Event planning using social networking enables an efficient implementation of planning an event, as well as minimizing network traffic and optimizing other technological aspects of life. Additional information acquired by sensors and other technology is able to improve the quality of the event planning. Social network information as well as the additional information is able to be used to select aspects of the event such as time, location, and/or many other aspects of the event.

A sampler for acquiring and transporting sample material may include a sampler body defining a sampling volume configured to hold the sample material. The sampler body may define a sample port that may be used as an entrance to collect the sample material and an exit to expel the sample material. The sample port may be configured to be operably connected to a fluidic channel of a cartridge. The sampler may also define a pump connection port configured to be operably connected to a pump. The pump may force the sample material out of the sampling volume through the sample port.

The invention relates to a combined two-compartment device for diagnosing body liquids, which comprises: (a) an upper compartment for collecting and storing the body liquid; (b) a lower diagnostic compartment for diagnosing the body liquid at a diagnostic stage, said diagnostic compartment comprises a diagnostic strip; (c) an opening at the bottom wall between said upper compartment and said lower compartment, wherein said opening is kept blocked by a suitable valve until just before said diagnostic stage; and (d) a mechanism for releasing said blockage of said opening, thereby to allow flow of the body liquid to said lower compartment, and thereby to come into contact with said diagnostic strip and to affect the diagnostic strip accordingly.

A system for transdermal alcohol sensing to be worn near a skin surface of a user, including: an alcohol sensor; a microporous membrane; a housing coupled to the alcohol sensor and the membrane, defining a volume between the alcohol sensor and a first membrane side, and fluidly isolating the volume from a second membrane side opposing the first membrane side; an electronics subsystem electrically coupled to the alcohol sensor, operable to power and receive signals from the alcohol sensor; and a fastener operable to position the second membrane side proximal the skin surface.

The present invention relates to diagnostic kits and methods based on lateral flow assay devices for detecting the presence or quantity of one or more test analytes within a test sample taken from the skin of a mammal.

Provided herein are epidermal microfluidic systems and methods that allow for the collection of biofluids in a wet or aquatic environment, for example, from the surface of the skin. The described systems allow for the efficient collection of biofluids, without loss of the biofluid to the surrounding environment or introduction of extraneous liquids from the environment. The described microfluidic systems are versatile and can provide information regarding a number of biofluid properties both electronically and colorimetrically/visually.

A method for monitoring intoxication of a user, the method including: receiving a set of samples from a body region of a user; generating an intoxication metric based on the set of samples; and providing a notification to the user based on the intoxication metric. The method can additionally or alternatively include: modifying operation of the transdermal alcohol sensing device based on the intoxication metric; determining contextual data; maintaining a hydration level of the transdermal alcohol sensing device; and any other suitable processes. A system for monitoring intoxication of a user including a sensor and a housing. The system can additionally or alternatively include any or all of: an inlet, a fastener, an electronics subsystem, a user device, and/or any other suitable component.

A sweat sensor device (200) includes one or more sweat sensors (220) and a seal (280) covering the one or more sweat sensors (220). The seal (280) is adapted to protect the sweat sensors (220) from outside contaminants when the device (200) is placed on the skin (12). The sweat sensor device (200) may include an absorbing medium (230) to absorb sweat from the skin (12) that is covered by the seal (280). The seal (280) can be permeable to gas, permeable to water and impermeable to at least one aqueous solute, or selectively permeable to at least one aqueous solute. The sweat sensor device (200) may include an artificial sweat stimulation mechanism (345) for stimulating sweat when the device (200) is placed on the skin (12).

Transdermally emitted gasses are detected by applying a dermal sampling strip to the skin of a biological subject, capturing the gasses in a vapor space in the dermal sampling strip, and analyzing for at least one such gas captured in the vapor space of the dermal sampling strip. Analysis is preferably performed using an electrocatalytic cell, which can be mounted on the dermal sampling strip and form a wall of the vapor space.

Methods, kits and systems described herein provide collecting, preparing, processing and/or analyzing a clinical sample, such as a blood. The methods, kits and systems may use a biocompatible solution comprising water and a stabilizing solvent, such as isopropanol, for accurate testing of the presence and/or amount of dmg, nutrient, or metabolite.
