Abstract: A system and method which protects a data processing system against encryption key errors by providing redundant encryption keys stored in different locations, and providing the software with the ability to select an alternate redundant key if there is any possibility that the encryption key being used may be corrupted. In the preferred embodiment, a memory control module in the data processing device is configured to accommodate the storage of multiple (for example up to four or more) independent password/key pairs, and the control module duplicates a password key at the time of creation. The redundant passwords and encryption keys are forced into different memory slots for later retrieval if necessary. The probability of redundant keys being corrupted simultaneously is infinitesimal, so the system and method of the invention ensures that there is always an uncorrupted encryption key available.

Title: Network location and synchronization of peer sensor stations in a wireless geolocation network
Inventor: BULL JEFFREY F
IPC: G01S5/14
Filed: 2011-05-20
Abstract: Transmitters are located with a network of sensors by measuring signal characteristics at multiple known locations and processing these measurements at a central node. The sensors communicate their location to the central node along with measured characteristics of the transmitter's signal, and may be required to synchronize with other sensors. Often, GNSS receivers are utilized to locate and synchronize the sensors. However, the GNSS signals may be attenuated by obstructions. In this case, the sensors determine their location by making ranging measurements with sensors that can receive the GNSS signals. The waveform for the wireless backhaul permits this ranging. Additionally, many sensors can determine their location and time synchronize with the geolocation network through reception of signals from other sensors even if they do not have a direct connection to sensors that know their location and are time synchronized.

Abstract: An assay device includes: a liquid sample zone; a reagent zone downstream and in fluid communication with the sample zone containing a reagent material; a detection zone in fluid communication with the reagent zone. The detection zone includes a substrate and a first set of projections which extend substantially vertically from the substrate. The projections have a height, cross-section and a distance between one another that defines a capillary space between the projections capable of generating capillary flow parallel to the substrate surface. The device further includes a wicking zone in fluid communication with the detection zone having a capacity to receive liquid sample flowing from the detection zone. The wicking zone includes a substrate and a second set of projections which extend substantially vertically from the substrate, and the projections have a height, cross-section and a distance between one another that defines a capillary space between the projections capable of generating capillary flow parallel to the substrate surface. The wicking zone is rectangular in shape and the longer side of the rectangle extends in the direction of flow to thereby reduce the pressure gradient in the assay device which increases the total flow time of liquid sample compared to a wicking zone having equal length sides and same volume. At least a portion of the second set of projections have at least one dimension selected from a diameter, a center-to-center spacing, or a gap between projections that is different from the first set of projections, and is selected to increase the total flow time of the sample through the device.

Title: Axial rotary engine crank assembly
Inventor: GOUDIE RANDY R
IPC: F01B5/00
Filed: 2013-01-23
Abstract: The invention includes an improved more fuel efficient engine design, using a crank disk C.V.  Joint shaft arrangement. This permits pistons and cylinders to be tilted to the side and rotate with the crank shaft assembly, while maintaining crank shaft to cylinder alignment. The head section of the engine contains five small cam shafts driven by a stationary worm gear which turn the cams as they rotate around it, controlling the valves. The cylinder block is cylindrical shaped held in place by two bearings, and rotates with the crank shaft. The exhaust manifold consists of a circular housing bolted to the mounting bracket; two mechanical seals rotate with the cylinder head to eliminate leakage. Variable displacement is achieved by means of a two piece crank case which allows the cylinder to be tilted increasing or decreasing piston stroke. The Variable Displacement Axial Piston Rotary Engine therefore. This invention includes a variable displacement axial piston Rotary engine particularly of the kind commonly known as internal combustion. Background of the Invention Engines have been in use since the early 1800's; with design patents dating back as far. They are in common use in vehicles, aircraft and machinery. They are classed by their features with the conventional being most common. Though engines are very popular, with increasing fuel prices and concern for the environment, improved more fuel efficient engines designs are desirable, and compactness and lightweight are sought after in the small aircraft industry.

Abstract: This invention is a validation process for ipsative assessments. Respondents are connected to an Electroencephalograph (EEG) and some or all of the ipsative assessment questions are asked again while connected to the EEG. The EEG measuring frontal lobe responses in terms of gamma waves is compared with the assessment questions. Positive responses provide one frontal lobe response in terms of gamma waves, negative or false answers provide a different gamma response and neutral questions provide a neutral gamma response. Reading the responses then tells whether the respondent initially responded with integrity, if so the assessment is validated.
