Abstract: A system and method for selecting redundant rows and columns of memory devices includes a column select steering circuit to couple column select signals from a column address decoder to an array of memory cells. The system and method also includes a fuse banks for programming respective addresses of up to two defective columns that are to be repaired. The programmed addresses are applied to a defective column decoder that determines which column select signal(s) should be shifted downwardly and which column select signal(s) should be shifted upwardly. The column select steering circuit responds to signals from the defective column decoder to shift the column select signals downwardly or upwardly. The column select signal for the lowest column is shifted downwardly to a redundant column, and the column select signal for the highest column is shifted upwardly to a redundant column.

Abstract: A device for locating a puncture hole in a liquid-carrying vessel such as a blood vessel comprises a hollow tube 92 having front and rear openings respectively at opposite ends of the tube to allow the tube to slide along a guidewire passing through the tube. The front opening 96 comprises a first portion 96A for slidably accommodating the guidewire and a second portion 96B to allow liquid from the vessel to flow back through the tube. The device is configured, e.g. by a constriction 96C, such that a guidewire at least above a certain diameter in the first portion 96A of the front opening is restrained against moving into the second portion 96B. Alternatively, the first and second portions 96A, 96B of the front opening may be independent of one another.

Abstract: A surgical stapler comprises a hollow shaft 10 and a tube 92 slidable axially within the shaft between a forward position wherein one end 96 of the tube projects beyond a free end of the shaft to enter a puncture site in a blood vessel and a rearward position wherein the end of the locator tube is retracted within the shaft. A surgical staple 40 straddles the tube 92 and is slidable thereon forwardly towards an anvil 24 against which the staple may be deformed to staple together the opposite edges of the puncture site. A cam mechanism drives the staple forwardly along the tube 92 into deforming engagement with the anvil and at the same time retracts the tube into the shaft in time to allow the legs of the staple to close onto the puncture site.

Abstract: A surgical staple is provided having a base portion and a respective leg extending from each end of the base portion and terminating at a free end. The base portion is deformable to bring the free ends of the legs together to penetrate a liquid-carrying vessel at the site of a puncture and hold the opposite edges of the puncture together. The base portion and legs lie in substantially a common plane except for a center portion (40C) of the base portion which is deformed in a loop in a direction perpendicular to the common plane. The center portion of the staple allows the staple to straddle a blood locator tube projecting from the end of a stapler, so that the staple can be closed at the center of a puncture wound in which the tube is located. A method for stapling is also provided.

Abstract: The invention relates to a dispensing machine for printed publications. The vending machine allows to dispense one copy at a time by providing a metering break next to a dispensing channel. The vending machine has a hollow housing, within which a detachable module is slidably mounted. An operational portion of the machine includes a motor controlled by a microchip that constantly adjusts the speed of the motor depending on the thickness of the dispensed publication. A paper speed sensor sends a signal to the motor to facilitate adjustment in the speed control. Printed publications rest in an upright position on moving endless belts that are connected to the motor for advancing the publications toward the dispensing channel. One or more torsion springs support the front face of the forwardmost publication immediately prior to dispensing to prevent premature opening of an unfolded edge of the publication and jamming of the dispensing channel.

The procedures comprise decapitating an invertebrate, in the disclosed tests a Drosophila melanogaster is used. A selected neuroactive agent is applied directly to the severed nerve cord of the invertebrate. The reaction of the invertebrate is observed in response to the application of the agent. The reaction of the invertebrate is an indication of the activities of the cellular receptors which react to the specific agents. The tested agents include dopamine, serotonin and octopamine and vertebrate drugs that act as D1-like receptor agonists, D1-like receptor antagonists, D2-like receptor agonists and D2-like receptor antagonist, and a vertebrate monoamine oxidase inhibitor. Other types of neuroactive agents are also used.

Abstract: A broadband spectrum analyzer for radio frequency and microwave signals. The signal to be analyzed modulates an optical laser beam through an electro-optic modulator. The resultant modulated beam thus comprises light at a frequency (carrier frequency) corresponding to the wavelength of the laser beam and frequencies close to the carrier frequency corresponding to the frequencies representing the modulating signal. The modulated beam is expanded to produce a beam with light traveling in a large number of directions within a narrow angle. The expanded beam illuminates the aperture of an etalon. The etalon functions as an optical filter passing only portions of the beam which enter the etalon at an angle such that the distance traveled by the light within the etalon equals an integral number of wavelengths. Thus, different frequencies pass through the etalon at different angles. The output from the etalon is collected by a video camera for display and interpretation.

Abstract: A camera system in which microwave radiation from objects in a field-of-view is collected by an antenna having beam directions which are a function of the beam frequency. The collected radiation is used to modulate an optical beam to impose upon the beam spectral components which are functions of the frequencies of the microwave radiation. The modulated beam is then analyzed by an optical spectrum analyzer to produce an image of objects in the field of view. In a simple embodiment of the invention a one dimensional image is produced. This one dimensional image can be converted to a two dimensional image by panning the camera system or mounting the camera on a moving platform. In this preferred embodiment the spectrum analyzer comprises an angle-frequency filter (preferably an etalon). The portion of the modulated beam passing through the etalon is directed in a number of directions, the directions being a function of the spectral components of the modulated beam.
