摘要:
The present invention provides highly efficient system level EMI filtering in a dual feed Power Distribution Unit (PDU) using custom designed magnetic components that are uniquely designed to provide excellent performance under various load conditions. The PDU of the present invention includes filters for providing the necessary EMI filtering at all frequencies in the range between 200 Hz and 200 MHz under all load conditions including a single feed failure. Additionally, the present invention provides mechanisms for cooling EMI components using a combination of natural convection and conduction techniques at the board level to ensure no loss of EMI filtering performance. The present invention also includes blank panels made of formed Aluminum alloy sheet metal pieces or the like to direct air flow to components on printed wiring boards (PWB's) using air director plates.

The present invention provides a system and method for multi-rate, high-sensitivity CDR, including a variable/adjustable decision threshold, RF input clock recovery, and OE conversion feature. The system includes an optical input connector, CDR circuit, decision threshold circuit, internal power supply, OE converter, external electrical output, and multiple clock outputs. The system is assembled in a single, stand-alone unit. The system includes an OC-192 data output, and OC-192 (9.953-10.709 GHz) and ¼ OC-48 (2.488-2.677 GHz) clock outputs. The decision threshold level is adjustable and optimized by a system user. The system is also used in combination with a digital communications analyzer. A recovered clock of the CDR circuit provides trigger for the DCA. The system includes an electrical input connector. Optionally, the system triggers directly from an RF electrical input in substitution of an optical input. The system is also used to convert an optical signal to an electrical signal, bypassing the CDR circuit.

Embodiments of the systems, devices, and methods described herein generally facilitate transmission and reception of activation data for use in activating a mobile device to operate with a server. In accordance with one example embodiment, an activation barcode is received from a server by reading an image comprising the activation barcode via a computing device, wherein the image is displayed on a display associated with the computing device, and wherein the activation barcode encodes activation data comprising an activation password. The activation barcode is decoded at the mobile device to obtain the activation password, and an authentication is performed using the activation password after a device activation request is transmitted to the server, wherein the mobile device is activated to operate with the server if the authentication is successful.

There is disclosed a user interface for selecting a photo tag. In an embodiment, the user interface embodies a method of selecting a photo tag for a tagged photo, comprising: providing a tag entry field for entering a photo tag; in dependence upon a string entered by a user, displaying in a matching tag list any tags from one or more selected tag sources matching the entered string. The method may further comprise displaying a tag type for each tag appearing in the matching tag list. The method may further comprise allowing user selection of a tag in the matching tag list to complete the tag entry field.
摘要:
A first device with a changing identity establishes a secure connection with a second device in a network by acting as its own certificate authority. The first device issues itself a self-signed root certificate that binds an identity of the first device to a long-term public key of the first device. The root certificate is digitally signed using a long-term private key, where the long-term public key and the long-term private key form a public/private key pair. The first device provides its root certificate to the second device in any trusted manner. The first device can then create a certificate for one or more short-term identities acquired by the first device and sign the newly-created certificate using the long-term private key. The first device can authenticate itself to the second device by sending the newly-created certificate to the second device.
摘要:
A system and method for processing messages being composed by a user of a computing device (e.g. a mobile device). Embodiments are described in which the performance of certain tasks is initiated before a direction is received from a user to send a message being composed by the user. This may involve, for example, “pre-fetching” security-related data that will be required in order to send a message that is in the process of being composed by the user securely. Such data may include security policy data, certificate data, and/or certificate status data, for example.
摘要:
A system and method for determining a security encoding to be applied to a message being sent by a user of a computing device. In one broad aspect, the device comprises a processor configured to: determine whether a general message encoding configuration setting indicates that when a security encoding is to be applied to a message then the security encoding is to be established by a policy engine; if the general message encoding configuration setting so indicates, query the policy engine for the security encoding to be applied to the message; otherwise, determine the security encoding to be applied to the message in accordance with a user-selected security encoding; and apply the determined security encoding to the message prior to transmission of the message to at least one recipient.
摘要:
A method for preventing a recipient of an electronically transmitted message from taking at least one action in relation to the message is disclosed. The message has at least two parts with one of the parts having a higher level of security than the other part. The method includes the step of extracting information from the message. The information indicates that the higher level security part is not permitted to have the action taken on it while the other part is so permitted. The method also includes the step of preventing the higher level security part from having the action taken on it in reaction to said recipient making an offending request.
