摘要： An image sensor having an image acquisition mode and an ambient light sensing mode includes a pixel array having pixel cells organized into rows and columns for capturing image data and ambient light data. Readout circuitry is coupled via column bit lines to the pixels cells to read out the image data along the column bit lines. An ambient light detection (“ALD”) unit is selectively coupled to the pixel array to readout the ambient light data and to generate an ambient light signal based on ambient light incident upon the pixel array. Control circuitry is coupled to the pixel array to control time sharing of the pixels cells between the readout circuitry during image acquisition and the ALD unit during ambient light sensing.

摘要： An image sensor includes a device wafer including a pixel array for capturing image data bonded to a carrier wafer. Signal lines are disposed adjacent to a side of the carrier wafer opposite the device wafer and a metal noise shielding layer is disposed beneath the pixel array within at least one of the device wafer or the carrier wafer to shield the pixel array from noise emanating from the signal lines. A through-silicon-via (“TSV”) extends through the carrier wafer and the metal noise shielding layer and extends into the device wafer to couple to circuitry within the device wafer. Further noising shielding may be provided by highly doping the carrier wafer and/or overlaying the bottom side of the carrier wafer with a low-K dielectric material.

摘要： A method for determining the concentration of asphaltenes in a solution is described. A model is first established for estimating the concentration of asphaltenes in a solution based on multiple samples of solutions of asphaltenes in the solvent in which the concentrations are known. The multiple samples have varying concentrations of asphaltenes. The diffusivity and relaxation time are measured for each sample using two-dimensional NMR. The ratio of diffusivity to relaxation time for each sample is then calculated. A linear equation is determined to fit the relationship between the ratio of diffusivity to relaxation time and the asphaltene concentration by weight for the multiple samples, thus creating the model. For a given solution sample for which the concentration of asphaltenes is desired to be determined, diffusivity and relaxation time are determined using two-dimensional NMR, and the ratio of diffusivity to relaxation time is calculated. This ratio is then used with the model, so that the linear equation can be solved for the asphaltene concentration in the given solution sample.

摘要： A CMOS image sensor that is capable of both voltage- and current-mode operations selects the mode based on the position of mode switches. Each pixel on the imager has a single transistor acting as either source follower for voltage readout, or transconductor for current readout. The two modes share the same readout lines, but have their own correlated double sampling (CDS) units for noise suppression. A current-mode readout technique using a velocity-saturated short-channel transistor may be used to achieve high linearity. An image array may be formed as a mixture of 3 types of pixels with identical photodiodes and access switches. The readout transistors are optimally sized for their designated mode of operation. Alternatively, two readout transistors are provided per pixel, each individually optimized for the desired mode of operation.

摘要： A method and device for charging a metal hydride hydrogen store (13) is described. It comprises generating gaseous hydrogen in an electrolyser (1), transporting the gaseous hydrogen to the metal hydride store and feeding the metal hydride store with the hydrogen. For having the hydrogen free of water contamination, the gaseous hydrogen is first transported under a first pressure of at least 1 MPa which pressure is then reduced by a pressure adjusting means (11) to a second, designated pressure lower to the first pressure, the second pressure being the feeding pressure to the metal hydride store.

摘要： An online payment system uses an electronic check system to make a payment to a merchant on behalf of an online customer. The electronic check system receives a check application request of the customer, creates an electronic check number and a password for the check, outputs the check information to the customer, and stores the check information in the electronic check system. When a merchant system receives an online payment request of the customer, it sends the request to the electronic check system, which then parses out a payment electronic check number and a payment check password from the payment request, verifies the parsed information with the stored check the information, and makes a payment to the merchant. The electronic check system is centralized and shared by multiple merchants. A payment only needs access to the electronic check system, without requiring participation of multiple receipt-acquiring systems of individual merchants.

摘要： A system for reliable multicast distribution includes a primary content engine and a backup content engine sender. The primary content engine sender sends out a multicast message of content to selected content engine receivers. The sender waits for negative acknowledgments from the selected content engine receivers declaring that content was not received. If a negative acknowledgment is received, the sender resends the multicast message a predetermined number of times. If the content is still not received after the number of multicast passes is exhausted, the sender sends out unicast messages to those receivers still requesting content. If the primary sender does not respond to a negative acknowledgment, the receiver sends a second negative acknowledgment to the backup multicast sender. The backup responds with the data requested in the negative acknowledgment and so is able to begin data distribution at the point where the primary sender left off without maintaining synchronicity with the primary sender.
