The projector circuit mounts in the bulb structure. The personal data device controls the operation of the projector circuit.

A rechargeable flashlight configured to communicate via a wireless network, and associated systems and methods are disclosed herein. In some embodiments, the rechargeable flashlight includes a light emitter configured to generate light outputted by the flashlight and an imaging device configured to capture environmental data from an area exposed to the output light. The flashlight can also include a cylindrical handheld main body that includes one or more functionally distinct modules configured to be detachably coupled together to provide coordinated operation. The flashlight can also include at least one user-controlled switch operable to control operation of one or more of the interchangeable cylindrical modules.

An example stand for an electronic device includes a base, a column extending upward from the base, a camera coupled to the column, and an interface supported on the column that is to engage with the electronic device to suspend the electronic device on the column.

A display system and a control method are provided. The display system includes a display device, an illumination device and a control circuit. The display device includes a display panel. The display panel is configured to display an image frame. The illumination device is movably disposed on the display device. The illumination device selectively projects light in a first direction or in a second direction different from the first direction. When the illumination device projects the light in the first direction, the control circuit generates a first control signal so as to control the illumination device to perform a first illumination mode. When the illumination device projects the light in the second direction, the control circuit generates a second control signal so as to control the illumination device to perform a second illumination mode different from the first illumination mode.

The present disclosure relates to a portable solid-state drive (SSD) module. The portable SSD module includes a case, an SSD, a light-emitting device (LED) module and a main bracket. The case may have a window. The SSD may be arranged in the case. The LED module may be arranged in the case to indicate an operation of the SSD through the window. The main bracket may be arranged in the case to support the LED module. Therefore, the LED module may be readily and firmly combined with the case.

A planar light source includes a wiring substrate including an insulating layer comprising a first through-hole, a second through-hole, a first wiring layer, and a second wiring layer; a light source including a first electrode and a second electrode, a light guide member; a first wiring member including a first portion filling the first through-hole and electrically connected to the first electrode and a second portion disposed below the insulating layer, continuous with the first portion, and in contact with the first wiring layer; and a second wiring member including a third portion filling the second through-hole and electrically connected to the second electrode and a fourth portion disposed below the insulating layer, continuous with the third portion, and in contact with the second wiring layer. The first and second wiring layers are arranged at opposite sides of the first and second through-holes in a top plan view.
