Abstract: A method and apparatus of obtaining and reconstructing an image of a portion of a body, administered by a radiopharmaceutical substance, by using Single-photon emission computerized tomography (SPECT) for determination of functional information thereon.

Abstract: An electronic article surveillance system is disclosed. The system utilizes interaction between magnetic fields generated by a plurality of antennae elements to generate magnetic field in different orientations within an interrogation zone. The antenna elements are fed in different phases in accordance to phase patterns to generate the different orientations. A novel receiving antenna construction for receiving the perturbations caused by re-magnetization of a marker within the interrogation zone is also disclosed. The antenna construction comprises a receiving coil at a certain distance from the transmitting coil, and a compensating coil closer to a transmitting coil. A method for utilizing the system is also presented.

Abstract: A diode detector comprising a detector network adapted to detect and multiply the detected voltage coupled to a divider network that comprise diodes in equal number to the number of diodes in the detector network, provides a passive detector applicable to any application requiring a small, efficient, high output, inexpensive temperature compensated detector for use as demodulator or as power to voltage converter.

Abstract: A drill head capable of attachment to a drilling machine for insertion of rock bolts into rock strata. The drill head comprising: a base block adapted to facilitate attachment to the drilling machine; driving spindle mechanism having a member at one end which receives a proximal end of a rock bolt including an internal cavity; an injection assembly including at least one internal passage for retaining a grouting compound. When the rock bolt is inserted in the member and when the injection assembly engages the member, the passage is in communication with the internal cavity in the rock bolt; whereupon the injection assembly operates to inject a predetermined quantity of the grouting compound into a bolt hole in the rock strata via the internal cavity of the bolt.

Abstract: When a pipeline is used as a medium for data transmission using a VLP or ELF Electro-magnetic signal the presence of corrosion effects on the pipeline lead to noise signals appearing in the received data signal. The present invention relates to a method of separating out this noise signal and analyzing it to determine the corrosion status of the pipeline. Both the type and location of the corrosion effect can be determined in this way.

Abstract: A mouthpiece for a hydration system designed for drinking liquids from that system. The mouthpiece comprises a body having an internal conduit passing through it, the internal conduit having a broad portion provided with a broad opening and a narrow portion provided with a narrow opening, a piston member having a distal portion and a proximal portion, the piston member provided with a passageway passing through it, the passageway having a first opening at the proximal portion and a second opening between the proximal portion and the distal portion. At least a portion of the piston member is inserted in the conduit fitting inside the broad portion while the distal portion of the piston member is adapted to fit inside the narrow portion. The piston member is adapted to coaxially move within the body. The mouthpiece further provided with an O-ring closely encircling the distal portion of the piston member.

Abstract: A method and apparatus for generating colored images of at least one color within a light-sensitive glass sample. The glass sample contains light-sensitive chemical components that acquire at least one of a multiplicity of colors in response to actinic radiation and subsequent heating to a temperature that causes color to appear. The method comprises focusing a pulsed laser beam to a target location within the glass, irradiating a plurality of pulses focused in the target location within the glass sample, thus generating a zone of increased opacity to the visible light at the target location and a resultant localized actinic radiation at that zone, displacing the focus point of the laser beam and the glass sample relative to each other by the displacing device in a predetermined manner so as to produce a plurality of zones of increased opacity that form an image, and heating of the sample to a temperature that causes color to appear at the zones of increased opacity.

Abstract: A dispenser for dispensing metered amount of liquid into a toilet cistern, comprising a basin adapted to receive a metered amount of dispensable liquid received from a container via a discharge spout. An airlock prevents further discharge of liquid above a predetermined amount in the basin when the discharge spout is covered by the dispensable liquid. A siphon inlet is in liquid communication with the metered amount in the basin, and the siphon outlet is in liquid communications with the cistern water at quiescent times. Upon flush, the siphon siphons out the dispensable liquid in the basin, breaking the airlock, and allowing a new metered amount of dispensable liquid to flow to the basin, ready for next flush.

Abstract: An orthopedic guide to aid in donning an ankle foot orthosis (AFO) is disclosed comprising an L-shaped channel and a rocker to allow the L-shaped channel to smoothly rotate generally about the L-shape joint when tilted. The horizontal portion of the L is weighted to urge the device to an upright position when at rest. A shoe and an AFO are placed in the L-shaped channel and a patient foot uses the vertical portion of the L to guide the patient foot into the shoe. In use the device tilts to create a natural rotation movement for the foot insertion, and places the foot and guides it in a more comfortable tilted position. A shoe tongue retainer clip is also disclosed to allow further ease in donning the shoe and AFO by enlarging the shoe opening and keeping the tongue out of the way.

Abstract: A device for securing a nasal cannula to a patient's head is disclosed. The device utilizes a thin round elastic band placed behind the patient's head and is attached to the cannula gas supply tube by cord couplers. The cord couplers are slidably attached to the gas supply tubes to allow fast and easy adjustment to size. The device is light, comfortable, inexpensive and simple to use. It prevents painful hair entanglement and allows single handed deployment and adjustment of a nasal cannula, while affording secured placement of the cannula during patient movement or sleep. Additionally, a nosepiece having a downwardly oriented U shape or arcuate fold in its center portion is disclose to prevent the cannula nosepiece from exerting excessive pressure against the patient's septum. A method of use is also disclosed.

Abstract: An implement for picking up and removing pet excrement from a surface, comprising a string element, a disposable flexible sheet that my be coupled to the string element, so as to form an edge of the sheet led by the string element, the sheet being removable from the implement, and an isolation mechanism for isolating the pet excrement from the surface by way of sliding the sheet between the pet excrement and the surface while maintaining the string element in a tautly stretched configuration so long as the string element is in close contact with the surface, the isolation mechanism comprising a grip for gripping and moving the isolation mechanism by the hand of the user.

Abstract: An apparatus and method for preventing misdialing of a telephone number, especially fit for facsimile transmission is provided. The invention operates by dialing precompiled control keys added to the telephone number. The control keys are compared against computed control keys and transmission is allowed or denied according to the match between the dialed and computed control keys. The invention may be implemented in software embedded within the dialing device, in a telephone switch, telephony router, or by a special apparatus inserted anywhere in the transmission path.
