A base structure for a water ball ornament includes a hollow and transparent main body and an opening facing upward, the opening in connection with a water ball ornament, an inner wall of the main body covered with a patterned back plate, one side of the main body provided with a photo frame holder, the photo frame holder configured with a slot and a window in communication with the slot, the slot allowing a photo to be inserted in, and the photo being directly visible through the window.

The present invention relates generally to the field of campfires and fireplaces. More specifically, the present invention relates to a fire sign device primarily comprised of at least one stand and at least one sign. The stand can be placed within a campfire or a fireplace via an attachment mechanism that includes, but is not limited to: a clamp, a stake, a stand, etc., which may further be repositionable on the stand and adjustable. The sign further attaches to the stand and may be comprised of at least one indicia that is made from a heat-resistant thermochromic paint that becomes visible when heated. In a differing embodiment, the sign is shaped like the indicia itself. One embodiment of the device includes at least one LED within the indicia that illuminates when a temperature sensor of the device detects a temperature above a threshold value.

A pop-up having a glass bow are produced by shining a point light source on a reflective and refractive surface. The pop-up with a glass bow might be incorporated into a card or a book.

A self-contained illuminated sign for mounting on a vehicle is disclosed. The sign includes a front panel, a rear panel situated opposite and substantially parallel to the front panel in spaced relation therefrom to define a space therebetween, and a light source comprising a plurality of LEDs. The light source is positioned between the front and rear panels and is configured to emit light that emanates from the front panel. The front panel is thus backlit to display indicia. A system for supporting a self-contained illuminated sign on a vehicle is also disclosed. The system includes the sign and a separate mounting frame mountable on a vehicle. The mounting frame is configured to removably receive the sign and, when the sign is received in the mounting frame, to surround a perimeter of the sign while permitting visibility of the front display area. Related methods are also disclosed.

An illuminated sign for use in a vehicle wash system, including a base, an upright member extending from the base and having an upper portion and a lower portion, and a head portion connected to the upper portion of the upright member. The illuminated sign includes at least one light source having a first mode and a second mode. The first mode is associated with a first group of vehicle wash services for treating an exterior of a vehicle. The second mode is associated with a second group of vehicle wash services for treating an exterior of a vehicle. The sign includes a sign controller in communication with the at least one light source. The sign controller is configured to enable the first mode in response to detecting a selection of the first group of vehicle wash services. The sign controller is also configured to enable the second mode in response to detecting a selection of the second group of vehicle wash services.

The present invention provides a method of setting light emission control of each light emission tool in an area more easily. The method of setting light emission control of each light emission tool in an area of the present invention includes: a light emitting step of transmitting a freely-selected ID signal (S.sub.n) to a plurality of light emission tools that are randomly disposed in an area and emit light in response to receipt of corresponding ID signals to cause a light emission tool (E.sub.n) that has received the ID signal (S.sub.n) to emit light; an imaging step of acquiring a light emission image (E.sub.n) of the area after the ID signal (S.sub.n) has been transmitted; a determining step of determining a position of the light emission tool (E.sub.n) that emitted light in response to receipt of the

ID signal (S.sub.n) in the area based on the light emission image (E.sub.n); and a storing step of storing the position of the light emission tool (E.sub.n) in the area and the corresponding ID signal (S.sub.n) in association with each other.

To allow a smartphone and a tag to cooperate in searching for a suitcase, this suitcase search system comprises a smartphone, an application function unit which is implemented by an application program, and a tag attached to a suitcase. The smartphone comprises a display device, an input device, and two communication devices. The application function unit comprises a connection verification device and a suitcase lifting prevention device. The tag comprises: two communication units which correspond with the two communication devices of the smartphone; a light emitting unit; a control unit; and a power supply unit. The control unit controls each of a connection establishment mode, a sleep mode, and a wake-up mode. In the wake-up mode, the light emitting unit is caused to emit light at a blink interval which corresponds to the strengths of two radio waves.

The light emitting unit is provided with a light guiding plate. The light guiding plate comprises an acrylic plate and a film adhered to the acrylic plate, and functions as an identification marker for the possessor of the tag. It is desirable for a power switch of the tag to be locked.
