Publication number: 20240060801Abstract: An actuator apparatus includes an actuator rod with a interior cavity and a set of rod holes extending through the actuator rod to the cavity. The apparatus includes a light assembly positioned to light the cavity and an actuator block with an opening sized to conform to an outer surface of the actuator rod and one or more block holes in the opening. Each of the block holes is positioned to align with each of the rod holes as the actuator rod moves with respect to the actuator block. The actuator block includes a light sensor positioned to sense light coming through a rod hole aligned with the block hole. The apparatus includes a verification module with a light modulator that modulates light of the light assembly to transmit a position signal, and a verification circuit that transmits a verification signal after the light sensor receives the position signal.Type: ApplicationFiled: October 31, 2023Publication date: February 22, 2024Inventors: David Dahl, David E.

Publication number: 20210309408Abstract: A container for liquids that allows the contents to be emptied out quickly without spattering or gurgling. A sealed closure within the neck of the container can be opened by pulling a ring on the bottom of the container to open both an air inlet in the bottom of the container and the closure in the neck of the container. A connecting rod within the container opens the closure in the neck of the container in response to opening of the air inlet closure at the bottom of the container, to allow the contents of the container to flow out through the neck, while air enters into the container through the opening at the bottom of the container.Type: ApplicationFiled: April 3, 2020Publication date: October 7, 2021Inventor: David Dahl

Patent number: 9877672Abstract: A device (1) is provided that is configured to indicate the presence or absence of one or more biological entities in a biological sample. The device comprises a sampling portion (11), the sampling portion comprising flexible material adjustably conformable to a part of a human or animal body, at least a portion of the sampling portion being absorbent and configured to receive a biological sample directly from the body; and a test portion (12) in fluid engagement with the sampling portion, the test portion comprising one or more test zones (14). The sampling portion and test portion are configured such that at least a portion of the sample received by the sampling portion is transferable to the test portion such as to contact one or more of the test zones, and wherein each test zone is configured to indicate the presence or absence of one or more biological entities in the sample.Type: GrantFiled: January 27, 2011Date of Patent: January 30, 2018Assignee: Ellume Pty LtdInventors: Steven David Dahl, Sean Andrew Parsons, Jennifer Maschmann, Kon Euan Gerard Wong, Tim Ian Spink, Stephen Robert Wilson

Patent number: 9413807Abstract: A method dynamically assigns tasks for visually presenting data. A server receives a request, from a client device, to display a visual representation of data in a designated format. The request specifies one or more client device characteristics, including: client memory capacity; current client memory utilization; client processor capability; current client processor utilization; and the client's web browser. The server determines whether to render the requested visual representation at the server or at the client device based on several factors, including the client device characteristics and the size of the data set. When rendering at the client, the server sends the requested data to the client, including data necessary to render the visual representation in the designated format. Otherwise, the server renders the requested visual representation according to the designated format using the data, and sends the rendered image to the client.Type: GrantFiled: October 15, 2013Date of Patent: August 9, 2016Assignee: TABLEAU SOFTWARE, INC.Inventors: Scott Sherman, James Baker, Lu Sien Tan, Justin Frederick Rockwood, Jason Scott King, Daniel Philip Cory, Stephen Howard Pellegrin, Austin David Dahl
