20120059932 | APPLYING HOME NETWORK TECHNOLOGIES TO A WIDE AREA NETWORK - In a first embodiment of the present invention, a method for allowing a device on a home network to access a service outside the home network is provided, the method comprising: receiving, at a server outside the home network, a registration message from the service; storing details about the service in a storage accessible by the server, wherein the details include an address for the service; receiving, at the server, a request to locate a service, wherein the request is received from the home network; locating details about a matching service stored in the storage, wherein the matching service meets criteria specified in the request from the home network; and providing the details about the matching service to the home network, enabling the device to directly contact the matching service using the address specified in the details about the matching service. | 03-08-2012 |
20120317162 | COMMUNICATION AND EXCHANGE OF GROUP-RELATED INFORMATION USING A CENTRAL SERVER - The present invention provides a service for sharing, managing, and storing group-related information using existing technology relating to mobile devices, TVs, server computers, and distributed networks. Users in a defined group, such a family, can use devices, such as smart phones or tablets, to get updates from other users or to send information about themselves. The information can be displayed on authorized devices, some of which are generally used to display information, such as TVs. The content type of the communication is determined. The communication is stored in a database on the central server if the communication is a broadcast message or an event message. If the communication is a query message, the central sever responds to the message. If it is an update message, the database in the central server is updated. The group information is displayed in real-time on one or more devices and is combined in one place. | 12-13-2012 |
20150070544 | OVERSAMPLED IMAGE SENSOR WITH CONDITIONAL PIXEL READOUT - In a pixel array within an integrated-circuit image sensor, each of a plurality of pixels is evaluated to determine whether charge integrated within the pixel in response to incident light exceeds a first threshold. N-bit digital samples corresponding to the charge integrated within at least a subset of the plurality of pixels are generated, and then applied to a lookup table to retrieve respective M-bit digital values (M being less than N), wherein a stepwise range of charge integration levels represented by possible states of the M-bit digital values extends upward from a starting charge integration level that is determined based on the first threshold. | 03-12-2015 |
20150201142 | Image sensor with threshold-based output encoding - In a pixel array within an integrated-circuit image sensor, each of a plurality of pixels is evaluated to determine whether charge integrated within the pixel in response to incident light exceeds a first threshold. N-bit digital samples corresponding to the charge integrated within at least a subset of the plurality of pixels are generated, and then applied to a lookup table to retrieve respective M-bit digital values (M being less than N), wherein a stepwise range of charge integration levels represented by possible states of the M-bit digital values extends upward from a starting charge integration level that is determined based on the first threshold. | 07-16-2015 |
20150229859 | FEEDTHROUGH-COMPENSATED IMAGE SENSOR - A control pulse is generated a first control signal line coupled to a transfer gate of a pixel to enable photocharge accumulated within a photosensitive element of the pixel to be transferred to a floating diffusion node, the first control signal line having a capacitive coupling to the floating diffusion node. A feedthrough compensation pulse is generated on a second signal line of the pixel array that also has a capacitive coupling to the floating diffusion node. The feedthrough compensation pulse is generated with a pulse polarity opposite the pulse polarity of the control pulse and is timed to coincide with the control pulse such that capacitive feedthrough of the control pulse to the floating diffusion node is reduced. | 08-13-2015 |
20150373290 | Image Sensor Architecture with Power Saving Readout - Pixels within an image sensor pixel array are sampled by corresponding conditional read circuitry. A zero pixel value is outputted for each pixel associated with a sample less than a conversion threshold, and a saturated pixel value is outputted for each pixel associated with a sample greater than or equal to a saturation threshold. Samples greater than or equal to the conversion threshold and less than the saturation threshold are converted by an ADC, and a converted pixel value is output for each associated above threshold pixel. The ADC (along with any corresponding amplifiers) are powered on for a variable period depending on the number of pixels needing conversion during the conversion of such samples during a read period, and are powered off for the remainder of the read period. | 12-24-2015 |
