There are provided an apparatus and method for photographing an object. An apparatus for photographing an object using top and bottom buttons includes: a head part including a camera; a connection part coupled to the head part and extended in a length direction thereof, and having a first button for manipulating the camera on an extension line in the length direction from a formation position of the head part and a second button for manipulating the camera formed on a surface opposite to the first button; and a body part including a power source means coupled to the connection part and supplying power to the camera, and a display means displaying a state of the camera or a power state.

An injection locked transmitter for an optical communication network includes a master seed laser source input substantially confined to a single longitudinal mode, an input data stream, and a laser injected modulator including at least one slave laser having a resonator frequency that is injection locked to a frequency of the single longitudinal mode of the master seed laser source. The laser injected modulator is configured to receive the master seed laser source input and the input data stream, and output a laser modulated data stream.

A smart light source configured for visible light communication. The light source includes a controller comprising a modem configured to receive a data signal and generate a driving current and a modulation signal based on the data signal. Additionally, the light source includes a light emitter configured as a pump-light device to receive the driving current for producing a directional electromagnetic radiation with a first peak wavelength in the ultra-violet or blue wavelength regime modulated to carry the data signal using the modulation signal. Further, the light source includes a pathway configured to direct the directional electromagnetic radiation and a wavelength converter optically coupled to the pathway to receive the directional electromagnetic radiation and to output a white-color spectrum. Furthermore, the light source includes a beam shaper configured to direct the white-color spectrum for illuminating a target of interest and transmitting the data signal.

The present image generator visually suppresses a gap between two adjacent reflective surfaces of a reflective display. The image generator comprises memory and a processor. The memory stores position of the gap on the reflective display. The processor analyses a stream of images to be displayed on the reflective display and determines corresponding lighting data alongside the gap. The processor further controls at least one lighting unit located behind a seam inserted in the gap based on the determined lighting data.

An information display device including a display displays content for conveying content to a user configured to adapt the content conveyed to the user by changing the content displayed on the display based on a received or determined detection result.

A method for enabling indoor positioning of a mobile receiver, including: detecting an orientation of the mobile receiver; measuring light intensities using at least three effective visible light receiving areas positioned on the mobile receiver, wherein the at least three effective visible light receiving areas are orientated such that a measurement of light intensity of a light from the same light source by each of the at least three effective visible light receiving areas is different from the others; and producing an output which enables a 3-dimensional indoor positioning of the mobile receiver relative to a second coordinate system.

An LED may be optimized for high speed operation for optical communication systems in a variety of ways. The LED, which may be a microLED, may include dopants and dopant levels allowing for increased speed of operation, the LED may include interlayers, and the LED may include other features.

A power pedestal includes a pedestal member including a base structured to be fixed to a platform and an enclosure extending from said base, a plurality of input power terminals mounted to said pedestal member and structured to be electrically connected to a power source, a number of output power receptacles mounted to said enclosure, a number of circuit interrupters having a ground fault detection capability and being structured to output an alarm signal in response to detecting a ground fault, a relay structured to receive the alarm signal from the circuit interrupters and to output an indicator signal, and an indicator unit structured to receive the indicator signal from the relay, the indicator unit including an indicator and being structured to illuminate the indicator in response to receiving the indicator signal.

An electronic device may be provisioned with an infrared (IR) light-emitting diode (LED) configured to externally transmit identifying information that particularly identifies the device, such as the device serial number, to outside of the device. A companion portable IR LED reader may be used to systematically scan a row or shelf or rack of electronic devices to read the respective communication signals transmitted from each of the respective devices, thereby enabling quick and accurate physical identification of the devices in a system/datacenter and inhibiting the unnecessary removal of an incorrect or misidentified device for replacement.
