摘要:
A method of fabricating an array with multiple sets of neighboring features. In the method, for each of multiple sets of neighboring features, at least one set of drops is deposited from a corresponding same pulse jet dispenser onto a substrate so as to form the array with the sets formed from drops deposited by respective different dispensers. Apparatus and computer program products which can execute a method of the invention, are also provided.
摘要:
A motion detection scheme is described which periodically sends a plurality of pulsed ultrasonic signals from a transducer to a particular range cell to receive a series of backscattered signals from the particular range cell. The time interval between any two pulses is greater than a largest dimension of the range cell divided by a slowest velocity of motion at the particular range cell. A temporal variation between the envelopes of the signals is then determined to detect motion at the particular range cell. This scheme may be applied at all points in an image, to produce images that depict regions undergoing motion.

摘要:
A method of fabricating an addressable array of biopolymer probes on a substrate according to a target array pattern using a deposition apparatus, and a deposition apparatus which can execute the method and computer program products for the apparatus. The deposition apparatus which, when operated according to a target drive pattern based on nominal operating parameters of the apparatus, provides the probes on the substrate in the target array pattern. The method includes examining at least one operating parameter for an error from a nominal value which error will result in use of the target drive pattern producing a discrepancy between the target array pattern and an actual array pattern deposited. When an error is detected deriving, based on the error, a corrected drive pattern different from the target drive pattern such that use of the corrected drive pattern results in a reduced discrepancy between the target and actual array patterns.
摘要:
A drop deposition apparatus, and a method and computer program products using the drop deposition apparatus, for fabricating at least one addressable array of biopolymers on a substrate. The drop deposition apparatus has a drop dispenser unit and a sensing element. The method comprises includes for each of multiple addresses, dispensing droplets carrying the biopolymers or biopolymer precursors from a drop dispenser unit onto the sensing element, and onto the substrate so as to fabricate the array. Electrical signals resulting from dispensed droplets striking the sensing element are detected. A performance characteristic of the deposition apparatus is evaluated based on the detected signals.
摘要:
A method, apparatus and computer program product, for fabricating an array of biopolymers on a substrate. The method uses a biopolymer or biomonomer fluid and a drop dispenser having a chamber into which the fluid is loaded and an orifice communicating with the chamber from which the fluid is dispensed. The method includes, when the chamber is loaded, applying a prime pressure to the fluid which varies over a range sufficient to move fluid within the drop dispenser but insufficient to cause fluid to be dispensed from the orifice. Drops are dispensed from the dispenser to the substrate so as to form the array.
