Inventor: CHAN SHIU K
IPC: G11C7/22
Filed: 1991-06-07
Abstract: Speeds  up  computer  memory  system  operations  by providing a memory fetch cycle that is shorter than the memory store cycle.  To do this, the invention changes the timing of the recovery part of the fetch operation in the semiconductor memory chips of the memory.  Each chip has at least one dynamic random access memory array (DRAM) and a small high speed cache memory (SRAM) on the chip.  The system memory controller recognizes the fetch or store state  of  a  memory  request  in  generating  a  DRAM subrow-address timing signal  (RAS)  and a cache address timing  signal  (CAS)  for  enabling  the  accessing  and addressing of bits in the SRAM and the recovery in the DRAM.  The invention controls RAS to start DRAM recovery for a fetch cycle near the start of fetching of data from the SRAMs on the chips, but controls RAS to not start DRAM recovery for a store cycle until SRAM data storing is done.   The  clocks  on the  chips  contain circuits  that enable  fetching  of  data  from  the  SRAMs  during  DRAM recovery,  but that prevent DRAM recovery from starting until data storing in the SRAMs is complete.

Abstract: A two-loop strap restraint for law enforcement is lightweight, strong, inexpensive, disposable, and can be formed entirely of recyclable polymeric material, and is easy to apply and carry. This restraint has a pair of apertures in its central bridging portion for curling into a compact four-loop configuration for easily carrying several of them in an unobtrusive, concealed manner in a pocket. The restraint fits all size wrists, ankles for use in a wide variety of law enforcement situations. It has the general form of a single non-metal elongated strap of polymeric material having a pair of symmetrically positioned latching socket bosses of polymeric material located near the center of the strap with a resilient latching pawl formed of polymeric material positioned in each socket. A flexible ratchet portion of the restraint extends outwardly from each socket boss with a narrow tip pull extending outwardly from the ratchet portion to a rounded tip. In use, a tip pull is inserted through a socket opening. The resilient pawl allows the flexible ratchet portion to be drawn forwardly in an insertion direction through the socket for engaging snugly around a wrist, ankle or anchoring member, then the pawl prevents the inserted ratchet portion of the strap restraint from being moved backwardly from the socket in an extraction direction for securely holding a restrained limb (arm or leg). The socket bosses project solely toward the outside of the restraint for facilitating quickly, properly inserting tip pulls into socket mouths in the dark.

Title: Check valve for use with particle slurry
Inventor: BARREE ROBERT D
IPC: F16K17/04
Filed: 1991-06-28
Abstract: Abstract of the Disclosure A check valve especially suited for use with a sand slurry.  The check element comprises a frusto-conical surface which engages a sharp edged seat.  The surfaces forming the seat intersect at an acute angle, preferably in the range of 30° to 60°.   Contact between the sloped surface of the check element and the seat edge pushes sand particles aside and prevents them from interfering with the closing of the valve. A spring which urges the check element toward the seat is segregated from the slurry to prevent fouling of the spring.            RH

Title: Optical device designed for the introduction of a collimated image into an observer's visual field and enabling night vision
Inventor: MONNIER LAURENT
IPC: G02B27/00
Filed: 1991-07-24
Abstract: ABSTRACT OF THE DISCLOSURE    The disclosure relates to optical devices enabling daytime vision and night  vision of the external  scene with, in  both  cases, the  superimposed  introduction, into the observer's visual field, of an image given  by an image  generator.  The  image  given by  the  light intensifier of a night observation system is  processed in the  same way  as  the image  given  by  the  image generator, by  means  of an  auxiliary  image-combining optical system which mixes these two images before they reach the main  image-combining optical  system of  the device through  which, in  night vision,  the  observer directly  sees  the   external  scene.  The   auxiliary image-combining optical system is designed so that,  in night vision, at least the  greatest part of the  light coming  from  the  image  generator  reaches the  main image-combining  optical  system.   Depending  on   the embodiment, this  result  is  obtained  either  with  a retractable   semi-reflecting   mirror   or   with    a semi-reflecting surface selective in frequency.

Abstract: ABSTRACT OF THE DISCLOSURE     An instrument for and method of effectively treating the prostatic urethra so as to relieve the symptoms associated with an enlarged urethra is disclosed.  The tissue of at least selected portions of the prostate are compressed (preferably with a balloon inserted into the prostatic urethra so as to enhance hemostasis) and at least selected portions of the compressed tissue are directly irradiated (preferably with a laser beam transmitted from within the passageway in selected radial directions and moved along the prostatic urethra while exposing the tissue) so as to cause coagulation necrosis of selected portions of the compressed tissue so that as the tissue heals, the necrosed tissue slowly sloughs off during normal urination through the urinary tract so as to effectively remove the constricted portions of the prostatic urethra.  Ultrasonic transducers are used from within the prostatic urethra to image the tissue as it is irradiated so as to monitor the procedure to insure proper exposure to the laser beam.

Title: Traveler security and luggage control system
Inventor: BRAVMAN RICHARD
IPC: G07B15/00
Filed: 1991-11-19
Abstract: ABSTRACT   A bar code is used to identify a traveler's luggage, permitting the luggage to be tracked and, if desired, to be delivered to the traveler's ultimate destination (e.g., a hotel). If the traveler is traveling on an airline, a corresponding bar code is ap-plied to the traveler's boarding pass. A bar code reader is used to read the boar-ding-pass bar code of each emplaning passenger; comparison of these bar codes with luggage bar-code data permits an alarm to be raised if each item of checked luggage is not matched by an emplaned passenger. The boarding-pass bar code may take theform of an integrated passenger identification code for use by, e.g., rental car corn-panies, hotels, and the like.
