Abstract: The invention provides compact haptic and augmented virtual reality system that produces an augmented reality environment. The system is equipped with software and devices that provide users with stereoscopic visualization and force feedback simultaneously in real time. High resolution, high pixel density, head and hand tracking ability are provided. Well-matched haptics and graphics volumes are realized. Systems of the invention are compact, making use of a standard personal display device, e.g., a computer monitor, as the display driver. Systems of the invention may therefore be inexpensive compared to many conventional virtual reality systems.

Abstract: A process for constructing an artificial coding sequence is provided. The process comprises providing an enzyme adapted to ligate DNA duplexes containing selected codons into multimers that preserve the reading frame of those codons in a reaction facilitated by the presence of a condensing agent, such as polyethylene glycol. These open reading frames may be useful for expressing proteins with a restricted amino acid content.

Abstract: This invention addresses how an end user can create an electroluminescent device (1, 31) using basic components obtained by the end user as retail items. The layers or subassemblies (15, 17) are created first. Then the layers are assembled to form a completed device customized as selected by the end user. The subassemblies may be created layer-by-layer by thermal inkjet. Elements used typically will be made by manufacturers and sold commercially separately. This encompasses the printing of conductive patterns for electroluminescence on paper. In one aspect a display has a main body that may be permanent and useful indefinitely, while a part carrying the conductive pattern defining the display is readily removed and is replaced by another such part on which a new conductive pattern is printed. For tight contact with the main body, the display provides releasable pressure. Air pockets are minimized with a thin layer of highly viscous dielectric liquid.

Abstract: A medical diagnostic method using systolic and diastolic blood pressures, and pulse frequency of a patient is provided to compute a normalized diastolic distensibility value and a normalized peripheral resistance value, and to automatically compute the product of the normalized diastolic distensibility value and the normalized peripheral resistance value to generate a first product value. The first product value is compared to a stored distribution of normalized diastolic distensibility and a normalized peripheral resistance values for comparable individuals to determine if the first product value is equivalent to a value determined to indicate an abnormal condition. Particular values of the computed parameters aid in determining the etiology of hypertension and direct selection of pharmacotherapy.

Abstract: A method of assembling a print head that includes the steps of: (a) providing a print head base including a nozzle and at least one ink channel; (b) mounting in fluid communication with the at least one ink channel of the print head base an ink regulator that includes: (i) a pressurized chamber including an ink inlet in fluid communication with an ink source, an ink outlet in fluid communication with the at least one ink channel of the print head base, and an exterior flexible wall having an inner surface facing an interior of the pressurized chamber, (ii) a valve biased to restrict fluid communication between the ink source and the pressurized chamber, where the exterior flexible wall actuates the valve to overcome the bias in response to a predetermined pressure differential across the exterior flexible wall to provide fluid communication between the ink source and the pressurized chamber, where the fluid communication between the pressurized chamber and the ink source decreases the pressure differential ac

Abstract: Methods and systems are provided for acquiring seismic data. An ambient electromagnetic signal having a known time dependence is transmitted for propagation within a survey area. The ambient electromagnetic signal is received at distinct geographic locations with independently operating data acquisition units positioned at the distinct locations. Data representing acoustic signals received from the Earth at the distinct geographic locations are collected with the data acquisition units. The collected acoustic signals for the distinct geographic locations are synchronized by correlating the known time dependence of the propagated electromagnetic signal with time dependencies of the collected acoustic signals.

Abstract: A self-contained data acquisition unit is provided for acquiring seismic data. The unit has a microprocessor and an antenna adapted to receive an electromagnetic signal. A decoder is connected with the microprocessor and adapted to convert received electromagnetic signals to dual-tone multiple-frequency (“DTMF”) digits. A geophone interface is provided with a geophone for collecting acoustic data incident on the geophone. A memory is connected with the geophone interface for storing a representation of the collected acoustic data and for storing a representation of a reference electromagnetic signal to be used in synchronizing acoustic data collected by other data acquisition units. A battery power source is connected with the microprocessor.

The data offload and charging unit comprises a frame that defines stations for holding the data acquisition units and a host computer. A combined power and communications port at each such station is adapted to interface with one of the data acquisition units such that power may flow from the data offload and charger unit to that data acquisition unit and data may flow from that data acquisition unit to the host computer substantially simultaneously. Communications links are provided between the host computer and each combined power and communications port.

Abstract: The present invention relates to an immunoassay for simultaneously measuring the presence of antibodies to a plurlity of HPV types that utilizes particle-based flow cytometric analysis. The presence and/or titre of neutralizing antibodies in a test sample are determined in a competitive format, where known, type-specific, fluorescently labeled neutralizing monoclonal antibodies compete with antibodies within a test sample for binding to conformationally sensitive, neutralizing epitopes on specific HPV-VLPs. The invention also provides a microsphere complex comprising a microsphere coupled to an HPV VLP.

Abstract: In a system for laser welding work pieces along a collapsing weld interface, methods and apparatus include providing welding pads and/or stop projections on either or both of the work pieces to control the manner or amount of collapse. Preferably, the stop projections exist a separation distance from the weld interface while the welding pads exist at and form a portion of the weld interface. Buffers are taught between the weld interface and stop projection. The work pieces may comprise inkjet printhead lids and bodies. In another aspect, the invention teaches methods of laser welding inkjet printhead lids and bodies according to whether the inkjet printhead body embodies a mono or color ink body type and especially includes selective control of one or more laser light sources to illuminate the inkjet printhead lid in a specific pattern of light.
