A method for obtaining a position of a peripheral device for an audiovisual entertainment system, the method comprising: controlling an audio source to output an audio signal at a first time; determining a second time at which the audio signal arrives at an audio detector, wherein the peripheral device comprises at least one of the audio source and audio detector; and estimating a position of the peripheral device based on an acoustic time-of-flight between the first time and the second time

Methods, apparatus, systems and articles of manufacture to detect changes in a physical environment are disclosed. An example apparatus includes a descriptor generator to generate a first descriptor, the descriptor generator including: a chirp producer to emit a chirp into the environment, a chirp recorder to record a response to the chirp from the environment, and a chirp response encoder to generate an encoding of the response to the chirp; a descriptor similarity generator to generate a similarity value, the similarity value to compare the first descriptor to a second descriptor; and a physical change indicator to, in response to the similarity value exceeding a similarity threshold, indicate that a physical change has occurred in the environment.

An apparatus including at least one emitter configured to emit energy; at least one receiver configured to receive the emitted energy, where the at least one emitter is mounted on at least one of: a robot arm, an end effector of the robot arm, a substrate on the robot arm, or a substrate process module, where the at least one receiver is mounted on at least one of: the robot arm, the end effector of the robot arm, the substrate on the robot arm, or the substrate process module.

To obtain an appropriate evaluation value in an acoustic quality evaluation by a conversational test. An acoustic quality evaluation apparatus 3 evaluates the acoustic quality of a call performed between a near-end terminal 1 and a far-end terminal 2 via a voice communication network 4. An evaluation value presenting unit 31 displays, on a display unit 13, evaluation categories obtained by classifying each of a plurality of evaluation viewpoints into a predetermined number of levels. An input unit 14 transmits the evaluation category selected by the evaluator for each of the evaluation viewpoints, to an evaluation value determination unit 32. The evaluation value determination unit 32 determines the lowest evaluation value among evaluation values assigned to the evaluation category received from the input unit 14 as a subjective evaluation value for acoustic quality.

A user computing device for identifying a driver of a vehicle on a trip is provided. The user computing device is associated with a first vehicle occupant, and is programmed to: (i) detect a second user computing device associated with a second vehicle occupant, (ii) initiate a ping exchange process including emitting a set of non-audible sonic ping signals and detecting a set of signals from the second user computing device over a duration of the trip, (iii) generate a relative positioning map of the user computing device with respect to the second user computing device, (iv) determine that the first vehicle occupant is one of a driver and a passenger of the vehicle, and (v) transmit, to a driver identification (“DI”) server, a trip report including the determination and the generated relative positioning map.

A periphery recognition support system for a personal watercraft includes processing circuitry. The processing circuitry is configured to: receive position related data related to a positional relation between a personal watercraft and a peripheral object around the personal watercraft; determine based on the position related data whether or not a predetermined warning condition is satisfied; and output a predetermined warning signal when it is determined that the warning condition is satisfied.

A kind of real-time measurement system and method for height from spray boom to crop canopy was provided in present invention patent, which includes the following steps. Step 1: Calibration for ultrasonic ranging sensor; Step 2: Determination of included angle for two ultrasonic ranging sensors; Step 3: Collection of relative height between spray boom and crop canopy; Step 4: Anti-interference processing for height data; Step 5: Calculation of relative height from spray boom to crop canopy. Its characteristic lies in: two ultrasonic ranging sensors with a certain angle are installed at each end of the spray boom, the height of crop canopy was acquired under the control of control unit, and the relative height from spray boom to crop canopy was obtained by the anti-interference analysis and data conversion, the accurate monitoring for relative height from spray boom to crop canopy was realized while the spray boom is tilted. It breaks through the technical bottleneck that the relative height of the spray boom and the crop canopy cannot be accurately obtained when the spray boom tilts due to turbulence in the field operation of the spray boom sprayer, and lays a technical foundation for the dynamic adjustment of the balance and height of the spray boom.

An apparatus, product monitoring system, and a method of measuring an amount of product on a roller are provided. The method includes receiving a first position distance between a position sensor and an exterior edge of the roller. The method also includes comparing the first position distance with a predetermined position distance. The predetermined position distance defines the distance between the position sensor and the exterior edge of the roller at a specific amount of product left on the roller. The method further includes determining the amount of product left on the roller based on the comparison of the first position distance and the predetermined position distance. The method still further includes causing the transmission of a signal relating to the amount of product left on the roller.

A mobile work machine includes a frame, a material loading system having a material receiving area configured to receive material and an actuator configured to control the material loading system to move the material receiving area relative to the frame, and a control system configured to receive an indication of a detected object, determine a location of the object relative to the material loading system, and generate a control signal that controls the mobile work machine based on the determined location.

A visual assistance system or distance and location detection system is provided. The system comprises a sensor detecting distance of objects in a user's path and alerting the user when an object is within a designated proximity to the user. The system further comprises a location detection system using GPS technology that tracks the user's location and issues an alert to the user or other individual when the user's location exceeds the boundaries of a designated safe zone.
