A sentient system combines detection, tracking, and immersive visualization of a cluttered and crowded environment, such as an office building, terminal, or other enclosed site using a network of stereo cameras. A guard monitors the site using a live 3D model, which is updated from different directions using the multiple video streams. As a person moves within the view of a camera, the system detects its motion and tracks the person's path, it hands off the track to the next camera when the person goes out of that camera's view. Multiple people can be tracked simultaneously both within and across cameras, with each track shown on a map display. The track system includes a track map browser that displays the tracks of all moving objects as well as a history of recent tracks and a video flashlight viewer that displays live immersive video of any person that is being tracked.

An optical device is for spatially displacing the output of a light-emitting diode (LED) and coupling the output to a predominantly spherical emission pattern produced at a useftul height above the LED. The device is made of a transparent dielectric material, such as an injection-molded plastic. It comprises a lower transfer section that receives the LED's light from below and an upper ejector section that receives the transferred light and spreads it spherically. One or more LEDs. are optically coupled to the bottom of the transfer section, which operates by total internal reflection upon their entire hemispherical emission. One embodiment operates as a flashlight-bulb substitute with the ejector section radiating onto a parabolic reflector, which forms the beam. Thus hemisphencally emitting LEDs can be used in parabolic-mirror flashlights wherein these LEDs by themselves may be unsuitable for that role.

In an immersive surveillance system, videos or other data from a large number of cameras and other sensors is managed and displayed by a video processing system overlaying the data within a rendered 2D or 3D model of a scene. The system has a viewpoint selector configured to allow a user to selectively identify a viewpoint from which to view the site. A video control system receives data identifying the viewpoint and based on the viewpoint automatically selects a subset of the plurality of cameras that is generating video relevant to the view from the viewpoint, and causes video from the subset of cameras to be transmitted to the video processing system. As the viewpoint changes, the cameras communicating with the video processor are changed to hand off to cameras generating relevant video to the new position. Playback in the immersive environment is provided by synchronization of time stamped recordings of video. Navigation of the viewpoint on constrained paths in the model or map-based navigation is also provided.

The instant invention provides a convertible lighting device featuring a battery housing and a detachable lamp assembly. The lighting device can be operated in flashlight and headlamp modes.

An illuminating beverage container cooler. The sleeve of the cooler is made of a flexible thermally insulating material, such as neoprene, and the base of the cooler is made of a rigid material with lights and necessary batteries installed within a containment compartment in said base. The lights, when turned on, result in the portion of the bottle above the insulating cylindrical sleeve sidewalls being illuminated. The illuminating cooler also functions as a flashlight when the beverage container is removed.

A Light device having built-in Camera to operate desire digital data functions is powered by an power source for a lamp-holder, light source, flashlight or light device connected to power source by prongs or a bulb-base with conductive contacts to get power. The device may take the form of an IP cam, or Driving Cam, or webcam having but not limited add for auto tracking or one of plurality functions to make different products and functions with optional retractable prongs that plug directly into a wall outlet or insert into existing lamp base or incorporate conductive wire to make electric connection at least one of built-in camera, storage unit, wireless kits, Bluetooth kits, APP communication unit, motion sensor, light device. The said motion sensor and digital data related device(s) including but not limited all kind of camera may in separated housing with night-vision assembly selected from light source, IR diodes, low light camera lens & IC & circuits so people can upgrade the non-camera device to has built-in camera and digital device for their old non-camera security light. The motion sensor head or PIR has digital data output to work with wireless communication parts to avoid the analog model for mutual interfere the signals to cause false functions of light source or wifi or APP or wireless related functions.

A radio base station includes multiple antennas associated with a cell. Multiple mobile radios are selected to receive transmissions over a shared radio channel during a predetermined time interval. Information is transmitted over the shared radio channel to multiple mobile radios in the cell during the predetermined time interval using multiple antenna beams. As a result, interference from the transmission appears as white additive Gaussian noise in time and in space in the cell. A “flashlight effect” caused by a single beam transmission over the shared channel during a predetermined time interval that would normally detrimentally impact mobile channel quality detection is avoided. Other methods for avoiding the flashlight effect are described.

A flashlight having an elongated body having opposed first and second ends. A first lamp is a high-intensity variable brightness white light source located at the first end. A number of additional lamps are positioned at the first end. The additional lamps include at least two different output wavelengths different from each other and from the first lamp. A first switch on the flashlight selectively operates to select the output wavelength of the flashlight by selectively enabling different lamps based on the condition of the switch. A power storage element and control circuitry are connected to the lamps and to the switch.

A flashlight has a lamp, a power source, two switches, and a controller connected to the switches. The first switch controls delivery of power to the lamp, and the second switch selects a dimmed brightness level. The first switch may invoke the dimmed level, or a maximum brightness level. The second switch may be a ring rotatable about the axis the flashlight, and either rotatable through a wide range of positions, with sensor circuitry to detect the absolute position, or having a limited range of rotation, with dimmed level selection provided by a duration of momentary rotation in either direction. The second switch may be positioned outside a leak resistant housing, and may include a magnet detectable by magnetic field sensors within the chamber.
