Lift Truck Active Load Stabilizer
US Patent:
2005010, May 12, 2005
Filed:
Sep 23, 2003
Appl. No.:
10/668571
Inventors:
Mark Patterson - Beavercreek OH, US
International Classification:
G06G007/00
US Classification:
701050000
Abstract:
A lift truck having an acceleration sensor and a feedback control system for automatically adjusting the tilt angle of the load supporting surface relative to the lift truck during lift truck operation. The control system maintains the load supporting surface substantially perpendicular to the direction of the resultant of the gravitational force vector and the travel acceleration force vector. The sensor is mounted to the mast for sensing the direction of the resultant vector and is connected as the feedback element of the control system. A controller stores a reference input comprising a stored value of angular direction representing the angular direction of the resultant vector when the lift truck is at rest and the cargo support fork is horizontal. The deviation or error of the control system is the difference between the stored vector direction and the sensed vector direction of the resultant of the two accelerations. The controlled element of the feedback control system, to which the control system output is connected, is the mast tilt actuator of the lift truck. The mast tilt angle relative to the lift truck is controllably varied to bring the currently sensed resultant angular direction into alignment with the stored reference angular direction.
Passive Wireless Sensors For Chemical And Biological Agents And Wireless Systems Including The Passive Wireless Sensors
US Patent:
2014006, Mar 6, 2014
Filed:
Jul 24, 2013
Appl. No.:
13/949907
Inventors:
Mark Alan Patterson - Beavercreek OH, US
International Classification:
G06K 7/10
US Classification:
340 101
Abstract:
Wireless sensors for detection of an analyte may include a sensor receiving antenna configured to receive interrogation pulses having an interrogation frequency, a DC converter, a relaxation oscillator circuit electrically, and a sensor transmitting antenna. The relaxation oscillator circuit may include a capacitance element that defines a response-pulse frequency of the wireless sensor. The capacitance element may include an interdigitated capacitor coated with a detection layer of a functional material having a dielectric constant that defines the dielectric constant of the interdigitated capacitor. This dielectric constant changes when the functional material is exposed to the analyte, thereby changing the response-pulse frequency of the relaxation oscillator circuit to an analyte-exposure frequency indicative of the exposure of the functional material to the analyte. Wireless systems for detecting an analyte may include a wireless sensor that communicates with an interrogation module.
