based on the request. The request is converted into one or more queries based on the one or more metrics. Each of the one or more queries is directed to at least one of the data sources of heterogeneous types. A monitoring task is created for monitoring the data in the data sources based on the one or more queries in response to the request.

Abstract: A system and method for scalable video coding that includes base layer having lower resolution encoding, enhanced layer having higher resolution encoding and the data transferring between two layers. The system and method provides several methods to reduce bandwidth of inter-layer transfers while at the same time reducing memory requirements. Due to less memory access, the system clock frequency can be lowered so that system power consumption is lowered as well. The system avoids having prediction data from base layer to enhanced layer to be up-sampled for matching resolution in the enhanced layer as transferring up-sampled data can impose a big burden on memory bandwidth.

Abstract: A system and method for providing video compression that includes encoding using an encoding engine a YUV stream wherein Y, U and V color values are encoded in parallel and patching together the Y, U and V color streams to form a compressed YUV output stream. The encoding engine further includes encoding each color value of the YUV stream in parallel using parallel encoding engines and a control engine for controlling operation all of the encoding engines in parallel. The YUV stream has an average bits per pixel value that varies from a first value to a second value that is double the first value. The encoding engine includes encoding the YUV stream in generally the same amount of time regardless of the average bits per pixel value.

Abstract: A syringe containing a high water content product and for use in a drug infusion system is provided. The syringe includes a plunger carrying front and rear o-rings made of a diene rubber compound such as chlorobutyl rubber or bromobutyl rubber to impart very low gas permeability characteristics to the o-rings. The plunger may be molded as a single part or in two parts. If molded as one part with radially-engaging mold portions, the seal glands in the plunger may include parting lines from the mold. If molded as two parts with axially-engaging mold portions, the front seal gland may include a sealing surface and under cut that has no parting line. The o-rings may be surface treated with a lubricant to improve sealing where the molding process gives rise to parting lines in the seal glands.

Abstract: A method and system are described for low-latency video. In the method a frame, selected from a group of frames, is divided into P-regions and an I-region based on an assigned refresh pattern in a refresh loop. An I-region bit budget and a P-region bit budget are determined. Quantization parameters are determined using the I-region bit budget and the P-region bit budget. Macroblocks of the selected frame are encoded based on the quantization parameters. The I-complexity and P-complexity are updated and a new frame bit budget is determined. The dividing, determining of the I-region bit budget, determining of the P-region bit budget, determining of quantization parameters and encoding are repeated for each remaining frame in the group of frames.
