Abstract: The  lumber transfer system is  for transferring parallel lumbers from a feeding conveyor to an outfeed conveyor and regularly spacing the lumbers thereon. The lumber transfer system comprises a loader comprising a plurality of carrying disks provided with a plurality of grasping means. Each grasping means comprises a tooth provided on an outer edge of the disk, a lumber grasping arm and a rotary actuator for rotatably mounting one end of the arm aside and parallel to the disk. The rotary actuator  is  rotating alternately the  arm towards  a closed position near the tooth and is acting as pliers therewith for grasping and holding a lumber lying at a delivering end of the feeding conveyor and towards an open position so that the lumber is not held by it. The operations of the rotary actuators are synchronized in function of the rotation speed of the disk so that each lumber arriving at the delivering end of the feeding conveyor is stopped, released to be transferred by one tooth provided on each disk and then grasped by the corresponding arms as they are rotated towards their closed position. The lumber is then transferred to the outfeed conveyor and laid on a loading end thereof as the arms are rotated towards their open position. The lumbers transferred  on  the  outfeed  conveyor  are regularly  spaced  apart.  Advantageously,  the  lumber transfer  system  according  to  the  present  invention allows the handling and transfer of different sizes and shapes  of  lumbers.  It also  allows  to  increase  the feeding speed rate.

Granted: 2005-07-05
Abstract: A mask and harness system for use in providing breathing oxygen and protection from pollutants for the eyes and respiratory system as might be encountered in high altitude aviation environments. In one preferred embodiment, the mask system has a face seal, a soft flexible lens, a pneumatically-actuated harness, and a regulator with microphone to control the f low of oxygen and to facilitate communications in aircraft flight decks and other aircraft compartments. The system is designed for required five-second donning with one hand and because of the flexible lens, is capable of storage in the relatively preferred on crowded flight decks. It is connected to an oxygen source and, optionally, with aircraft communications. The regulator controls the flow rate of oxygen to the wearer based on altitude and physiological requirements. The regulator includes a valve for purging the condensation-prone moist gases from the lens area and provides positive pressure in the mask.      A second preferred embodiment molds the lens and mask seal of a single material having sufficient optical quality and flexibility to accomplish both purposes.

Title: Self-verifying identification card
Inventor: KRISTOL DAVID MORRIS
IPC: G06K17/00
Filed: 1996-02-27
Granted: 2000-03-07
Abstract: A self-verifying identification card having an image area which may contain a portrait, a finger print, a retinal image, or all of these together with an image signature which is derived from scanned intensity measurements taken from the image area.  In the verification process, the image is scanned and aligned with respect to reference points corresponding to the original printing process which created the card, and intensity values, their averages, or any other function are compared to information provided by the image signature.  Mathematical transformations, such as a one-way hash, an encryption, a compression algorithm, or a truth table may be used to encode the image signature. Alignment markers aid in scanning the image and the image signature.  The use of average values aids in reducing noise and the use of comparison functions makes the process less sensitive to variations among scanners.  The verification may be done at the point of a transaction, for a standalone system, or may be referred to a centralized data base in a networked system for further inquiry.  In a networked system the image signature may be stored in the database.

Filed: 1996-05-16
Granted: 1999-07-27
Abstract: An apparatus (20) for controlling movement of a vehicle power window (22) between a fully open position and a fully closed position.  The apparatus (20) comprises an energizable electric motor (66) for, when energized, moving the window (22).  A switch assembly (62) for energizing the electric motor (66) to move the vehicle window (22) to one of the positions.  The switch assembly (62) includes a first electrical contact (282) and a second electrical contact (284) electrically insulated from the first electrical contact.  An electrically conductive disk (286) has a periphery (288) domed portion (290) and is in electrical communication with one of the first and second electrical contacts (282, 284) at a portion of a periphery of the disk.  The other of the first and second electrical contacts (282, 284) is located adjacent the disk (286) and initially spaced from the disk.  The disk (286) is resiliently deflectable into engagement with the other of the first and second electrical contacts (282, 284) to provide electrical communication between the first and second electrical contacts.  A member (104) is supported for movement and is movable in response to manual force applied thereto.  Movement of the member (104) effects deflection of the domed portion (290) of the disk (286) into engagement with the other of the first and second electrical contacts (282, 284) to energize the electric motor (66) to move the window (22) in a direction towards one of the positions.

Title: Fetal electrode product with easy-to-handle connector
Inventor: URION KENARD E
IPC: A61B5/288
Filed: 1996-06-13
Granted: 2007-09-04
Abstract: A fetal electrode product for transmitting signals indicative of fetal heart rate from a fetus to a monitor. The product includes a slotted introducer which can be comfortably inserted through the cervix of the mother. A drive mechanism slides and rotates a holder --to which are attached, at opposite ends, a fetal spiral electrode (FSE) and a reference electrode--within the introducer to secure the FSE to the fetus. The solid drive mechanism has a drive rod, a handle on one end of the drive rod imparting translation and rotation to the drive rod, and a clutch on the opposite end of the drive rod imparting translation and rotation to the holder. The drive rod, handle, and clutch each have a channel transporting a twisted wire strand from the electrodes to a connector. The connector has an outside dimension greater than the inner diameter of the introducer to facilitate manipulation. The introducer cannot be pulled over the connector after the FSE is attached to the fetus; the wire strand exits the drive mechanism via its channel and the introducer through its longitudinal slot. A locking slit in the handle securely wedges the twisted wire strand in a fixed position before application of the FSE. A chamfer located at the intersection of the slot with the rearward end of the introducer also positions and helps wedge the twisted wire strand in a fixed position.

IPC: H04B10/071
Filed: 1996-10-04
Granted: 2005-06-21
Abstract: An optical time domain reflectometer suitable for determining its front panel insertion loss comprises a four-port coupler having first and second ports connected to a light source and an optical detector, respectively, and third and fourth ports connected to a front panel output connector and a reference reflector, respectively. In use, a fiber-under-test is connected to the front panel output connector. The coupler splits light from the light source between the front panel output connector and the reference reflector and couples light returning from the front panel output connector and roflector to the detector. The optical path between the front panel output connector and the coupler is longer than the optical path between the reference reflector and the coupler by such a distance that a Fresnel reflection pulse from the reference reflector, produced by a pulse emitted by the light source, will be received by the detector before a corresponding reflection pulse returned from the front panel output connector. In order to ensure that the two reflection pulses can be distinguished from each other, the difference between the two optical paths is greater than a distance equal to an event dead zone for the particular width of pulse supplied by said light source. The reference reflector comprises an end portion of a length of optical fiber, preferably encapsulated with a material having a refractive index different from that of the length of optical fiber. The OTDR facilitates miniaturization because it avoids the use of an internal length of reference fiber,
