Patent CA-2140620-A1 (CA)
Title: Modeling with a reduced activity set
Inventor: THOMSON VINCENT
IPC: G06F9/00
Filed: 1994-12-20
Abstract: A method is provided for generating information on a computer system that relates to preforming a task or a work activity. A user is required to decompose the task or work activity into processes, subprocesses, that are further decomposed into steps and eventually micro-steps. As this decomposition occurs the system builds a network of interrelated processes, subprocesses, micro-steps and atomic level activities and stores information related to the ordering of the atomic level activities inaccordance with their relative positional relationship in the network. All process are eventually decomposed into one or more of three atomic level activities: a store/retrieve activity, a transform activity or a transport activity. A suitably programmed processor processes the data associated with each micro-step related to each ordered atomic level activity through an atomic level activity executor.

Title: Lock assembly actuatable by an electrical motor and/or a mechanical key
Inventor: AHARONI MORDECHAI
IPC: E05B47/00
Filed: 1995-03-07
Abstract: ABSTRACT OF THE INVENTION     A lock assembly which includes a key-driven shaft rotatable by a key and a lock drive shaft coupled to a locking bolt for driving the locking bolt to locking and unlocking positions. The assembly further includes an electrical motor having a motor transmission. Finally, the assembly includes a yieldable coupling which normally couples the motor transmission to the lock drive shaft in order to drive the locking bolt to locking or unlocking positions. The yieldable coupling is yieldable upon overload of the lock drive shaft to decouple the motor transmission therefrom. The key-driven shaft is axially displaceable to decouple it from the motor transmission, thereby enabling the key-driven shaft to drive the lock drive shaft and the locking bolt to locking or unlocking positions.

Patent CA-2158533-A1 (CA)
Title: Drill bit having improved cutting structure with varying diamond density
Inventor: KEITH CARL W
IPC: E21B10/54
Filed: 1995-09-18
Abstract: A fixed cutter drill bit includes a cutting structure having radially-spaced sets of cutter elements. Each cutter in a set has a cutting profile that, in rotated profile, partially overlaps the cutting profiles of each of the other cutters that are in the same set so as to create a region of maximum diamond density. The region of maximum diamond density in a set is defined such that the centerlines of the cutting profiles of the elements in the set pass through the region of maximum diamond density. The cutting profiles of the spaced sets of cutters also may overlap to create border regions of multiple diamond density. The diamond density of border regions is less than or equal to the density in the region of maximum diamond density. Providing such regions of varying diamond density along the bit face tends to increase the bit's ability to resist vibration and provides an aggressive cutting structure, even after significant wear has occurred.

Title: Current cell for converting a binary value to an analog value
Inventor: MALEK-KHOSRAVI BEHNAM
IPC: H03K17/041
Filed: 1995-10-30
Abstract: A digital value represented by binary signals is converted to a corresponding analog value by three (3) current cells, preferably C-MOS p-type, in a digital-to-analog converter (DAC).  The three (3) transistors, preferably disposed on an integrated circuit chip, comprise (a) an input switch transistor receiving a digital input signal at its gate,  (b) an output transistor providing an output current at its drain and (c) a current bias transistor.  The switch and output transistor sources and the bias transistor drain are common.  The output transistor gate is biased by a substantially constant voltage. The bias transistor source receives a supply voltage through a bonding pad on an integrated circuit chip and a bond wire extending from the pad to a pin on the chip package lead frame.  At low frequencies (e.g. 100 MHz), the wave shape of the output transistor drain current is flat.  At increased frequencies (e.g. 225 MHz), the output current has a spike from a supply voltage spike induced in the bond wire as a result of different magnitudes in the bias transistor current when the switch transistor responds to binary signals.  A circuit compensates for the different current magnitudes in the bias transistor.  The compensating circuit may include fourth and fifth transistors respectively corresponding to the current and input transistors to produce through the bond wire a current, with the input transistor non-conductive, corresponding to the current in such wire when the input transistor is conductive.
