摘要： An Instrumented Spherical Blast Impulse Recording Device (ISBIRD) provides for survivable test measurement of an explosive blast impulse. The ISBIRD includes a spherical housing formed of a metal having a thickness sufficient to survive the explosive blast wave from a test weapon. A test data module of the ISBIRD includes: (i) a three-axis acceleration sensor; (ii) a memory; and (iii) a controller communicatively coupled to the three-axis acceleration sensor and the memory. The controller executes a data acquisition utility to record acceleration data in three-dimensions from the three-axis acceleration sensor during exposure of the spherical housing to the explosive blast wave. An internal support structure of the ISBIRD is attached inside of the spherical housing and attached to the test data module. The internal support structure centrally locates the test data module within the spherical housing during exposure to the explosive blast wave.

摘要： One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.

摘要： A display device, for a hybrid vehicle for displaying an output relating to traveling of the hybrid vehicle, includes a first region and a second region. The first region indicates the output in a first mode in which an internal combustion engine is stopped and the vehicle travels using an electric motor. The second region indicates the output in a second mode in which the internal combustion engine is operated to travel. The first region and the second region are independently disposed in a predetermined range. Numerals for scale are marked in either one of the first region and the second region.

摘要： A fault indicator for indicating the occurrence of a rapid pressure surge within a housing of an electrical device has: a barrel capable of being mounted in an aperture of the housing; an actuating mechanism having a chamber with at least one orifice communicating between interior and exterior surfaces of the chamber within the housing and an actuating member movable in response to a pressure differential between the interior and exterior surfaces of the chamber; a plunger within the bore of the barrel biased outwardly in the barrel and normally retained in an armed position by the actuating member; and a radial seal disposed between the plunger and the barrel. When the pressure differential exceeds a positive threshold value, the actuating member is moved and thereby permits the plunger to move outwardly into a triggered position. The radial seal may be a dual-lip seal.

摘要： A sensor head characterizes unsteady pressures in a fluid flowing within a pipe, as may be caused by one or both of acoustic waves propagating through the fluid within the pipe and/or pressure disturbances that convect with the fluid flowing in the pipe. The sensor head comprises a rigid support structure and at least one transducer attached to the rigid support structure. The rigid support structure holds the transducer in contact with an outer surface of the pipe. The at least one transducer senses relative movement between the outer surface of the pipe and the support structure and provides a signal indicative of unsteady pressures within the fluid at a corresponding axial position of the pipe in response to the relative movement. The support structure may be attached to each transducer in an array of transducers, and may include a handle secured thereto for manipulating the sensor head into contact with the pipe. Output signals from the transducers are provided to a processing unit, which processes the output signals to provide a signal indicative of at least one parameter of the flow process.

摘要： A copper crusher gauge holder for testing internal pressures of cartridgesuring test firing is provided. The copper crusher gauge holder has a circular aluminum upper plate and a circular aluminum lower plate having a layer of urethane rubber approximately 3/4 inch thick sandwiched between the plates. The gauge holder is bored to hold copper crusher gauges and center-bored to fit over a cartridge centerline primer tube. A series of machine screws hold the plates together and allow for tightening the screws once the copper crusher gauge holder is in place in a cartridge to be tested. As the machine screws are tightened, the urethane rubber expands laterally gripping the inside of the cartridge and gripping the copper crusher gauges. A method to manufacture the gauge holder is provided.

摘要： A probe (P) capable of sensing acoustic and hydrodynamic pressures in a heated flow field and an associated apparatus for acoustically exciting the heat flow (35), for positioning the probe (P) within the flow field and fro acquiring data. The probe (P) consists of a miniature microphone (10) mounted in an assembly which provides direct water cooling to the microphone body and which, by means of a bullet nosed extension (23, 24) with lateral ports (25), protects the microphone element (10) from direct impingement of the flow (35). Acoustic excitation of the flow (35) is introduced upstream of the nozzle (34) through a tube (37) from an externally mounted acoustic driver (36) which responds to the amplified output of a signal generator (38); the signal generator (38) and the amplifier (39) are adjusted to control the frequency and amplitude of the excitation. A traversing mechanism (32), capable of movement in three orthogonal directions is used to position the probe (P) within the flow (35). Signals from an acoustic excitation sensor (47) and from the probe (P) are amplified to convenient levels and processed by a two-channel Fast Fourier analyzer (40) which produces the transfer function correlograms and spectra of the input signal individually and jointly displayed on a recorder/indicator (41).
