A control body is coupleable with a cartridge to form an aerosol delivery device, with the cartridge being equipped with an electrical load. The control body includes first and second positive conductors connectable with respectively a power supply and the electrical load. The control body includes a series pull-up resistor and switch connected to and between the first and second positive conductors. A microprocessor is configured to operate the switch in a closed state in a standby mode in which the pull-up resistor causes a logical high level of voltage at the second positive conductor when the control body and cartridge are uncoupled, and in which the electrical load is unpowered causes a logical low level of the voltage when the control body and cartridge are coupled. The microprocessor is configured to measure the voltage and control operation of functional element(s) of the aerosol delivery device based thereon.

Load-based detection of an aerosol delivery device in an assembled arrangement

The present disclosure provides an aerosol delivery device. The aerosol delivery device comprises one or more rechargeable batteries, charging circuitry including an electrical connector configured to interconnect the one or more rechargeable batteries with a power supply, and a sensor configured to detect an action of using the aerosol delivery device by a user and output a signal. The aerosol delivery device also comprises a microprocessor coupled to the charging circuitry and the sensor, the microprocessor, in response to receiving the signal from the sensor, is configured to control the aerosol delivery device to allow vaping or puffing by a user while the aerosol delivery device is connected to a charger.

Charging control for an aerosol delivery device

A control body is coupleable with a cartridge to form an aerosol delivery device, with the cartridge being equipped with a heating element. The control body includes first and second positive conductors connectable with respectively a power supply and the heating element. The control body includes a series pull-up resistor and switch connected to and between the first and second positive conductors. A microprocessor is configured to operate the switch in a closed state in a standby mode in which the pull-up resistor causes a logical high level of voltage at the second positive conductor when the control body and cartridge are uncoupled, and in which the heating element is unpowered causes a logical low level of the voltage when the control body and cartridge are coupled. The microprocessor is configured to measure the voltage and control operation of functional element(s) of the aerosol delivery device based thereon.

An aerosol delivery device is provided that includes a power source, a heating element, a switch coupled to and between the power source and the heating element, and processing circuitry coupled to the switch. The processing circuitry outputs a PWM signal during a heating time period to cause the switch to switchably connect and disconnect the output voltage to the heating element to power the heating element. The processing circuitry outputs a pulse of known current to the heating element, and measure voltage across the heating element, between adjacent pulses of the PWM signal. And the processing circuitry calculates the resistance of the heating element based on the known current and the voltage, calculates the temperature of the heating element based on the resistance, and adjusts a duty cycle of the PWM signal when the temperature deviates from a predetermined target.

Temperature control in an aerosol delivery device

An electronic device includes a housing that encloses a controller and/or other electronic components, a display viewable through a face of the housing that is configured to display an alphanumeric character list, and an input device adjacent the display that is movable by a user to highlight and select respective alphanumeric characters in a displayed character list. To highlight characters within a displayed character list, the input device is rotatable about an axis that is substantially normal to the display and is slidable within a plane that is substantially orthogonal to the axis. In some embodiments, the input device is rotatable and slidable within a plane that is substantially parallel with a plane defined by the housing face. To select a highlighted character, a user depresses the input device.

A USB bus-powered device in Suspend state that requires active bus state power levels, but has no data transfer need, may initiate Resume signaling to return a USB bus segment to active state, without transferring any data across the bus. A device driver considers both USB device power needs and data transfer activity in deciding to Globally or Selectively Suspend a bus or bus segment. In particular, upon deciding to Suspend a bonus or bus segment, the device driver queries a USB bus-powered device. If the device will require active bus mode power within a predetermined duration, the device will indicate to the device driver to remain an active mode. In this case, the device driver does not direct the USB host to Suspend the bus.
