A lighting device is provided, a plurality of light sources are located within a housing of the lighting device. A sensor is also provided to determine an indication of the point of lowest potential energy and/or the point of highest kinetic energy. This sensor output is input to a controller that is configured to determine a change in the position or a movement of the point of lowest potential energy and/or the point of highest kinetic energy as the position of the lighting device changes based on the sensor output and to change a property of the light emitted by the plurality of light sources based on the change of position or a movement of the point of lowest potential energy and/or the point of highest kinetic energy.

A system for respiratory training including a housing, a respiratory air channel disposed within the housing, a sensor configured to detect a breathing indicator and transmit a breathing indicator signal, a haptic device disposed within the housing, a processor operatively coupled to the sensor and the haptic device, and a memory device operatively coupled to the processor. The memory device includes instructions that, when executed by the processor, cause the processor to receive the breathing indicator signal from the sensor; generate a breath determination based on the breathing indicator signal; and responsive to the breath determination, cause the haptic device to generate a vibration.

A tuneable expiration positive airway pressure (TEPAP) apparatus (10) comprises an entrainment valve (12) and a module (14), fluidly coupled with an outlet port (60) of the entrainment valve, for tuning an inspiration-to-expiration pressure transition of the breath cycle. The entrainment valve (12) includes a housing (56), an upstream inlet port (58), a downstream outlet port (60), and a valve (62). The valve (62) enables inspiration airflow between an exterior the housing (56) and the inlet port (58) during inspiration and prevents expiration airflow between the inlet port (58) and the exterior of the housing (56) during expiration. The tuning module (14) facilitates at least one rate-of-change in pressure of the inspiration-to-expiration pressure transition that is non-instantaneous. The at least one non-instantaneous rate of change in pressure is selected from among different non-instantaneous rates-of-change in pressure of the inspiration-to-expiration pressure transition.

An athletic mouthguard with lung exercising variable, two-way airflow-restricting valve is disclosed. The mouthguard has a mouthpiece with a lower tooth bed and an upper tooth bed overlying the lower. Outer and an inner sidewall connects the beds. A channel passes between the lower and upper beds with a first end open within the inner sidewall and a second end open within the outer sidewall. Certain embodiments include a channel wall which separates the channel into multiple channels. A manifold in fluid communication with the channel terminates to a centralized aperture with a valve seat. A rotatable valve member in the valve seat has an aperture therethrough.

Presented is a portable hand held e-cigarette shaped oxygen generator and air purifier. The device includes a suction body through which atmospheric air is forcibly introduced within a main body of the device during respiration, a solid oxygen filter adapted for holding solid oxygen, and a solid oxygen filter support having a dual cylindrical structure for housing and supporting the solid oxygen filter. The device further includes a solid oxygen filter support lid mountable over the solid oxygen filter support and is adapted for discharging device generated inhalable oxygen from the main body to a micro filter, a casing embodying the micro filter and operationally connected to a mouthpiece having an extension for mounting a straw. The atmospheric air introduced in the device reacts with the solid oxygen to generate inhalable oxygen after passing the atmospheric air through the dual cylindrical structure of the solid oxygen filter support.

An altitude simulator controls a percentage of oxygen within an enclosed environment to simulate altitude. A controller of the altitude simulator determines a set altitude to be simulated within the enclosed environment and determines an oxygen percentage setpoint based upon the set altitude. The altitude simulator senses, at intervals, environmental parameters of the enclosed environment. The altitude simulator may determine, from the environmental parameters, an oxygen percentage value indicative of a percentage of oxygen in air of the enclosed environment. The altitude simulator feeds hypoxic air into the enclosed environment from an air unit and controls a ventilation fan to maintain the oxygen percentage value at the oxygen percentage setpoint.
