4762 results about "Flashlight" patented technology

A flashlight (more often called a torch outside North America) is a portable hand-held electric light. The source of the light is usually an incandescent light bulb (lamp) or light-emitting diode (LED). A typical flashlight consists of the light source mounted in a reflector, a transparent cover (sometimes combined with a lens) to protect the light source and reflector, a battery, and a switch. These are supported and protected by a case.

Method and apparatus for total situational awareness and monitoring

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.

Optical device for repositioning and redistributing an LED's light

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.

Method of pose estimation and model refinement for video representation of a three dimensional scene

The present invention is embodied in a video flashlight method. This method creates virtual images of a scene using a dynamically updated three-dimensional model of the scene and at least one video sequence of images. An estimate of the camera pose is generated by comparing a present image to the three-dimensional model. Next, relevant features of the model are selected based on the estimated pose. The relevant features are then virtually projected onto the estimated pose and matched to features of the image. Matching errors are measured between the relevant features of the virtual projection and the features of the image. The estimated pose is then updated to reduce these matching errors. The model is also refined with updated information from the image. Meanwhile, a viewpoint for a virtual image is selected. The virtual image is then created by projecting the dynamically updated three-dimensional model onto the selected virtual viewpoint.

Electrified handguard

An electrified handguard for firearms has mounting rails and also supplies electrical power to rail mounted accessories such as flashlights and lasers. A handguard power coupler can receive electrical power from a battery or other power source located elsewhere such as in a buttstock assembly. The electrical power is then routed to power connections in the handguard power coupler. A rail accessory can then be electrically connected to a power connection when it is mechanically attached to a mounting rail.

Method and System for Performing Video Flashlight

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.

Reducing shared downlink radio channel interference by transmitting to multiple mobiles using multiple antenna beams

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.

Light switch assembly

A light switch assembly to replace an existing light switch, which generally includes a mounting bracket attached to an electrical box. The assembly slides into the mounting bracket and is locked into place with the mounting bracket. A decorative light switch cover and custom artwork within the frame snaps and locks onto the outer perimeter of the mounting bracket to complete the assembly. The assembly provides for a battery hack-up system for power failure situations to illuminate the white, light emitting diodes in the event of a loss of power. The assembly senses the loss of power and unlocks the switch assembly from attachment to the mounting bracket. Unsnapping the decorative cover exposes the switch assembly so it can be removed from the mounting bracket. The switch assembly then becomes a mobile, hand-held emergency flashlight. The battery back-up system also allows for communication with first responders.

A signaling light, such as a wand light or flashlight, includes a motion sensor coupled to a controller for lamp intensity. When the light is moved in a first direction, the lamp is powered at a baseline intensity. When the light is moved in a second direction generally opposite the first direction, the lamp is switched off or dimmed. When swung in a back-and-forth motion, the light as controlled by the controller thereby appears to move in only one direction, thereby providing a signal indicating a direction of motion.
