Apparatus and associated methods relate to a vehicle attitude estimated as a function of predicted acceleration from the vehicle control system. In an illustrative example, a weighting module may dynamically combine IMU (Inertial Measurement Unit) with sensor motion data motion profile information from the vehicle control system. The weighting module may receive the predicted acceleration information via a data link with the vehicle control system. The dynamic weighting of inputs may be processed by an attitude estimator. An estimated attitude may be supplied to a display device, for example, to represent a real-time spatial orientation of the vehicle with respect to the gravity vector.

Method, apparatuses, and computer program products for automatically tracking a heading of an object. An example method comprising receiving, one or more internal measurement values which pertain to an object; determining an internal heading uncertainty value for each internal measurement value of the one or more internal measurement values; generating, using a probabilistic heading model, an estimated heading data object for the object based at least in part on the one or more internal measurement values; and providing the estimated heading data object to one or more associated user devices.

Methods and apparatuses for automatic object heading determinations

Apparatus and associated methods relate to an unpowered data-transfer device having a processor, non-volatile memory, and two connection ports, from which operating current for the unpowered data-transfer device is drawn when connected to a powered system via one of the connection ports. In various embodiments, the apparatus may transfer program data or configuration data from a host processor system to one of a plurality of target data-transferable systems. Some embodiments may transfer stored data from one or more target data-transferable systems to a host processor system. Some exemplary unpowered data-transfer devices may include a power arbiter coupled to both a host port and a target port, the power arbiter determining from which port operating current may be drawn. In various embodiments, an unpowered data-transfer device may facilitate firmware upgrades or system settings changes to autonomous programmable systems by touching target port contacts to a port on a data-transferable system.

Unpowered data-transfer device

A wireless and batteryless pressure sensor apparatus comprises of a SAW sensor and an antenna mounted on a printed circuit board. Optionally, and RFID tag in used in combination with the SAW sensor. A sensor antenna and a RFID antenna can be located on the printed circuit board such that the antennas communicate electrically with the sensor and the RFID device. The sensor can be interrogated utilizing a radio frequency, which is used to excite a SAW crystal inside the sensor. The interrogation signal causes the SAW to resonate wherein a resonant frequency changes with the pressure and temperature that is applied to the sensor. An interrogator can receive a return (echo) signal representing a change in SAW sensor properties (e.g., diaphragm change). A printed circuit board can be mounted on a stainless steel port and overpackaged with standard processes for hermetically sealing the sensor, or sensor and RFID device with at least one antenna.

Surface acoustic wave sensor and package

The SAW sensor in a stainless steel button package having a diaphragm and mounted on a threaded port. Package can hermetically seal a sensor and RFID-antenna assemblies from media. Sensor diaphragm is exposable to media. Sensor and RFID antennas communicate electrically with SAW sensor and RFID device, respectively, for sensor measurements and identification. Antennas receive RF interrogation signal from a nearby interrogator/transceiver and send reflected RF signals back to the interrogator unit containing sensor measurement and sensor ID. TRF signal excites a SAW resonator inside the sensor and causes the SAW to resonate wherein resonant frequency changes with pressure and temperature applied to the sensor. Antennas could be printed circuit board antennas, helical antennas, loop antennas, any other commercially available off-the-shelf antennas or a combination of these.

Saw sensor button package

A method and apparatus, wherein a die is attached to a supporting base structure utilizing a rigid bond adhesive for a SAW (Surface Acoustic Wave) sensor. A rigid bond adhesive with a preferably high glass transition temperature (Tg) can be applied directly between the die and the die supporting structure in a pattern to eliminate time dependent gradual stress effects upon SAW sensor. The rigid bond adhesive can then be cured, which results in a high yield strength and a high young's modulus. The supporting base and the die material comprise a same co-efficient of thermal expansion in order to avoid die displacement over temperature.

Mechanical packaging of surface acoustic wave device for sensing applications

A surface acoustic wave die system and method are disclosed herein, including a surface acoustic wave sensor comprising one or more surface acoustic wave die disposed and hermetically sealed between a base and a cover. An adhesive is generally for securing one or more of the surface acoustic wave die to the base, which is configured with a pattern of cross hatches formed thereon in order to permit the adhesive to adhere to the base. The adhesive is placed under a location wherein surface acoustic wave die is to be located. The surface acoustic wave die is thereafter pressed into the adhesive, whereby upon a subsequent curing of the adhesive, the surface acoustic wave die is held securely in place, while remaining flexible as required by sensing applications associated with the surface acoustic save sensor.

Method of making a surface acoustic wave device

A wireless sensor fixture system and method are disclosed in which an antenna block is provided that includes a plurality of grooves, wherein such grooves maintain a plurality of antennas located on a portion of the antenna block. A top locator block can be positioned above the antenna block, wherein the top locator comprises a top surface having depression thereon for receiving and locating a patch, which can receives wireless signals from the antennas for sensor testing thereof, wherein the patch comprises a SAW sensor and an RFID tag over-molded into the patch. Additionally, an antenna cover can be connected to the antenna block for protecting the plurality of antennas and wiring thereof. A BNC connector protrudes from the antenna block and is electrically connected to the plurality of antennas via the wiring thereof.

Surface acoustic wave sensor and radio frequency identification interrogator fixture

A wireless sensor is disclosed, which includes a substrate upon which the wireless sensor can be configured. The wireless sensor includes a plurality of surface acoustic wave (SAW) sensing elements configured in parallel with one another upon the substrate, wherein one or more of the SAW sensing elements is responsive to a wireless frequency range that differs from that of a wireless frequency range of at least one other SAW sensing element among the group of SAW sensing elements. It is this parallelism that permits all of the SAW sensing elements to receive the same strain when pressure is applied thereon. In doing so, the capability for three separate interrogators to measure strain is provided. At any one location, however, only one style of interrogators can be employed, rendering two of the three SAW sensing elements useless, without interfering with the one SAW sensing element that is useful in order to permit a wireless interrogation of the wireless sensor despite varying international frequency standards thereof.
