Patent CA-2191332-C (CA)
Inventor: COLLINS JOHN S
IPC: G06F40/14
Filed: 1995-05-24
Granted: 2000-10-17
Abstract: A computerized system receives characters (219), each having an associated font (217). For each character-font com bination received it accesses a pre-defined font description (in 122) of that combination's shape (453) and then generates a new font description (in 126) of that shape. Preferably when the characters have different fonts, the system automatically creates new font descriptions for all of them. Preferably the received characters are part of an input text (116), and the system produces an output text (104) which includes not only corresponding characters (219A), but also the new font descriptions necessary to define those character's shape. Preferably the output text can be transferred to other computers by recording media (130) or computer network (132). Preferably the new font descriptions are independent of the manner in which pre-defined font descriptions define character-font shapes. Preferably the system can render an image (in 110) of the output text, either on the computer which created it (102A, 102B), or on another computer (108A, 108B).

Title: Easy drive concrete fastener system
Inventor: DITKA MICHAEL P
IPC: F16B19/00
Filed: 1996-12-30
Granted: 1999-06-15
Abstract: A depth-insensitive concrete  fastener system is provided for securing roofing insulation materials to concrete roofing  or  decking.    The  concrete  roofing  or  decking substructure is provided with a pre-drilled hole or bore having a predetermined diametrical extent.   An anchor bolt fastener comprises a head portion, a pointed tip portion and a shank portion interconnecting the head and tip portions. The shank portion has a first relatively smooth shank portion disposed adjacent to the head portion and extending toward the tip portion and a second ribbed portion disposed adjacent to the tip portion and having an axial extent which is only a fractional portion of the entire axial extent of the fastener. The diametrical extent of the first smooth shank portion is less than that of the pre-drilled hole or bore defined within the concrete substructure, whereas the diametrical extent of the  second  ribbed  shank  portion  is  greater  than  the diametrical extent of the pre-drilled hole or bore defined within the concrete substructure.  Therefore, when the anchor bolt fastener is impactly driven into the pre-drilled hole or bore of the concrete substructure, an interference or friction fit is defined between the anchor bolt fastener and interior sidewalls of the concrete substructure defining the pre-drilled hole or bore only along the axial extent of the second ribbed shank portion of the bolt fastener.  Consequently, the fastener  system  is  rendered  depth-insensitive  in that regardless of the depth to which the anchor bolt fastener is driven into the concrete substructure, the installation force does not increase beyond a predetermined limit.  A roofing washer element may be pre-assembled upon the anchor bolt fastener as a result of being captured between the head and second ribbed shank portions of the bolt fastener.

Abstract: A method and system for preserving state in computers communicating over networks, such as the World Wide Web (WWW) using stateless protocols, e.g., HTTP. State is preserved in a conversation between a client requesting services from a served by performing the service and identifying all continuations (hyperlinks) in an output from the service; recursively embedding the state information in all identified continuations in the output sent to the client. The state information may be embedded and communicated by the server to the client. Alternatively, dynamically downloadable program code may be used to embed the the state information at the client. Additional features enable the filtering and/or addition of hyperlinks and data output from the services according to predetermined criteria. State information may be embedded by modifying an identified continuation which is a request for an HTML file, to invoke a CGI converter program with the identified continuation and the state information passed as arguments. State information may also be embedded by modifying an identified continuation which is an invocation to a CGI program with the identified continuation and the state information passed as arguments, and the embedding step is performed by the CGI program. Alternatively, an identified continuation which is an invocation of a CGI program may be modified to invoke a CGI converter program with the identified continuation, an argument counter which indicates a number of arguments associated with the CGI program, and the state information passed as arguments. Here, the embedding is performed by the converter program.

Title: Wellbore profiling system
Inventor: ADAMS JOHN R
IPC: E21B47/022
Filed: 1997-09-17
Granted: 2001-08-07
Abstract: A method is presented for accurately surveying and determining the profile of the path of a subterranean wellbore containing a constant density fluid extending contiguously throughout. A first pressure sensor, associated with a downhole tool, is traversed station-by-station along the wellbore for measuring the pressure of the fluid within the wellbore at each station. A second pressure sensor is located within the wellbore fluid at a known elevation. The elevation of the first pressure sensor, at a station, is determined by adding the calculated differential height to the known absolute elevation of the second sensor. As each elevation is referenced to the second sensor, no cumulative errors are incurred. If the density of the fluid is unknown, a third pressure sensor within the wellbore fluid can be provided at a known elevation different from that of the second sensor. The areal position of each station is determined by conventional means associated with the downhole tool. The elevation for each of a plurality of stations is combined with the areal position determined at each station to determine the path of the wellbore.

Title: Exit spark control for an electrosurgical generator
Inventor: BEK ROBIN B
IPC: A61B18/12
Filed: 1996-06-03
Granted: 2001-08-14
Abstract: An electrosurgical generator (10) is disclosed that includes an exit spark control system. Exit sparking occurs when energy arcs to the patient (13) as the active electrode (12) is withdrawn from the patient (13). A basis for controlling the exit spark is to automatically change the frequency at which the final amplifier is driven whenever the conditions for an exit spark are detected. The change in frequency acts to lower the gain and efficiency in the final amplifier and dissipate energy as heat. The exit spark control system includes a frequency adjustable waveform generator (14) and a logic capability for determining the conditions when exit sparking is likely to occur. Sensors and an algorithm in a microcontroller (16) are preferably required to detect the conditions preceding exit sparking occurrence. It is further preferred that, the algorithm also controls the sequencing of events: first stopping the electrosurgical output to prevent an arc from initiating and then changing the driving frequency appropriately to dissipate excess stored energy. The output waveform may be stopped for only a short time or the surgeon will detect drag while cutting through tissue.
