Title: Directory assistance call processing systems and related methods
Inventor: MARGIOTTA VINCE SCOTT
IPC: H04Q3/00
Filed: 1997-08-14
Granted: 2000-06-27
Abstract: In a telecommunications switching system, after a non-published listing has been located in response to a request from a calling customer station and after the calling customer has been qualified, a connection is set up between the calling customer station and a customer station identified by the listing. Qualified callers are those callers who satisfy at least one specified condition or criterion. Illustratively, the condition specified may be that the call must be placed from a telephone located within a geographic region from which the customer station identified by the listing is willing to accept calls. Alternatively, where the customer station identified by the listing is a cellular telephone, the condition may be that the calling customer accepts all charges associated with the cellular communication link. The directory assistance call is completed without announcing the non-published number to the calling customer.

Granted: 2003-11-04
Abstract: A cover for the cargo area of a vehicle includes two rails secured to opposite sides of the cargo area of the vehicle.          A cover material is bounded by four peripheral rails.  Two of the rails have the same cross-section and are located on two sides of the cover material.   The other two rails are of a different configuration and are located on other two sides of the cover.  A biasing member, such as a-torsion bar, is inserted into the ends of each of the rails secured to the vehicle bed.  The opposite end of the torsion bar is located in and slides within a cylinder.  The opposite end of the cylinder includes a slide member.  The slide members are located in channels formed in two of the rails.  In the closed position, latches engage the torsion bars and hold the cover in place.  To open the cover, two of the latches are disengaged, thereby allowing the cover to rise in response to the force of the biasing members.   The cover pivots about a hinge formed by the engagement of the secured latches with the torsion bars.

Granted: 2003-04-01
Abstract: A voltage detection circuit 2 detects a voltage of a battery 1 and, when the voltage thus detected is within a tolerable input voltage of a power source unit 5, an on/off signal transmitter circuit 4 allows an on/off signal generator circuit 3 to transmit an on/off signal S2 to the power source unit 5. When the voltage of the battery 1 becomes lower than a lower limit of the tolerable input voltage range of the power source unit 5 due to increase of a power consumption of a load 6 thereof, the on/off signal transmitter circuit 4 transmits an off signal S3 to the power source unit 5 regardless of the on/off signal S2 from the on/off signal generator circuit 3 . Thus, it is possible to prevent an erroneous operation of the load due to abnormal operation of the power source unit.

Title: Contractible sanitary napkin
Inventor: DI CINTIO ACHILLE
IPC: A61F13/15
Filed: 1997-04-11
Granted: 2003-08-19
Abstract: The present invention relates to absorbent articles, particularly sanitary napkins or panty liners, made for joining to the undergarment of a wearer. Such articles are typically joined to the undergarment of a wearer while the wearer has the undergarment stretched between the legs. In this stretched position, the undergarment has an extended surface. Upon pulling the undergarment up into the wearing position, the undergarment retracts and thereby causes the attached absorbent article also to retract. According to the present invention, the absorbent articles are rendered contractible at least in one of the directions of retraction of the undergarment to reduce wrinkling or folding of the absorbent article.

Title: Method for calibrating the initial position and the orientation of one or several mobile cameras
Inventor: ARNOUL PATRICK
IPC: G06T7/00
Filed: 1998-10-23
Granted: 2011-12-20
Abstract: The invention concerns a method for calibrating a camera (4, 22) arranged on a mobile support (21), wherein the camera takes a test object image formed of at least three marks appearing in the camera field, and the analysis of said image gives the initial position and orientation of the camera relative to that of the test object image, known in an application. The support (21) can then be displaced towards an object (28) whereof the camera takes images. Since the support displacements are accurately measured, the analysis of the object images gives the accurate position and orientation of the object relative to the camera and relative to the test object. One application consists in the survey of road signs (28) for constituting databases for managing a network or for an on-board navigation system.

Abstract: The present invention provides a glass fusing method comprising the steps of preheating contacting or close portions of glass pieces to a temperature which is lower than a fusing temperature of the glass, then locally heating the portions to a temperature which is equal to or higher than the fusing temperature of the glass and fusing the portions after the preheating step, and annealing the fused portions to a temperature which is lower than the fusing temperature of the glass after the fusing step. The fusing method is carried out as follows, for example. More specifically, a laser beam is supplied from a laser oscillator (10) to a torch head (8), and the laser beam supplied from the torch head (8) is irradiated as irradiated light (80) on portions of glass plates (A) and (B) to be fused together. The torch head (8) circulates around peripheral edge portions of the glass plates (A) and (B) three times while changing a heating level of the irradiated light (80). Preheating, fusion and annealing are performed for first, second and third circulations, respectively.
