Headgear includes one or more sensors that provide input information to a controller of the headgear. The sensors may include accelerometers, location sensors, wireless receivers, cameras, and so on. The controller may receive the input information that is indicative of an orientation of the headgear, a location of the headgear, a communication signal, and/or an image or video. The headgear may also include one or more output devices that may be controlled by the controller (e.g., actuators, electronic displays, lights, speakers, and/or communication interfaces). As such, the headgear may output instructions to actuate an actuator, display an image on an electronic display, activate a light, emit a sound using a speaker, and/or send a communication signal using a communication interface. In particular, the headgear may determine an instruction to send to an output device in response to receiving the input information, and send the instruction to the output device.

A sensor system includes a drum, a first sensor, and a second sensor. The drum is mounted for rotation about a rotation axis and includes a band and a plurality of members that extend axially away from the band. The first sensor and the second sensor are configured to generate electrical output in response to detecting one or more of the plurality of members.

A method and apparatus for evaluating the driving of a vehicle performing a journey on a road network is disclosed. The method comprises determining a fuel usage rate and an engine speed of a vehicle, and determining when the vehicle is coasting based upon at least one of the fuel usage rate and the engine speed of the vehicle. An acceleration of the vehicle, when the vehicle is determined to be coasting, is compared with a predetermined reference acceleration, and an application of braking during the coasting is determined based on the result of the comparison. A method and apparatus is also disclosed for determining a score indicative of the relative amount of time for which the vehicle is coasting without braking during a journey.

A system for collecting and managing parametric data via an external communications network comprises one or more parametric stations operatively connected via the external network to a certification server and a payout server. Each parametric station is configured to receive parametric data from a remote source, determine that the parametric data satisfies a predetermined condition, and transmit the parametric data over the external network to the certification server in response to the parametric data satisfying the predetermined condition. The certification server is configured to generate a certification report based on the parametric data and a data model related to the remote source and transmit the generated certification report to the payout server. The payout server is configured to determine that terms of an associated contract are satisfied based on the certification report, and trigger a payout based on the terms that are satisfied based on the certification report.

Provided is an impact point estimation apparatus for estimating an impact point on a face surface of a head when a golf club having a grip, a shaft and the head is swung and hits a golf ball. The apparatus has an acquisition unit, a calculation unit, and an estimation unit. The acquisition unit is configured to acquire time series sensor data that is output from at least one of an angular velocity sensor and an acceleration sensor that is attached to at least one of the grip and the shaft. The calculation unit is configured to calculate a characteristic value of an initial stress wave that occurs due to impact from the sensor data acquired in an analysis period including an initial period after impact. The estimation unit is configured to estimate the impact point on the face surface, according to the characteristic value. The analysis period is before a predetermined short time period has elapsed from impact.

A method at a sensor apparatus, the method including calculating a value for a target function based on at least one sensor of the sensor apparatus; determining that the value of the target function is within a defined threshold range for a defined time period, thereby finding an in-flight state for the sensor apparatus; and turning off transmission from a radio of the sensor apparatus based on the in-flight state.

A method and apparatus for providing an indication to a driver of a geared vehicle that the vehicle is not in an optimal gear is disclosed. The method comprises determining a current gear of the vehicle and determining a current speed of a drive unit of the vehicle. An indication is then provided to the driver of the vehicle that the vehicle is not in an optimal gear when: (i) the determined current speed of the drive unit is greater than a predetermined threshold; and (ii) the determined current gear of the vehicle is less than a maximum gear of the vehicle. A method and apparatus is also disclosed for determining a score indicative of the amount of time during a journey on a road network that a geared vehicle is driven in an optimal gear.

A chronograph system with a frame, at least two sensors, and a computing device. The frame is configured to removably couple to a barrel of a firearm. The sensors are attached to the frame and are configured to detect a projectile as the projectile passes each sensor. The chronograph system is configured to use data received from the at least two sensors regarding each projectile to determine a velocity of each projectile and create velocity data based on the velocity of each projectile. The computing device is configured to communicatively couple to the chronograph system and display the velocity data to a user of the firearm.

A method and apparatus is disclosed for evaluating the driving of a vehicle performing a journey on a road network, comprising determining at least one constant speed zone of the road network, a constant speed zone being a portion of the road network at which the vehicle can travel at a constant speed, said determination being based upon expected speeds of travel along the road network determined from positional data relating to the movements of a plurality of vehicles over time along the road network. A speed of the vehicle traversing the road network is determined at a plurality of times during the journey, and a value indicative of a consistency of the speed of the vehicle within the at least one constant speed zone is further determined.

A method of operating a controller includes: obtaining calibration data for a mounting orientation of the controller operating in a calibration mode based on obtaining first acceleration samples from an acceleration sensor; obtaining second acceleration samples from the acceleration sensor when a control switch is activated with the controller operating in a normal operating mode; performing a comparison of the second acceleration samples to the calibration data; based on the comparison, determining whether more than one of the second acceleration samples is not within a specified range; and in response to determining that more than one of the second acceleration samples is not within the specified range, causing the controller to operate in an anti-tamper mode.
