Title: Resynchronization of encryption systems upon handoff
Inventor: DENT PAUL WILKINSON
IPC: H04L9/00
Filed: 1991-07-18
Abstract: A system for the synchronization of encryption and decryption in a duplex cellular radio system in which an encrypted call may be switched from one cell to another.  At the instant of handoff, a rapid first resynchronization means temporarily seizes the voice channel in one direction only and transmits synchronization information in such one direction.  The first resynchronization means ceases to transmit the synchronization information and releases such one direction of the voice channel as soon as an indicator of successful synchronization is detected in the other direction.  Transmission of speech traffic in such one direction is then resumed after such detection of successful resynchronization. To avoid occupying such one direction with continuous transmission of the synchronization information in the event successful resynchronization has occurred but has not been detected due to faulty transmission in the other direction, an upper limit is set on the length of time which the first rapid synchronization means may cease such one direction.  After such timeout, resynchronization information may be provided by a second resynchronization means at a slower rate through a slow rate control channel bit stream which is multiplexed with the traffic data.

Patent CA-2091332-A1 (CA)
Title: Semiconductor non-volatile memory with tunnel oxide
Inventor: WALKER ANDREW JAN
IPC: H01L29/51
Filed: 1993-03-09
Abstract: Very thin tunnel oxides are used in conventional non-volatile memories to obtain a sufficiently strong tunnelling current to or from the floating gate.  Usual thicknesses of the tunnel oxide lie in the 8-10 nm range. The invention renders it possible to use tunnel oxides of a much greater thickness, for example of the order of 20 nm, for comparable tunnelling current values.  According to the invention, the tunnelling effect is enhanced by implantation of a heavy, high-energy ion, for example As, into a comparatively thin poly layer of the oxide. During this, Si atoms are propelled from the polylayer into the oxide, so that the oxide is enriched with Si, which causes a major change in the tunnelling characteristics. The same oxide which functions as a gate oxide elsewhere may be used for the tunnel oxide. An important advantage of the invention is that direct contact between the tunnel oxide and photoresist layers necessary during the process is avoided, so that the properties of the tunnel oxide are not or at least substantially not impaired by the photoresist.

Title: Non-visual labyrinth puzzle "hidden crazy maze"
Inventor: CARAMANOFF GEORGE C
IPC: A63F7/04
Filed: 1993-04-13
Abstract: ABSTRACT       A puzzle consisting of a ball bearing enclosed in a labyrinthian passageway, section of the passageway being unobscured from view by an opaque screen.  A closed loop may be traced through the passageway, a section of the closed loop being obscured by the opaque screen.  The object of the puzzle is to maneuver the ball bearing through the visually obscured region of the labyrinth from one end of the unobscured region of the closed loop to the other end.  Solution of the puzzle requires the utilization of auditory and tactile information as the ball bearing rolls through the labyrinth and strikes the walls of the passageway.  Because visual information is suppressed, negotiation of the labyrinth requires considerable visualization ability and mental dexterity, and allows for the design of challenging labyrinth puzzles with a minimum of bulk.

Title: Crane having turntable lock, swing-away hoist mount, and boom rest
Inventor: GROVE JOHN L
IPC: B66C23/62
Filed: 1993-07-19
Abstract: Abstract of said Disclosure A truck mounted crane assembly includes a turntable lock, a boom rest which interacts with the piston and cylinder device,  and a swing away hoist mount.   The turntable  lock  includes  a  pin  which  is  manually retractable upon rotation of a handle from a position preventing relative rotation between a turntable and a pedestal to a position allowing such relative rotation and which  can  be  secured  in  the  first  and  second positions.   The boom rest is mounted on the boom and rests on the cylinder of the piston and cylinder device when the boom is lowered to a predetermined position, thus taking much of the pressure off the piston.  The boom rest is movable from a position in which it is capable of supporting the boom to a position in which it is incapable of supporting the boom and in which the boom is thus lowerable below the predetermined position.  The provision of the turntable lock and boom rest obviates the need for a cradle rest for the boom.  Finally, the hoist mount receives the hoist, is connected to the boom, and  is  movable  under  actuation  of  the  hoist  or telescoping of the end of the boom from a first, working position to a second position allowing access to the interior of the front end of the boom.

Filed: 1993-11-10
Abstract: A surface of a ceramic article, such as a glazed surface on a whiteware article, is treated with radiant energy such as infrared light from a laser to provide a localized remelting of the material at the surface in a fusing step. After the fusing step, the surface is treated with further radiant energy, desirably over a larger surface encompassing the fused zone and also desirably at a lower power density so as to limit the rate of cooling of the fusion zone and the immediately surrounding regions, thereby preventing thermal stress cracking. The fusion zone and surrounding regions desirably are preheated by additional radiant energy immediately prior to the fusing step so as to further limit thermal stresses during the fusing step. The process can be employed, among many other uses, for repair of glaze defects and for decoration. <IMAGE>
