摘要： A pulse generator utilizes a pair of current sources acting through a pair of Schottky diode switches to provide load currents in opposite directions through a load resistor to produce an output voltage across the load resistor of magnitude proportional to the difference between the load current magnitudes. The pulse generator output voltage is abruptly driven to zero potential by applying balanced, rapid slewing voltage pulses to the Schottky diode switches, causing the switches to simultaneously divert the load currents from the load resistor. The balanced voltage pulses are developed at the terminals of a step-recovery diode by switching the step-recovery diode from forward to reverse bias state.
摘要翻译：脉冲发生器利用通过一对肖特基二极管开关作用的一对电流源，通过负载电阻器在相反方向提供负载电流，以在负载电阻器两端产生与负载电流幅度之差成比例的大小的输出电压。通过将平衡的快速回转电压脉冲施加到肖特基二极管开关，使脉冲发生器输出电压突然驱动到零电位，使开关同时转移负载电阻的负载电流。通过将升压二极管从正向切换到反向偏置状态，平衡电压脉冲在阶跃恢复二极管的端子处产生。

摘要： A dual channel time domain reflectometer includes a pair of input lines connected at respective nodes to a reference flat current pulse generator and a traveling wave sampling gate, respectively. The sampling gates are actuated by a balanced strobe generator which includes a waveguide coupler for coupling a high amplitude fast rise time pulse to each of the gates simultaneously. Pulses of requisite amplitude and shape are generated by a circuit responsive to a strobe trigger input which drives a step recovery diode.

摘要： A method of producing of a two-dimensional probability density function eye diagram and Bit Error Rate eye arrays generates a two-dimensional PDF array of a correlated waveform record of a data pattern under test which is convolved with a two-dimensional probability density function (PDF) array of the uncorrelated jitter and noise in the data pattern under test. The resulting aggregate two dimensional PDF array of the correlated waveform record pattern with uncorrelated jitter and noise is divided into unit intervals and the unit intervals are summed to generated a two-dimensional PDF eye diagram array. The two-dimensional PDF eye diagram is processed to generate a two-dimensional Bit Error Rate eye array.

摘要： Systems, kits, and methods for establishing vascular access are described. A system may include a needle, a radially expandable sleeve and a dilator. The methods include creating an initial tissue tract to a target blood vessel with a radially expandable sleeve mounted on a needle. Upon removal of the needle, the dilator is then passed through the radially expandable sleeve to effect radial expansion of the sleeve. Use of the sleeve reduces the risk of injuring tissue surrounding the tissue tract by lessening the axial forces imparted to the tissue. Kits comprise at least the radially expandable sleeve together with instructions for use.

摘要： An apparatus and method for forming and enlarging percutaneous penetrations comprises an elongate dilation member which receives an elongate expansion member in an axial lumen thereof. The dilation tube includes a tubular braid which usually comprises a mesh of non-elastic filaments which are radially expandable from a small diameter configuration to a large diameter configuration and which is optionally covered by a removable sheath. The dilation tube is percutaneously introduced to a target site within a patient's body, usually within the abdomen in a laparoscopic procedure. The sheath (if present) is then removed, and the tubular braid thereafter radially expanded by axial insertion of the expansion member through its lumen. The tubular braid is anchored by axial shortening of the mesh and remains in place to permit subsequent exchange of dilation members to provide for different diameter access lumens. Trocar valves may be removably attached to the proximal end of the expansion member to permit the apparatus to be used as a trocar system in laparoscopic procedures where the patient's abdomen has been insufflated. An anchoring means may optionally be provided at the distal end of the expansion member.

摘要： An access system comprises a radially expandable sleeve, a pneumoperitoneum needle, a cannula assembly, and an obturator. Methods for reconstructing and reusing the access system comprise replacing the radially expandable sleeve and cannula valve cap components of the system, both of which are disposable. All remaining system components may be sterilized and reused one or more times. The pneumoperitoneum needle can be separated into tubular needle body and needle stylet components, which may be separately replaced or sterilized and reused. Similarly the cannula comprises both a cannula hub and a cannula tube, where the hub and tube may be separately replaced or sterilized.

摘要： A step generator for producing steps having constant edge parameters while driving varying loads includes a pair of DC coupled low speed diode switches for slowly switching the output load current. A pair of capacitors provide an AC coupled high speed input for rapidly, but temporarily, switching the output load current until the sustaining action of the low speed diode switch has occurred. A pair of resistor divider circuits in each of the low speed diode switches maintains a relatively constant reverse bias voltage across the diodes coupled to the capacitors. The high speed switching threshold is maintained at a relatively constant level which produces an output voltage step with constant edge parameters and no overshoot.

摘要： Using a buffered acid catalyst, a cross-linked urea-formaldehyde polymer matrix is formed by catalyzing an aqueous mixture of an urea-formaldehyde concentrate, urea-formaldehyde resin, and powdered urea. The resulting thermoset polymer which possesses, in part, a cyclic structure, is of unusual hardness and has utility, with or without fillers, as a molding or casting material possessing controllable shrinkage characteristics because of uniform molecular structure and formula versatility. The catalyst system may be used for the polymerization or cure of other urea-formaldehyde or polymeric condensation systems.

摘要： A camera system and method provide a trailing motion blur effect without the use of a flash. In one embodiment, a variable light-transmissive filter is positioned in front of an image sensor. While the light-transmissive property of the filter is lower, the blurred image of the object in motion is produced. The light-transmissive property of the filter is increased during the exposure in order to produce a clearer image of the object. In a method, a plurality of images taken in rapid succession are combined to produce a clear image of the object with a trailing blurred image of the object.
