For the user interface, as seen in
During the setting operational mode 34, the user can set the system into a programming mode by pushing the programming button 42, on the front of the panel 44 located below the day of the week LCD interface 30. To change the previously set settings, the user can utilize the directional buttons 46, which include a scroll up button 48, a scroll down button 50, a scroll right button 52, and a scroll left button 54.
The user will use the above-mentioned directional buttons to scroll between the various selectable areas. The currently selected area or in other words (the hot area or the highlighted area) can be chosen. The highlighted area would be defined as any of the user interface settings that can be accessed and changed by the user. Once the user moves to the desired highlighted area, the user can use the close increment setting button 40, or the open increment setting button 38 to change the desired setting. To save the change and exit the program, the user simply pushes the program button 42 once again.
An operational process will now be discussed utilizing a control application 212, as seen in
After accessing the control application 212 through the user interface, the user can set the current time component at step 310. This includes various sub steps such as holding the time button down for one second at step 312, then selecting the hours or minutes at step 316 for changing the hour and minute clock, then pressing the time button again at step 320 to save and exit.

Referring to
In replacement of a standard vent cover, a top cover 124 is provided which enables the user to have access to the LCD and controller panel 126 through the use of an LCD panel cover 128. The air vents 130 are placed on either side of the vent LCD panel cover 128. The surface area, which is maintained by the LCD panel cover 128, is approximately one quarter of the entire surface area provided by the top cover 124.
While the LCD controller panel 126 in this particular embodiment is maintained within the top cover 124 of the air vent, and maintained within the general path of the airflow exiting the air vent port, other embodiments provided herein, as seen in
Referring to
Referring to
While the embodiments discussed herein and described below with regard to the mechanical operation of the air vent cover regulate the airflow through either a sliding louvered two-piece system 150 as seen in
Furthermore, the current embodiment as seen in
Thus air flow is minimally impacted by the insertion of the LCD controller 126 and the unit itself. In one embodiment, the battery cover and battery compartment are placed so that the batteries can be accessed from the top cover 124. In a second alternative embodiment, the battery cover is located along the sidewall 136 of the unit casing 140. The unit casing 140 or main box 140 has a rectilinear configuration which matches the standard rectilinear configuration of the vent and ductwork which is standard in the industry.
Where the bottom wall would normally be to close off the main box 140, gear vents 100 are placed to enable the opening and closing of the bottom wall surface 142 to allow the opening and closing of the unit through the actuation of the gear system and the gear box 122.
In an alternative embodiment to the vents (as shown in
In this particular embodiment, the gear mechanisms 160 will mate with horizontally aligned downwardly projecting vertical teeth 162 on the bottom face of the dynamic section 154. The dynamic section 154 will be able to move in the longitudinal direction 164 enabling the dynamic section walls 166 to be aligned with the horizontal walls 158 of the static section 152 while also providing for alignment of the dynamic section openings 168 with the static vent openings 156 to provide for air flow.
The dynamic section 154 can be moved incrementally by the radially aligned teeth of the gears 160 to the previously mentioned ¼ close setting, ½ close setting, ¾ close setting, full close setting, or full open setting. During the full close setting, the gears 160 move the dynamic section 154 to align the dynamic section walls 166 with the static section openings 156 to close off the air flow from the vent.
Referring to
Power to the system is sent from the battery current lines 264 to the controller which, as previously discussed and seen in
A number of signal operators send and receive analog current information which is then processed by the controller. The signal operators include an open breaker 256, a close breaker 254, as well as a midpoint breaker 257. When the open event signal is sent to the motor from the controller, the current through the motor current lines 250 moves in the open direction which then enables the motor to actuate the cylindrical gear teeth 262 and rotate along the linear gear track 260 fixedly attached to the dynamic moving section 154 (
Similarly, when the controller is operating the motor in the close direction, the breaker post 252 will initiate physical contact with the close breaker 254 which sends a signal to the controller that the dynamic moving section 154 has reached the desired close location for the vents.
In order to maintain a half open or have close position, a midpoint breaker post 258 is arranged to initiate a stop current signal to the controller when the linear gear track 260 initials contact with the midpoint breaker post 258.
While the present embodiment has three breaker sensors, other arrangements can achieve the same desired control. For example, maintaining the open and close currents for a specific period of time which correlates to periods of rotation of the cylindrical gear teeth 262 along the linear gear track 260. Also, providing fewer or additional breakers within the particular system to maintain more or less incremental opening and closing distances.
In operation, the user may set the current time and date for the first time the user uses the unit. Afterwards, the second step includes the user programming the unit to set the opening setting for different time periods of the day and different days of the week. Optionally, in the second alternative embodiment, the user will set the opening and closing settings for different parts of the day only. The unit will is provided with certain factory presets. Lastly in the third step, the user will simply replace the current vent located in the household or building, with the provided vent unit to control the air flow out of the ductwork to the particular space. The unit is thus designed to have the same overall dimension as previously mentioned, and to thus directly replace the current vent cover being used for most of standard ductwork in US households.
