Detecting objects in video data
Certain examples described herein enable semantically-labelled representations of a three-dimensional (3D) space to be generated from video data. In described examples, a 3D representation is a surface element or ‘surfel’ representation, where the geometry of the space is modelled using a plurality of surfaces that are defined within a 3D co-ordinate system. Object-label probability values for spatial elements of frames of video data may be determined using a two-dimensional image classifier. Surface elements that correspond to the spatial elements are identified based on a projection of the surface element representation using an estimated pose for a frame. Object-label probability values for the surface elements are then updated based on the object-label probability values for corresponding spatial elements. This results in a semantically-labelled 3D surface element representation of objects present in the video data. This data enables computer vision and/or robotic applications to make better use of the 3D representation. |

Spectrum analyzer with increased real-time bandwidth
Conventional real-time spectrum analyzers have a degree of technical complexity in the hardware which increases disproportionately as the analysis bandwidth increases for Fourier transformations of the measured sampling values. When using high analysis bandwidths, a detailed resolution is not needed of each analyzed individual frequency on the time plane at the same time; instead, detection of the presence of short pulses can be important as well. For this application, mixing sampling values on the time plane using a variable auxiliary frequency allows the sampling rate to be reduced, in that the bandwidth is maintained but a compression is carried out on the time plane. A very high time resolution which far exceeds the capabilities of conventional real-time spectrum analyzers can additionally be achieved overall for the analysis bandwidth, the time resolution then being computationally assignable to the individual frequencies for signal forms, in particular pulses, which occur in practice. |

A heat dissipating portion in the miner's lamp includes a substrate, a reflector, and heat sinks; the substrate provided with a first through-hole in the center thereof is arranged on an inner wall of the reflector; an upper surface of the substrate is provided with a plurality of the heat sinks; the substrate, the reflector, and the heat sinks are integrated during casting; the power source cover is provided with a latching switch and is arranged on the reflector; the reflector is provided with a lens whose center is a recessed blind via; the lens is located on a side of a lower surface of the substrate, a ring protrusion is provided around the recessed blind via, and a sensor is arranged in the recessed blind via; the lens, the reflector, and the power source cover form a cavity; a driving power source fixed to the substrate is arranged in the cavity; and the lower surface of the substrate is provided with a light emitting element corresponding to the ring protrusion. In the present invention, the latching switch is arranged on the power source cover. Before the miner's lamp is mounted, whether the miner's lamp has a sensing function can be controlled by using the latching switch. In this way, use of other lamps of the same type is not affected, the costs are low, and mounting, cable layout, and subsequent maintenance are easy. |

Guide light irradiation device
A guide light irradiation device to irradiate guide light to indicate a direction to a survey operator, includes a plurality of irradiators configured to each irradiate guide light differing in pattern between the left and the right of an irradiation direction as a center, the plurality of irradiators are juxtaposed in a left-right direction, and irradiation units of the plurality of irradiators are disposed so that the irradiation units match in the horizontal direction, and optical axes of the plurality of irradiators make a predetermined angle with each other in the vertical direction. Synthetic light of the respective guide lights has brightness obtained by summing brightnesses of the light sources of the respective irradiators, and has a fan shape extending in the vertical direction. A distance at which the light is visually recognized is long, and the guide light is easily found even at a location with level differences. |

Vehicle lamp installation method and assembly
A vehicle lamp installation method includes, among other things, engaging both a mounting bracket and an outer panel of a vehicle with an alignment fixture that locates the mounting bracket relative to the outer panel in a mounting position. The method further includes securing the mounting bracket to a body structure of the vehicle when the mounting bracket is in the mounting position. A vehicle assembly includes, among other things, a body structure of a vehicle, a mounting bracket secured to the body structure in a mounting position, and an outer panel secured to the body structure. The mounting bracket is located in the mounting position relative to the outer panel using an alignment fixture that engages with both the outer panel and the mounting bracket. |

Lighting system with replaceable downlight
A lighting system having a LED downlight in a ceiling fixture can be attached to a ceiling by fixing hanger bars to ceiling rafters. The lighting system can then be completely covered by insulation. The insulation thereby lays directly on the downlight, junction box, and a cup passing mains power from the junction box to the downlight. The insulation does not enter the cup, downlight, or junction box. The lighting system does not ignite or melt the insulation in normal operation if the insulation meets residential and commercial safety standards. In normal operation the lighting system does not expose the lighting system to a temperature exceeding 90 degrees Celsius. A trim can be attached to the downlight to change its appearance and without rendering the lighting system unsafe. |

Light string package structure
A lighting structure including a light-transmitting cap, a wire, a light emitting diode (LED) and a transparent adhesive. Two guide pieces project in parallel and protrude from the bottom of a body of the light-transmitting cap, and an opening of the body is located between the two guide pieces. Two lugs extend from the body, and correspond to two ends of a guide trench between the two guide pieces. A soldering surface of the LED is soldered on a soldering section of the wire. The transparent adhesive wraps around the soldering section, the guide trench and the two lugs, and wraps around a light emitting surface of the LED. The light-transmitting cap covers the LED with the LED at the opening. The soldering section is located between the two guide pieces, and the transparent adhesive attaches the LED to the light-transmitting cap. |
