摘要： A circuit is provided for creating a termination impedance which matches a characteristic impedance. The characteristic impedance of a system or network is matched by placing a nominal impedance across the transmission line. The difference between the nominal impedance and the characteristic impedance is synthesized such that the synthesized or generated impedance is in parallel with the nominal impedance. The parallel combination of the nominal impedance and the generated impedance produces a termination impedance which substantially matches the characteristic impedance. The generated impedance is created by sensing a voltage and scaling that voltage by a factor related to the nominal and characteristic impedances. The scaled voltage controls a current source which produces a current having a value related to the inverse of the impedance. The ration of the sensed voltage and the generated current is the impedance which, when combined with the nominal impedance, produces the desired termination impedance. In this manner, the characteristic impedance of the source is matched by the altered nominal impedance.

摘要： A method and apparatus for automatically switching between voice and data communications as directed by a voice and data capable modem via a cable assembly incorporating a switching means for facilitating and inhibiting the routing of voice information to a voice telephone. A voice and data capable modem incorporates the software functionality associated with a voice and data capable protocol with minimal impact to the form factor associated with the modem, To reduce the impact to the form factor associated with integrated modem designs, the switching hardware associated with voice and data capability is incorporated into a cable assembly used to interconnect the voice and data capable modem with the voice telephone. Additional means for identifying the cable assembly as having the requisite switching functionality is also provided.

摘要： A low power ultrasound system for use in sonography applications, including vascular imaging, is disclosed. In one embodiment, the low power ultrasound system comprises a base unit that includes an image processor and a display. An ultrasound probe is operably connected to the base unit. The probe includes a head portion including an array of crystal transducers. A plurality of pulser/receiver modules that cause the transducers to emit ultrasonic transmit pulses are also included in the probe. The pulser/receiver modules are further configured to receive analog signals relating to ultrasonic echo receive pulses detected by the transducers. The probe includes a singular low noise amplifier that amplifies the analog signals, and an analog-to-digital converter that converts the analog signals to a digital signal. A wireless interface is included for enabling the digital signal to be wirelessly transmitted from the probe to the image processor of the base unit.

摘要： Parallel data is serialized and transmitted and asynchronous data is received and placed into parallel bytes using a hardware assisted interface. The interface can be driven with very little overhead to the DSP. Additional timing registers and enhanced data buffers decrease the necessary DSP resource commitment. Furthermore the hardware settings in the interface can be adjusted by the DSP to optimize the interface's performance in transmitting various asynchronous protocols.

摘要： In a system having an DSP, an ASIC and a memory, in which the ASIC generates a number of different competing interrupts for the DSP to service, the ASIC has an interrupt request control module which automatically provides the DSP with a vector pointing to the memory location of the interrupt service routine for the currently pending interrupt request having the highest priority of all pending requests. The DSP reads this vector and uses it to access the interrupt service routine in the memory. Reading of this vector causes the interrupt request to be de-asserted, which causes the next highest priority pending interrupt request to become the highest priority pending interrupt request. As a result, a new vector is presented for the next read by the DSP.
