Apparatus and methods are described for use with a vaporizer that vaporizes at least one active ingredient of a material. In response to receiving a first input to the vaporizer, the material is heated, in a first heating step. An indication of the temperature of the material is detected, and, in response to detecting an indication that the temperature of the material is at a first temperature, the first heating step is terminated, by withholding causing further temperature increase of the material. The first temperature is less than 95 percent of the vaporization temperature of the active ingredient. Subsequently, a second input is received at the vaporizer. In response thereto, the material is heated to the vaporization temperature, in a second heating step. Other applications are also described.

The present invention relates to a device for identifying the connection status between a patient catheter and a cassette system having flexible tubing assembly, which is intended to be used in a dialysis machine, wherein the device comprises the cassette system having flexible tubing assembly and an electrical circuit, which is disposed on the cassette system having flexible tubing assembly as well as on the patient catheter, and wherein the device furthermore comprises a measuring device for measuring at least one electrical property of the electrical circuit, which depends on said connection status.

A device is described for delivering a therapeutic vibration to a body. The device may include at least two motors in a housing with unbalanced masses coupled to their axles, such that vibration of the masses causes the two motors and housing to vibrate at a beat frequency 80. The motors and housing may be coupled to the body via a platform which places the motors and housings at or near a resonant structure in the body, creating a coupled oscillation between the platform and the body. The vibration may be based on the input signal, such that the system applies the vibration based on the input signal to the user, wherein the signal may be an audio or video signal. The system may be configured to measure and manipulate the flow of cerebral spinal fluid.

A system for carbon dioxide (CO2) removal from a circulatory system of a patient includes a medical device providing extracorporeal lung assist (ECLA) treatment to the patient through extracorporeal removal of CO2 from the patient's blood; at least one control unit controlling the operation of the medical device so as to control a degree of CO2 removal obtained by the ECLA treatment; and a bioelectric sensor detecting a bioelectric signal indicative of the patient's efforts to breathe. The at least one control unit is configured to control the operation of the medical device based on the detected bioelectric signal.

Certain aspects of the present disclosure provide methods and apparatus for measuring an injection catheter needle insertion depth and/or injection solution efficacy. An example injection catheter may include a catheter tube and a retractable, electrically conductive needle disposed in the catheter tube and configured to extend from the catheter tube. The injection catheter may also include one or more electrodes disposed at a distal portion of the catheter tube, an electrical lead coupled to the needle, and electrical leads coupled to the electrode(s). An example method includes deploying such an injection catheter adjacent to the tissue, extending a needle into the tissue, receiving electrical signals from an electrical lead coupled to the needle and from other electrical leads coupled to the electrode(s), determining a bioelectrical parameter based on the received electrical signals, and determining a depth of the needle inserted into the tissue based on the bioelectrical parameter.

The invention relates to an evaporator unit for an inhaler, in particular an electronic cigarette product, comprising an electrically operable heating body, in particular a flat heating body, which has an inlet side and an outlet side, and a plurality of microchannels, each of which extends from the inlet side to the outlet side through the heating body. The heating body is designed to evaporate liquid being transferred through the microchannels by applying a heating voltage. A porous and/or capillary wick structure is arranged on the inlet side of the heating body, said wick structure being fluidically connected or connectable to a liquid store. The wick structure has a shaft which extends through a passage opening of the support, and a collar, which is arranged between the support and the heating body, wherein the diameter of the collar is greater than the diameter of the passage opening of the support.

An aerosol generating device which is capable of generating an aerosol at an appropriate timing includes: a power source which supplies power in order to atomize an aerosol source and/or heat a flavor source; a sensor which outputs a measurement value for controlling the power supplied; and a controller which controls the power supplied on the basis of the measurement value. The controller controls a power supply amount from the power source to be a first value when the measured value is equal to or larger than a first threshold and smaller than a second threshold larger than the first threshold, and the power supply amount to be larger than the first value when the measured value is equal to or larger than the second threshold.

Methods and systems are provided for assisting a user of a wearable biosignal monitoring device (2) in adjusting the device to achieve optimum fit and positioning. The biosignal monitoring devices considered use integrated bio sensors (5) to monitor the user’s physiological activity for various purposes such as tracking daily activity patterns, determining mood, and monitoring sleep stages, among others. It is determined either during device setup or during primary use of the device whether the current fit and positioning of the device (2) enable the bio sensors (5) to properly sense the physiological signals needed for the device to perform its primary function. The user is then informed either after initial device setup whether adjustments need to be made in order to optimize device function during primary use, or is informed after primary use whether adjustments need to be made in order to improve device function during future primary use.
