A system determines the vertical position of an object and report that vertical position in a format suitable for use on a television broadcast, a radio broadcast, the Internet or another medium. One example of a suitable use for the system includes determining the height that a basketball player jumped and adding a graphic to a television broadcast that displays the determined height. The system includes two or more cameras that capture a video image of the object being measured. The object's position in the video images is determined and is used to find the three dimensional location of the object. The three dimensional location includes a height coordinate. In some cases, the height coordinate is the desired vertical position. In other cases, the height or size of the object may be subtracted from the height coordinate to determined the vertical position.

The present invention is directed to automated apparatuses and methods for measuring fastener hole depth, fastener length, countersink depth and/or hole diameters in a workpiece (or other object) in an automated and extremely rapid, efficient and accurate manner. The apparatuses may be operably connected with a power source and with one or a plurality of computers or other data collection devices to transmit fastener hole depth, countersink depth and/or hole diameter measurement data and/or information to them each time that a fastener hole is measured, while the apparatus is continuously measuring fastener holes (i.e., with no interruptions). Extremely advantageously, using only one hand, and by only squeezing a trigger only one time, an operator of such an apparatus may successfully and very rapidly and accurately perform more than one, or all three, of the following functions: (i) normalize the apparatus relative to one or a plurality of fastener holes and/or workpiece surfaces; (ii) make one or a plurality of accurate measurements; and (iii) transmit the one or more measurements from the apparatus to one or a plurality of computers and/or other data collection devices for, for example, recordation, storage, manipulation, other use and/or the like.

An apparatus for measuring the weight of items on a conveyor includes a scale that generates a first signal corresponding to the weight of the items. A movable platform transports the items to the scale and generates a second signal corresponding to position of the items in relation to the scale. A dimensioner examines the items and generates a third signal representative of whether the items are singulated or nonsingulated. A processor receives the second and third signals and determines whether to associate the first signal with information stored in memory about a particular item based upon whether the particular item is singulated or nonsingulated.

An apparatus, method and program for outputting a present position that enables a user to be located with further accuracy even in a multi-level area. A control unit periodically sends a reference atmospheric pressure information obtaining request to a base station and obtains reference atmospheric pressure information including the atmospheric pressure and altitude of the base station from the base station and stores the obtained information in a data storage. The control unit uses the measurement value of atmospheric pressure obtained from a pressure sensor and an altitude calculation equation including the reference atmospheric pressure information to periodically calculate and record in the data storage the altitude of the present position. When an emergency button is pushed, the control unit issues to an emergency contact an emergency notification including the present altitude or the altitude recorded in the data storage.

A method and apparatus for deriving performance statistics from real time tracking of a sporting event. The method according to the present invention includes a step of obtaining a spatio-temporal trajectory corresponding to the motion of an athlete and based on real time tracking of the athlete. The trajectory is then broken down so that performance information corresponding to the motion of the athlete (such as speed, distance covered, acceleration, etc.) can be derived with respect to time. The information so obtained can be stored in a database or the like for later retrieval or can be used to graphically supplement a video broadcast of a sporting event. The apparatus includes a device for obtaining the trajectory, a computational device for obtaining the performance information based on the obtained trajectory, and a statistical device for compiling the performance information. In particular, the spatio-temporal trajectory may be obtained by an operation on a video image of the sporting event, in which motion regions in the image are identified, and feature points on the regions are tracked as they move, thereby defining feature paths. The feature paths, in turn, are associated in clusters, which clusters generally correspond to the motion of some portion of the athlete (e.g., arms, legs, etc.). The collective plurality of clusters corresponds with the motion of the athlete as a whole.

The present invention is a system and method for generating an alarm relative to effective longitudinal behavior of a drill bit fastened to the end of a drill string driven in rotation in a well by a driving device situated at the surface, using a physical model of the drilling process based on general mechanics equations. The following steps are carried out: the model is reduced so to retain only pertinent modes, at least two values Rf and Rwob are calculated, Rf being a function of the principal oscillation frequency of weight on hook WOH divided by the average instantaneous rotating speed at the surface, Rwob being a function of the standard deviation of the signal of the weight on bit WOB estimated by the reduced longitudinal model from measurement of the signal of the weight on hook WOH, divided by the average weight on bit WOB0, defined from the weight of the string and the average weight on hook. Any danger from the longitudinal behavior of the drill bit is determined from the values of Rf and Rwob.

In illustrative implementations, a time-of-flight camera robustly measures scene depths, despite multipath interference. The camera emits amplitude modulated light. An FPGA sends at least two electrical signals, the first being to control modulation of radiant power of a light source and the second being a reference signal to control modulation of pixel gain in a light sensor. These signals are identical, except for time delays. These signals comprise binary codes that are m-sequences or other broadband codes. The correlation waveform is not sinusoidal. During measurements, only one fundamental modulation frequency is used. One or more computer processors solve a linear system by deconvolution, in order to recover an environmental function. Sparse deconvolution is used if the scene has only a few objects at a finite depth. Another algorithm, such as Wiener deconvolution, is used is the scene has global illumination or a scattering media.
