Abstract: An electronic cigarette vaporiser system including a cartridge designed to provide a liquid or other substance for the electronic vaporiser system, the cartridge including a chip that stores data related to the batch number of the substance stored in the cartridge, and the cartridge being adapted to be inserted into or form an integral part of the electronic vaporiser system. The electronic vaporiser system reads the data from the chip and compares that data with stored data and, depending on the result of that comparison, either prevents or permits use of that substance.

Abstract: An electronic cigarette vaporizer includes a heating element and a microcontroller; the microcontroller monitors or measures external or ambient temperature and uses that as a control input. The control input automatically controls the power delivered to the heating element to ensure that the heating element operates at its optimal temperature. Where ambient temperatures are monitored or measured as very cold, then the power to the heating element is automatically increased to compensate.

Abstract: An electronic cigarette vaporiser that includes a heating element and further includes or co-operates with an electronics module that (i) detects characteristics of the delivery of power, current or voltage to the heating element and (ii) determines if those characteristics are associated with degradation of the heating element. A characteristic that is associated with degradation of the heating element is an increase or other change in the heating element resistance. The heating element resistance can be established by the electronics module sending a test current through the heating element that is sufficient to enable a measurement of resistance to be made.

Abstract: An electronic cigarette vaporiser system includes a piezo-electric pump (6) with multiple piezo-actuators, in which a microcontroller independently adjusts the phase or timing or power of each voltage pulse that triggers a piezo-actuator. The microcontroller continuously or regularly monitors the efficiency or performance of the entire pump (6) and adjusts the phase, timing, or power delivered to each piezo-actuator relationship until or so that the optimum pumping performance is achieved.

Abstract: A wearable electronic device includes a wristband; a detachable electronic module adapted to fit into the wristband, the module including a controller, a control button, a tactile sensor, a wireless interface adapter, and a tactile event reproduction element, all connected to the controller. The module is configured to transmit a touch or a tap on the tactile to a second wearable device through the wireless interface adapter, and to receive a notification of a tactile event on the second wearable device through the wireless interface adapter and to reproduce the tactile event using the reproduction element. The tactile sensor can be an accelerometer, a MEMS, a gyroscope, a capacitive sensor or a resistive sensor. The network adapter can be a Bluetooth adapter or ANT+ standard-enabled, and connects to a smartphone or a tablet. The network adapter connects to the second device over the Internet via a server.
