DETAILED DESCRIPTION OF THE INVENTION
(23) For convenience, one or more embodiments may be referred to herein as the “S-Wand” It should be noted, however, that some embodiments may reflect one or more other shapes (e.g., a rod with multiple sides, such as a hectogon, hexagon, etc., or other shaped housing) or non-wand-like objects. In some embodiments, the S-Wand may be operated by an app through a smart phone or operate automatically by pre-set conditions (e.g., time of day or conditions sensed by the S-Wand) or use of physical remote or if desired manually like a standard solid wand. The S-Wand may be powered by batteries or by an external power source via a cable (e.g., such as DC and solar).
(24) Various other aspects, features, and advantages of the invention will be apparent through other sections herein. It is also to be understood that both the foregoing general description and the following detailed description are examples and not restrictive of the scope of the invention.
(25) In certain embodiments, the S-Wand may include a tubular housing assembly 20, an electronics and motor insert assembly, an end cap assembly, a spindle coupling assembly, or other components (
(26) As shown in
(27) In some embodiments, as shown in
(28) The outer surface of tube 30 may be left in a natural material state or coated. In certain embodiments, coatings may include spray paint, powder coat, anodize, e-coat, electro-less nickel, etc. In alternative embodiments, although coatings may be applied, one or more specific areas may remain electrically conductive. As an example, if the coating is electrically isolating (e.g., paint), then the aforementioned areas may be uncoated. In one use case, the specific areas that remain electrically conductive may include countersunk holes 43b, internal thread 42, or other areas of tube 30. In certain embodiments, the present invention may provide for a shrinkable tube-like material that can be used with varying colors and patterns to give a unique appearance to the wand.
(29) In some preferred embodiments, as shown in further detail in
(30) Curved flange 52 is intended to be a bonding surface to adhere to tube 30 by a suitable adhesive. Alternative methods of attaching window 41a/42b to tube 30 could be used. In some embodiments, alternative methods may include a variety of attachment means, including snap in features, staked in place, ultrasonically welded, screws or other mechanical structural support. The small hole 53 shown is optional and could be used to access a switch with a paper clip or similar sized part. The circular pocket 54 on the inner portion of window 41a/42b creates a thin wall to allow light to be visible from an internal LED. Other features such as bosses 55 on the inner portion of window 41a/42b are optional to help with assembly.
(31) As shown in
(32) In certain embodiments, base component 61 is a single part made of plastic. In alternative embodiments, base component 61 is made of alternative materials. Base component 61 is, optionally, constructed of multiple pieces and a combination of materials.
(33) Base component 61 has many features, as further shown in
(34) As shown in
(35) Power input jack 87 is, preferably, a 3-circuit jack that allows for the S-Wand to be powered by external sources (e.g., DC power, solar power, or other sources). Power input jack 87 may be configured to allow the power source to come from only one power source at a time (and not multiple at a time). Power input jack 87 allows the S-Wand to automatically determine which form of power source is installed. Power input jack 87 has the capability of having two connections simultaneously and can decide which to use or automatically switch to another power source if one source is unusable. For example, if power input jack 87 has a plug inserted into it, and batteries within the wand are not usable or drained, power input jack 87 will draw AC power rather than power from the drained batteries (instead of being inoperable due to no battery power).
(36) Preferably, additional hardware elements are included on PCBA 62, including: an ambient light sensor, which captures the amount of light the wand can sense and react to various conditions; a LDO/PWM (Pulse Width Modulation) voltage regulator 3 v, which allows a consistent 3 volts and allows a set current to be provided to the motor, and as batteries drain, the motor will always get at least 3 volts resulting in consistent speed and torque; an accelerometer/gyroscope, which captures any movement in the wand in order to react, in real time, to different movements; a current sense, which captures current going to the motor; a diode, used for trickle-charging with solar power, to prevent any current flowing backward; a power barrel connector that allows for any power source to be plugged into the wand. In a further aspect, reverse power protection is provided to prevent damage to components in case of incorrect or improper battery installation.
(37) The current sense feature provides the ability to control the torque applied to the blinds via current sensing. Since there are many sizes of vertical and horizontal blinds, by adjusting the current delivered to the motor, the current sense will allow for torque to be adjusted so it will have sufficient power to turn the slats/louver of the blinds to open/close position. In some instances, the torque may need to be decreased for small and new blinds but increased for large or old blinds.
(38) Motor/encoder assembly 63 is further detailed in
(39) As depicted in

(49) In some embodiments, one or more computing devices may be programmed to perform the functions described herein. The computing devices may include one or more electronic storages, one or more physical processors programmed with one or more computer program instructions, and/or other components. The computing devices may include communication lines or ports to enable the exchange of information within a network or other computing platforms via wired or wireless techniques (e.g., Ethernet, fiber optics, coaxial cable, WiFi, Bluetooth, near field communication, or other technologies). The computing devices may include a plurality of hardware, software, and/or firmware components operating together. For example, the computing devices may be implemented by a cloud of computing platforms operating together as the computing devices.
(50) The electronic storages may include non-transitory storage media that electronically stores information. The storage media of the electronic storages may include one or both of (i) system storage that is provided integrally (e.g., substantially non-removable) with servers or client devices or (ii) removable storage that is removably connectable to the servers or client devices via, for example, a port (e.g., a USB port, a firewire port, etc.) or a drive (e.g., a disk drive, etc.). The electronic storages may include one or more of optically readable storage media (e.g., optical disks, etc.), magnetically readable storage media (e.g., magnetic tape, magnetic hard drive, floppy drive, etc.), electrical charge-based storage media (e.g., EEPROM, RAM, etc.), solid-state storage media (e.g., flash drive, etc.), and/or other electronically readable storage media. The electronic storages may include one or more virtual storage resources (e.g., cloud storage, a virtual private network, and/or other virtual storage resources). The electronic storage may store software algorithms, information determined by the processors, information obtained from servers, information obtained from client devices, or other information that enables the functionality as described herein.
(51) The processors may be programmed to provide information processing capabilities in the computing devices. As such, the processors may include one or more of a digital processor, an analog processor, a digital circuit designed to process information, an analog circuit designed to process information, a state machine, and/or other mechanisms for electronically processing information. In some embodiments, the processors may include a plurality of processing units. These processing units may be physically located within the same device, or the processors may represent processing functionality of a plurality of devices operating in coordination. The processors may be programmed to execute computer program instructions to perform functions described herein. The processors may be programmed to execute computer program instructions by software; hardware; firmware; some combination of software, hardware, or firmware; and/or other mechanisms for configuring processing capabilities on the processors.
(52) In a preferred embodiment, as shown in
(53)
(54) Optionally, the wand may be converted to manual use by untwisting tab 171 from a horizontal position to a vertical position in order to remove tab 171 from bracket 131. When a user sets up the wand for the first time or resets the system, the following will preferably occur. The user will position the slats or louvers to one end and the system activation will automatically move them to the other, extreme end. Once the system sees such a change in resistance, it will identify each extreme end and the encoder will track same by counting of the geared motor's shaft turns from one end to the other. Thus, the user will then have the ability to choose any position from one extreme end (0% open; 100% close) to the other (100% open; 0% close) or any position in between (30% open; 70% close, for example) for automation or remote use. Alternatively, the user may position the slats or louvers to one end and mark the position in the system by use of a physical button (remote control) or a virtual button (a phone or software app).
(55) The wand utilizes the accelerometer/gyroscope component to determine if the system was used manually or not. If the wand was last used manually, the system will conduct a full reset at the end of manual use or at the beginning of the next operation. When the system senses a sudden movement in any direction or a tilt position change that falls outside of the normal operation, it will interpret this as a manual use and the system will have to do a reset in order to have the accurate two end positions of the slats or louvers. The accelerometer/gyroscope component can work in any of methods described supra and the reset will be based on one of these methods unless an automatic safety halt is triggered.
(56) Preferably, bracket 131 is attached to a header or headrail of the set of blinds. Most preferably, antirotating element 150 is reversible, thereby being capable of use with a set of blinds having a left-hand or right-hand tilt mechanism assembly. In this embodiment, antirotating element 150 is adjusted by removing the two screws holding it in place and flipping antirotating element 150 in the desired position to allow tab 171 to be inserted through bracket 131. Similarly, if antirotating element 150 requires replacement, it may be detached and replaced by removing the two screws holding it in place, reattaching a new antirotating element, then replacing the two screws to complete reinstallation.
