  • Publication number: 20190274537
    Abstract: Methods and systems for determining a physiological parameter of a subject through interrogation of an eye of the subject with an optical signal are described. Interrogation is performed unobtrusively. The physiological parameter is determined from a signal sensed from the eye of a subject according to a schedule, under the control of a scheduling controller.

  • Patent number: 9302729
    Abstract: A fork tube extension for motorcycles includes a cylindrical body having a reduced outer diameter at a first end forming a shoulder. A pair of the extensions is fitted between upper triple tree and lower triple tree portions of the motorcycle fork assembly. The fork tubes are fit up into the tube extensions in bored center cavities. Set screws provided in the cylindrical body are used to removably affix the fork tubes within the extensions. The depth of the center cavities determines the length of extension added to the fork tubes.

  • Publication number: 20110077568
    Abstract: A flexible, low profile hand splint includes a section of a hollow sphere or ball that comfortably puts the hand in an at rest natural position, while immobilizing one or more anatomical hand parts with extended spherical sections thereby immobilizing fingers, knuckles and tendons. Straps hold the splint onto the palm and immobilize one or more of the fingers. An inverse version of the splint provides protection to the injured soft tissue of a palm.

  • Patent number: 6662044
    Abstract: Patch-based devices for enhancing the local delivery of drugs, pharmaceuticals, plasmids, genes and other agents into the tissues of the living body. The patch devices provide an electrical driving force that can increase the rate of migration of drugs and other therapeutic agents out of a polymer matrix into body tissues and cells using iontophoresis only, electroporation only, or combined inontophoresis and electroporation. The two procedures may be applied sequentially in any order without removing or repositioning the patch.

  • Patent number: 6409651
    Abstract: The present invention provides a device (10), and methods of use thereof, for the targeted delivery of radiation, in vivo. The therapeutic radiation delivered by the device (10) of the present invention can be used, for example, to prevent restenosis after angioplasty. The catheter device (10) of the present invention is especially suited for such treatment because it substantially aids in the delivery of radiation to an intravascular treatment site. In addition, to delivering radiation emitting materials to an intravascular site, the present invention can also incorporate radiation shielding to increase the safety and accuracy of the delivery of the radiation emitting materials.

  • Patent number: 6168616
    Abstract: A stent delivery system having a stent the girth of which expands upon longitudinal compression, a pair of telescoping tubes where the inner tube has a greater length than the outer tube, and the stent surrounds the inner tube, a distal deployment strut fixedly connected at one end to the inner tube, and at the other end non-fixedly connected to the stent, a proximal deployment strut fixedly connected at one end to the outer tube, and at the other end non-fixedly connected to the stent, and an anchoring barb at the distal end of the stent.

  • Patent number: 6123681
    Abstract: An anti-embolism stocking used to inhibit the development of thrombophlebitis. The present invention is directed to a system and method for applying compressive forces to parts of the body to stimulate fluid flow through the parts of the body. In particular the present invention relates to a stocking that is capable of being placed on a portion of the body and then having a stimulus applied thereto to stimulate blood flow within the region of the body upon which the stocking is placed. The stocking includes polymer materials which, when a selected stimulus is applied thereto, causes constriction of the polymer, thereby causing the compressive forces. The stocking may be designed such that the compressive forces may be generated sequentially along the length of the stocking to gradually stimulate fluid flow, such as blood, to and from the preselected body portion.

  • Patent number: 5896556
    Abstract: An apparatus of the present invention is adapted to provide a telephone line connection over a coax cable distribution system. In a home having a plurality of set-top television boxes which each require a connection to a telephone line, the present invention allows a single telephone line connection to be provided to the plurality of set-top boxes via the coax cable distribution system. The invention uses a first interface device connected to a telephone line to modulate telephone signals and transmit them over the coax cable distribution system. The device also includes a demodulator to demodulate signals received over the coax cable distribution system to be sent over the telephone line. The invention includes a second interface device at each set-top box which also includes a modulator and demodulator to transmit and receive telephone signals over the coax cable distribution system.

  • Patent number: 5437052
    Abstract: An integrated bi-directional MMDS/MDS converter connected to an antenna for receiving MMDS programming for receiving information/data signals from a set top for retransmission of these signals back to central location. The integrated bi-directional converter has a down converter connected to the diplexer for down converting conventional programming signals into a group of converted programming signals in the 222 to 408 MHz range, an up converter for up converting data/information signals in the 116 to 128 MHz range from the communication line into MDS signals and delivers it into the diplexer. The diplexer applies the outgoing MDS data signals to the feed of the antenna for transmission. The integrated bi-directional MMDS/MDS converter of the present invention uses a common local oscillator for driving both the down converter and the up converter.

  • Patent number: 5246000
    Abstract: A phantom test cell and method for testing the response of a cardiac pacemaker to electromagnetic fields. The phantom comprises a substantially rigid shell which has a torso-like section and two leg-like appendages. The entire shell is filled with a tissue-equivalent material, which in one embodiment represents an upper bound approximation of human whole body averages. The phantom's torso is equipped with a plurality of access ports to which a current probe containment vessel may attach when immersed in the tissue-equivalent material. The containment vessel houses a current probe and flooded tube through which an implanted pacemaker's leads may pass, allowing induced currents to be monitored. In operation, lead current measurements are taken within the phantom and are normalized using measurements taken without the presence of a phantom. A transfer function is computed by taking the ratio of the induced current measured and a reference E-field and/or H-field measurement.

  • Patent number: 5119268
    Abstract: An electric power distribution device for insulated conductors has a substantially rigid base, a housing, and at least one series of spaced apart support blocks for supporting such conductors at intermittent positions along their length. The support blocks are substantially enclosed within the combination of the housing and the base, extending substantially from the base to a position in close proximity to the housing top. The support blocks are formed of a substantially inflexible material.

  • Patent number: 4397268
    Abstract: The present moisturizer for air going into a combustion process has a venturi passageway through a liquid permeable, porous, open-ended, annular body surrounded by liquid such as water and a valve in the venturi passageway. The valve is spring-biased toward the air inlet end of the venturi passageway to provide a maximum flow restriction at low volume demand. The valve deflects air outward against the inside wall of the porous body which defines the venturi passageway for the purpose of enhancing the withdrawal of moisture from the porous body, particularly at low volume demands. At progressively higher volume demands, the valve is displaced by the air toward the air outlet end of the venturi passageway to enlarge the effective open area of the passageway around the valve. Preferably, the valve operates to keep the air velocity through the venturi passageway substantially constant at different air flow demands.
