Abstract: Breast cancer patients are treated intraoperatively with radiation shortly after excision of a tumor. Pathology of the tissue is determined with a nearly instantaneous method, further excision is performed if needed, and the patient, still anesthetized and preferably unmoved, is then treated with radiation therapy. In a preferred embodiment an applicator is inserted into the excision cavity, the cavity is three-dimensionally mapped using radiation sources and a sensor, a radiation treatment plan is developed using a radiation prescription and the determined shape and location of the cavity, and the treatment plan is executed, all while the patient remains under anesthesia.

Abstract: An electronic identification tag, usually in very small size, responds to a reader with an identification code unique to the object to which the tag is attached. The stand-alone device responds to a reader signal by storing energy received from the signal, then using the stored energy to generate another signal that is encoded with identification information. In operation, a reader generates RF energy which can reach a multiplicity of such tags over a distance of several meters. The system minimizes power requirements for the tag by minimizing intelligence in the IC. Use of a transmit frequency which is different from the reader's power frequency reduces interference between the power pulse and information pulse, eliminates the need for filters and enables the multiplied clock reference frequency as the transmit carrier frequency.

Abstract: An exercising system has a frame defining a space in which a user is positioned for performing a large number of different exercises. Frame members have holes within which flexible bars are positioned, spanning across the machine, for low-impact exercising using the bars. In a preferred embodiment the bar-supporting frame members, or some of them, are adjustable in position so as to provide a nearly unlimited number of positions for different users and for different exercises. A few of the many exercises facilitated by the system are described.

Abstract: An apparatus and method for efficiently generating a visible line of light on a surface such as a wall or a floor for the purpose of facilitating the layout process used in construction. Reference marking elements on the instrument correspond to the light beam's position. One or more level vials may be included for indicating vertical and horizontal, as well as a magnet for mounting and a reference bracket for a stud-finder instrument. In one embodiment the instrument is self-leveling on one axis only and is useful for projecting one or more orthogonal lines on a wall surface. The instrument, self-leveling or not, can be combined with a stud finder.

Abstract: A conveyor chain for poultry processing is formed of injection molded regular links in serially connected relationship, and has at intervals a special link adapted to receive a threaded stud for a chicken carcass-supporting cone or other structure. The special link has a base portion which is of preferably the same configuration as the regular links. Above this, integrally molded with the base portion, is a platform with laterally outwardly extending flanges for stability against tilting. A threaded boss extends up from the platform and has a threaded internal bore extending vertically, to receive a threaded stud. The threaded boss comprises a relatively light plastic cylinder and has regularly extending buttresses stabilizing it on the platform. The special link is integrally formed by injection molding of a suitable material such as acetal, and is light in weight and profile.

Abstract: A surgical clip applier for use in closing wounds under the microscope in small blood vessels modifies a well-known clip applier system to make more steady and reliable the application of very small clips during surgery on a scale of vessel size of 2 mm in external diameter and smaller. The known device is modified internally so as to be capable of receiving a flexible remote actuation device which can be a cable release such as used for a camera shutter, or which can be a flexible hydraulic or pneumatic line as a force-transmitting device. Thus, the surgeon can hold the clip applier very steadily at the site desired without contracting any intrinsic muscles while the cable release is depressed by another person, or with the surgeon's other hand, or with a foot pedal.

Abstract: A radio frequency ID tag, very small in size and with an onboard antenna, is manufactured, tested and applied cost-efficiently. The transmit frequency for the tag is set during manufacture approximately, within a selected range, in a gross tuning step. A second tuning step fine tunes each tag by RF communication to set values of capacitance, resistance, etc., and this can be at the point of application of the tags. Other aspects include burning a randomly-selected value in the RF ID chip during manufacture to impose a random time delay for tag response (rather than having a random generator on the chip itself); structural testing of a large number of tags on a wafer using on-wafer interconnects and a special onboard sequencer test die; and production of the tag so as to be tunable to different frequency ranges.

Abstract: A medical pill intended for human or animal consumption includes an RF ID tag in or on the pill. The tag will respond to a nearby reader, the tag itself being without a battery or other constant power supply, capturing power from the reader's transmitted signal and storing a portion of that power in a power supply. An antenna for the RF ID tag may be integral with the tag or it may be transferred to the pill using conductive materials in the pill's coating, filler or binding agents, embedded within the pill, or printed onto the pill. If separate from the tag the antenna is electromagnetically coupled to the tag which has a small onboard antenna. The RF ID tag of each pill has data that are transmitted when the tag is interrogated by a signal from a reader. Incorporation of an ingestable ID tag is possible because of the tag's very small size compatible with ingestion and because the tag can contain an antenna within the pill that allows the tag to be read at a substantial distance.

Abstract: A modular plastic conveyor belt achieves a very tight turning radius. The belt is configured to permit the belt module rows to collapse using an over/under slotted module geometry, allowing for modules of one row to slip over/under modules of an adjacent row at the inside of a curve. This allows greater collapse and thus much tighter turning radii. A belt of two inch pitch can achieve an approximately 0.33 turning ratio, the ratio between turn center distance and width of belt.

Abstract: A wearable device for transmitting the resonant frequency of a solution to a biological system with the purpose of having a positive health influence on the biological system. Electrodes capable of conducting a small electrical current are placed in contact with the skin of an animal or human. These electrodes are connected to wires with an inline diode. A current results from the difference in electric potential of the two distal points on the skin, rectified into DC by the diode. Each wire is connected to one of two conducting leads. The leads are separated and submerged in a solution which has conducting properties. The current is modulated by the substance in solution and transmits this modulated current to the electrodes where the electromagnetic signature is transferred to the body. Thus by changing the substance in the solution the energy sensed by the body will differ. Careful and correct choice of the substance in solution will have positive influence on the health of the biological system.

Abstract: A modular plastic conveyor belt of the type made up of a multiplicity of module rows connected by interdigited link ends secured by pins has camming members at selected locations on the bottom surface of the belt to provide a flight dynamically. The camming members preferably are connected to two successive connecting pivot pins and hang down below the belt at an oblique angle during regular belt travel, sliding through grooves formed in the supporting track. At locations where a raised flight is desired to move products along with the belt, the camming member engages track structure so as to raise two module rows into an upwardly pitched roof-like configuration to form a flight. Hold-downs preferably are included before and after the location of the two involved module rows, to hold the belt flat to the support track or platform except at the flight itself.

Abstract: A bicycle is fitted with rear panniers that provide electric motor assist and a power supply for the bicycle when desired. In a preferred embodiment the bicycle has a power coupling permanently attached at the rear wheel, for receiving an output drive shaft or power coupling from the motor pannier when that pannier is installed. The drive coupling may have gear reduction. To accommodate relative up and down motion between the pannier-supporting rack and the rear tire in a rear suspension bicycle, the motor drive unit in the motor pannier articulates, or the final drive unit on the bicycle can articulate, but this is more difficult because the rear suspension motion can be complex. Both panniers are secured by a quick connect device, for both mechanical attachment and electrical connection. The bicycle functions as a normal unpowered bike when the panniers are removed.

Abstract: Maternity wear of the invention accommodates the changing shape of a woman's body during pregnancy, minimizing the need for maternity clothes. In one aspect of the invention, pants or a skirt are worn with the upper end unfastened so as to conform to the shape of the swelling torso in pregnancy, and an elastic band shaped similarly to a tube top is worn generally around the waist, so as to overlap the top of the unfastened pants or skirt and retain them on the body. A top, such as a blouse or shirt, can be worn with its tail end extending over the band. In another aspect of the invention, too-large maternity clothing is worn with the band garment engaged over the upper end. If desired the band garment can be folded over on itself, thus doubling its thickness.

Abstract: A hoist provides high mechanical advantage and accurate positioning, driven by hand or with a powered rotary implement such as a drill. The hoist includes flexible tension members, such as chains, cables or straps, for applying force and tension to a load. A load nut is connected to the tension members for high mechanical advantage from rotational drive input to a load screw threadedly connected to the load nut. Alongside the tension members are guides forming channel-like spaces within which the flexible tension members travel. The guides, or portions of the guides, pass through the load nut in most forms of the invention.

Abstract: In a wastewater treatment plant, the liquid side of the plant has preferably four stages for nitrification and/or denitrification, prior to further treatment such as a clarifier. Energy requirements are reduced by reducing aeration requirements. Four or more tanks/zones comprise serial anoxic and aerobic stages, but in the anoxic stages simultaneous nitrification/denitrification takes place in accordance with the known process of U.S. Pat. No. 5,906,746. By this arrangement the system can achieve a volume ratio of about 20% aerobic tankage to the total tankage volume, as compared to a much higher ratio in a typical prior art system of serial aerobic/anoxic stages, and greatly reducing aeration requirements.

Abstract: An aerobic digester system in a wastewater treatment plant is made more versatile for different conditions by addition of an equalizer basin or in some embodiments, a bypass pipe. If infeed is received from a sequential batch reactor or from a concentrated septage, for example, the equalizer basin can contain one batch, and then deliver the batch out incrementally to a gravity thickener basin. The equalizer basin also enables the gravity thickener of the system to be removed from service when needed, providing increased flexibility for the system. Importantly, the equalizer or bypass enables versatile modes of operation so that a plant designed for a larger, later flow can operate at an initially low flow or at several levels of flow before reaching the largest design flow. This applies to other conditions of variable flow as well such as seasonal.
