Filed:

Feb 12, 2001

Appl. No.:

09/781602

Inventors:

John A. Simonetti - Thousand Oaks CA
David H. Hopkins - Escondido CA

Assignee:

PTI Advanced Filtration, Inc. - Oxnard CA

International Classification:

D06B 512

US Classification:

68 191, 68 20, 68202

Abstract:

The present invention is directed to a system and method for removing a first chemical from a web of filtration membrane material using a vacuum roller or other vacuum pressure application device. Embodiments of the method involve applying vacuum pressure to a surface of the membrane web, immersing said membrane web in a flushing chemical and removing the membrane web from the flushing chemical. Embodiments of the system may include one or more vacuum rollers, positioning rollers and a flushing chemical in which a portion of the membrane web may be immersed.

Matthew J. Mount - Long Beach CA
David G. Hopkins - Riverside CA

Assignee:

Union Oil Company of California - Los Angeles CA

International Classification:

E21B 1500

US Classification:

175122

Abstract:

A measured and controlled tension is applied to one or more lines or cables attached to a drilling rig. Preferably, the tensioned line provide reactive torque support for the power swivel, The controlled tension allows a greater power swivel torque to be used on existing drilling rig structures and better distributes any portion of the torque load reacted by the structure. The controlled tension system can also be integrated into a fail-safe control system, where sensed cable failure or excessive cable loads cause a safe shutdown of operations, or the measured tension may also be based to control other drilling operations, such as hoisting speeds.

International Classification:

H04N 5/232
G06Q 10/06

Abstract:

There is disclosed a system, apparatus and methods for optimizing photo selection. When a photographer takes photos as requested in a shot list, the photos are automatically assigned a quality score which correlates to how prominently the photo would be displayed in an online search. The photos and the quality scores are displayed to the photographer so that when the photographer has shot a sufficiently high quality photo then the photographer can stop shooting. Photos with the highest quality scores are optimal. The shot lists include reference photos, and if a new photo has a higher quality score than the corresponding reference photo, the new photo becomes the reference photo.

David Hopkins - Santa Monica CA, US

International Classification:

H04W 4/021
H04W 4/21
H04L 29/08

Abstract:

There is disclosed herein a non-volatile machine-readable medium storing a program, a system and method for enabling proximity-based, peer-to-peer sharing of media in which a first device having a wireless communication surrounding the device detects other wireless devices within the region. Communication connections are formed between the wireless devices and a list of the authenticated connections is maintained. Without input from a user, media is shared between the individual devices on the authenticated connections list and a remote server, subject to permissions pre-set by the individual devices. Devices not included in the list of authenticated connections are blocked from accessing the media. Access to the media is available for a period of time, after which time access to the media is blocked for all devices.

Inventors:

- Santa Monica CA, US
David Hopkins - Santa Monica CA, US
Ryan Rifkin - Los Angeles CA, US

International Classification:

H04W 4/021
H04W 4/21
H04L 29/08

Abstract:

There is disclosed herein a system and method for enabling access to media. The method includes receiving media and a media location indicating a location from which the media was shared, storing the media in conjunction with a geofence area defined by the media location plus a pre-determined area around the media location, receiving a request for any media from a device along with a device location indicating a location of the device making the request, and comparing the device location with the geofence area and, when the device location is within the geofence area, providing access to the media, and when the device location is outside of the geofence area, denying access to the media.
