This disclosure addresses providing gigabit-rate data transmission over wireless radio links, using carrier frequencies in the millimeter-wave range (>30 GHz). More specifically, a circuit for detection of amplitude-shift keyed (ASK) or other amplitude modulations (AM) which can be easily incorporated into an integrated circuit receiver system is described, making the receiver capable of supporting both complex IQ modulation schemes and simpler, non-coherent on-off or multiple-level keying signals. Several novel radio architectures are also described which, with the addition of a frequency discriminator network, have the capability of handling frequency shift keyed (FSK) or other frequency modulations (FM), as well as AM and complex IQ modulation schemes. These radio architectures support this wide variety of modulations by efficiently sharing detector hardware components. The architecture for supporting both quadrature down-conversion and ASK/AM is described first, followed by the ASK/AM detector circuit details, then the AM-FM detector architecture, and finally the most general AM-FM/IQ demodulator system concept and the FSK/FM detector circuit details.

A transverse form analog finite impulse response filter. The filter has an input and an output. A first set of passive delay elements connected in serial to the input, and a second set of passive delay elements are connected in serial to the output. Transconductors are connected in parallel with the first plurality of passive delay elements and the second plurality of passive delay elements. A set of buffer amplifiers is connected to the passive delay elements in the first set of passive delay elements and in the set of passive delay elements. The buffer amplifiers cause a reduction in loss in the passive delay elements.

A method and structure for a phased-array system. An orthogonal signal generator generates a plurality of signals C(i) that are orthogonal or near-orthogonal, meaning that a cross correlation between any two signals C(i) is lower than autocorrelation, and there is a plurality of phased-array antenna elements, each said antenna element providing a signal Sinp(i). A multiplier multiplies each signal C(i) with the signal Sinp(i) of a corresponding one of the plurality of phased array antenna elements.

A system and method is provided for managing energy data. The system includes a energy transformation device, a central energy data management system and a database containing carbon dioxide credit information. Managing the energy data includes measuring an amount of power produced or consumed by an energy transformation device, measuring an amount of carbon dioxide emitted, converted or sequestered by the energy transformation device, creating a dataset of the power produced or consumed and the amount of carbon dioxide emitted or sequestered, and transmitting the dataset and characteristic data to a central energy data management system. The method also includes, receiving energy measurements and characteristic data from an energy transformation device, obtaining carbon dioxide credit information and comparing the received energy measurements and the characteristic data with the received carbon dioxide credit information to obtain a carbon dioxide credit for the energy transformation device.

A method for charging electric vehicles includes receiving information regarding an electric vehicle. At least a portion of the information is received through a vehicle interface configured to place a battery of the electric vehicle into electrical communication with a fuel cell system. A charge is delivered from the fuel cell system to the battery of the electric vehicle through the vehicle interface without use of a direct current to alternating current (DC/AC) converter. The charge is delivered based at least in part on the information.
摘要:
A system for generating a sequence of learning objects comprising an e-Learning course is provided. The system can include one or more processors and a memory unit for electronically storing data comprising a plurality of learning objects. The system further can include a sequence builder configured to execute on the at least one processor. The sequence builder, more particularly, can be configured to generate a sequence comprising at least a portion of the plurality of learning objects based upon a measurable user relevancy and/or a measurable query relevancy of each learning object contained in the sequence.
摘要:
A portable data terminal generally includes a housing supporting: a data collection device; a keypad; and a touch screen. One or more PDTs are provided with a monitoring system that records occurrences experienced by the portable data terminal. The record of occurrences may be analyzed to identify errors and/or failure prone parts of the PDT along with behaviors likely to lead to errors or failures. Additionally, the record of events may be analyzed to predict errors and/or failures for any given PDT.

Spectrum analyzer circuits and methods are provided which implement “zero-IF” (direct conversion) or “near-zero IF” (or very low IF) architectures that enable implementation of integrated (on-chip) spectrum analyzers for measuring the frequency spectrum of internal chip signals. An integrated spectrum analyzer circuit, which comprises a zero IF or near-zero IF framework, enables a low-power compact design with sufficient resolution bandwidth for on-chip implementation and diagnostics of internal chip signals.
