Title: Method and apparatus for the automatic analysis of computer software
Inventor: SHAPIRO BENJAMIN V
IPC: G06F11/28
Filed: 1994-05-10
Granted: 2000-08-01
Abstract: A method and apparatus for the analysis of a computer process is disclosed. The method consists of the steps of analyzing a target process and constructing a model and repository which are representative of the control and non-control components contained within the original target process respectively. The resultant model and repository are executed, and their execution is representative of the original target process.      Structures created during the execution of the model and repository assist a user to identify failures which occur during the execution, and then locate the fault(s) responsible for the failures as well as places within the target source where modifications due to new requirements are needed. An alternative form of object code is proposed which consists of two components, control and non-control components. Previously described model representing the control component constantly increases the intelligence of the resulting object code in respect to the target process being executed through the processes of propagation of elementary knowledge about the correctness or uncertainty of the target process elements execution.

Abstract: Several genes encoding subunits of the neuronal nicotinic acetylcholine receptors have been cloned and regulatory elements involved in the transcription of the .alpha.:2 and .alpha.:7-subunit genes have been described. Yet, the detailed mechanisms governing the neuron-specific transcription and the spatio-temporal expression pattern of these genes remain largely uninvestigated. The .beta.2-subunit is the most widely expressed neuronal nicotinic receptors subunit in the nervous system. We have studied the structural and regulatory properties of the 5' sequence of this gene. A fragment of 1163 bp of upstream sequence is sufficient to drive the cell-specific transcription of a reporter gene in both transient transfection assays and in transgenic mice. Deletion analysis and site-directed mutagenesis of this promoter reveal two negative and one positive element. The positively acting sequence includes one functional E-box. One of the repressor elements is located in the transcribed region and is the NRSE/RE1 sequence already described in promoters of neuronal genes.

Title: Selectively cleavable linkers based on iminodiacetic acid ester bonds
Inventor: LEBL MICHAL
IPC: C07K5/00
Filed: 1994-06-21
Granted: 2007-04-03
Abstract: The present invention is directed to linkers based on ester bond linkages, especially iminodiacetic acid ester bond linkages, for use in solid phase peptide synthesis. In particular, the invention is directed to cleavable linkers that can release peptide from the solid phase support under relatively mild conditions by formation of a diketopiperazine or other cyclic structure, such that the cyclic structure remains on the solid phase support, and, in a second cleavage, under mole stringent conditions of high pH. The invention is further directed to solid phase supports prepared with multiple cleavable linkers, including a linker that is cleaved by formation of a cyclic product. One such second linker is an ester of hydroxymethylbenzoic acid, or esters formed by carboxy groups of aspartic or glutamic acid.

Abstract: A mechanism for clamping a banjo toolrest or toolrest bracket to a lathe bed which makes use of a sliding cam which is actuated by a drive shaft. The cam is supported independently of the drive shaft by a support block resting on a ledge which is formed in the base of the banjo. The cam is slidable with respect to the drive shaft along the length of this ledge on the banjo. This structure allows for sturdy clamping with minimal deflection at a predicable catching position along the length of the banjo rest. An eye bolt is used to connect the cam to a clamping plate which is positioned below two, spaced-apart rails extending along the top of the lathe bed. The banjo rest has a generally open bottom through which the shank of the eye bolt extends. Opposite ends of the drive shaft are rotatably supported by end walls of the banjo rest.

Abstract: A scalpel blade remover (3) removes a blade (5) from the tang (6) of a scalpel (8). The scalpel (8) is inserted in, and withdrawn from, the blade remover (3) along the same substantially straight- line path. The blade remover has a rocker block (12) which pivots about an axis transverse to the insertion path. When the scalpel (8) is inserted into the blade remover, its tang (6) pushes against a contact surface (15) of the rocker block (12), causing the block to pivot. A pair of legs (14) at the other end of the block (12) apply a transverse force to the heel of the blade (5) on either side of the tang (6), thereby lifting the heel of the blade off the tang. When the scalpel has been inserted far enough, a pawl (16) drops behind the heel of the blade (5). The pawl strips the blade (5) from the tang (6) when the scalpel handle (8) is removed. The blade remover (3) is typically mounted in the lid (2) of a shar ps container (1).

Abstract: There is provided an improved method for making synthetic hydrotalcite by first reacting powdered magnesium oxide with a high surface area, transition alumina in a solution or suspension to form a meixnerite-like intermediate. This intermediate is then contacted with an anion source such as an acid, and most preferably carbon dioxide, to form the layered double hydroxide which is separated from the suspension by filtering, centrifugation, vacuum dehydration or other known means. On a preferred basis, the transition alumina combined with activated magnesia consists essentially of a rehydratable alumina powder having a surface area of 100 m2/g or greater. To make related double hydroxide compounds, still other reactants such as bromides, chlorides, boric acids, or salts thereof, may be subsituted for the carbon dioxide gas fed into this suspension.

Abstract: An optical repeater is described which integrates an erbium doped optical fiber amplifier (EDFA) with a dispersion equalizer (DE) based on fiber gratings. The dispersion equalizer is based on parallel connection of two fiber gratings for single carrier wavelength operation, and on parallel connection of a cascade of two fibre grating branches, each carrying a plurality grating elements chirped for different wavelengths, for WDM operation at a plurality of wavelengths.      The use of two gratings sections for each wavelength improves the optical bandwidth of the equalizer compared with single grating designs, doubling the effective bandwidth. Further, the grating DE is disposed between two fiber amplifier sections which share a single pump laser. Thus, this arrangement provides dispersion compensation and loss compensation in an optical repeater of lower cost, and smaller size, compared to a system of similar performance configured using discrete components.

Granted: 2005-09-20
Abstract: A method and apparatus for producing a transition-controlled, DC-balanced sequence of characters from an input sequence of data bytes is disclosed herein. The bits in each of the data bytes are selectively complemented in accordance with the number of logical transitions in each data byte in order to produce selectively complemented data blocks. A  cumulative disparity is then determined between the logical values of different type included within ones of the selectively complemented data blocks previously encoded into characters. In addition, a current disparity in a candidate character associated with a current one of the selectively complemented data blocks being encoded is also determined. The candidate character is assigned to the current one of the selectively complemented data blocks if the current disparity is of a polarity opposite to a first polarity of the cumulative disparity.  Alternately, the complement of the candidate character is assigned to the current one of the selectively complemented data blocks if the current disparity is of the first polarity. In a high-transition mode of operation, the bits within data blocks including less than a minimum number of logical transitions are selectively complemented so that each such selectively complemented data block includes in excess of the minimum number of logical transitions. In a low-transition mode of operation, the bits within data blocks having more than a predefined number of logical transitions are selectively complemented so that each such selectively complemented data block includes less than the maximum number of logical transitions.
