Publication number: 20130060232Abstract: An automatic mixing device, an actuating device removably mounted to the automatic mixing device and a retractable syringe having the automatic mixing device are provided. The actuating device has an initially compressed spring and a trigger member that initiates spring decompression to drive depression of a mixing plunger of the automatic mixing device. A seal located in the outer chamber is capable of axial movement upon depression of the mixing plunger, from a first position in sealing engagement with one or more apertures in an inner barrel to a second position intermediate the apertures and vents in an outer barrel. This allows depression of the mixing plunger to force a first substance from the outer chamber through the apertures to mix with a second substance in an inner chamber of the inner barrel. The mixed substance in the inner barrel is then delivered by the syringe with subsequent needle retraction.Type: ApplicationFiled: August 30, 2012Publication date: March 7, 2013Applicant: UNITRACT SYRINGE PTY LTDInventors: Katlin M. Adlon, Philip A. Weaver, Peter J. Dungar

Publication number: 20130035664Abstract: A mixing device and a retractable syringe comprising same are provided. The mixing device comprises concentric outer and inner barrels that form an outer chamber, the inner barrel having an inner chamber. A mixing plunger is slidably located in the outer chamber. A seal located in the outer chamber is capable of axial movement, in response to depression of the mixing plunger, from a first position in sealing engagement with one or more apertures in the inner barrel to a second position intermediate the apertures and vents in the outer barrel. This allows depression of the mixing plunger to force a first substance from the outer chamber through the apertures to mix with a second substance in the inner chamber. The mixed substance in the inner barrel is then delivered by the syringe with subsequent needle retraction.Type: ApplicationFiled: August 3, 2012Publication date: February 7, 2013Applicant: UNITRACT SYRINGE PTY LTDInventors: Ramin Mojdehbakhsh, Peter J.

Patent number: 8110757Abstract: An apparatus and a method for determining the location of a pointing device in the vicinity of a set of receivers able to receive one or more locating signals transmitted through a medium. The method includes receiving at a receiver a signal that includes a locating signal and an interfering signal, determining an estimated interference signal indicative of the interfering signal included in the signal received, determining a signal indicative of the difference between the received signal and the estimated interference signal, and using the signal indicative of the difference to compute the location of the pointing device on a surface near the set of receivers. One version uses a separate receiver from which to determine the estimated interference signal, while another version uses the received signal at a time when there is expected to be no locating signal present in order to determine the estimated interference signal. An adaptive filter computes the estimated interference signal.Type: GrantFiled: July 14, 2008Date of Patent: February 7, 2012Assignee: Luidia Inc.Inventors: Philip A. Weaver, Xiang Zhu

Patent number: 5995487Abstract: Method and apparatus for enhancing the ability of a subscriber to connect to a carrier network by enabling the service provider to indicate to the subscriber when a requested connection to the carrier network would utilize unguaranteed bandwidth and, absent objection by the subscriber, to complete the requested connection utilizing the unguaranteed bandwidth. Upon receipt of a request for set-up of a call of an indicated bandwidth, the service provider will acknowledge the call set-up request. The service provider will then issue a call proceeding message to indicate that the requested connection is being arranged. The call proceeding message will contain an unguaranteed bandwidth indicator if the carrier network cannot guarantee the requested bandwidth. If a cancellation of the call request is not received in response to the unguaranteed bandwidth indicator, the call will be completed.Type: GrantFiled: August 6, 1997Date of Patent: November 30, 1999Assignee: Northern Telecom LimitedInventors: Philip A.
