For example, a pointer operation control portion can be configured to control an operation of a pointer driving motor such that the pointer moves on a dial of the display device at different moving speeds according to the air-conditioning operating state.

A thermostat may be placed in a heating mode when the sensed temperature is less than the lowest of the heating and cooling target temperatures by a first amount and may be placed in a cooling mode when the sensed temperature is greater than the highest of the heating and cooling target temperatures by a second amount. The presence or absence of a user may be monitored. If the thermostat is in a user absent mode, a cool setback amount may be added to the cooling target temperature and a heat setback amount may be subtracted from the heating target temperature to arrive at setback cooling and setback heating target temperatures, respectively. The thermostat may comprise a touch-sensitive screen having various display areas.

A hybrid manual / programmable thermostat for a furnace or air conditioner offers the simplicity of a manual thermostat while providing the convenience and versatility of a programmable one. Initially, the hybrid thermostat appears to function as an ordinary manual thermostat; however, it privately observes and learns a user's manual temperature setting habits and eventually programs itself accordingly. If users begin changing their preferred temperature settings due to seasonal changes or other reasons, the thermostat continues learning and will adapt to those changes as well. For ease of use, the thermostat does not require an onscreen menu as a user interface. In some embodiments, the thermostat can effectively program itself for temperature settings that are set to occur at particular times daily or just on weekends, yet the user is not required to enter the time of day or the day of the week.

A visual display system for use with a menu driven digital thermostat is provided. The visual display system provides a relative indication of the total number of menu items in the displayed menu on the thermostat's user interface display. A relatively sized and positioned scroll bar is utilized in one embodiment to provide such relative visual cue to a user of the position of the currently selected menu item and the total number of menu items available in the list. Directional icons may also be utilized to provide as visual cue regarding which way within the list the user is able to maneuver during operation. Both vertical and horizontal scroll bars and / or directional icons may be provided.

An air conditioning apparatus for a vehicle seat includes a seat blower unit disposed in a lower side of the seat, and a seat duct for leading air from an air conditioning unit to the seat through the seat blower unit. In the air conditioning apparatus, it can be determined that heat load of a passenger compartment is decreased to a predetermined value based on an operation state of a unit blower of the air conditioning unit, and the seat blower is stopped when the heat load is decreased to the predetermined value. Further, the seat blower is turned on or off according to the heat load of the passenger compartment, so that temperature of the seat can be controlled within a predetermined range. On the other hand, even when the unit blower is stopped when a water temperature of a heating unit of the air conditioning unit is lower than a set temperature, the seat blower unit and an electrical heater disposed in the seat duct are operated so that air passing through the heating unit is heated by the electrical unit and is blown into the seat by the seat blower unit.

An intelligent thermostat communicates with threat detectors to allow periodic remote testing of the detector. The real-time clock and calendar functions of the thermostat allow the consumer to program the day, time, and frequency of the testing. The thermostat then communicates a test control signal to each of the detectors to initiate the self-test. The communication may be wired or wireless. During testing the thermostat displays a detector test screen. Upon completion of the self-test, the thermostat displays a test results screen for user confirmation. This results screen will indicate that the test passed or failed along with any diagnostic information provided by the detector. The thermostat also provides a test initiation screen from which the consumer may initiate a detector self-test manually. Loss of communications with a detector is also communicated to the user, as is the location of the detector that first identified a threat.

Heat may be transferred from a plurality of galley food carts to the circulating liquid coolant.

In an anti-hijacking system for autopilot equipped aircraft, a transceiver communicates with at least one remote guidance facility. A panic button is activated by flight crew in case of hijacking. A manager is coupled to the transceiver and the panic button, as well as existing avionics including the aircraft's master computer and autopilot. Optionally, a relay is coupled between the pilot controls and selected aircraft flight systems. The manager recognizes predetermined override inputs, such as activation of the panic button or receipt of override signals from the remote guidance facility. Responsive to the override input, the manager deactivates on-board control of selected aircraft flight systems and the autopilot system, and directs the autopilot to fly the aircraft to a safe landing. Flight routing and landing instructions are obtained from the remote guidance facility, or by self-evaluating nearby airports in view of the aircraft's position and various preestablished criteria.

A passenger cabin of a passenger transport vehicle such as an aircraft includes single passenger seats arranged between an aisle and an outside cabin wall. Each seat is tiltably adjustable between an upright seating configuration and a reclined lying configuration, and is rotatable between a forward-facing orientation facing 0 to 18° relative to the cabin longitudinal axis, and an inwardly-turned orientation facing 50 to 600 relative to the longitudinal axis. The forward-facing orientation is for upright seating during take-off and landing. The inwardly-turned orientation provides additional leg room and sufficient space for the reclined lying configuration. The pitch spacing between seats can be minimized, and total seating capacity is high, while providing substantial space and comfort for each passenger. Screening partitions adjacent to the cabin wall and the aisle provide privacy screening and define a personal space allocated to each seat.

Light diffusers and ceiling panels in a “wing-shape” and other secondary panels are utilized to create different interior designs and structures. A permeable secondary panel is utilized in one passenger cabin in order to provide a more private-type space. An enlarged ceiling arch with blended curves forming a “wing-type” configuration provides a more spacious cabin arrangement. Other features include air and light diffusers, passenger service modules, a “shelf”-like configuration and lighting above the airplane entrance / exit door, and bulkheads and monuments positioned at various positions in the cabin.

A vehicle seating arrangement can comprise a fore-facing lower seating assembly, an aft-facing lower assembly, and an upper seating assembly positioned between the fore-facing and aft-facing lower assemblies.
