Abstract:
The instant invention involves the use of a combination of preparatory steps in conjunction with mass spectroscopy and time-of-flight detection procedures to maximize the diversity of biopolymers which are verifiable within a particular sample. The cohort of biopolymers verified within such a sample is then viewed with reference to their ability to evidence at least one particular disease state; thereby enabling a diagnostician to gain the ability to characterize either the presence or absence of said at least one disease state relative to recognition of the presence and/or the absence of said biopolymer, predict disease risk assessment, and develop therapeutic avenues against said disease.
Abstract:
An image sensor may have a pixel array and an imaging lens for forming an image on the pixel array. The sensor may also include a pixel readout unit for enabling individual pixel values to be readout. The sensor may further include a pixel selection unit wherein at least one pixel sub-array is selected according to the pixel values readout and the at least one sub-array is used for reading the image.
Abstract:
A method for designing an integrated circuit where the integrated circuit includes a plurality of modules and where each module includes an initiator port and a target port coupled to a distributed routing network. The initiator port is implemented by configuring whether the initiator or the distributed routing network is responsible for ordering responses to requests issued by the initiator port and defining the maximum number of requests that are permitted to be outstanding at the same time. The initiator port is further configured to define whether a delay stage is required in said initiator port. The distributed routing network is defined by the number of routing resources between the initiator and the target, an arbitration method for arbitrating between requests and an association between the routing resources and the targets.
Abstract:
A method of mounting an electronic component having at least one contact extending across a part of its undersurface may include providing a support smaller in area than the undersurface of the component and having a contact pad for connection to the contact. The contact pad may have a first portion extending across an upper surface of the support adjacent one edge and a second portion extending from the edge across a side surface of the support. The method may also include positioning the electronic component and the support with the undersurface of the component adjacent the upper surface of the support. This is done so that the first portion of the contact pad is aligned with and spaced apart from a first portion of the contact, and the second portion of the contact pad is aligned with and disposed inwardly of a second portion of the contact.
Abstract:
A data processing system having shared memory accessible through a transaction-based bus mechanism. A plurality of system components, including a central processor, are coupled to the bus mechanism. The bus mechanism includes a cache coherency transaction within its transaction set. The cache coherency transaction comprises a request issued by one of the system components that is recognized by a cache unit of the central processor as an explicit command to perform a cache coherency operation. The transaction further comprises a response issued by the central processor indicating status of the cache coherency operation.
Abstract:
A ramp generator includes a resistance ladder supplied with a constant current. Switches are closed in sequence by a shift register to provide a stepped ramp output. The constant current is controlled by referencing an on-chip bandgap voltage that is used as an input to a feedback circuit controlling current through a reference resistor ladder.
Abstract:
An image sensor includes pixels which are of the four-transistor, PIN photodiode type. In each pixel, the charge on a photodiode is transferred by a transfer gate to a sensing node. Readout of reset and read voltages is via an amplifier. A gain capacitor is connected in feedback across the amplifier. Read and reset gates are controlled so that the pixel is reset to a virtual ground voltage controlled by the gain capacitor. This is independent of the pixel parasitic capacitance.
Abstract:
Digital data is transmitted in a block-based hyperframe that consists of N frames. Each frame carries multiplexed data from one or more user data channels and a control channel. Control channel information is unequally allocated among the N frames, the amount of information carried in each frame varying according to the frame's position in the hyperframe. All of the user data channels except one carry a predetermined number of transmission units in each frame. The excepted user data channel carries a calculated amount needed to round out the particular frame. Following multiplexing, a block encoder defines the frames and adds error detection or error correction information. The number of frames per hyperframe and the total number of transmission units for the control channel are available to a receiver, which can then demultiplex the hyperframe.
Abstract:
Methods and systems provide an efficient power save mode for multi carrier modems, such as DMT based ADSL and VDSL modems. Fast transitions from power save mode to full operational mode occur, without the overhead of transmitting large quantities of configuration information between the transmitter and receiver. Signal constellation size changes occurring while operating in power save mode to continue to apply once full operational mode is resumed. Multiple power save modes are enabled, each having a different level of power dissipation and crosstalk, both far end crosstalk and near end crosstalk. Power dissipation and crosstalk can thus be graduated on a line, according to a user-requested bit rate.
Abstract:
An image sensor includes an array of digital pixels, a first frame store for storing reference data, and a second frame store for storing image data. The reference and image data are combine to cancel an off-set of the pixels in the array. A re-set and a calibration phase are performed while a shutter is closed to obtain reference data during a calibration phase. A comparator measures an off-set time to gather information on the off-set of the pixels. During or after an exposure phase a conversion time is measured representative of the illumination on the pixel. During the calibration phase the off-set is measured. This digital technique requires a much smaller voltage swing on the pixel, and known techniques and can be performed in a shorter time. This increases the overall frame rate of the image sensor since the time taken for the reset and calibration phases is less than the time taken for the exposure phase.
