Granted: 1994-03-08
Abstract: N-CHANNEL CLAMP FOR ESD PROTECTION           IN SELF-ALIGNED SILICIDED CMOS PROCESS            ABSTRACT OF THE DISCLOSURE      An electrostatic discharge  (ESD) protection device is formed in an integrated circuit by an N-channel grounded-gate transistor.  This protection device has a polysilicon gate, just as other P- and N-channel transistors in the integrated circuit device, but the siliciding of the protection device is controlled  so  that  adverse  effects  of  ESD  events  are minimized.  The siliciding of the protection transistor near the gate is prevented by using a deposited oxide layer as a mask, and this oxide layer is also used to create sidewall spacers for the transistor gates.  The sidewall spacers are used  in  creating  self-aligned  silicided  areas over  the source/drain regions, self-aligned with the gates, for all P-and N-channel transistors except the protection transistors.

Title: Apparatus for gravel packing a well
Inventor: JONES LLOYD GARNER
IPC: E21B43/04
Filed: 1992-01-28
Granted: 2000-01-18
Abstract: A sand screen is positioned in a well adjacent an oil or gas reservoir to be produced. At least one conduit is in juxtaposition with the sand screen and has passageways at selected intervals to establish fluid communications between the conduit and the annulus of the well surrounding the sand screen. A gravel packing slurry is injected down the well to form a gravel pack in the annulus. Actuatable devices associated with the conduit passageways control fluid flow between the conduit and annulus so that if the gravel portion of the slurry forms a bridge in the annulus, thereby blocking slurry flow throb the annulus, the slurry will be diverted from the annulus into the conduit through one or more of the passageways in the conduit above the bridge, downward through the conduit and out through one or more passageways in the conduit into the annulus below the bridge to continue the forming of the gravel pack in the annulus.

Patent CA-2079827-C (CA)
Inventor: WANG THERESA CHEN YEN
IPC: H04B7/185
Filed: 1992-10-05
Granted: 2003-08-19
Abstract: A communication network keeps track of the locations of mobile units which utilize the network.      On powering up, the mobile units determine their current locations using signals broadcast, for example, by overhead satellites. They then send data communication messages to the network describing their locations. The network saves the locations and returns data messages that describe borders which surround the mobile units' locations. The mobile units repetitively determine their current locations on a regular schedule. When their current locations are outside of their prescribed borders, they send other location data messages to the network to update the location data being maintained by the network and to receive a definition of a new border.
Patent CA-2088725-C (CA)
Inventor: HULLAND BURTON L
IPC: G01S13/933
Filed: 1993-02-03
Granted: 1997-12-16
Abstract: The range from which a collision avoidance system at an Own station can receive  secondary surveillance radars (SSR) interrogations and reply messages from Other stations, is extended by utilizing P2 pulses for timing time of arrival (TOA) measurement in the event P1-P3 pulse pairs are unavailable from the scanning main beam or its side lobes.          The amplitude of the P2 pulses in the SLS radiation pattern being greater than the P1-P3 side lobes of the main beam over an angular sector of about 60° centered on the main beam can insure reception of P2 pulses at much greater ranges than P3 pulses contained in the main beam side lobes can be reliably received.  Using P2 timing, interlaced Mode A and Mode C reply messages contained in a main beam burst reply sequence are separated into two "families" of TOAs, the Mode C (altitude) TOAS always being longer than the Mode A TOAs by 13 µsec. A " true" TOA is obtained by subtracting an appropriate time period from the TOA of each family, from which identity, altitude and range information is readily derived.  The system continuously adapts to the best instantaneously available timing pulses, alternating between P3 timing and P2 timing throughout the time it takes for a main beam rotation of the received SSRs, thereby extending the operation area of multiple TOA measurements from multiple SSRs which, in turn, provides added safety and reduced false alarms compared to prior passive collision avoidance systems.
