摘要:
RF devices used in financial and other transactions are moved sequentially to stations of a preparation device that prepares the RF devices for delivery to customers. At one station, an RF reader reads an identification code from the RF device and a label reader reads information on a mailing label. The read information is used to verify the mailing information to assure that the RF device is being delivered to the correct recipient.

Input stage having increased input signal noise margin and method for generating an output signal having a predetermined logic level based on the voltage level of an input signal. The input stage includes an input buffer generating an output signal having a logic level based on the voltage of the input signal relative to the voltage of the reference voltage signal. A voltage generator provides a variable output voltage signal that is used as the reference voltage by the input buffer. The voltage of the output voltage signal provided by the voltage generator is dependent on the logic value of the output signal of the input buffer. In this manner, the reference voltage applied to the input buffer can be adjusted based on the logic level of the outputs signal in order to provide increased input signal noise margin.

A gallium nitride layer is laterally grown into a trench in the gallium nitride layer, to thereby form a lateral gallium nitride semiconductor layer. At least one microelectronic device may then be formed in the lateral gallium nitride semiconductor layer. Dislocation defects do not significantly propagate laterally into the lateral gallium nitride semiconductor layer, so that the lateral gallium nitride semiconductor layer is relatively defect free.

A dual input AC/DC power converter (10) having dual inputs (12, 14) adapted to receive both an AC and DC input and provide a selectable DC voltage output (16) and a second DC output (18). The dual input AC/DC power converter (10) comprises a power converter circuit (20) having an AC-to-DC converter (22), a DC-to-DC booster converter (24), a feedback circuit (26), a filter circuit (25) and a DC-to-DC buck converter (28). Advantageously, the power converter (10) resolves many of system management problems associated with carrying all of the different interface components necessary to power a wide variety of mobile products from either an AC or DC power supply. In addition, the power converter (10) also advantageously includes dual output voltage terminals (16/18) to allow for multiple mobile devices of varying power requirements to be powered, simultaneously, by a single converter.

摘要:
A catheter includes a flexible shaft having a lumen arrangement and a length sufficient to access a target vessel of a patient. A balloon at the distal end of the shaft is fluidly coupled to the lumen arrangement. The balloon body comprises a first material and a second material different from the first material. The second material comprises a hydrophilic polymer that becomes electrically conductive in response to absorption of the conductive fluid. The fluid conductive regions facilitate perfusion of the conductive fluid through the balloon body to an inner wall of the target vessel during ablation of perivascular tissues. A cooling arrangement is configured for one of receiving a thermal transfer fluid from the lumen arrangement or facilitating perfusion of blood passing through the target vessel to cool the balloon body during ablation of the perivascular tissues.
摘要:
A shifter that can avoid utilizing a partial pulse, comprising: at least one shifting stage, for receiving an external clock signal or a command triggering clock signal to generate sampling signals according a command signal; and a command triggering clock signal generating circuit, for generating the command triggering clock signal according to the command signal. The shifting stage utilizes the external clock signal to generate the sampling signal but does not utilize the command triggering clock signal to generate the sampling signal, if the command triggering clock signal may have a partial pulse for a cycle that the shifting stage generates the sampling signal.

A flexible catheter includes a magnetically permeable element provided at its distal end. The magnetically permeable element is configured for placement within the renal artery. External coils, positionable on anterior and posterior portions of a patient in proximity to the renal artery, are coupled to a generator which energizes the external coils to create a high-frequency oscillating magnetic field in body tissue between the external coils including the renal artery and perivascular renal nerve tissue. The magnetically permeable element serves to concentrate the magnetic field in a region near the renal artery. The concentrated magnetic field induces high frequency electric current sufficient to ablate the perivascular renal nerve tissue proximate the renal artery. A cooling arrangement can be provided at the catheter's distal end and configured to provide cooling to the renal artery during ablation of the perivascular renal nerve tissue.
