Abstract:
The system that enables the classification and description of goods is described. The system is based on a combination of a user device with a graphical user interface that captures images, video, and/or audio of an object, such as farm equipment or construction equipment. The user device provides the information to a computing device running a classification model trained through machine learning. Training data may include sensor data (e.g., multimedia data such as images, video, and audio) depicting existing equipment in various configurations and corresponding data sets characterizing the equipment in those configurations.

Abstract:
The invention is a method for enabling digital content to be downloaded to and used on multiple types of computing device by (i) linking user accounts on each device to a “master” user account defined and stored on a remote server; and (ii) managing the user's access to a defined service using his devices via the said master user account; and (iii) allowing the download of digital content to each said device on which the user is permitted to access the said service using a file format which is appropriate for use on each said device type. A user may manage and access the same user account from multiple types of computing devices. Furthermore, the number of device platforms accessible in a similar manner by the user is extensible and the user's information is kept automatically synchronized across all devices.
Abstract:
A GPS receiver acquires carrier frequency and Gold code phase using short segments of a received GPS signal. In one embodiment, a 1-ms segment of the GPS signal is transformed to the frequency domain. This is multiplied by a frequency representation of the Gold code. The resulting product is converted to the time domain, and a peak is detected. The location of the peak corresponds to the code phase. If no peak is located, the carrier frequency is changed. Full- and half-bin steps in carrier frequency are considered. Processing gain is achieved by using longer segments of the input signal, for example 4 or 16 ms and integrating 1-ms segments. Considerations are provided for compensating for the effects of a transition, should it occur in the short segment of the GPS signal being processed. Integrations can be performed using non-coherent and coherent techniques. Adjustments are made for non-integral millisecond segment lengths.
Abstract:
A frequency translator uses a CORDIC phase rotator coupled to a phase accumulator to translate an input signal in frequency. The CORDIC phase rotator performs required phase angle rotations of input vectors using only shift and add operations. Thus, the frequency translator can be readily implemented in hardware. Higher precision arithmetic is used in the CORDIC phase rotator operations than the input vectors contain. To avoid truncation error at the output of the CORDIC phase rotator, stochastic rounding is employed. A dither signal is added to avoid errors due to nonlinear operation of D/A converters, where D/A conversion of the frequency translated signal is required.
Abstract:
Embodiments are generally direct to a method and apparatus to generate a data descriptor. In one embodiment, a data descriptor is generated for a block of data to be forwarded from a node to another node on a communication link. The data descriptor includes an indication to build a data packet containing at least a portion of the block of data in an accelerated or a non-accelerated manner.
Abstract:
A method for interactive evolutionary computing may include generating a solution set based on an evolutionary scheme in which an objective function is a priori mathematically unexpressed, presenting data based on the solution set to one or more users, receiving at least one input from the user(s), the input(s) based on the user(s)'s evaluation of the presented solution set, and, based on the input(s), using at least the evolutionary scheme and the input(s) to generate an updated solution set, and repeating the presenting and receiving.
Abstract:
A manipulator for a fiber optic cable assembly (FOCA) provides microradian accuracy in control of the direction of a beam emanating from the FOCA. Such manipulators can control FOCAs to control the incidence angles of beams at a beam combiner in a beam-combining unit. Accordingly, fewer additional optical elements are required for control of input paths in the beam-combining unit. The manipulator and the beam-combining unit are accurate enough for use in an interferometer that combines beams with different frequencies and polarizations. One such interferometer includes a Zeeman split laser providing a heterodyne beam. A beam splitter separates frequency components of the beams, and AOMs increase the frequency separation between the separated beams. The separated beams can be sent via optical fibers to the beam-combining unit, which combines the beams for use in interferometer optics.
Abstract:
A Low Earth Orbiting satellite system provides location and data communications to mobile users equipped with a receiver/transmitter, which acts as a transponder that responds to a query transmitted over the satellite network. The response is sent after a precisely controlled time interval after the transponder receives the query so that the ground station can estimate the propagation path length. The transponder also transmits the response at a frequency proportional to the frequency of the received query so that the ground station can estimate the first and second derivatives of the propagation path length according to the measured Doppler shift. The ground station also estimates the satellite positioning using satellite telemetry obtained from the on-board GPS receiver. The position of the user terminal relative to the satellite position is then determined from the path length measurements. Given the satellite position and velocity, the measured path length and first and second derivatives determine the angle between the direction of satellite motion and the line of bearing to the user terminal. This angle defines a cone with the satellite at the origin. The user terminal position is somewhere on the circle defined by the cone and the estimated path length. The intersection of this circle with the surface of the Earth yields two possible user positions, which ambiguity can be resolved by three techniques: (1) knowledge of which beam the signal was received in; (2) previously obtained position data; or (3) using nearby satellites to receive the signal.
