Title: Method and apparatus for generating platform-standard object files containing machine-independent code
Inventor: LEWIS BRIAN T
IPC: G06F9/45
Filed: 1995-12-20
Abstract: A method and apparatus for generating a platform-standard object file containing machine-independent abstract code. Source code which defines a procedure is converted into abstract code which makes no assumptions about the platform on which the procedure will be executed. An abstract code platform-standard object file is generated based on the abstract code. The abstract code platform-standard object file includes a list of definitions of any global variables defined in the abstract code, a list of symbol references indicative of any external variables or external procedures referenced in the abstract code, a sequence of machine instructions for calling an execution routine when a client calls the procedure, and the abstract code which defines the procedure. The abstract code is preferably compressed before it is stored in the abstract code platform-standard object file. When a program including the abstract code platform-standard objectfile is executed, it is dynamically linked to the execution routine. When the procedure is called, the execution routine is invoked. The execution routine executes the procedure by interpreting the abstract code or generating machine-code responsive to the abstract code. The execution routine may be an execution control unit which selects between various execution techniques based on runtime factors, such as the frequency with which the procedure is called.

Title: Integral missile antenna-fuselage assembly
Inventor: FACCIANO ANDREW B
IPC: F42B15/00
Filed: 1995-12-22
Abstract: An integral missile antenna-fuselage assembly (50) is provided for integration into an armament missile  (12) which  carries  primary missile  loads,  houses  internal electronic assemblies, provides mounting surface zones for external  sensor antennas  (71),  and protects  sensitive antenna components from supersonic aerodynamic heating. Each end of the fuselage assembly (50) is formed from a fastener ring  (52,54)  having a circumferential  recess (84,86)  which receives a filament wound main structure (60)  to form the missile fuselage tube.   Preferably, a titanium liner (58) is first joined to each fastener ring with a step-lap joint (94,96) along which it is adhesively bonded.    The  liner (58)  and  adjacent  fastener  ring portions   (52,57)   provide   a  mandrel on  which  a graphite/Bismaleimide  (BMI)  resin pre-preg is  filament wound and  co-cured to form the integral fuselage (60). A plurality of Graphite/BMI doublers  (62,63,64,65)  are axisymmetrically  positioned  on  the  fuselage  external surface to form four antenna cavities (66,67,68,69) which receive antennas  (71)  therein.   Subsequently,  antenna spacers (72,73,74,75) encase the antennas (71) about which a radome overwrap (70) is filament wound with a Quartz/BMI pre-preg.   The entire structure (70) is then integrally cured to the internal fuselage (60) and antenna spacers (72,73,74,75) afterwhich it is surface treated (76)  and overcoated (78).

Title: Assured-Integrity Monitored-Extrapolation Navigation Apparatus
Inventor: DIESEL JOHN W
IPC: G01S1/00
Filed: 1995-06-07
Abstract: The assured-integrity monitored-extrapolation (AIME) navigation apparatus (1) selectively utilizes measurements provided by ancillary sources at periodic intervals in determining the state of the platform on which the apparatus is mounted.  The measurements have attributes which are measures of quality, quality being a measure of the usefulness of the measurement in accurately estimating the state of a platform. The AIME apparatus (1) makes its selection of measurements for state determination on the basis of estimates of the values of these quality attributes.  The determination of the quality of a time sequence of measured values of a particular quantity requires an evaluation time for its accomplishment.  The AIME apparatus (1) therefore determines the platform's state in two phases.  It obtains highly-accurate determinations of the states of the platform at times prior to present time minus the evaluation time by using the quality measures available at these times and using only those measurements that are determined to be of high quality in the determination of state at these times.  The platform state at present time is then obtained by extrapolation of the highly-accurate state at time minus the evaluation time using measurements whose quality is more uncertain.  The ancillary sources consist of a GPS receiver (3) and an inertial reference system (5).

Abstract: Methods, devices, apparatus and kits for amplifying and detecting nucleic acid are provided. The apparatus is a one or two-tier thermal cycling device (16) that operates in conjunction with a reaction/detection unit (20). A sample (38) is loaded into a reaction chamber (30) of the device which is then mated with a detection chamber (32) to form the reaction/detection unit.  A first heating element (90) of the thermal cycling apparatus applies a desired temperature to the reaction/detection device to amplify target nucleic acid in the sample. The reaction mixture is then transferred to the detection chamber by the second heating element (92) and amplified target nucleic acid is immobilized on a support in the detection chamber. Microprocessor control controls the heat applied by the second element independently of the heat applied by the first element.  A detection system associated with the apparatus detects and analyzes the immobilized amplified nucleic acid target.  Images are captured and digitized and subjected to statistical analysis to improve the accuracy of the method.
