Abstract: Centrifugal gyroscopic devices are described herein. A representative device can include a shaft, an arm coupled to the shaft, a rotor coupled to the arm, and a control system operably coupled to the shaft, the arm, and/or the rotor. The shaft is rotatable about a first axis and the arm is configured to rotate with the shaft. The arm is pivotable about a second axis and the rotor is configured to pivot with the arm about the second axis. The rotor is further pivotable about a third axis. The control system is configured to bring the shaft, the arm, and the rotor into a resonant mode in which the shaft rotates at a rotational rate, the arm oscillates about the second axis at a first frequency substantially equal to the rotational rate, and the rotor oscillates about the third axis at a second frequency substantially equal to the first frequency.

Abstract: The subject matter disclosed herein relates to the control and utilization of multiple sensors within a device. For an example, motion of a device may be detected in response to receipt of a signal from a first sensor disposed in the device, and a power state of a second sensor also disposed in the device may be changed in response to detected motion.

Abstract: Embodiments provided herein measure metrics of an athletic action and an object associated therewith, and more particularly, to measuring the metrics and characteristics of a baseball during the wind-up, release, flight, and catch of a pitch sequence. Methods may include: receiving, from at least one motion sensor associated with an object, acceleration data and angular velocity data of the object in response to an athletic action performed on the object; processing the acceleration data to establish vector rotation data between a frame of reference of the object and an Earth frame of reference; applying the vector rotation data to the acceleration data to obtain acceleration of the object in the Earth frame of reference; applying the vector rotation data to the angular velocity data to obtain angular velocity of the object in the Earth frame of reference.

Abstract: A storage box includes an outer cylinder and a frame. The outer cylinder has a sidewall with an opening. The frame is disposed inside the outer cylinder, and has a rotatable connection with the outer cylinder. A space between a surface of the frame and the sidewall of the cylinder forms a storage member. As the frame rotates relative to the outer cylinder, the opening and the storage member alternates between a first relative position and a second relative position.

Abstract: A controller and associated sensor system for augmenting the automatic delivery of drugs is provided. The controller and associated sensor system is based on the detection and determination of particular physical lifestyle events. As a specific example, a pump augmentation system includes a six-axis accelerometer sensor, a gyroscopic pitch sensor and a controller. The controller is configured to receive motion data from the six-axis accelerometer sensor and orientation data from the gyroscopic pitch sensor. The controller provides a pump instruction signal for changing a delivery rate of a drug to a user based on the motion data and the orientation data. When the pump is an insulin pump, the pump augmentation system is an insulin pump augmentation system and provides accurate insulin control for controlling blood glucose levels of a user.

Abstract: A computer system comprises a sensor device configured to attach to a rotating object. The sensor device has a gyroscopic sensor that is configured to measure rotational motion on one or more planes. The sensor device detects rotational movement and generates and transmits signals that represent the rotational movement detected to a mobile computing device. The mobile computing device receives the signals and assigns timestamp values to the signals. The mobile computing device also receives object parameter information that describes object attributes. The mobile computing device generates angular velocity datasets and object datasets that describe motion or positions of the object. The mobile computing device then generates sets of graphical representations from the object datasets and displays graphs from the sets of graphical representations, where each graph displayed is obtained from a distinct set of graphical representations.

In one embodiment, the electronic pourer includes an orientation determining subsystem configured to determine an orientation of the electronic pourer, a wireless communication subsystem, a processing subsystem having at least one processing core, and a power source configured to power up the electronic pourer. The processing subsystem can be coupled to the orientation determining subsystem and the wireless communication subsystem to determine whether liquid has been dispensed from the electronic pourer based on the angular displacement of the orientation determining subsystem, and transmit information to an external computing device via the wireless communication subsystem. In another embodiment, the electronic pourer is equipped with a subsystem.

Abstract: One or more embodiments are directed to zero-rate level compensation systems. One such system includes stationary detection circuitry that receives gyroscope signals output by a gyroscope and determines whether the gyroscope is stationary based on the gyroscope signals. The stationary detection circuitry generates a stationary gyroscope signal indicating the gyroscope is stationary based on a determination that the gyroscope is stationary. A temperature sensor senses temperature and outputs temperature signals. Zero-rate level estimation circuitry receives the stationary gyroscope signal and a temperature signal associated with the stationary gyroscope signal, and iteratively estimates one or more zero-rate level compensation parameters based on the stationary gyroscope signal and the temperature signal.
