Patent number: 7102527Abstract: A passenger detection system is provided. The passenger detection system utilized an oscillation circuit that causes an antenna electrode to emit an electric field that is disrupted by the electrical characteristics of n object placed on the seat. This disruption alters the current and phase of the signal in the antenna electrode. By comparing the current flowing in the antenna electrode and/or the difference between the phases of the signal is the antenna electrode and the oscillation circuit output signal with predetermined threshold values, it is possible to detect the presence of a passenger in a reliable and inexpensive manner. Environmental sensors are used to make the determination more accurate. Humidity, moisture and/or grounding condition are detected and used to alter processing, values or calculations.Type: GrantFiled: April 16, 2004Date of Patent: September 5, 2006Assignee: Elesys North America Inc.Inventors: Shiuh-An Shieh, Gregory T. Thompson

Patent number: 6977351Abstract: A rain sensor for use with an irrigation control system includes a position sensing element. A moisture absorptive element is supported for receiving rainfall. An actuating element is mechanically connected to the moisture absorptive element for movement adjacent the position sensing element as the moisture absorptive element expands and contracts to thereby induce a change in the position sensing element that can be used to generate an interrupt signal without any mechanical connection between the moisture absorptive element and the position sensing element.Type: GrantFiled: October 29, 2004Date of Patent: December 20, 2005Assignee: Hunter Industries, Inc.Inventor: Peter J. Woytowitz

Patent number: 6853305Abstract: A tape-drive condensation sensor includes a probe with first and second spaced-apart electrodes that define a passage for air flow within a pneumatic conduit. A voltage source is coupled between the electrodes and the voltage of the source and the spacing between the electrodes are adapted to pass a current when a drop of condensation forms between the electrodes. An alarm circuit is activated by the flow of current, the alarm being adapted to signal an event of discernible condensation.Type: GrantFiled: May 28, 2002Date of Patent: February 8, 2005Assignee: International Business Machines CorporationInventors: Mariel Acosta-Geraldino, Diana Joyce Hellman, Wayne Alan McKinley

Patent number: 6841745Abstract: A battery device has a plurality of batteries connected in series. Each of the batteries includes a thermally responsive switch, a first conductive plate connected to a first terminal of the thermally responsive switch, a second conductive plate connected to a common terminal of the thermally responsive switch, and a third conductive plate which functions as a bypass when it is connected to a second terminal of the thermally responsive switch. In normal operation, the thermally responsive switch is in contact with the first fixed contact of the movable contact such that the first and second conductive plates are electrically connected. When the battery heats up abnormally, exceeding a maximum permissible temperature, the bimetal strip is inverted such that the movable contact comes into contact with the second fixed contact and thus the second and third conductive plates become electrically connected.Type: GrantFiled: October 6, 2003Date of Patent: January 11, 2005Assignee: ALPS Electric Co., Ltd.Inventor: Makito Takigawa

Patent number: 6570109Abstract: A micro-switch is mounted within a housing and is electrically connectable to an irrigation controller. The switch has a spring biased actuating lever pivotable between ON and OFF positions. A single disc made of a hygroscopic material is mounted within the housing adjacent the inner end of the lever for absorbing rainfall and rapidly expanding a sufficient amount to move the actuating lever from its ON position to its OFF position to thereby cause the watering program of the irrigation controller to be interrupted. A stack of moisture absorptive discs made of the same hygroscopic material is mounted in the housing adjacent an outer end of the lever. When the stack of discs receives rainfall it slowly expands and maintains the actuating lever in its OFF position after the single hygroscopic disc has dried and contracted to ensure that watering is not re-initiated too soon after a storm.Type: GrantFiled: October 26, 2001Date of Patent: May 27, 2003Assignee: Hunter Industries, Inc.Inventors: Paul A. Klinefelter, Barbara A. Coppola, Craig S. Gardner, Philip H. Warren, Jr.

A sensitivity control device for controlling sensitivity of the standing water detector for humidity, or dampness, level and for detecting a standing water leak; the sensitivity control device being in communication with the induced current amplifier. A latching relay driver connected to the sensitivity control device with the latching relay driver being able to memorize a leak condition when electrical power is lost. A control rectifier driven by the latching relay driver, with the control rectifier driving a 120-volt AC line voltage load.Type: GrantFiled: October 15, 2001Date of Patent: December 3, 2002Inventor: Steven P.
