Title: Video driver for accommodating multiple video controllers
Inventor: BIGGS KENT E
IPC: G09G5/14
Filed: 1995-04-27
Abstract: A method and system for accommodating multiple video controllers.  The method includes communicating a plurality of primitive commands to a video controller having a configuration of a predetermined type.  Further, the method includes electronically determining the type of the configuration, and generating a vector table comprising a plurality of device-specific routines.  Each entry in the vector table may point to a device-specific routine for hardware acceleration of a primitive command or to a default routine which sets the video controller in a specific mode which can be operated by a set of colordepth-specific routines which operate on any video controller set to the specific mode.  In response to a primitive from the operating environment, common code, which is device and colordepth independent, will access a routine via the vector table.  If the vector table does not access a hardware accelerated routine, colordepth specific code is used to execute the primitive.

Patent CA-2163658-A1 (CA)
Inventor: PETERSON MICHAEL G
IPC: C12Q1/6811
Filed: 1995-04-25
Abstract: Pharmacological agents active at the level of gene transcription are identified in high throughput drug screening assays. The methods involve combining a labeled transcription factor, a nucleic acid coupled to a ligand, a candidate pharmacological agent and a receptor immobilized on a solid substrate, such as a microtiter plate, filter, or bead. The nucleic acid has at least that portion of a nucleotide sequence naturally involved in the regulation of the transcription of the gene which is necessary for sequence-specific interaction with the transcription factor. The resultant combination is incubated under conditions whereby the receptor is bound to the ligand and, but for the presence of said candidate pharmacological agent, the transcription factor is sequence-specifically bound to the nucleic acid. Unbound transcription factor is then removed or washed from the solid substrate and labelled, sequence-specifically bound transcription factor is detected. Incubates which include candidate agents which alter transcription factor binding deviate from control incubates in terms of label signal - typically, binding is disrupted and the signal is diminished. In a preferred embodiment, the entire process is performed by a computer-controllable electromechanical robot with an axial rotatable arm.

Patent CA-2180062-A1 (CA)
Title: Flow regulating valve
Inventor: HAGMANN STEFAN
IPC: G05D7/01
Filed: 1996-06-27
Abstract: A flow regulating valve (1) combines two throttle locations (4, 5; 8, 9 ) in a valve housing (7). One throttle location (8, 9) is always so adjusted that a constant differential pressure prevails across the other throttle location (4, 5). Therefore at that second throttle location (4, 5) the through flow depends only on the degree of opening and not on the differential pressure. A cone (4) of the throttle location (4, 5) comprises at least two individual portions (22, 23) which are displaceable relative to each other and by the spacing of which the effective cross-section of the throttle location (4, 5) is variable. That provides a through-flow limiting effect which is not in the form of a stroke movement limitation. Therefore the full adjusting range is available for adjusting the flow. This flow regulating valve (1) is suitable for controlling flows of liquids in heating installations.

Title: Apparatus and method for automatic climate control
Inventor: RILEY JOSEPH D
IPC: F24F11/00
Filed: 1995-01-30
Abstract: An apparatus and method for controlling the operation of (HVAC) equipment (80) or other climate control equipment (560). A user can set a user set point (150). The system (20) determines whether the space is occupied at any given time, and if it is, maintains the temperature at the user set point (270) within a predetermined allowed margin. If the space is not occupied (280) and the temperature drifts outside the allowed margin, then tile system allows the temperature to drift to a maximum allowable margin, or to a newly determined margin, whichever is less (290). The newly determined margin is based upon a determination of the maximum temperature margin to which the system can drift and still drive the temperature back substantially to the user set point within a predetermined maximum recovery time. The recovery time is calculated based upon past temperature-vs.-time data stored for previous cycles of drift and drive (320).
