Appl. No.:

08/924867

Inventors:

Stephen T. Wong - San Francisco CA
James Yuan-Pin Yu - Sunnyvale CA

Assignee:

Koninklijke Philips Electronics N.V. - Eindhoven

International Classification:

H04L 900

US Classification:

713176, 705 3

Abstract:

A medical image management system including an image archive server for storing image datasets received from a plurality of image acquisition computers and a plurality of display stations for displaying requested image datasets retrieved from the image archive server is provided with an authentication and security system which includes an authentication server for maintaining and storing hashes and timestamps, and for providing hash, timestamp pairs in encrypted form in response to requests from display stations. The image acquisition computers are configured for computing hashes and providing them and image dataset identifiers to the authentication server, receiving timestamps from the authentication server which are then inserted in the image datasets, and storing the image datasets in the image archive server. The display stations are configured for retrieving image dataset, computing hashes from retrieved image datasets, requesting and decrypting hash/timestamp pairs received from the authentication server, and comparing the hashes, and optionally the timestamps, obtained from the authentication server with those computed or extracted from the image datasets received from the image archive server.

Appl. No.:

12/433080

Inventors:

James Yu - San Francisco CA, US
Minh Tran - San Jose CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H03H 2/00
H04B 3/00

US Classification:

333 24R, 375257

Abstract:

A system and method for enabling power applications over a single conductor pair. In one embodiment, data transformers are coupled to a single conductor pair using one or more direct current (DC) blocking elements that preserve an alternating current path. Power is injected onto the single conductor pair after the DC blocking elements and power is extracted from the single conductor pair before the DC blocking elements. Saturation of the data transformers by the injection of power onto the single pair is thereby prevented.

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

G06F 1/26

US Classification:

713300

Abstract:

An active powered device (PD) for the application of power over Ethernet (PoE). In a fixed power budget environment, it is important for the power sourcing equipment (PSE) to accurately determine a power budget for the various powered ports. An active PD can be designed to gather additional information (e.g., current and input voltage) during PD operation and to forward the additional information to the PSE. The PSE can then use the additional information to adjust operational parameters such as a power budget.

Inventors:

James YU - Pleasanton CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

G06F 1/26

US Classification:

713300

Abstract:

Embodiments of power sourcing equipment (PSE) utilizing AC disconnect are provided herein. In one embodiment, a PSE is provided that includes a DC supply configured to provide a DC voltage over a data communications medium, a controller configured to provide an AC disconnect signal over the data communications medium, and a parallel inductor-capacitor (LC) circuit coupled between the DC supply and the data communications medium. The parallel LC circuit is configured to isolate the DC supply from the AC disconnect signal. In another embodiment, a PSE is provided that includes a DC supply configured to provide a DC voltage at an output, an inductor coupled between the output of the DC supply and a data communications medium, and a capacitor coupled between the data communications medium and ground. The inductor and capacitor form a series LC circuit configured to generate an AC disconnect signal.

Abstract:

Embodiments are directed towards mobile application development in a cloud-based architecture. Mobile applications may be designed to communicate with a cloud platform over a network. Mobile application developers may be enabled to submit cloud code to cloud platforms for use by mobile applications. If cloud code is provided to a cloud platform, the cloud platform may perform one or more actions to authenticate the cloud code, such as, ensuring that that the user providing the cloud code is authorized to provide the cloud code. If the cloud code is authenticated the cloud platform may perform one or more actions to validate the cloud code. If validated, the cloud code may be activated for use by mobile applications and/or mobile application developers.Activation of the cloud code may include associating the cloud code with one or more function calls and/or with one or more trigger points.

Abstract:

An online system receives from a third-party application on a client device, an anonymous login request to anonymously log a user of the online system into a third-party system associated with the third-party application. Responsive to receiving the anonymous login request, the online system generates a permissions user interface (UI) that provides an interface component including an option for the user to anonymously log into the third-party system using the user's login information for the online system. The online system provides the permissions UI to the client device, and receives permissions information from the client device. The online system generates an anonymous identifier that allows the user to login to the third-party system. The online system provides the anonymous identifier to the third-party application to allow anonymous login of the user into the third-party system in accordance with the permissions information.
