Title: Float-responsive valve with premature closure prevention
Inventor: VAUGHAN DON DOUGLAS
IPC: B01J47/02
Filed: 2004-03-19
Granted: 2012-07-17
Abstract: A float-responsive valve includes a valve actuator that is selectively responsive to operation of a float to move from a first position to a second position in which the valve actuator holds the valve element in its open position. When the valve actuator is in the second position thereof, fluid pressure that would otherwise tend to force the valve element toward its seat is essentially incapable of closing the valve element. Preferably, a force vector applied through a flapper-type valve actuator forms an essentially nonnegative, more preferably generally collinear, angle with a bisector line passing through a pivot axis of the valve actuator and a primary contact point between the valve actuator and the flapper.

Title: Location capable mobile handset
Inventor: DUNN DOUGLAS L
IPC: H04W4/90
Filed: 2004-03-26
Granted: 2011-04-12
Abstract: The location capable mobile handset allows the user to provide a call recipient with the location of an unsuccessful attempted emergency call. In one specific example, the call may be an E911 call to a PSAP dispatcher.  Additionally, the call may be to a towing service, or to a family member or friend to request assistance. The call may be any call that a mobile handset user wants to send location information to the party that has been called.  Returning to the E911 call example, the location information reported to dispatcher can include the location of initial E911 call, current location during a successful E911 call, or ground track information from the initial location to the current location. When an E911 call is unsuccessfully attempted, the mobile handset stores the location of the mobile handset at that time. This information can later be transmitted when the mobile handset is in a coverage area. Additionally, the mobile handset can auto-dial 911 upon entering a service area after an unsuccessful E911 attempt. Alternately the user can be prompted to initiate an E911 call when the mobile handset enters a service area.

Title: Interlock for slider locking pin handle
Inventor: EHRLICH RODNEY P
IPC: B60T17/18
Filed: 2006-01-11
Granted: 2008-09-23
Abstract: An interlock for a slider incorporates a cover that moves between a covered position and an uncovered position. In the covered position, the cover prevents access and movement of a handle for actuating locking pins on the slider. The cover may be pivoted to an uncovered position at which the handle can be actuated. Generally, the handle is pulled away from a trailer frame for the slider to move the locking pins out of holes in the trailer frame. When the cover has moved away from the covered position, the cover actuates a valve member that sets at least one park brake. To release the park brakes, the cover must be moved back to the covered position. The cover cannot be moved back to the covered position until the handle is in a position indicative of the locking pins being fully received in the holes in the trailer frame. In this manner, the cover ensures that the locking pins are fully engaged in the trailer frame, and further provides a visual feedback to an operator of why the park brakes may not be released in the event the locking pins are not fully engaged.

Title: Method and apparatus for online contact lens evaluation
Inventor: HEGELS ERNST
IPC: G02C7/04

Granted: 2009-09-22
Abstract: A selectively marked contact lens having, in one aspect, marks in an optical zone region on a surface thereof and, in another aspect, different marks outside an optical zone region of the lens, for an in-vivo lens. With the lens in-vivo, the subject's eye is illuminated and the lens is imaged. A fast algorithm is used to determine the mark coordinates in relation to a measured pupil coordinate to determine position and/or orientation of the contact lens.  A wavefront aberration measurement can also be obtained simultaneously with the contact lens position measurement, as well as pupil size. A fast algorithm provides for online measurements; i.e., at a repetition rate of 10Hz or greater, over a selected time interval. Blinking periods are determined and anomalous lens position and/or wavefront information is discarded. A most frequently occurring wavefront and/or contact lens position/orientation is determined over the selected time interval.
