Abstract: The primary objective of the present method and apparatus is to provide a portable and new diagnosis system for quickly and reliably examining tissue conditions. The method uses the most advance miniaturized micro-opto-electro-mechanical systems (MOEMS) for generating a rapid variable optical delay line capable of generating wideband terahertz pulses. The method detects and analyzes cancerous tissues by comparing a plurality of spectrum resolved images of suspected tissue without applying harmful agents into the tissue to facilitate interaction with illumination sources. The method employs non-evasive, real time terahertz imaging systems and techniques to diagnose tissue for detecting the presence of cancer. A map showing, which tissue is healthy and which is cancerous can aid in the accurate removal of cancerous tissue.

Abstract: The objective of the present method and apparatus is to provide a portable diagnosis system for a quick and reliable method to examine the conditions of a human eye-lens. The method provides precise and safe technique for the early diagnosis of Alzheimer's Disease (AD) which is not involved brain surgery or biopsy. The detection of deposited layers of amyloid plaque in the eyes of the patient has been discovered to be a possible diagnosis solution. The disclosed method uses terahertz waves instead of laser for scanning the eye of the AD patient to precisely image the amyloid layer non-evasively in real time and to map the deposited plaque with high resolution which can easily distinguish the abnormality of an AD patient with the comparison of the patient eye-lens test to the available signature of a normal person and the signature of a person with common age-related cataracts.

Abstract: The disclosed method measures the distance between two arbitrary points of interest from the user position by determining the range and angle between the two points. To measure the angle between the two points, a first method uses a micro-opto-electro-mechanical scanner to form a scan line between the two points of interest. A scan angle is determined based on the applied AC voltage needed to cause the endpoints of the scan line to coincide with the points of interest. The second method, an image-processing method, is applied to determine the angles between the points of interest. A Microprocessor uses captured images including the points of interest to determine the angle between the points. In both methods, the Microprocessor calculates the distance between the two points of interest by using the determined angle, together with the measured ranges and sends the calculated distance to a display.

The method provides precise and safe technique for the early diagnosis of Alzheimer's Disease (AD) which is not involved brain surgery or biopsy. The detection of deposited amyloid plaque in the eyes of the patient has been discovered to be a possible diagnosis solution. The disclosed method uses Terahertz waves in both time and frequency domains instead of laser for scanning the eye of the AD patient to precisely image the amyloid layer non-evasively in real time and to map the deposited plaque with high resolution which can easily distinguish the abnormality of an AD patient with the comparison of the patient eye lens test to the available signature of a normal person and the signature of a person with common age-related cataracts.

Abstract: A controlled direct drive engine efficiency uses positive-displacement power produced from a thermal energy source (or sources), which may include combustion energy. Engine power production is from a plurality of cylinders appropriately controlled by a hydraulic drive unit to add to or subtract from such power output to adjust cyclic variations, thus producing a desired velocity profile for a piston (or other mover) in a fluid-displacement cylinder that is being used to effect pumping (or compressing) of liquids, gases, or vapors. The overall system is particularly suited to use a Modified Brayton thermodynamic cycle where the power output is delivered through a common rod to a positive displacement fluid pumping or compressing device. Interconnected with that common rod is a double-acting hydraulic cylinder which is operated in conjunction with a rotary, variable volume hydraulic motor/pump to effect the desired adjustment.

Abstract: An advanced imaging spectrograph system and method are provided for very high throughput identification, sequencing and/or genotyping of DNA and other molecules. The system is based on the integration of improved electrophoresis structures with an imaging spectrophotometer that records the entire emission spectra along an imaging line across a sequencing gel (or capillary array). The system includes spectral shape matching to improve dye identification allowing the use of dyes having nearly any emission spectra and allowing greater than four dye multiplexing.

Abstract: An energy-recovery pump or pumping system includes, in a double action embodiment, first and second cylinders wherein respective first and second pistons, mounted to a common reciprocating piston shaft, are mounted for reciprocating motion. A hydraulic pump drives the common piston shaft back and forth in accordance with a prescribed velocity profile that includes acceleration, constant velocity, and deceleration periods, as well as a short dwell time at the conclusion of each stroke during which the shaft and pistons remain stopped. Each piston divides each cylinder into first and second working volumes. Input and output valves connect a source of fluid with an output header through half of the working volumes in such a way that the fluid is received within whichever working volume is expanding and is pumped from whichever working volume is contracting, as the pistons move back and forth within their respective cylinders during a pump cycle.
