Described herein are methods and systems for controlling a sensor assembly with a plurality of same type sensors. Sensors are operated in active and inactive states. The activation state of at least one of the sensors is changed based on an operational parameter that relates to an environmental condition differentially affecting the plurality of same type sensors.

Method and system for sensor configuration

A semiconductor package with design features, including an isolation structure for internal components and a flexible electrical connection, that minimizes errors due to environmental temperature, shock, and vibration effects. The semiconductor package may include a base having a first portion surrounded by a second portion. A connector assembly may be attached to the first portion. The connector assembly may extend through an opening in the base. A lid attached may be attached to, at least, the second portion. The attached lid may form a hermetically-sealed cavity defined by an upper surface of the first portion, the connector assembly, and an inner surface of the lid. An elastomer pad may be on the first portion and a sub-assembly may be on the elastomer pad. A flexible electrical connection may be formed between the connector assembly and the sub-assembly.

Semiconductor package with built-in vibration isolation, thermal stability, and connector decoupling

A sensor may be automatically calibrated during manufacture by providing a sensor processing unit having an integrated sensor, performing a check to determine if the integrated sensor has been previously calibrated upon a reset. When it has been determined the integrated sensor has not been previously calibrated, an automated calibration pattern may be imparted to the sensor so that a calibration parameter is determined.

Method and system for automatic factory calibration

Described herein are methods and systems for configuring a motion sensor assembly to compensate for a temperature gradient. First and second sensors of the same type are arranged as opposing pairs with respect to a first axis that may be defined by a temperature gradient caused by at least one thermal element. Combining the output measurements of the first sensor and the second sensor allows effects of the temperature gradient on sensor measurements of the first sensor and the second sensor to be compensated.

A hearable comprises at least one microphone coupled with a wearable structure and a sensor processing unit disposed within the wearable structure and coupled with the microphone. A portion of the wearable structure is configured to be disposed within a user's ear. The sensor processing unit acquires audio data from the at least one microphone and head motion data from at least one motion sensor of the sensor processing unit. The head motion data describes motions of the user's head and comprises cranium motion data and mandible motion data. The sensor processing unit separates the mandible motion data from the head motion data, synchronizes the mandible motion data and the audio data into a synchronized data stream; classifies an activity of the head during a portion of the synchronized data stream; and generates a health indicator for the user based on the activity and the synchronized data stream.

Described herein are methods and systems for controlling a sensor assembly with a plurality of same type sensors. Sensors are operated in active and inactive states and have a corresponding performance parameter and reliability parameter that may be determined. The activation state of at least one of the sensors is changed based on an operational parameter. The performance parameter and/or the reliability parameter can then be updated.

A portable device is provided having a motion sensor and an engagement sensor. A determination may be made whether the portable device is engaged with the platform. The data being output by the sensor may be used accordingly.

Systems and methods for determining engagement of a portable device

A synchronization system for an acoustic signal-based and inertial signal-based positioning system is provided that generates a magnetic field as a synchronization signal. The modulated magnetic synchronization signal is transmitted by a transmitter of the positioning system and received by the receiver of the positioning system. The receiver may make an acoustic position determination for the transmitter based on a received modulated synchronization signal and may make an inertial position determination for the transmitter based on the received inertial signal, such that the acoustic position determination and the inertial position determination are fused.

System for fusing acoustic and inertial position determination

A medical device comprises a surface, an ultrasonic sensor, and a processor. The surface is configured to interact with skin of a patient during operation of the medical device. The ultrasonic sensor is disposed beneath the surface and configured to ultrasonically measure data with respect to a region above the surface. The processor is coupled with the ultrasonic sensor. Responsive to detection of a finger in contact with the surface, the processor is configured to operate the ultrasonic sensor to capture a fingerprint of the finger. Responsive to authentication that a person associated with the captured fingerprint is authorized to use the medical device, the processor is configured to activate operation of the medical device.

Described herein are methods and systems for configuring sensors to compensate for a temperature gradient. Multiple sensor sets, each having at least two sensors of a same type with orthogonal axes, are positioned to form at least one opposing sensor pair, in which an axis of one sensor of one sensor set is in an opposite orientation to an axis of one sensor of another sensor set. A combined measurement of each opposing sensor pair may be output which is compensated for an effect of a temperature gradient on sensor measurements of the sensors.

In a method of motion sensor calibration, a motion with which to calibrate a motion sensor is determined. The motion sensor is controlled by a sensor processor and the motion sensor is comprised within a user interface that is coupled with a gaming engine. The sensor processor and the gaming engine coordinate regarding the motion. The sensor processor monitors the motion sensor for evidence of the motion made as a user input via the user interface in response to game content implemented by the gaming engine, based on the coordination, to incite the motion. The sensor processor calibrates the motion sensor with the motion.

A pressure sensor of a mobile device may be corrected by receiving reference pressure information from an associated device. The correction using differential pressure measurements may be influenced by one or more determined condition characteristics.

A parameter may be established with the user authentication application so that the other application runs with the at least one parameter.

A security system for a building comprises a pressure sensor and a computer system communicatively coupled with the pressure system. The pressure sensor coupled to a movable portion of a window in the building. The computer system is configured to: receive a first pressure measurement from the pressure sensor; compare the first pressure measurement to a reference pressure measurement; and based on the comparison, detect that the movable portion of the window has moved.
