Abstract: A method of encrypting a data stream includes receiving the data stream, and for each data packet in the data stream, forming an encrypted packet by encrypting a header portion of the data packet while leaving a body portion of the data packet unencrypted. The method also includes assembling an encrypted data stream comprising all the encrypted packets, and outputting the encrypted data stream.

Abstract: A radio headset device provided for receiving and reproducing a radio broadcast from a radio device in a high noise environment. The radio headset device comprises left and right earcups, a speaker mounted to each of the earcups, and a microphone mounted to each of the earcups for converting acoustic noise outside the earcup into a corresponding electric noise signal. The radio headset device further comprises a noise cancellation module electrically connected to the microphones and the speakers, and a radio connector provided on one of the left and right earcups for selectively electrically connecting the radio headset device to a radio device. The noise cancellation module receives the electric noise signal from the microphones and generates a noise cancellation signal acoustically reproduced by the speakers.

Abstract: The present invention relates to a method for developing algorithms that are capable of discriminating among different genotypes and subtypes of a virus of interest. The method includes aligning a set of viral nucleotide sequences having known genotypes and analyzing the aligned sequences to identify nucleotide positions at which the nucleotide is conserved within genotypes, but diversified across the different known genotypes. These positions, referred to herein as genotyping positions, are employed as predictive variables to compile a variable input table for analysis by a statistical classification algorithm. The variable input table also includes the nucleotide present at each genotyping position as a value and the genotype for each of the aligned sequences as a response variable.

Abstract: A lighting system adapted to mount on a motorcycle or bicycle helmet. The lighting system includes one or more accelerometers coupled to the helmet and a processor adapted to process the signals from the accelerometers. The accelerometers may be mounted to the helmet, or to the motorcycle or bicycle. The lighting system further includes a light mounted on the helmet that is responsive to the processed signal such that the light illuminates as result of a deceleration force. The system may also include filtering software to remove helmet motion artifact and other noise from the signal. Remote wheel speed indicators may also be used in conjunction with or in place of the accelerometers. Mounting tabs may also be included to releasably attach the lighting unit to the helmet.

Abstract: The use of an iontophoresis electrode assembly for delivery of a drug formulation is described. The drug formulation includes an anaesthetic and a vasoconstrictor. It is administered to a patient prior to a procedure to produce clinically acceptable depth and duration of dermal anaesthesia at the portion of skin to subject to a painful procedure or to reduce or eliminate pain. The procedure is one selected from the group consisting of venipuncture, IV cannulation, needle aspirations, body piercings, blood donations, electrolysis, tattoo removal, tattoo application, injections, dermabrasion, skin peeling, high velocity particle ablation, pace maker implantation, pace maker replacement, epidural puncture, lumbar puncture, regional nerve blocks, skin harvesting, small skin incisions, skin biopsies, circumcisions or excisions. The iontophoresis electrode assembly may also be used to reduce or temporarily eliminate neuropathic pain.

Abstract: A method and system are provided for programming a plurality of memory devices arranged in parallel. In one embodiment of the present invention, the plurality of memory devices comprises first and second memory devices, and the method comprises providing successively the first address to the first memory device and the second address to the second memory device. The first address refers to a first group of storage locations in the first memory device and the second address refers to a second group of storage locations in the second memory device. The method then proceeds to load in parallel a string of data to the first and second memory devices so that the string of data is written simultaneously to the first group of storage locations in the first memory device and to the second group of storage locations in the second memory device.

Abstract: The present invention provides a systems, methods, and products for enhanced user navigation to compliment (but not necessarily replace) a computer keyboard and mouse by providing a robust navigation interface. The present invention may comprise: a minimally necessary group of commands; combining the functionality a set of at least two command calls into a single logical button; for a single button, prioritizing a set of command calls from first to last and then calling each until one is accepted; logically remapping commands to buttons for a navigational device coupled to a physically rotate-able display device; and mapping a substitute command to a logical button for when the button is engaged in a predetermined manner other than the primary manner in which the logical button is engaged (e.g., double-clicking, flicking, press-and-hold, etc.) so that a substitute command can in fact be issued, among others.

Abstract: A system for encoding and decoding information of a codeblock from a memory buffer that includes a context modeler that receives from the memory buffer the codeblock and divides the codeblock into a plurality of codesegments or decodes a codeblock worth of information from received compressed data. The codesegments includes a plurality of bits. The context modeler processes each of the codesegments individually by determining whether any of the bits need special coding information or decoding. The context modeler outputs coded bits associated with the bits that are coded with the special coding information and context information associated with the coded bits or outputs a codeblock worth of information to the memory buffer. An arithmetic coder receives the context information and coded bits and compresses the coded bits or receives compressed data and decompresses the compressed data to produce context information and coded bits.

Abstract: A video compression circuit comprises an input that receives an input video signal. A memory buffer, coupled to the input, temporarily stores a portion of the input video signal. A single horizontal filter bank, coupled to the memory buffer, high-pass and low-pass filters horizontal components of the input video signal. A single vertical filter bank, also coupled to the memory buffer, high-pass and low-pass filters vertical components of the input video signal. A recursion buffer, coupled to the filter banks, temporarily stores filter components of the input video signal for recursive filtering.

Abstract: This invention relates to an improved assay device and assay for detecting or quantitating the presence or absence of a substance in a sample. The device has multiple layers comprising a permeable layer (a) having a capture reagent attached to less than the entire membrane, a selectively permeable layer (b) which does not allow assay reagents to pass through (b) and an absorbent layer (c). Layer (b) is in communication with layers (a) and (c). Layer (b) has at least one hole extending therethrough and the hole or holes are directly below the capture reagent in layer (a). The area of the hole or the combined area of the holes is less than the area covered by the capture reagent.

Abstract: An automatic drive hammer system includes an automatic drive hammer apparatus which is carried by a bucket pivotally mounted to a drill rig. The drive hammer apparatus may be pivoted in the bucket from an off-hole storage position to an on-hole loading/unloading position whereby the drive hammer apparatus is lifted out of the bucket by a winch assembly and the bucket is pivoted to the off-hole storage position. An anvil and connector connects to a drill string and sampler which extend upwardly from a hole in the ground. The drive hammer apparatus has a housing which contains a hammer adapted for reciprocal sliding movement therewithin to cyclically strike the anvil to drive the anvil, drill string and sampler combination into the ground. A trip rail is rigidly attached to the anvil and extends within the housing. A follower assembly is pivotally mounted to the hammer.
