Patent number: 9295417Abstract: Systems and methods for delivering to and/or receiving fluids or other materials, such as blood or interstitial fluid, from subjects, e.g., from the skin. Beading disruptors and/or capillaries may be used for facilitating the transport of fluids from a subject into a device. Beading disruptors may disrupt the “pooling” of bodily fluids such as blood on the surface of the skin and help influence flow in a desired way. A capillary may conduct flow of fluid in the device, e.g., to an inlet of a channel or other flow path that leads to a storage chamber. A vacuum (reduced pressure relative to ambient) may be used to receive fluid into the device, e.g., by using relatively low pressure to draw fluid into the inlet of a channel leading to a storage chamber. The vacuum source may be part of the device.Type: GrantFiled: April 26, 2012Date of Patent: March 29, 2016Assignee: Seventh Sense Biosystems, Inc.Inventors: Ramin Haghgooie, Donald E. Chickering, III, Shawn Davis, Mark Michelman, Li Yang Chu

Publication number: 20160038068Abstract: The present invention generally relates to systems and methods for delivering and/or receiving a substance or substances such as blood, from subjects, e.g., to the skin and/or from the skin. In one aspect, the present invention is generally directed to devices and methods for receiving blood from a subject, e.g., from the skin, using devices including a substance transfer component (which may contain, for example, one or more microneedles), and a storage chamber having an internal pressure less than atmospheric pressure prior to receiving blood. In certain embodiments, substances may be received from and/or delivered to the subject with relatively little pain. The pain may be assessed, for example, using pain scales such as the Wong-Baker FACES Pain Scale. In some cases, the device may be self-contained, and in certain instances, the device can be applied to the skin, and activated to receive blood from the subject.Type: ApplicationFiled: April 17, 2015Publication date: February 11, 2016Applicant: Seventh Sense Biosystems, Inc.Inventors: Donald E. Chickering, III, Howard Bernstein, Shawn Davis, Ramin Haghgooie, Douglas A. Levinson, Mark Michelman, Ping Gong

Patent number: 9253533Abstract: Technology is described for identifying a scene in video content. Video content to be played on a device may be provided. A segment of the video content that includes an occurrence of an interest event may be identified, the segment being identified based on instructions received while the video content is being provided to the device. A scene may be created with the segment based on a starting time code of the interest event. The scene with the segment may be provided for playback.Type: GrantFiled: March 22, 2013Date of Patent: February 2, 2016Assignee: Amazon Technologies, Inc.Inventors: Mark Glyn Morgan, Wesley Shawn Davis, Charles Benjamin Franklin Waggoner

Patent number: 9215268Abstract: Embodiments may include the generation and use of content source rankings for improving playback quality of content streams. In embodiments, a merchant system may collect and aggregate multiple quality metrics for different content streams that various content sources provide to various clients. The merchant system may utilize the quality metrics to generate rankings of content sources for clients. In some cases, a client itself may generate a ranking of content sources for use in the selection of content sources. The merchant system may provide such rankings to clients to improve the content stream playback experience on the client. For instance, at content acquisition time, a client may request a content stream from a content resource ranked highest on a content source ranking provided by the merchant. If the content stream degrades, the client may source subsequent portions of the content stream from another highly ranked content source of the ranking.Type: GrantFiled: March 18, 2011Date of Patent: December 15, 2015Assignee: Amazon Technologies, Inc.Inventors: James H. Wood, James Marvin Freeman, II, Wesley Shawn Davis, Jinesh U. Vora

Publication number: 20150320349Abstract: In some embodiments, the present invention generally relates to the separation of blood within a device to form plasma or serum. In some embodiments, the present invention generally relates to the removal of fluids, such as blood, contained within a device. In one aspect, the present invention is generally directed to systems and methods for receiving blood from a subject and processing the blood to form plasma or serum. For example, a device may be applied to the skin of a subject to receive blood from the subject and pass the blood through a separation membrane, which separates the blood into plasma and a portion concentrated in blood cells. As another example, blood or plasma may be allowed to clot within the device and serum (the unclotted portion of the blood) may be withdrawn from the device. The device may contain, in some cases, a vacuum source such as a pre-packaged vacuum to facilitate receiving of blood and/or passage of the blood through the separation membrane to produce plasma or serum.Type: ApplicationFiled: July 22, 2015Publication date: November 12, 2015Applicant: Seventh Sense Biosystems, Inc.Inventors: Ramin Haghgooie, Donald E.

Publication number: 20150313522Abstract: The present invention generally relates to devices and techniques associated with diagnostics, therapies, and other applications, including skin-associated applications, for example, devices for delivering and/or withdrawing fluid from subjects, e.g., through the skin. In some embodiments, the device includes a system for accessing an extractable medium from and/or through the skin of the subject at an access site, and a pressure regulator supported by a support structure, able to create a pressure differential across the skin at at least a portion of the access site. The device may also include, in some cases, a sensor supported by the support structure for determining at least one condition of the extractable medium from the subject, and optionally a signal generator supported by the support structure for generating a signal relating to the condition of the medium determined by the sensor.Type: ApplicationFiled: July 13, 2015Publication date: November 5, 2015Applicant: Seventh Sense Biosystems, Inc.Inventors: Howard Bernstein, Donald E.
