摘要:
An integrated circuit has a semiconductor substrate and an interconnect layer that mechanically relatively weak and susceptible to cracks and delamination. In the formation of the integrated circuit from a semiconductor wafer, a cut is made through the interconnect layer to form an edge of the interconnect layer. This cut may continue completely through the wafer thickness or stop short of doing so. In either case, after cutting through the interconnect layer, a reconditioning layer is formed on the edge of the interconnect layer. This reconditioning layer seals the existing cracks and delaminations and inhibits the further delamination or cracking of the interconnect layer. The sealing layer may be formed, for example, before the cut through the wafer, after the cut through the wafer but before any packaging, or after performing wirebonding between the interconnect layer and an integrated circuit package.

A method transmits packets over a single channel in a wireless communication network that includes multiple nodes. Access to the channel is gained in a transmitting node. Then, a block of packets is transmitted to a receiving node via the channel. The transmitting node receives only a single acknowledgement packet from the receiving node in response to transmitting the block of packets.

An optical detection device is provided. The detection device includes a light source emitting light rays, a focusing lens, and a sample testing member. The focusing lens refracts the light rays emitting from the light source to a pre-defined area on the sample testing member and focuses light rays diffusely reflected by the sample testing member. The detection device further includes an aperture diaphragm having an aperture. The aperture is configured to allow the focused reflected light rays to pass through. The detection device further includes a photodetector configured to receive the focused reflected rays passing through the aperture.

A preassembled medicine mixer comprises a rotary sleeve (4), a guide sleeve I (3), a guide sleeve II (6), a guide part, a dosing barrel (1), and a dosing double needle (2). The guide sleeve I (3) extends into the guide sleeve II (6) and is connected to the rotary sleeve (4). A guide groove (8) is provided on the side wall of the guide sleeve I (3), and two ends of the guide groove (8) are extended by a distance towards opposite directions. A guide spiral groove (7) is provided on an inner wall of the guide sleeve II (6). The guide part is disposed in the guide sleeve I (3) and has a guide block (9) at the outer side thereof. The guide block (9) penetrates through the guide groove (8) and extends into the guide spiral groove (7). In use, the rotary sleeve (4) is rotated to drive the guide part to rapidly move downwards and push a medicine container (17); an upper needle tip of the dosing double needle (2) pierces a sealing plug on the medicine container (17), and a lower needle tip pierces a diaphragm (23) in an interface (22), so that the medicine container (17) is instantly communicated with an infusion container (14), thereby implementing sterile closeness during the entire process of transportation, storage, butt joint, medicine mixing, and infusion.

A computer-implemented method may include receiving, at the base station, an identification and request for transmission access from a wireless computing device, determining a level of efficiency for data communications between the base station and the wireless computing device, selecting a descriptor for the level of efficiency, from among a plurality of predetermined descriptors that identify discrete efficiency classifications across a range of efficiencies, determining a share of bandwidth for communication between the base station and the wireless computing device based on the selected descriptor, and communicating electronically with the wireless computing device using the selected share of bandwidth. A higher share of bandwidth may be selected for a wireless computing device having a higher determined level of efficiency.
摘要:
A computer-implemented method may include receiving at a wireless device one or more beacon packets sent by a communication base station, determining a delay period at the wireless device, wherein the delay period is determined so that a delay for the wireless device is different than a delay for another wireless device, sending a first association request from the wireless device after waiting for the delay period, and establishing communication with the base station if an association response is received from the base station within a determined time period. The first association request may include information identifying the wireless device and an association code.

The invention discloses an optimized DNA sequence of recombinant human bone morphogenetic protein-2 (rhBMP-2) based on the Escherichia coli expression system and a method for the preparation of the rhBMP-2. Specifically, the invention provides the optimal DNA sequences suitable for Escherichia coli expression system, the methods for efficient preparation of the rhBMP-2, and the related construction of the recombinant bacteria, the expression and purification technologies. Compared with the traditional hBMP-2 gene without optimizing, the rhBMP-2 expression level of the optimized gene in Escherichia coli is increased by 50%. Additionally, this invention also provides a method for preparation long chain rhBMP-2 with enhanced renaturation efficiency and yield of purification.
摘要:
A media access controller (MAC) for wireless mesh networks comprises a quality-of-service (QoS) manager to monitor consumed bandwidth of a current application flow and to compare the consumed bandwidth with a contracted bandwidth for the current application flow. The MAC also comprises a contention manager to coordinate access to a wireless communication channel for communications with other nodes of the wireless mesh network. The QoS manager instructs the contention manager to employ signaling to request additional resources for the current application flow after the consumed bandwidth is significantly less than the contracted bandwidth.
