摘要： A method for performing magnetic resonance spectroscopy is described. The method generally includes applying a tailored multiband spectral-spatial radio frequency excitation pulse to a sample including a first species and at least a second species having a different resonant frequency than the first species. The multiband excitation pulse excites the first species according to a first amplitude and excites the second species according to a second amplitude that is substantially greater than the first amplitude. Data is acquired from the sample. The acquired data is then utilized to generate a spectroscopic output. By way of example, the spectroscopic output is a spectroscopic image. In particular embodiments, the data for the first and second species is acquired dynamically over an observation window of time.

摘要： A communication system adds transport layer protocol independent address labels to data packets. The communication system then routes the data packets based on the address labels rather than routing addresses, such as IP, UDP, and ATM headers, and thus can multiplex and transport data packets that are formatted based on a variety of transport protocols.

摘要翻译： 通信系统将传输层协议独立地址标签添加到数据包。 然后，通信系统基于地址标签路由数据分组，而不是诸如IP，UDP和ATM报头之类的路由地址，并且因此可以复用和传输基于各种传输协议格式化的数据分组。

摘要： A charge control system for lithium battery using pulse width modulation is provided, and it detects the existing voltage of the charging lithium battery by a voltage detector and passes this voltage value to a microprocessor preset in the hand-held apparatus. Thus, the microprocessor can decide the applicable charge stage and confirm the status of the charging battery depending on the different Voltage values in real time. Next, the microprocessor controls a control unit by a pulse width modulation signal to modulate the power-source, which comes from an adaptor, as a constant current or a constant voltage to charge the battery. Accordingly, the charge process is completed by repeating the voltage detection and the duty cycle modulation of the control unit.

摘要： The wireless communication apparatus includes a blue tooth wireless earphone that can be operated independently and a network phone base. The blue tooth wireless earphone is embedded into the network phone base. When the blue tooth wireless earphone is used independently, a voice is inputted and outputted via a microphone and a loudspeaker of the blue tooth wireless earphone, respectively. Once the blue tooth wireless earphone is used in combination with the network phone base, the voice is inputted and outputted via a microphone and a loudspeaker of the network phone base.
