Patent number: 11806711Abstract: Various fluidic structures are described that may be implemented between two portions of material, at least one of which may be made of a flexible but inelastic material, such as Mylar. Such fluidic circuits may be configured such that applying a clamping pressure zone to such fluidic circuits and then moving the clamping pressure zone along the fluidic circuit and along a particular axis may cause the fluidic circuit to operate in a particular manner, thereby driving fluids contained within the fluidic circuit around the fluidic circuit according to a desired flow sequence.Type: GrantFiled: January 12, 2022Date of Patent: November 7, 2023Assignee: Hound Labs, Inc.Inventors: Daniel H.

Patent number: 11533392Abstract: Provided is a solid-state illumination system for use in a microscopy system utilizing a light sensor of a mobile phone camera module. The system includes a bright-field illumination source with an array of light-emitting diodes (LEDs). The array of LEDs is configured to produce transmission light within a range of view of the light sensor of the mobile phone camera module. The system also includes a dark-field illumination source including a ring of LEDs. The ring of LEDs is configured to produce light outside of the range of collection of the camera module lens. The system also includes a diffuser configured to diffuse the transmission light and a diffusive black material coupled to the diffuser. The diffusive black material is configured to pass through at least some of the transmission light while blocking reflections of the scattering light.Type: GrantFiled: May 6, 2021Date of Patent: December 20, 2022Assignee: Hound Labs, Inc.Inventors: Daniel H.

Patent number: 9709581Abstract: Various embodiments for a hand-held device to determine a level of one or more cannabinoid compounds in exhaled human breath are provided; some embodiments may also determine a level of alcohol in the exhaled breath. The device may perform any of the following steps: capture, concentrate, separate, identify, and quantify the level of cannabinoids in the exhaled human breath. The device may use solvent extraction and liquid chromatography to concentrate and separate cannabinoids from breath contaminants, followed by selective chemical modification of the cannabinoids with a fluorescent indicator for quantification. The measurement methodology may also include real time calibration of the device and detection protocol using known cannabinoid standards, which are simultaneously analyzed along with an unknown, to quantify the level of cannabinoids captured from the breath sample.Type: GrantFiled: April 29, 2016Date of Patent: July 18, 2017Assignee: Hound Labs, Inc.Inventors: Michael J. Gordon, Louis Chin Jones, Michael Scott Lynn
