Abstract:

A method for mapping a DICOM document into a UML document is disclosed and claimed by this invention. The method includes mapping each DICOM Information Entity in the DICOM document into a corresponding UML class in the UML document, mapping each DICOM IOD Module in the DICOM document into a corresponding UML class in the UML document, mapping each DICOM Macro in the DICOM document into a corresponding UML class in the UML document, and mapping each DICOM Attribute in the DICOM document into a corresponding UML attribute in the UML document. It also includes a UML profile for DICOM information model which guides the UML modeling for all the DICOM IODs. It can also guide the genertion of XML schemas and DTDs from UML models based on this profile.

International Classification:

H01R 13/73

US Classification:

439545, 439564

Abstract:

In an embodiment, an apparatus includes a housing and a cover. The housing can include a surface to receive a terminal block to transmit power to an electrical component. A shroud to be inserted within the electrical component can extend away from the housing surface. The cover can have an end for hingedly attaching to the housing. The cover is pivotable relative to the housing between a closed position and an open position. In the closed position, the cover and the housing together form an enclosure for the terminal block.

International Classification:

H04W 76/15
H01Q 1/22
H04B 7/0413

Abstract:

Technologies directed to a wireless network device with a single hardware architecture that supports multiple devices roles through software configuration are described. One wireless network device includes a housing with an RF connector and a circuit board with a first radio coupled to an internal antenna and a second radio coupled to an external antenna via the RF connector. The second antenna is mounted on an exterior surface of the building and coupled to the RF connector via an RF cable. The wireless network device receives a command identifying a device role for the wireless network device and configures itself according to the device role using device setting.

International Classification:

G06F 1/26
G06F 13/40

Abstract:

In various embodiments, rail decoupling circuits that are powered by an always on voltage rail allow a core voltage rail to power up independently of an I/O voltage rail without jeopardizing I/O pad circuits that are powered by the I/O voltage rail. In an embodiment, when the always on voltage rail is powered-up and a chip reset signal is asserted, the rail decoupling circuits drive control inputs of the I/O pad circuits based on default values. When the chip reset signal is de-asserted, the rail decoupling circuits drive the control inputs of the I/O pad circuits based on signals received from circuits powered by the core voltage rail. Because the rail decoupling circuits maintain control of the I/O pad circuits until the chip-reset is de-asserted, the core voltage rail can power up at any time before the chip-reset signal is de-asserted irrespective of when the I/O voltage rail powers up.

International Classification:

H01Q 19/00
H01Q 9/04

Abstract:

Technologies for wireless network devices with surface-link antenna systems mounted on exterior surfaces of buildings are described. One wireless network device includes a housing with a circuit board and a first antenna port. A processor, a first antenna, a first wireless local area network (WLAN) radio, and a second WLAN radio are disposed on the circuit board. The first WLAN radio communicates with a radio of a client device using the first antenna over a first line-of-sight (LOS) or non-LOS wireless link (e.g., 2.4 GHz) inside the building. The second WLAN radio communicates with a radio of a second wireless network device using the second antenna over a second LOS wireless link (e.g., 5 GHz) that is external to the building. The first antenna is located inside the building and the second antenna is located along an exterior surface of the building.

International Classification:

H04B 1/00
H04M 1/02

Abstract:

Network hardware devices organized in a Wireless mesh network (WMN) in which the network hardware devices cooperate in distribution of content files to client consumption devices in an environment of limited connectivity to broadband Internet infrastructure are described. One mesh network device includes a micro controller, RF radios, and antenna switching circuitry. The antenna switching circuitry, in response to the control signals from a micro controller, selectively couples individual ones of a first set of antennas to individual channels of the set of RF radios to communicate content data with client consumption devices and selectively couples individual ones of a second set of antennas to other individual channels of the set of RF radios to communicate content data with other mesh network devices in a WMN.
