Abstract: A method and apparatus annotates a computer program to facilitate subsequent processing of the program. Code representing the program is generated at a first computer system. Annotations are generated for the code that provide information about the code. At a second computer, the code is processed according to the information provided by the annotations. The annotations, for example, can indicate a control flow graph representing a flow of execution of the code. Also, the information provided by the annotations can be a register allocation that maps data structures of the code to registers of the second computer system. The second computer system can use such information to guide the interpreting of the code or to transform the code into a more optimized form. Other exemplary annotations can indicate that running the executable form of the code would perform an unauthorized operation at the second computer system.

Abstract: An implantable single or dual-lumen or more lumen device for repeated accessing vessels within a body. The device uses a resilient material to form a seal, and has a smooth streamlined flowpath with no flow discontinuity. The device is joined to a catheter, in most cases, such that fluids can be extracted from or injected into the vessel to be accessed. The device is designed for the high flowrates, on the order of 150 and greater milliliters per minute, associated with hemodialysis, plasmapheresis, and other fluid exchange therapies. In such applications smooth flow streaming is important to minimize damage to the blood. A corresponding straight-needle apparatus is designed to mate and lock with the access device, where alignment and open flowpath is ensured. A valve seal incorporates opposing very hard surfaced guide elements that are retained and in intimate contact with the seal itself.

Abstract: A spring loaded or mechanically activated detent for a microphone stand that allows for quick disassembly and re-assembly. The microphone main shaft (102) is terminated at the lower end with a circumferential raceway or slot (44). The base has a coaxial matching cavity that accepts the lower end of the microphone shaft. At a depth to match the raceway, a spring loaded ram, positioned radially, extends into and mates with the raceway to secure the shaft to the base. In another preferred embodiment a spring clip or a stiff clip can be mechanically inserted through a radially extended opening in the base to engage the slot in the lower end of the shaft. There may be other such rams distributed around the circumference of the shaft. In another preferred embodiment the raceway may extend only partially around the circumference of the shaft. The raceway will be of a uniform depth for some arc length ending with a lip and a ramp up to the surface.

Abstract: A device for automatic dilution of chemical additives and water utilizing a single pump (20) drawing water and other chemical additives through a dilution manifold (10). The introduction of air into the system is monitored such that the system performance is not impaired. If the air leak is small corrections can be made or the system will accept the small error, but if the air leak is large, the system will shut down and activate an indication or alarm to signify that some malfunction has occurred, such as a chemical supply being unconnected or empty.

Abstract: A dual-lumen catheter is disclosed that allows access to the vascular system of humans or animals for the high volume fluid flow related to hemodialysis or therapeutic apheresis. One lumen is circular with a wall thickness and material such that the lumen remains open during the fluid exchange. The second lumen is relatively thin walled designed to collapse against the first lumen under the pressure associated with the vascular system. This collapsing provide a minimum cross section of the catheter as it enters the body and the vascular system. However, the second lumen opens under pressure as a high volume fluid flow is introduced into the vascular system through the second lumen. This high volume fluid flow into the body is most often a return of fluid removed from the body via the thicker walled lumen.

Abstract: A method of improving the performance of a traveling wave field-effect transistor operated at frequencies in the microwave range or above the microwave range comprising the steps of forming a depletion region beneath a gate electrode wherein, in a plane transverse to the direction of signal propagation, a depletion region edge has a first end portion located between the gate electrode and a drain electrode and a second end portion located between the gate electrode and a source electrode; and separating the depletion region edge from the drain electrode. Further improvements in the operation of the TWFET include adjusting the first end portion of the depletion region edge to be closer to the gate electrode relative to the distance between the second end portion of the depletion region edge and the gate electrode, controlling an effective conductivity of a semiconductor of the traveling-wave field effect transistor, and setting the length of the gate electode at about one micron.

Abstract: A method and apparatus for encoding and compressing a text word of ASCII code by substituting a binary number for said word and sending, storing or recording said binary number. The binary number is retrieved and replaced by the original text word. The binary representation of the word may be placed in a digital real time IRIG, preferably IRIG-B, frame wherein the text word is time stamped so as to record the actual time when the text word was placed in the time frame. The text word may be initially generated by a typist, or by a voice to text machine vocabularies of words to be encoded by replacement with the binary number are formed, and the encoding or encrypting vocabulary may be different from the decoding or decrypting vocabulary. The differences may include foreign languages or combinations of languages. Additional encryption may be obtained by forming a offset in the binary number for the first and the subsequent words used in each vocabulary.

Abstract: An electrical connector for joining individual, electrically conductive wires, to a printed circuit board. The wires may be individual solid or stranded types. A contact, provided within the connector housing, is arranged with a first end forming an area for attaching the wire and with a second end arranged usually with female contacts for connecting to a header on the printed circuit board. The wires are stripped of any insulation and mechanically attached to a contact in the connector. The wire is placed between a pressure plate and an area of the contact. A screw is rotated forcing the pressure plate and the contact area together physically squeezing the wire so that the wire is securely attached to the contact area to provide a good electrical contact. The second end of the contacts forms a female cantilevered contact arranged to mate with a header of a row of male pins soldered to the printed circuit board.

Abstract: An encryption/decryption apparatus that provides at least two masks, each of which is used in logic/mathematic operation with information to be encrypted to preserve confidentiality. The operations include exclusive oring, addition, subtraction. The source of the masks can be any commonly found data, for example, the code of a music CD. In such a manner the sender may tell the receiver in private that the masks are from a particular track on a particular CD, sampled in a particular fashion, using a particular password. The product of the number of elements in each mask need not be greater or equal to the number of elements in the data file being encrypted. Repetition may make the decoding easier for an eavesdropper, but the use of a password character array to control the use and sequencing of each set of encoding mask operations greatly helps in maintaining the confidentiality of the data. The present invention includes use as a one-time-pad and can be implemented on personal computers.

Abstract: A socket for a ball grid array integrated circuit package (BGA) with an array of electrical contacts (*12) that extend through holes in a slidable plate. The arrangement of spacing the holes (14) and the electrical contacts therein provide entry openings that allow the ball contacts (16) of a BGA package to enter the openings. The contacts are cupped or angled to mate with the side and top of the ball contacts of the ball grid array package. The contact surface of the ball grid array package is vertically inserted into the socket without any interfering structure, and there are guide surfaces to align the ball contacts with the openings. The plate (3) is driven parallel to the plane of the ball contacts in a manner that reduces the entry hole opening by means of a rotating cam placed at one end rotated by a torsion spring.
