There is provided a solid-state image pickup device including ADCs that can be arranged in a limited space. The potential of a pixel signal outputted through a vertical readout line is held at a node. A plurality of capacitors are capacitively coupled to the node at which the pixel signal is held. The potential of the node is decreased in a stepwise manner by sequentially switching the voltages of the counter electrodes of the capacitors by the control of transistors.

Following this, the conversion of the lower bits of the digital value is started. Therefore, it is possible to simplify the configuration of each ADC and arrange each ADC in a limited space.

As a result, dark current only for one line occurs in each pixel, and the dark current for one line itself can be reduced markedly. Consequently, defective pixels due to non-selection hot carrier white points can be virtually eliminated.

The first device plays the stream of media (e.g., for a user) and generates an analog signal based on the stream of media. A second device (e.g., a mobile device of the user) is configured to receive the analog signal and generate a representation of the analog signal. The second device provides the representation of the analog signal to the server machine, which may compare the representation of the stream of media to the representation of the analog signal. Based on the comparison, the server machine may provide an identifier of the media source to the second device.

The server may determine eligibility for IUT with group synchronization based on the request. The server may send a message to the initial UE that IUT with group synchronization is not allowed on a condition that IUT with group synchronization is not allowed.

The media sessions may include a first media session and second media session. The media stream may be played by at least two UEs that are geographically separated after the transfer.
Sustaining session connections
In an embodiment, techniques for sustaining session connections are provided. The techniques send heartbeat messages when not sending a message may cause the session connection to close because of a timeout condition. Heartbeat messages are valid transport layer messages that will be ignored by protocols at higher levels of a data communications stack. As an example, the techniques may send a TCP message containing only a carriage return and line feed (“CRLF”) in its payload. Because the TCP layer considers a message containing only a CRLF to be a valid TCP message, intermediary computing devices such as proxy servers may not interpret heartbeat messages as “keep alive” messages, and may sustain session connections.

The invention relates to a method of changing allocation of Serving-Call Session Control Functions (S-CSCFs) to a user of an IMS network. The user is being provided with services via a first S-CSCF allocated to the user. The method includes implementing a re-allocation instruction at the first S-CSCF. The reallocation instruction includes criteria for de-allocation of the user from the first S-CSCF. The S-CSCF determines if the criteria are met; and if the criteria are met, de-allocates the user.
Extending organizational boundaries throughout a cloud architecture
An information sharing paradigm for a cloud computing solution enables flexible organizational boundaries with respect to cloud resources. Cloud service customers manage their own organization boundary but can extend that boundary selectively by associating cloud resources they own with sets of domain names that may be associated with requests for cloud resources that the organization may be willing to share with other organizations that are using the cloud environment, and by ensuring that any such requests for resources that are shared in this manner are associated with one or more message handling policies that have been defined by (or otherwise associated with) the resource-owning organization. Cloud resources owned by an organization (even those marked as “internal only”) may be selectively shared with one or more other organizations using the cloud environment depending on the domain names associated with the requests. Message handling policies are enforced with respect to shared resources.

The policy engine identifies commands corresponding to the communications packets and directs the communications packets to appropriate rules engines corresponding to such commands in order to execute rules to comply with an organization's policies. Upon completion of execution of the rules, the communications packets are forwarded to the cloud computing environment if they comply with the policies.
