An automatic spin coating system includes a dispensing assembly and a base assembly. The dispensing assembly comprises a dispensing device that contains a coating material, a pulley assembly, a drive gear, and a smooth wheel. The base assembly includes a coating plate for receiving the coating material, a chuck plate for securing the coating plate, a stepper pin capable of engaging the drive gear of the dispensing assembly, and an electric motor for spinning the chuck plate. The dispensing device further comprises a vessel assembly to provide immobilization of the dispensing device, and a tubing assembly to control the flow of the coating material. The dispensing device is connected to the pulley assembly, which in turn is connected to the drive gear and the smooth wheel. When the chuck plate spins, the stepper pin revolves and touches the drive gear so as to rotate the pulley assembly, and meanwhile, the coating material is dispensed and coated on the coating plate in different circles without overlap between circles. In one embodiment, the stepper pin has a gear with different sizes of teeth that allow different degrees of movements of the dispensing device. The coating material is then dispensed from a first circle to a second circle.

In general, techniques are described for steering data traffic for a subscriber session from a network interface of a wireless access gateway to an anchoring one of a plurality of forwarding units of the wireless access gateway using a layer 2 (L2) address of the data traffic. For example, a wireless access gateway for a wireless local area network (WLAN) access network is described as having a decentralized data plane that includes multiple forwarding units for implementing subscriber sessions. Each forwarding unit may present a network interface for sending and receiving network packets and includes packet processing capabilities to enable subscriber data packet processing to perform the functionality of the wireless access gateway. The techniques enable steering data traffic for a given subscriber session to a particular one of the forwarding units of the wireless access gateway using an L2 address of the data traffic.

Internal packet steering within a wireless access gateway

In general, techniques are described for aggregating, within a network device, internal forwarding routes for multiple control protocols and allocating next hops for the routes among individual service units of a decentralized control plane for the network device. The techniques may also include aggregating internal forwarding routes for data protocols and allocating next hops for the routes among individual forwarding units of a decentralized data plane for the network device. In one example, a mobile gateway includes a plurality of subscriber management service units that present a uniform interface to nodes within a mobile service provider network. An allocation manager apportions a control protocol session identifier namespace into a plurality of contiguous, non-overlapping protocol session identifier ranges and allocates the ranges among the service units. The service units execute the control protocol by utilizing respective allocated ranges, which the aggregate internal forwarding routes use to identify the associated service units.

Mobile gateway having reduced forwarding state for anchoring mobile subscribers

In general, a mobile virtual private network (VPN) is described in which service provider networks cooperate to dynamically extend a virtual routing area of a home service provider network to the edge of a visited service provider network and thereby enable IP address continuity for a roaming wireless device. In one example, a home service provider network allocates an IP address to a wireless device and establishes a mobile VPN. The home service provider network dynamically provisions a visited service provider network with the mobile VPN, when the wireless device attaches to an access network served by the visited service provider network, to enable the wireless device to exchange network traffic with the visited service provider network using the IP address allocated by the home service provider network.

Virtual private networking with mobile communication continuity

Techniques are described for selecting an alternate path for end-to-end service data traffic that traverses multi-homed routers that provide the service to customer networks. For example, as described herein, a router that is a member of a first multi-homing set connected to a layer two (L2) network with one of a plurality of first access links. The router advertises a status of one of the first access links to a second multi-homing set connected to the first multi-homing set with one or more core links. A core link database stores advertised status information for access links of the first and second multi-homing set. Upon a link failure, a path selector selects a core link to transport service data traffic and directs a switch module to switch to active a status a first access links that connects to a router in the first multi-homing set connected to the selected core link.

This disclosure describes a portable device that conveniently applies cancer patient blood sample into a test strip to determine the level of the patient's metastatic circulating tumor cells. Proper use of this device provides end users with the diagnostic and prognostic information of the cancer patient, and any effect of applied therapies. The device can also be used to screen effective drugs for any known metastatic phenotype disruption.

Targeted cell separation and enumeration device and the use thereof

In general, the invention is directed to techniques for breaking out mobile data traffic from a mobile service provider network to a packet data network. For example, as described herein, a breakout gateway device (BGW) receives a first service request and data traffic for a data session associated with the requested service from a mobile device in a radio access network, wherein the first service request is addressed to a serving node of a mobile core network of the mobile service provider network, and wherein the data traffic is destined for the PDN. A control packet analysis module forwards the first service request from the breakout gateway device to the serving node. A breakout module of the BGW bypasses the serving node by sending the data traffic from the breakout gateway device to the PDN on a data path from the radio access network to the PDN.

Breakout gateway for mobile data traffic

A network system includes a provider backbone bridged network (PBBN) and a multi-homed provider bridge network (PBN) having a plurality of L2 switches that operate as backboned edge bridges (BEBs) to bridges L2 packets between the PBN and the PBBN. A first one of the L2 switches is configured to bridge L2 packets from a first backbone VLAN (B-VLAN) to the PBN when a physical link of the multi-homed PBN is operational. The L2 switch is further configured to shunt the L2 packets from the first backbone VLAN to a second one of the L2 switches operating as a secondary BEB of the multi-homed PBN via a second B-VLAN when the physical link is non-operational.

Avoiding data loss in a multi-homed layer two bridging network

Methods, apparatus, and products are disclosed for forwarding frames in a computer network using shortest path bridging ('SPB'). The network includes multiple bridges, and each edge bridge is assigned a unique service virtual local area network ('VLAN') identifier. One of the bridges receives a frame for transmission to a destination node. The received frame includes a service VLAN identifier for the ingress bridge through which the frame entered the network and a customer VLAN identifier. The one bridge identifies an SPB forwarding tree in dependence upon the service VLAN identifier. The SPB forwarding tree specifies a shortest route in the network from the ingress bridge through the one bridge to the other bridges in the network. The one bridge then forwards the received frame to the egress bridge without MAC-in-MAC encapsulation in dependence upon the SPB forwarding tree and the customer VLAN identifier.
