Abstract:
Network DNA may be determined for a computer network that taxonomically classifies the computer network. Network DNA may include derived network DNA components and raw network DNA components. Raw network DNA components may be acquired from local or remote sources. Derived network DNA components may be generated according to derived network DNA component specifications. Derived network DNA component specifications may reference raw network DNA components. Network DNA determined for the computer network may include a network species component capable of indicating network species classifications for computer networks. Network species classifications may include enterprise network, home network and public place network. Network species classifications may be determined as a function of network security, network management and network addressing. One or more network DNA stores may be configured to store network DNA for computer networks. Network DNA stores may store network DNA history as well as current network DNA.

Abstract:
As part of a cryptographic protocol, or in addition to it, a computer may participate in a cryptographic key generation protocol. The cryptographic key generation protocol may be such that it generates a set of bits sufficient for a cryptographic key and, also, one or more additional bits. The cryptographic protocol may have one or more parameters, and the parameters of the cryptographic protocol may be varied as a function of the additional bits generated by the cryptographic key generation protocol. The cryptographic protocol may specify a set of one or more cryptographic key sizes. An overkey may be generated that is at least one bit greater than the set of cryptographic key sizes specified by the cryptographic protocol. The parameters of the cryptographic protocol may then be varied as a function of some subset of bits of the overkey. Cryptography-based security may thus be enhanced.

Abstract:
A Universal Serial Bus (USB) flash drive comprising a controller including a USB interface and a nonvolatile computer readable medium interface. The USB flash drive may also comprise a nonvolatile computer readable medium in communication with the nonvolatile computer readable medium interface and storing data and a USB connector in communication with the USB interface. The USB flash drive may also comprise a transmitter for transmitting at least a portion of data from the nonvolatile computer readable medium to an external device external to the USB flash drive. The transmitter may be substantially simultaneously operable with the USB connector, may send a modulated data signal, and/or may send the at least portion data in a compressed format.
Abstract:
A process for secure, safe, and easy provisioning of a wireless device with credentials to connect to a wireless network. A connecting wireless device and an established wireless device both utilize low power transmission at close proximity to exchange wireless connection setting information and/or a password. The connecting wireless device is moved into proximity with the established wireless device and a low power setting is discovered at which the wireless devices may communicate with a sufficiently low error rate. The connecting wireless device is then passed the secret information by the established network device.
Abstract:
The principles of the present invention provides for using directional antennas to increase signal strength and enhance throughput in a wireless network. An antenna device includes an omni-directional antenna and at least one directional antenna. Each directional antenna (e.g., an electronically steered phased array antenna) can have one or more feeds for directing beams to wireless devices. The antenna device utilizes the omni-directional antenna to send and receive control data that facilitates locating wireless devices and determining when a wireless device is to send program data to or receive program data from the antenna device. The antenna device utilizes the directional antenna to send program data to and receive program data from wireless devices. Since the directional antennas use directional beams, the range and barrier penetration of directional antennas is greater than that of the omni-directional antenna.
Abstract:
A wireless device and method provides for adding nodes to a wireless mesh network by adjusting an antenna sensitivity pattern of one or more nodes in the wireless mesh network to exhibit spatial selectivity. The method transmits a query, and if a response is received within a predetermined time period, the wireless device receives the response and adds the responding wireless device to the mesh network. The wireless device can adjust the transmission pattern to enable the antenna sensitivity pattern to cover a predetermined spatial area, and the predetermined time period can be fixed. The wireless devices can adjust the antenna sensitivity pattern in a coordinated manner. A method for supporting data connections between three or more wireless devices includes adjusting the sensitivity pattern of an antenna on a first wireless device, communicating with a second wireless device, and further adjusting the sensitivity pattern of the antenna for more wireless devices.
Abstract:
A detectable pavement warning assembly includes a web having a plurality of projections attached to one another by linear connectors, a planar cover with a series of apertures for receiving the projections therethrough and an adhesive sheet. In use a rigid substrate such as a sidewalk is selected, and a primer is applied. The web, cover and adhesive sheet all pre-assembled are placed on the primed substrate. Next, the warning assembly is heated with an open flame to soften and fuse the pavement warning assembly with the primed substrate. The projections will remain extended sufficiently above the cover to provide a warning to pedestrians that walk thereon, such as when approaching a traffic area or other hazard.
Abstract:
The invention is an apparatus for determining a temperature at which a phase change occurs in a fluid sample, a method for measuring a temperature at which a phase change occurs in a sample and a sample cell. An apparatus for determining a temperature at which a phase change occurs in a fluid sample 60′ in accordance with the invention includes a sample cell (12′)for providing direct collection of the sample from a sample source (74) which is collected and retained at a collecting end thereof by capillary attraction between the collecting end and the sample, the sample cell including a longitudinal passage (78) extending from the collecting end to a far end through which light is transmitted to provide an image of the sample as retained at the collecting end of the passage and with a cross sectional area of the passage being greater at the far end than at the collecting end; a heating and cooling assembly (14), including a temperature sensing device (44), the heating and cooling assembly holding and thermally contacting the sample cell during the determining of the temperature by the temperature measuring device at which the phase change occurs while the sample is positioned in the collecting end; and an illumination system (16) for directing a light beam to the collecting end, through the sample, through the longitudinal passage and out of the far end to permit viewing of the sample from the far end to determine the temperature at which the phase change occurs.
