A device may be configured to control a heating, ventilation, and air conditioning (HVAC) system within a building. The device includes a rotatable dial comprising a first gear; a second gear configured to engage with the first gear, wherein a rotation of the first gear causes the second gear to rotate; a magnet placed on the second gear, wherein the magnet rotates with the second gear; a sensor configured to generate an electrical signal which indicates a rotational position of the magnet, wherein the rotational position of the magnet indicates the rotational position of the second gear; and processing circuitry. The processing circuitry is configured to receive, from the sensor, the electrical signal which indicates the rotational position of the second gear; and change a temperature set point based on a change in the rotational position of the second gear.

A cooking appliance is adapted to perform either as a single large fan-forced convection oven capable of cooking a larger food, or as smaller independently-operable fan-forced convection ovens each capable of cooking smaller foods. Features of the cooking element arrangement provide faster, more efficient, and higher quality results regardless of the size and amount of food being cooked.

A cooking appliance includes a housing that defines a cooking cavity. A first temperature sensor is coupled to the housing and is configured to detect an air temperature of the cooking cavity. A rack is disposed within the cooking cavity and includes a second temperature sensor that is coupled to a frame of the rack.

A moveable graphical user interface object is provided. The moveable graphical user interface object is moveable within a bounded graphical region. A current location of the moveable graphical user interface object in the bounded graphical region corresponds to an indicated direction of concentrated airflow. For example, the moveable graphical user interface object is used to control airflow direction of a HVAC air vent.

A heating station for use with, for example, a high speed parallel manufacturing line for manufacturing insulated glass units, the heating station including at least two opposing infrared heaters that linearly heat spacer material that includes integrated temperature sensitive adhesive. Each of multiple linear infrared heaters includes a respective associated temperature sensor. The infrared heater and temperature sensor are coupled to a spacer heating controller that controls intensity and/or duration of heating of the spacer material and adhesive to provide optimal wetting and adhesive qualities. Individual control of the at least two opposing linear infrared heaters compensates for variable environmental conditions affecting spacer material at different locations around and insulated glass unit.

In one embodiment, a remote monitoring system for a fluid applicator system is disclosed. The fluid applicator system is disposed to heat and pump spray fluid, and to transmit reports including sensed temperatures, pressures, and other operational parameters of the fluid applicator system via a wireless network. The remote monitoring system comprises a data storage server, and an end user interface. The data storage server is configured to receive and archive the reports. The end user interface is configured to provide a graphical user interface based on the reports. The graphical user interface illustrates a status of the fluid handling system, sensed and commanded temperatures of the fluid handling system, sensed and commanded pressures of the fluid handling system, and usage statistics of the fluid handling system.

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

One variation of a method for monitoring occupancy in a work area includes, at a sensor block: transitioning from an inactive state into an active state when an output of a motion sensor indicates motion in a work area; during a scan cycle in the active state, recording an image through an optical sensor at a time, detecting a set of humans in the image, detecting a second set of human effects in the image, predicting a second set of humans occupying but absent the work area based on the second set of human effects, and estimating a total occupancy in the work area at the time based on the set of humans and the second set of humans; and transmitting the total occupancy to a remote computer system for update of a scheduler for the work area.
