Abstract: A technique for providing an improved way to update the nodes of a wireless mesh network is described. An upgrade engine executing on a server connected to the wireless mesh network determines a topology of the network, subdivides the network into a plurality of clusters based on the topology of the network, and seeds a small number of nodes within each cluster. The upgrade engine manages the upgrade process, notifying particular nodes within each cluster when to search for an upgrade package (e.g., an image of a new firmware) stored in an adjacent node. The upgrade engine also monitors success and failure of each node and delivers the upgrade package to a node directly when the node fails to download the upgrade package from an adjacent node within the network.

Abstract: An approach for enabling a customer to provision resources of a packetized voice service provider based on one or more customer conditions is described. A provision management platform receives a request for provisioning a domain name service as part of packetized voice service. In response to the request, the provision management platform prompts via a graphical user interface to obtain information for populating a service record of the domain name service. The provision management platform then generates the service record for storage corresponding to a customer account for the packetized voice service.

Abstract: Aspects of the disclosure provide methods for positioning transmitting stations, such as cell towers. Further, aspects of the disclosure provide a database for storing information of the transmitting stations. In addition, aspects of the disclosure provide methods for positioning a moving object having a receiver based on the database of the transmitting stations and wireless signals transmitted by the transmitting stations. The methods increase in-transit location visibility of shipment while reducing GNSS usage, and thus reduce power consumption. The methods allow positioning receiving stations when GNSS signals may not be available, such as due to interference.

Abstract: A handle for a safety razor has an elongated cavity within the handle and a body disposed within the elongated cavity and moveable along the cavity under the influence of gravity between two positions. In a first position the razor has a first center of balance. In the second position the razor has a second center of balance different from the first center of balance. The handle has a damping fluid within the cavity or a resilient member to damp the movement of the body.

Abstract: In a method of forming a semiconductor device on a semiconductor substrate (100), a photoresist layer (102) is deposited on the semiconductor substrate; a window (106) is formed in the photoresist layer (102) by electron beam lithography; a conformal layer (108) is deposited on the photoresist layer (102) and in the window (106); and substantially all of the conformal layer (108) is selectively removed from the photoresist layer (102) and a bottom portion of the window to form dielectric sidewalls (110) in the window (106).

Abstract: A single-step immunoassay method, kit, and reagents for detecting and quantifying contaminant host cell proteins in a recombinant protein sample are described. The method includes the step of adding to immobilized medium comprising a capture reagent including anti-host cell protein antibodies, both the recombinant protein sample and a detection reagent comprising anti-host cell protein antibodies and a detectable moeity. The recombinant protein sample and two reagents are added simultaneously. This single-step format provides greater interaction between the capture antibody, the contaminant host cell proteins that may be present in the recombinant protein sample, and the detection antibody. By providing the opportunity for both antibodies and HCPs to interact at the same time, the one step format allows the formation of the “capture antibody-HCP-detection antibody” complex with all possible HCPs present.

Abstract: Accordingly, this invention relates to an dry etching process for semiconductor wafers. More particularly, the present invention discloses a dry etching process including a halogen etchant (24) and a nitrogen gas (28) that selectively etches a compound semiconductor material (18) faster than the front-side metal layers (16A)(16B). Further, the dry etching process produces a vertical wall profile on compound semiconductor material (18) in both X (38) and Y (40) crystalline directions without undercutting the top of a via-opening.

Abstract: A system to monitor performance of a computing device includes a first bridge to interface with a first set of devices, and a second bridge to interface with a second set of devices. Configuration registers store configuration data associated with the second set of devices, and are accessible through the second bridge. A hub interface allows data to transfer downstream from the first bridge to the second bridge, and allows data to transfer upstream from the second bridge to the first bridge. A controller, external to the first and second bridges, accesses the configuration registers via the second bridge. A logic device allows the second bridge to send data to, and receive data from, the controller.
