Abstract: Applicant has disclosed an x-ray fluoroscopy machine made substantially entirely of parts which cannot be magnetized. By making the machine out of parts which cannot be magnetized, the x-ray machine can be placed in the same room as an MM machine without the fluoroscope affecting the magnetic field of the MRI machine. Both machines therefore are capable of operating (e.g., imaging) simultaneously in the same examination room. In the preferred embodiment, Applicant has disclosed making a mobile C-arm device, disclosed in U.S. Pat. No. 7,300,205, substantially out of materials which cannot be magnetized.

Abstract: Applicant has disclosed a method and apparatus for a bipolar automotive electrical system. In the preferred “apparatus” embodiment, Applicant's bipolar electrical system comprises: two (e.g., 12 V) batteries of equal, but opposite voltage (e.g., +12 V, ?12 V), with bipolar outputs; an alternator, responsive to the batteries, which controls electrical charge to the batteries individually; an automotive DC motor connected by a single lead wire to the bipolar outputs from the batteries; and, wherein the reversible motor is run off the bipolar output without the need for any intervening devices between the bipolar command outputs and the motors. Alternatively, the alternator can inherently charge the batteries sequentially with the lowest voltage battery being addressed first. This approach allows heavy loads to be powered by 24 V or 48 V DC, yet the arc voltage to ground is still only 12 V or 24 V DC.

Abstract: Applicant has disclosed an improved method and apparatus for installing electrical junction boxes in embedded concrete construction applications. In the preferred embodiment, a first box (with at least one attached conduit) is embedded in the bottom of a concrete deck at pour, wherein the box has an open bottom covered during the pour. After pouring, the cover is removed to expose the open bottom, through a plane of the deck, without having to break through the concrete. A second box, with an open top, is lifted up and fastened (preferably, screwed) to the embedded first box to complete a preferred electrical junction box. The second box is designed to be exposed to accept surface mount or exposed wiring methods. There is a passage between the first and second boxes for accepting wire pulled through the conduit(s).

Abstract: Applicant has disclosed a method for controlling on and off times for streetlights by synchronizing these intervals to recent local daylight conditions without any human intervention. The preferred method comprises: sensing, via a photocell, when dusk and dawn occurs; and then, timing or counting the dusk and dawn times per 24-hour cycle, recording that dusk and dawn data, calculating the average dusk-to-dawn interval for a plurality of preceding 24-hour cycles; predicting, the next dusk time; and turning on the streetlight for a preselected percentage of the calculated average dusk-to-dawn interval. Future “on” time periods are repeatedly calculated as a percentage of the dark periods determined on one or several immediately prior nights, and so varies with the seasons. Unlike the prior art, Applicant's streetlight control does not require field programming or field inputs from the installer or time knowledge. It also does not require any external or internal precision clock or calendar.

Abstract: Applicant has disclosed a method for removing motion from non-CT cardiac angiographic or fluoroscopic x-ray 2-D sequential images, without using data prediction techniques in sequential CT imagery. Applicant's results are achieved by actively deleting or skipping exposure of certain 2-D flash image acquisitions during rapid heart motion (e.g., beating), the latter to reduce x-ray exposure. Applicant's preferred method comprises: positioning a person relative to a non-CT type x-ray machine, designed for fluoroscopy or angiography, with the person's heart between an x-ray source and a detector; monitoring rapid movement of the person's heart by electrocardiography; generating a series of x-ray pulses from the x-ray source; actively skipping any x-ray pulses by switching off the x-ray source during beating of the person's heart to prevent any images being generated from the skipped x-ray pulses; and generating sequential (i.e.

In the preferred embodiment, the improved ignition system comprises at least two secondary ignition coils wired in a high voltage “OR” configuration using a single high voltage circuit through a distributor, or alternatively a single plug operated directly from diodes connected respectively to associated secondary coils. The ignition coils are set up to alternate sparks, so that even at 8000 engine RPM, each coil is firing as if operating at 4000 RPM, a speed where conventional highly optimized and inexpensive coils are very effective and can reach their full output.

Abstract: An improved rotating anode x-ray tube housing is disclosed. In the preferred embodiment: a single cable, insulated with Ethylene-Propylene Rubber (“EPR”), has an extended Federal Standard terminal or plug mounted within an extended Federal Standard receptacle, attached to an anode end of the housing; the cable is designed to carry up to approximately 150 kV to power the cathode; and insulation of the plug also insulates the 150 kV from a grounded center portion of the x-ray tube and the anode disk area. The longitudinal axes of the anode and high-voltage plug are parallel to one another. This new configuration allows the cathode plug and receptacle to be moved virtually entirely inside the housing. This results in absolute minimal size of the assembly, and a single cable that exits parallel to the rotational axis of the housing.
