Patent number: 8743689Abstract: In order to ameliorate the overload at an overloaded network node that is discarding some of the SMSs it is receiving, when a node is overloaded with received SMSs, it sends a message to the nodes from which it is receiving SMSs of that fact and includes a parameter indicating the extent to which it is overloaded. That parameter, for instance, may be the percentage of SMSs that it is receiving that are being discarded. With this information, the sending node can determine a percentage of the pending SMSs during such conditions that will help remove the overloaded node from the overload condition more quickly. Furthermore, the network protocol may be adapted to include a priority parameter in SMSs. Then, when an SMS sending node knows that a node to which it is sending SMSs is overloaded, the sending node may decide which SMSs to send to the overloaded node based on such priority information.Type: GrantFiled: February 9, 2010Date of Patent: June 3, 2014Assignee: Apple Inc.Inventor: Gary Boyd Stephens

Publication number: 20060062499Abstract: A pressurized hydrodynamic bearing and seal assembly for radial and/or thrust bearings includes a stationary bearing member formed of a carbon/graphite material positioned adjacent a rotating member so as to define a space between the members when the respective bearing segments are rotating with respect to each other. In one form, the carbon/graphite is positioned in the outer stationary position and the inner member is fixed to a rotating shaft. The inner member may be formed of a metallic material or a ceramic or ceramic composite. The operation of the bearing is improved by including a seal dam along an axial end of the stationary carbon/graphite member so as to prevent leakage of gases accumulating between the inner and outer members. In this form, the gas pressure can be increased substantially so as to increase the load capacity of the bearing. The system also includes a thrust bearing of substantially the same type of construction but oriented to absorb the thrust motion.Type: ApplicationFiled: April 6, 2005Publication date: March 23, 2006Inventor: Gary Boyd

Publication number: 20050185277Abstract: An illumination system for a reflective display is particularly useful for microdisplays that use reflective displays. The light source and the reflective image display unit are mounted in a coplanar manner, thus permitting the light source and the display unit to be mounted on a single board, or even on a single substrate. The display unit may include a first light source directing light generally along a first axis and a reflective image display unit disposed with an optical axis substantially parallel to the first axis. A reflective polarizing film is disposed to direct light from the first light source to the reflective image light display unit.Type: ApplicationFiled: March 2, 2005Publication date: August 25, 2005Inventors: Gary Boyd, Richard Miller, Leland Whitney

Patent number: 6600920Abstract: A system for delivering a call to a mobile unit in a wireless network includes a mobile switching center that receives a call setup request message initiated in response to a request from an originating mobile switching center. The receiving mobile switching center initiates setting up the call between the receiving mobile switching center and the mobile unit before the call is setup between the receiving mobile switching center and the originating mobile switching center. Preferably, the receiving mobile switching center initiates setting up the call by issuing a page in response to receiving the call setup message.Type: GrantFiled: May 28, 1999Date of Patent: July 29, 2003Assignee: Nortel Networks LimitedInventors: Gary Boyd Stephens, Andrew Silver

Patent number: 6256503Abstract: A method and system in a wireless communications network are provided for restricting communication transactions based on the geographic location of originators and terminators within the wireless communications network. First, a communications transaction is initiated. In response to an initiation of the communications transaction, a geographic location of an originator of the communications transaction is determined. In response to determining the geographic location of the originator, a geographic location of a terminator of the communications transaction is determined. The geographic location of the originator is thereafter automatically compared to the geographic location of the terminator. The communications transaction is completed based upon a selected proximity of the geographic location of the originator to the geographic location of the terminator.Type: GrantFiled: July 9, 1997Date of Patent: July 3, 2001Assignee: Nortel Networks LimitedInventor: Gary Boyd Stephens

Patent number: 6151505Abstract: A system and method of providing a terminator telecommunications unit with the geographic location of a mobile telecommunications unit, where the terminator unit may then provide directions to the mobile unit in voice format or non-voice data format so the mobile unit can use the directions to arrive at the location of the terminator unit.Type: GrantFiled: July 3, 1997Date of Patent: November 21, 2000Assignee: Northern Telecom LimitedInventors: John Pruett Larkins, Gary Boyd Stephens

Patent number: 6091957Abstract: A system and method is described herein which provides an originating telecommunications unit with the geographic location of a mobile telecommunications unit without actually placing a call to, or receiving a call from, the mobile unit. The originating unit provides a service platform with an authorization code and the telephone number, or other identification, of the mobile unit to be located. The service platform then initiates a location program which uses various geographic location methods to provide the originating unit with the location of the mobile unit, without the user of the mobile unit becoming aware that the location of the mobile unit is being determined.Type: GrantFiled: June 12, 1997Date of Patent: July 18, 2000Assignee: Northern Telecom LimitedInventors: John Pruett Larkins, Gary Boyd Stephens

Patent number: 5995823Abstract: A method and system in a wireless communications network for restricting certain communication transactions to specific geographic areas in order to reduce the risk of communications fraud are presented. Initially, a list of communication transactions is stored such that the list includes communication transactions permitted to occur at each of a number of geographic locations. Thereafter, a communications transaction is initiated. In response to an initiation of the communications transaction, a geographic location of an originator of the communications transaction is determined. Next, the list of communication transactions is automatically scanned for communication transactions permitted to occur at the geographic location. If the communications transaction is not found among the list, the initiation of the communications transaction is thereafter terminated. Alternatively, if the communications transaction is found among the list, the communications transaction is thereafter permitted to continue.Type: GrantFiled: July 9, 1997Date of Patent: November 30, 1999Assignee: Nortel Networks CorporationInventor: Gary Boyd Stephens
