Adaptive Controller For Pc Cooling Fans
US Patent:
7138781, Nov 21, 2006
Filed:
Nov 23, 2005
Appl. No.:
11/286529
Inventors:
David C. Murray - Austin TX, US
Dennis O'Brien - Austin TX, US
Randy B. Goldberg - Farmingdale NY, US

Assignee:
Standard Microsystems Corporation - Hauppauge NY
International Classification:
G05B 11/42
US Classification:
318610, 318811, 318599, 318254, 318600, 318609
Abstract:
A system and method for controlling a fan is disclosed. In one embodiment, a fan controller is integrated in silicon and uses an embedded microcontroller to implement a digital fan control algorithm. The microcontroller may continually monitor temperature and sample the speed of the controlled fan. The speed of the fan may be compared to RPM values fitted on a desired curve that is representative of the Temperature-versus-RPM function for the given controlled fan. The fan control algorithm may be based on a PID compensator or a Ramp Rate Closed-loop controller (RRCC), which may be operated to drive the fan to the desired speed. The fan may also provide a Fan ID feedback signal to the microcontroller, which may use the Fan ID feedback signal upon system start-up to initialize the PID compensator gain settings or the RRCC parameter settings, and select the appropriate Temperature-versus-RPM function curve based on pre-determined values for the given fan. Thus, fans from different vendors may be changed at the factory without having to perform configuration programming. The need for a PWM command may be obviated, thereby facilitating the removal of any associated circuitry from the given fan, and thus reducing the cost of the fan.

Hardened Data Recording System For Drilling Rigs And Other Drilling Equipment
US Patent:
2012009, Apr 26, 2012
Filed:
Oct 17, 2011
Appl. No.:
13/274500
Inventors:
David Carl Murray - Austin TX, US
Ted Louis Christiansen - Houston TX, US
Ted Louis Christiansen - Houston TX, US
Assignee:
NATIONAL OILWELL VARCO, L.P. - Houston TX
International Classification:
F16M 13/02, G06F 17/40
US Classification:
248550, 702 9
Abstract:
A system for recording data associated with a drilling rig is disclosed. In one embodiment, such a system includes one or more hardened memory devices and a memory interface unit to receive one or more data streams containing drilling data. The memory interface unit is configured to extract the drilling data from the data streams and store the drilling data on the one or more hardened memory devices. If desired, the hardened memory devices may be distributed across a drilling rig to increase the probability that recorded data will survive a catastrophic event. Optionally, the system includes a communication device to enable communication with a remote site.
