Abstract: A keyboard can be comprised of a plurality of alphabetic keys that are disposed in an evenly-spaced grid pattern with respect to one another. In any event, these keys have keycaps configured to comport with touch typing as with a keyboard having a plurality of alphabetic keys that are disposed in an offset pattern (such as the classic QWERTY offset-pattern typewriter-styled keyboard). By one approach, these keycaps can have keycaps having bilaterally-nonsymmetrical tactile features that at least substantially match standard touch-typing finger positions. By one approach these tactile features can comprise an indentation.  If desired, these keycaps can share a same form factor. In such a case, some of the keycaps for the alphabetic keys can be disposed on the keyboard at a 180 degree rotation as compared to others of the alphabetic character keycaps.

Patent CA-2754361-A1 (CA)
Inventor: BURKE EDWARD J
IPC: E05B35/00
Filed: 2010-01-28
Abstract: A locking system for securely closing the lid (22) on an enclosure, such as a grade level box, includes an L-bolt (52) connected to a spring-biased slide member (26) positioned on the underside of the lid (22). The L-bolt (52) rotates in a slotted housing that securely retains the L-bolt (52) under the lid. The slide member engages an abutment on the inside of the enclosure, when the lid (22) is forced down over an opening in the enclosure, e.g., by foot pressure. Downward force on the lid progressively causes the latch to retract against the spring-bias from contact with the abutment and then snaps the latch into a spring-biased locking position under the abutment. The L-bolt (52) is accessed from outside the lid (22), rotated by a proprietary socket wrench or similar tool, to retract the latch from its locking position sufficiently for removing the lid from the enclosure.

Title: System and method for performing optimized downhole stimulation operations
Inventor: COHEN CHARLES-EDOUARD
IPC: E21B43/00
Filed: 2013-01-30
Abstract: A method of performing a stimulation operation for an unconventional wellsite having natural fractures and hydraulic fractures. The method involves providing at least one treatment parameter with a corresponding objective function value and performing a fracture operation based on the treatment parameter. The fracture operation involves defining a treatment schedule, conducting a hydraulic fracture operation, and estimating production. The objective function value is based on an objective function. The method also involves modifying the treatment parameter and performing the fracture operation based on the modified treatment parameter. The modified treatment parameter has a corresponding modified objective function value based on the objective function. The method continues with optimizing the treatment operation by comparing the objective function value with the modified objective function value, and repeating the modifying and optimizing for new modified treatment parameters until convergence about a desired outcome whereby an optimized parameter is defined at convergence.
