Abstract: A system and method for sensing and indicating air pressure within an enclosed space is described. The system comprises a pressure sensing device and pressure indicator further comprising a housing enabled to house a plurality of electronic devices and having an opening, an elastomeric membrane covering the opening of the housing and capable of flexing inwards and outwards, a light emitting device to provide an illumination and a projector for projecting a positive pressure symbol and a negative pressure symbol. The elastomeric membrane flexes inwards along with a representation of the positive pressure symbol with an illumination of a first color when the pressure within the enclosed space is positive and the elastomeric membrane flexes outwards along with a representation of the negative pressure symbol with the illumination of a second color when the pressure within the enclosed space is negative.

Abstract: Case accessories for portable electronic devices are disclosed. In some embodiments, a case accessory may include a base configured to sit on a working surface, a support coupled to the base and configured to support a portable electronic device in an elevated position, a rotational mechanism coupled to the support configured to allow the holder to rotate in one or more directions relative to the support, and a holder coupled to the rotational mechanism and configured to secure the portable electronic device.

Abstract: An actuator for a HVAC system includes a base having a motor and a drive device driven by the motor and configured to be coupled to a movable HVAC component for driving the movable HVAC component between multiple positions, and a removable cartridge removably attached to the base.

Abstract: A building control system includes a sensor unit, a space controller, and a controlled device. The space controller is configured to operate one or more controlled devices to affect one or more environmental conditions of a first space of a building. The sensor unit is communicably coupled to the space controller and is configured to be disposed in the first space. The sensor unit includes one or more sensors. The sensor unit is configured to determine an environmental condition of the first space based on sensor data from the sensor and configured to provide at least some of the sensor data to the space controller. The controlled device is communicably coupled to the sensor unit and is operable to affect the environmental condition of the first space. The sensor unit is configured to control the controlled device independently from the space controller.
